How to choose
These conclusions apply to this subcategory and the buyer conditions shown here. They do not make one product universally better.
Cloudflare Email Security
Consider when
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
Check before choosing
Buyers that require transparent public amounts, month-to-month purchasing, or a permanent free protection edition
Organizations expecting Advantage to include API or mixed deployment, email isolation, outbound DLP, one-year retention, SOC APIs, or employee-account-compromise detection
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.

Seven standalone email editions are retained: five FortiMail Cloud Hosted editions and two FortiMail Cloud SaaS editions. Public numeric amounts, currency, payment timing, minimum contract commitment, renewal terms, and implementation fees are not stated. Annual or per-year licensing establishes the rate period only. Hosted Gateway editions and the SaaS Inbound edition start at 25 mailboxes or users; a separate minimum for SaaS Internal Email Security is not published. Appliance models, VM sizes, FortiGuard bundles, the Full Email Security Bundle, Workspace bundles, add-ons, managed-service SKUs, and marketplace routes are not duplicated as plans.
FortiMail hardware appliances: Five current customer-managed hardware models provide on-premises FortiMail deployment. Appliance capacity, hardware cost, and annual FortiGuard subscriptions vary by model and selected service bundle.
FortiMail virtual appliances: Six current VM sizes support private-cloud, public-cloud, and on-premises virtualization with perpetual licensing plus annual subscriptions or full subscription licensing.
FortiMail Secure Email Gateway on AWS Marketplace: AWS Marketplace supplies the FortiMail VM image and infrastructure route, while the FortiMail license remains an external BYOL purchase. AWS infrastructure charges are not FortiMail plan prices.
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
Organizations with on-premises, public-cloud, hosted, SaaS, or hybrid email environments
Security teams that need a configurable secure email gateway with granular policy, authentication, DLP, quarantine, and reporting controls
Microsoft 365 and Google Workspace teams that need gateway, API, semi-inline, or mail-flow protection
Not for
Buyers that require transparent public amounts, month-to-month purchasing, or a permanent free protection edition
Organizations expecting Advantage to include API or mixed deployment, email isolation, outbound DLP, one-year retention, SOC APIs, or employee-account-compromise detection
Google Workspace or non-Microsoft buyers requiring the package-bound outbound DLP workflow, which is documented for Microsoft 365 only
Buyers that require transparent public numeric pricing or self-service monthly purchasing
Teams expecting the same capabilities, administration, and service coverage across every FortiMail deployment form
Buyers expecting Cloud API scanning, sandboxing, image analysis, continuity, or advanced MSSP administration in every base license
Machine learning, large language models, heuristics, optical analysis, reputation, threat intelligence, and sandbox analysis
SPF, DKIM, DMARC, sender alignment, impersonation analysis, and domain reporting
Cons
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.
Numeric price, currency, payment timing, minimum commitment, renewal terms, and implementation fees are not public.
Annual subscription and per-year rates do not establish a one-year minimum contract.
The selected appliance or VM model and FortiGuard service bundle materially affect throughput, domains, mailboxes, storage, and advanced protection.

Threat protection efficacy
87Utilizes multi-layered AI, expert rules, and active threat intelligence, though the platform's overall threat mitigation scope is optimized on the Enterprise plans.
80Utilizes threat intelligence from FortiGuard, but overall efficacy depends heavily on whether the buyer licenses basic filtering or premium sandboxing bundles.
Detection accuracy
83Uses Email Detection Fingerprint campaign analysis and behavioral patterns to minimize false positives, with PhishGuard adding manual analyst verification at the top tier.
78Balances machine learning, heuristics, and reputation checks, but avoiding false positives in classic environments relies on ongoing manual policy tuning and expert sizing.
BEC and identity protection
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.
85SPF, DKIM, DMARC, sender alignment, impersonation analysis, domain reporting, BEC, and account-takeover controls directly address identity abuse, with impersonation analysis called out as a Premium hosted capability buyers must license when required.
Response operations
85Enables automated orchestration and CSV exports, while full SOC integration and targeted API retractions require an upgrade to the Enterprise plan.
81The platform includes quarantine, message tracking, reporting, REST API, syslog, FortiAnalyzer logging, and integration with FortiSOAR and FortiSIEM, which supports operational response work, although some workflows require separate entitlements or connected products.
Platform coverage and deployment
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.
91Accommodates diverse architectures by supporting hardware, VMs, hosted cloud, and SaaS, though administrative workflows differ considerably between models.
Governance and integrations
75Features regional processing options across four global locations, but limits the entry plan to 90 days of retention and exactly 2 API CASB integrations.
84Native Security Fabric membership with FortiSandbox, FortiSIEM, FortiSOAR, FortiAnalyzer, REST API, and syslog supports governance and monitoring pipelines, while connected product licenses remain separate purchases.
Support and total cost
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.
60Licensing is sales-quoted per mailbox or user per year or via appliance and subscription bundles with no public amounts, and specialist sizing plus separately entitled sandbox, advanced administration, or Fabric components can raise total cost and ownership effort.
These are the stored dimension rationales returned with each score. They explain the buyer conditions behind the gap without speculating about hidden model reasoning.
