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. Mid-market and enterprise teams standardized on Microsoft environments need Idenprotect Go for its hardware-enforced browser isolation that actually blocks supply chain attacks through code injection protection and app repackaging detection. The combination of Secure Enclave/TEE controls, passwordless biometric MFA, and Entra ID integration means you're getting NIST PR.AA and PR.PS coverage without the complexity of bolting together five separate tools. Skip this if your workforce uses non-Windows devices heavily or you need macOS and Linux browser security at parity; Idenprotect Go is Microsoft-first by design.
