rmi.paccar.net is a login page for PACCAR, a major truck manufacturer. If you're an employee or partner, this is almost certainly the real portal — it's hosted on Microsoft Azure, uses a valid SSL certificate, and redirects to a Microsoft Active Directory Federation Services login. The site has no history of malware or blacklisting, and the security headers are well-configured.
What about the missing privacy policy and terms of service? For a dedicated login subdomain, these documents are usually on the main PACCAR website, not on this page. That's a small gap, but not a red flag for a corporate portal.
One thing to watch: always double-check the URL in your browser before typing your password. Phishing sites sometimes mimic corporate login pages, but the real rmi.paccar.net is a legitimate subdomain of paccar.net. If you were sent here by a suspicious email, verify the sender before proceeding. Overall, if you're a PACCAR user, this site is safe to use.
