Claim:
1. A method, for accessing a protected filesystem on a host computer, comprising: receiving a request from an accessing process associated with a requestor to access the protected filesystem; verifying access rights associated with the requestor by (i) validating authorization of the associated accessing process based on a process whitelist and (ii) determining whether a current time associated with the access request of the accessing process is valid based on a timestamp history of the host computer access requests to the protected filesystem; determining whether the host computer is online based on a response from an online server; if the host computer is not online, determining whether a license to access the protected filesystem is valid based on an expiration within the license; in response to a valid determination of the license when the host computer is not online, receiving a filesystem key; and decrypting the protected filesystem based on the filesystem key.
