Executive SummaryUpdated on Oct 8, 2024

ImmuniWeb and OWASP Zap are leading tools in the cybersecurity space. ImmuniWeb appears to have the edge due to better support and easier deployment, despite OWASP Zap's extensive features making it a feature-rich option.

Features: ImmuniWeb users value its AI-driven vulnerability scanner, intuitive threat detection processes, and ease of use. OWASP Zap users highlight its robust penetration testing capabilities, extensive integrations, and focus on advanced testing features suitable for experts.

Room for Improvement: ImmuniWeb users suggest enhancements in reporting features, reduction in false positives, and increased detail in vulnerability reports. OWASP Zap requires improvements in its learning curve, more detailed documentation, and simplification of setup for beginners.

Ease of Deployment and Customer Service: ImmuniWeb is known for simple deployment and a responsive support team, facilitating quick implementation. OWASP Zap, while comprehensive in support, needs more setup time, potentially delaying deployment for new users.

OWASP Zap's open-source nature offers cost-free access but might incur hidden costs due to the need for skilled handling.

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.

Open source testing tool empowers manual activities and has room to improve integration and reporting features

The improvement that has to be done for APIs focuses on manual activities where the feature exists, but it is not at the same level as what Burp Suite does with intercepting and tools such as Postman, so it needs improvement. There are limitations with authentication levels, particularly with form-based and cookie-based authentication. However, overall, we are satisfied with OWASP Zap as there are no major issues, and improving the scan engine could be beneficial. When comparing OWASP Zap and Burp Suite, the main difference besides pricing is that OWASP Zap has limitations with reporting levels and UI, which affects its reporting capabilities, whereas Burp Suite is already advancing with new AI features and scanning capabilities that OWASP Zap seems to be lacking.

Quotes from Members

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

Pros

"The initial setup process is user-friendly."

"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."

"The solution's most valuable feature is reporting."

"The ImmuniWeb Platform is the best and easiest way to secure a business online."

"After the assessment, you clearly know which assets require penetration testing."

"ImmuniWeb is stable."

"I have managed to deliver to my clients the services of Ethical Hacking in less time, with better deliverables, and other key differentiators that make my company more competitive in the local market."

"The most valuable features are the SLA of Zero false-positives, less time of service development, validation of unlimited patched vulnerabilities, and several others."

More ImmuniWeb pros

"If you're a company and you've got your own websites, internally and externally, it's great."

"The solution enables a person to add the certificate and check the queries, to see if there are any that are undefined, so a person can have a list of the types of queries and can trace them."

"The OWASP's tool is free of cost, which gives it a great advantage, especially for smaller companies to make use of the tool and at the same time give a comprehensive report with great confidence to the client for helping them in their go-live decision."

"The valuable features are that it's very simple to use and the user interface is very good, particularly for beginners so they can start the application easily."

"The vulnerabilities that it finds, because the primary goal is to secure applications and websites."

"This is a very mature tool; it is capable of facilitating the work of many security experts, and I highly recommend it for beginners and advanced users when some other tools fail to catch traffic."

"The reporting is quite intuitive, which gives you a clear indication of what kind of vulnerability you have that you can drill down on to gather more information."

"Zap is an open-source and sophisticated product that not only saves us money but also provides us with a good amount of information."

More OWASP Zap pros

Cons

"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."

"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."

"ImmuniWeb sometimes shows previous scans instead of running tests."

"The product’s interface for the web applications could be similar to Android and iOS versions."

"You may find the dashboard a bit complicated."

"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."

"Its technical support could be better."

More ImmuniWeb cons

"Online documentation can be improved to utilize all features of ZAP and API methods to make use in automation."

"Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."

"Zap is very good for a beginner, but once you start moving up the ladder where you want further details and you want your scan to show more in-depth results, Zap falls short because its coverage falls short."

"Too many false positives; test reports could be improved."

"OWASP Zap needs to extend to mobile application testing."

"I would recommend this product to people although I think it is very difficult to deploy and we also have issues with maintenance."

"Deployment is somewhat complicated."

"It would be nice to have a solid SQL injection engine built into Zap."

More OWASP Zap cons

Pricing and Cost Advice

"I use the product's free version. The tool costs around 229 dollars."

"ImmuniWeb is relatively cheap. It's a competitive price compared to other products in the marketplace. It's worth the money we are paying for it."

"It is pretty expensive."

"There should be the flexibility to change or add pricing, especially for pay-per-use cases."

"The platform is expensive if a large development is involved. However, it is less expensive for scheduled-based testing, quarterly or in a year."

"The values of ImmuniWeb are currently significantly below what is valued in the Chilean market for these services and solutions."

"It is pretty expensive."

"It is open source, and we can scan freely."

"OWASP Zap is free to use."

"The solution’s pricing is high."

"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."

"The tool is open source."

"It is highly recommended as it is an open source tool."

"As Zap is free and open-source, with tons of features similar to those of commercial solutions, I would definitely recommend trying it out."

"This solution is open source and free."
