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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"It comes equipped with an internal applicator, which automatically identifies and addresses vulnerabilities within the program."
"The usability and overall scan results are good."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"There is a lot of documentation on their website which makes setting it up and using it quite simple."
"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."
"It can operate both as a standalone and it can be integrated with other applications, which makes it a very versatile solution to have."
"The scalability is good. The scalability is more than good because it can operate both as a standalone and it can be integrated as part of applications. So that really makes it a very, very versatile solution to have."
"Overall, it's a very good tool and a very good engine."
"I think Tenable.io Web Application Scanning is the best option on the market at the moment."
"The most effective feature of the product is the ability to scan the entire environment."
"We can get detailed information about vulnerabilities."
"The solution's instant reports feature is the most effective for detecting threats."
"I would recommend Tenable.io Web Application Scanning to others."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"It has good unified web application scanning and exposure management."
"The initial setup is straightforward."
 

Cons

"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."
"The only problem that they have is the price. It is a bit expensive, and you cannot change the number of applications for the whole year."
"Acunetix needs to improve its cost."
"The cost can be reduced as management has noted it to be on the higher side."
"While we do have it integrated with other solutions, it could still offer more integrations."
"I think Acunetix needs improvement since it is now working with Invicti, so the price list will need to be reconsidered."
"There is room for improvement in the pricing."
"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."
"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."
"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."
"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 solution's dashboards could be improved and made more user-friendly."
"The platform's technical support services could be better."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
 

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."
"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 is a little high, and moreover, it's kind of domain-based."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"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."
"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."
"The costs aren't very expensive. It costs around $3000 or $4000."
"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."
"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."
"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."
"I rate the product's pricing a four out of ten."
