What is Military Security Clearance & What Does it Reveal About a Veteran Job Candidate?
The U.S. government protects classified information that could threaten national security if released without authorization. Because of this, only individuals with the appropriate eligibility and access can work with certain information, systems, or facilities.
For veterans, a current or previously held security clearance can also be valuable when pursuing civilian careers in defense, intelligence, cybersecurity, engineering, information technology, and federal contracting.
Quick Answer: What Is a Security Clearance?
A security clearance is a determination that someone is eligible to access classified national security information. The three primary levels are Confidential, Secret, and Top Secret.
How Does Someone Obtain a Security Clearance?
Individuals generally cannot apply for a security clearance on their own. A military organization, federal agency, or cleared employer must sponsor someone for a position that requires access to classified information.
The investigation evaluates whether the individual is eligible to access classified information based on federal personnel-vetting standards.
What Are the Levels of Security Clearance?
Confidential
Unauthorized disclosure could cause damage to national security.
Secret
Unauthorized disclosure could cause serious damage to national security.
Top Secret
Unauthorized disclosure could cause exceptionally grave damage to national security.
Some information requires additional access controls, including Sensitive Compartmented Information (SCI) or Special Access Programs (SAP).
How Does the Security Clearance Process Work?
The individual is selected for a position requiring classified access and is sponsored for the appropriate investigation.
Records, employment history, finances, criminal history, foreign contacts, and other relevant information may be reviewed.
The information gathered is evaluated under federal guidelines to determine eligibility for classified access.
What Can Affect Security Clearance Eligibility?
Clearance decisions use a whole-person approach. One concern does not automatically mean someone will be denied.
Which Military Members Need a Security Clearance?

Why Should Employers Recruit Veterans With Security Clearances?
For positions requiring classified access, recruiting veterans with relevant clearance eligibility can help support a more efficient hiring process.
Veterans may also bring technical expertise, leadership experience, and familiarity with highly regulated environments. Understanding the military experience behind a resume can help employers identify qualifications that may not be obvious from a military job title alone.
What Does a Security Clearance Tell a Recruiter?
A current or previously held clearance tells an employer that the veteran completed a federal personnel-vetting process and received an eligibility determination for access to classified information.
A clearance should not replace an employer’s normal hiring process, but it can provide valuable context when recruiting for cleared or national-security-related roles.
