Northern Trail Outfitters (NTO) is concerned about unauthorized API access to their Marketing Cloud account.

To enhance security against unauthorized API access:

Enable IP Allowlisting: Restrict API access to pre-approved IP addresses. This security feature ensures that only requests coming from known and trusted IP addresses are allowed to access Marketing Cloud, significantly reducing the potential for malicious attacks.

Configuration: Configure the IP Allowlist settings in the Setup area of Marketing Cloud, specifying which IP addresses are permitted to make API calls.
