Cerno

Cerno helps security professionals review Nessus vulnerability findings and orchestrate verification tools from a terminal interface. The name comes from the Latin cernō: to discern or sift through.

Cerno maintains organized databases at ~/.cerno/cerno.db, making it easier to track findings and workflow state across sessions.

Use Cerno when you need to:
  • Turn vulnerability scan output into a repeatable verification workflow
  • Keep assessment findings organized across multiple review sessions
  • Launch follow-up commands without losing context
  • Interactive keyboard-driven workflow
  • SQLite persistence across sessions
  • nmap NSE, NetExec, and custom command orchestration
  • CVE extraction and Metasploit module searches
  • Large-scale vulnerability assessment organization
  • Remediation tracking and post-exploitation intelligence correlation
pipx install git+https://github.com/ridgebackinfosec/cerno.git

CLI Utilities

Auxiliary

Auxiliary is a collection of dependency-free Python utilities for reconnaissance, list processing, firewall management, and local operational tasks during security assessments.

Tools are available through a unified auxiliary <tool> CLI or individual commands with aux- prefixes.

Use Auxiliary when you need to:
  • Clean up targets, IPs, credentials, or tool output quickly
  • Run small assessment helpers without extra dependencies
  • Standardize repeatable local operator tasks
  • DNS tools and domain controller discovery
  • IP extraction and target list normalization
  • Gobuster output conversion
  • Nessus scope and utility workflows
  • Firewall management with dry-run and backups
  • Credential splitting, chunking, and other file processing helpers
  • Dependency-free scripting and automation support
pipx install git+https://github.com/ridgebackinfosec/auxiliary.git
