Chris Williams

Expert in Cybersecurity strategy

I have been involved in the IT security field since 1994 with a combination of commercial and military positions.

I joined Capgemini through its acquisition of Leidos Cyber in 2018, and currently focus on enterprise cybersecurity, defense against advanced threats, and regulatory compliance strategy.  I have advised commercial clients in the Financial, Industrial, Energy, and other critical infrastructure industries, and also hold a patent for secure e-commerce technology.

I regularly advise my clients on advanced cyberdefense topics including Advanced Persistent Threat, nation-state adversaries, Identity and Access Management, and cloud solutions using SaaS, IaaS, and PaaS technologies.  I have also performed cybersecurity assessments using the NIST CSF, FISMA, FedRAMP, HIPAA, FFIEC, CSC-20, and other frameworks.

I am a frequent public speaker and have presented on cybersecurity topics at RSA, MILCOM, HIMSS, (ISC)2, ISSA, the Smart Card Alliance, B-Sides and other forums.

I have co-authored four books on cybersecurity:

  • Enterprise Cybersecurity: How to Build a Successful Cyberdefense Program (Apress)
  • Enterprise Cybersecurity Study Guide (Apress)
  • Understanding Security Issues (de Gruyter)
  • Building an Effective Security Program (de Gruyter)

I am also a former Ranger-qualified paratrooper with the 82nd Airborne Division, and hold degrees in Computer Science and Information Assurance.
