Union Pacific is a real railroad company with a history that goes back over a century, and its domain, up.com, has been registered since 1994. On the surface, that looks solid. But when we checked the site for basic security, we found a major problem: it doesn't use HTTPS. Every connection to the site is unencrypted, which means any login credentials or personal information you send could be seen by others. For a company that asks customers to sign in online, this is a serious gap. Most legitimate businesses today, especially those handling user accounts, encrypt their traffic as standard. The rest of the signals point to a genuine company β clean blacklists, transparent ownership, and legal pages all check out. But the lack of HTTPS on a site with a customer portal is hard to ignore. If you need to do business with Union Pacific, consider using their phone or a secure portal on a subdomain if one exists. For now, the main website raises real safety concerns for login use.
