FourCore ATTACK vs OpenAEV

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.

OpenAEV is an Adversarial Exposure Validation platform for creating cyberattack simulations, stress tests, and crisis exercises. Its breach and attack simulations draw on cyber threat intelligence and map scenarios to MITRE ATT&CK and ATLAS. Attack Chaining links actions into paths based on findings; teams can orchestrate these manually or use dedicated agents. Structured tabletop exercises are available for evaluating readiness, escalation, coordination, communication, and response. Adversarial Exposure Scoring tracks posture over time and maps coverage to MITRE ATT&CK and domain-based controls. The product lists more than 30 integrations and connections to OpenCTI, threat feeds, EDR/XDR, SIEM, and SOC playbooks. Deployment options include cloud, on-premise, and multi-tenant setups, with air-gapped and bring-your-own-cloud options listed for Enterprise Edition. Community Edition is free forever for on-premise core simulations and tabletop exercises, with community support. Enterprise Edition pricing is quote-based, and its SaaS trial lasts 30 days. Components are available as Docker images and manual installation packages; Kubernetes is recommended for production deployments.
