Question
What are the IP addresses or domains for the Contrast SaaS instances?
Answer
Inbound Traffic to the Contrast UI
For traffic that is inbound to the Contrast UI (for example all Contrast agent traffic and end-user's browser traffic):
Static IP address list (Current Configuration)
As of mid-November 2021, the following static IPs are shared across all Contrast SaaS instances and environments:
| 151.101.2.246 | 151.101.2.232 |
| 151.101.66.246 | 151.101.66.232 |
| 151.101.130.246 | 151.101.130.232 |
| 151.101.194.246 | 151.101.194.232 |
In addition, the server certificate will be signed by GlobalSign.
AWS Regions (Deprecated as of November 2021)
An AWS Elastic Load Balancer is used, meaning the IP range is dynamic. As such, the Contrast Cloud Engineering team recommend binding to the DNS entry (eg. app.contrastsecurity.com), if that is an option for your firewall. However, if that isn't an option, AWS allows you to filter to the correct range, as described here: AWS IP address ranges
| Contrast SaaS UI FQDN | AWS Region | Services |
| app.contrastsecurity.com | us-east-1 | EC2, CLOUDFRONT |
| app.contrastsecurity.jp | ap-northeast-1 | EC2, CLOUDFRONT |
| cs001.contrastsecurity.com | us-west-2 | EC2, CLOUDFRONT |
| eval.contrastsecurity.com | us-east-1 | EC2, CLOUDFRONT |
The certification path is as shown below:
