MITRE Caldera vs SCYTHE

MITRE Caldera automates adversary emulation and routine cybersecurity assessments using the MITRE ATT&CK framework. Its listed uses include autonomous emulation, detection and response platform testing, manual red-team work, and red-versus-blue research. Adversary profiles can be used to exercise defenses and train blue teams. The core combines an asynchronous command-and-control server, a REST API, and a web interface; plugins add capabilities including Atomic Red Team techniques, operational technology support, ATT&CK visualizations, incident response, reporting, and training. Its default Sandcat agent is written in Go and supports cross-platform deployment, beaconing, instruction execution, payload downloads, and file uploads. Caldera is free, open source under Apache License 2.0, and intended for on-premises deployment. Installation is documented from source and through Docker, with full and slim container variants. The project lists Linux or macOS and Python 3.10 or later with pip as host requirements, and recommends at least 8 GB RAM and 2 CPUs for the core framework. It advises running Caldera in a secure environment or network because its web interface is not hardened or thoroughly penetration-tested.

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.
