Obtaining a security clearance is a critical step for individuals working in government, defense, cybersecurity, and other sensitive industries. However, not everyone who applies gets approved. Certain factors can disqualify an applicant, preventing them from accessing classified information.

In this guide, we’ll explore the most common security clearance disqualifiers, what can get you denied, and how you can overcome potential issues to improve your chances of success.


Common Security Clearance Disqualifiers

Not everyone qualifies for a security clearance. Various issues, from financial instability to criminal history, can lead to a denial. Below are the primary reasons why applicants get disqualified.

  • Provide explanations for financial difficulties if necessary.

Why It Matters:

  • A history of criminal behavior.
  • Suggests a risk to national security.
