- Horizon3.ai released Endpoint Security Effectiveness. Horizon3.ai added Endpoint Security Effectiveness to its NodeZero security platform, for evaluating the performance of EDR systems in live environments without disrupting operations. The new capability attempts to deploy a test RAT and assesses how the EDR handles the attack. One driver for the addition of Endpoint Security Effectiveness is the rise in credential-based attacks rather than attacks that exploit software vulnerabilities. A second is to give security teams much better metrics for assessing EDR efficacy. Available immediately. Horizon3.ai
