Cytix
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.
