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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"Overall, it's a very good tool and a very good engine."
"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."
"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."
"The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"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."
"By integrating with CI/CD tools, it enables a shift-left approach in the development process."
"It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
"It collects the vulnerabilities on the hostnames and sends them to the Tenable.io cloud. Tenable has its own cloud where Tenable.io is running, but there are many connectors to other cloud solutions. Tenable can do vulnerability scanning for other cloud managers such as Azure, Amazon, and so on."
"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."
"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."
"It is fully automated."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
 

Cons

"There is room for improvement in website authentication because I've seen other products that can do it much better."
"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."
"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."
"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."
"I rate its stability six out of ten."
"There are some versions of the solution that are not as stable as others."
"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."
"There is room for improvement in the pricing."
"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."
"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 could improve by offering faster fuzzing."
"It isn't easy to manage vulnerabilities in Tenable."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"The solution's dashboards could be improved and made more user-friendly."
"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."
 

Pricing and Cost Advice

"The pricing is a little high, and moreover, it's kind of domain-based."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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."
"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 costs aren't very expensive. It costs around $3000 or $4000."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"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 solution is expensive."
"The pricing is okay."
"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."
"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."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"I rate the product's pricing a four out of ten."
