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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

Quotes from Members

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

Pros

"Since implementing Acunetix, I have seen improvements as we have discovered real vulnerabilities and threats on our web application server, which is very critical to our organization."

"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 most valuable feature of Acunetix is the UI and the scan results are simple."

"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."

"We are able to create a report which shows the PCI DSS scoring and share it with the application teams. Then, they can correlate and see exactly what they need to fix, and why."

"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."

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

"The tool's most valuable feature is performance."

More Acunetix pros

"I think Tenable.io Web Application Scanning is the best option on the market at the moment."

"Tenable.io Web Application Scanning is very easy to use."

"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."

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

"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."

"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."

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

"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."

More Tenable.io Web Application Scanning pros

Cons

"Improving the handling of false positives would be beneficial because it can be challenging to trust the findings flagged by Acunetix, and those findings must be manually validated."

"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."

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

"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."

"Acunetix may need to reconsider the cost or price compared to other vendors."

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

"The vulnerability identification speed should be improved."

"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."

More Acunetix cons

"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."

"The technical support should be improved. Currently, some attacks are detected while others are not."

"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."

"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 conducts a general scan, which wastes time. The scan needs to be specific."

"Sometimes it lags with different cloud environments."

"The technical support needs improvement. Currently, it takes time, which might be due to the free version, but providing some level of support could encourage future purchase decisions."

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

More Tenable.io Web Application Scanning cons

Pricing and Cost Advice

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

"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."

"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."

"Implementing Acunetix needs a medium or larger business agency, because you need some money to get Acunetix. It is costly, but if you care about your agency's security, then maybe it's a cost that might help you in the future."

"The costs aren't very expensive. It costs around $3000 or $4000."

"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."

"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."

"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."

More Acunetix pricing and cost advice

"It follows the same licensing scheme as Tenable.io and Tenable. sc."

"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 pricing is okay."

"I rate the product's pricing a four out of ten."

"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."
