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 Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and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

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We use the solution for the scanning of vulnerabilities like SQL injections."
"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."
"Our developers can run the attacks directly from their environments, desktops."
"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."
"Overall, it's a very good tool and a very good engine."
"One of the features that I feel is groundbreaking, that I would like to see expanded on, is the IAS feature: The Interactive Application Security Testing module that gets loaded onto an application on a server, for more in-depth, granular findings. I think that is really neat. I haven't seen a lot of competitors doing that."
"The most valuable feature of the solution is the speed at which it can scan multiple domains in just a few hours."
"The solution is highly stable."
"Tenable.io Web Application Scanning is very easy to use."
"Our customers adopt this solution because of the replication testing and the vulnerability assessment it can do. It is a multi-faceted product."
"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."
"I would recommend Tenable.io Web Application Scanning to others."
"We can get detailed information about vulnerabilities."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"It is fully automated."
"The most effective feature of the product is the ability to scan the entire environment."
 

Cons

"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."
"Integration into other tools is very limited for Acunetix. While we're trying to incorporate a CI/CD process where we're integrating with JIRA and we're integrating with Jenkins and Chef, it becomes problematic. Other tools give you a high integration capability to connect into different solutions that you may already have, like JIRA."
"Acunetix needs to improve its cost."
"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."
"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."
"There is room for improvement in website authentication because I've seen other products that can do it much better."
"It is difficult to create a proxy connection."
"Acunetix may need to reconsider the cost or price compared to other vendors."
"The solution's dashboards could be improved and made more user-friendly."
"The market is standard for vulnerability scanning, however, the posture can be improved through Tenable's prioritization engine."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"Sometimes it lags with different cloud environments."
"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."
"The dashboard could be more user-friendly."
"The reporting has a very limited customization capability."
"The platform's technical support services could be better."
 

Pricing and Cost Advice

"The pricing is a little high, and moreover, it's kind of domain-based."
"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 price is exceptionally high."
"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 costs aren't very expensive. It costs around $3000 or $4000."
"All things considered, I think it has a good price/value ratio."
"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."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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 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."
"I rate the product's pricing a four out of ten."
"Tenable.io Web Application Scanning is expensive for small businesses."
"For Tenable.io Web Application Scanning, it comes to around 6,50,000 Indian rupees, plus taxes."
"It follows the same licensing scheme as Tenable.io and Tenable. sc."
"The pricing is okay."
