Vivek Ashvinbhai Pancholi - PeerSpot reviewer
Commendable Solution with Robust Vulnerability Detection Mechanism Suitable for Global Market
The solution helped us with one of our clients in the New York area contacted us about a data breach. In response, we swiftly organized a case meeting involving our client, internal, and email customer support teams. Together, we conducted an incident response, facilitating offline assistance for proper planning and risk management processes. We delved into the details of the data breach, identified how it occurred, and collaborated to rectify the issue. The client expressed satisfaction with the resolution process.
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

"I like the fully automated continuous discovery run by ImmuniWeb in the background. We do not need to rerun the same tests or the same scanning against our resources. We need to supply our IP addresses, domain names, and significant resources with special domain names and URLs, and we need to do it only once. Then we always have an up-to-date picture. I also like the integration with our single sign-on system. We do not need to maintain a separate set of usernames or user accounts. We can plug this ImmuniWeb service into our authentication technology, enabling two-factor authentication. We have secure authentication right out of the box. The other important feature I like is the executive view. You can easily switch from a technical view to an executive view and have a helicopter view of the compliance status. We can see how much effort is required and our current status."
"ImmuniWeb boasts a robust vulnerability detection mechanism, formidable threat mitigation, and an efficient remediation process, incorporating automation techniques and ALM strategies. The solution is highly stable. The solution is scalable. Editing Key Points for Review "Review about ImmuniWeb" What is our primary use case? We use the solution when we face challenges and urgent attention is needed for complex cases from our clients. To address this, we collaborate with the middleware, internal, and client teams to analyze and sort through intricate logs concerning our business cybersecurity program. How has it helped my organization? The solution helped us with one of our clients in the New York area contacted us about a data breach. In response, we swiftly organized a case meeting involving our client, internal, and email customer support teams. Together, we conducted an incident response, facilitating offline assistance for proper planning and risk management processes. We delved into the details of the data breach, identified how it occurred, and collaborated to rectify the issue. The client expressed satisfaction with the resolution process. What is most valuable? ImmuniWeb boasts a robust vulnerability detection mechanism, formidable threat mitigation, and an efficient remediation process, incorporating automation techniques and ALM strategies. It also focuses on consumer satisfaction and operates in English-speaking markets, primarily required by the UAE, the United States, Canada, and Australia, among other developed countries. For how long have I used the solution? We have been using this product for the past one and half years. What do I think about the stability of the solution? The solution is highly stable. I rate it a perfect ten. What do I think about the scalability of the solution? The solution is scalable. I rate it a nine out of ten. How are customer service and support? Support is generally excellent"
"The solution's most valuable feature is reporting."
"The most valuable features are the SLA of Zero false-positives, less time of service development, validation of unlimited patched vulnerabilities, and several others."
"After the assessment, you clearly know which assets require penetration testing."
"ImmuniWeb is stable."
"The initial setup process is user-friendly."
"The solution is good at reporting the vulnerabilities of the application."
"The ZAP scan and code crawler are valuable features."
"The solution is scalable."
"I consider OWASP Zap to be the most effective solution overall; being open source allows integration with other systems via OWASP Zap APIs."
"OWASP is quite matured in identifying the vulnerabilities."
"The stability of the solution is very good."
"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool."
"The API is exceptional."
 

Cons

"It would be better if they had an automated tagging feature. The tagging functionality currently requires manual tagging, and that's probably the most needed feature from my standpoint. We also do not have enough tools, enough features, or options to display different resources in the way we need. There are basic grouping and some filtering features, but we still cannot fully separate some flavors of our resources. However, we may not be aware of the latest features."
"A great idea would be to support using Discovery on the internal network, allowing delivery of all the features of the current Discovery to internal network resources."
"A great idea would be to make a mobile application for the ImmuniWeb portal so that all information would be available on the go and from a mobile phone as well. It would be much more convenient."
"The deployment process on the cloud is straightforward, while on-premise can be complex. Support is generally excellent, although there can be delays in ticket resolution."
"The product’s interface for the web applications could be similar to Android and iOS versions."
"Its technical support could be better."
"ImmuniWeb sometimes shows previous scans instead of running tests."
"The reporting feature could be more descriptive."
"I'd like to see a kind of feature where we can just track what our last vulnerability was and how it has improved or not. More reports that can have some kind of base-lining, I think that would be a good feature too. I'm not sure whether it can be achieved and implement but I think that would really help."
"Zap could improve by providing better reports for security and recommendations for the vulnerabilities."
"There are areas for improvement with OWASP Zap, particularly in the alignment of vulnerabilities concerning CVSS scores."
"The product should allow users to customize the report based on their needs."
"OWASP should work on reducing false positives by using AI and ML algorithms. They should expand their capabilities for broader coverage of business logic flaws and complex issues."
"The solution is somewhat unreliable because after we get the finding, we have to manually verify each of its findings to see whether it's a false positive or a true finding, and it takes time."
"The technical support team must be proactive."
 

Pricing and Cost Advice

"The values of ImmuniWeb are currently significantly below what is valued in the Chilean market for these services and solutions."
"There should be the flexibility to change or add pricing, especially for pay-per-use cases."
"I use the product's free version. The tool costs around 229 dollars."
"It is pretty expensive."
"The platform is expensive if a large development is involved. However, it is less expensive for scheduled-based testing, quarterly or in a year."
"It is pretty expensive."

"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 is highly recommended as it is an open source tool."
"The tool is open source."
"OWASP ZAP is a free tool provided by OWASP’s engineers and experts. There is an option to donate."
"This solution is open source and free."

"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."
