Listen: NISPOM Compliance When Your FSO Wears Multiple Hats
10:56

Executive Brief

At many small and mid-sized defense contractors, the Facility Security Officer (FSO) can also be the contracts manager, the HR director, or the program lead.

That reality does not change what the National Industrial Security Program Operating Manual (NISPOM) requires. It only changes how hard it is to meet those requirements consistently.

Part-time FSOs face the same compliance obligations as their full-time counterparts, including:

  • Maintaining Facility Clearance (FCL) and ensuring it stays current
  • Managing personnel security clearances from initiation through termination
  • Conducting annual security training and self-inspections
  • Overseeing Controlled Unclassified Information (CUI) and classified information handling
  • Staying current with Defense Counterintelligence and Security Agency (DCSA) guidance and Cybersecurity Maturity Model Certification (CMMC) developments

The stakes are high. A missed requirement, an expired document, or a failed DCSA Security Review can put your FCL and your contracts at risk.

Dig deeper below to learn more.

Why This Is a Growing Challenge in 2026

The number of cleared contractors has grown steadily, but most growth has come from small businesses, many of which cannot justify a dedicated, full-time FSO.

At the same time, NISPOM obligations have become more demanding, not less:

  • DCSA's Security Review and Rating Process (SRRP) framework means security reviews are more structured and consequential than ever
  • CUI handling and CMMC enforcement have tightened across the DIB, adding cybersecurity obligations that intersect directly with FSO responsibilities
  • Personnel security processes have grown more complex with expanded insider threat requirements

The part-time FSO model was never designed for this environment. Stretching a collateral-duty FSO across these expanding obligations creates risk, not just for compliance, but for the business.

What NISPOM Actually Requires of an FSO

NISPOM, formalized as 32 Code of Federal Regulations (CFR) Part 117 “The Rule”, establishes the framework for protecting classified information in contractor facilities. FSOs are responsible for implementing that framework, regardless of whether the role is full-time or collateral.

Core FSO responsibilities include:

  • FCL management: Maintaining the facility clearance, ensuring ownership and key management personnel records are current, and managing any changes that trigger DCSA notification
  • Personnel security: Initiating, monitoring, and closing out clearance actions for employees; managing visit requests; maintaining accurate personnel security records
  • Security education: Conducting initial and annual security awareness training; documenting completion; briefing employees on threat reporting obligations
  • Self-inspections: Conducting and documenting annual self-inspections aligned to DCSA's SRRP
  • Insider threat program: Administering the facility-level Insider Threat Program in compliance with NISPOM requirements
  • Incident reporting: Identifying, documenting, and reporting security incidents and suspicious contacts to DCSA
  • Physical security: Overseeing controlled access, open storage areas, and secure facility requirements where applicable

For a full-time FSO, this is a workload. For someone carrying a second or third role, it can be overwhelming.

Where Part-Time FSOs Commonly Fall Short

The most common compliance gaps are not the result of negligence. They are the predictable outcome of a model that asks too much of one person.

The most frequent issues include:

  • Lapsed training records: Annual security education requirements are missed or undocumented when the FSO has competing deadlines
  • Self-inspection gaps: Self-inspections are deferred, incomplete, or not tied to the SRRP framework DCSA uses during formal reviews
  • Clearance processing delays: Personnel clearance actions slip when the FSO cannot monitor status or respond quickly to DCSA requests
  • Outdated FCL documentation: Ownership changes, key management updates, or facility changes are not reported on time
  • Insider threat program drift: Program requirements are not kept current as DCSA guidance evolves
  • CMMC blind spots: FSOs without a dedicated cybersecurity partner often miss how their CUI responsibilities connect to CMMC obligations

We have written extensively on how FSO responsibilities now intersect with CMMC. The FSO's Guide to CMMC Readiness is a practical starting point for FSOs navigating both frameworks. 

What Happens During a DCSA Security Review

DCSA conducts Security Reviews on a risk-based cycle, but every cleared facility should be prepared for one at any time. The SRRP process evaluates your facility across multiple security areas, and findings directly affect your rating.

