Direct 2.0

Dun & Bradstreet’s Online Services Security Enhancement

As part of our ongoing effort to deliver indispensable content through modern channels, Dun & Bradstreet has enhanced the security of our Online Products and Services.

To adhere with Industry best practices for security and data integrity, Direct 2.0 and Direct Onboard API’s has disabled support for Transport Layer Security (TLS) 1.0 and 1.1. The supported Cipher Suites were revised to remove weak ones and leave the following as the only supported set:

Cipher Suites supported sets:

RFC NameOpenSSL Name

Customers must ensure that their Application Program Interface (API) support TLS 1.2, the HTTPS protocol must support at least one of our supported Cipher Suites, by December 14, 2018. After that date, we disabled the TLS 1.0, TLS 1.1, HTTP protocols, and encryption.

Customer Impact

Those who are still using the older protocols after December 14, 2018 are prevented from accessing the noted products, applications, and services. Connections to or from a customer’s API or web browser that rely on the older protocols will fail. The disruption of service may include failure to connect, inability to send/receive data and/or files, and/or inability to log into their Dun & Bradstreet products and services.

What Actions You Need to Take

Customers are required to always use TLS v1.2 when connecting to Dun & Bradstreet APIs.
