Cyber
Advisory
Defensive
G3’s Defensive Cyber team identifies and defines cyber risks presenting severe potential financial, regulatory, reputational or safety-related business impacts, and quantifies the possible costs incurred due to inaction. We produce costed actionable plans for resolution with defined owners, proposed technologies, and progress models to track remediation.
Offensive
We build a bespoke approach to battle-test your cyber security with our team of government-trained specialists, from penetration testing and dark net monitoring through to our proprietary G3 Advanced Threat Attack Simulations. We advise how to better defend the critical tasks on your networks.
Pre-Deal
Cyber Due Diligence
We help our clients identify key cyber risks; assess technical cyber defences; evaluate cyber maturity; and quantify remediation costs of their target companies. We work both outside-in and with access to management and information systems.
Maturity Assessments
We conduct best-in-class cyber security reviews for our clients. We design tailored cyber security frameworks based on industry standards and regulations; determine Board-level risk tolerance; define current and target maturity; and develop costed, time-bound implementation strategies.
Advanced Threat
Attack Simulations
Our offensive offering goes beyond a standard penetration to mimic the tactics, techniques and procedures used by nation-state capable threat actors. We identify the gaps in your defences; define how the threat actors will exploit those gaps; identify what digital assets will be stolen and destroyed; determine business impact; and quantify the risk.
