Today’s security tool stacks have become ridiculous.
Every year, security leaders are faced with a dozen new tools and technologies—each one essential in the fight against cybercrime—and have to figure out for themselves which will add value… and which will simply add complexity.
To make matters worse, most security tools do both. They may provide valuable new capabilities, but they also require more training, more complicated workflows, and sometimes even more personnel to operate.
But now and then, something bucks this trend by adding value while reducing
complexity for security teams. XDR is one of these.
XDR stands for Extended Detection and Response, a category of cyber security solutions that evolved from Endpoint Detection and Response (EDR) tools.
Gartner defines XDR as SaaS-based threat detection and incident response tools that combine several security product categories into a unified solution. Critically, where EDR tools focus exclusively on threats to endpoint devices like laptops and smartphones, XDR tools monitor telemetry and data sources across the entire business environment.
So, what functionality does an XDR tool have? This is a somewhat tricky question to answer.
In the Market Guide, Gartner notes that an XDR solution should combine the functionality of at least three security solutions on the front end—most commonly a selection of the following:
Each XDR vendor in the space takes a slightly different approach based on the types of solutions it produced before the advent of XDR. However, by combining at least three—often more—solutions, an XDR tool can ensure a comprehensive view of malicious activity across a network environment.
On the back end, Gartner believes an XDR tool should provide:
There’s an obvious difference between EDR and XDR. EDR tools focus exclusively on endpoint threats, while XDR tools take a wider view of the entire IT environment, including endpoints, cloud infrastructure, email, and more.
However, there’s more to it.
EDR tools focus exclusively on visibility, threat detection, and response for network endpoints. Although there are naturally some differences in functionality between EDR tools developed by different vendors, they essentially perform this single role.
On the other hand, XDR tools have a much wider remit in terms of the assets they protect and functionality. XDR tools provide a much wider range of capabilities, including automation and orchestration, data analytics, and a broader range of integrations. For example, all focused on improving efficiency and efficacy for SOC and incident response teams.
XDR aims to deliver integrated visibility and threat management across an organisation’s entire environment, all within a single solution. This is intended to simplify security architecture, improve efficiency and reduce costs while boosting security outcomes.
The Gartner Market Guide for Extended Detection and Response notes that XDR has particular value for SMEs that may not have SIEM or SOAR tools. XDR tools provide log management and automation capabilities tailored to incident detection and response, which are usually only available to larger organisations with dedicated SIEM and SOAR solutions.
It’s worth noting, however, that XDR can’t replace SIEM or SOAR tools for larger organisations because those tools have a much broader remit than pure incident detection and response.
Today’s security teams are stretched to breaking point—and this is true whether we’re talking about an enterprise-level SOC or a lone security professional in an SME. As the volume and sophistication of cyber threats rise—which they do every year—this challenge only worsens.
As a platform that combines the capabilities of multiple security solutions while centralising the collection and analysis of security data from across the environment, XDR has much to offer security teams. Rather than adding more complexity to already elaborate stacks, XDR poses a rare chance to add important new security capabilities while reducing the burden on security teams.
Some of the top XDR benefits for today’s security teams include:
Getting excited about another new security solution (and acronym) is sometimes hard. However, XDR solutions pose a rare opportunity for today’s organisations, particularly smaller and mid-sized organisations that don’t have the budget for fancy SIEM and SOAR tools.
