Overloaded security teams, poor visibility, and threat alert overload have quite an impact when it comes to detecting and effectively responding to cyber threats. Since today’s cyberattacks are extremely tricky and complex, to the point of hiding throughout different layers within an organization, it is important to understand the value of Extended Detection and Response.

What is Extended Detection and Response (XDR)?

We can define Extended Detection and Response as a cross-layered detection and response tool. Simply put, this technology collects and then correlates data over a variety of security layers, such as endpoints, emails, servers, clouds, and networks. This means that XDR can enable your security team to detect, investigate, and respond to threats across multiple layers of security, and not just focusing on the end-point detection.

XDR makes room for improved security, awareness, and response capacity as well as enhanced productivity, all while reducing costs.

How Does Extended Detection and Response Work

XDR helps detect malicious threats by conducting an in-depth analysis of both internal and external traffic to identify potential attacks. In addition, it applies integrated threat intelligence, which includes details on known attack strategies, sources, and tools across a wide variety of vectors, and therefore has the capacity to prevent similar attacks in the future and detect zero-day vulnerabilities.

It offers an efficient graphical timeline that can shed some light on the questions you are seeking an answer for:

  • How did I get infected?
  • Which was the entry point?
  • What is the origin of the attack?
  • Were there other parts involved?
  • How did the threat spread throughout the system?
  • Were other users exposed to the threat?

Understanding the Benefits of Extended Detection and Response

The easiest way to understand the advantages of Extended Detection and Response, is to think of it as an AI-based security system. The main goal of XDR is to provide you with the full set of visibility that is connected throughout all of the endpoints of a network’s infrastructure. This leads to conjoined remediation, improved attack understanding, and unified threat hunting.

One of the most important benefits of XDR is data collection. Nevertheless, employing analytics and intelligence can manage better security via faster detection.

Another benefit is turning information into insight and action when security analytics is combined with threat intelligence.

Finally, thanks to the logical connections from the data, XDR allows insightful investigations. This translates to XDR bringing a tactical approach to threat detection, which includes:

  • Fast identification of hidden and sophisticated threats;
  • Responding to threats across multiple layers of security;
  • Increasing the productivity of the operational security personnel;
  • Conducting investigations more efficiently.

Wrapping It Up…

To sum things up, it’s important to acknowledge that Extended Detection and Response enables an organization to reveal cybersecurity risks, monitor them, and estimate how much exposure they result in. It gives an organization the required defense it requires for dealing with advanced threats and provides security teams with the tools they require to deal with these threats.

And speaking of proper tools, our Heimdal™ Security Endpoint Prevention Detection and Response (EPDR) Software consists of four separate solutions unified in one threat dashboard, namely:
