What is firewall monitoring?


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In addition, PRTG constantly monitors for firewall updates - for outdated firewall software is synonymous with a threat to security.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

 

 i What is a sensor?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, e.g. the traffic of a switch port, the CPU load of a server, the free space of a disk drive. On average you need about 5-10 sensors per device or one sensor per switch port.

How Firewall monitoring with
PRTG works


PRTG Firewall Monitoring works jointly with most routers and firewalls. Cisco, Draytek, Fortinet 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.

 i NetFlow is a protocol for collecting, aggregating and recording traffic flow data in a network. NetFlow data provide a more granular view of how bandwidth and network traffic are being used than other monitoring solutions, such as SNMP. NetFlow was developed by Cisco and is embedded in Cisco’s IOS software on the company’s routers and switches and has been supported on almost all Cisco devices since the 11.1 train of Cisco IOS Software.

FAQ – Firewall monitoring

What kind of software can I use to monitor my firewall?

In general, you have two possibilities: you can use the monitoring systems of firewall providers, or you can use centralized monitoring software to monitor your firewall as well as your entire network. Nagios, ManageEngine, and PRTG are examples of such software. For more information, see our comparison of PRTG with our competitors.

Is PRTG a firewall
analyzer?

PRTG sensors monitor the status of your firewall and hardware parameters such as CPU usage. However, our sensors are not suitable for filtering and storing log files. Some software providers specialize in the analysis of firewalls. PRTG is often used in combination with their tools.

 

 

How can I monitor my routers and switches?

When your firewall sounds the alarm, it’s not always easy to identify the source of the problem. PRTG monitors your switches and routers around the clock to check for anomalies. It lets you keep an eye on your entire network.

Tutorial: Allowing PRTG through the firewall

Our monitoring software is often used in decentralized networks. It therefore comes with remote probes that connect to the core PRTG server. To use these probes, you must allow PRTG through your firewall. Learn how to do it here.

 

Notification system:
Be alerted quickly

 

 

Flexible

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

Integrated

The notification system is built into the monitoring software and is available at no extra charge. Because of its integrated quality, configuring the alert feature is done in just a few clicks.

Proactive

PRTG won't wait to let you know if your "house is on fire." You define your own thresholds. If these are crossed, you'll receive a corresponding notification. This means you can intervene promptly before clients or coworkers are aware of any problems.
