Dun & Bradstreet's Online Services Security Enhancement Release Scheduled for May 31, 2018

14 maalis 2018

As part of our ongoing effort to deliver indispensable content across modern channels, Dun & Bradstreet will be enhancing the security of our Online Services on Thursday, May 31, 2018.

What is the impact of the change?

Dun & Bradstreet is committed to ensuring our customers’ security when using our products and services. Our aim is to mitigate exposure to vulnerabilities that target the secure connection established between a customer’s Application Program Interface (API) or web browser and Dun & Bradstreet’s websites and applications.

To stay ahead of these potential vulnerabilities, we will disable support for Transport Layer Security (TLS) 1.0 and 1.1. All customers using Toolkit, Toolkit API, Direct 1.x, Direct 2.0, Direct+, Direct OnBoard,, D&B Credit, and DBIA will be impacted by this change.

We will also restrict access to Toolkit through the HTTPS protocol and will only support 128-bit or higher encryption. HTTP connections and encryption algorithms that are lower will no longer be supported. This affects Toolkit and Toolkit API’s.

In addition, our internal Sitescope System will also be affected. It will be replaced with a system that supports TLS 1.2 or higher. Further details will be communicated later.

Those who are still using TLS 1.0, TLS 1.1, HTTP protocols, and encryption lower than 128-bit after May 31st, 2018 will be 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 and/or encryption algorithms 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 D&B products and services.

What action do you need to take?

The action required will depend on which browsers and channels are used to access D&B’s products and services.

Customers using web browsers or APIs to access our services must ensure they support TLS 1.2 or later, on or before May 31st, 2018. After that date, we will begin disabling the TLS 1.0 and 1.1 encryption protocol. The latest version of any major supported browsers uses TLS 1.2 or later and has additional built-in safeguards to protect against known attacks. Note that support for TLS 1.2 must be turned-on and/or selected. Toolkit and Toolkit API customers must use HTTPS and 128-bit encryption (or higher) when connecting to Dun & Bradstreet.

You must contact your company’s Technical Support Team for more information and assistance.
