Rankings were recomputed on October 14, 2026 under methodology v1.4: a brand now scores only in the answers that recommend it, while the consensus gate still counts every AI model that names it. The new supplier’s page capture repeated some Copilot list items; on October 19, 2026 those repeated copies were removed from the stored Copilot answers, with no other wording changed. The cleaning does not affect the ranking, and the regional root hash first published on October 9 is superseded by one computed over the cleaned answers.","answersEdited":true},"registryRulesHash":"95fd79a9a28e615bb1729e91d331e21de9c0c9b66bace2d66478105ed2261141","registryRulesHashSpec":"sha256-v1: hex SHA-256 of the UTF-8 bytes of the compact JSON object {version, aliases, notInCategory, categoryAllow, serviceSlugRe} where aliases is the array of [foldedKey, canonicalName, pinnedDomain, categoryScope] tuples sorted by key, carrying a fifth regionScope element only on the entries that have one, notInCategory and categoryAllow are arrays of [categorySlug, domains] tuples sorted by slug, and every domain/scope list is itself sorted, carrying a trailing notInCategoryByRegion element, an array of [categorySlug, region, domains] triples sorted by slug then region, only when at least one region-scoped deny entry exists, and after it a trailing notInCategoryByName element, an array of [categorySlug, regionScope, names] triples sorted by slug then scope (regionScope \"*\" for every board region, names as published), only when at least one name-scoped deny entry exists","region":"au","prompt":"What are the best cyber security companies in Australia?

a breakdown of Australia's cybersecurity landscape, split into **enterprise/business providers** and **consumer products** since \"best\" really depends on what you're protecting.\n\n## For Businesses & Enterprises\n\nAustralia has a strong local cybersecurity services industry, with a mix of homegrown firms and global players operating here:\n\n**Large-scale/Enterprise providers:**\n- **CyberCX** – One of Australia's largest cybersecurity firms, CyberCX has become a powerhouse after merging multiple regional experts, focusing on enterprise-level protection, security advisory, and government-grade solutions. It's one of the most recognised names for large organisations and critical infrastructure.\n- **Tesserent (now Thales Cyber Services ANZ)** – Known for managed security services, consultancy, threat intelligence, and GRC, with strong corporate and government ties and 24/7 monitoring capability.\n- **Gridware** – A Sydney-founded cyber security company operating as an ASD-accredited industry partner, giving it direct access to ACSC threat intelligence feeds. Strong reputation for penetration testing and incident response.\n\n**Specialist Australian players:**\n- **Airlock Digital** – An Adelaide-based company known for application whitelisting/control, widely used across government and defence due to its proactive prevention and defense against emerging threats.\n- **Kasada** – An Australian success story specialising in bot defence, protecting websites from automated attacks — used by major retailers and airlines globally.\n- **QuintessenceLabs** – Based in Canberra, it develops quantum cybersecurity technologies for organisations managing highly sensitive data, with growing relevance as quantum computing advances.\n\n**Global brands with a strong AU presence:** CrowdStrike (endpoint protection, heavily used by Australian enterprises), IBM Security, and Arctic Wolf (24/7 managed detection) also show up repeatedly in local market analyses.\n\n**Note on rankings:** Take \"top 10\" listicles with a grain of salt — many are published by the companies themselves or marketing agencies, so it's worth checking reviews, ASD/ACSC partnership status, and CREST/ISO 27001 accreditation rather than relying on any single \"best of\" list.\n\n## For Everyday Consumers / Home Use\n\nIf you're after personal protection rather than enterprise security, these are the products most commonly used by everyday Australians:\n\n- **Antivirus/Internet Security:** Norton 360, Bitdefender, and McAfee remain the most widely purchased consumer antivirus suites in Australia, often bundled with ISPs or retailers like JB Hi-Fi and Officeworks.\n- **VPNs:** NordVPN and ExpressVPN are the most popular choices for Australians wanting privacy, geo-unblocking, or protection on public Wi-Fi.