If your security policy is designed to explicitly allow IP addresses on your network, identify the region in which your account is deployed and add the associated IP ranges to your firewall.
- Ingress addresses (previously referred to as Core addresses) should be applied to all use cases.
- Egress addresses (previously referred to as Webhook and Callback addresses) are only required if using the webhook service or callback URLs. (Both in Production and Sandbox environment.) The webhook and callback services use the same IP addresses.
- Sandbox address only pertains to the entitled Sandbox environment.

Note:
If you have IP restrictions configured under the Security Settings tab in your Acrobat Sign account, we will allow logins only from those IPs. For more information, refer to this documentation.
IP ranges for outbound mail relays
If your organization explicitly lists IP addresses to control connection to your inbound mail servers, add the following IP addresses to your allowed list of IP ranges:
- 40.65.170.152/30
- 40.67.157.141/32
- 40.67.154.24/32

Transport Layer Security (TLS) is the most widely deployed security protocol used today for Web browsers and other applications that require data to be securely exchanged over a network. Connections to Acrobat Sign require the use of TLS 1.2 and support for at least one of the cipher suites below. These requirements apply both to inbound traffic to Acrobat Sign servers (browsers, API) and outbound traffic from Acrobat Sign servers to customer servers (API callbacks used for retrieving agreement source documents, returning status, and webhooks).
For browsers: as long as you adhere to the OS/Browser requirements, you should have no browser-related issues. All these OS/browsers are fully compliant with our TLS requirements.
For applications using the Acrobat Sign API, these frameworks support TLS 1.2:
- Java: use Java 8 or later
- .NET: use .NET 4.6 or later
- OpenSSL: use OpenSSL 1.0.1 or later
For servers used to receive callbacks or webhook requests from Acrobat Sign:
- Support TLS 1.2 and at least one of the cipher suites listed below
- Have a valid TLS certificate, and include all intermediate certificates.
Customers who wish to test that their server is compliant can use a variety of free or commercial tools, including the Qualys SSLLabs Server Test, to ensure that their server accepts TLSv1.2, supports at least one of the cipher suites below, and has a valid certificate.
TLS Cipher Suites Supported:
| IANA Name | OpenSSL Name |
| TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 | ECDHE-ECDSA-AES128-GCM-SHA256 |
| TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 | ECDHE-RSA-AES128-GCM-SHA256 |
| TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 | ECDHE-ECDSA-AES256-GCM-SHA384 |
| TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 | ECDHE-RSA-AES256-GCM-SHA384 |
| TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 | ECDHE-ECDSA-AES128-SHA256 |
| TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 | ECDHE-RSA-AES128-SHA256 |
| TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 | ECDHE-ECDSA-AES256-SHA384 |
| TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 | ECDHE-RSA-AES256-SHA384 |
