Intruder was founded in 2015 to help solve the information overload crisis in vulnerability management. Having worked both as an ethical hacker for tier one companies, and for blue teams defending critical national infrastructure, Founder Chris Wallis noticed that while vulnerability management tools were great at finding issues, they were less useful when it came to prioritizing them, tracking them, and timely alerting when problems arose. Quite simply - the most important issues were often getting lost in the noise.

Intruder's mission from day one has been to help divide the needles from the haystack, focusing on what matters, while ignoring the rest. Effective cyber security is about getting the basics right. Intruder helps you do that, saving time on the easy stuff, so you can focus on the rest.

Since its inception in 2015, Intruder has been awarded multiple accolades, was selected for GCHQ's Cyber Accelerator, and was included on Deloitte's Tech Fast 50 2023 list as the fastest-growing cybersecurity company in the UK. It is now proud to have over 3,000 happy customers all over the world.
