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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"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."
"I haven't seen reporting of that level in any other tool."
"Our developers can run the attacks directly from their environments, desktops."
"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 usability and overall scan results are good."
"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."
"It's a very easy deployment and easy application."
"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."
"If customers need a cost-efficient way to do very good ramification scanning and vulnerability management, this is the right solution."
"It has good unified web application scanning and exposure management."
"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."
"The initial setup is straightforward."
"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 is stable."
"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."
"Tenable provides the end analysis results covering all the published vulnerabilities and information on the market."
 

Cons

"We have had issues/hiccups during upgrades where their scans worked on some apps better with previous versions."
"While we do have it integrated with other solutions, it could still offer more integrations."
"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."
"I rate its stability six out of ten."
"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."
"There's a clear need for a reduction in pricing to make the service more accessible."
"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 great if there were a dashboard that is more user-friendly."
"The dashboard could be more user-friendly."
"The report customization needs to be better."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"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 market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."
"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 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."
"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."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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."
"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."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"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."
"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."
"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."
