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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

Provides detailed reports that improve code maintainability while needing better coverage reports and technical support
Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable. It offers features such as generating an executive summary and detailed reports highlighting issues in specific lines of the code. However, it does not provide coverage reports in the free version, which is a limitation.

Quotes from Members

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

Pros

"We use the solution for the scanning of vulnerabilities like SQL injections."
"I appreciate the features that Acunetix has for the speed and the fact that it is in the cloud, which does not put any resources in my network, so I can set up a scan, go to bed, come back, and see the reports in my email."
"The usability and overall scan results are good."
"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."
"The tool's most valuable feature is performance."
"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."
"Our developers can run the attacks directly from their environments, desktops."
"Acunetix is the best service in the world. It is easy to manage. It gives a lot of information to the users to see and identify problems in their site or applications. It works very well."
"It is fully automated."
"The solution's instant reports feature is the most effective for detecting threats."
"The initial setup is straightforward."
"It has good unified web application scanning and exposure management."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"All the features are valuable to us as they offer cutting-edge scanning methods and address the latest issues with a contemporary approach. Tenable.io Web Application Scanning is highly stable. I rate it a nine out ten. Since the solution works on the Cloud, it's highly scalable. I rate the scalability a nine out of ten. The setup of the solution is straightforward. The Return on Investment is substantial. I recommend the solution to all."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"We can get detailed information about vulnerabilities."
 

Cons

"I rate its stability six out of ten."
"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."
"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."
"Acunetix needs to include agent analysis."
"Currently only supports web scanning."
"The pricing is a bit on the higher side."
"There is room for improvement in website authentication because I've seen other products that can do it much better."
"In terms of what needs improvement, the way the licensing model is currently is not very convenient for us because initially, when we bought it, the licensing model was very flexible, but now it restricts us."
"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 could improve by offering faster fuzzing."
"The platform's technical support services could be better."
"The dashboard could be more user-friendly."
"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."
"The reporting has a very limited customization capability."
"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."
 

Pricing and Cost Advice

"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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."
"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 price is exceptionally high."
"The pricing is a little high, and moreover, it's kind of domain-based."
"The costs aren't very expensive. It costs around $3000 or $4000."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"The solution is expensive."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"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."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"Tenable.io Web Application Scanning is expensive for small businesses."
"The pricing is okay."
"I rate the product's pricing a four out of ten."
"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."
