Dimension	Abnormal Security	Proofpoint Core Email Protection
Pricing and trial	Inbound Email Security Requires quote · custom quote Inbound Email Security is the single retained core offer. Account takeover protection, AI Security Mailbox, Email Productivity, Security Posture Management, Misdirected Email Prevention, and other platform products require separate commercial scoping. AWS Marketplace is an alternative private-offer route, not a second plan. Abnormal Cloud Email Security on AWS Marketplace: AWS Marketplace can transact a private offer containing an Inbound Email Security dimension. This route does not create another core plan or establish a reliable public price. Full profile	Core Email Protection Requires quote · custom quote Proofpoint presents Core Email Protection as the email-security foundation and sells it by quote. User count and single- or multi-year contract term can affect budgetary pricing, and Proofpoint notes possible consumption exceptions without publishing the metering unit or rate. API and SEG are deployment choices within Core, not separate plans. AWS Marketplace separately lists a 500-user Core (P0) email security package at USD 96,000 for a 12-month contract; that route is not used to set the direct-plan starting price. Higher Collaboration Security tiers, Essentials, 365 Total Protection, DLP, archiving, continuity, account-takeover products, and services have separate scope. Proofpoint Security on AWS Marketplace: An AWS Marketplace contract for 500 users of the Core (P0) email security package. It is a route-specific commercial state for Core, not a second Core plan or a direct-price proxy for other user quantities. Full profile

Rank	#1	#7
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.	86Delivers coordinated lifecycle threat protection using machine learning, computer vision, and global threat intelligence to dynamically block attacks.
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accuracy	84Detection 360 for submitted misses and false positives indicates feedback for quality review, but the facts do not publish measured accuracy rates, so buyers should validate performance on their own mail flow.	82Nexus AI relationship graphs and language analysis identify internal phishing and lateral threats, with accuracy supported by historical learning during API onboarding.
BEC and identity protection	92Focuses heavily on identity and relationship signals, though full cloud account takeover protection is billed as a separate product.	84BEC, impersonation, lookalike-message, and email-focused account-takeover-signal detection are included in Core, while broader cloud-account investigation and remediation sit in separate Account Takeover Protection packaging.
Response operations	86Integrates automatic malicious-message remediation with REST APIs for SIEM, SOAR, EDR/XDR, IAM, and ITSM.	85Supports abuse-mailbox automation and post-delivery message clawback, but standard core plans do not automatically package premium managed operations or external analyst services.
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.	83Accommodates API, gateway, or combined deployments, but API onboarding is tailored to Microsoft 365, while Google Workspace and Exchange require deployment-specific validation.
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.	73Integrates threat forensics and coordinates response across tools, but governance features such as compliance archiving, encryption, and data loss prevention require separate add-on licenses.
Support and total cost	50Total cost is unpredictable due to undisclosed pricing, unstated commitment terms, and unverified migration or professional services fees.	54Licensing is sales-quoted by user count and contract term with no permanent free plan or public Core trial, and managed operations, implementation, training, and premium support are not automatic inclusions, so total cost stays quote-dependent.
