Infection Monkey vs SCYTHE

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.

SCYTHE is a continuous Adversarial Exposure Validation platform for enterprise security teams. It runs MITRE ATT&CK-mapped adversary campaigns, including multi-stage campaigns based on named threat actors, to check whether controls detect, alert, block and respond. Results map to ATT&CK coverage and identified gaps. AI can generate campaigns from plain-language threat descriptions, but execution requires human approval. Deployment options include cloud SaaS, on-premises, hybrid and air-gapped environments. Listed integrations include CrowdStrike Falcon, Microsoft Defender, SentinelOne, Cortex XDR, Splunk, Microsoft Sentinel, IBM QRadar, Google Chronicle, Elastic SIEM, ServiceNow and Jira. SCYTHE says it connects bidirectionally with SIEM, SOAR, EDR, ticketing systems and security controls. Its tests are described as controlled, configurable, logged and auditable; destructive capabilities require explicit authorization. Included attack surfaces are Windows, macOS, Linux, cloud and OT/ICS. The company identifies itself as SOC 2 Type II certified and describes an annual independent security audit. Pricing is custom-quoted based on environment scope, and there is no free plan, though a free trial is available. Managed validation is also offered.
