Accessing QuickBooks Desktop via VPN

Hello,

I am currently using QuickBooks Desktop (QBD) version 24.0.  I access QBD from home via VPN.  My IT person is recommending me that it is best not to access QBD via VPN and is saying that accessing QBD via VPN will slow down the performance and may corrupt the QBD file.  Do you agree?  Thanks!
