Cymulate Platform vs Infection Monkey

Cymulate Platform continuously validates security controls against real-world threats and provides guidance for improving defenses. Its modules include Exposure Validation, Auto Mitigation, CTEM, Detection Studio, Threat Studio, and Cymulate Cowork. Cymulate says its threat library covers MITRE ATT&CK and that new simulations for US-CERT advisories have a 24-hour SLA. Vero AI tailors threat assessments to a customer’s environment, helps prioritize findings, and supports mitigation creation. Listed partners include AWS GuardDuty, CrowdStrike, Splunk, and Anthropic Claude. The platform is designed for security operations, detection engineering, red teams, and exposure management teams, including mid-market and enterprise organizations. A free trial provides partial platform simulation for 14 days unless a quote specifies another period; pricing is on request and depends on package, assets, and scenarios. Cymulate says the platform runs on a private AWS tenant across multiple regions. It lists security certifications and compliance frameworks, protects traffic with TLS 1.2 or higher, and encrypts stored data with AES-256. Customers must provide equipment, infrastructure, servers, and third-party software or licenses required by the platform prerequisites.

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.
