The internet's SSL/TLS security score

An average score masks a divided web

Fair83 / 100

The average SSL Monitor score for the top million sites is 83 (Fair).

This average grade hides a split - many sites with excellent security and many with rather poor security. Most responding websites now negotiate modern TLS; 34.9% still accept TLS 1.0 (often a deliberate choice to reach older devices). On other measures, though, many websites lag well behind best practices. For example, only 61.3% offer post-quantum key agreement.

When you visit these websites

What will a visitor to these websites see? No HTTPS at all, a certificate that breaks, serious issues, secure, or fully secure (A+ with nothing to fix)?

1.8%of the 1,000,000 websites have no HTTPS at all.
Assessed websites are every website in the report whose scan completed; the deep-scan coverage is stated in the methodology.Denominator: websites · n = 1,000,000

Methodology

Everything below is pinned per run — the scanner image, testssl build, scoring algorithm, aggregator, ASN database, dotgov list, industry list and compliance rules — so any month can be recomputed from its raw data.

Not affected by the filter above.
  • PopulationThe top 1,000,000 websites from the Tranco list published for October 2026. The list is seeded beyond one million ranks and filled in rank order: 1,121,989 domains were crawled to reach 1,000,000 websites, and 121,989 were excluded from the report: domains that don't resolve, hosts that block our scanner, and hosts with no HTTP/HTTPS that are infrastructure.
  • Outcome mappingEvery website is mapped to an outcome: no HTTPS response → Website with no HTTPS; untrusted or missing certificate → Certificate breaks; a HIGH/CRITICAL vulnerability prerequisite or a grade of B or below → Serious issues; A−/A → Secure; A+ → Fully secure.
  • ScoringWebsites are rated using GeoTrust SSL Monitor's SSL/TLS security score, which incorporates 35+ factors into an overall score. Scoring factors include certificate trust; expiry; HTTPS configuration; and protocol, cipher and vulnerability checks.
  • Classified slicesIndustry/country/region/gov cohorts are created using several data sources, including the CISA .gov registry, domain TLD, the site's own contact details, and categorization by a language model.
  • Generated2026-10-30T01:20:17.469Z

How we scan / opt out

The scanner runs the same way other established internet-measurement projects do: identified, published and polite.

  • User-AgentEvery HTTP request identifies itself as Mozilla/5.0 (compatible; StateOfSSL-Research/1.0; +https://www.geotrust.com/research/state-of-ssl), with ordinary Accept and Accept-Language headers.
  • Source addressesA fixed pool of Elastic IPs in a dedicated AWS account; each carries a reverse-DNS name matching stateofssl-scanner-NN.sslviking.com, so a connection from the scanner can be attributed with a single PTR lookup.
  • What one scan isOne deep TLS handshake set per host per month (protocols, ciphers, certificate chain, key exchange, vulnerability prerequisites) plus two plain GETs — port 80 for the redirect chain and port 443 for the response headers. No login, no forms, no crawling beyond the landing page, no retries against hosts that challenge. A domain whose HTTPS does not answer is also tried at www.<domain>, and one that answers nothing at all is tried once more later in the same run before it is set aside.
  • Opt outContact GeoTrust support (geotrust.com/support) with the domain and it joins the opt-out list, which the seeder applies before any shard is built — an opted-out domain is not contacted at all in later runs. Requests are handled within one business day.
