- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
