Systems and methods for receiving a request to analyze trust of a client system and perform actions based on a client trust profile. A trust rating server device receives a request from a client computing device to analyze the trust on the device. The request identifies at least one credential or certificate installed on the device for example. The credential or certificate is obtained and analyzed to identify key information that relates to trust, such as level of encryption, country or entity of origin, duration of credential, certifying authority, etc. A rating is established using the key information and compared to a profile or other metric. One or more credentials or certifications may be blocked, disabled, enabled or removed based on a user's profile. Trust credentials are continuously monitored on the device for changes, and new credentials are blocked that do not meet thresholds established in the user's profile.
