Whitelisting Corppass IP Addresses for Outgoing Traffic

Why can't I whitelist Corppass IP addresses for outgoing traffic?

For enterprise networks or networks with restricted traffic, it's common for system administrators to configure a whitelist of outgoing traffic. However, Corppass advises against whitelisting IP addresses and recommends whitelisting by domain instead. Here's why:

• Corppass operates on AWS: Corppass uses CloudFront, which relies on a large and dynamic pool of IP addresses to ensure high availability of services. This list of IP addresses can change periodically.

• IP addresses may change: If you whitelist Corppass endpoints by IP address, there's no guarantee that these addresses will remain static. Changes in IP addresses can cause disruptions, preventing your e-service from accessing Corppass.

Therefore, whitelisting by domain is always the preferred and more reliable method.

Can I still use IP address whitelisting for Corppass?

If you must use IP address whitelisting, refer to the following AWS CloudFront resources:

• AWS CloudFront Edge Server Locations

• List of CloudFront IP Addresses

However, please note that using these resources may still result in disruptions due to changes in IP addresses over time.
