Independent by design.

Capstone Security is an information security consulting firm founded in 2000. For more than twenty-five years we've helped clients protect critical data, harden applications, maintain compliance, and reduce overall risk, across organizations from large enterprises to small operations.

We are an independent consultancy. We don't sell products and we don't earn vendor commissions, so our only incentive is to give you an accurate answer. Every engagement is led by senior consultants and draws on thousands of completed assessments across compliance, security, and engineering work.
