About Cytix

  • Software never stops changing. Teams ship new code every day, through tickets, pull requests, releases, and increasingly with AI in the mix, but the way security keeps up with all that change hasn't really moved on.

  • That's the problem we're solving. Cytix helps organisations understand which software changes actually matter, what should happen next, and how to prove the right call was made. Security understood, in other words.

    We're a small team with big plans, so every person we hire genuinely shapes what Cytix becomes. That's why we're upfront about our five values: we interview for all of them, and they matter to us more than a perfect CV. They're things you do, not things you are, so have a read and see if they sound like you.

     

    Make the first move. When the goal is clear but the path isn't, you get moving rather than waiting for perfect instructions. If you're blocked, you make a sensible call, say what you're assuming, and explain how you'd course-correct. We'd rather you act and be slightly wrong than sit still.

     

    Find the smarter path. You ask why before how. You dig into what the real problem is instead of just building what the spec says, and you're happy to question 'that's how it's always been done' when the reason behind it has gone stale.

     

    See it through. When something's yours, it lands. No loose ends, no surprises for whoever picks it up next. You keep people posted when things change, and if something falls between roles, you catch it.

     

    Raise the bar. You do the best job possible in the time you've got, whether that's a day or a month. Sometimes that means deep craft; sometimes the smartest move is quick and scrappy. It's about good judgement, and we hold each other to it without blame or politics.

     

    Play to win. You care about the mission but don't take yourself too seriously. You say 'I' when things go wrong and 'we' when they go right, trust teammates to do things their own way, and bring a bit of humour when the pressure's on.

    Sound like you on a normal working day? We'd love to meet you.

What We Do

Cytix is the first truly continuous security testing platform, focused on identifying change and using it to intelligently determine when to test. Whether it’s a developer making a pull request, threat intelligence about a new vulnerability, or a new server being deployed, we take feeds of data from across your technology stack and use this as telemetry to determine what has changed and what actions need to be taken to assess the impact that this has had on security. Simply connect us to your existing workflows through our list of pre-built integrations or leverage the suite of native tools within our platform. We bridge the gap between automation and manual testing by identifying what actions are needed at any time and carrying them out as a sequence of tasks. Through this, we are able to minimise the time between vulnerabilities being introduced and being identified, and provide the information you need in order to resolve them as efficiently as possible. We support applications, APIs, cloud-native services, and traditional infrastructure, providing you with a centralised platform from which to build a continuous security testing programme. We are CREST-accredited and our product can either be used to drive an internal security testing programme, or as a fully managed service. Watch as your entire security testing programme runs automatically.
