Dimension	Cisco Secure Email Threat Defense	Cloudflare Email Security
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	Advantage Requires quote · per email user/inbox · custom quote · one-year commitment · organizations with fewer than 5,000 employees Enterprise Requires quote · per email user/inbox · custom quote · one-year commitment Enterprise + PhishGuard Requires quote · per email user/inbox · custom quote · one-year commitment Cloudflare publishes three current Email Security packages but no numeric price. The official matrix explicitly states an annual contract priced by the number of email users or inboxes, which establishes a one-year commitment and the priced unit but not payment timing, currency, minimum quantity, renewal behavior, or a rate denominator. Buyers must talk to Cloudflare for an amount. Cloudflare One solution packages are broader bundles and are retained only as a related route without duplicate Email Security offers. Cloudflare One SASE, SSE, or Zero Trust solution packages: Cloudflare offers broader solution packages that can combine Email Security with SASE or SSE services. They are separate bundled purchases, not additional Email Security editions, and no bundle amount or entitlement is duplicated here. Full profile
Best for	Microsoft 365 organizations adding journaling-based behavioral and identity-aware protection without an inline ETD gateway Organizations modernizing to a cloud-native inline gateway across Microsoft 365, Google Workspace, on-premises Exchange, or other mail servers Security teams prioritizing BEC, impersonation, account takeover, QR phishing, ransomware, and previously unseen social-engineering attacks	Mid-market organizations under the Advantage employee threshold that need strong inline, BCC, or journaling email protection without advanced API and SOC functions Enterprises using Microsoft 365, Google Workspace, other cloud email, or on-premises mail systems that need flexible deployment and advanced BEC, impersonation, link, attachment, and account-compromise protection Security operations teams that need message search, quarantine, retraction, API, orchestration, longer retention, outbound Microsoft 365 DLP, and regional processing options

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	AI, threat intelligence, expert rules, sender reputation, behavioral analysis, conversation context, and Email Detection Fingerprint campaign analysis Protection against phishing, BEC, impersonation, vendor fraud, compromised accounts, spam, spoofing, bulk mail, malware, malicious links, attachments, and QR-code attacks MX/Inline, API, BCC, journaling, and mixed deployment with provider-specific pre-delivery or post-delivery response options Message investigation, search, similar-email discovery, quarantine, bulk move, reclassification, reporting, CSV export, APIs, and orchestration Enterprise email link and attachment isolation, Microsoft 365 outbound DLP, targeted API retractions, and one-year detection retention
Cons	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.	No public package amount, currency, payment schedule, minimum quantity, renewal rule, cancellation term, implementation price, or services amount is stated. The contract is annual and priced by users or inboxes, so mailbox scope, shared or service inbox treatment, and final quantity rules require a quote. Advantage is limited to organizations with fewer than 5,000 employees and omits several advanced deployment, response, isolation, DLP, and integration functions.

Rank	#3	#4
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.	87Utilizes multi-layered AI, expert rules, and active threat intelligence, though the platform's overall threat mitigation scope is optimized on the Enterprise plans.
Detection accuracy	81Maintains high classification accuracy using retrospective verdicts and sender relationship analysis, though precise internal accuracy metrics are not publicly published.	83Uses Email Detection Fingerprint campaign analysis and behavioral patterns to minimize false positives, with PhishGuard adding manual analyst verification at the top tier.
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.	86BEC, impersonation, vendor fraud, and spoofing protections are core, and employee-account-compromise detection is available on Enterprise, aligning identity-centric fraud controls with higher editions.
Response operations	84Simplifies SOC workflows through out-of-the-box Cisco XDR casebook integrations and versatile REST APIs for automation.	85Enables automated orchestration and CSV exports, while full SOC integration and targeted API retractions require an upgrade to the Enterprise plan.
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.	80MX/inline, BCC, and journaling are included on Advantage for eligible organizations, with API and mixed deployment plus regional processing in the US, Germany, India, and Australia extending coverage on Enterprise tiers.
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.	75Features regional processing options across four global locations, but limits the entry plan to 90 days of retention and exactly 2 API CASB integrations.
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.	55Pricing is custom-quote only under a one-year user-or-inbox commitment with no public amount, currency, payment schedule, or minimum quantity, so total cost and support packaging remain opaque until a sales engagement and may rise materially when Enterprise or PhishGuard capabilities are required.
