Elastic is positioning its security portfolio to counter the accelerating velocity of AI-driven cyberattacks by prioritizing early-stage prevention over reactive detection. The company announced that Elastic Security earned "Certified Leader" status in the AV-Comparatives 2026 Endpoint Prevention and Response (EPR) Test, marking the second consecutive year it has received this distinction. Among 14 vendors tested, Elastic was the only provider to achieve a perfect protection score, blocking all 50 multi-phase attack scenarios at the initial phase of compromise without generating false positives.
Elastic Security Performance in EPR Testing
The AV-Comparatives EPR Test 2026 evaluated 14 vendors using 50 multi-phase attack scenarios derived from the MITRE ATT&CK framework. These scenarios tested diverse vectors, including fileless execution, AMSI bypasses, EDR unhooking, and USB-propagated payloads. Elastic Security distinguished itself by achieving 100% scores in both Active and Passive Response categories. Crucially, the company reported that its solution stopped every threat during the first stage of the attack chain—covering Initial Access, Execution, and Persistence—preventing any movement into Internal Propagation or Asset Breach. This performance occurred alongside one of the lowest modeled operational footprints and total costs of ownership (TCO) among the participating vendors. By neutralizing threats at the endpoint before they escalate, the company aims to reduce the investigative burden on security operations centers.
Addressing AI-Driven Attack Velocity
The technical focus of this year's testing reflected a shift in the threat landscape, incorporating AI-assisted development methods to simulate modern attacker tooling. Elastic is framing its prevention capabilities as a necessary response to adversaries using automated toolchains to compress attack timelines. According to Mike Nichols, general manager of Security at Elastic, these automated methods allow attackers to move from initial access to data exfiltration in minutes rather than hours. The company suggests that traditional detection and response models may struggle to keep pace with this machine-speed movement. By stopping threats at the first phase of compromise, Elastic Security intends to prevent the escalation of incidents that would otherwise require manual triage. The Elastic Defend product, which powers these results, remains available across Windows, macOS, and Linux in cloud, on-premise, hybrid, and air-gapped environments.
Key Takeaways
- Elastic Security was the only vendor to block and report all 50 tested attack scenarios at the first phase of compromise.
- The product achieved 100% Active and 100% Passive Response scores in the AV-Comparatives 2026 EPR Test.
- Elastic reported one of the lowest total costs of ownership (TCO) and the lowest modeled operational footprint among the 14 tested vendors.
TechInsyte's Take
In our view, Elastic’s performance in the 2026 EPR test highlights a critical strategic pivot in the endpoint security market: the move from "detect and respond" to "prevent at the edge." As AI-driven automation allows adversaries to bypass traditional human-speed response windows, the ability to stop an attack during the Initial Access or Execution phase is no longer just a feature—it is a requirement for resilience. By securing a perfect score while maintaining a low operational footprint, Elastic is signaling to enterprise buyers that high-efficacy prevention does not have to come at the cost of massive resource consumption or high TCO.
