Required Security Change for All ACE Portal Accounts

Customs and Border Protection recently sent CSMS# 17-000217 advising of changes in the ACE portal and  then followed up with an e-mail requesting this information be disseminated to all trade associates.

Federal Regulations require that sensitive data be protected when being disseminated over the internet. Transport Layer Security (TLS) is the government approved security mechanism to protect sensitive data during internet transmission. Currently, ACE supports versions 1.0, 1.1, and 1.2 of the TLS protocol.

On May 1, 2017, U.S. Customs and Border Protection (CBP) will discontinue supporting versions 1.0 and 1.1 of TLS. To comply with government regulations, all ACE Secure Data Portal users are being notified that CBP will be phasing out versions 1.0 and 1.1 of TLS and will only support version 1.2

Please note:  The ACE Portal will not be accessible to users who operate computers that run operating systems older than Windows 7.
