We're a small security firm based in the UK. Our team comes from the capture-the-flag scene, and we started V1olet to do that kind of work for organisations that can't hire a security team of their own.

Attack and defence in one team

In security, the red team attacks and the blue team defends. Most firms do one or the other. We do both, and each side makes the other better: defenders who know how attacks actually work, and testers who know what defenders can see.

Capture the flag

CTF competitions give teams a few days to solve security challenges: breaking web applications, exploiting binaries, reverse engineering, cryptography, forensics and open-source intelligence. You're up against teams from all over the world, and the clock.

Our team, v1olet, has played international Jeopardy-style events since August 2026. Follow it at ctf.v1olet.xyz and on CTFtime.

What you can expect from us

  • The same people throughout

    A consultant for reviews, the same testers from scoping to retest, and a named Blue Lead on every retainer.

  • Plain reports

    Written for the people who have to act on them: management first, then the technical detail, in the order we'd fix things.

  • Discretion

    We only access what the job needs, and return or delete your data when we're done.