\n- **Password Managers:** 1Password (very popular with Aussie businesses and individuals) and Bitwarden (free, open-source favourite) are widely recommended.\n- **Government-backed advice:** The Australian Cyber Security Centre (ACSC) via **cyber.gov.au** is the authoritative","extractedBrands":[{"name":"CyberCX","domain":"cybercx.com.au","position":1},{"name":"Tesserent","domain":null,"position":2},{"name":"Gridware","domain":null,"position":3},{"name":"Airlock Digital","domain":"airlockdigital.com","position":4},{"name":"Kasada","domain":"kasada.io","position":5},{"name":"QuintessenceLabs","domain":"quantumcyber.com","position":6},{"name":"CrowdStrike","domain":"crowdstrike.com","position":7},{"name":"IBM Security","domain":"ibm.com","position":8},{"name":"Arctic Wolf","domain":"arcticwolf.com","position":9},{"name":"Norton 360","domain":"norton.com","position":10},{"name":"Bitdefender","domain":"bitdefender.com","position":11},{"name":"McAfee","domain":"mcafee.com","position":12},{"name":"NordVPN","domain":"nordvpn.com","position":13},{"name":"ExpressVPN","domain":"expressvpn.com","position":14},{"name":"1Password","domain":"1password.com","position":15},{"name":"Bitwarden","domain":"bitwarden.com","position":16},{"name":"Australian Cyber Security Centre","domain":"cyber.gov.au","position":17}]},{"provider":"deepseek","run":1,"model":"deepseek-flash","capturedAt":"2026-10-14T09:45:16.107Z","text":"In Australia, there’s no single “best” cyber security company — it depends on whether you need a product, a managed SOC/MDR, or consulting. What you’ll actually see in Aussie enterprises, government, and mid-market is roughly this:\n\n## Top brands/products people actually use in Australia\n\n| Category | Commonly used in Australia |\n|---|---|\n| Endpoint / EDR / XDR | CrowdStrike Falcon, Microsoft Defender for Endpoint, SentinelOne, Sophos Intercept X, Trend Micro Apex One, Palo Alto Cortex XDR |\n| Firewall / Network | Fortinet FortiGate, Palo Alto Networks, Cisco, Check Point, Sophos |\n| Cloud Security | Microsoft Defender for Cloud, AWS GuardDuty/Security Hub, Wiz, Palo Alto Prisma Cloud, CrowdStrike Falcon Cloud Security |\n| Identity / Access | Microsoft Entra ID, Okta, CyberArk, SailPoint |\n| Email Security | Mimecast, Proofpoint, Microsoft Defender for Office 365, Abnormal Security, MailGuard |\n| SASE / Zero Trust | Zscaler, Netskope, Palo Alto Prisma Access, Cloudflare One, Cisco Umbrella |\n| SIEM / SOAR | Microsoft Sentinel, Splunk, IBM QRadar, Rapid7, Elastic Security |\n| Vulnerability Management | Tenable, Qualys, Rapid7 |\n| Security Awareness | KnowBe4, Phriendly Phishing |\n| MDR / Managed SOC | Arctic Wolf, CrowdStrike Falcon Complete, SentinelOne Vigilance, Sophos MDR, plus local MSSPs below |\n\n## Australian companies / MSSPs worth knowing\n- **CyberCX** — the largest Australian-headquartered cyber services firm. SOC, incident response, pentesting, Essential Eight, IRAP. Owns **MailGuard** and **Phriendly Phishing**.\n- **Tesserent (now part of Thales)** — major Aussie MSSP/SOC for enterprise and government.\n- **Sekuro** — Australian consultancy/MSSP; pentesting, cloud, identity, Essential Eight.\n- **Triskele Labs** — Melbourne-based 24/7 SOC/MDR, popular with mid-market.\n- **Shearwater Solutions** — Australian MSSP; SOC, IRAP, government work.\n- **StickmanCyber** — Australian MSSP focused on SMB/mid-market.\n- **Penten** — Canberra defence/cyber, secure comms.\n- **archTIS** — data-centric security for government/defence.\n- **Kasada** — Australian-founded bot/fraud defence, used globally.\n- **Secure Code Warrior** — Australian-founded secure coding training.\n- **Vault Cloud / Macquarie Government** — sovereign cloud/cyber for government.\n- Also common for consulting/managed services: **Deloitte, PwC, EY, KPMG, Accenture, IBM, NTT, Telstra, Data#3, AC3**.\n\n## What I’d shortlist by scenario\n- **Government/defence:** IRAP-assessed and sovereign. CyberCX, Tesserent, Shearwater, Penten, archTIS, Vault Cloud, Macquarie Government. Products: Microsoft, CrowdStrike, Palo Alto, Cisco, Fortinet, Splunk, CyberArk — but check IRAP status.\n- **Large enterprise:** Microsoft Defender/Sentinel/Entra, CrowdStrike Falcon, Palo Alto Cortex/Prisma, Fortinet, Cisco, Zscaler, Okta, CyberArk, Splunk, Tenable/Qualys.

