What EDR is
Endpoint Detection and Response records important activity on workstations and servers, looks for suspicious behaviour and gives responders context about what happened before and after an alert.
Problems it can help detect
Examples include ransomware behaviour, unusual scripting, credential dumping, suspicious remote-control tools, persistence attempts and activity moving from one computer toward another.
Why an alert still needs a response process
A security product is not a complete outcome. Someone must review important alerts, isolate affected systems, preserve evidence and decide whether passwords, sessions or other devices are also involved.
How to reduce endpoint risk
Keep operating systems and applications patched, remove unnecessary administrator access, use MFA, control applications and maintain tested backups alongside endpoint protection.
Who should consider EDR
Businesses holding client information, relying on Microsoft 365, using remote access or operating several computers should assess whether basic antivirus provides enough visibility and response capability.
