The only perfect Endpoint Prevention and Response (EPR) score in 2026 belongs to Elastic

Elastic reports that its Elastic Security product was the only vendor to receive a perfect score in AV-Comparatives’ 2026 Endpoint Prevention and Response test, achieving 100% active prevention and passive detection across 50 multi-stage attack scenarios, with no false alerts or workflow delays among 14 tested vendors. The test used MITRE ATT&CK-based scenarios involving threats such as obfuscated scripts, fileless execution, AMSI bypasses, and USB-propagated payloads, and evaluated prevention, detection, operational accuracy, and user-impact costs. Elastic attributes its result to stopping all attacks during the initial compromise stage, before internal propagation or asset breaches occurred, arguing that early endpoint prevention reduces analyst workload and incident-response costs. The company also describes Elastic Defend’s cross-platform protections for Windows, macOS, and Linux, its support for ingesting third-party endpoint telemetry, and response and forensic features including LLM-assisted Attack Discovery, host isolation, and Osquery integration. Elastic further states that it has maintained perfect malware-protection results in multiple AV-Comparatives business security tests across 2025 and 2026 and has earned EPR Certified Leader status for two consecutive years.
