Proton

Borderline visible. AI bots can crawl Proton, but the structured-data signals are thin - you are at real risk of being skipped when buyers ask ChatGPT, Claude, or Perplexity for a recommendation.

About Proton
from our crawl and measurement
Proton: Privacy by default is a Plan-les-Ouates, Geneva business whose own site puts it this way: "Over 100 million people use Proton to stay private and secure online. Get a free Proton account and take back your privacy." When AI engines look at it, they find little to work with. It scores 4.7 out of 10.
Our crawl found structured data on the page (WebPage, Corporation, WebSite) and a readable heading structure. It is missing an llms.txt file and a sitemap.
