For over 20 years we've helped multinationals, governments and startups secure what matters. Technical audits, original research and specialised training, delivered by practitioners.
Four areas of practice, built on two decades of hands-on work with real adversaries and real systems.
End-to-end security for AI systems. LLM risk assessment, prompt-injection testing, model-abuse analysis and secure AI architecture design. We protect pipelines, data and models against misuse, leakage and adversarial attacks while keeping you aligned with emerging AI regulations.
For more than two decades multinationals, governments, startups and individuals have trusted us to assess the security of their infrastructures — networks, Wi-Fi, cloud — and software, including deep audits of cryptographic solutions and information-protection mechanisms.
Original research leading to proprietary, disruptive offensive and defensive techniques. Our work has been presented at Black Hat, Virus Bulletin, Hack In The Box, Ekoparty, RootedCON and other leading security conferences worldwide.
More than 1,400 professionals trained across 10,000+ hours of instruction, in person and online. Programmes range from foundational upskilling to advanced, hands-on workshops with real-world scenarios, tailored to the needs of each team.
