Trellix Named a Major Player in the IDC MarketScape: Worldwide Modern Endpoint Security for Enterprises 2026 Vendor Assessment

By Sanjay Raja · November 12, 2026

Trellix has been named a Major Player in the IDC MarketScape: Worldwide Modern Endpoint Security for Enterprises 2026 Vendor Assessment.¹ For the organizations that rely on Trellix, and for the enterprise buyers evaluating their next endpoint platform, that position confirms something our customers already know: Trellix is built for the hardest environments in security, and it is built to run there as one platform rather than a collection of bolt-ons.

This post covers both halves of that statement. The first half is the endpoint platform itself, the part an endpoint assessment is designed to evaluate. The second half is what sits behind the endpoint: the capabilities managed from the same console that no endpoint assessment, by design, is built to measure. A buyer choosing an endpoint platform is also choosing how that platform works and can be extended within a security stack to add security value, and we think both halves belong in the same conversation.

Built for the environments that are hardest to secure

The enterprises with the most to lose rarely run a clean, cloud-only estate. A bank still has a trading floor on an older Windows build. A manufacturer has controllers on the plant floor that cannot be patched based on a vendor's schedule. A defense agency has networks that will never touch the public internet. Trellix supports a full spectrum of new and old operating systems, including Windows, MacOS, Linux, mobile devices (Android, iOS) and embedded/OT systems. In addition, it is built to operate in air-gapped environments and organizations focused on addressing data sovereignty requirements. 

The management console follows the same principle. It is offered as cloud, on-premises, or hybrid, so customers choose the deployment model that fits their rules rather than ours, and it integrates with the SIEM, SOAR, and ITSM tools an enterprise SOC already runs.

One console, four decades of endpoint heritage and threat research

Trellix brings together nearly four decades of endpoint management heritage with threat intelligence and incident-response expertise. The result is a comprehensive, integrated security suite designed to protect organizations from advanced cyber threats across all endpoints. Managed primarily through the Trellix ePolicy Orchestrator (ePO), the platform brings together several key defensive layers. These include Trellix Endpoint Security (ENS), which provides core prevention capabilities like anti-malware, firewall, and web security, and Trellix Endpoint Detection and Response with Forensics (EDRF), which monitors continuous endpoint activity to detect, investigate, and proactively hunt for stealthy threats. By consolidating these preventative, detective, and response tools into a single ecosystem, Trellix enables security teams to quickly reduce their attack surface and minimize response times to active incidents.

Trellix Wise for Private Cloud and the agentic SOC

Trellix Wise for Private Cloud provides an AI core for an agentic SOC supported by Trellix Endpoint Security that works across endpoint, network, email, and data telemetry. The analyst spends fewer hours stitching consoles together by hand and provides unified visibility, automated triage, event summarization, guided remediation, and rapid adaptation to emerging vulnerabilities, reducing analyst workload from hours to minutes.

What distinguishes the Trellix approach is where the AI runs, including the option to run in on-premises and air-gapped environments. For the regulated and sovereign environments described above, flexibility is the difference between an AI feature a customer can use and one they have to switch off.

Independently validated protection

Trellix Endpoint Security is tested by the independent labs that enterprise buyers rely on, across Windows, macOS, and OT. Recent results include an SE Labs 2025 AAA certification for Enterprise Endpoint on Windows, AV-TEST certification for Windows and macOS in March and April 2026, an Approved result in the AV-Comparatives Business Protection Test, and the AV-Comparatives 2026 Operational Technology Protection certification. Trellix also received 2025 recognition from Cyber Defense Magazine and Expert Insights for endpoint security.

The OT result deserves a second look, because it was earned under the conditions Trellix is built for. In the AV-Comparatives 2026 Operational Technology Protection Certification, Trellix Endpoint Security was tested on fully offline Windows 10 workstations with no cloud or internet connectivity. The test covered execution-based attacks using nation-state and industrial espionage tactics, an application update test that required telling malicious files apart from legitimate signed installers, and post-breach scenarios in which the attacker already had local system access. Trellix prevented 100% of the malicious scenarios without blocking a single legitimate update, with protection delivered by Adaptive Threat Protection and localized machine learning rather than a cloud lookup. For industrial and critical-infrastructure buyers, that is the result that matters.

