sovereign-shield and intentshield
These are complementary tools: Sovereign-Shield provides broad security infrastructure (injection firewall, DDoS protection, adaptive filtering) while IntentShield specifically audits agent intent pre-execution, making them designed to be layered together in a defense-in-depth authorization strategy.
About sovereign-shield
mattijsmoens/sovereign-shield
AI security framework: tamper-proof action auditing, prompt injection firewall, ethical guardrails, DDoS protection, and self-improving adaptive filters. Zero dependencies, deterministic, hash-sealed integrity verification. Patent Pending.
Implements a deterministic-first architecture where input flows through 12+ sequential checks (invisible character stripping, homoglyph folding, entropy detection, 200+ keyword matching) before optional LLM verification, with the LLM's own response validated against CoreSafety and Conscience modules. Features a self-learning AdaptiveShield engine trained on reported false negatives and a safe baseline of 11,954+ common words across 15 languages to minimize false positives. Integrity-protected via cryptographic hash locks on core security modules, ships as a zero-dependency Python package targeting autonomous agents and untrusted input scenarios.
About intentshield
mattijsmoens/intentshield
Pre-execution intent verification for AI agents. Audits what your AI is about to do, not what it says. Zero dependencies, deterministic, hash-sealed.
Intercepts action payloads (shell commands, file operations, API calls) before execution using two deterministic safety layers—CoreSafety with hash-sealed immutable rules and Conscience with regex-based behavioral detection—eliminating LLM calls from the security path. Provides optional human-in-the-loop approval and SIEM-compatible structured logging, with per-action type auditing (SHELL_EXEC, FILE_WRITE, BROWSE, ANSWER) returning deterministic pass/block decisions tied to specific rule violations.
