Update
[5:23 PM EST 10/20/2026] As we continue our response to the Bullhorn Platform security incident, please be vigilant against potential social engineering attacks. Threat actors may pose as Bullhorn personnel via email, text, or phone calls, using the incident as a pretext to request credentials or sensitive information. Please note that Bullhorn will never ask you to share your password, Multi-Factor Authentication (MFA) codes, or verification tokens via email, telephone, text, or any other channel.
All regions are now online and we are continuing to monitor.
Fixes have been implemented for the following:
- SSO access from the ATS to external applications and Bullhorn applications has been restored for the US. Other regions are being worked on.
- SSO customers who were experiencing challenges previously are asked to test again and log a ticket via support if issues persist.
- Bullhorn owned customizations across all regions are also in the process of being brought online.
- Ability for ATS Admins to edit users and manually set passwords has been restored in the application.
For a comprehensive list, please see our Known and Resolved Issues and Integrated App Status.
