Context	Security & Privacy / Email Security Software	Security & Privacy / Email Security Software
Threat protection efficacy	89The product combines behavioral baselines with identity, content, relationship, and reputation signals to address multiple inbound threat types, which supports broad threat coverage for cloud email security.	85Combines pre-delivery gateway screening and post-delivery API defenses to block complex threats, though direct efficacy metrics must be verified independently.
Detection accuracy	84Detection 360 for submitted misses and false positives indicates feedback for quality review, but the facts do not publish measured accuracy rates, so buyers should validate performance on their own mail flow.	82The detection stack includes behavioral AI, relationship graphing, natural-language analysis, anomaly detection, URL analysis, and attachment sandboxing, which suggests multiple detection signals are available, but the facts do not provide measured accuracy results or validated false-positive and false-negative rates.
BEC and identity protection	92Focuses heavily on identity and relationship signals, though full cloud account takeover protection is billed as a separate product.	90BEC, impersonation, account-takeover, sender-authentication, and DMARC controls together with relationship graphing target identity and trust abuse in email, giving strong alignment for buyers whose primary risk is executive fraud and compromised internal senders.
Response operations	86Integrates automatic malicious-message remediation with REST APIs for SIEM, SOAR, EDR/XDR, IAM, and ITSM.	88Supports deep threat hunting and integrations with external tools using REST APIs, syslog, SIEM, SOAR, and XDR workflows.
Platform coverage and deployment	88Documented API deployment for both Microsoft 365 and Google Workspace without mail-flow rerouting, plus fit for multi-tenant and acquisition-heavy administration, supports cloud-centric rollouts while excluding unsupported on-premises-only estates.	79Supports flexible API and MX-record deployment, but console integration is limited as the unified console does not yet support Google Workspace tenants.
Governance and integrations	81REST API hooks for SIEM, SOAR, EDR/XDR, IAM, and ITSM allow security and IT workflows to consume detections and drive response, with integration depth and bidirectional reliability left to buyer validation.	82Includes email encryption and outbound DLP, but requires the Premium Plus edition for cloud archiving, e-discovery, and legal hold.
Support and total cost	50Total cost is unpredictable due to undisclosed pricing, unstated commitment terms, and unverified migration or professional services fees.	62Twenty-four-seven support and per-seat licensing with a one-to-one user ratio are clear, yet the lack of public prices and the need to purchase Premium or Premium Plus for backup, archiving, and training leave total cost and commercial terms dependent on a custom quote.
