Join SE Labs for in-depth discussions on cyber security testing
The SE Labs Workshop in Wimbledon on 2 July 2025 promises to be an important event for cyber security professionals focused on the future of security testing. Available to both in-person and virtual attendees, this one-day event brings together industry experts and security vendors to share insights on critical topics such as testing security for MSSPs, attack chain simulation, and a significant shift in endpoint protection with the transition to Windows 11.
Business vs. consumer cyber security needs
Attendees will gain a deeper understanding of the increasing complexities in endpoint testing, including varied attack types, a separation between business and consumer security needs, and MacOS-specific testing.
As we launch our first XDR security testing program, we’d like to explain how SE Labs tests XDR solutions. But first, what is XDR? The industry has various opinions!
Extended Detection and Response (XDR) is a combination of security products working together. Its goal is to provide defenders with a coherent response to attacks. This joined-up approach can help defenders identify different stages of each attack without scrambling around using many different tools.
XDR is supposed to make things simpler for defenders, providing a dashboard (a ‘single pane of glass’) that provides complete insight into a network’s security situation.
SE Labs has produced the first comprehensive method of testing XDR solutions. The components of an XDR solution under test can be sold by the same company or different security vendors.
For example, we can test a solution that combines a Cisco email security gateway with endpoint security from CrowdStrike. And we can test a Cisco email security gateway alongside Cisco’s own endpoint security.
An SE Labs XDR test can assess combinations of cloud services such as email and identity alongside on-site firewalls, endpoint protection and Internet of Things (IoT) security products. If there is an XDR integration available, we can test it.
XDR in detail
There are plenty of definitions of XDR in the market. At SE Labs we define an XDR solution as a combination of at least two products, each of different types.
The products deployed do not need to be from the same vendor.
They must either talk to each other or a third management system, which provides the overall dashboard for detection and response.
Here is a list of products that can make up an XDR solution. They can be variously installed on-site or in-cloud:
The SE Labs testing team behaves like a real customer, allowing security vendors to provide and configure their products exactly as they would in a production environment. The testing team then change roles, behaving as attackers. It runs attacks from the beginning to the end of the attack chain, while also monitoring the security system for detections and other behaviour.
As the testers know every stage of the attack in detail, they assess how completely the products (and, more importantly, the combination of products) detect the different parts of the attacks as well as the entire attack episode.
In this way, the SE Labs testing team tests like hackers and analyses like defenders. The results are useful and realistic.
Who should care?
The results are useful, but for whom?
There are two main groups that benefit from SE Labs XDR testing.
Security sellers
The first group comprises the security vendors themselves. They can identify areas where detection is weaker and needs improvement. They may also discover areas where integration between different products could be better. The SE Labs test provides a good opportunity to make changes and strengthen the products, which means stronger protection for their users.
When things work well, security vendors can use SE Labs’ test results to highlight their successes in the market.
Security buyers
Secondly, but no less importantly, security buyers can use either public or bespoke test results to help choose the most appropriate products for their own organisations. Having real test data, showing how products handle threats in the real world, reduces risk and improves value for money.
Not every product works equally well, and that applies not only to general security effectiveness but also integration with other products. Security testing results are always an important resource before investing in a product. They are doubly so when looking to buy or build an XDR solution.
XDR Examples
Here are some examples of XDR implementations. We’ve chosen vendors and products randomly, but sensibly. For example, it makes sense to combine endpoint and email security solutions with a central data repository like a SIEM. It also makes sense to combine products from different market-leading providers, or to use all of the products from a single one.
Infer no judgement about the suitability of specific vendors from this example list:
Microsoft Defender (endpoint); Microsoft Defender (email); Splunk Cloud Platform (SIEM)
In the first example we have combined the detections and other data from two Microsoft products (endpoint and email) and sent them to a cloud-based platform that claims to provide insight into all activity.
In the second example, a simple setup combines the detection capabilities of endpoint and email threat detection products from different vendors.
Thirdly, some security companies are able to provide products for many different areas, such as firewalls, endpoint, email and web security. In this example, one vendor provides and manages all the components of the detection system.

A route to accessing Windows Early Launch Antimalware (ELAM).
Anti-malware products monitor Microsoft Windows for malware. They try to notice when new, unwanted software runs, but some malware can be extra sneaky and hide. To get ahead of the game anti-malware products can start monitoring the system early, before other software applications start. The security software then watches as the various programs load during the Windows boot-up process.
SE Labs works with security companies to help develop and validate their products. When a security company works with SE Labs it gains two main benefits. If the product performs well it gains a much sought-after award. If it encountered problems the testing team will provide valuable information to help fix the issues.
