Core impact: With over 20 years in the market, Core Impact claims the largest range of exploits available in the market, they also let you run the free Metasploit exploits within their framework if they are missing one. They automate a lot of processes with wizards, have a complete audit trail including PowerShell commands, and can re-test a client simply by re-playing the audit trail.
Core write their own ‘Commercial Grade’ exploits to guarantee quality and offer technical support around both those exploits and their platform.
They claim to be the market leader and used to have a price tag to match. More recently the price has come down and they have models appropriate for both corporate and security consultancies.
