Expert Compliance Consulting
Backed by Cleared Systems
Computer Security Services US was built on a single principle: every organization deserves access to world-class compliance expertise, regardless of size. As a division of Cleared Systems, LLC, we bring the full depth of federal compliance knowledge to healthcare organizations, defense contractors, and federal agencies across 200+ U.S. cities.
We have trained over 50,000 healthcare professionals, published 16+ books on cybersecurity and compliance including the full CISSP domain series, and supported hundreds of federal contractors through CMMC, ITAR, and CUI program implementation.
Unlike generalist IT firms that dabble in compliance, Computer Security Services US lives and breathes federal and healthcare regulatory frameworks. Our team's credentials span CISSP certification, CMMC-AB registration, ITAR program management, and HIPAA privacy officer experience — all under one roof.
We only do compliance. No generalist IT distractions — pure regulatory expertise across HIPAA, CMMC, ITAR, CUI, and vCISO.
Rare ability to handle HIPAA + CMMC + ITAR + CUI simultaneously — most firms can only address one framework at a time.
As a Cleared Systems division, we bring federal contracting depth, credentialing resources, and established agency relationships.
50,000+ professionals trained, 16+ published books, 25 years of results — a track record that speaks for itself.
