Executive SummaryUpdated on Oct 9, 2024

Acunetix and Tenable are key competitors in the vulnerability management category. While Acunetix excels in web application capabilities, Tenable holds an advantage for enterprise-level needs due to its integration and scalability.

Features: Acunetix offers a web-based interface, powerful scheduling capabilities, and an Interactive Application Security Testing module. It provides comprehensive reporting, is easy to set up, and maintains a low false positive rate. Tenable boasts extensive integration options with third-party tools, strong cloud management features, and supports both on-premises and cloud environments. Its large vulnerability database enhances network security coverage, but it lacks some depth in web application scanning.

Room for Improvement: Acunetix could enhance tool support redundancy, lower false positives, and improve mobile environment integration. Manual replication capabilities and user interface flexibility are additional areas for improvement. Tenable could simplify its dashboards, reduce setup complexity, and offer better pricing structures. Speed in support response and application testing enhancements are also necessary improvements.

Ease of Deployment and Customer Service: Acunetix is known for its simple deployment across various platforms, receiving positive customer service feedback with 24/7 support. Tenable provides a wide array of cloud options, praised for responsive technical support and accommodating feature requests. Acunetix maintains a strong lead with its user-friendly setup and customer service.

Pricing and ROI: Acunetix's recent price increases necessitate a reassessment of its cost-effectiveness despite its high initial value. Tenable, although also costly, offers a pricing model tailored for large enterprises. Both tools deliver ROI through enhanced security posture and risk management, but a reevaluation of their pricing strategies is suggested for current market competitiveness.

Setup Cost

Acunetix pricing is seen as high and complex, impacting renewal decisions due to cost transparency and fluctuation issues.

Tenable Vulnerability Management is costly, with prices from $2,300 to $137,000, suitable for enterprises but pricey for SMBs.

The pricing cost is affordable for small and mid-sized organizations, and when compared to Checkmarx, it is significantly affordable, as Checkmarx is quite expensive.

Featured Reviews

Rahul Kumar

Senior Engineer - Penetration Tester at a government with 10,001+ employees

Identifies vulnerabilities across bulk web applications but needs better support and cleaner reports

The best feature Acunetix offers is the centralized dashboard and the quality of reports it generates, which includes various options for selecting reports and developer options for directly sharing the reports with developers. The centralized dashboard of Acunetix gives visibility into the security aspects of mass applications; for instance, with more than 200 applications, it provides a valuable overview of findings and necessary fixes, along with a high-level summary that helps us achieve compliance through monthly and sometimes weekly scanning. In terms of reporting, Acunetix is excellent because it can generate different types of reports, such as an executive summary report, detailed reports, and developer reports that can be shared directly with developers. Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and OWASP. Acunetix provides a centralized report with compliance-related aspects and a vulnerability timeline, effectively helping reduce vulnerabilities and save time.

Have maintained accurate vulnerability scans and gained actionable remediation insights across thousands of servers

Tenable Vulnerability Management agents are very lightweight, and the results we get are very accurate. The solutions they provide to us, assuming if one vulnerability exists, there will be a solution. The resolution they give us in wording will be the best solution. The exploit rates and the reports we get provide a lot of information, making it very easy for us to verify.The main benefit of integration with Tenable Vulnerability Management is that there will be no lack of missing vulnerabilities when it comes to the patching environment. That is one of the key aspects of why we have integrated Tenable to our patching tools. It has a vast capacity of pushing the data to our tools due to its capability and compatibility. That is also one of the reasons why we are using Tenable Vulnerability Management.
