The security company you hire is responsible for protecting your people and your property, and for representing your business to everyone who walks through your door. Hire the wrong one and you inherit their problems: untrained guards, no accountability when something goes wrong, and liability that lands on you. The hard part is that every security company says the same things in a sales pitch. The difference shows up in the details.
This guide gives you the specific red flags that should end a conversation, and the green flags that tell you a company is worth your contract. Use it as a checklist before you sign anything.
1. Red Flag: They Will Not Show You a PPO License Number
In California, every security company must hold a Private Patrol Operator (PPO) license from the Bureau of Security and Investigative Services. A legitimate operator gives you that number on request and often publishes it on its website. If a company dodges the question, gives you a vague answer, or sends a screenshot instead of a number you can verify yourself at the state license search, walk away. You cannot confirm they are operating legally, and that is the most basic requirement of all.
The green-flag version: the company hands over its PPO number freely, and when you search it at search.dca.ca.gov, the status is active with no disciplinary actions.
2. Red Flag: Vague Answers on Guard Training and Screening
“Our guards are highly trained” means nothing without specifics. Ask exactly what training their guards complete and how they screen new hires. California requires guards to pass a Department of Justice and FBI background check, complete Power to Arrest training before being issued a registration, finish 32 hours of skills training within six months, and complete 8 hours of continuing training each year. A company that cannot speak to these requirements clearly either does not follow them or does not track them.
The green flag is a direct, detailed answer: guards carry valid California guard cards, pass background checks and drug testing, and receive documented onsite field training for the specific post they will work. A company that trains guards for your site, not just for a generic shift, is a company that takes the assignment seriously.
3. Red Flag: No Proof of Insurance, or a Thin Policy
A security incident can produce a claim far larger than a small insurance policy can absorb, and if your security company is underinsured, the exposure can flow back to you. A company that hesitates to provide a current certificate of insurance, or carries only minimal coverage, is a financial risk to your business.
The green flag is a company that is licensed, insured, and bonded, and proves it on request. Look for meaningful liability coverage. OnGuard, for example, carries a policy that pays up to $1.5 million per occurrence, covering property damage and bodily injury. Ask for the certificate, confirm the policy is active, and confirm the coverage amount before guards start.
4. Red Flag: No Supervision or Accountability System
Hiring guards is easy. Making sure they actually show up, stay alert, and do the job is the hard part, and it is where weak companies fall apart. If a company cannot explain how it supervises guards on duty, how it confirms a guard arrived and stayed on post, or how you reach someone if there is a problem at 2 a.m., you are buying a name badge, not security.
The green flag is a clear accountability system: supervisors who check posts, technology that tracks guard location and clock-ins in real time, and a 24/7 dispatch line you can actually reach. OnGuard runs live supervisor tracking through its OnGuardLive app and monitors officers around the clock, sending a supervisor out if a guard does not clock in on time. That is the kind of system that turns a promise into a service you can rely on.
5. Red Flag: High-Pressure Sales and Long Lock-In Contracts
Be cautious of any company that pressures you to sign quickly, will not put its commitments in writing, or locks you into a long contract before you have seen the service. A long lock-in protects the company, not you, and the urgency is usually a tactic.
The green flag is flexibility and transparency: a written proposal with clearly defined post orders, pricing you can understand, and terms that do not trap you. OnGuard works without long-term contracts, which means the company has to keep earning the relationship rather than relying on a signature to keep you. A provider confident in its service does not need to lock you in.
6. Green Flag: A Real Process, Not Just a Quote
The best sign you have found the right company is how it approaches the work before you sign. A serious provider does not just quote a guard count. It assesses your site, identifies your actual vulnerabilities, and proposes a plan built around them.
Look for a defined process: a free consultation, a threat and vulnerability assessment, a customized written proposal, assigned post orders, and a named supervisor for your account. This is exactly how OnGuard structures every engagement, drawing on more than eight years protecting California businesses across industries from retail centers to construction sites. When a company invests in understanding your property before asking for a contract, that is the clearest green flag of all. You can review the range of security guard services a full-service provider should offer as a benchmark.
Frequently Asked Questions
What should I look for when hiring a security guard company in California?
Confirm a valid PPO license at the state search, current insurance and bonding, specific answers on guard training and screening, a real supervision and accountability system, and flexible written terms. A company that assesses your site before quoting is a strong sign.
What are red flags when choosing a security company?
The biggest red flags are refusing to share a verifiable PPO number, vague answers about training and background checks, no proof of insurance, no system to supervise guards on duty, and high-pressure sales pushing a long lock-in contract.
Should a security company provide proof of insurance?
Yes. Always ask for a current certificate of insurance, confirm the policy is active, and check the coverage amount before guards start. An underinsured company can leave you exposed to claims arising from incidents on your property.
Are long-term contracts normal for security services?
They are common but not required, and a long lock-in mainly protects the provider. Companies confident in their service, such as those offering month-to-month or no-contract terms, give you the flexibility to leave if the service does not deliver.
How do I verify a security company is licensed?
Use the California Department of Consumer Affairs license search at search.dca.ca.gov, select Private Patrol Operator, and enter the company name or PPO number. Confirm the license is active with no disciplinary actions before signing.
