You should be restricting NTLM

There is a security issues that most people do not know
about .. That when you share a file in zoom  and other products, your computer can passes your NTLM security credentials,

There is a GPO that should be set to only pass NTLM inside your
domain

Called Network security:
Restrict NTLM: NTLM authentication in this domaim

Security considerations

This section describes how an attacker might exploit a feature or its configuration, how to implement the countermeasure, and the possible negative consequences of countermeasure implementation.
NTLM and NTLMv2 authentication is vulnerable to a variety of malicious attacks, including SMB replay, man-in-the-middle attacks, and brute force attacks. Reducing and eliminating NTLM authentication from your environment forces the Windows operating system to use more secure protocols, such as the Kerberos version 5 protocol, or different authentication mechanisms, such as smart cards.

Vulnerability

Malicious attacks on NTLM authentication traffic resulting in a compromised server or domain controller can occur only if the server or domain controller handles NTLM requests. If those requests are denied, this attack vector is eliminated.

Countermeasure

When it has been determined that the NTLM authentication protocol should not be used within a network because you are required to use a more secure protocol such as the Kerberos protocol, then you can select one of several options that this security policy setting offers to restrict NTLM usage within the domain.

Potential impact

If you configure this policy setting, numerous NTLM authentication requests could fail within the domain, which could degrade productivity. Before implementing this change through this policy setting, set Network security: Restrict NTLM: Audit NTLM authentication in this domain to the same option so that you can review the log for the potential impact, perform an analysis of servers, and create an exception list of servers to exclude from this policy setting by using Network security: Restrict NTLM: Add server exceptions in this domain.
