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.

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.

Take a look at any study on the subject of malware: ransomware and info stealers have consistently been on the front line of cybersecurity threats for years now. Good protection software detects attackers before they wreak devastation. But what happens if the attackers are not readily detected by the software? This question is answered by the Advanced Threat Protection test – ATP test for short. In the process, the experts in the lab examine whether the current 20 protection solutions detect the malware directly or whether further protection mechanisms only protect a system from damage in later stages. The test reveals that even if malware is not detected, the battle is far from over. Many a protection package tussles with an attacker over many rounds, ultimately leading security to victory.
