Just ask if anyone that works for SAP is able to log-on to the SAP server using any other provider than Rogers or bell. Maybe that would clarify. I don't mind if you say SAP.
IMHO, no one from SAP should be or is likely allowed to comment on their remote security measures. I know my company doesn't allow it. I work for a competitor to SAP.
As already mentioned, it is up to SAP's IT to implement the remote security measures and protocols. The local ISP is not normally involved unless they are blocking specific ports that prevent some protocols from working. There is sometimes a higher subscription fee for home business users rather than simple personal use.
I know that my company provides all VPN (with local network blocking), Firewall, Anti-Virus etc.
