Certified Lodging Security Officer (CLSO)

Certified Lodging Security Officer (CLSO)

Security officers play a crucial role in making your property safe and protecting guests, employees and the property itself. They do this by effectively handling routine security activities and emergencies with sound judgment and quick response. They are skilled at recognizing threats and securing the property, all while providing good guest service. The Certified Lodging Security Officer (CLSO) designation recognizes how hard these staff members work hard to keep everyone safe. Security officers may pursue this certification on their own or through group training at the property or organizational level.

Candidates for the CLSO must show proof of current, full-time employment as a hospitality security officer for 90 days.

Completion of the Lodging Security Officer Program, either through self-study or in a group training program, is highly recommended for those preparing to take the CLSO exam.
