Firewall control and network safeguarding with PRTG


The stability of the network firewall is responsible for the protection of both the processes which are running as well as sensitive data. It is of the greatest importance to corporate security that the firewall be stable. IT service interruptions can paralyze the company, while the theft of company figures, future plans, and customer data can have unforeseeable consequences. It is all the more vital, therefore, that the firewall remains uninterrupted and always up to date.

With PRTG Firewall Monitoring, you get a series of sensors which makes monitoring your firewall straightforward and effortless. Enjoy a clear overview of inbound and outbound network traffic, and be informed immediately in the event of a crash. This will enable you to promptly take action to restore the security of your system.

In addition, PRTG constantly checks for firewall updates - for outdated firewall software is synonymous with a threat to security. 

Thanks to PRTG, the entire staff can work with peace of mind.

How Firewall Monitoring with PRTG works


PRTG Firewall Monitoring works jointly with most routers and firewalls. Cisco, Draytek and Bintec systems are supported. Also LANCOM and Windows Servers, as well as all other SNMP-compatible devices. SNMP is used most of the time, but for Cisco ASA firewalls, NetFlow technology is employed.

NetFlow offers a much more detailed analysis of bandwidth traffic than SNMP. While both SNMP and NetFlow show how much traffic the firewall filters, NetFlow can also indicate the most used connections and protocols and most active senders.

PRTG Firewall Monitoring can be configured in a matter of minutes, after which time the safeguarding of your network will be up and running. In the event the firewall is down or unusual activity is detected, PRTG will immediately send you an alert by email, SMS, or push notification.

Notification System 
Responsive alerts



PRTG features a variety of memory alerts: E-mail, SMS, Pager, Apps, running an external application, etc. You can specify when and how each person is to be informed. To do so, you can add contacts and edit, delete, or pause your notifications at any time.


The notification system is built into our firewall monitoring software. There are no additional costs.

And because the alarm feature is integrated, it only takes a few clicks to set it up.



PRTG won't wait until the firewall is "on fire" before notifying you. You set your own threshold values. If these are exceeded, you'll be informed accordingly.

You can therefore intervene quickly, before employees and customers notice something is wrong.
