Featured Reviews

KashifJamil - PeerSpot reviewer
Has enabled teams to improve security testing with smooth integration and high accuracy
Acunetix has a very good ratio of fewer false positives, so users don't need to retest everything. Acunetix operates smoothly with no interruptions required, and it performs at 100% efficiency without issues in scanning anything. The solution is excellent at detecting SQL injection and cross-site scripting vulnerabilities. Acunetix integrates with every type of tool, including CI/CD tools, offering 100% integration in DevOps environments. The main benefit of Acunetix is that at the first level, users can address security issues related to penetration testing, allowing them to expose vulnerabilities and ensure all required testing is completed with very few false positives.
Harshal Deshmukh - PeerSpot reviewer
Simple tool to use, good dashboard capabilities and offers asset criticality ratings
It has good dashboard capabilities and gives good results with priority ratings, asset criticality ratings, and exposure scores for vulnerabilities. It also provides automated web application scanning, which customers appreciate because it doesn't disturb the web application or hamper the business. While testing the web application, sometimes it happens that the website or application goes down. But with Tenable.io Web Application Scanning, it doesn't affect the business. It has good unified web application scanning and exposure management.

Quotes from Members

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

Pros

"By integrating with CI/CD tools, it enables a shift-left approach in the development process."
"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."
"It's very user-friendly for the testing teams. It's very easy for them to understand things and to fix vulnerabilities."
"The vulnerability scanning option for analyzing the security loopholes on the websites is the most valuable feature of this solution."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"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."
"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"All the features are valuable to us as they offer cutting-edge scanning methods and address the latest issues with a contemporary approach. Tenable.io Web Application Scanning is highly stable. I rate it a nine out ten. Since the solution works on the Cloud, it's highly scalable. I rate the scalability a nine out of ten. The setup of the solution is straightforward. The Return on Investment is substantial. I recommend the solution to all."
"The most valuable feature is the reporting, which provides a good level of detail with respect to vulnerabilities."
"It is fully automated."
"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."
"Now that the license is centralized, it's a significant feature to manipulate assets based on their functions."
"We use the tool for our websites. We have a vulnerable subdomain. The tool helps to scan it for vulnerabilities."
"The solution is stable."
"We can get detailed information about vulnerabilities."
 

Cons

"Tools that would allow us to work more efficiently with the mobile environment, with Android and iOS."
"There was an issue related to updates from the internet."
"The solution's pricing could be better."
"The pricing is a bit on the higher side."
"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."
"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."
"You can't actually change your password after you've set it unless you go back into the administration account and you change it there. Thus, if you're locked out and don't remember your password, that's a thing."
"When monitoring the traffic we always have issues with the bandwidth consumption and the throttling of traffic."
"The cloud and the on-premises versions have their own controllers, and there is no way to centrally manage controllers."
"The platform's technical support services could be better."
"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."
"Sometimes it lags with different cloud environments."
"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."
"Tenable.io Web Application Scanning conducts a general scan, which wastes time. The scan needs to be specific."
"The technical support should be improved. Currently, some attacks are detected while others are not."
"The dashboard could be more user-friendly."
 

Pricing and Cost Advice

"The price is exceptionally high."
"All things considered, I think it has a good price/value ratio."
"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."
"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 pricing is a little high, and moreover, it's kind of domain-based."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"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."
"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."
"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 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."
