5 Best Security Guard Companies in New York (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Fenris Morrow, Expert in Professional Services · ✓ Data verified August 2026 · 8 min read

Hiring security for an event or a building means trusting a company you may never meet in person until the guards show up. New York's top-rated security guard companies have logged over 8,600 Google reviews between them, and one name alone accounts for the overwhelming majority, so knowing what each business actually specializes in matters more than the star rating alone.

Short answer: Guardian Group Services dominates on volume with 8,158 reviews at 4.9 stars, though most of that feedback centers on its security guard licensing and training courses rather than deployed guard services. For companies that staff and deploy guards, Yellowstone Security Services (5.0 stars, 119 reviews) and Security USA (4.2, 245 reviews) are the strongest picks for events and buildings respectively.

Watch: 5 Best Security Guard Companies in New York (2026)

How we score

Every number on this page comes from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other New York security companies. Confidence weighs the rating by that volume, so a 4.9 from over eight thousand reviewers carries more weight than a 5.0 from a smaller sample. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does security guard staffing cost in New York? (2026)

None of the companies on this list published a clear standard rate card at the time of writing. Pricing for guard services depends heavily on the number of guards, event length, and whether armed or unarmed coverage is needed. Ask each company for a written quote based on your specific event or site.

Serving all of New York

These companies cover the New York City boroughs, with several based in Brooklyn and Manhattan and coverage extending into surrounding counties like Nassau, Suffolk and Westchester. Searching for security guard companies near me? Every listing below shows a live phone number and directions so you can reach the closest option fast.

What to ask before you hire a security guard company

Are your guards licensed and insured in New York State?
Is this quote for licensed, deployed guards, or is your business primarily training-focused?
How far in advance do you need notice for an event booking?
Can you provide references from past clients with a similar type of event or building?
What’s included in the quote (guards, supervision, equipment, transportation)?

Frequently asked questions

How did you choose these security companies?

We started from every security guard company in New York with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

Do these companies offer guard staffing or just training?

Most offer both, but the balance differs. Guardian Group Services’ review base skews heavily toward training and licensing courses; confirm directly if you specifically need deployed guard staffing.

Which company is best for a one-time event?

Yellowstone Security Services and Stone Security Services both specialize in private events, the former for general functions and the latter for high-profile occasions like Fashion Week.

The bottom line

Guardian Group Services leads on sheer review volume, though much of that feedback is about its licensing courses rather than guard deployment, so confirm which service you need before you call. For hiring actual guards, Yellowstone Security Services and Security USA are the more directly relevant picks for events and buildings respectively.
