Hands-on NIST SP 800-171 assessment experience

In 2021, while at Data-Tech, James served as IT Lead, Integrator, and Director of Compliance Management for an official Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) assessment.

The assessment found 108 of 110 NIST SP 800-171 security requirements met.

Working with controlled information

James's background includes work involving controlled unclassified information (CUI), International Traffic in Arms Regulations (ITAR), and EAR99 classifications under the U.S. Export Administration Regulations.

That assessment and operational experience informs Castilix's approach to readiness: define the environment, assign responsibilities, and connect documented requirements to implementation and evidence.
