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."

Questions
Everything you need to know about building custom software with us
SIEM (Security Information and Event Management) is a security platform that collects, centralises, and analyses log and event data from across your entire IT environment, including cloud systems, on-premises infrastructure, networks, and endpoints. It correlates this data in real time to detect threats, anomalies, and suspicious activity that individual systems would miss on their own, and generates alerts so your security team can respond quickly.
Modern cyber threats are sophisticated and often spread quietly across multiple systems before causing visible damage. SIEM gives you unified visibility across your entire environment so threats are detected and responded to early, compliance requirements are met, and your security team has the context they need to investigate and act. Without it, threats can go undetected for days, weeks, or longer.
We are platform-agnostic, meaning we recommend the SIEM solution that best fits your specific environment, compliance requirements, budget, and internal capabilities rather than defaulting to a single product. We work with leading security vendors and assess your needs before making a recommendation.
SIEM platforms generate detailed logs and reports of security events across your environment, which is a requirement of many Australian industry regulations and the Australian Privacy Act. We configure your SIEM to produce the compliance reporting your business needs and ensure your monitoring environment meets relevant regulatory standards.
Yes. Modern SIEM platforms collect and correlate data from cloud environments including AWS, Azure, and Google Cloud, as well as on-premises infrastructure, networks, and endpoints. We configure your SIEM to provide unified visibility across your entire IT estate regardless of where systems are hosted.
Yes. We provide ongoing monitoring, tuning, and management of your SIEM environment to keep detection rules current, reduce false positives, and ensure your security monitoring keeps pace with changes to your infrastructure and the evolving threat landscape.
