CST VerdictShort answer
Startup and SMB security teams protecting Microsoft 365 will benefit most from Attic M365 FREE because it stops AiTM phishing attacks that bypass MFA, the attack class traditional email filters miss entirely. The tool deploys in five minutes with no payment required, making it immediately useful for resource-constrained teams, and its real-time detection of fake login pages covers both NIST PR.AA and DE.CM functions simultaneously. Skip this if your organization needs protection beyond Microsoft 365 or runs a heterogeneous SaaS stack; Attic is deliberately focused on one platform and one threat vector. 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.
