FourCore ATTACK vs Infection Monkey

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.

Infection Monkey is an open-source breach and attack simulation tool for checking data center resilience to perimeter breaches and internal server infection. Monkey Agent scans systems and simulates attack techniques, while Monkey Island Server provides a command-and-control web interface. The tool maps visible machines, accessible services, and possible routes through a network, then reports security issues the agents discover or exploit. It supports on-premises environments, containers, and public and private clouds. The documented AWS integration uses Systems Manager to run Infection Monkey on EC2 instances, and plugins can be installed, updated, removed, or uploaded through the Monkey Island interface. Internet access is not required; when available, it is used to check for updates and whether machines can reach the internet. The FAQ says sensitive data is encrypted in the Island database and sent to agents over HTTPS, and that first launch requires creating credentials for access to the server. It also says the tool avoids exploits or attacks that may affect target systems, including EternalBlue. The Free plan is free.
