We had a large family reunion at a community park and the city required us to have private security offices on-site during the party. We contacted Delta and they provides us with two security guards for 8 hours for only $300! Their rate was way lower than anyone else we contacted and they were very polite and professional.

Thank you for the great service. Your employee showed up a little early and did a great job. I will recommend your company to anyone who needs security guard service. I informed the community center of you and they are going to add you to their list of vendors. Thanks again, Hugh

We chose to have security at home during my Dad's funeral since we had heard of people using the obituaries to break into houses. All About Security patroled both the front and back of the house the entire time we were gone for a reasonable price.

Brothers In Law Private security is, I believe, the BEST local security company. The owner and employees are personable, trustworthy and hardworking. This is not a company that cuts corners; in my experience many security companies do as little as possible to finish the job, but with BIL they will go above and beyond. BIL security is a family owned business that was started from the ground up by the current owner, and it is clear he takes great pride in this company. I highly recommend Brothers In Law private security for a thorough, honest and exceptional service.

Working with Daniel Acosta was truly a pleasure. We used them to help facilitate guests for a private wedding celebration of ~150 guests in SF. What can I say - we were impressed. Their level of professionalism is far superior to any other security service we've received. They not only called us a few days before to confirm the logistics, but also the day of to ensure everything would be planned successfully. The guard (Mr. Lee) was extremely courteous, responsive, and professional. Thanks Daniel Acosta Corporation! Highly recommend!
