Find websites with security and performance problems
Retainers are easier to sell than rebuilds, because the problem never goes away. Tellsign audits every business site in a niche and surfaces the ones running known-vulnerable code, broken scripts, or tracking that stopped working years ago.
What the scan flags
Every business in your niche and city, scored on the signals that matter for website maintenance and care plans.
Front-end libraries with published CVEs still shipping on the live site.
An insecure connection, or JavaScript throwing errors on every visit.
Legacy analytics with no modern replacement — they've been flying blind for years.
Pages blocking search engines outright, usually left over from a build that went live wrong.

Find websites with security and performance issues — FAQ
Every scanned site is audited for front-end libraries with known published vulnerabilities, whether HTTPS is enabled, JavaScript console errors, outdated analytics, missing mobile viewport, and pages that block search engines. Leads are ranked by how many of those they trip.
No — and the pitch shouldn't pretend otherwise. It's an outside-in health check of what a browser can see: vulnerable libraries, transport security, script errors, and neglect signals. That's exactly the evidence a care-plan conversation needs.
Redesign revenue ends at launch; a care plan renews. The same scan finds both, so you can lead with a security finding, open the relationship on a retainer, and let the rebuild follow once you're already inside the business.
