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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"The most valuable feature of Acunetix is the UI and the scan results are simple."
"Our developers can run the attacks directly from their environments, desktops."
"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."
"There is a lot of documentation on their website which makes setting it up and using it quite simple."
"It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."
"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."
"The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities."
"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."
"I think Tenable.io Web Application Scanning is the best option on the market at the moment."
"It is fully automated."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"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 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."
"The solution's instant reports feature is the most effective for detecting threats."
"I would recommend Tenable.io Web Application Scanning to others."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
 

Cons

"I rate its stability six out of ten."
"Acunetix needs to improve its cost."
"Acunetix needs to be dynamic with JavaScript code, unlike Netsparker which can scan complex agents."
"The solution can be improved by adding the ability to scan subdomains automatically, and by providing reports that can be exported to external databases to share with other solutions."
"The solution is generally stable, however, there might be room for improvement regarding glitches or bugs."
"There are some versions of the solution that are not as stable as others."
"The cost can be reduced as management has noted it to be on the higher side."
"Acunetix may need to reconsider the cost or price compared to other vendors."
"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 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."
"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."
"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 report customization needs to be better."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"It isn't easy to manage vulnerabilities in Tenable."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
 

Pricing and Cost Advice

"The solution is expensive."
"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."
"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 cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"All things considered, I think it has a good price/value ratio."
"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."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"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."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"Tenable.io Web Application Scanning is expensive for small businesses."
"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."
"The pricing is okay."
"I rate the product's pricing a four out of ten."
