Mantis is a command-line framework designed to automate the workflow of asset discovery, reconnaissance, and scanning. It takes the top-level domains as input, then seamlessly progresses to discovering corresponding assets, including subdomains and certificates. The tool performs reconnaissance on active assets and concludes with a comprehensive scan for vulnerabilities, secrets, misconfigurations and phishing domains – all powered by a blend of open-source and custom tools.


  • Automated Discovery, Recon & Scan
  • Distributed Scanning (split a single scan across multiple machines)
  • Super-Easy Scan Customisation
  • Dashboard Support
  • Vulnerability Management
  • Advanced Alerting
  • DNS Service Integration
  • Integrate new tool (existing and custom) in minutes

Run a scan

You want to onboard an org with its TLDs/IPs/IP-CIDRs/IP Range for the first time, use the onboard mode. This runs the scan on the default workflow.


mantis onboard -o org_name -t   


mantis onboard -o org_name -t


mantis onboard -o org_name -t


mantis onboard -o org_name -t

Onboard Known Assets and Scan

mantis onboard -o org_name -f input.txt

Scan on all assets belonging to an organisation

Now that you have onboarded, you just need to run scheduled scans for an org, you can just use the scan mode

mantis scan -o org_name

Scan on all assets belonging to an organisation and app

 mantis scan -o org_name -a app_name
