About us
Founded by a working cybersecurity professional
Sentryx was founded by a practising security engineer who still spends the week doing the work: running penetration tests, deploying detection and response tooling, standing up security operations, and sitting in the room when a business has to decide what to fix first.
That matters, because most security content is written by marketers. Everything we publish or sell has been used on a real engagement first. If a control is theatre, we say so. If a free fix will do, we will not sell you a tool.