Reviewers will look at whether:

  • your self-inspection was completed and documented
  • security education records are current for all cleared personnel
  • clearance records are accurate and up to date
  • your insider threat program meets NISPOM requirements
  • physical security controls are in place where required
  • incidents and suspicious contacts were reported appropriately

A poor review outcome can result in a corrective action plan, a degraded facility rating, or in serious cases, suspension of the FCL. For a contractor dependent on cleared work, those outcomes are business risks, not just compliance findings.

Also, take our 2-minute Industrial Security Readiness Quiz to quickly gauge where gaps may exist before DCSA arrives.

The CMMC Intersection FSOs Cannot Ignore

The Department of Defense (DoD) (also known as the Department of War) has made CMMC a contract eligibility requirement for work involving CUI. That has direct implications for FSOs, even when cybersecurity is technically managed by IT.

FSOs are responsible for areas that connect directly to CMMC compliance:

  • CUI identification and handling: FSOs oversee how information is marked, stored, and protected, which must align to CMMC scoping requirements
  • Physical access controls: CMMC Level 2 includes physical protection requirements that FSOs typically own
  • Personnel security: Access controls and need-to-know determinations are part of both NISPOM and CMMC
  • Incident reporting: Both frameworks require timely identification and escalation of security incidents

Part-time FSOs who are not looped into the organization's CMMC program can create gaps that affect both assessment outcomes and contract eligibility.

For a deeper look at how CMMC functions as a business risk, not just a technical one, see: CMMC Is Not a Cyber Problem. It's a Business Risk Issue.

Options for Contractors Who Cannot Sustain a Full-Time FSO

Contractors operating with a collateral-duty FSO have several options for closing the gap between what is required and what one person can realistically manage.

Option 1: Structured Support from a Cleared FSO Partner

Outsourced or supplemental FSO support provides dedicated expertise without the cost of a full-time hire. A qualified FSO support partner can:

  • Serve as an Assistant FSO (AFSO) integrated with your internal team
  • Own specific compliance tracks like self-inspections or training administration
  • Monitor clearance actions and DCSA correspondence
  • Keep your FCL documentation current and audit-ready

Option 2: Invest in FSO Training and Tools

If the part-time FSO model is the right fit for your organization, investing in proper training and structured documentation processes reduces the risk of gaps. FSO training resources from DCSA, the National Classification Management Society (NCMS), and accredited providers help collateral-duty FSOs build baseline competency.

Documentation discipline matters as much as training. A well-maintained file structure and recurring calendar of FSO obligations goes a long way toward SRRP readiness.

Option 3: Build Toward a Dedicated FSO Role

For contractors whose cleared workload is growing, a dedicated FSO may be the right long-term answer. The question is how to manage compliance in the gap between where you are now and where you are headed.

FAQs

Can a part-time FSO realistically meet all NISPOM requirements?

It depends on the scope of your cleared program. For facilities with a small number of cleared employees and limited program activity, a well-organized collateral-duty FSO can manage the workload. As the program grows, the risk of gaps increases significantly. Structured support from an experienced FSO partner is often a cost-effective way to maintain compliance without a full-time hire.

What happens if our facility fails a DCSA Security Review?

DCSA will typically issue findings and require a corrective action plan. Depending on severity, your facility rating may be affected. In cases of serious or repeated deficiencies, DCSA can suspend or revoke the FCL, which directly impacts your ability to hold and perform on cleared contracts.

Do FSO responsibilities change under CMMC?

CMMC does not replace NISPOM, but it adds an overlapping layer of requirements that FSOs need to understand. Physical protection, CUI handling, and access control areas that FSOs typically manage are also assessed under CMMC Level 2. FSOs who are not aligned to their organization's CMMC program can inadvertently create compliance gaps in both areas.

When should we consider outsourced FSO support?

When your collateral-duty FSO is consistently unable to complete required activities on time, when your cleared program is growing faster than your internal capacity, when you are approaching a DCSA review with documentation gaps, or when you are simultaneously navigating CMMC compliance, these are all signals that supplemental support is worth evaluating.
