What we Do

Professional Office Security Service in San Francisco

Keeping your office facilities safe and running at peak efficiency is a critical concern. An office security service presence helps you prevent unauthorized access to your premises and assures that both visitors and personnel enjoy the benefits of a secure environment.

Lobby Security

First impressions count. On any given day, the people who walk through your doors represent all walks of life, and it is essential that they are all afforded the courtesy they deserve. Your lobby security is often the first point of contact, and it is an interaction that sets the tone for the individual’s time on your premises.

Our Reviews

Office Security Case Study:

A San Francisco Marketing Firm’s Breach of Premises

A third-party marketing firm, located in the city, experienced a break-in that compromised their server room, potentially exposing their most important client’s data to malicious intent. They had a critical need to prevent any further incidents, and it was essential for them to find an immediate solution, or they would risk losing the contract altogether.

The company contacted us, and we were able to schedule after-hours security coverage right away. Soon, they had complete peace of mind, knowing that their facilities would never sit empty.

Our team worked with building management and their alarm company to strengthen their access points, adding door alarms and redirecting alarm calls to go directly to our security officer. We posted an officer in the lobby to validate all incoming personnel, both with and without access badges. As a result, their employees were able to come and go securely, and the risk of gaining entry by claiming a lost access badge was minimized.

These changes helped the company assure their client that there was little to no possibility of a further breach, further solidifying their relationship. By minimizing and managing the risk, the company became stronger as they were able to focus more on growing their company and less on worrying about their assets.
