When a port is opened, who checks to see it was closed?
With our Change Detection system, we scan all external IP addresses looking for changes, and then report the differences. This way you can monitor to make sure your perimeter remains hardened.
One of our most common audit findings is that somebody changed a port on the firewall, temporarily, but did not return the port to it’s required state. Our change detection service solves that problem.
On a monthly (or weekly, if necessary) basis, you can check for changes in ports by subscribing to our Change Detection service!
