No. SiteGrade performs real network analysis — actual SSL handshakes, live HTTP requests, DNS resolution, and HTML parsing. No AI, no estimates, no guessing. Every data point comes from testing your site directly.
Typically 5-15 seconds depending on the target site's response time. SSL checks, DNS resolution, and HTTP requests all happen in parallel where possible.
