Security Protocol Enhancements and TLS Cipher Suite Update

In our ongoing efforts to maintain the highest security standards, we are updating the Transport Layer Security (TLS) protocols and cipher suites for all ThousandEyes services.

After September 2nd, 2024, the following changes will be in effect for all ThousandEyes services:

• Added support for TLS 1.3 protocols, enabling more secure and efficient cryptographic handshakes.

• All Cipher Block Chaining (CBC) ciphers from the TLS 1.2 suite will be deprecated due to their susceptibility to specific vulnerabilities.

Updated supported Cipher Suites:

• TLS 1.2: ECDHE-RSA-AES128-GCM-SHA256, ECDHE-RSA-AES256-GCM-SHA384, and ECDHE-RSA-CHACHA20-POLY1305.

• TLS 1.3: TLS_AES_128_GCM_SHA256, TLS_AES_256_GCM_SHA384, and TLS_CHACHA20_POLY1305_SHA256.

This update ensures compliance with the latest security standards and best practices, reducing the risk of exposure to known vulnerabilities associated with CBC ciphers. Clients and integrations must support the aforementioned cipher suites to maintain compatibility with our application.

We encourage all users to verify their systems' compatibility and make any necessary adjustments to continue enjoying secure communications with our application.
