Legal Industry From failing the audit to insurance-grade in 90 days
The Challenge A NSW law firm faced a failing security audit, looming cyber insurance renewal, and Law Society trust accounting obligations they could not evidence. Legacy antivirus, untested backups, and no detection capability left them exposed to the exact threats targeting legal practices: trust account fraud, business email compromise, and ransomware.
The Solution Extranet Systems deployed a fully managed security stack: EDR, 24/7 SOC, advanced email security, Microsoft 365 and endpoint backup, RMM patching, and independent penetration testing. Each control was mapped directly to an Essential Eight, ISO 27001, or Law Society requirement. No shelfware. No over-engineering.
The Outcome The firm uplifted to Essential Eight Maturity Level 2, closed their ISO 27001 control gaps, evidenced trust accounting compliance for the Law Society of NSW, and renewed cyber insurance at improved terms. Zero successful phishing or BEC incidents since go-live.
"We went from three disconnected tools to one unified system in 12 weeks. The team hasn't looked back, and neither have we."
Our Happy Clients
Hear from satisfied business owners and executives who've trusted Extranet Systems with their business challenges.
Extranet Systems provides very professional service on fulfilling our IT requirements. Having them on board really reduced a lot of our stress on looking after the IT infrastructure.
Working with Extranet Systems, their Software development, and integration with two of our other Software platforms went very smoothly, they were able to come back with something in no time.
We recently engaged Extranet Systems to help implement AI into our business. They were very professional and had constant communication throughout the entire project.
Extranet gave us a level of integration we didn't think was possible. Night and day difference. Thank you Extranet.
A pentest proves where you stood. PentestOps proves where you stand.
PentestOps is our Australian-built platform for continuous penetration testing: it discovers your attack surface, tests it continuously, validates the attack paths through it and safely exploits findings to show the impact is real. Human-led testing and continuous validation do different jobs, and most teams need both.

Meeting compliance requirements is a starting point, not a finish line. We take a security-first approach that uncovers what a real attacker would actually find across your network, systems, applications, and physical environment.
Every Attack Surface Tested
Cyber threats are always evolving, and your testing should too. We simulate real-world attack scenarios across every layer of your environment.

Questions
Everything you need to know about building custom software with us
Penetration testing involves simulating real cyberattacks against your systems, networks, and physical environment to identify vulnerabilities before real attackers can exploit them. It goes beyond automated scanning by using expert testers who think and act like attackers, uncovering the full attack path and the potential business impact of each weakness found.
We offer external penetration testing, internal penetration testing, wireless security testing, physical security testing, hardware and IoT testing, vehicle systems testing, and custom network protocol testing. Each engagement is tailored to your specific environment, threat model, and organisational goals.
External penetration testing assesses whether your perimeter defences can withstand attacks from outside your network. Internal penetration testing evaluates what an attacker could achieve once inside, assessing how quickly an internal threat could spread and compromise critical systems.
Yes. Attackers use any method available, including physical access. We test building security controls such as locks, badge readers, and access points, and assess your employees' resilience against social engineering techniques like tailgating and badge cloning.
You receive a detailed report with severity-ranked findings, a clear explanation of the attack path for each vulnerability identified, and expert recommendations for remediation. This goes well beyond a simple pass or fail, giving your IT team the specific insights needed to strengthen your defences.
Cyber threats evolve constantly, and your testing should keep pace. The right frequency depends on your industry, risk profile, and how often your systems or infrastructure change. We can advise on an appropriate testing schedule during your initial consultation.
Why Businesses Invest in Penetration Testing
Real vulnerabilities found. Real fixes recommended. Real confidence gained.
A process built around you, not the other way around
We don't disappear after kickoff and resurface six months later with a finished product. Every stage is collaborative, transparent, and designed to keep you in control.
External Penetration Testing
Simulate real-world attacks against your perimeter defences to expose weaknesses before attackers find them.
Internal Penetration Testing
Assess how fast an internal threat could spread and compromise systems across your entire environment.
Wireless Security Testing
Uncover how wireless connections could expose internal networks believed to be secure and isolated.
Physical Security Testing
Test building access, badge readers, locks, and employee resilience against social engineering and tailgating.
Hardware and IoT Testing
Security testing for IoT devices, embedded systems, firmware, medical devices, and industrial equipment.
Custom Protocol and Vehicle Systems Testing
Specialised testing for automotive systems, CANBUS, autonomous vessels, aircraft, and custom network protocols.
The Extranet Penetration Testing Advantage
We provide customised security testing across a broader range of environments than standard pen testing providers, from cloud and wireless through to IoT devices and physical security.
