The solution has a single price for unlimited assets. Value wise, the solution is also great for pen testers and consultants. The solution is useful for vulnerability and patch management from both the internal and public facing sides. Quick assessments, compliance scores, and results are provided without having to do agents.

Tenable Nessus could include a broader range of IT assets. Nowadays, IT is not limited to laptops and desktops. It can be any environment in the organization, such as iOS or Android mobile phones. Apart from that, organizations use APIs and specific tools. We would like Tenable to cover every aspect of IT infrastructure, not just generic systems like laptops, desktops, switches, or servers. It should include every kind of device, like Raspberry Pi. This small chunk of devices acts as sensors in several organizations. We would like to be able to scan every device in the network, and the solution should present vulnerabilities within their system.

The setup is quite straightforward and simple. I wouldn't describe the process as overly complex. The deployment time depends on how the endpoints are distributed. If it is a single one within one country and one region, it is very fast. We can do it in less than three months.

Valuable Features

Tenable Nessus offers valuable features including robust vulnerability scanning and detection, remediation suggestions, comprehensive reporting, and vulnerability prioritization. Its ease of use, user-friendly interface, and flexibility enhance its usability. It integrates well with other tools and provides fast, reliable results across various platforms. Its affordability, scalability, and up-to-date database are appreciated by users for effective management and assessment tasks, making it a preferred choice for vulnerability assessments and compliance checks.

"It notifies us of vulnerabilities as they arise, allowing us to respond quickly without manual intervention."
"You can then direct your team to create a report on the discovered vulnerabilities."
"We have around 500 virtual machines. Therefore, we conduct monthly scans and open tickets for our developers to address identified vulnerabilities. These scans cover the servers, other network equipment, and appliances in our infrastructure."

Room for Improvement

Tenable Nessus needs improvements in reporting functionality, including customization and integration capabilities. The user interface and graphical interface require enhancements for better usability. Cloud deployment features and accurate vulnerability detection, particularly for web applications, are lacking. Pricing and license flexibility are concerns. Tenable Nessus has issues with automated scanning and role-based access control. False positives and outdated remediation recommendations need addressing. Performance on system resources and user management functions could be optimized. Security updates and device scanning breadth should be expanded.

"The product could have unique features similar to one of its competitors."
"Tenable Nessus could include a broader range of IT assets."
"One significant drawback we encounter is the tool's tendency to flag patched packages incorrectly. For instance, if a package is patched by Debian maintainers but not updated to a major or minor version, Nessus may still flag it as vulnerable based on its database. This discrepancy leads to false alarms and requires our developers, system admins, and DevOps teams to address them."

ROI

Users highlight that Tenable Nessus significantly reduces vulnerabilities, preventing costly attacks. It fulfills essential security requirements by providing proactive scanning and issue detection, making it comparable to an insurance policy. The tool offers strong return on investment by enhancing visibility, enabling timely patch deployments, and achieving vulnerability management goals. Nessus improves cost and time efficiency, with many users rating its return at five out of five for its capabilities and benefits.

Pricing

Enterprise users find Tenable Nessus pricing to be competitive, though opinions vary by region and organization size. Users appreciate the affordability relative to features, especially for small and mid-sized businesses, and note fixed annual licensing costs without hidden fees. While some cite high costs, others benefit from flexible licensing options and consider it a sound investment, often comparing favorably to competitors. Discounts are appreciated, but more flexibility in asset management and pricing could enhance value.

"The product pricing is dynamic and varies based on the specific needs of each project and customer."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"The product is free."

Popular Use Cases

Organizations primarily use Tenable Nessus for vulnerability management, internal and external network scanning, and security assessments. They deploy it to evaluate security posture during mergers and acquisitions, scan for vulnerabilities in servers, workstations, databases, and web applications. Nessus assists in compliance tracking, remediation planning, patch management, and real-time monitoring. Users conduct scheduled assessments and address identified risks to maintain a secure environment and ensure compliance through regular vulnerability scanning and reporting.

Service and Support

Tenable Nessus customer support is responsive and helpful, with quick resolutions mentioned by many users. Some note efficient response times, although a few describe delays. Users appreciate the support for user interactions, with specific critiques regarding API documentation and license handling. Most find tech support reliable, praising the team for assistance with configurations and critical inquiries. Some indicate a lack of need for support due to successful internal management and training received.

Deployment

Users found Tenable Nessus's initial setup simple and intuitive. Many mentioned it involved downloading and running the software in a short time. Some appreciated guidance from Tenable or partners, while others noted it was helpful but not always necessary. Those with diverse systems experienced varying levels of complexity, often related to network configurations. Several users highlighted that deployment took from a few hours to a few months, depending on their specific needs.

Scalability

Tenable Nessus can handle scalability according to different user needs. It may suit medium-sized enterprises but faces challenges with large-scale deployments. Users commend its scalability within specific environments but encounter issues with cloud bandwidth and data retention. It allows scaling by adding licenses or nodes as needed. Scalability is largely determined by hardware capabilities and license agreements, catering to a variety of user scales from small teams to larger enterprises with multiple devices and locations.

Some mention initial configuration challenges or update frequency causing delays. Stability ratings range from seven to ten out of ten, with users emphasizing its reliability in different environments.
