99.8% Real-World Protection: AV-Comparatives Ranks 16 Endpoint Security Products

For cybersecurity teams, the difference between a breach and a block often comes down to the endpoint agent. With Iranian-linked hackers and ransomware groups crippling global manufacturers this year, the latest AV-Comparatives Business Security Test provides a data-driven defense: real-world protection rates, false-alarm behavior, and performance impact across 16 products—so you can choose what actually stops the attack, not just what's marketed.

The first half of 2026 has jolted global enterprises with two stark reminders that endpoint compromise remains the gateway to operational catastrophe. In March, Iranian-linked threat actors breached medical device manufacturer Stryker and executed a mass factory-reset command that wiped more than 200,000 corporate devices across 79 countries, halting production and shipping for days. Two months later, Foxconn confirmed that the Nitrogen ransomware group stole approximately 8 terabytes of sensitive project data from its North American factories. Both incidents exploited weak endpoint security and third-party trust relationships, underscoring the urgent need for independently verified protection capabilities. Against this backdrop, the Austria-based testing institute AV-Comparatives has released the results of its Business Security Test for the March to June 2026 period, providing an authoritative real-world evaluation of 16 leading endpoint security products.

The 16 participants span the industry spectrum: Avast, Bitdefender, Cisco, CrowdStrike, Elastic, ESET, G Data, K7, Kaspersky, ManageEngine, Microsoft, Norton, SenseOn, Sophos, Trellix, and VIPRE.

The test is divided into multiple rigorous components. The Business Main-Test Series subjected each product to 400 real-world attack scenarios collected live from the internet during the testing period, simulating typical user web browsing and file exposure. It also measured each product's ability to detect pre-existing malware introduced via disk or network connections, as well as rates of false alarms on both common business applications and non-business software. A separate Malware Protection Test fed 1,000 recent malware samples to the products to gauge detection accuracy. Crucially, a Performance Test evaluated the system speed impact during everyday tasks such as file copying, archiving, launching applications, and web browsing—an often-overlooked factor that can slow business productivity if the security solution is too heavy.

The 16 participants span the industry spectrum: Avast, Bitdefender, Cisco, CrowdStrike, Elastic, ESET, G Data, K7, Kaspersky, ManageEngine, Microsoft, Norton, SenseOn, Sophos, Trellix, and VIPRE. The headline result is clear: absolutely no room for error against today's threats. In the real-world protection test, three products stood at the top: Kaspersky, Bitdefender, and Elastic each achieved a 99.8% block rate, missing only a fraction of the 400 test cases. That translates to effectively intercepting 399 out of 400 live attacks—a performance that would have prevented the Stryker-style lateral movement in many scenarios. In the dedicated malware detection test, Elastic raised the bar further with a perfect 100% score across all 1,000 samples, demonstrating deep threat intelligence and heuristic engines. Avast and Norton closely followed with 99.8% detection rates, indicating strong signature and behavioral analysis. While the press release highlights these top performers, it is equally noteworthy that some well-resourced enterprise-grade solutions did not achieve such flawless scores, a reminder that brand reputation alone cannot substitute for independent validation.

False positives are another battlefield. The testing confirmed that all products maintained low false alarm rates on business software, meaning IT teams won't be flooded with phantom alerts that waste time and erode trust. Similarly, the performance test revealed varying degrees of system footprint; although the exact rankings were not detailed in the summary, AV-Comparatives has long emphasized that the lightest solutions often surprise against heavyweight contenders. For organizations managing thousands of endpoints, a sluggish security agent can equate to millions in lost productivity, so performance is a critical tiebreaker.
