You may be right, and I'd be happy to ignore it, but unfortunately, my work laptop has baked it in. I assume many other companies are using it as well.
What I'm saying is that I can't access this website from my work laptop - it shows me branded blocked page.
I'm not 100% sure, but I think there is a policy set up on Zcaler, blocking access to the domains defined in some sort of blacklist. The reason why I assumed it's UCEPROTECTL3 is because it's the only positive result I got at online blacklist lookup against gmnz.xyz.
And no, I don't feel comfortable sharing my employer.
