Dimension	Barracuda Email Protection	Proofpoint Core Email Protection
Pricing and trial	Advanced Requires quote · per seat · custom quote Premium Requires quote · per seat · custom quote Premium Plus Requires quote · per seat · custom quote Advanced, Premium, and Premium Plus are sold per seat through a sales-assisted process. Barracuda requires a one-to-one user-to-license ratio and publishes mailbox-count rules for Microsoft 365 and Google Workspace. No public numeric price, currency, payment schedule, minimum quantity, commitment duration, renewal term, or implementation amount is established for the three editions. AWS Marketplace is an alternative private-offer route for Advanced, not another plan. AWS Marketplace private offer: AWS Marketplace provides a private-offer acquisition route for the existing Advanced edition. It does not create another Barracuda Email Protection plan, and no route-specific numeric offer is retained. 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

Context	Security & Privacy / Email Security Software	Security & Privacy / Email Security Software
Threat protection efficacy	85Combines pre-delivery gateway screening and post-delivery API defenses to block complex threats, though direct efficacy metrics must be verified independently.	86Delivers coordinated lifecycle threat protection using machine learning, computer vision, and global threat intelligence to dynamically block attacks.
Detection accuracy	82The detection stack includes behavioral AI, relationship graphing, natural-language analysis, anomaly detection, URL analysis, and attachment sandboxing, which suggests multiple detection signals are available, but the facts do not provide measured accuracy results or validated false-positive and false-negative rates.	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	90BEC, impersonation, account-takeover, sender-authentication, and DMARC controls together with relationship graphing target identity and trust abuse in email, giving strong alignment for buyers whose primary risk is executive fraud and compromised internal senders.	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	88Supports deep threat hunting and integrations with external tools using REST APIs, syslog, SIEM, SOAR, and XDR workflows.	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	79Supports flexible API and MX-record deployment, but console integration is limited as the unified console does not yet support Google Workspace tenants.	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	82Includes email encryption and outbound DLP, but requires the Premium Plus edition for cloud archiving, e-discovery, and legal hold.	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	62Twenty-four-seven support and per-seat licensing with a one-to-one user ratio are clear, yet the lack of public prices and the need to purchase Premium or Premium Plus for backup, archiving, and training leave total cost and commercial terms dependent on a 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.
