Why Is Qualys Visiting My Website?
Someone, most likely on your own team, configured Qualys to check your site. Uptime monitors, performance testers, and audit tools visit only the sites or endpoints they are told to watch.
Should I Block Qualys?
Only if no one on your team relies on it. Qualys may support uptime monitoring, performance tests, or audits. Blocking it without checking first can silently disrupt those workflows. For context, 7% of the top websites we track currently have robots.txt rules for Qualys.

Frequently Asked Questions
What Traffic Patterns Should I Expect From Qualys?
Qualys's traffic often follows fixed intervals like a cron job. Activity may consist of short recurring checks or occasional intensive bursts, but it usually remains limited to a specific set of pages or endpoints.
Does Qualys Follow Robots.txt Rules?
No. Qualys is not expected to follow robots.txt rules, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Is Qualys Used for AI Model Training?
Not ordinarily. Qualys is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking Qualys Affect AI Search or Citations?
Not directly. Qualys's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does Qualys Access Private Content?
Only when configured with access. A team may grant Qualys credentials to monitor staging sites or private health endpoints. Without those credentials, it sees only public pages.
How Can I Verify a Request From Qualys?
Agent Analytics tracks Qualys visits in real time. You can also check your server logs for requests whose user-agent string contains "Qualys". Look for repeated checks of the same pages or endpoints at regular intervals. Because Qualys does not publish a verification method, any client can claim its identity and a log match is only a clue.
How Is Qualys Different From Other Qualys Agents?
Qualys operates separate agents for different purposes, so each agent should be evaluated and controlled independently.
