What Is a Security Clearance?
A security clearance is required for individuals working with classified information in federal agencies, defense contracting, or intelligence-related positions. Whether you're a government contractor, military personnel, or federal employee, holding a clearance confirms you can be trusted with sensitive data.
Clearances are granted after a comprehensive background investigation, including a criminal history review, financial background check, and foreign contact screening. Agencies such as the Defense Counterintelligence and Security Agency (DCSA) handle investigations to protect national security.
Failure to comply with clearance requirements can lead to revocation, job loss, fines, or even imprisonment. Understanding the clearance process—and how to maintain eligibility—can help you secure long-term federal contracting opportunities.
Confidential
The lowest level of clearance covers information that could cause damage to national security if disclosed. Common for administrative and support roles. Under the traditional periodic reinvestigation model, reinvestigation was required every 15 years. However, under the Trusted Workforce 2.0 initiative, continuous vetting is replacing periodic reinvestigations across all clearance levels.
Secret
Covers information that could cause serious damage if leaked. Requires a deeper background check than Confidential. Common among military personnel, intelligence officers, and defense contractors. Previously required reinvestigation every 10 years, but this is being replaced by continuous vetting under Trusted Workforce 2.0.
Top Secret (TS)
Grants access to data that could cause grave damage to national security. Requires a comprehensive investigation. Held by high-ranking government officials, intelligence professionals, and national security personnel. Previously required reinvestigation every five years, now transitioning to continuous vetting.
Sensitive Compartmented Information (SCI) and Special Access Programs (SAP)
SCI grants access to intelligence-related data and may require polygraph testing. SAP is used for covert operations and classified defense projects. Both require extra approvals, strict monitoring, and ongoing security training.
Mishandling SCI or SAP information can lead to criminal charges under the Espionage Act (18 U.S.C. 793 through 798).
What Is Continuous Vetting (and Why It Matters for Contractors)
The federal government is in the middle of a major shift in how security clearances are monitored after they are granted. Under the Trusted Workforce 2.0 initiative, the Defense Counterintelligence and Security Agency (DCSA) is replacing the old model of periodic reinvestigations every 5, 10, or 15 years with continuous vetting (CV).
Continuous vetting uses automated checks against criminal, financial, terrorism, and public records databases on an ongoing basis rather than waiting years between reviews. As of early 2026, over 3.8 million cleared personnel are enrolled in continuous vetting, and DCSA is expanding the program to include non-sensitive public trust positions as well.
What this means in practice: clearance holders are being monitored in near real time. Financial issues, arrests, foreign contacts, and other potentially disqualifying events are flagged as they happen rather than discovered years later during a reinvestigation. DCSA has described the program as a way to identify and address issues early rather than as a punitive system.
For contractors, this changes the landscape in a few ways. Cleared employees need to understand that self-reporting obligations are actively enforced through automated monitoring. Companies holding facility clearances should ensure their security officers are briefing staff on CV requirements. And contractors bidding on work that requires cleared personnel should factor in that the vetting process, while still lengthy for initial investigations, is getting faster. DCSA reported its initial investigation backlog dropped to approximately 100,000 cases in January 2026, down 65 percent from the start of 2025.
Current governmentwide processing targets are 40 days for Secret clearances, 75 days for Top Secret, and 25 days for public trust positions. Actual timelines vary, but the trend is toward faster processing as the backlog continues to decrease.
1. Find a Sponsoring Employer
- Individuals cannot apply for clearance independently.
- A federal agency or approved contractor must sponsor the application.
- Sponsorship is based on job duties requiring classified access.
2. Undergo a Background Investigation
Conducted by the DCSA, this includes:
- Criminal history review
- Financial background check (credit score, bankruptcy, debt history)
- Foreign contacts and travel history
- Drug use history
- Employment and education verification
- Interviews with associates and former employers
As of 2025, DCSA transitioned to updated versions of the Standard Forms (SF-86 and related forms) through the eApp electronic application system. Previous versions of these forms are no longer accepted. The Personnel Vetting Questionnaire (PVQ), which was planned as a replacement for the Standard Forms, has been delayed and is not yet in use. For now, applicants should expect to complete the current SF forms through eApp.
Candidates with substantial debt, foreign ties, or past drug use may face delays or disqualification.
3. Clearance Adjudication & Approval
- Officials review findings under 13 adjudicative guidelines, including loyalty, financial responsibility, and personal conduct.
- If concerns arise, applicants may need to provide additional documentation.
- Clearance is not guaranteed and can be denied or revoked based on investigative results.
- Appeals are possible—candidates can present mitigating evidence to contest denials.
4. Maintaining Clearance Eligibility
Security clearance holders must follow strict reporting requirements, including:
- Foreign travel and interactions with foreign nationals
- Major financial changes (bankruptcy, large debts, unpaid taxes)
- Legal issues that could impact trustworthiness
Continuous Evaluation (CE) allows agencies to monitor real-time security risks, ensuring immediate updates to clearance status.
The 2026 National Defense Authorization Act also introduced changes relevant to clearance holders. The legislation extends how long departing DoD personnel remain eligible for classified access to up to five years, up from the previous 24-month window. This means service members and DoD civilians who leave government can maintain their clearance eligibility longer, which is significant for contractors hiring from the federal workforce. The NDAA also includes provisions allowing companies to build a deeper bench of staff for classified programs while employees are still in the clearance process.
Handling Classified Information: Your Responsibilities
A security clearance is a privilege, not a right. Mishandling classified documents can lead to criminal charges, job loss, and fines.
Common security violations include:
- Discussing classified details in unsecured locations
- Failing to store sensitive documents properly
- Using personal devices for classified communication
With cybersecurity threats on the rise, clearance holders must follow IT security policies, including:
- Using government-approved communication channels
- Avoiding unsecured networks
- Completing routine security training
Failure to comply with security protocols can result in suspension or revocation of clearance.
Security Clearance Transfers & Reciprocity
If you change jobs within the government or switch federal contractors, clearance reciprocity allows approved clearances to transfer without restarting the investigation.
However, different agencies may have additional screening requirements, which could cause delays.
Understanding reciprocity policies can help minimize processing times and job transition issues.
