Gray Swan AI Security Suite vs Lumeus Secure Vibe Coding: Side-by-Side Comparison (2026)

Gray Swan AI Security Suite

Mid-market and enterprise security teams deploying internal LLMs and AI agents need Gray Swan AI Security Suite because it's the only platform that tests your models before attackers do, combining real-time input/output filtering with adversarial red-teaming at scale. The Arena competition model for vulnerability discovery and support for autonomous systems and MCP integrations mean you're securing the actual attack surface you're building, not hypothetical ones. Skip this if you're looking for a passive monitoring tool; Gray Swan requires active participation in security testing cycles, and the setup assumes your team has AI security expertise or is willing to build it.

Lumeus Secure Vibe Coding

Development teams shipping code through ChatGPT and other LLMs need to stop credentials and sensitive data from leaking into AI prompts, and Lumeus Secure Vibe Coding blocks that inline while mapping which AI tools developers are actually using. The tool covers ID.AM and PR.DS strongly with shadow AI discovery and MCP server data access mapping that most LLM guardrails skip entirely. Skip this if you need post-generation code scanning or SAST integration; Lumeus focuses on input/output filtering and access control, not vulnerability detection in the generated code itself.
