The out-bound email IP ranges for Adobe Acrobat Sign can be found here >

Accounts with restrictive network security will need to explicitly permit Adobe required domain names. The following domains must be allowed to ensure basic functionality:

adobesign.com
adobesigncdn.com
documentcloud.adobe.com (This is required for the Manage and Home pages)
echosign.com
echocdn.com

Note:

Accounts with very restrictive network security will need to explicitly permit the large lists below

Comprehensive domain name lists (Updated February 27th, 2024)

IP Ranges to explicitly allow

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:

Acrobat Sign will deploy the Akamai WAF (Web Application Firewall) integration to the Acrobat Sign Production starting January 13, 2025

This enhancement routes traffic to Acrobat Sign application servers via the Akamai infrastructure, improving the service security and robustness. As a result, web service and API frontend servers will no longer use specific fixed IP addresses.

If your network security rules restrict outbound connections based on IP allow lists, this integration with Akamai WAF will make the Acrobat Sign service inaccessible. Therefore, any IP-based restrictions for outbound connections to the Acrobat Sign services must be removed.

Note that this does not affect the IP addresses used by Acrobat Sign servers to connect to your servers for webhooks/callbacks.

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

SSL/TLS Requirements

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
