Security Industry Specialists, Inc. (SIS) provides innovative security solutions and services for people, their assets and facilities, anywhere, any time, in a comprehensive manner tailored to meet the individualized needs of each client.

Our clients include Fortune 500 companies, designer brands, international events, celebrities, and high-profile executives. Founded in California, in 1999 by John Spesak, a former law enforcement officer, our client partnerships demonstrate a boutique approach; a welcome change in an industry not typically recognized for creative solutions. Mr. Spesak saw an opportunity to create a security company that would introduce excellence, innovation, and hyper-responsiveness to an industry replete with mediocrity.

As a privately held company, the executive team set out with the determined focus of partnering and growing with world-renowned brands, starting with Apple in 1999. SIS focused on providing the highest quality security services to Fortune 100 companies, believing that word of mouth would drive measured growth with select clients (instead of growth through marketing or aggressive client acquisition). Indeed, as SIS’s reputation spread across Silicon Valley, many famous brands chose to partner with SIS.
