The protection of data on a lost or stolen laptop is primarily achieved through encryption. Encryption involves converting the data into a format that cannot be easily read or accessed without the appropriate decryption key. By implementing encryption on a laptop, even if it is lost or stolen, the data remains secure and inaccessible to unauthorized users. This is particularly important for sensitive information, ensuring that it cannot be extracted or misused, even if the device itself falls into the wrong hands.

While other options like Endpoint Protection could offer some level of security in the form of malware protection and threat detection, they don't specifically address data protection in the event of physical loss or theft. Firewall and Web Filtering help to protect against external threats and control web traffic, respectively, but they do not provide the necessary safeguards for the data on a device itself. Hence, encryption stands out as the most effective solution for securing data in scenarios involving lost or stolen laptops.
