It pops up now and then: Why should you not run #Wireshark as Administrator/root. There are quite a few reasons for that, but a very good discussion about this topic has been written quite a while ago by @PacketJay and I just wanted to bring it up again:

To all the IT staff at #hospitals out there: do me (and more than that, yourself) a favor and put mandatory MFA on your VPNs *now*. If you think that's expensive there is something even more expensive in orders of magnitude: #ransomware guys using your VPN to encrypt you.

Or to put it into another argument: A span port will show you what it will let you see and what you might have unknowingly configured, a TAP will show you what you want to see.
Especially if you want to play around with physics layer staff, TAPs are the only way to go.
We often need a closer look at the packets to find out what’s happening on the network. When it comes to 𝗧𝗔𝗣 𝘃𝘀 𝗦𝗣𝗔𝗡, there are substantial differences that you should know about.
