Empowering Cybersecurity with Nessus

As cyber threats become more sophisticated, organizations need to stay ahead of the game by proactively monitoring their network for vulnerabilities and potential attacks. Threat intelligence is a critical component of any organization’s cybersecurity strategy, as it provides insights into potential threats and vulnerabilities, allowing them to take pre-emptive measures to protect their systems and data.

Nessus is a popular vulnerability scanning tool that can also be used for threat intelligence. In this article, we’ll provide a comprehensive guide to using Nessus for threat intelligence, covering everything from setting it up to analysing results and integrating it with other tools.

Setting up Nessus for Threat Intelligence Before you start using Nessus for threat intelligence, you need to install and configure it. Here’s how to get started:

• Download and install Nessus: Nessus is available for download from the Tenable website. Once you’ve downloaded the appropriate version for your operating system, follow the installation instructions provided.

• Configure Nessus: Once Nessus is installed, open it in your browser and follow the setup wizard. You’ll need to create an account, enter your license key (if you have one), and configure your scan settings.

• Create a new scan: Click on the ‘Scans’ tab in the Nessus interface and then click ‘New Scan’. Give your scan a name and select the appropriate scan template (e.g., ‘Basic Network Scan’).

• Configure the scan settings: In the ‘Scan Settings’ tab, you can configure various settings for your scan. For threat intelligence purposes, you may want to select a specific policy that focuses on detecting vulnerabilities that are commonly exploited by attackers.

• Schedule the scan: You can schedule your scan to run at a specific time or on a recurring basis. For threat intelligence purposes, we recommend running scans on a regular basis to ensure that you’re constantly monitoring for new threats and vulnerabilities.

Analyzing Nessus Results for Threat Intelligence

Once your Nessus scan is complete, it’s time to analyse the results. Here are the steps you should follow:

• Review the scan report: The Nessus scan report provides detailed information about the vulnerabilities and threats that were detected during the scan. Review this report to identify potential vulnerabilities and threats that require further investigation.

• Prioritize vulnerabilities: Not all vulnerabilities are created equal. Prioritize vulnerabilities based on their severity and potential impact. You may want to focus on vulnerabilities that are commonly exploited by attackers, or those that could lead to data breaches or system compromise.

• Investigate potential threats: Look for signs of potential threats, such as unauthorized access attempts or suspicious activity. Investigate these potential threats further to determine if they require further action.

Integrating Nessus with Other Tools for Threat Intelligence

While Nessus is a powerful tool on its own, it can also be integrated with other threat intelligence tools to enhance its capabilities. Here are some examples:

• SIEM integration: Nessus can be integrated with a Security Information and Event Management (SIEM) system to provide real-time threat intelligence data. This integration allows organizations to quickly detect and respond to potential threats.

• Incident response integration: Nessus data can be used to enrich incident response data. This integration allows organizations to quickly identify potential threats and take appropriate action to mitigate them.

• Threat hunting: Nessus data can be used for threat hunting activities, allowing organizations to proactively search for potential threats before they can cause harm.


Nessus is a powerful tool that can help organizations stay ahead of the ever-evolving cyber threat landscape. By proactively monitoring for vulnerabilities and potential attacks, organizations can take pre-emptive measures to protect their systems and data. The comprehensive guide we provided covers everything from setting up Nessus for threat intelligence, analysing results, and integrating it with other tools. By leveraging Nessus for threat intelligence, businesses can enhance their cybersecurity posture and gain valuable insights into potential threats and vulnerabilities, ultimately safeguarding their critical assets from cyber-attacks. It’s time to take control of your cybersecurity and empower your business with Nessus.
