At-scale software development processes are inherently prone to discrepancies and drawbacks.
While some production hiccups are inevitable, they cannot be left to cause system vulnerabilities that affect product performance and user experience. Vulnerability scanning is, therefore, an integral part of site reliability engineering (SRE) operations that a development team undertakes. The primary goal of this process is to identify all infrastructural, operational, and security-related vulnerabilities within a project and eliminate them before product roll-out.
Although standard code-testing tools can help with vulnerability scanning, they often fail to detect certain infrastructure and security vulnerabilities. Also, some complex vulnerabilities require techniques like heat mapping to estimate how much usage load a specific part of a system is expected to handle. It takes specialized vulnerability scanning tools to make a difference here. These tools are designed to stimulate real-world user-profiles and assess development projects holistically.
In this article, we’ll explore what makes a good vulnerability scanning tool and list five examples based on our extensive research.
What makes a good vulnerability scanning tool?
Apart from ease of use and integration, several other operational characteristics work to make a vulnerability scanning tool efficient. Here are some of the most important factors SRE teams should consider while choosing vulnerability scanning tools.
- Accuracy: A good vulnerability scanner must accurately identify and prioritize vulnerabilities based on their severity and impact. Higher accuracy ensures better development efficiency and higher production quality. False positives can waste valuable time and resources, while false negatives can leave critical vulnerabilities undetected.
- Coverage: The tool should have a broad range of code coverage capable of scanning multiple systems and platforms, including both on-premises and cloud-based systems.
- Customization: The ability to customize scans, reports, and alerts based on specific requirements and compliance regulations is crucial to meeting the unique needs of different organizations.
- Continuous monitoring: A good vulnerability scanning tool should offer continuous monitoring capabilities, allowing for regular scans and alerts for new vulnerabilities as they emerge.
- Reporting: The tool should provide comprehensive and actionable reports that are easy to understand and use, enabling administrators to prioritize and address vulnerabilities effectively.
Vulnerability scanning processes can only be as efficient as the SRE teams overlooking them. While most modern vulnerability scanning tools are highly automated, developers must be trained to use them effectively. That makes it crucial for businesses to conduct efficient onboarding processes every time a new vulnerability scanning tool is introduced to their tech stack.
Top vulnerability scanning tools
Here are our top five picks of vulnerability scanning tools currently available on the market.
Nessus is a widely used vulnerability scanning tool developed by Tenable Network Security. It is known for its fast and efficient scanning capabilities and the ability to detect a wide range of vulnerabilities, including:
- Software security vulnerabilities

Nessus integrates seamlessly with other security tools such as vulnerability management, patch management, and compliance management tools to provide holistic security solutions. It also offers a range of support options, including phone and email support and online resources such as a user forum, documentation, and knowledge base.
The platform offers a variety of pricing options, including a free version with limited functionality and several paid versions with additional features and capabilities. The pricing is based on the number of IP addresses being scanned and the level of support required, making it accessible to organizations of all sizes.
Overall, Nessus is a powerful and reliable vulnerability scanning tool that offers fast, efficient, and comprehensive vulnerability scanning for a wide range of operating systems and devices. Its advanced features, customizable scan policies, and integration capabilities make it the perfect tool for organizations with complex security needs.
Open Vulnerability Assessment System, or OpenVAS, was first released in 2005 as a fork of Nessus. The fork was initiated in response to Nessus’s switch to a proprietary license which made it difficult for many users to continue using the tool. OpenVAS was designed to be an open-source and free alternative to Nessus, providing the same level of comprehensive and customizable vulnerability scanning.
It is based on a client-server architecture, where the server performs the actual scanning of systems and the client is used to configure and manage scans. The server consists of a set of modules, each responsible for performing a specific type of vulnerability check. The modules are regularly updated to keep up with the latest vulnerabilities and attack techniques.
A key advantage of OpenVAS is its ability to scan multiple operating systems, including Linux, Windows, and macOS. It can also scan many network devices such as routers and switches, making it an ideal tool for organizations with complex network environments.
OpenVAS is a community-supported tool, which means that it has a large and active user community that provides ongoing support and development. Users can access online resources such as documentation, forums, and knowledge bases and receive support from the community.
Finally, OpenVAS is a free tool that is accessible to organizations of all sizes, including small and medium-sized businesses. It does not offer the same level of support and features, however, as commercial vulnerability scanning tools.
