Limiting power of untrusted certificate authorities is disclosed. An unstructured list of certificate authorities associated with an application may be augmented with a limiting database that includes a per target certificate authority list. For targets identified in the limiting database, the certificate of an entity may be trusted only when the certificate authority is in the target's list, even if the certificate authority is present in the unstructured list of certificate authorities.
