The best thing about lotan was that it helped us to understand our customers better by analyzing their data from various sources which were not available with other tools in market like pentest-aspen etc., Also we could easily identify potential threats using this tool.
It's too expensive for small companies/organizations as compared to other free alternatives out there but still its worth trying if you are looking into some specific areas of your organization where threat intelligence can help improve things. We have been able to find new vulnerabilities in existing applications used internally within our own environment without any third party penetration testing or vulnerability assessment services required.
