Email Threats Spike While Trend Micro Stumbles

Proofpoint provides a secure email gateway (SEG) and API options for Trend Micro customers who no longer wish to settle.

Overview

Organisations are rethinking Trend Micro

Trend Micro's email security portfolio includes Trend Vision One Email and Collaboration Security to protect against phishing attacks, ransomware, and BEC in Microsoft 365 environments. However, customers report unclear alerts, complex integration, and operational inefficiency. Also, Trend Micro was a Leader in the 2024 Gartner Magic Quadrant for Email Security Platforms, but only a Challenger in 2025.

Many are reassessing whether their Trend Micro email security tools are keeping pace with today’s evolving threat landscape.

Scale, Speed, and Coverage

Why customers choose Proofpoint over Trend Micro

Detection that keeps up with modern phishing and BEC

Trend Micro provides baseline phishing and malware protection, but users point to unclear alerts and extra steps for analysts to understand and act on suspicious activity. As attackers lean into payload-free fraud, delayed-detonation URLs, and supplier impersonation, this friction can slow response time and increase risk.

Proofpoint takes a fundamentally different approach. Multilayer AI-powered detection, dynamic URL and attachment analysis, and campaign-level correlation throughout the email lifecycle help security teams stop more sophisticated attacks and rapidly remediate threats at the inbox.

SOC workflows built for speed, not investigation loops

Trend Micro users report that deployments can involve a steep learning curve, challenges with integrating third-party tools, and advanced capabilities locked behind add-on modules. All these factors can slow adoption and increase administrative overhead.

Proofpoint streamlines email security operations with automated remediation, abuse-mailbox workflows, rich forensics, and flexible deployment options—including API-based protection behind M365 or full gateway replacement. Lean security teams see reduced manual work and faster time-to-value.

Complete email protection, not just inbound filtering

Trend Micro focuses mainly on inbound threat detection and sandbox analysis. However, modern email attacks increasingly require visibility beyond the perimeter, including post-delivery remediation, user behaviour insights, and outbound risk detection. Relying solely on traditional filtering can leave organisations reacting to threats only after they reach the inbox.

Proofpoint extends protection across the full email threat lifecycle—from advanced inbound detection to automated post-delivery response and outbound risk visibility through capabilities such as Adaptive Email DLP. This broader visibility helps security teams investigate incidents faster and secure sensitive data without added complexity.
