Trellner Research publishes independent reports on AI search engines—a niche but useful topic. The site itself looks professional: there's an about page, contact information, and a clear description of what it does. Security is solid with HTTPS and Cloudflare protection. So why 'Use Caution'? The domain was registered just four days ago. That's the biggest red flag here. Legitimate research outlets can start fresh, but a brand-new domain means no reputation, no track record, and no way to verify claims through history. Scammers also love new domains. For now, trellner.com appears to be what it claims: a research blog. There's no e-commerce or data collection that would raise compliance concerns. The missing privacy policy is normal for a site like this. But you should treat any information from a site this young as unverified. If you're reading their reports, double-check sources elsewhere. If they ever ask for money or personal details, pause. The site may be genuine—but it hasn't earned the benefit of the doubt yet. Keep an eye on it as it ages; if it's still around in six months with consistent output, that will be a much stronger signal.
