What is SSL Labs?
SSL Labs is Qualys' free online SSL/TLS security testing service that performs deep analysis of SSL web server configurations on the public Internet to identify security vulnerabilities and grade SSL implementations. Agent Analytics can track when it visits your website.
Category
Expected Behavior
SSL Labs's pattern depends on who pointed it at you. Continuous monitoring services check daily or even hourly, while a one time assessment sweeps once and disappears. Expect requests aimed at login pages, admin paths, APIs, and configuration files, because exposed ones are what scanners exist to find.

Disallow: /Frequently Asked Questions
Should I Block SSL Labs?
Not unless you already run your own scanning and want cleaner logs. SSL Labs checks websites for exposed vulnerabilities, and some scanning services report what they find to site owners for free. Almost none of the top websites we track have robots.txt rules for SSL Labs right now.
Does SSL Labs Respect Robots.txt?
Yes. SSL Labs is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms SSL Labs actually honors it.
Does SSL Labs Access Private Content?
It probes for private content deliberately. Login pages, admin panels, and API endpoints are exactly what SSL Labs tests, because exposed ones are what it exists to find. Probing is not the same as getting in, but expect requests to sensitive paths in your logs.
Why Is SSL Labs Visiting My Website?
SSL Labs is scanning your site for vulnerabilities, either as part of a sweep across the whole internet or because someone requested an assessment of your domain. Recurring visits usually mean a monitoring service has you on its list.
How Can I Tell if SSL Labs Is Visiting My Website?
Agent Analytics tracks SSL Labs visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "SSL Labs". Look for probes of login, admin, and API paths. Keep in mind that SSL Labs doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
