School Gate Guardian has been proudly servering Public and Private schools in the United States since 2008. Our goal at School Gate Guardian is simple: Help keep schools and students safe from sex offenders, unwanted visitors and other threats through the use of an easy to use and secure visitor management system. The majority of schools in our nation are still relying on outdated methods of signing in and tracking visitors. Too many times, sex offenders or other unwanted visitors are allowed easy access to schools and students. Secure entry ways and video surveillance are all great pieces of a security puzzle, but without proper visitor screening software you may be allowing potential threats into your schools on a daily basis. The School Gate Guardian Visitor Management System is the missing piece to your security puzzle. School Gate Guardian — the complete visitor management and security system for our nation's public and private schools.
