They should also examine the endpoints on their network for any instances of WhatsApp being installed or used. This information will help security professionals to identify any potential risks associated with the use of WhatsApp on their network and take appropriate action to minimize those risks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
