Prancer delivers autonomous penetration testing and continuous attack validation for enterprises, MSPs and public-sector teams. Its SwarmHack engine is a swarm of specialized AI agents with 100+ capabilities across 85 plugins. It plans its own attack path, exploits web applications, REST and GraphQL APIs, networks, Active Directory, cloud, containers and CI/CD, then moves laterally, escalates privileges and captures crown jewels. Unlike scanners and breach-and-attack simulation, Prancer validates rather than predicts. Critical severity is reserved for proven exploitation, and every result ships as an evidence-graded report inside a signed authorization envelope. Prancer also tests whether deployed defenses, such as segmentation, Zero Trust, SASE/SSE and identity controls, actually stop the attack. It covers new surfaces such as AI agents, non-human identities, IoT and OT. A deterministic core runs reproducibly and air-gapped, with optional frontier or sovereign models. Compliance evidence maps to SOC 2, ISO 27001, PCI DSS 4.0, HIPAA, DORA and NIS2.
