A system and method to ensure trustworthiness of a remote service provided by a service provider. The method includes monitoring runtime dependencies invoked during execution of a service transaction associated with the remote service, the service transaction being requested by a service requester. The method further includes determining whether a deviation exists between the runtime dependencies and a trusted list of dependencies associated with the remote service. The method also includes blocking execution of the service transaction based on determining that the deviation between the runtime dependencies and the trusted list of dependencies exists.
