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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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.

Centralized license management transforms asset manipulation based on functions and improves security posture
Now that the license is centralized, it's a significant feature to manipulate assets based on their functions. It provides a centralized view from end-to-end to its assets' identities and vulnerabilities. One of the greatest features is Kubernetes. The automated scanning capability is pretty standard in the market, and Tenable's prioritization engine helps improve the security posture.

Pros

"Picks up weaknesses in our app setups."
"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."
"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"I haven't seen reporting of that level in any other tool."
"By helping me patch vulnerabilities, Acunetix has led to measurable outcomes like time saved and fewer incidents."
"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."
"The most valuable feature of Acunetix is the UI and the scan results are simple."
"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."
"The most effective feature of the product is the ability to scan the entire environment."
"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."
"Tenable.io Web Application Scanning is very easy to use."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"I would recommend Tenable.io Web Application Scanning to others."
 

Cons

"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."
"Acunetix may need to reconsider the cost or price compared to other vendors."
"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."
"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."
"Acunetix should improve by further reducing false positives and providing more customized reports, plus better integration with newer tools such as GitHub and Azure DevOps."
"There is room for improvement in the pricing."
"The pricing is a bit on the higher side."
"The cost can be reduced as management has noted it to be on the higher side."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"They have a general dashboard for web application scanning, but the dashboards and reporting can be improved. They probably have some features in their roadmap."
"I would like for them to add proxy filtering, where you can transfer and alter the package. It is fully automated. Other web application testers programs are actually proxy software, and the proxy software gives you the flexibility of modifying the outgoing package, which will actually help you in exploiting any vulnerability in detail."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"Tenable.io Web Application Scanning is not very user-friendly and you need a lot of information to get proper reports. The tool's support is not very responsive."
"The solution's dashboards could be improved and made more user-friendly."
"It isn't easy to manage vulnerabilities in Tenable."
 

Pricing and Cost Advice

"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"The price is exceptionally high."
"All things considered, I think it has a good price/value ratio."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"When compared with other products, the pricing is a little bit high. But it gives value for the price. It serves the purpose and is worthwhile for the price we pay."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"The solution is expensive."
"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 pricing is okay."
"I rate the product's pricing a four out of ten."
"Tenable.io Web Application Scanning is expensive for small businesses."
"The price of the solution is reasonable compared to the competitors. The license cost is based on the number of users and the annual usage."
"The application is extremely affordable. There are no additional costs involved with licensing. We switched to Tenable.io Web Application Scanning from other solutions due to pricing."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
