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.
Amit Beniwal - PeerSpot reviewer
Simplifies vulnerability discovery and has high quality support
There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores. Sometimes, a vulnerability initially categorized as high severity may be reduced to medium or low over time after security patches are applied. This alignment with the present severity score and CVSS score could be improved.

Quotes from Members

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

Pros

"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 most important feature is that it's a web-based graphical user interface. That is a great addition. Also, the ability to schedule scans is great."
"The tool's most valuable feature is scan configurations. We use it for external physical applications. The scanning time depends on the application's code."
"We use the solution for the scanning of vulnerabilities like SQL injections."
"I find it to be one of the most comprehensive tools, with support for manual intervention."
"The tool's most valuable feature is performance."
"Their technical support has been very active. If I have an issue, I can reach out to them and get an answer pretty quick."
"The product is really easy to use."
"The solution is good at reporting the vulnerabilities of the application."
"They offer free access to some other tools."
"OWASP is quite matured in identifying the vulnerabilities."
"It can be used effectively for internal auditing."
"Two features are valuable. The first one is that the scan gets completed really quickly, and the second one is that even though it searches in a limited scope, what it does in that limited scope is very good. When you use Zap for testing, you're only using it for specific aspects or you're only looking for certain things. It works very well in that limited scope."
"The solution is scalable."
"The application scanning feature is the most valuable feature."
"The stability of the solution is very good."
 

Cons

"Acunetix needs to improve its cost."
"The cost can be reduced as management has noted it to be on the higher side."
"The solution is generally stable, however, there might be room for improvement regarding glitches or bugs."
"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."
"We have had issues during upgrades where their scans worked on some apps better with previous versions. Then, we had to work with their tech support, who were great, to get it fixed for the next version."
"There is room for improvement in the pricing."
"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."
"The vulnerability identification speed should be improved."
"OWASP Zap needs to extend to mobile application testing."
"There isn't too much information about it online."
"The automated vulnerability assessments that the application performs needs to be simplified as well as diversified."
"The documentation needs to be improved because I had to learn everything from watching YouTube videos."
"Deployment is somewhat complicated."
"OWASP should work on reducing false positives by using AI and ML algorithms."
"It would be a great improvement if they could include a marketplace to add extra features to the tool."
"The documentation is lacking and out-of-date, it really needs more love."
 

Pricing and Cost Advice

"The price is exceptionally high."
"The solution is expensive."
"The cost is based on two types of licenses, ConsultLite, and ConsultPlus, as well as the number of domains that are scanned."
"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 costs aren't very expensive. It costs around $3000 or $4000."
"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."
"I would say that Acunetix is expensive because there are products on the market with similar features that are equally or better-priced."
"Acunetix was around the same price as all the other vendors we looked at, nothing special."
"This is an open-source solution and can be used free of charge."
"The solution’s pricing is high."
"It is open source, and we can scan freely."
"This app is completely free and open source. So there is no question about any pricing."
"It's free. It's good for us because we don't know what the extent of our use will be yet. It's good to start with something free and easy to use."
"It is highly recommended as it is an open source tool."
"The tool is open-source."
"It's free and open, currently under the Apache 2 license. If ZAP does what you need it to do, selling a free solution is a very easy."
