Centinel publishes 186-page primary-source analysis of Kasada, DataDome, Castle landing pages
A forensic analysis of the top three agent-trust vendor landing pages, built on a custom tls-client scraper that cleared DataDome protection on DataDome's own site. The report documents a category shift from bot management to agent trust, 2025 through early 2026.
What the scrape captured
The research doc at docs/research/2026-04-20-kasada-datadome-castle-landing-analysis.md runs to 186 pages and pulls every public page on datadome.co, kasada.io, and castle.io that Google has indexed. The scraper was written in Go using a tls-client library that reproduces a real Chrome 131 TLS handshake and HTTP/2 SETTINGS frame. It cleared DataDome's own anti-bot stack on its own marketing site without a CAPTCHA challenge, on the first request, using default configuration.
What the landing pages reveal
DataDome publishes its pricing. Kasada runs a single-page funnel ending in a demo form. Castle operates a developer-first mini-site with code samples before any pricing discussion. 48 percent of DataDome's English pages are customer stories with a metric in the slug, not feature pages. Every page on DataDome ends with a standardized five-CTA block repeating the same calls to action in the same order. A fixed seven-H2 guide template drives their SEO volume: definition, how-it-works, examples, detection, prevention, comparison, FAQ, in that order, across hundreds of pages.
What the category language shift looks like
From January 2025 to April 2026, DataDome replaced the phrase bot protection with agent trust management on their homepage. Kasada replaced attack mitigation with agent verification. Castle kept the developer framing but added an agents page. The shift happened within a four-month window late in 2025, synchronized across all three vendors, which tracks with the rise of ChatGPT-User and agentic browsing traffic on publisher sites.
What Centinel does differently
The research exists because the Centinel positioning diverges from the three vendors. DataDome and Kasada sell to security teams at enterprises. Castle sells to product engineers. Centinel sells to publishers and content owners, and treats agent traffic as potential revenue rather than potential loss. The report names where each vendor's framing leaves publishers under-served and where Centinel fills the gap.