Protection extends past detection. Ransomware recovery identifies and restores encrypted files hands-free, and rewinds associated file and registry changes without depending on OS-native shadow copies, which ransomware can itself compromise. Agent hardening includes kernel-level driver protection, anti-tampering, password-protected uninstall, and BYOVD protection. 

Beyond the endpoint: What an endpoint assessment does not measure

An endpoint assessment draws its boundary carefully. This IDC MarketScape study represents a vendor assessment of modern endpoint security offerings for enterprises in 2026, through the IDC MarketScape model.

“The defining shift in this iteration of the IDC MarketScape is that prevention has moved from aspiration to architecture. Attack volume, velocity, and variety now exceed what any security team can meet by hand, so enterprise endpoint platforms are increasingly expected to act autonomously and in real time, blocking threats at scale and bringing analysts in only for higher-order decisions. AI is doing much of that work, but no single method is sufficient; the strength lies in layering complementary engines,” says Mark Child, associate research director, security and trust at IDC. “Buyers should press on exactly that point. Ask not whether a vendor has AI, but where it is applied, what it decides without you, and how its road map answers frontier models that are accelerating vulnerability discovery. Then insist on testing in your own environment before committing, because a platform acting on your behalf at machine speed has to earn that trust on your estate, not the vendor.”

But an endpoint decision in a large, regulated, or industrial enterprise is rarely only an endpoint decision. It is a decision about what the console will manage in three years, whether the DLP policy will follow the data off the device, whether the sandbox will catch what the agent cannot, whether the systems you cannot patch will stay safe anyway, and whether anyone will tell you which campaign is coming before it arrives.

The capabilities below are the ones we hear about most from customers who came to Trellix for the endpoint and stayed for what was behind it. Each one is already managed through the same Trellix ePO console described above, which is the part that matters most.

Trellix Insights: Knowing which campaigns are coming for you

Threat intelligence often arrives as a feed of indicators that someone on your team must turn into a decision. Trellix Insights is built to make the decision for you, or at least to make it obvious.

Trellix Insights draws on risk intelligence gathered and refined from hundreds of millions of sensors and assessed by the Trellix Advanced Research Center. It then does something a feed cannot do. It looks at your own endpoints, through the telemetry they already send to Trellix ePO, and tells you which active campaigns are most likely to target an organization in your sector and your geography, which of your devices are exposed to each one, and what countermeasures to apply. 

Campaign and threat-actor prioritization is driven by machine learning, each campaign is mapped to its indicators of compromise and MITRE ATT&CK techniques, and the recommended countermeasures are prescriptive rather than generic. Trellix Insights also associates and prioritizes the CVEs tied to each campaign, so the vulnerability conversation and the threat conversation happen in the same place.

The practical result is a security posture score for your estate and a short list of what to fix first, in the order an adversary would exploit it. The goal, as stated in the Trellix Insights data sheet, is to reduce mean time to detect (MTTD) and resolve threats from months to hours (reducing MTTR). For a SOC that cannot read every advisory, that is the difference between threat intelligence as a subscription and threat intelligence as a daily work queue.

An endpoint assessment has no place to measure this, because Trellix Insights is not an endpoint agent. It is what the endpoint agents make possible.

Data Loss Prevention: The same policy on the endpoint and the wire

DLP that lives only on the endpoint stops the moment data leaves through a channel the agent does not see, such as a server-side email flow, a web gateway, or a file share. Trellix Data Loss Prevention covers the endpoint with Trellix DLP Endpoint Complete, the network with Trellix Network Monitor and Trellix Network Prevent, and stored data with Trellix Discover, which finds and classifies sensitive data across networks and file repositories. All of it is administered from a central, unified console, available on-premises or as SaaS, for policies, event detection, and reporting. File and disk encryption are a core part of the same offering.

On the endpoint, Trellix DLP Endpoint Complete can monitor or block file uploads, copy and paste into web pages and printing from web applications. It can also monitor and block email attachments and block unauthorized devices from connecting. It supports exact data matching, auto-classification, and OCR, and it ships with policies and reports mapped to common compliance frameworks. It also does something that changes user behavior rather than just blocking it. Customizable pop-up notifications and justification requests let an employee explain why they need to move a file, which turns a silent block into a teachable moment and gives the security team a record of intent.

For a regulated enterprise, the question is not whether the endpoint has DLP. It is whether the same classification and the same policy follow the data when it leaves the endpoint. That is a platform question, and it is one an endpoint assessment is not designed to ask.

