The starting point
Every administrator is faced with the task of developing a central security plan for their company. Part of this plan involves ensuring the various security levels in the firewalls, routers, and switches are properly set. There are network security tools for this purpose, but such tools tend to be extremely expensive.
PRTG is part of your security architecture. Our network monitoring software monitors your firewalls, ports, routers, switches, servers, and much more. With PRTG, you can rest assured that your network is secure. By thoroughly monitoring your hardware, software, and traffic, you’ll quickly identify irregularities in your network. Our motto: Better safe than sorry!
Five practical network security examples:
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.

Monitoring the firewall
The firewall is the network’s main tool for warding off attacks. If your firewall is not configured properly or is down, then all gates to your network are open. PRTG immediately lets you know if this is the case so you can quickly take action. To ensure the reliable monitoring of your network, PRTG comes equipped with both SNMP and NetFlow sensors, as well as user-defined sensors such as the HTTP XML/Rest Value Sensor. More on firewall monitoring.
An attack on your IT infrastructure can cause an unusually large amount of data to flow through your network. One of the ways that PRTG picks up on this anomaly is with its Packet Sniffing Sensor, which automatically compares values with historical data based on the time of the day and the day of the week. In turn, the software automatically displays an “unusual” status, and sends the administrator an alert so something can quickly be done to fix the problem.
A security loophole exposes your network to hackers all over the world. But not with PRTG: The Windows Update Status Sensor immediately informs administrators if a new update is necessary, and identifies which network computers are causing security loopholes due to unpatched Windows versions. Windows monitoring not only pays dividends, but also saves an enormous amount of time and frustration.
Open ports are necessary, but at the same time dangerous. They are used, for example, to access a network illegally or introduce Trojans. With PRTG, you will always see which TCP ports are open and which ones are closed. This information is vital, for often ports are only used on a temporary basis. Port monitoring lets you work with peace of mind.
Virus scanner update
Even the best antivirus scanner software is of no use if it is outdated or down. Use PRTG’s WMI Security Center Sensor to monitor the status of antivirus software on the clients in your network.

A constant eye on software
PRTG is comprehensive monitoring software that lets you monitor all your software and hardware.
Prompt, customizable alarm
PRTG’s built-in alarm feature is fully customizable. Choose your own threshold values and how you’d like to be informed.
Historical data for comparison
Every PRTG sensor is equipped with an “unusual” sensor status, and will automatically sound the alarm if values emerge which are inconsistent with previous ones. Such values may be indicative of security problems.
Compatibility with all the big manufacturers
PRTG is compatible with all the major software and hardware manufacturers. Along with its custom sensors, PRTG offers special pre-configured sensors for a variety of different manufacturers.
APIs for individual customization
PRTG’s documented APIs allow you to use the monitoring tool for your own individual scenarios. PRTG is therefore perfectly suitable for any network.
A centralized monitoring solution
PRTG is a centralized monitoring tool. Gone are the days of juggling several different tools at once. PRTG’s central switchboard provides the overview you need.
Practical tip: “Hey Christian, why is network monitoring important?”
“Instead of working directly on the “front line” like a virus scanner, network monitoring is more of a security command center that keeps an eye on the overall picture. It can monitor existing security software and ensure it is online, and at the same time search for activities that are flying under the radar.”
Christian Twardawa, COO of Paessler AG

The five levels of meta-security
In our meta-security section, we provide detailed information on how to systematically ensure network security and thus create a double layer of protection. Find out more about the five levels of meta-security here.
PRTG sensors for meta-security
SNMP allows you to monitor the traffic on your devices. The SNMP Custom Sensor can be configured to meet your own specific needs.
PRTG’s Packet Sniffer Sensor lets you monitor traffic in detail. This sensor, too, comes in a customizable version.
WMI Security Center Sensor
Use PRTG’s WMI Security Center Sensor to monitor the status of your Windows security tools.

PRTG and the
There are many different firewall manufacturers. Administrators are tasked with finding a monitoring tool that can verify that the firewall is online and that it is not displaying any unusual values.
PRTG is compatible with all the major hardware manufacturers, and comes with SNMP, NetFlow, and other user-defined sensors which can monitor them. You may therefore set up Juniper firewall monitoring, Cisco firewall monitoring, or Dell firewall monitoring – just to name a few.
Other firewall manufacturers, including Barracuda, Checkpoint, Fortinet, gateprotect, F5, Clavister Wolf, and Secure Point, can also be monitored by PRTG, as long as they support a protocol such as SNMP. This you will need to determine on a case-by-case basis.
PRTG’s knowledge base contains a few examples: simply enter the name of your firewall manufacturer in the search field and browse the reader questions and articles that are returned. Of course, you can also reach our technical support department directly via the knowledge base, or share your own experience by creating a new thread.
Over 95% of our customers recommend PRTG
Paessler AG worldwide trialled PRTG in over 600 IT departments.
The aim was to tune the network monitoring software closer to the needs of the administrators.
The result of the survey: over 95% of the participants would recommend PRTG - or already had.
Network security questions
iBandwidth is measured as the amount of data that can be transferred from one point to another within a network in a specific amount of time. Typically, bandwidth is expressed as a bitrate and measured in bits per second (bps). It refers to the transmission capacity of a connection and is an important factor when determining the quality and speed of a network. Read more ...
Is network security necessary?
According to a PAESSLER AG survey, identifying and eliminating IT loopholes is one of the main functions of administrators in medium-sized companies. 58% of those surveyed designated this task as their #1 job. Uptime and ensuring adequate bandwidth came in second and third place in our survey.
How do I get the required budget?
Be sure to present the issue to management in a clear-cut manner so they fully understand the risks. Calculate the cost of downtime beforehand. By doing so, you’ll increase your chances of receiving funds for good hardware and monitoring.
Which network security tools are available?
There are several different network security tools on the market. One of these is Nmap. Although PRTG is inherently not a network security tool, it indirectly serves to keep your network secure. By monitoring your software and hardware, PRTG provides you with an added layer of security. You’ll ensure your network is secure by being “better safe than sorry.” Network security tools range in price, from free to exorbitantly expensive.
Should we perform a penetration test?
Many administrators periodically test their network security by way of paid or internally-executed attacks. A penetration test is useful for detecting possible security loopholes. As a result, you will get a good idea of the areas which can benefit the most from detailed PRTG monitoring.
