Elastic Extended Security, born from the acquisition of Endgame, brings years of battle-tested EDR and threat prevention expertise directly into Elastic’s Search AI Platform. This isn’t a bolt-on or third-party integration; it’s a native, deeply embedded component that redefines what’s possible with XDR.

As data volumes grow exponentially, traditional EDR tools hit walls. Elastic doesn’t. Only Elastic can deliver true XDR: natively correlating endpoint, network, user, and cloud telemetry at search speed, across petabytes of data, all in a single platform.

But Elastic goes further:

Best-in-class endpoint built in: Our agent protects Windows, macOS, and Linux with the award-winning prevention and detection capabilities originally pioneered at Endgame and evolved into a scalable platform for modern threats. Advanced malware, behavioral, memory, and ransomware defenses are included out of the box.
Hybrid endpoint, real-world ready: Most enterprises rely on multiple endpoint vendors, and Elastic meets them where they are. Elastic Security’s vendor-agnostic platform seamlessly operationalizes data from third-party EDR tools alongside Elastic Extended Security’s own endpoint agent — all within a unified detection and response workflow. No silos. No pivoting.
Unlimited deployment model: With Elastic, every user gets unlimited agents. Scale up during incidents. Deploy widely during mergers and acquisitions. Build a resilient baseline across thousands of machines — without hidden per-endpoint pricing. Elastic delivers a mission-ready platform that protects today’s infrastructure and scales to meet tomorrow’s complexity. This is XDR the way it was meant to be: flexible, powerful, and unified.

Endpoint security is essential, but it can sometimes introduce system slowdowns or conflicts that affect performance. Troubleshooting these issues manually is complex and time-consuming, often delaying the deployment of security tools and creating critical visibility gaps across your environment.

Elastic’s Automatic Troubleshooting uses AI to automatically identify third-party antivirus and security software causing endpoint performance issues and slowing your users down. We even help you fix these conflicts, with fast one-click exclusions.

This gives security teams fast, clear insights and guided steps to resolve performance problems — helping you maintain strong security without sacrificing endpoint performance or user experience.

Speed and context are everything in security investigations — and that means having all your data, instantly accessible, whenever you need it. Elastic Security is built to handle security telemetry at scale, so you can retain, search, and analyze vast amounts of data without compromise.

With searchable snapshots and flexible data tiers, Elastic lets you keep months or years of endpoint, cloud, and infrastructure data searchable — without blowing your budget. No more choosing between retention and performance.

Paired with powerful investigation tools like Timeline, Session View, and an interactive process analyzer, analysts can quickly trace events, pivot between related activity, and uncover the full scope of an incident. The result: faster investigations, deeper insights, and decisions based on complete, reliable data. And thanks to our vendor-agnostic approach, these investigative workflows work seamlessly whether telemetry comes from Elastic, a third-party EDR, or a mix of both — ensuring investigations stay efficient and comprehensive, no matter what tools you’re running.

At Elastic, we know SOC analysts rely on transparency and trust to Extended Security against evolving threats. That’s why we made our protections-artifacts repository fully open, sharing the exact detection logic behind Elastic’s endpoint security — including YARA signatures and rules for Windows, macOS, and Linux. This level of visibility lets you understand what’s running under the hood, customize detections to fit your environment, and collaborate with the community to sharpen protections.

Openness isn’t just about sharing code — it’s about empowering you to stay ahead of attackers and keep your organization secure. Elastic also runs a public bug bounty program that covers EDR behavior detection rules, rewarding researchers for identifying ways to bypass detections. This helps security teams strengthen Elastic Extended Security’s protections and stay ahead of evolving attack techniques.

We think Elastic Extended Security is one of the best protection engines in the industry — but don’t just take our word for it. Independent third-party testing continues to validate the strength of our endpoint security capabilities.

In the latest AV-Comparatives Business Security Test (April–May 2025), Elastic Extended Security achieved a 100% protection rate against 200+ advanced attack scenarios and 1,000+ real-world malware samples. That’s top-of-the-table performance in one of the industry's most rigorous evaluations.

And it doesn’t stop there. Elastic Extended Security also earned a Grade A certification from VB100, following its intensive real-world malware and false positive testing.

These results reinforce what our customers already experience: Elastic Extended Security consistently delivers reliable, high-fidelity protection against today’s most sophisticated threats — while staying lightweight and easy to manage as part of the Elastic Security platform.
