Hello Valued Partner
Thank you for visiting the Catalyst Vendor Self-Enrollment
Portal. We will no longer be accepting new requests for access as
Sanofi’s vendor portal moved. Please email your request for access to firstname.lastname@example.org
The Catalyst URL has changed to https://sanofi.catalyst.cognizantproducts.com. Please update accordingly, as users will be temporarily redirected from the old URL.
