Marketo is strengthening our encryption protocols and following security best practices.
RC4 cypher used in TLS/SSL transactions is no longer considered s strong security protocol and will be gradually disabled on Marketo networking devices, starting July 20, 2015.
No interruption of Marketo SaaS services is expected as a result of this change.
Customers with legacy systems dependent on RC4 are advised to update any API components used to connect to Marketo SaaS APIs in order to support other secure protocols and cyphers such as AES, 3DES, or ECDHE .
If you encounter any issues please contact Marketo Customer Support.
