Why FSO Services Matter
If your organization holds or is applying for an FCL, you’re required to have an active FSO responsible for maintaining classified contracts, personnel security, and facility compliance. But for many small businesses, the workload doesn’t justify a full-time position — and that’s where we come in.
Outsourcing your FSO duties gives you:
Cost-effective support from seasoned professionals
Time back for your core business and mission-critical work
Peace of mind that your program meets federal expectations

Who This Is For
Small to mid-sized contractors with an active or pending FCL
Cleared organizations that need part-time or interim FSO support
Teams who want help with audits, documentation, or compliance tasks
Companies that need an experienced AFSO while keeping overhead low
