The pentest operations platform that turns recon, CLI work and findings into a report as you go
Nmap and other scan output is parsed into structured hosts, ports and services, keeping a single source of truth instead of spreadsheet soup.
Describe an objective and the agent assembles the right command, runs it on a connected machine and drops structured results back into the project.
CredCruncher and leak/exposure signals check discovered secrets against breach-sized datasets, while OSINT is mapped geographically and relationally in one canvas.
Smart Notes automatically associate with the host, person or credential they describe, and evidence stays attached to the findings it supports.
