Founded in 2010 by Cale Dansbee, TOPSTONE is a Service-Disabled Veteran-Owned cyber security consulting practice based on 20 years of information technology experience inside the U.S. Federal government. Cyber security is in our DNA and in everything we do.

Our managed security services are scratch built and based on decades of experience with government agencies, policy, laws, and industry standards. Our core areas of expertise are:

  • DFARS Compliance
  • Risk Mitigation
  • Security as a Service (SECaaS)
  • Firewall as a Service (FWaaS)
  • Vulnerability Assessment
  • Compliance Auditing

All of our services have been engineered to provide you with a comprehensive, yet simple to implement security strategy that can have even small businesses operating using the same methods, procedures, and technology as NASA and other Federal agencies.

Relationships and client satisfaction are among our most valuable pillars. We pride ourselves on treating each client as if they are our only client.


Located in sunny San Diego, California, our office is a fun place to be and a great place to drink coffee and solve problems.