Between the federal government’s goal to make Australia one of the most cyber-secure nations by 2030 and the heavy enforcement of the **ASD (Australian Signals Directorate) Essential Eight** framework, cyber security is top-of-mind for every local business.\n\nWhen looking at the best cyber security companies in Australia, it is best to divide them into three categories: **homegrown consulting and service giants (MSSPs)**, **locally built software products**, and the **global platforms** that Australian organisations actually run day-to-day.\n\n---\n\n### 1. The Top Homegrown Australian Cyber Service & Consulting Companies (MSSPs)\nIf you are looking for an external partner to manage your security, run penetration testing, monitor threats, or respond to an active breach, these are the leading local players:\n\n*   **CyberCX**  \n    *   **Who they are:** The undisputed behemoth of dedicated cyber security in Australia. Formed by consolidating dozens of the country's best boutique cyber firms, CyberCX is the go-to partner for major enterprises, federal/state government departments, and critical infrastructure. \n    *   **What they do best:** They offer a full-spectrum service: 24/7 managed Security Operations Centres (SOCs) strictly staffed onshore in Australia, high-level consulting, IRAP assessments for government compliance, and a highly regarded emergency incident response team.\n*   **Tesserent (Cyber Solutions by Thales)**  \n    *   **Who they are:** Formerly Australia’s largest ASX-listed cyber firm, Tesserent was acquired by global defence giant Thales in late 2023. It operates as the leading sovereign cyber capability for some of Australia's most sensitive defence and public sector programs.\n    *   **What they do best:** Deep expertise in government, critical infrastructure, and enterprise security. They have a massive local footprint, custom Security Operations Centres (including a dedicated government SOC in Canberra), and their own \"Tesserent Academy\" to train local cyber talent.\n*   **Gridware**  \n    *   **Who they are:** A premier, fast-growing Australian cyber security force based in Sydney. They are highly integrated into the national defence ecosystem as an ASD-accredited partner receiving direct threat intelligence feeds.\n    *   **What they do best:** Gridware is widely turned to for hands-on technical execution—specifically elite penetration testing, threat hunting, and rapid incident response (boasting a under-6-hour response SLA in major Australian cities). \n\n---\n\n### 2. Top Aussie-Built Cyber Security Software (Our Local Tech Successes)\nAustralia has produced some world-class cybersecurity software. If you want to buy and install \"Australian Made\" security products, these are the industry standards:\n\n*   **Airlock Digital (Application Control)**  \n    *   **What it is:** A native, Melbourne-founded endpoint security product.\n    *   **Why people use it:** Under the ASD’s \"Essential Eight\" guidelines, **Application Control** (allowlisting) is rated as the single most effective way to stop ransomware. However, it is notoriously difficult to configure. Airlock Digital solved this by making \"deny-by-default\" security incredibly easy to manage. It is heavily used by local councils, banks, and government agencies and is officially IRAP-assessed at the *PROTECTED* level.\n*   **Kasada (Anti-Bot & Fraud Protection)**  \n    *   **What it is:** A Sydney-founded startup that has taken on the global market.\n    *   **Why people use it:** If you run an e-commerce store, a ticketing site, or a portal with user logins in Australia, you get hit by bots constantly (scalping, credential stuffing, scraping). Kasada stops automated bot attacks and API fraud at the edge before they can even load, using an invisible, frictionless approach that doesn't rely on annoying CAPTCHAs.\n*   **UpGuard (Third-Party Risk Management)**  \n    *   **What it is:** An enterprise platform founded by Australians (with offices in Sydney and Hobart).