Trellix IVX: A sandbox that malware cannot tell is a sandbox

Trellix Intelligent Virtual Execution (IVX) is a signature-less, dynamic analysis engine that captures and confirms zero-day and targeted APT attacks, and calls it a sandbox, which undersells it. It detonates suspicious files, web objects, URLs, and email attachments inside a proprietary hypervisor instrumented for over 200 simultaneous executions. The hypervisor is custom-built with countermeasures designed specifically for malware analysis, which is how it exposes the sandbox-aware and evasion tactics that sophisticated malware uses to play dead inside a conventional virtual machine. Multiflow analysis follows a multistage attack across its stages instead of judging each file in isolation, and the engine supports more than 200 file types across Windows, macOS, and Linux.

The reason Trellix IVX belongs in an endpoint conversation is where its verdicts go. The same engine serves Trellix Network Security, which intercepts suspicious objects directly from live traffic and detonates them, and Trellix Email Security. Both products are built to work with Trellix Endpoint Security to identify, validate, and contain compromises. 

A file that the endpoint cannot judge on its own gets a verdict from the same analysis engine that protects the network and the mailbox, and the result comes back to the endpoint. Trellix IVX is available as a cloud service, as on-premises appliances, and as a virtual instance, so it runs in the same air-gapped and sovereignty-sensitive environments the endpoint platform supports.

An endpoint assessment measures the endpoint's ability to detect. It has no column for the analysis engine standing behind the endpoint when a sample is new enough that detection alone is not enough.

Application and change control: Protection for the systems that cannot be patched

Trellix does not offer a standalone patch management product, and we would add the point that sits beside it. A large share of the systems our customers worry about most cannot be patched on any vendor's schedule. For those systems, the question is not how fast you patch but how you stay safe between patches.

Trellix Application and Change Control answers that question with allowlisting. It prevents zero-day and APT attacks by blocking execution of unauthorized applications, and it does so on connected or disconnected servers, virtual machines, endpoints, fixed devices such as point-of-sale terminals, and legacy systems. A dynamic allowlisting model automatically accepts new software that arrives through trusted channels, using trusted users, local groups, certificates, processes, and directories, so the list maintains itself instead of consuming an administrator’s time. Signatureless memory protection keeps even allowlisted applications from being exploited through buffer overflow attacks on Windows.

The change control is half of the product, which is what auditors ask for. File integrity monitoring and change prevention record who changed what, when, and with which program, down to file and registry content, which is why the product is positioned for PCI DSS and Sarbanes-Oxley environments. All of it is managed through Trellix ePO.

For manufacturing, industrial, and public-sector buyers, this is often the product that makes the endpoint decision. A plant-floor controller running an operating system that reached end of life years ago does not need a faster patch cycle. It needs to run only what it was built to run, and nothing else, and to prove that to an auditor. That is what Trellix Application and Change Control does, and it sits outside an endpoint assessment's frame.

What else sits behind the console

The four capabilities above are the ones customers ask about most, but they are not the whole list. Two others deserve a mention, because each one changes what the endpoint can do.

Network security and email security share the endpoint's verdicts. Trellix Network Security watches east-west traffic with more than 180 lateral-movement rules, machine learning for exfiltration detection, JA3 fingerprinting of encrypted sessions, and web-shell detection. When deployed inline, it drops threats on the wire before they reach an endpoint.

Its alerts correlate with Trellix Email Security through a central management system and with Trellix Endpoint Security for validation and containment. Customers who run the three together get the network's and the mailbox's view of the same attack, in the same investigation.

The question to ask any endpoint vendor

The point of this post is that the organization whose endpoint estate is too varied, too regulated, or too critical to run on the newest operating systems alone needs more than an endpoint agent, and that organization is the one Trellix has served for decades.

So when you evaluate endpoint platforms, ask every vendor the same questions we would ask ourselves. What is behind the agent, and is it managed from the same place? For Trellix, the answer is Trellix Insights, Trellix DLP across endpoint and network, Trellix IVX, Trellix Application and Change Control, Trellix Network Security, Trellix Email Security, the Trellix Advanced Research Center, and Trellix Wise, all operating under Trellix ePO.

If your environment looks like the one described here, we would like to show you how our security solutions run in it. Request a demo that goes beyond the endpoint or talk to your Trellix partner about a security portfolio briefing.
