Security Industry Specialists

ABOUT SIS

Security Industry Specialists, Inc. provides unique security solutions to some of the most successful names in business. Our clients include Fortune 500 companies, designer brands, international events, celebrities, and high-profile executives.

Founded 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.  Qualities that SIS brings include transparency, integrity, sophisticated capabilities, and commitment to continuous process improvement.  In turn, these qualities have allowed us to position ourselves as the source for truly innovative services and ideas. We work with each client individually to satisfy their security needs. With everything from physical security to GSOC operations to executive protection, we are a full-service corporation committed to excellence.

Our corporate culture is the result of our commitment to our clients and our personnel, rather than just an abstract idea or concept. Those who have experienced SIS will attest to the fact that there is something different about the way our employees conduct themselves and feel about their responsibilities. Ultimately, it is this commitment and drive that separate SIS from the competition.

With corporate offices in Culver City, Seattle, San Jose, Miami, New York City, Mexico City, and Brazil; SIS has a global presence. More than a security company, we have a robust training program, a brand and content creation team, a software development department, and more. We are constantly building new and exciting solutions, and growing our company. With more than 6,000 employees stretched throughout the globe, we are committed to each individual’s success.

 

You may not recognize our name, but that’s part of the appeal. Our fantastic work is professional, private, and personal — for every client, every day
