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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"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 appreciate the features that Acunetix has for the speed and the fact that it is in the cloud, which does not put any resources in my network, so I can set up a scan, go to bed, come back, and see the reports in my email."
"There is a lot of documentation on their website which makes setting it up and using it quite simple."
"Our developers can run the attacks directly from their environments, desktops."
"Overall, I believe Acunetix to be one of the best products on the market."
"If an organization has 100 plus applications and wants to use an automated scanner, they should definitely go ahead with Acunetix because it is very cost-effective and will save time compared to focusing on other solutions and performing manual security assessments."
"After two years it's about 300%."
"The product provides comprehensive details and reports to help us understand everything and handle any patches in order to keep our system safe."
"It has good unified web application scanning and exposure management."
"We can get detailed information about vulnerabilities."
"I would recommend Tenable.io Web Application Scanning to others."
"Tenable.io Web Application Scanning is very easy to use, provides very reliable results, and is easily managed by someone who lacks prior knowledge, information, or experience."
"Tenable.io Web Application Scanning provides a detailed report, identifying functions that are complex and need to be more maintainable and readable."
"Tenable.io Web Application Scanning is very easy to use."
"If customers need a cost-efficient way to do very good ramification scanning and vulnerability management, this is the right solution."
 

Cons

"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."
"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."
"One of the biggest problems I've had with Acunetix is that it's hard to replicate things manually because you don't get the raw packet."
"The solution is generally stable, however, there might be room for improvement regarding glitches or bugs."
"The pricing is a bit on the higher side."
"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."
"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."
"The reporting has a very limited customization capability."
"It would be great if there were a dashboard that is more user-friendly."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"Tenable.io Web Application Scanning could improve by offering faster fuzzing."
"It isn't easy to manage vulnerabilities in Tenable."
"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."
"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."
"It isn't easy to manage vulnerabilities in Tenable."
 

Pricing and Cost Advice

"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 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."
"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."
"The price is exceptionally high."
"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."
"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."
"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."
"Tenable.io Web Application Scanning is expensive for small businesses."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
