Attic M365 FREE vs GoSecure Titan® Inbox Detection & Response (IDR): Side-by-Side Comparison (2026)

Attic M365 FREE

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.

GoSecure Titan® Inbox Detection & Response (IDR)

Mid-market and enterprise security teams drowning in user-reported phishing will cut investigation time from hours to minutes with GoSecure Titan® IDR, where a human analyst reviews every flagged email within your SLA instead of relying on pure automation. The combination of AI triage plus mandatory human verification hits NIST DE.AE and RS.AN hard, turning your inbox into a forensics asset that actually surfaces IOCs and POCs for threat intelligence. Skip this if your team lacks email integration bandwidth or you're looking for a tool that also handles post-breach incident response; Titan owns the reporting phase but stops at the inbox door.
