Today, threats are not only limited to the internet. Organizations face guests and employees who connect their own equipment into the network or take company equipment home with them. A firewall with IPS capabilities, such as a next generation firewall, is a good first measure to protect against modern day threats, but they will only protect what goes in and out at the network perimeter.

That is why it is important to implement a strategy and solutions that are flexible scalable in order to continuously anticipate changes. In terms of security this can be done by combining the best of both worlds. Packet capture from the legacy world and self-learning flow monitoring from the digital transformation.