\n    *   **Why people use it:** Modern businesses are only as secure as their weakest vendor. UpGuard is widely used across corporate Australia to continuously monitor and rate the security posture of third-party vendors and suppliers, helping organisations manage supply chain risk.\n*   **Bugcrowd (Crowdsourced Security & Pentesting)**  \n    *   **What it is:** Founded by Australian Casey Ellis, Bugcrowd pioneered the crowdsourced security market. \n    *   **Why people use it:** Instead of hiring a single firm to test your website, Bugcrowd connects you to a global crowd of vetted ethical hackers. It is widely used by Aussie tech companies and enterprises to run continuous Bug Bounty programs and Vulnerability Disclosure Programs (VDPs).\n\n---\n\n### 3. The Global Products Most Australian Businesses Actually Run\nWhile we have great local services and niche products, the day-to-day heavy lifting of corporate security in Australia relies heavily on a few trusted global giants:\n\n*   **Microsoft Security (Defender & Sentinel):** Because Australia is overwhelmingly a Microsoft/Azure-reliant business market, **Defender for Endpoint** (for antivirus/EDR) and **Microsoft Sentinel** (for SIEM/logging) are the most widely used enterprise security tools in the country. Many local MSSPs are built entirely around managing Microsoft's security stack.\n*   **CrowdStrike Falcon:** The gold standard for enterprise EDR (Endpoint Detection and Response) in Australia. Despite historical global outages, it remains deeply embedded in the Australian banking, retail, and corporate sectors because its threat-hunting capabilities are exceptionally strong.\n*   **Palo Alto Networks & Fortinet:** For network security and firewalls, Palo Alto is the premium, enterprise-grade choice for government and large corporates, while Fortinet is highly popular for mid-market and SME networks due to its strong balance of performance and price.\n*   **Mimecast:** The most ubiquitous email security filter in corporate Australia. Almost every mid-to-large business here routing Outlook or Google Workspace runs their mail through Mimecast to strip out phishing, spoofing, and malicious links.\n\n---\n\n### Local Buyer's Advice: How to Choose\nIf you are evaluating security partners or software here in Australia, keep these three factors in mind:\n1.  **Essential Eight Alignment:** Ask any prospective vendor how their service or product maps to the ASD Essential Eight maturity levels. If they cannot answer this clearly, they do not understand the local compliance landscape.\n2.  **Sovereign Data & Onshore SOC:** If you work in government, defence, healthcare, or financial services, check if your data stays in Australia. Look for providers with an onshore Security Operations Centre (SOC) that features \"eyes on glass\" 24/7 within Australian borders to comply with strict local privacy laws.\n3.  **IRAP Assessment:** If you are a public sector entity or supply to one, prioritize software and cloud systems that have completed an independent **IRAP (Information Security Registered Assessors Program) assessment**.","extractedBrands":[{"name":"CyberCX","domain":null,"position":1},{"name":"Tesserent","domain":null,"position":2},{"name":"Gridware","domain":null,"position":3},{"name":"Airlock Digital","domain":null,"position":4},{"name":"Kasada","domain":null,"position":5},{"name":"UpGuard","domain":null,"position":6},{"name":"Bugcrowd","domain":null,"position":7},{"name":"Microsoft Security","domain":"microsoft.com","position":8},{"name":"CrowdStrike","domain":"crowdstrike.com","position":9},{"name":"Palo Alto Networks","domain":"paloaltonetworks.com","position":10},{"name":"Fortinet","domain":"fortinet.com","position":11},{"name":"Mimecast","domain":"mimecast.com","position":12}]},{"provider":"google_ai_mode","run":1,"model":"google_ai_mode","capturedAt":"2026-10-14T09:45:16.107Z","text":"The best cybersecurity companies in Australia include homegrown industry giants like CyberCX and Tesserent, alongside highly utilized software vendors like Senetas and Prophecy International.

