Email.Security.Cloud Planned Maintenance

At Broadcom, we are committed to maintaining the highest security standards for your organization’s email. As part of our ongoing efforts to protect against emerging vulnerabilities, we are updating the SMTP TLS protocols and ciphers that Email Security.cloud supports and are beginning to phase in support for TLSv1.3. Support for the following outdated and weak encryption protocols will be phased out:

• SSLv3 (all ciphers) and legacy ciphers including RC4, SEED, CAMELLIA, and 3DES across TLSv1.0, 1.1, and 1.2.
