What is Endpoint Detection and Response (EDR)?

Endpoint detection and response (EDR), also called endpoint threat detection and response (ETDR), is a security strategy that’s designed to continuously monitor for potential cyberthreats—and proactively respond to them. But what exactly is this strategy, and how does it benefit your organization?

How Does Endpoint Detection and Response Work?

EDR is designed to keep your endpoints—the devices at the physical end of a network (e.g., laptops, desktops, tablets, and servers)—secure. The high-level vision is to continuously monitor endpoint data for suspicious activity. If you notice something off, you can take proactive action and remove the threat before it causes any real damage.

You can think of the responsibilities of an EDR strategy as:

  •         Active monitoring. First, EDR is designed to continuously monitor endpoints for potential threats. This is a form of data collection, and ensures any suspicious activity can be noticed.
  •         Data analysis. Second, EDR analyzes endpoint data to identify potential threat patterns.
  •         Automatic responses. The ideal EDR system then automatically responds to identified threat patterns, based on rules set by the user. In some cases, threats can be instantly removed or contained. In other cases, the EDR system simply notifies human security personnel.
  •         Forensics and research. EDR also requires ongoing forensics, research, and analysis to identify new threats and learn new kinds of suspicious activity.

Key Benefits of EDR

EDR has several benefits:

  •         Continuous monitoring. Cyberattacks can happen anywhere, at any time, so it’s important to have some kind of continuous monitoring in place. EDR grants you this capability, giving you a constant eye on your devices.
  •         Endpoint security. Endpoints are one of the most common entry points for cyberattacks. By making them the critical focus of this part of your security strategy, you can greatly minimize the potential of a threat.
  •         Automatic action. Your IT security personnel don’t have the time or capacity to respond to every threat manually. That’s why EDR includes automatic and proactive action to respond to threats, based on rules you establish.
  •         High catch rates and low false positives. Modern endpoint security solutions offer high catch rates and low false positives—so you don’t have to worry about threats slipping through, and you don’t have to worry about false alarms.
  •         Ongoing improvement. Thanks to ongoing forensics and research, most endpoint security solutions can be continuously updated. They can learn about new threats and vulnerabilities, and improve their capabilities to serve end users better.

Why Is EDR Important?

EDR is important because it has the potential to keep your organization secure. IT departments, especially those in large companies, are responsible for managing upwards of thousands of endpoints across an entire network. In the largest organizations, endpoints can total half a million or more. And because each endpoint is the potential target of a cyberattack, every endpoint on your system needs to be considered a potential attack vector.

EDR enables your security team to actively and continuously monitor these endpoints for threats, automatically taking action whenever suspicious activity is detected.
