Why? My router has one

You are correct!

But these devices are not learning engines or have the ability to block certain traffic. These firewalls are simple in that they work on ports only, not the actual traffic meaning hackers can use allowed ports to attack you.

What can I do about this?

We are currently working with some of the big names in security to be able to bring a competitively priced advanced firewall product into our portfolio. Once this is done we will have a fully managed intelligent firewall service we can offer that is fully monitored.

What will this cost?

We are still working on this, there are many systems out there with many different pricing points. We are testing these products to see what works best, can be used within customer environments as well as the cost implications.

Currently, this is a TBC part which we hope to answer soon.
