What Our Clients Say About Us

Industry Custom Security Approach
Different industries have different security needs by necessity. STT has decades of experience serving nearly all industries including but not limited to: shopping centers, retail, healthcare, commercial offices, educational facilities, schools, entertainment venues and theaters, manufacturing facilities, hospitality and hotels, and many others. We understand the uniqueness of these industries needs and to build a successful security program within them.
A security guard or team who doesn’t understand the industry they were assigned to protect cannot offer the business the same value. That’s why we’ve taken great care to speak to industry professionals, engage in professional organizations for the industries we serve, and do our best to understand an industry and build industry specific programs to serve clients before we ever place a guard on the premises. We train our guards on the different industries they’ll be protecting and the protocol associated with the various needs and nuances. Our guards are well versed in the needs of the industries they’ve been assigned to, and they’re always ready to learn more to better protect your interests.
We work with the industries we serve, and not as an arm that doesn’t know what the body is doing. We’re a valuable addition to your team, providing security guard services in the San Francisco Bay area to all kinds of businesses. No matter what you need or what kind of business you’re in, STT Security is here to help keep you safe and secure. We’re your partner, and we care about keeping you safe and providing the best value for your security investment.
Shopping around? Don’t forget to ask these questions…
- PHave vendors visit and inspect job site to make professional recommendations for solutions. If a vendor can’t make time to come meet with you, it’s likely that that poor level of support will continue down the road.
- PAs the client, specify (or work with the vendor) to set wages that match your business needs, culture, and security responsibilities for the positions needed.
- PAsk for a pricing structure that allows for wage transparency and detailed billing with employee wages included; this way, you can ensure your vendor is supplying the agreed upon wages.
- PDoes this vendor have sufficient local management staff and infrastructure to support my specific needs?
- PDoes the vendor have proven experience in my specific industry?
- PRequire at least 1 past and 1 current client reference, and take the time to speak with them about the vendor, their staff, management, and overall experience with the company.
- PIs the vendor licensed to provide security services in the state of California? Ask for a copy of their up-to-date/current license.
- PIs the vendor currently involved in any lawsuits?
- PIs the vendor in a stable financial position?
- PHow much liability insurance protection does the vendor provide, and will they name your business as a co-insured?
