Not All Trust Signals Are Equal
SSL certificates verify encryption. Legacy seals scan for malware. AI-Signed verifies everything — identity, security, content, reputation, and AI readiness — across 43 automated checks in a single trust score.

Why SSL Isn't Enough
An SSL certificate proves one thing: the connection between a visitor's browser and your server is encrypted. That's it. It does not prove who owns the site, whether the content is legitimate, whether security headers are properly configured, or whether the site is safe to do business with.
A phishing site can have a valid SSL certificate. A site with zero security headers, no privacy policy, no contact information, and a domain registered yesterday can have a valid SSL certificate. The padlock icon in the browser tells visitors nothing about the trustworthiness of the site itself — only that the connection is encrypted.
Search engines and AI chatbots know this. Google uses HTTPS as a baseline requirement, not a ranking differentiator. ChatGPT and Perplexity evaluate dozens of additional signals — security headers, structured data, content quality, domain reputation, AI-readable metadata — when deciding which sites to recommend. SSL is table stakes. It's the starting line, not the finish line.
Why Legacy Trust Seals Are Outdated
McAfee Secure (now TrustedSite), Norton Secured, and similar trust seals were designed for the mid-2000s web. Their primary function is malware scanning and PCI compliance verification — legitimate concerns, but a tiny fraction of what determines trust in 2026.
These seals don't check whether your site has security headers configured. They don't verify your identity through DNS ownership or email authentication. They don't evaluate content quality, structured data, or AI readiness. They have no concept of llms.txt, ai-plugin.json, or the signals that AI chatbots use to determine which sites to recommend.
They're also expensive. McAfee Secure starts at $300/year or more for basic scanning. Norton Secured costs even more. For that price, you get a badge that tells visitors "we scanned for malware" — but tells AI systems nothing about whether your site is trustworthy enough to cite as a source.
Perhaps most critically, legacy trust seals are static images. They're not machine-readable. An AI agent can't programmatically verify whether a McAfee Secure badge is valid — it's just a PNG on a page. AI-Signed badges are dynamic, verifiable through a public API, and readable by both humans and AI agents.
What AI-Signed Does Differently
Built for how the web works today — not how it worked in 2008.
Identity, technical security, content trust, reputation, and AI readiness — weighted into a single trust score with a letter grade.
Continuous monitoring, a dynamic trust badge, and a public verification API — at a fraction of the cost of legacy seals.
Trust badges are verifiable by AI agents through a public API. Not a static image — a programmatic proof of trust.
