Built In’s August 24, 2026 article highlights 11 cybersecurity companies for readers exploring employers and career options in Australia. The list ranges from consulting and incident response to security software, training, and network policy tools. It is a discovery list—not a verified ranking, and it does not establish that every company is Australian-founded.
How to read this company list
The descriptions below reflect how Built In characterizes each company; they are not independent assessments of product quality, market share, or local operations. The source includes hiring references, but it does not provide a standardized comparison of open roles, qualifications, or locations. Use the list to identify areas of work, then check each employer’s own careers information for current openings.
Companies focused on services and security operations
CyberCX
Built In describes CyberCX as a provider of cybersecurity services to public- and private-sector organizations. Its listed work includes consulting, digital forensics, incident response, and security testing—areas relevant to candidates interested in client engagements and hands-on security services.
Dotsquares
Dotsquares is described as a technology company offering cybersecurity services such as cloud security, penetration testing, compliance assessments, and security-awareness training. The breadth of offerings points to varied service work rather than a single security specialty.
Huntress
Built In characterizes Huntress as a people-powered cybersecurity company with a Security Operations Center and continuous, AI-assisted threat protection. The article notes remote Australian roles, which may be useful to candidates looking beyond office-based positions; check the company’s careers page for current location and eligibility details.
Companies building security platforms and tools
CSC
Built In describes CSC as providing cybersecurity solutions for digital brands, compliance, and data. Its article says the company has more than 40 offices worldwide; that figure is Built In’s description, not an independently verified office count.
Secure Code Warrior
Secure Code Warrior is described as an upskilling platform offering hands-on education about software vulnerabilities and secure coding. It may interest readers drawn to developer education and helping software teams build security skills.

Built In characterizes Snyk as a developer security platform covering custom code, open-source dependencies, and cloud infrastructure. Its stated focus sits at the intersection of application security and software development workflows.
Rank #3
Cloudflare
Cloudflare’s products are described as protecting internet applications and networks. The article groups it among cybersecurity companies, while its stated scope also encompasses broader internet infrastructure and application protection.
Rubrik
Built In describes Rubrik’s focus as zero-trust data security, including data integrity, risk monitoring, and restoration after infrastructure compromise. The article says Rubrik has offices in Sydney and Melbourne; it does not establish which roles are currently available at those locations.
Datadog
Datadog is described as a SaaS monitoring platform covering infrastructure performance, user activity, and logs, with dashboards. This is a monitoring-centered offering rather than a description of a dedicated incident-response service.

Zscaler
Built In describes Zscaler as offering zero-trust security capabilities for users, data, applications, and devices. The article also mentions Australian government and enterprise customers, along with data centers in Sydney, Melbourne, Canberra, and Perth; those details are the article’s claims, not a measure of current hiring or company presence beyond what it states.
Best Value
Tufin
Tufin is described as providing network security policy management. Built In identifies a Sydney office and says its SecureTrack+ product provides visibility and control for hybrid-cloud networks.

The companies represent different kinds of security work, so start with the work you want to do rather than treating the list as a league table.
- Client-facing services: Explore CyberCX and Dotsquares for the consulting, testing, forensics, incident response, compliance, and training work described by Built In.
- Security operations: Huntress is the entry in this list specifically described as having a Security Operations Center and continuous threat protection.
- Secure software and developer enablement: Secure Code Warrior and Snyk are the clearest matches for secure-coding education and developer security platforms.
- Applications, data, networks, and infrastructure: Cloudflare, Rubrik, Datadog, Zscaler, Tufin, and CSC cover different combinations of application protection, data security, monitoring, zero trust, network policy, and digital-brand security in Built In’s descriptions.
Before applying, confirm the role’s responsibilities, required experience, work location, and employment eligibility directly with the company. The list does not supply salaries, job-market statistics, or a consistent account of each employer’s Australian hiring footprint.
Australian cybersecurity guidance
For context beyond employer research, the Australian Cyber Security Centre (ACSC) identifies itself as the Australian Government’s technical authority on cyber security. It publishes advice and tools for government, large organisations and critical infrastructure, small and medium businesses, and individuals. Its website lists resources including a Personal cyber security handbook and a Small business cyber security handbook. These public resources provide local guidance; they do not independently verify Built In’s company descriptions.
