Dimension	Abnormal Security	Cisco Secure Email Threat Defense
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	ETD Essentials Requires quote · per user · custom quote ETD Advantage Requires quote · per user · custom quote ETD Essentials and ETD Advantage are the only retained core offers. Both use per-user pricing and require Cisco or partner-assisted purchasing. ETD Essentials can also be ordered for existing Cisco email-gateway customers, and it is available through the broader User Protection and Breach Protection Suites; those are acquisition routes rather than duplicate ETD plans. Subscription terms of 1, 3, and 5 years and several billing schedules are published, but no public amount is available and the wording does not establish a minimum commitment or cancellation policy. CSEMAIL-SEC-SUB for existing ESA or CES customers: Existing Cisco Secure Email Gateway or Cloud Gateway customers can order ETD Essentials as an add-on under CSEMAIL-SEC-SUB. This is an alternative ordering route for the same Essentials entitlement, not another ETD plan. Cisco User Protection Suite: Cisco User Protection Suite is a broader security bundle through which ETD Essentials is available. The suite and its other security products are not additional ETD editions, and no suite price is carried into this profile. Cisco Breach Protection Suite: Cisco Breach Protection Suite is a broader security bundle through which ETD Essentials is available. Its XDR and other security entitlements remain suite scope rather than ETD plan features. Full profile

Cons	Numeric price, priced unit, payment timing, commitment, renewal, and minimum purchase are not public. Account takeover containment, user-reported email automation, phishing training, posture management, graymail filtering, messaging security, and outbound data protection require separate scope confirmation. The core architecture depends on supported Microsoft 365 or Google Workspace APIs rather than an inline mail gateway.	No public numeric price, currency, minimum quantity, renewal rule, cancellation rule, or deterministic commitment state is available. The same Essentials and Advantage labels also appear in Cisco Secure Email Gateway licensing buyers must quote the ETD-SEC-SUB editions rather than assume gateway-bundle equivalence.

Rank	#1	#3
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.	86Integrates continuous Talos intelligence feeds with machine learning behavioral analysis to address newly emerging social-engineering techniques.
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.	81Maintains high classification accuracy using retrospective verdicts and sender relationship analysis, though precise internal accuracy metrics are not publicly published.
BEC and identity protection	92Focuses heavily on identity and relationship signals, though full cloud account takeover protection is billed as a separate product.	88Dedicated BEC, impersonation, and account-takeover analysis is reinforced by identity and relationship modeling, which helps teams target business-email and spoofing campaigns that pure signature controls often miss.
Response operations	86Integrates automatic malicious-message remediation with REST APIs for SIEM, SOAR, EDR/XDR, IAM, and ITSM.	84Simplifies SOC workflows through out-of-the-box Cisco XDR casebook integrations and versatile REST APIs for automation.
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.	81ETD Essentials deploys as Microsoft 365 journaling supplemental protection, and ETD Advantage extends cloud-native inline coverage to Microsoft 365, Google Workspace, Exchange on-premises, and other mail servers, so platform fit is edition-specific rather than universal.
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.	75Cisco XDR casebook integration, REST APIs, and four administration roles support governance hand-offs, while DLP needs extra Cisco Secure Access licensing on Advantage only, and domain protection plus awareness training remain outside core ETD.
Support and total cost	50Total cost is unpredictable due to undisclosed pricing, unstated commitment terms, and unverified migration or professional services fees.	57Cisco support is included for the product and sales-assisted free trials are offered, yet the absence of any public numeric per-user amount, currency, minimum quantity, or cancellation rule forces full TCO discovery through custom quote.
