Savance-hosted cloud services operate behind Azure Front Door. Azure Front Door is a managed, globally distributed service for scaling and securing your web traffic. It uses dynamic IPv4 and IPv6 addresses to route traffic to our cloud servers, making it impossible to limit communication to a specific set of IP addresses. While limiting access to our cloud services by IP addresses is impossible, you can still ensure trusted and secure communication by whitelisting the dynamically allocated IP addresses for cloud.savanceworkplace.com. However, there are other ways to ensure trusted and secure DNS resolution. By doing so, you can ensure that only trusted traffic reaches your servers while protecting them from potential threats.
