You thought Elastic only did SIEM? Think again!

Elastic solved the hardest problem of XDR before most vendors even recognized it: scaling to massive data volumes with real-time speed and advanced analytics across your entire environment — whether on-premises, across multiple clouds, or distributed globally. For over 15 years, we’ve led the way in operationalizing security data at scale — something many EDR vendors are still scrambling to figure out. While others struggle with data limits, sluggish queries, and siloed detections, Elastic delivers true, unified detection and response across endpoint, cloud, network, and third-party data — without compromise.

Modern attacks rarely stay confined to a single system — and neither should your defenses. Elastic Security brings together SIEM and EDR capabilities into a single, scalable platform, giving security teams comprehensive, correlated visibility across endpoints, cloud workloads, networks, and user activity. This integrated approach empowers analysts to detect, investigate, and respond to multi-stage lateral threats with speed and precision. By correlating endpoint telemetry with broader security data via hundreds of out-of-the-box integrations, Elastic enables true XDR outcomes: faster detection of complex attack patterns, reduced investigation times, and a more efficient, streamlined security operation. With Elastic, you break down data silos, regain control of your security data, and stay ahead of advanced threats with the context your team needs to act decisively.

In today’s fast-paced threat landscape, speed and precision are everything. Elastic Security puts AI to work for your team with powerful, analyst-centric features designed to cut through noise and accelerate response. Attack Discovery automatically surfaces high-risk attack paths and suspicious behaviors by analyzing detections and endpoint telemetry in real time — no manual pivoting or hunting required. Paired with the Elastic AI Assistant, analysts can instantly summarize incidents, get contextual explanations, and receive guided next steps tailored to each investigation. Automatic Import streamlines onboarding and normalization of custom data, giving analysts immediate visibility and context regardless of the data source.

Elastic Defend is the endpoint protection integration within Elastic, delivering real-time prevention, detection, and response capabilities. It protects against a broad spectrum of threats — including malware, ransomware, fileless attacks, and adversary techniques like process injection and credential dumping — while continuously monitoring for malicious behaviors at both the host and process level. In this section, we’ll dive into how Elastic Defend detects, blocks, and responds to these attack types to maintain endpoint security.

Elastic Extended Security helps protect your devices from malware on Windows, macOS, and Linux by using multiple layers of defense. It scans files when they’re saved or run to catch bad software before it can cause harm. Using smart detection methods like YARA signatures and threat intelligence lookups, it can spot threats quickly. On Windows and macOS, Elastic Extended Security also uses a risk score model using machine learning, called MalwareScore, to help prioritize the most dangerous threats. Plus, it lets you block unwanted programs, quarantine suspicious files, and even restore them if needed. On Windows, it goes a step further with features like self-healing and driver protection to keep your system running smoothly and safely. Together, these tools work quietly in the background to keep your endpoints secure without slowing you down.

When it comes to ransomware, Elastic Extended Security offers strong protection primarily for Windows endpoints. It both watches for suspicious behaviors that indicate ransomware activity and uses “canaries” — special decoy files designed to detect when ransomware tries to encrypt data. Elastic Extended Security can also protect the Master Boot Record (MBR), which ransomware often targets to lock you out of your system. If ransomware is detected, Elastic Extended Security can automatically kill the malicious process to stop the attack in its tracks.

A fileless attack is a type of cyber attack that doesn’t rely on downloading malicious files — instead, it runs harmful code directly in your device’s memory, making it harder to detect with traditional security tools. Elastic Extended Security helps protect your devices from these tricky memory-based and fileless attacks on Windows, macOS, and Linux. It uses YARA scanning to spot suspicious code patterns across all platforms. On Windows, Elastic Extended Security also monitors memory threat system behaviors in real time, identifying suspicious process activity, in-memory injection techniques, and other indicators of fileless attacks. If a threat is detected, Elastic Extended Security can kill the malicious process immediately to stop the attack. On Windows, it also includes self-healing features that automatically repair affected parts of the system. This multi-layered approach helps keep your endpoints safe from stealthy attacks that try to fly under the radar.

Malicious behavior protection focuses on spotting harmful actions on your devices rather than just known malware files. Elastic Extended Security monitors for suspicious behavior across Linux, macOS, and Windows using powerful detection methods to identify threats in real time. It looks for a wide range of malicious activities, such as unauthorized privilege escalation, suspicious process spawning, unusual network connections, or attempts to disable security tools. When it detects these behaviors, Elastic Extended Security can kill the harmful process — or even the entire process tree — to stop the attack from spreading. By focusing on what attackers do instead of what they look like, Elastic Extended Security helps catch stealthy threats before they cause damage, keeping your endpoints safe and secure.

Elastic Extended Security selectively collects system activity data to detect and prevent as many threats as possible, while carefully balancing storage use and system performance. By design, Elastic Extended Security focuses on collecting security-relevant activity rather than a complete record of all system events. The event data it generates may be aggregated, truncated, or deduplicated as needed to optimize for effective threat detection and prevention. Recent updates to our default settings have reduced event volumes by as much as 68%, helping you lower data storage costs and improve system performance. Want to see how we did it?

Elastic Extended Security is powered by more than just technology — it’s fueled by the expertise of Elastic Security Labs. Our dedicated threat research team continuously tracks the latest adversary behaviors, malware campaigns, and endpoint attack techniques, translating those insights into actionable protections for Elastic Extended Security users. From new detection rules and machine learning models to advanced prevention capabilities, Security Labs ensures Elastic Extended Security stays ahead of evolving threats. By actively contributing open detections, research reports, and malware analyses to the broader security community, Elastic Security Labs strengthens defenses for both our customers and Extended Securityers everywhere.

Few things crank up the pressure in a SOC like an endpoint alert that might signal an active threat. Elastic Extended Security equips analysts with a powerful set of response actions to quickly contain and neutralize endpoint threats before they escalate. Right from the Elastic Security UI, analysts can isolate a host, kill malicious processes, and collect vital forensic artifacts like memory dumps or file metadata. These actions can be executed remotely and at scale, helping teams cut dwell time and stop attacks in their tracks. Powered by Elastic’s agent-based architecture, response actions are fast and reliable, and they work across diverse environments — giving SOC teams the confidence and control they need when it matters most.

Plus, Elastic’s truly vendor-agnostic approach enables seamless response orchestration across third-party platforms like CrowdStrike, Microsoft Defender for Endpoint, and SentinelOne — empowering SOC teams to execute containment and remediation directly from Elastic Security.
