Security is one of the most-hired professions in the United States. Over 1 million security guards work across the country. And most of them land jobs through agencies that process hundreds of applications per week.
Your cover letter is what gets you pulled from the pile.
The templates below are designed for the three most common security career paths: unarmed guard, armed guard, and security supervisor. Pick yours and customize it.
“Security companies don’t care about your muscles. They care about your paper. License, certification, clean background. Mention all three in your cover letter or don’t bother applying.” — StylingCV Career Team

4 Security Cover Letter Mistakes
| Mistake | Fix |
|---|---|
| No license or cert mentioned | Put your guard card number and certs in the first paragraph |
| Too aggressive tone | Professional, calm, and confident — not “tough guy” |
| No mention of report writing | Security is documentation. Prove you can write. |
| Vague availability | Say exactly which shifts you can work. Overnight availability = hired faster. |
