The only perfect Endpoint Prevention and Response (EPR) score in 2026 belongs to Elastic
Summary
Elastic Security achieved a perfect 100% score in AV‑Comparatives’ 2026 Endpoint Prevention and Response (EPR) test, stopping all 50 attack scenarios at the prevention stage with zero false positives or workflow delays. The test measured active prevention, passive detection, operational accuracy, and workflow impact across 14 vendors. Elastic’s claim is backed by open‑source protection rules and…
- AV‑Comparatives EPR 2026 runs 50 multi‑phase attack scenarios based on MITRE ATT&CK tactics, covering executables, scripts, Office add‑ins, USB payloads, obfuscation, AMSI bypasses, and fileless techniques.
- Elastic scored 100% on both Active Response (prevention) and Passive Response (detection) and reported zero operational accuracy costs or workflow delays, the lowest total cost of ownership among 14 vendors.
- The product’s prevention rules are published in an open GitHub repo, and Elastic can ingest third‑party endpoint telemetry to provide unified detection and response.
- Elastic’s Attack Discovery feature leverages a user‑chosen LLM to summarize alerts into an attack narrative, and the platform integrates with Osquery for live host queries.
Endpoint prevention that blocks attacks before execution can dramatically reduce alert fatigue, investigation time, and overall incident cost. A zero‑false‑positive score suggests that Elastic’s rules may be tuned to avoid the common trade‑off between detection coverage and operational noise, which…