It is highly utilized for its comprehensive feature set, including anti-ransomware, dark web monitoring, and impersonation checks.\nOffice Solutions IT & Local MSPs: Most Australian SMEs utilize localized Managed Service Providers (MSPs)—such as Office Solutions IT or Canary IT—to deploy standard, everyday cloud architectures like the Australian Signals Directorate's (ASD) Essential Eight framework.\n\nAre you looking for a corporate cybersecurity partner to assess a local business network, or are you trying to find software products to secure endpoint devices?

([crestaustralia.org](https://crestaustralia.org/approved-companies?utm_source=openai))\n\n**Pick these if:** you want more specialised or boutique technical work, often with more direct access to senior testers than a giant consultancy.\n\n## Best products and brands people actually use in Australia\n\n### Endpoint / EDR / XDR\n**Top picks:**  \n- **CrowdStrike Falcon** — very common in enterprise and incident-response-led environments.  \n- **Microsoft Defender for Endpoint** — very common where the business already uses Microsoft 365 E3/E5/Business Premium.  \n- **SentinelOne** — strong alternative to CrowdStrike/Microsoft.  \n- **Sophos Intercept X** — common in MSP and mid-market environments.\n\nCrowdStrike, Microsoft and SentinelOne are all named in Gartner’s 2025 endpoint protection research, which is a good sign they are mainstream enterprise choices rather than niche products. ([gartner.com](https://www.gartner.com/en/documents/6718634?utm_source=openai))\n\n**My practical recommendation:**  \n- Microsoft 365-heavy SMB? Start with **Microsoft Defender for Business/Endpoint**.  \n- Higher-risk business? Shortlist **CrowdStrike vs Microsoft Defender for Endpoint vs SentinelOne**.  \n- MSP-managed SMB? **Sophos** and **Microsoft Defender** are often practical.\n\n### Firewalls, SD-WAN and SASE\n**Top picks:**  \n- **Fortinet FortiGate / FortiSASE** — extremely common in SMB, mid-market, education, retail and branch-heavy environments.  \n- **Palo Alto Networks** — common in larger enterprise and security-mature environments.  \n- **Check Point** — strong enterprise firewall option.  \n- **Cisco Meraki** — good for simpler distributed networks, especially where ease of management matters more than deep firewall sophistication.\n\nFortinet, Palo Alto Networks and Check Point are the main names you’ll repeatedly see in enterprise firewall shortlists and analyst rankings. ([sdxcentral.com](https://www.sdxcentral.com/news/fortinet-palo-alto-networks-top-gartners-hybrid-mesh-firewall-rankings/?utm_source=openai))\n\n**My practical recommendation:**  \n- SMB/mid-market: **Fortinet**.  \n- Enterprise/security-led: **Palo Alto**.  \n- Simple multi-site: **Meraki**.  \n- Existing Check Point shop: don’t rip it out without a strong reason.\n\n### Email security\n**Top picks:**  \n- **Microsoft Defender for Office 365** — default add-on for Microsoft 365 environments.  \n- **Proofpoint** — strong enterprise email security.  \n- **Mimecast** — common in business email security and archiving.  \n- **MailGuard** — Australian-founded email security provider, often seen in local SMB/MSP contexts.\n\nMailGuard is Australian-founded and focuses on cloud email security for phishing, ransomware, spear-phishing and business email compromise protection. ([mailguard.com.au](https://www.mailguard.com.au/?utm_source=openai)) Proofpoint was also named a Leader in Gartner’s 2025 Magic Quadrant for Email Security. ([proofpoint.com](https://www.proofpoint.com/us/newsroom/press-releases/proofpoint-named-leader-2025-gartner-magic-quadrant-email-security?utm_source=openai))\n\n**My practical recommendation:**  \n- Microsoft 365 small business: start with **Defender for Office 365**.  \n- More phishing/BEC exposure: compare **Proofpoint, Mimecast and MailGuard**.  \n- Want Australian support/local flavour: include **MailGuard**.\n\n### Identity, MFA and device management\n**Top picks:**  \n- **Microsoft Entra ID + Intune** — the default for Microsoft 365 businesses.  \n- **Okta** — strong independent identity platform, especially for mixed SaaS environments.  \n- **Cisco Duo** — simple MFA and device trust, often used by SMB/mid-market.  \n- **YubiKey / hardware security keys** — best for admins, executives, finance teams and high-risk accounts.\n\nFor Australian small businesses, ASD/ACSC guidance prioritises MFA, software updates and backups as key baseline measures. ([cyber.gov.au](https://www.cyber.gov.au/learn-basics/explore-basics/small-business?utm_source=openai))\n\n**My practical recommendation:**  \nIf you’re in Microsoft 365, use **Entra ID MFA + Conditional Access + Intune** before buying another identity tool.\n\n### SIEM, SOC and detection\n**Top picks:**  \n- **Microsoft Sentinel** — natural fit if you already use Microsoft Defender, Entra, Azure and Microsoft 365.  \n- **Splunk** — strong enterprise SIEM, often used in large/security-mature environments.  \n- **CrowdStrike Falcon Next-Gen SIEM / LogScale** — attractive if you already standardise on CrowdStrike.  \n- **Palo Alto Cortex XSIAM/XDR** — strong for Palo Alto-centric environments.\n\nSplunk and Microsoft Sentinel are both widely recognised SIEM options, with Splunk named a Leader in Gartner’s 2025 SIEM research and Microsoft promoting Sentinel as a Gartner-recognised SIEM leader. ([splunk.com](https://www.splunk.com/en_us/blog/security/splunk-named-leader-in-2025-gartner-siem-report.html?linkId=869489631&utm_source=openai))\n\n**My practical recommendation:**  \n- SMB: don’t run your own SIEM unless you have staff to monitor it. Buy MDR/SOC service.  \n- Microsoft-heavy business: **Microsoft Sentinel + managed SOC**.  \n- Enterprise: evaluate **Splunk vs Sentinel vs CrowdStrike vs Palo Alto Cortex**.\n\n### Application control / Essential Eight uplift\n**Top pick:** **Airlock Digital**\n\nAirlock Digital is Australian-founded and focuses on application allowlisting/control — particularly relevant because application control is one of the ASD Essential Eight controls. ([airlockdigital.com](https://www.airlockdigital.com/about?utm_source=openai))\n\n**My practical recommendation:**  \nIf an insurer, government contract or board is asking about **Essential Eight maturity**, put **Airlock Digital** on the list alongside Microsoft Intune/App Control options.\n\n### Secure developer training\n**Top pick:** **Secure Code Warrior**\n\nSecure Code Warrior was founded in Australia and is widely used for secure coding training and developer security uplift. ([securecodewarrior.com](https://www.securecodewarrior.com/company/about-us?utm_source=openai))\n\n**My practical recommendation:**  \nUse it if you have internal software teams and want to reduce vulnerabilities before code reaches production.\n\n### High-assurance encryption\n**Top pick:** **Senetas**\n\nSenetas is an Australian cyber/defence technology company focused on certified high-assurance network encryption for governments, defence, critical infrastructure and regulated environments. ([senetas.com](https://www.senetas.com/?utm_source=openai))\n\n**My practical recommendation:**  \nNot for normal SMBs. Consider it for classified, government, defence, critical infrastructure or high-assurance data-in-transit use cases.\n\n### Bot mitigation / web abuse protection\n**Top pick:** **Kasada**\n\nKasada was founded in Australia and focuses on bot defence, account abuse, fraud and web/API protection. ([kasada.io](https://www.kasada.io/about-us?utm_source=openai))\n\n**My practical recommendation:**  \nConsider Kasada if you run high-traffic consumer web apps, ecommerce, ticketing, travel, marketplaces, fintech or login-heavy services.\n\n## Home and very small business recommendations\n\nFor a normal Australian household or sole trader:\n\n1. **Use Microsoft Defender/Windows Security** if you’re on Windows 10/11 and keep it updated. ACSC notes that many small businesses can stay protected with Windows Security. ([cyber.gov.au](https://www.cyber.gov.au/learn-basics/explore-basics/small-business?utm_source=openai))  \n2. If you want a paid antivirus suite, shortlist **Bitdefender, ESET, Norton or Malwarebytes**.  \n3. Use a password manager: **1Password, Bitwarden, Dashlane or Keeper**.  \n4. Turn on MFA everywhere, especially email, banking, accounting software and remote access.  \n5. Back up to cloud plus an external/offline copy.  \n6. For business email, use **Microsoft 365 Business Premium** rather than a cheap email-only plan.\n\n## My blunt shortlist\n\nIf I were advising an Australian business, I’d usually start here:\n\n### Small business, 5–50 staff\n- **Microsoft 365 Business Premium**\n- **Defender for Business**\n- **Intune**\n- **Entra ID MFA**\n- **MailGuard / Defender for Office 365 / Mimecast** for email\n- **Fortinet or Meraki** for network\n- Local MSP or MDR provider\n\n### Mid-market, 50–500 staff\n- **Microsoft Defender for Endpoint or CrowdStrike**\n- **Microsoft Sentinel with managed SOC**\n- **Fortinet or Palo Alto**\n- **Proofpoint/Mimecast/MailGuard**\n- **CyberCX, Macquarie, Thales/Tesserent, Telstra or Sekuro** for advisory/testing/managed security\n\n### Enterprise / regulated / government-facing\n- **CyberCX / Thales / Telstra / Macquarie Government / Accenture / Big Four cyber**\n- **CrowdStrike or Microsoft Defender for Endpoint**\n- **Palo Alto or Fortinet**\n- **Proofpoint**\n- **Splunk or Sentinel**\n- **Airlock Digital** if Essential Eight maturity is a serious requirement\n- CREST-accredited pen testing and incident response retainer\n\n## Final advice\n\nFor Australia, choose based on **Essential Eight alignment, local support, CREST accreditation, incident response capability, Microsoft 365 integration, and whether the provider can actually operate 24/7 in your time zone**. The “best” stack for most Australian organisations is usually not exotic: **Microsoft + CrowdStrike/SentinelOne + Fortinet/Palo Alto + Proofpoint/Mimecast/MailGuard + a good local SOC/MDR provider**.","extractedBrands":[{"name":"Microsoft","domain":"microsoft.com","position":1},{"name":"Bitdefender","domain":null,"position":2},{"name":"ESET","domain":null,"position":3},{"name":"Norton","domain":null,"position":4},{"name":"Malwarebytes","domain":null,"position":5},{"name":"Microsoft 365","domain":"microsoft.com","position":6},{"name":"MailGuard","domain":"mailguard.com.au","position":7},{"name":"Mimecast","domain":null,"position":8},{"name":"Proofpoint","domain":null,"position":9},{"name":"Macquarie Cloud Services","domain":"macquariecloudservices.com","position":10},{"name":"Telstra","domain":"telstra.com.au","position":11},{"name":"CyberCX","domain":"cybercx.com.au","position":12},{"name":"Thales Cyber Services ANZ","domain":null,"position":13},{"name":"The Missing Link","domain":null,"position":14},{"name":"Deloitte","domain":null,"position":15},{"name":"PwC","domain":null,"position":16},{"name":"KPMG","domain":null,"position":17},{"name":"EY cyber","domain":null,"position":18},{"name":"Accenture Security","domain":null,"position":19},{"name":"Gridware","domain":null,"position":20},{"name":"Borderless CS","domain":null,"position":21},{"name":"Dvuln","domain":null,"position":22},{"name":"Sekuro","domain":null,"position":23},{"name":"Fortinet","domain":"fortinet.com","position":24},{"name":"Palo Alto Networks","domain":"paloaltonetworks.com","position":25},{"name":"Check Point","domain":null,"position":26},{"name":"Cisco","domain":"cisco.com","position":27},{"name":"Meraki","domain":null,"position":28},{"name":"CrowdStrike Falcon","domain":"crowdstrike.com","position":29},{"name":"SentinelOne","domain":"sentinelone.com","position":30},{"name":"Sophos","domain":"sophos.com","position":31},{"name":"Microsoft Sentinel","domain":null,"position":32},{"name":"Splunk","domain":"splunk.com","position":33},{"name":"Airlock Digital","domain":"airlockdigital.com","position":34},{"name":"Secure Code Warrior","domain":"securecodewarrior.com","position":35},{"name":"Senetas","domain":"senetas.com","position":36},{"name":"Kasada","domain":"kasada.io","position":37}]},{"provider":"perplexity","run":1,"model":"sonar","capturedAt":"2026-10-14T09:45:16.107Z","text":"For Australians, the strongest shortlist combines **local security providers** with widely deployed global platforms. The best choice depends on whether you need a managed security team, business protection, or personal antivirus.