S4E

Security For Everyone (S4E) is a continuous AI-based security operations platform that helps organizations discover, assess, and remediate security risks across their entire digital surface.

S4E combines automated vulnerability scanning, intelligent web crawling, and AI-driven analysis to deliver actionable security insights without requiring deep security expertise. From startups to enterprises, teams use S4E to stay ahead of threats with minimal manual effort.

What we do:

→ Automated vulnerability scanning across domains, IPs, and network infrastructure

→ AI-generated scans and actions that adapt to your unique attack surface

→ Web crawler with API discovery, PII detection, and endpoint enrichment

→ Actionable findings with severity scoring, status tracking, and one-click remediation

→ Comprehensive API for integration into existing workflows and CI/CD pipelines

Deployment flexibility:

S4E is available as a fully managed cloud platform (app.s4e.io) and as an on-premises solution for organizations with strict data residency, compliance, or air-gapped requirements.

For partners & MSSPs:

Our partner program enables managed security service providers to deliver continuous security operations to their customers through a multi-tenant platform with white-label capabilities, centralized management, and automated reporting.

Open source commitment:

We actively contribute to the security community through open source projects including scanner templates, action libraries, SDKs, and CLI tools — all available at github.com/s4e-io.

Headquartered in Turkey, S4E serves customers globally across finance, healthcare, technology, and government sectors.
