In addition to equvinox (hey again):
In enterprise networks you should rely on 802.1x or what's also valid use case is the use of ipsec to ensure the local client connection is "safe".
Some 802.1x have inherent mitm attacks that have been called out since 2004 and never got the v2 (https://www.rfc-editor.org/rfc/rfc6677.html). EAP-TLS however is the best practice here + VLANs.
