Cybersecurity Consulting
Expert guidance. Vendor-neutral advice. Risk-based decisions.
We help you choose what is right, not what is expensive.
Most security 'consultants' are actually product resellers in disguise. CSIS is a pure-play advisory firm. Our only incentive is your security. We help you navigate the complex vendor landscape to build a lean, effective, and defensible security posture.
