IT Admins | How do I add Cirrus Insight to trusted/allowed lists?


IT departments should allow Cirrus Insight communications and connections to ensure users have full access and functionality.  The Cirrus Insight application, emails, IP addresses and API calls should be added to trusted/allowed lists. 

Many organizations do not need to perform this work, but if your environment requires any or all of the measures below, your IT department can implement these recommendations.

Email Delivery

Cirrus Insight uses email verification for account activation and password reset.  Additionally, there are system generated communications for training and updates.  To ensure Cirrus Insight emails are always delivered and never show up in your Junk Mail folder, your IT department can allow "" and "" on the mail server.                     

Salesforce App Authentication

Salesforce has several mechanisms to prevent or allow connected apps to authenticate. Consult with your Salesforce Administrator if necessary.

Salesforce Login IP Ranges

Salesforce allows administrators to restrict the IP addresses that are allowed to log into their Salesforce environment.  If your org restricts Login IP Ranges, you will need to add Cirrus Insight’s list of IPs to your configuration.




 Implementing Login IP Ranges

  • Contact Manager (Group, and Professional editions) - Login IP Ranges are found under Security Controls > Session Settings (This will apply globally to all users).
  • Enterprise (Unlimited and Developer editions) - Login IP Ranges are managed on a per Profile basis, and will apply only to user’s with that Profile. Profiles can be managed from the Manage Users > Profiles section.
