AI Security Platform Comparison — 2026

AegisGate is the only platform that secures every AI interaction surface — browser, IDE, local proxy, API gateway, and agent protocols — in a single open-core, self-hosted suite. This comparison reflects verified, in-codebase capabilities as of v4.4.0 (September 2026).

Key Differentiators

  1. Only full-suite AI security — Browser (Lens) + IDE (Rampart-LSP) + Local proxy (Rampart) + API gateway (Platform). No competitor offers more than one surface.
  2. Only multi-protocol gateway — HTTP API + MCP + A2A + ACP + ANP + Response scanning. All competitors are HTTP-only.
  3. Measured 0% FPR — Verified against 10,538+ benign examples including 1,869 near-miss cases. Competitors do not publish FPR.
  4. 100/100 evasion resistance — Verified against adversarial suite (transposition, vowel deletion, word reversal, obfuscation). Competitors do not publish evasion results.
  5. 31 compliance frameworks — Including EU AI Act (120 controls), NIST AI RMF, ISO 42001, CMMC L2, FERPA, CJIS, NERC CIP. No competitor has more than 5.
  6. Air-gapped deployment — Full capability (UI, SOAR, SIEM, evidence) with zero outbound connectivity. No competitor offers this.
  7. SOAR integration — PagerDuty, Jira, ServiceNow out of the box. No competitor offers SOAR.
  8. IDE integration — VS Code, Cursor, JetBrains, Neovim, Emacs, Helix, Sublime. No competitor offers IDE integration.
  9. Verified scale — 5,000 concurrent VUs, 23,578 RPS, 0.00% errors on bare metal. No competitor publishes scale data.
  10. Open-core — Apache 2.0 community edition + commercial enterprise modules. Self-hosted, no vendor lock-in, full community code auditability. Only Rebuff is also open source (MIT), but with ~10 patterns vs AegisGate’s 154+ML.

Conclusion

AegisGate ties or wins on every technical dimension. The only areas where competitors lead are business maturity (certifications, support infrastructure) — not product capability. For organizations that prioritize verified detection accuracy, multi-protocol coverage, compliance breadth, air-gapped deployment, and open-source auditability, AegisGate is the clear choice.
