TLS 1.3 Support Check

Viostream is discontinuing support for TLS 1.2 across all customer-facing services on 31 October 2026. From this date, all connections to Viostream -- including video playback, embeds, the API, and the management console -- will require TLS 1.3.

Why we're making this change​

TLS 1.3 is the current industry-standard protocol for securing data in transit. Moving to a TLS 1.3-only configuration lets us:

  • Remove outdated cipher suites and key exchange methods that are no longer considered best practice
  • Reduce our exposure to legacy protocol vulnerabilities
  • Lay the groundwork for post-quantum cryptography -- TLS 1.3 is required to support the new quantum-resistant key exchange algorithms (ML-KEM) that AWS and the broader industry are rolling out, protecting your data against future "harvest now, decrypt later" threats from quantum computing

Who this affects​

TLS 1.3 has been supported by all major browsers and platforms for several years, so most integrations will be unaffected. You may need to take action if you have:

  • Custom server-side integrations or scripts that pin an older TLS version
  • Legacy devices, SDKs, or embedded systems that only support TLS 1.2 or earlier
  • Corporate proxies or firewalls that restrict outbound TLS versions

What you need to do​

If the checker above reports that your connection doesn't support TLS 1.3, update your browser, operating system, or network configuration before 31 October 2026. Common fixes include:

  • Updating your browser or OS to a current, supported version
  • Asking your network or IT team to allow outbound TLS 1.3 through any corporate proxy or firewall
  • Updating custom integrations, scripts, or devices that pin TLS 1.2

If you run into any TLS 1.3 compatibility issues, get in touch with our support team and we'll help you sort it out ahead of the cutover.
