Recently, many Mac users have been seeing articles in the media about current malware using stolen signatures and even being able to bypass the standard protection offered by Gatekeeper. These dangers can be thwarted more effectively by leveraging the power of high-performance protection software. The current test with 13 protection products for consumer users and corporate users shows which products have proven their worth. The packages need to fend off hundreds of MacOS malware samples and, at the same time, they need to make sure that no harmless applications and files are blocked. In addition, the test checks the extent to which the protection tools place a strain on the MacOS test systems. Many products are able to shine, scoring the highest points in the test.

A comparative assessment of Virtual Private Network (VPN) solutions was carried out in February 2025 by AV-TEST, commissioned by Kaspersky. This evaluation aimed to measure the performance of selected VPN services against unencrypted reference connections, as well as to review their included features, implemented security, IP protection capabilities, and the public transparency of the vendor behind the product.

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.
