Groups of malware are constantly on the lookout for new ways to infiltrate Windows systems. They might disguise their malicious code as a harmless Windows utility app or inject attack code into open source software so it can act as springboard for cruel attacks later on. The AV-TEST lab recently conducted its Advanced Threat Protection test – or ATP test, for short – and evaluated the response of 21 protection products for consumer and corporate users in individual attacks. The lab documented step by step how and when the defensive mechanisms of security packages engaged and fended off cyberattackers. The results clearly demonstrate the current power balance between malware and security software.

Traditional testing can offer a decent picture of the effectiveness of any one security solution for companies at a given instant; yet, an endurance test is able to delve deeper. This is especially the case with the endurance test because it took place over a period of 6 months and it included both Windows 10 and 11. Many companies are looking to use the extended support for the now discontinued Windows 10, or they are in the process of migrating their systems to Windows 11. So it is vastly more relevant now to know how well the 15 solutions in the endurance test can provide protection to companies and their employees using either operating system.

Although Microsoft has given Windows 10 users an extension of one more year in terms of Windows updates, the changeover has only been postponed – it's still going to happen. Many users are wondering whether their current protection package will continue to work securely after the switch to Windows 11. This question is answered by the current endurance test of 12 products for consumer users. The endurance test was launched under Windows 10 and concluded after six months under Windows 11. The answer is yes: the security vendors perform well under both systems in terms of protection, performance, and false positives.

The series of Advanced Threat Protection tests provides an impactful demonstration of how effectively security solutions – for both consumer users and corporate users – can withstand real attacks by ransomware or info stealers. The individual results of these ATP tests are already highly revealing. Yet, even greater insights can be gained when studying the results over a longer time period: the endurance test clearly shows which security solution stands out through consistently strong threat prevention. The endurance test conducted over six months under Windows 10, still the most widely used operating system, had a few surprises in store – and confirmed some things that experts already suspected.
