PRODUCT OVERVIEW

”PRTG helps us monitor critical security systems to give customers the peace of mind that their devices are operational and protecting their valuable assets.”

Rob Jackson, President
Integrated Precision Systems

“When it comes to security, we do of course use classic tools such as firewalls, virus scanners, and intrusion detection systems. However, these are no longer enough today. PRTG provides for additional security by detecting unusual behavior which may be a sign that a hacker has outsmarted our security systems.”

Damir Karacic, IT Administrator
Noris Inklusion

“Monitoring with PRTG is crucial for security. Today’s threats can move low and slow, so in addition to looking at the usual suspects, you also need to keep tabs on other indicators. For example, if a server is running a peak capacity for no apparent reason, you want to know so you can take a look and see what’s up – for example an open connection that is being used to extract data in a ransomware attack.”

Jon Larsen, CIO
Richweb

“The best thing about PRTG is that it provides for simple and effective monitoring, all the while respecting the security requirements of manufacturers. PRTG is so easy to use, that many of our monitoring tasks are now handled by our interns. We will definitely expand our use of the software in the future.”

Karsten Boettger, Head of IT

Anomaly Detection Monitoring: FAQ

 

What is anomaly detection and when should I use it?

Anomaly detection is the process of identifying unusual patterns or behaviors in data points that deviate from the expected norm. In network monitoring, anomaly detection techniques help identify traffic spikes, potential security threats, or abnormal behavior before they lead to major issues. You should use anomaly detection when monitoring complex networks or IT infrastructures where undetected anomalies could result in security breaches, performance degradation, or costly downtime.

How does PRTG perform anomaly detection in networks?

PRTG anomaly detection works using various preconfigured sensors like SNMP, flow (NetFlow, sFlow), and packet sniffers to automate monitoring metrics like network traffic, device performance, and system resources. By analyzing the data these sensors collect in real time, PRTG detects deviations from normal network behavior such as unexpected traffic patterns or bandwidth hogs. The algorithm is used to compare normal behavior with historical data so that false positives can be avoided. The software then triggers alerts, allowing you to address potential issues proactively.

Why is anomaly detection important for network security?

Anomaly detection algorithms are crucial for network security because they help detect irregular behavior that could indicate cyber threats like Distributed Denial of Service (DDoS) attacks, unauthorized access, or data breaches. By identifying standard deviations in traffic patterns or user behavior, anomaly detection systems can flag potential security risks early.

What types of anomalies and correlations can PRTG detect?

PRTG can detect several types of anomalies, including:

  • Bandwidth spikes: Unusual exceeding of thresholds in network traffic may indicate bandwidth misuse or security threats.
  • Device performance issues: Sensors can detect excessive CPU or memory usage, which could signal a failing compute device.
  • Network latency: Increased response times detected by Ping sensors could be the baseline to connectivity problems.
  • Unusual traffic patterns: Flow sensors (NetFlow, jFlow, sFlow) can identify suspicious communication between devices that might indicate an attack or misconfiguration.
How can anomaly detection with PRTG improve network performance?

By monitoring metrics like network and device performance in real time, anomaly detection with PRTG allows you to spot potential bottlenecks, overused resources, or inefficient configurations. These datasets enable you to adjust bandwidth usage and fine-tune system settings to enhance overall performance and stability.

What is a sensor in PRTG?

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

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
