A suction-security system includes an adhesion membrane coupled to a swing arm. Rotation of the swing arm lifts a center portion of the adhesion membrane, creating suction and adhesion of the suction-security system to an anchor surface. The swing arm may have a low profile enabling use of the suction security system in an enclosure with minimal loss of available interior space. The system may include a shield protecting the adhesion membrane, and a bushing in the shield permits rotation of a portion of the shield without disturbing adhesion of the adhesion membrane to the anchor surface. The suction-security system may be used in consumer items such as purses, backpacks, briefcases, and suitcases.
