Yesterday we looked at a little history on enterprise firewalls. Now let’s get back to early 2000s.

They wanted to upgrade and future-proof their ATM network with a secure solution that would have the flexibility to adapt to coming infrastructure and connectivity modernization.
Specifically, they envisioned a firewall at each ATM, connected via a secure VPN network using the internet, with comprehensive, updatable security filtering. They wanted ethernet connections, but they also wanted to be able to failover to modem/landline if needed. And ideally, a 3G wireless modem to use as a last-resort failover connection.
