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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

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

"Segregation of reports is really, really good with Acunetix; it provides us with a lot of in-depth details."
"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 scalability is more than good; it can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have, and this solution is simple enough, especially with the cloud."
"The vulnerability scanning option for analyzing the security loopholes on the websites is the most valuable feature of this solution."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."
"It has been able to find some vulnerabilities, and we've been able to remediate our websites and vulnerabilities, thanks to Acunetix."
"One of the features that I feel is groundbreaking, that I would like to see expanded on, is the IAS feature: The Interactive Application Security Testing module that gets loaded onto an application on a server, for more in-depth, granular findings. I think that is really neat. I haven't seen a lot of competitors doing that."
"The product provides comprehensive details and reports to help us understand everything and handle any patches in order to keep our system safe."
"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."
"I think Tenable.io Web Application Scanning is the best option on the market at the moment."
"I would recommend Tenable.io Web Application Scanning to others."
"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
 

Cons

"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."
"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."
"The Acunetix licensing and pricing model is somewhat complicated. If we calculated all of our domains and sub-domains, the sum would be huge; that's why we thought of leaving Acunetix."
"There was an issue related to updates from the internet."
"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."
"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."
"There are quite a few false positives that come out. It's mostly based upon finding XSS vulnerabilities, even though we know that XSS vulnerabilities do not exist within some of the web applications because of some frameworks we're using."
"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."
"Sometimes it lags with different cloud environments."
"The report customization needs to be better."
"It isn't easy to manage vulnerabilities in Tenable."
"The reporting has a very limited customization capability."
"The dashboard could be more user-friendly."
"We have encountered some problems with the technical support from Tenable; I would rate it a five out of ten. It is not efficacious, especially the first-level support."
"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."
 

Pricing and Cost Advice

"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."
"All things considered, I think it has a good price/value ratio."
"The pricing is a little high, and moreover, it's kind of domain-based."
"The solution is expensive."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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."
"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 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."
"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."
"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."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
