Proofpoint Email Protection
Industry-leading enterprise email security with TAP, CLEAR, and Sigma threat graph
Proofpoint is consistently ranked a Leader in Gartner Email Security Magic Quadrant evaluations, with one of the largest dedicated email threat-research teams in the industry. The Sigma platform correlates telemetry across email, identity, and supplier relationships, surfacing BEC, vendor email compromise, and supply-chain attacks that other vendors miss. For UAE enterprises, banks, and regulated industries that need top-tier enterprise email protection with deep BEC visibility, Proofpoint is the gold standard.
Enterprise email security with deep BEC and supply chain telemetry
Proofpoint Email Protection (the MX-mode gateway) is augmented by Targeted Attack Protection (TAP) for URL and attachment defense, NexusAI for ML-based BEC and impersonation detection, and Closed-Loop Email Analysis and Response (CLEAR) for user-reported phish triage. The Sigma platform unifies email, identity, data, and supplier signals into one threat graph.
Proofpoint Aegis is the newer combined platform combining people-centric threat protection with adaptive controls based on user risk, while Proofpoint Sigma extends data loss prevention and insider threat management onto the same operational model.

- CLEAR: user-reported phish auto-triage with one-click clawback
- Sigma platform: email plus identity plus data plus supplier signals correlated
Proofpoint Core Email Protection / TAP / Prime Highlights
The gold standard for enterprise email. 3 trillion emails analysed. The deepest threat intelligence on the planet.
Proofpoint protects 87 of the Fortune 100 companies and processes over 3 trillion emails per year, making its Nexus AI threat intelligence engine the most battle-hardened in the industry. Its people-centric approach, powered by the Very Attacked People (VAP) concept, ensures the highest-risk individuals receive the most protection. Named a Leader in the 2025 Gartner Magic Quadrant for Email Security.

The most mature AI threat intelligence engine in email security
Nexus AI is powered by data from over 3 trillion emails analysed annually across Proofpoint's global customer base. It combines language models, relationship graphs, machine learning, and computer vision to stop BEC, account takeovers, QR code phishing, impersonation, and lateral phishing with unmatched accuracy.
Identify and protect your highest-risk individuals automatically
Proofpoint's VAP dashboard identifies which employees are most targeted by threat actors, not just by volume of threats, but by sophistication and potential impact. Security teams can apply adaptive controls, targeted training, and additional layers of protection specifically to the individuals attackers are most interested in.
Advanced threat protection: sandbox, URL defence, and attachment analysis
TAP combines static sandbox analysis, dynamic detonation, bare-metal execution, and analyst-assisted analysis for the most sophisticated threats. Predictive sandboxing is a Proofpoint patent, analysing files before delivery to catch zero-days and polymorphic payloads that traditional AV systematically misses. URL rewriting provides click-time protection.
Detect compromised vendor and supplier accounts: even before they email you
Proofpoint Supplier Threat Protection combines AI/ML behavioural analysis with threat intelligence gathered across its entire ecosystem to detect compromised third-party accounts, even accounts that have not yet sent malicious messages to your organisation. Early warning of supply chain compromise gives you time to respond proactively.
AI detects compromised credentials and persistent attacker access
TAP Account Takeover correlates threat intelligence with AI, ML, and behavioural analytics across the entire email attack chain. A simple password reset is not enough: attackers with persistent access to email accounts can manipulate third-party apps. TAP ATO provides automated remediation that removes persistent access, not just credentials.
Unified platform consolidating six security tools into one console
Proofpoint Prime Threat Protection (launched April 2025) consolidates Email Protection, TAP, Adaptive Email Security, TRAP, EFD, and Domain Discover into a single console, ending the fragmented multi-portal experience. Prime is also designed for agentic AI workflows, with native hooks for auto-investigation, abuse mailbox triage, and collaborative forensics.
Real-time user coaching: contextual warnings at the point of risk
Proofpoint Email Warning Tags display contextual risk indicators directly within the user's email interface, flagging external senders, suspicious domains, newly registered domains, and DMARC issues. This turns every potentially dangerous email into a micro-training moment that reduces phishing susceptibility over time.
Context-aware data loss prevention across email and cloud platforms
Proofpoint DLP applies context-aware filtering and policy-driven controls to prevent sensitive information leaving the organisation via email or cloud platforms. Insider risk detection identifies unusual data movement patterns, flagging departing employee data exfiltration, accidental external sharing, and policy violations before they become breaches.
Proofpoint dominates the Fortune 100 for a reason: the deepest threat intelligence from the largest enterprise deployment base, the most mature TAP sandbox (including a patented predictive sandboxing capability), and a people-centric approach that protects the actual humans attackers target rather than just filtering generic threats. For large, complex enterprises with sophisticated threat profiles, Proofpoint remains the reference standard.

Frequently asked
Proofpoint Email Protection questions we hear from UAE buyers
How does Proofpoint compare to Sophos Email or Mimecast?
Proofpoint typically leads on enterprise BEC, supplier compromise, and the Sigma platform breadth, with higher TCO. Sophos Email is the better fit for UAE mid-market customers running Sophos elsewhere. Mimecast wins on email continuity and archiving depth. We size all three for shortlist customers.
