Adaptability
You can adapt the Security Engine to any environment and situation dynamically. You just need to enable the features that best fit your new needs.
For example, if you change your network architecture for site-to-site connectivity from a leased line to VPN technology, you can easily enable the VPN feature on the Firewall by upgrading your license. Or if your host servers in the DMZ protected by the Firewall, you can enable deep inspection on the Firewall to prevent attacks on these servers.
