We are cyber security specialists.

The ability to connect business systems to customers and suppliers via the cloud, browsers and smartphones has created huge opportunities. However, it has also brought unprecedented security risks – malware, phishing, ransomware and more. We specialise in protecting companies from cyber attacks. It’s all we do, every day, all over the world.

With highly satisfied clients in over 20 countries across 5 continents, we provide Penetration Testing, Vulnerability Assessments, Red Teaming, Incident Response, Malware Analysis, Asset Discovery, Source Code Review and Forensic Analysis. 

We have particularly deep expertise in multi-lingual Web Application and Network Infrastructure Penetration Testing.

We invest heavily in Research & Development, with each member of our technical team spending 25% of their time discovering, exploring and minimising new cyber threats; all of which is fed back into our client solutions and the wider cyber security community.

Our team has an established history of finding ‘zero days’ (previously unknown and unpatched software flaws) and uncovering security vulnerabilities in system software, web applications and browsers.

And we NEVER publicise who our clients are.
