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.

Weekly insights and risk analysis facilitate informed security decisions

I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.

Has enabled teams to improve security testing with smooth integration and high accuracy

Acunetix has a very good ratio of fewer false positives, so users don't need to retest everything. Acunetix operates smoothly with no interruptions required, and it performs at 100% efficiency without issues in scanning anything. The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities. Acunetix integrates with every type of tool, including CI/CD tools, offering 100% integration in DevOps environments. The main benefit of Acunetix is that at the first level, users can address security issues related to penetration testing, allowing them to expose vulnerabilities and ensure all required testing is completed with very few false positives.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We saw benefits from Zafran Security almost immediately after deploying it."

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."

"We are able to see the real risk of a vulnerability on our environment with our security tools."

"Zafran has become an indispensable tool in our cybersecurity arsenal."

"Zafran is an excellent tool."

"I find it to be one of the most comprehensive tools, with support for manual intervention."

"We are able to create a report which shows the PCI DSS scoring and share it with the application teams. Then, they can correlate and see exactly what they need to fix, and why."

"Acunetix has an awesome crawler. It gives a referral site map of near targets and also goes really deep to find all the inputs without issues. This was valuable because it helped me find some files or directories, like web admin panels without authentication, which were hidden."

"There is a lot of documentation on their website which makes setting it up and using it quite simple."

"The most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."

"The automated approach to these repetitive discovery attempts would take days to do manually and therefore it helps reduce the time needed to do an assessment."

"By integrating with CI/CD tools, it enables a shift-left approach in the development process."

"The features of Acunetix have proved most effective in identifying vulnerabilities."

More Acunetix pros

"It is very stable, and it is updated periodically by adding new vulnerabilities."

"Tenable is user-friendly and excels in reporting."

"The stability is commendable, and I would rate Tenable ten out of ten."

"The solution creates vulnerability tickets within the VM profile but should also include them under the Remediation tab so the fixes can be viewed in the ticketing queue."

"Tenable.io, in particular, is quite a powerful product. It looks at your traditional environment, which is pretty much anything that is on-premises, and it also goes a step ahead and covers your modern assets, which is anything that is currently sitting in the cloud. You get complete visibility of your entire environment and tech operation. The ability to give you visibility across the entire tech surface is one of the biggest advantages that Tenable.io has."

"The best feature of the solution is the amount of visibility it provides of the vulnerabilities."

"The initial setup is mostly straightforward."

"It is easy to manage. Most of the information the tool provided helped to further investigate the vulnerability and its impact."

More Tenable Vulnerability Management pros

Cons

"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."

"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."

"The pricing is a bit on the higher side."

"There's a clear need for a reduction in pricing to make the service more accessible."

"Acunetix needs to improve its cost."

"It is difficult to create a proxy connection."

"Currently only supports web scanning."

"We want to see how much bandwidth usage it consumes. When we monitor traffic we have issues with the consumption and throttling of the traffic."

"The vulnerability identification speed should be improved."

"The jargon used makes it difficult for project managers to understand the issues, and the technical explanations used make it difficult for developers to understand issues. These things should be simplified much more. That would be very helpful for us when explaining to them what needs to be fixed. The report output needs to be simplified."

More Acunetix cons

"More flexibility is required compared to other solutions."

"Another area of improvement is customer service and support. Tenable needs to include support in the pricing/license. Currently, they push clients to get support from partners or channel distributors, who often charge a lot."

"I'd like to see them improve their support."

"The interface could be improved; right now it's running on two interfaces simultaneously."

"The initial setup is complex and has room for improvement."

"Users get confused between VPR and CVSS ratings."

"The tool's reports are bad. They're not very customizable or flexible. During audits, we often have to exclude things that aren't relevant to our organization, but we can't do that easily with the reports. They come in HTML or PDF format, and we can't compare current results with previous ones in Excel because we never receive reports in Excel."

"I don't recommend Tenable.io Vulnerability Management for web scanning"

Pricing and Cost Advice

Information not available

"Acunetix was around the same price as all the other vendors we looked at, nothing special."

"The pricing and licensing are reasonable to a point. In order to run multiple scans at a time, we are going to have to purchase a 100 count license, which is an overkill. Though, compared to what we were paying for, the cost seems reasonable."

"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."

"The costs aren't very expensive. It costs around $3000 or $4000."

"The price is exceptionally high."

"The solution is expensive."

"All things considered, I think it has a good price/value ratio."

"Implementing Acunetix needs a medium or larger business agency, because you need some money to get Acunetix. It is costly, but if you care about your agency's security, then maybe it's a cost that might help you in the future."

More Acunetix pricing and cost advice

"Tenable.io Vulnerability Management's pricing solution model isn't great."

"Compared to other VM solutions, Tenable.io Vulnerability Management is expensive."

"Tenable charges around $40 per device."

"On a scale of one to ten, where one is low, and ten is high price, I rate the pricing an eight. So, it is a pretty expensive solution."

"The solution is not too expensive."

"The product costs us around $137,000 annually for 4000 to 5000 assets."

"I would rate the pricing a five out of ten. It is in the middle."

"The tool is reasonably priced."
