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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

Security Analyst at TOPNET
Web audits have identified vulnerabilities and now provide clear visibility into compliance gaps
We have experience with Tenable.io Web Application Scanning, and we use it as well; we have approximately ten licenses for web application scanning. We use it to find vulnerabilities, but Tenable.io Web Application Scanning does not include remediation; we remediate with other products. We use the…

Quotes from Members

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

Pros

"The most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."
"We are happy, we're not unhappy with Acunetix, but we are very impressed by some of the things that it has been doing."
"It generates automated reports."
"Acunetix helps reduce the man-days and effort needed for scanning bulk applications through automated assessments, allowing good dashboard visualization that can be reported easily to management, providing complete visibility on vulnerability metrics."
"The solution is comprehensive and easy to use."
"The most important element for us is that it's very easy for developers to use, as they don't need to have any knowledge about security or threats; they just run the tool against their application and get the results."
"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."
"Login Sequence Recorder, scan throttling, and fantastic reporting output are the most valuable features."
"It collects the vulnerabilities on the hostnames and sends them to the Tenable.io cloud, and there are many connectors to other cloud solutions so Tenable can do vulnerability scanning for other cloud managers such as Azure and Amazon."
"The most valuable features of Tenable.io Web Application Scanning are the integration into specific use cases and scanning. All of the features of the solution are useful."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"Tenable.io Web Application Scanning is very easy to use, provides very reliable results, and is easily managed by someone who lacks prior knowledge, information, or experience."
"I would recommend Tenable.io Web Application Scanning to others."
"Our primary use case for the solution is automated scanning; it doesn't require scripting knowledge or any of those suites or other tools, so it is fully automated, and we provide the credentials and URL and the tool does all scanning and will show the result per the requirement."
"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."
 

Cons

"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."
"However, it doesn't seem very helpful or useful for scanning web services, and that has what I feel that the organization could work better on that."
"I had some issues with the JSON parameters where it found some strange vulnerabilities, but it didn't alert the person using it or me about these vulnerabilities, e.g., an error for SQL injection."
"Acunetix needs to improve its cost."
"The cost can be reduced as management has noted it to be on the higher side."
"It would be nice to have a feature to "retest" only a single vulnerability that the customer reports as patched, and delete it from the next scans since it has already been patched."
"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."
"There is room for improvement in the pricing."
"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."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"The platform's technical support services could be better."
"I would like for them to add intervening proxy, whereby you can alter the get/put requests."
"The report customization needs to be better."
"The dashboard could be more user-friendly."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
 

Pricing and Cost Advice

"The price is exceptionally high."
"It is a bit expensive. If you need to check five applications, you have to pay almost 14,000. It is an agreement for two years at 7,000 per year for only five applications. You cannot change the applications in the license. So, you are stuck with the same license for the five applications for one full year."
"The solution is expensive."
"All things considered, I think it has a good price/value ratio."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"The pricing is a little high, and moreover, it's kind of domain-based."
"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."
"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."
"The pricing is okay."
"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."
"Tenable.io Web Application Scanning is expensive for small businesses."
"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."
