In addition, if the question is about WebUI TLS version, you can easily check it yourself in the browser. This is for portal.checkpoint.com:

As you can see, TLS 1.3 is used

Hey brother,

Val is 100% right. Even chatgpt shows the same. I also attached screenshot as an example for community site.

Hey mate 👋 — assuming by S1C you mean Check Point Smart‑1 Cloud.

Short answer

• Smart‑1 Cloud / Infinity Portal WebUI (portal.checkpoint.com) negotiates TLS 1.3. [community....kpoint.com]
• For other Smart‑1 Cloud components/flows (APIs, SmartConsole connectivity, etc.), Check Point points to SK178505 (“Which TLS version do Check Point products use?”) as the authoritative matrix (it’s behind a Support Center login). [community....kpoint.com], [support.ch...kpoint.com]
