Deep Vulnerability Assessment and Penetration Testing (OWASP + OT + IT Security included)
(i) Athena Dynamics + Cyberspace Command perform this via the Good Hackers Alliance. We do projects at $100,000 per month, depending on scope and the requirements of our client. We try to find bugs, weaknesses, vulnerabilities, backdoors/ trapdoors, hidden threats, zero day attacks, serious crimes, etc.
Usually, this helps find out where the gaps are--we recommend technologies or strategies to protect our client.
Please Google Good Hackers Alliance or request for case-studies/ reviews/ references from our team.
(ii) Consultants and our team perform certain services if decided there's need for this.
(iii) We have other teams ready to perform pen testing for you.
