EDR (Endpoint Detection and Response) is the evolution of the traditional antivirus. Where a classic antivirus detects known threats based on signatures, EDR monitors endpoint behaviour (computers, servers, devices) in real time, uses behaviour-based detection and machine learning, and supports active response — isolate the endpoint, terminate malicious processes, collect forensic evidence.
The difference is substantial in modern attacks. Current ransomware uses legitimate operating-system tools (living-off-the-land) that go unnoticed by signature-based antivirus. EDR observes the pattern — a legitimate process opening hundreds of files quickly and modifying them — and raises an alert before the attack completes. The SOC team has minutes or hours to respond, rather than discovering it after the fact.
INFOS implements EDR in cybersecurity architectures for customers in sectors where the risk justifies it — industry with critical intellectual property, distributors with 24/7 operation, retail with large transaction volumes. The choice of product (Microsoft Defender for Endpoint, CrowdStrike, SentinelOne, among others) depends on the existing ecosystem and the budget.
