Spec score 7.8 #7 of 20 in Breach and Attack Simulation Software

What it is

FourCore ATTACK is an adversarial exposure validation platform that simulates cyberattacks to assess how security controls respond. Its threat intelligence connects current threats with an organization’s environment to help prioritize tests, and controlled campaigns emulate adversary tactics, techniques, procedures, indicators, and artifacts. Coverage includes endpoints, email, WAF, network segmentation, SIEM, EDR, XDR, firewalls, DLP, and exfiltration controls. Results map to MITRE ATT&CK techniques and classify outcomes as detected, partially detected, blocked, or missed. Campaign evidence can connect simulated behavior with control responses, telemetry, alert timing, and recommended next actions. Teams can generate or refine Sigma, YARA, Snort, and configuration changes, then retest after updates. Listed integrations include CrowdStrike, SentinelOne, Microsoft Sentinel, QRadar, Proofpoint, Cisco Secure Email, and ServiceNow. FourCore describes the product as AWS-hosted SaaS, with on-premises solutions available by discussion. Lightweight Windows and Linux agents connect to the SaaS platform. Simulations are designed not to disrupt or destroy target systems. Pricing is on request.
