There are over 100 security guard companies in San Diego County. Some are great. Some will get you sued. Here is how to tell the difference — written by a retired Chula Vista PD officer who has been doing this since 2002.
First: Verify Their License
Every security guard company in California needs a Private Patrol Operator (PPO) license from the Bureau of Security and Investigative Services (BSIS). No exceptions. No 'pending licenses.' No 'we are part of a national company.'
Look up any San Diego security company at the California BSIS license lookup. If they are not listed, walk away.
Pro tip: Ask for the PPO number in writing. A real company gives it to you on the spot. A fake one stalls or changes the subject.
Second: Check Their Insurance
A real security company carries three insurance policies:
- General liability ($1 million minimum, $2 million for serious work)
- Workers' compensation (for every guard on your property)
- Errors and omissions (for PI work)
Ask for a Certificate of Insurance (COI) with your name listed as an additional insured. A real company sends it the same day. If they hesitate or say 'we will get back to you,' that is a red flag.
Third: Ask About Their Guards
This is where bad companies fall apart. Ask:
- Do you do background checks? Federal and state, not just one.
- How much training do your guards get? California requires 8 hours of basic plus 32 hours within 6 months. Good companies do much more.
- Are your guards W-2 employees or 1099 contractors? 1099 guards are a huge red flag — it usually means no workers' comp, no oversight, and no real training.
- How do you supervise guards on-site? The best companies do surprise visits, GPS check-ins, and written reports.
Fourth: Demand Written Reports
If a company will not give you a written report after every shift, find another company. Reports protect you in three ways:
- Proof of service if there is a billing dispute
- Legal evidence if an incident happens
- Insurance documentation if you need to file a claim
Good companies use digital reporting tools — time-stamped, photographed, and emailed automatically.
Fifth: Get the Owner's Phone Number
If you cannot reach the owner of the company, you are signing up for problems. National chains route you through call centers. Local owners give you their cell.
When something goes wrong at 2 AM — and it will — you want a real decision-maker on the phone, not a script reader in another state.
Sixth: Read Real Reviews (Carefully)
Yelp, Google, and BBB reviews can help, but watch for:
- Fake reviews — All 5 stars, posted on the same day, from accounts with no other reviews.
- Reviews that only mention the receptionist — Means the writer never actually got service.
- Reviews from years ago — Companies change. So do their owners.
Better: ask for 3 client references you can actually call. Real companies have them. Fake ones do not.
Seventh: Compare Pricing — But Not on Price Alone
If one quote is half the price of the others, something is wrong. Either they are unlicensed, uninsured, or about to fold. We have real San Diego pricing here — anything way below those ranges should worry you.
Eighth: Look for Specialization
A company that does everything well is rare. Usually they do one or two things really well. Ask:
- How many HOA contracts do you currently hold? (If you need HOA security)
- How many construction sites do you guard? (If you need construction security)
- How many events have you staffed in the last year? (If you need event security)
A company doing 50 events a year is going to handle your wedding better than one doing 5.
Ninth: Visit Their Office
If a company has a real office, visit it. Look at the trucks. Talk to the dispatch staff. See the uniforms and equipment. A company that operates out of a P.O. box is a company you should worry about.
Tenth: Trust Your Gut
If something feels off — high pressure, vague answers, dodgy contracts — listen to that feeling. Security is something you only need to do once. The cheap option becomes the most expensive option after one incident.

How do I verify a CA BSIS PPO license?
Go to breeze.ca.gov/datamart/loginCADCA.do and enter the company name or license number. A valid license shows 'Active' status with no disciplinary actions. If you cannot find them or it shows 'Expired,' do not hire them.
What questions should I ask before hiring?
Ask for their PPO license number, COI proof, hourly rates in writing, whether guards are W-2 or 1099, what training they require, and 3 references. If they hesitate on any of these, move on.
Are national security chains better than local San Diego companies?
Not usually. Chains route everything through call centers and assign rotating guards. Local San Diego companies know the area, respond faster, and give you direct access to the owner.
How long should my security contract be?
Start with 6 months. Long enough to evaluate them. Short enough to leave if they fail. Most companies will give you a 6-month rate close to their 1-year rate.
What is the difference between BSIS PPO and BSIS guard registration?
PPO is the company license. Guard registration (guard card) is for the individual guard. A company can have a PPO and still hire unregistered guards illegally. Always ask if all on-site guards are registered.
