An equipment lock is a physical security device that attaches a laptop to a fixed object, such as a desk or a table, with a cable and a lock. This can prevent the laptop from being stolen by unauthorized persons.
Encryption, LoJack, multifactor authentication and bollards are other security measures, but they do not physically prevent theft. Verified References: https://www.comptia.org/blog/physical-security https://www.
