We are the team behind S4E - Security For Everyone.

We believe a 5-person startup and a 5,000-employee enterprise face the same attackers, but only one can afford a security team. We started S4E in 2021 to close that gap. Security was expensive, slow, and built for experts - we decided to change that.

Today, S4E.io is a Continuous AI-Based Security Operations platform with 14,000+ security checks, AI-powered scanning, and automated remediation - making cybersecurity understandable, accessible, and manageable for organizations of every size.

We actively develop and maintain open source security tools and believe in giving back to the community that powers the internet.
