Trellix Email and Collaboration Security Emerges as a Market Leader

By Joel Boyd · September 25, 2025

Executive summary

With the rise of AI use amongst attackers and growth in phishing-as-a-service platforms lowering the cost and effort to successfully run social engineering campaigns, human-risk management and an ability to protect a users’ entire workspace environment is front and center for many of our customers. But it’s more than just a conversation about email security. In recent years, enterprise chat tools have become second nature to most workers, sometimes even replacing email as the primary communication tool, and the sheer volume of file sharing and storage have significantly increased as well. And though protecting these channels is critical and security awareness training continues to prove invaluable, there’s no getting around the time-honored wisdom that users simply make mistakes, especially under the pressure of social engineering. This leads many organizations to hunt out solutions that not only include protection for email security and chat functions, but also ways of effectively scanning incoming files and hidden URLs at scale, with an added layer of data security and DLP to prevent data leakage and exfiltration.

At Trellix, we deliver all of these components as part of our email and collaboration solution for our customers as a part of their multivendor security strategy, or more commonly, as part of our larger Trellix Security Platform. We’re extremely proud and honored to receive industry recognition as a market leader in the recently published KuppingerCole Leadership Compass for Email Security that offers a comprehensive analysis of market options.

“Trellix, headquartered in the United States, was established in 2022, evolving from FireEye's legacy in email security. The company offers a robust email security solution designed to address contemporary cyber threats, underscoring its commitment to addressing email and collaboration security as the cornerstone of broader workspace security.”

Precision matters: Elite detection with minimal false positives

In the face of AI-powered attacks and sophisticated phishing campaigns, detection efficacy is understandably the most important piece of the human-risk management equation. At Trellix, we’ve been successfully catching these attacks for years for some of the world’s top government agencies and Fortune 100 companies with a combination of contextual, sentiment analysis alongside meticulous impersonation checks. We appreciate KuppingerCole’s highlight that, “Trellix distinguishes itself through its pioneering use of AI-driven innovations and a strong emphasis on integrating threat intelligence, which harnesses insights from its tens of thousands of customers.” Over 40,000 customers in fact, spanning email, network, endpoint, and cloud solutions, giving us a wide breadth and understanding of multichannel attack samples and techniques modern attackers attempt to utilize.

But, where Trellix really shines is in our detection accuracy. Our team of engineers is constantly fine-turning and refining our detection engines to mitigate new attacker strategies. We don’t release a new engine or update until it’s gone through an extensive stress-test capable of delivering less than one false positive per million detections. At a time when security budget growth is slowing while the prevalence of threats increases, it’s more important than ever that analyst cycles are optimized.

Don’t pick and choose: Precise file and URL analysis at scale

Part of Trellix’s winning combination lies in our Intelligent Virtual Execution (IVX) engine. IVX, a custom hypervisor designed specifically to ferret out obfuscated and evasive threats at scale across collaboration and enterprise applications, is capable of running across 200 execution environments at a rate of over 2,000 simultaneous executions and is the workhorse of the Trellix Security Platform. Not only is it responsible for analyzing any files or URLs that come in via email, it’s how Trellix is able to extend our threat hunting and investigation to any enterprise application within our customers’ environments that interacts with files or embedded URLs.

For many organizations, legacy tools attempting to handle this issue fall short. Traditional sandbox technology lacks the technology and architecture to recreate environments that truly resemble current real-world situations and human interaction. However, IVX performs multiflow analysis to break down and fully understand the full context of multistage attacks including the possibility of secondary or combination techniques across multiple phases to precisely identify malicious files, URLs, and zero-days.

Drive resilience with awareness and data security

Still, despite an organization’s detection capabilities, their employees’ human nature will continue to be a soft spot in their security posture. To help improve employee awareness and speed security teams’ ability to drive awareness, Trellix recently added our own optional phishing simulator module to our email security solution. Using AI and real-world, timely insights from Trellix’s Advanced Research Center, the Trellix Phishing Simulator dramatically reduces the level of creativity and effort security teams need to invest to distribute high-impact, relevant phishing tests to their workforce.

Additionally, added security from Trellix Data Security natively integrates with our email solutions to provide an additional layer of DLP to communications and file sharing. All in an effort to help maintain proper corporate governance and mitigate risk from user mistakes and aggressive social engineering tactics.

Curious what others are seeing?

As the threat landscape continues to evolve with increasingly sophisticated AI-powered attacks and the expanding attack surface of modern collaboration environments, organizations need more than point solutions—they need comprehensive protection that adapts as quickly as threats do. Through our unique combination of elite detection accuracy, scalable file and URL analysis, integrated human risk management, and intelligence gathered from over 40,000 customers worldwide, Trellix Email and Collaboration Security delivers.

The recognition from KuppingerCole as a market leader validates what our customers already know: when facing today's complex threat environment, precision and integration matter more than ever. With security budgets under pressure and analyst time at a premium, organizations can't afford solutions that generate noise or leave gaps in their defenses. Our commitment to delivering less than one false positive per million detections, combined with IVX's ability to analyze threats across execution environments at scale, ensures that security teams can focus less on managing their email systems and more on proactive threat prevention and discovery.

Trellix Email and Collaboration can be deployed on-premises and in the cloud, as a SEG, second hop, or via API in an ICES role, ensuring your organization maintains the flexibility it needs to keep moving. Whether deployed as part of a multivendor strategy or integrated within the broader Trellix Security Platform, our email and collaboration security solution positions organizations to not just defend against today's threats, but to stay ahead of tomorrow's challenges with confidence and resilience.
