PRODUCT OVERVIEW

Don’t gamble with securing your network 

Security issues on your network can have disastrous consequences not only for your IT infrastructure, but for your entire business. Even the best firewalls are no guarantee of total IT protection.

Misconfigurations, unnecessarily open ports, and malware not only compromise the internal network, but also present a serious threat to overall IT security.

A vulnerability assessment, or a penetration test (pentest), can identify potential security gaps in applications or apps, operating systems like Windows and Linux, and hardware such as switches and routers. It does not matter whether the systems are on-premises or in the cloud.

Our all-one-one network monitoring tool Paessler PRTG helps you to uncover and eliminate security vulnerabilities in your IT infrastructure!

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

Scan network vulnerabilities: FAQ

 

What is a network vulnerability scanner?

Network vulnerability scanning or vulnerability detection automatically scans networks for security gaps and vulnerabilities. It uses databases of known vulnerabilities to identify potential risks and generates reports with recommendations for solving these issues. The scanner inventories network devices, checks configurations, and prioritizes vulnerabilities based on risk. It can run periodic vulnerability tests and integrate with other security tools to ensure continuous network security.

PRTG as a network vulnerability scanner scans all devices and applications in your network at defined intervals and notifies you of potential risks that may exist.

What are the features of a good network vulnerability scanner?

Good network vulnerability scanning tools should possess a range of features to effectively identify, analyze, and manage security vulnerabilities in a network. Here are some of the key features to look for:

1. Comprehensive scanning:

  • Ability to scan a wide range of devices and operating systems.
  • Support for different network types (e.g., wired, wireless, cloud environments).
  • Capability to detect various types of vulnerabilities, including software flaws, misconfigurations, and missing patches.

2. Accuracy:

  • High detection rate with minimal false positives and false negatives.

3. Customization and flexibility:

  • Customizable scan settings to target specific devices, IP ranges, or network segments.
  • Ability to schedule scans at convenient times to minimize network disruption.

4. User-friendly interface:

  • Intuitive and easy-to-navigate user interface.
  • Clear and detailed reporting with actionable insights.
  • Visualization tools to help interpret scan results (e.g., dashboards, charts).

5. Integration capabilities:

  • Seamless integration with other security tools, such as SIEM (Security Information and Event Management) systems, ticketing systems, and patch management solutions.
  • API support for custom integrations and automation.

6. Real-time monitoring and alerts:

  • Continuous monitoring for new vulnerabilities and real-time alerts.
  • Notification system to alert administrators of critical vulnerabilities as soon as they are detected.
What is intrusion detection?

Intrusion detection is the monitoring and analysis of computer systems or network activity to identify unauthorized access or security breaches. Techniques include network-based and host-based monitoring, as well as signature and anomaly detection methods. One challenge in intrusion detection is managing false positives, which are false alarms that indicate a potential threat that is not actually present.

PRTG helps you with intrusion detection by monitoring network traffic and cloud-based web applications, and using an analyzer to detect suspicious unusual activity or potential cyberattacks in real time.

What is comprehensive vulnerability management?

Vulnerability management is the systematic process of identifying, assessing, and troubleshooting security vulnerabilities in systems and networks. It involves scanning for vulnerabilities, prioritizing them based on severity and impact (such as CVEs - Common Vulnerabilities and Exposures), and solving them with patches or security controls.

PRTG tracks the status of security patches and updates on network devices and servers, and identifies new devices connected to the network.

What is access control monitoring?

Access control monitoring oversees and regulates who can access specific resources, data, or areas within a system or organization. It continuously monitors user activity, permissions, and authentication processes to ensure compliance with security policies and detect unauthorized access attempts. In addition, cybersecurity and automation play a critical role in enhancing these monitoring processes, streamlining response actions, and reducing the risk of human error.

PRTG monitors user access to critical systems and resources and detects unauthorized access attempts.

What is asset management?

Asset management is the process of identifying, inventorying, and controlling all devices that have access to an organization's network and resources. This includes maintaining a comprehensive inventory, implementing access controls, and monitoring device activity for compliance with security policies.

PRTG helps you with your asset management by keeping track of all network devices and their configurations to ensure that only authorized devices are connected to the network.

What is compliance monitoring?

Compliance monitoring is the ongoing process of tracking, assessing, and ensuring conformance to regulatory requirements, industry standards, internal policies, and best practices. It systematically monitors activities, processes, and controls to verify alignment with compliance frameworks and policies.

PRTG monitors network activities to ensure compliance with industry regulations and standards such as GDPR, HIPAA, PCI DSS, etc.

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.
