Nighthawk Security was founded in 2003 and has operated for over 20 years, and we’re bringing that same personalized approach to businesses throughout St. Augustine, Ponte Vedra, Ponte Vedra Beach, Nocatee, and the rest of St. Johns County. We hold Florida alarm contractor license EF20001962. We discuss your company’s needs and budget, and then custom design the security solution for you, rather than fitting your business into a generic package.
Retail, office, and multi-location businesses across St. Johns County all face different risks. A historic St. Augustine storefront faces different loss-prevention pressure during tourist season than a Ponte Vedra office does. We start by understanding your property, your hours, and your busiest seasons, then design a plan from four core systems.

Intrusion detection covers doors, windows, and interior motion, the baseline layer for any commercial account.

Commercial fire monitoring ties into the same central station watching your intrusion alarm, so a fire hazard gets a response even after hours.

Access control replaces or supplements traditional keys with keycard, fob, or code-based entry, letting you manage who gets into which parts of your building and when.

Video surveillance gives you visual verification alongside sensor-based detection, with footage reviewable remotely, useful for an owner managing a location they can’t visit daily.
We help you decide which of these your St. Johns County business actually needs.
When a sensor at your business triggers, a trained operator reviews the alert and works through your account’s call list before contacting local law enforcement or fire services directly. Our monitoring is backed by redundant centers in Florida, New Jersey, and California, so a regional outage at one center does not take your monitoring offline.
We hold a BBB A+ rating, and we are fully insured and bonded. We have over 20 years of experience, and St. Johns County is part of our newer Florida expansion, backed by the same monitoring standards we’ve used from the start.
We provide commercial security in St. Augustine, Ponte Vedra, Ponte Vedra Beach, Nocatee, and the surrounding area. Contact us with your business address to confirm coverage.

Commercial installation starts at $499. Burglar alarm monitoring starts from $37.95 per month plus tax, and accounts with fire alarm monitoring start from $57.95 per month plus tax. Actual costs vary with property size and equipment needs, and our team will walk the site before finalizing a quote.
