1. Summary

Enterprise cybersecurity is typically composed of multiple solutions from various vendors, combined with a security information and event management (SIEM) and/or security orchestration, automation and response (SOAR) product to help security analysts detect and respond to cyberattacks. Traditionally, most SIEM/SOAR solutions came with out-of-the-box threat detection capabilities; however, their effectiveness relied heavily on a human in the loop to fine-tune the systems for the particular environment. Any such solution was limited, therefore, by the knowledge of the incumbent security staff and required extensive maintenance to keep up with the ever-changing threat landscape. This limitation too often resulted in less-than-intelligent detection and a crippling overabundance of alerts; real threats were drowned out by noise and remained undetected.

Now, a newer kind of threat detection technology—extended detection and response (XDR)—distributes detection and response across the security stack to provide ubiquitous coverage from endpoint to cloud by delivering unified visibility, control, and protection. XDR solutions collect telemetry and leverage artificial intelligence (AI), machine learning (ML), and other statistical analysis methods to correlate event logs and then evaluate them against intrusion response frameworks. Additionally, XDR systems integrate threat intelligence to enhance and improve threat detection capabilities. Importantly, solutions—and threat detection—are no longer dependent on the knowledge of security staff.

The GigaOm Key Criteria and Radar reports provide an overview of the XDR market, identify capabilities (table stakes, key criteria, and emerging technologies) and non-functional requirements (evaluation metrics) for selecting an XDR solution, and detail vendors and products that excel. These reports give prospective buyers an overview of the top vendors in this sector and help decision-makers evaluate solutions and decide where to invest.
