This is the scenario: 2 networks, one whith servers plus firewall, other with users and firewall to access to servers. We pretend something like give a card or key to the user to access to remote servers and when is gone (out), key or card return to us.
Any hardware/software that anybody knows?
When i say card or key something physical. Has Cisco something like this?
If not, anyone knows where can i found something?
