What is endpoint detection and response (EDR)?

Endpoint detection and response (EDR) is an advanced layer of endpoint security that provides real-time visibility across endpoints and servers. It helps organizations accelerate the detection of suspicious activity, enables threat hunting and the investigation of incidents, and allows security teams to respond quickly and with precision. EDR strengthens security operations by: Delivering continuous, real-time telemetry from endpoints and servers. Accelerating detection and reducing incident response times. Equipping teams with tools to contain, investigate, and remediate threats.

Why is endpoint detection and response (EDR) important?

Modern cyber threats are increasingly sophisticated, fast-moving, and designed to bypass traditional security tools. EDR provides the visibility, detection capability, and rapid response required to prevent breaches before they begin.

EDR collects endpoint telemetry, analyzes behavior to identify anomalies, and highlights high‑risk events. Security teams can investigate root cause, trace attack paths, and take action to contain threats before they spread.

What are common EDR use cases?

Organizations use EDR to: Detect and contain ransomware. Investigate fileless attacks. Detect suspicious authentication activity. Monitor suspicious PowerShell or command-line activity. Track lateral movement. Support live response and post-incident investigation.

How does EDR differ from antivirus or endpoint protection (EPP)?

Antivirus blocks known threats. EPP adds prevention-first technologies such as anti-exploitation and ransomware protection to block known and unknown threats. EDR goes further by delivering continuous monitoring, threat detection, and automated and human-led incident response capabilities to stop advanced threats that prevention may miss.

How does EDR reduce risk and improve endpoint visibility?

EDR provides continuous insight into endpoint activity and highlights high‑risk behavior. Organizations benefit from faster detection, quicker containment, reduced dwell time, and measurable improvements in mean time to detect (MTTD) and mean time to respond (MTTR).

What makes Sophos EDR different?

Sophos EDR combines prevention-first protection with intelligent detection and response in a unified platform. AI-accelerated features streamline detection and response, helping to prioritize where to focus your attention, quickly understand the threat with world-class threat intelligence, recommended next steps, and rich and real-time insights to quickly and thoroughly respond to threats.

How does Sophos EDR protect against ransomware?

Sophos EDR detects malicious encryption behavior at the file level — even when the encryption originates from another compromised device on the network. If ransomware activity is confirmed, file rollback can automatically restore affected data to a safe state.

How does Sophos EDR improve investigation and reduce alert fatigue?

Endpoint telemetry is stored in the Sophos Data Lake for real-time and historical analysis. AI-driven prioritization surfaces fewer, higher-confidence alerts, while AI Search and AI Case Summary translate complex activity into clear, actionable insights.

How do Sophos EDR and Sophos MDR work together?

Sophos EDR provides the tools for protection, detection, and response. Sophos MDR adds 24/7 expert-led monitoring, threat hunting, and containment, giving organizations the option to manage EDR themselves or offload operations without adding headcount.

Sophos vs. the competition

YOUR CHALLENGES

Protect and monitor for suspicious activity and evasive threats

Adversaries are increasingly deploying sophisticated tactics to evade being blocked by preventative cybersecurity solutions. Real-time and continuous monitoring is necessary to identify human-led attacks and prevent breaches.

Download solution brief

Sophisticated attacks using evasive techniques

Attackers try to avoid triggering preventative security tools to give themselves more time for a thorough breach and the opportunity to monetise their attack.

Prioritising what to investigate

Security tools can produce a significant number of alerts. Knowing which alerts are essential to investigate can be the difference between detecting a threat and missing it.

Team skills and agility

Organisations may lack the necessary knowledge and skills to respond effectively to advanced threats, increasing risk and potential impact.
