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.

Streamlines vulnerability management with excellent reporting and potential AI integration

Tenable is user-friendly and excels in reporting. It allows me to easily fetch and schedule reports. The software's discovery feature aids in strengthening our security posture. The single-sensor installation process on various operating systems is smooth, unlike Rapid7, which requires different versions for separate systems. Furthermore, Tenable enables vulnerability management through potential AI integration that consolidates efforts and resolves multiple vulnerabilities simultaneously.

Quotes from Members

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

Pros

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

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

"Zafran is an excellent tool."

"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."

"Overall, it's a very good tool and a very good engine."

"The most important feature is that it's a web-based graphical user interface. That is a great addition. Also, the ability to schedule scans is great."

"It generates automated reports."

"Picks up weaknesses in our app setups."

"The scalability is good. The scalability is more than good because it can operate both as a standalone and it can be integrated as part of applications. So that really makes it a very, very versatile solution to have."

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

"The usability and overall scan results are good."

"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."

More Acunetix pros

"Tenable.io Vulnerability Management is an easy-to-use product. I"

"It is a very, very user-friendly tool...The setup is easy"

"It is a stable solution. Stability-wise, I rate the solution a ten out of ten."

"The integration of Tenable into our security ecosystem was very good."

"The ease of use in terms of scanning assets is valuable."

"It is quite straightforward to set up."

"It is pretty stable. I would rate it nine or maybe ten."

"A new user can easily understand the workflow, even if they are creating users for other divisions and the user is a beginner."

More Tenable Vulnerability Management pros

Cons

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

"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."

"Currently only supports web scanning."

"The solution limits the number of scans. It would be much better if we could have unlimited scans."

"We have had issues during upgrades where their scans worked on some apps better with previous versions. Then, we had to work with their tech support, who were great, to get it fixed for the next version."

"There are some versions of the solution that are not as stable as others."

"It is difficult to create a proxy connection."

"Integration into other tools is very limited for Acunetix. While we're trying to incorporate a CI/CD process where we're integrating with JIRA and we're integrating with Jenkins and Chef, it becomes problematic. Other tools give you a high integration capability to connect into different solutions that you may already have, like JIRA."

"The solution's pricing could be better."

"You can't actually change your password after you've set it unless you go back into the administration account and you change it there. Thus, if you're locked out and don't remember your password, that's a thing."

More Acunetix cons

"The shortcoming of the solution that needs improvement is related to its capability to do vulnerability assessments on applications."

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

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

"I'm not satisfied with the reporting structure."

"The pricing of the solution could be more reasonable."

"We'd like to see a bit more user-friendliness."

"Tenable.io Vulnerability Management could be improved with an increased number of dashboards and MSSP integration."

"The only drawback of the solution is that it is expensive."

Pricing and Cost Advice

Information not available

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

"When we looked at all other vendors and what they were asking for, to provide a third of what Acunetix was capable of doing, it was an easy decision... But now that it's coming to a cost where it's line with market value, it becomes more of a competition... Acunetix is raising the cost of licensing. It's 3.5 times what we were initially quoted."

"The solution is expensive."

"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."

"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."

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

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

"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."

More Acunetix pricing and cost advice

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

"Tenable.io is not known for being a cheap product."

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

"Yearly payments are to be made toward the licensing cost of the product. It is neither a cheap nor an expensive product."

"Tenable charges around $40 per device."

"The tool is reasonably priced."

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

"The solution is not too expensive."
