ID Agent Graphus vs SpamTitan for Office 365: Side-by-Side Comparison (2026)

Short answer

Security teams at startups and SMBs with Microsoft 365 or Google Workspace will find ID Agent Graphus worth the deployment because its TrustGraph AI catches social engineering attacks that signature-based filters routinely miss, and the one-click reporting loop turns employees into a second detection layer rather than just targets. The API-based deployment means no email rerouting complexity, which matters for resource-constrained teams. Skip this if your organization needs advanced post-breach forensics or recovery workflows; Graphus prioritizes detection and quarantine over incident response depth. SMB and mid-market teams running Microsoft 365 should pick SpamTitan for Office 365 if email hygiene is currently handled by M365's native defenses alone; its dual antivirus scanning and AI-powered phishing detection using Bayesian analysis will catch what Exchange does not. The sandboxing capability and outbound scanning directly address the NIST PR.DS requirement for data confidentiality without requiring a separate gateway appliance. Skip this if your organization needs unified threat management across email, web, and endpoints in a single console; SpamTitan is deliberately focused on email and will feel narrow compared to larger platforms.
