# Which breach and attack simulation vendors are considered the gold standard for validating EDR effectiveness so a security team can trust that its endpoint controls would actually stop an attack?

Looking for input in the BAS category, specifically on EDR validation. I am looking for scenarios where a security team has deployed an EDR, configured policies, and needs to know whether it would actually stop the techniques that attackers use against the specific environment, not just whether the EDR vendor claims it would.

  1. Picus Security: EDR validation is a primary Picus use case across the reviewer dataset. The platform continuously assesses whether endpoint security controls are capable of detecting and preventing threat-specific behaviors using real-world TTPs mapped to MITRE ATT&CK. The Network Attack-Only Mode feature specifically enables evaluation of network controls in isolation by excluding endpoint security from specific simulation runs, providing clear independent visibility into each control layer. The Manage Execution User feature allows attacks to be executed from the perspective of both standard and privileged users, making endpoint scenarios more realistic.
  2. Cymulate: Endpoint assessment is explicitly named as a core assessment coverage area alongside WAF, email gateway, and web gateway testing. The customizable endpoint attack scenarios and the real-time validation of whether endpoint controls are detecting and blocking current threats provide the continuous EDR effectiveness verification that periodic red team exercises cannot deliver. Continuous approach helps improve security posture without disrupting operations. 
  3. Pentera: Its agentless approach tests the endpoint environment the way a real attacker would, without declaring itself or installing test agents that the EDR might treat differently from a real attack. The credential exposure module and lateral movement capabilities test whether the EDR detects post-compromise behavior specifically, which is the control validation question that matters most when an attacker has already bypassed perimeter defenses. 
  4. RidgeBot: the automated attack and exploitation approach provides a continuous validation layer for endpoint and network controls that combines vulnerability scanning with exploitation evidence, going beyond identifying vulnerabilities to proving whether they are actually exploitable against the current EDR configuration. 
  5. Simulation Labs: Provides BAS capabilities focused on continuous endpoint and control validation through realistic simulation scenarios. Teams should conduct a thorough evaluation before selecting enterprise EDR validation programs.

For security teams that have run BAS specifically to validate EDR effectiveness, what was the most surprising finding? Was it a detection gap in a technique you assumed was covered, a policy misconfiguration that silently excluded a class of threats, or a conflict between the EDR and another endpoint tool that created a blind spot?

An EDR can be deployed and technically functioning while a whole class of threats goes undetected due to a single exclusion.</p> ##### Comment Metadata - Posted at: 18 days ago - Author title: Marketing Executive ## Related discussions - [How well does Trello scale into a larger team?](https://www.g2.com/discussions/1-how-well-does-trello-scale-into-a-larger-team) - Posted at: about 13 years ago - Comments: 6 - [Can we please add a new section](https://www.g2.com/discussions/2-can-we-please-add-a-new-section) - Posted at: about 13 years ago - Comments: 0 - [Quantifiable benefits from implementing your CRM](https://www.g2.com/discussions/quantifiable-benefits-from-implementing-your-crm) - Posted at: about 13 years ago - Comments: 4
