Free public test of a website's TLS configuration, run by Qualys.

Verdict

Paste a hostname into SSL Labs and it grades the TLS setup. The page calls this a free online service. Qualys also advertises a free trial of its paid cloud platform on the same page. That trial is not the test. The test is the thing that is free.

Who it is for
Anyone who wants a second opinion on a public site's certificate and TLS settings.
Free tier
The SSL Server Test is free. The page says the information you submit is used only to provide the service. Checked 14 Oct 2026.
Pricing note
The test has no price. Qualys's separate cloud platform has its own free trial, which we are not treating as the price of this test.

Ownership
Independent of this directory. The page says the test is powered by Qualys SSL Labs.

What holds up

  • Free, and the page says free.
  • You do not create an account to run a test.

What to watch

  • It tests a public site. It does not watch it next week.
  • The Qualys trial ad sits next to the free test and is easy to mix up.
