Your audit tool, whichever one you're using, suddenly can't reach a client's site — and the crawl either fails outright or comes back with a page full of "please verify you're human." This isn't the tool's fault, and it isn't really fixable from the tool's side either.
Services like Cloudflare, Akamai, and Imperva sit in front of a website and inspect every incoming request before it reaches the site itself. They're specifically designed to detect automated traffic — real fingerprinting signals like browser automation flags, unusual request patterns, or a User-Agent string that doesn't match a normal browser. When one of those triggers, the visitor (human or not) gets served a "checking your browser" interstitial instead of the real page.
This is the bot-protection service working exactly as intended. It isn't a bug in it, and it isn't a bug in whatever crawler got blocked.
It's technically possible to make an automated browser harder to fingerprint. We do some of this ourselves, for the legitimate reason that a real audit needs to see what a genuine visitor sees — not evade detection for its own sake, but avoid being wrongly flagged while doing something completely legitimate (auditing a site with permission).
What we won't do, and what you shouldn't rely on either, is actively defeating a real challenge a site has deliberately put up — solving CAPTCHAs, bypassing verification screens, anything of that nature. Beyond the ethical line, it's also an arms race you'll keep losing: bot-protection services update their detection constantly, so anything built to beat them today breaks again next month.
It has to happen on the website's side, not the audit tool's side — because only the site owner can tell their own security service "this specific traffic is authorized."
Detect it, and say so plainly — "this site's bot-protection blocked us" — rather than silently scoring a block page as if it were the real site. A report generated against a "verify you're human" interstitial isn't a real audit of anything, and a tool that doesn't distinguish the two is giving you findings you shouldn't trust.
We built exactly this detection in — if a site's bot-protection blocks us, you'll know, not get a misleading report.
