Customers should engage their network teams to consider network configurations and firewall settings to accomodate the following modern updates and advancements:

1. Flexibility, scalability, and reliability is achieved using HTTP internet based communications. Equifax services are hosted in a highly scalable cloud environment with a vast number of possible IP addresses. If destination/egress filtering is required by your organization, Equifax strongly recommends handling this via URL/FQDN.

2. Best-in-class security is supported by TLS 1.2 with strong cipher encryption.

3. Source IP Address whitelisting on our services is available if your organization requires this.

NOTE: IPv4 and IPv6 CIDR is supported.
