Dimension	Cisco Secure Email Threat Defense	Proofpoint Core Email Protection
Pricing and trial	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	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

Key features	ETD Essentials supplemental Microsoft 365 protection using journaling ETD Advantage cloud-native inline gateway and pre-delivery inspection Microsoft 365, Google Workspace, Exchange on-premises, and other mail-server coverage through the appropriate edition AI and ML detection using sender authentication, identity and relationship modeling, behavioral analytics, and Talos intelligence BEC, phishing, scam, impersonation, account-takeover, ransomware, QR-code, spam, graymail, file, and URL threat analysis	Coordinated pre-delivery, post-delivery, and click-time email protection Secure email gateway, API, and combined deployment support Nexus AI using language models, relationship graphs, machine learning, threat intelligence, and computer vision Sandboxing and analysis for malicious URLs and attachments BEC, phishing, impersonation, account-takeover-signal, spam, malware, QR-code, internal-mail, and direct-send detection

Rank	#3	#7
Context	Security & Privacy / Email Security Software	Security & Privacy / Email Security Software
Threat protection efficacy	86Integrates continuous Talos intelligence feeds with machine learning behavioral analysis to address newly emerging social-engineering techniques.	86Delivers coordinated lifecycle threat protection using machine learning, computer vision, and global threat intelligence to dynamically block attacks.
Detection accuracy	81Maintains high classification accuracy using retrospective verdicts and sender relationship analysis, though precise internal accuracy metrics are not publicly published.	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	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.	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	84Simplifies SOC workflows through out-of-the-box Cisco XDR casebook integrations and versatile REST APIs for automation.	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	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.	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	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.	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	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.	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.
