Quick Ans: Endpoint Detection and Response (EDR) is a cybersecurity technology that continuously monitors endpoints like laptops, desktops, and servers for evidence of threats, performs automatic actions to mitigate them, and helps security analysts detect and remediate threats before they spread. Key capabilities include threat detection, incident response, threat containment, and forensic investigation. The global EDR market was valued at US$483 million in 2025 and is forecast to reach US$751 million by 2032.
Your antivirus software blocks a suspicious file. But what happens when the threat doesn’t use a file at all? What if attackers are already inside your network, using stolen credentials and legitimate tools to move around undetected? This is where Endpoint Detection and Response comes in.
Endpoint Detection and Response, commonly known as EDR, is a cybersecurity technology that continuously monitors endpoints for evidence of threats, performs automatic actions to mitigate them, and helps security analysts detect and remediate threats before they spread throughout the network . Unlike traditional antivirus software that relies on known malware signatures, EDR uses behavioral analysis and machine learning to identify suspicious activities that might indicate an attack .
The importance of EDR has grown dramatically as cyberthreats have evolved. Studies estimate that as many as 90% of successful cyberattacks and 70% of successful data breaches originate at endpoint devices . Traditional endpoint security tools can’t detect or neutralize advanced threats that sneak past them, allowing those threats to lurk and roam the network for months . EDR picks up where these traditional solutions leave off, providing the visibility and response capabilities that modern organizations need.
