Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"I haven't seen reporting of that level in any other tool.""The usability and overall scan results are good.""The most valuable feature of Acunetix is the UI and the scan results are simple.""Picks up weaknesses in our app setups.""There is a lot of documentation on their website which makes setting it up and using it quite simple.""Overall, it's a very good tool and a very good engine.""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.""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."

"Tenable Nessus is one of the best vulnerability assessment tools, that I know.""With the Tenable Nessus enterprise edition, you have unlimited licenses to scan the device.""I have found the vulnerability assessment and the reports to be useful.""Tenable Nessus is cheap and flexible.""Out of the box, the product works well for us, so it's not a tool that we need to customize very much.""User friendly and good dashboards.""It is easy to deploy and easy to use. Its reporting is good. From this reporting, you can see the pain point in your network, which makes it easy to fix them. It is easy to understand the reports and export them.""Ease of reviewing scores, identifying vulnerabilities, and getting information on them."

More Tenable Nessus Pros →

"While we do have it integrated with other solutions, it could still offer more integrations.""There is room for improvement in website authentication because I've seen other products that can do it much better.""The pricing is a bit on the higher side.""Currently only supports web scanning.""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 jargon used makes it difficult for project managers to understand the issues, and the technical explanations used make it difficult for developers to understand issues. These things should be simplified much more. That would be very helpful for us when explaining to them what needs to be fixed. The report output needs to be simplified.""The vulnerability identification speed should be improved.""There are some versions of the solution that are not as stable as others."

More Acunetix Cons →

"In terms of what could be improved, I would say its reporting portion.""We'd like to see more integration potential within the solution.""The reporting is a bit cumbersome.""The solution could improve by having better integration with different vendors' IPS solutions. The ACLs and IPS policies signatures should be enabled based on the results of Tenable Nessus automatically, we currently have to do it manually which is very time-consuming. It has done a good job integrating with Fortinet but we would like it to be better integrated with other solutions that we have.""Tenable Nessus is not feasible for a large company.""Tenable Nessus application device assessment is one of the top tools. However, in the application security assessment, there are other tools that provide better, and more accurate findings.""The inventory management function in this solution needs improvement.""The report for counters is too simple and would be improved by a dashboard."

Pricing and Cost Advice
  • "I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
  • "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."
  • "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."
  • "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."

  • "Nowadays, your vulnerability applications are going to be kind of pricey because lots of them, including Rapid7, are based upon a base price, but then they add in the nodes. That's where they get you. If you're a big network, obviously, you need to scan everything. Therefore, it's going to be costly. The risk and insurance money associated with having ransomware on my networks is going to cost me more money, time, and marketing than the price of the tool. That's why I'm speaking only as an information security officer to security operations. This is the tool that is there in my toolbox to say whether we vulnerable or not. At this point, I don't care about how much it costs my company to have it because if I wasn't able to report it and we got ransomware, then who cares? I'm probably going to be out of business because it happened. That's why I don't care about the price. I have it, and I could use it effectively and do my report. At the end of the day, even if we get ransomware, as long as I reported it, followed my protocol, and put in the change, irrespective of whether it was ignored or denied, I did my job."
  • "We pay approximately $2,500 on a yearly basis."
  • "We have a subscription, the licensing fees are paid yearly, and I am using the latest version."
  • "We incurred a single cost for a perpetual license, although I cannot comment on the price as this is above my management level."
  • "The price is reasonable."
  • "In general, it is extremely expensive."
  • "The price of the solution is reasonable."
  • "One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