\n\n## Best Australian cybersecurity companies and providers\n\n- **CyberCX** — One of Australia’s largest locally headquartered cyber firms, offering penetration testing, incident response, consulting, managed detection and response, and security operations. A strong choice for government, large enterprises and critical infrastructure.\n- **Tesserent / Thales Cyber Services ANZ** — Australian cyber consulting, managed security and incident-response capabilities, particularly relevant to government and regulated organisations.\n- **Sekuro** — Provides enterprise cloud, identity and cyber-security services, often alongside Microsoft, Cisco and other major platforms.\n- **Tesserent’s Airlock Digital** — Australian application-control technology used to restrict which software can run on business endpoints.\n- **Secure Code Warrior** — Australian-founded developer-security training platform used by organisations to find and fix software vulnerabilities earlier.\n- **MailGuard** — Australian email-security provider focused on phishing, malware, business-email compromise and Microsoft 365 protection.\n- **Kasada** — Australian-founded bot and automated-threat protection platform used by online businesses and financial services.\n- **Huntress** — Not Australian-owned, but increasingly used by Australian managed-service providers for small and medium businesses because it combines endpoint monitoring, managed detection and response, and Microsoft 365 protection.\n\nCyberCX, Tesserent/Thales, CrowdStrike, Cisco, Palo Alto Networks, Darktrace, Fortinet, Sophos, Microsoft Security and Secure Code Warrior are among the best-known brands associated with the Australian market.[1]\n\n## Products people commonly use\n\n| Need | Recommended products |\n|---|---|\n| Microsoft 365 business security | **Microsoft Defender for Business**, Defender for Office 365, Entra ID MFA and Intune |\n| Endpoint protection for larger businesses | **CrowdStrike Falcon**, **Microsoft Defender for Endpoint**, **SentinelOne Singularity** |\n| Firewalls and office networks | **Fortinet FortiGate**, **Cisco Secure Firewall**, **Palo Alto Networks** |\n| Small-business managed security | **Huntress**, **Sophos**, **Microsoft Defender for Business** |\n| Email and phishing protection | **Microsoft Defender for Office 365**, **MailGuard**, **Mimecast**, **Proofpoint** |\n| Security monitoring and SOC services | **CyberCX**, **Arctic Wolf**, **CrowdStrike**, **Huntress**, local managed-service providers |\n| Personal antivirus | **Bitdefender**, **ESET**, **Norton**, **Microsoft Defender**; Bitdefender is a strong general-purpose pick for Australian home users.[2][3] |\n\n## Practical recommendations\n\n- **Australian small business already using Microsoft 365:** Start with Microsoft Defender for Business, Defender for Office 365, MFA through Entra ID, automatic updates and managed backup. Add MailGuard, Mimecast or Proofpoint if email fraud is a major concern.[2]\n- **Business with no in-house security team:** Use an Australian managed-security provider such as CyberCX, or a reputable local IT provider using Huntress, Sophos, Microsoft or CrowdStrike.\n- **Mid-sized or large enterprise:** Shortlist CyberCX, Tesserent/Thales, CrowdStrike, Palo Alto Networks, Microsoft Security and Fortinet; require 24/7 monitoring, Australian incident-response support and clear service-level agreements.\n- **Government or regulated organisation:** Prioritise providers that can demonstrate relevant Australian Government security experience, IRAP assessment where required, data-residency options and incident-response capability.\n- **Home users:** Microsoft Defender is usually sufficient on current Windows devices if updates, MFA and backups are configured.
