EDR and XDR — intelligent protection where attackers operate

EDR (Endpoint Detection & Response) is the successor to antivirus — it detects threats behaviorally, not just through signatures. XDR extends visibility to the network, cloud, and identity. Together they form a detection and incident response platform.

What we deploy

EDR and XDR feature scope

EDR and XDR are a fundamental shift in endpoint protection — from reactive blocking to active detection and response.

Behavioral detection and AI

Real-time analysis of process and file behavior — detecting malicious code without signatures. AI and machine learning identify anomalies unknown to any prior system. Protection against zero-day malware and fileless attacks.

Ransomware protection

Detecting characteristic ransomware behavior patterns (mass file encryption) and immediately stopping the process. CryptoGuard (Sophos) — automatic rollback of encrypted files from Shadow Copies. Active, not just signature-based, protection.

Threat Hunting

Proactive threat hunting in the environment by experts (MDR) or your own security team (SOC). Endpoint telemetry analysis — attackers sometimes operate for months before being detected.

XDR — extended detection

XDR correlates data from endpoints, network (NDR), cloud, and identity (SIEM) into a single incident context. Instead of separate alerts from each system — one incident with the full attack history (kill chain).

Vulnerability management and patching

Software and version inventory. CVE identification in installed applications. Integration with patch management systems. Prioritization of vulnerabilities by risk for the specific environment.

Isolation and incident response

Isolating an infected endpoint from the network with one click — no physical access required. Collecting forensics (processes, logs, files) without disrupting the system. Rolling back malicious changes after neutralizing the threat.

Antivirus protects against yesterday's threats — EDR against today's

Signature-based antivirus won't detect a threat it doesn't know. EDR detects threats whose signatures don't yet exist.

Over 70% of modern attacks use fileless techniques — without an executable file on disk. Traditional antivirus is blind to them. EDR with behavioral detection is the minimum for any company handling sensitive data.

FAQ

EDR and XDR questions

Antivirus compares files against a signature database — if the file is unknown, it passes. EDR analyzes process behavior in real time — if a program starts encrypting files en masse, EDR stops it even without a signature. The difference is like a guard recognizing a thief from a photo vs a guard reacting when someone behaves like a thief.
XDR (Extended Detection & Response) is EDR extended with network, cloud, and identity data. Instead of separate alerts from the firewall, EDR, and SIEM — XDR correlates them into a single incident with full context. For companies with a mature SOC and many security tools — XDR significantly accelerates incident analysis.
Modern EDR is designed with minimal performance impact — typically below 1–3% CPU. Agents like Sophos Intercept X or Cortex XDR are optimized and don't cause noticeable slowdown. Older or poorly configured solutions can affect performance — that's why selection and configuration matter.
Yes — modern EDR includes antivirus features (blocking known threats via signatures) plus behavioral detection, ransomware protection, and incident management. There's no need to install a separate antivirus alongside EDR. Most vendors recommend replacing legacy AV with EDR.
