Phishing email? - Important: Palo Alto Networks Informational Security Bulletin

[CraigAr]

I just received what looks like an official PA email which suggests I visit (which appears to be legit)
https://security.paloaltonetworks.com/PAN-SA-2024-0015

For important security information about how to configure my management interface.

Yet when I look at the link I'm being asked to click, I see something which doesn't look at all related to Palo Alto (don't click this, might be bad):

https://u574567.ct.sendgrid.net/ls/click?upn=u001.Mf7MWdPSfie6Atm1eagsgHU9XR5iD9zXZRfCa5aUs7TUinpGHG... 
I changed the last letter from a 'D' to an 'A' in case someone does try to click despite my warning.

Is this real?  Or is it Phishing?
If it is real, why the red-herring style obfuscated link? [Phishing? Or tracking I don't want?]

Why would a highly targeted security company send me something like this which I won't use because it looks like a security threat?

If you want me to read and apply, don't load it up with a garbage payload.
