CST Verdict

Based on our analysis of core features, here is our conclusion:

Caldera

Security teams building an adversary emulation program on a shoestring budget should start with Caldera; it's the only free framework that lets you automate attack chains against your own infrastructure without vendor lock-in. MITRE's backing means the technique mappings to ATT&CK are authoritative, and you get a real agent-based architecture that scales across hundreds of endpoints. Skip this if you need a polished UI or managed red team operators; Caldera requires security staff who are comfortable with YAML configurations and Python customization to extract value.
