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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"The product is really easy to use."

"It generates automated reports."

"We are happy, we're not unhappy with Acunetix, but we are very impressed by some of the things that it has been doing."

"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 solution is paying for itself, as our applications are more secure."

"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."

"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."

"There is a lot of documentation on their website which makes setting it up and using it quite simple."

More Acunetix pros

"The most effective feature of the product is the ability to scan the entire environment."

"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."

"The solution's instant reports feature is the most effective for detecting threats."

"If customers need a cost-efficient way to do very good ramification scanning and vulnerability management, this is the right solution."

"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."

"The solution is stable."

"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."

"I would recommend Tenable.io Web Application Scanning to others."

Cons

"The cost can be reduced as management has noted it to be on the higher side."

"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."

"Currently only supports web scanning."

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

"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."

"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."

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

More Acunetix cons

"Tenable.io Web Application Scanning could improve by offering faster fuzzing."

"It would be great if there were a dashboard that is more user-friendly."

"The reporting has a very limited customization capability."

"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."

"It isn't easy to manage vulnerabilities in Tenable."

"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 reporting in Tenable.io Web Application Scanning is not as good as the reporting in Tenable SC."

"The dashboard could be more user-friendly."

More Tenable.io Web Application Scanning cons

Pricing and Cost Advice

"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."

"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."

"The pricing is a little high, and moreover, it's kind of domain-based."

"The price is exceptionally high."

"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."

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

More Acunetix pricing and cost advice

"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 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."

"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."

"Tenable.io Web Application Scanning is expensive for small businesses."
