About Security International Group
Security International Group (SIG) is an open-source organization building cyber defense infrastructure for Linux environments. We create freely available tools that automate compliance, enforce hardening baselines, and deliver actionable security telemetry to enterprise and federal organizations.
Mission
Make enterprise-grade Linux hardening accessible to every defender, from individual administrators to federal agencies.
Approach
Automate what can be automated. Open source what should be open. Build for auditability, not lock-in.
Community
Built by practitioners for practitioners. Our tools are shaped by real-world federal and enterprise deployments.
Core Principles
Security through transparency, all code is open and auditable.
No proprietary lock-in, standard formats, open standards.
Federal-grade by default, DISA STIG, CIS, and NIST 800-53 first.
Community-driven, shaped by the people who deploy it.
