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.
It saves a significant amount of time by covering attack surfaces.
I have seen a return on investment, as Acunetix helps reduce the man-days and effort needed for scanning bulk applications through automated assessments.
I have seen a return on investment with Acunetix, including time saved and cost reduction, because it provides us threats on our web application servers.
For high-severity issues, they reach out within two to three hours, and for critical issues, a response is received within 15 minutes.
The technical support from Invicti is very good and fast.
Support staff not being familiar with the problem.
It needs improvement in response time and addressing feature requests promptly.
The technical support of Tenable Vulnerability Management is available 24/7, and whenever we require support, we can get it within five minutes.
We had used Tenable's expert support services in order to make sure that we run Tenable Vulnerability Management on a continuous basis and are able to utilize their services.
Acunetix can handle increasing workloads and more applications easily.
Acunetix's scalability for my growing needs is great; it is a very scalable product compared to others.
They can seamlessly scale the number of endpoints from 100 to 1,000,000 in a day.
Tenable Vulnerability Management is highly scalable.
With the growing needs of our company, Tenable Vulnerability Management is able to safely adapt.
I did not need to reach customer support because the product is very stable.
I have faced no stability issues with Tenable.
The stability is commendable, and I would rate Tenable ten out of ten.
The stability of Tenable Vulnerability Management is highly reliable.
The main concern is related to false positives; Acunetix needs to work on identifying valid and invalid findings.
Acunetix should have better integration with newer tools such as GitHub and Azure DevOps.
I believe Acunetix can improve customer support, as the dedicated support staff are often unfamiliar with problems and troubleshooting, leading to communication gaps that delay issue resolution.
They should also accelerate the process of implementing new features upon request.
I would suggest HP WebInspect as a better option than Tenable.io.
Tenable Vulnerability Management is not very effective for real-time risk prioritization for our organization's security strategy.
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.
We secured a special licensing model for penetration testing companies, which is cost-effective.
The pricing of Acunetix is pretty expensive and could be improved.
Tenable charges around $40 per device, while Rapid7 costs $10 to $15 per device.
I would not say very expensive for Tenable Vulnerability Management; it is not prohibitive, but at the same time, there are some other tools in the marketplace which are offering the same kind of services that Tenable offers, the same kind of features that Tenable has offered at a lesser cost.
Its most valuable role is in enhancing security by identifying potential vulnerabilities efficiently.
The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities.
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.
Tenable enables vulnerability management through potential AI integration that consolidates efforts and resolves multiple vulnerabilities simultaneously.
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.
The best features of Tenable Vulnerability Management are flexibility, breadth and scope, and the fact that their current vulnerabilities come out, and they have tests for them within a day or two.
