It's running on my system. I use it to scan URLs and can check things if I find something.
Information Security Professional at AEDC
Fast and easy to set up but uses a lot of memory
Pros and Cons
- "You can run it against multiple targets."
- "There isn't too much information about it online."
What is our primary use case?
What is most valuable?
There's a way to set up jobs where you can get it to run all the processes against the target to avoid doing so manually. You can run it against multiple targets.
It is easy to set up.
The solution is stable.
What needs improvement?
I don't have any notes for improvements.
It should have more visibility. Everybody defaults to Burp. However, this is a free version that deserves more visibility.
There isn't too much information about it online. You need to self-teach in order to really learn how to use it. There isn't a lot of documentation available.
It takes up a lot of memory and RAM.
For how long have I used the solution?
I've been using the solution for roughly six months. I've used it on and off. However, I really started using it constantly over the last six months.

What do I think about the stability of the solution?
The solution is mostly stable. However, it requires a lot of RAM and memory. There are no bugs or glitches.
What do I think about the scalability of the solution?
It is not very scalable.
I'm the only security engineer. Only I use it in my company.
How are customer service and support?
I've never used technical support. I'm not sure how helpful or responsive they are.
Which solution did I use previously and why did I switch?
I used to use Portswigger Burp. This solution is free and has a lot of the paid versions Burp offers. I haven't used Burp Professional. I used the community version. I chose this solution as it is faster, at least compared to the community version. My understanding it the paid version of Burp is very fast.
How was the initial setup?
The initial setup was very simple and straightforward. I didn't find any difficulty installing it on my system.
It takes about ten to 15 minutes to deploy. It depends on the machine you have.
What's my experience with pricing, setup cost, and licensing?
The solution is free to use. I don't pay any licensing fees.
What other advice do I have?
I'm an end-user.
I'm not sure which version of the solution I'm using.
I would rate the solution seven out of ten. While it is free to use, it does take up a lot of memory. I also find Burp easier to use than this product.

Disclosure: My company does not have a business relationship with this vendor other than being a customer.
Great HUD feature that provides on-site testing and saves a lot of time
Pros and Cons
- "The HUD is a good feature that provides on-site testing and saves a lot of time."
- "The HUD, Heads Up Display, is a good feature; it provides on-site testing and saves a lot of time."
- "There are too many false positives."
- "We get too many false positives and that should definitely be improved."
What is our primary use case?
We use this product for vulnerability scanning and for testing. I'm an automation engineer.
What is most valuable?
The HUD, Heads Up Display, is a good feature. It provides on-site testing and saves a lot of time.
What needs improvement?
We get too many false positives and that should definitely be improved. I'd like to see site scanning included in the solution because it can get into your hidden files and reports.
For how long have I used the solution?
I've been using this solution for one year.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
The solution is not scalable.
How was the initial setup?
The initial setup is straightforward and was carried out in-house without assistance from a third party.
What other advice do I have?
It's worth exploring and learning the tool. It helps a lot to understand the vulnerabilities in the applications. I rate the solution eight out of 10.
Which deployment model are you using for this solution?
On-premises

Security Consultant at a consultancy with 10,001+ employees
Provides good information and is sophisticated; updates repositories and libraries quickly
Pros and Cons
- "It updates repositories and libraries quickly."
- "Zap is an open-source and sophisticated product that not only saves us money but also provides us with a good amount of information."
- "The solution is unable to customize reports."
- "The disadvantage of Zap is that we're unable to customize reports as it only has a single standard format."
What is our primary use case?
Zap collects all the AJAX and Ambelo GS links. It pages in everything from a target. I'm a security consultant and we are customers of Zap.
What is most valuable?
Zap is an open-source and sophisticated product. It not only saves us money but also provides us with a good amount of information. In terms of testing and attack simulations, it's pretty good. It updates its repositories and libraries pretty quickly.
What needs improvement?
The disadvantage of Zap is that we're unable to customize reports as it only has a single standard format. The default PDF template has no proper customizations, dashboards, or any sort of widgets that we can maintain. There's a single dashboard and only one type of report that it provides.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
We haven't had any scalability challenges.
How was the initial setup?
The installation was relatively easy as is maintenance.
What other advice do I have?
Whether this is a good solution depends on the use case. If an organization is looking for a professional license without putting down any money, this is one of the best solutions.
I would rate this solution more highly if we were able to customize reports. For now, I rate this solution eight out of 10.

Associate at Tata Consultancy
Scans quickly and works very well, but has a limited scope and needs more comprehensive reporting
Pros and Cons
- "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 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."
- "The work that it does in the limited scope is good, but the scope is very limited in terms of the scanning features. The number of things it tests or finds is limited. They need to make it a more of a mainstream tool that people can use, and they can even think about having it on a proprietary basis. They need to increase the coverage of the scan and the results that it finds. That has always been Zap's limitation. Zap is a very good tool 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. It does not have the capacity to do more."

Zap is a very good tool 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. It does not have the capacity to do more.
It should have more reporting options because the reporting options are currently only in HTML, XLS, and so on, but there is nothing in PDF or Word, which makes it a bit less user-friendly. It needs more comprehensive reporting. It already has a reporting system, but it is just not user-friendly.
For how long have I used the solution?
I have been using this solution for roughly 12 months. I am using the latest freeware version that is available on the website.
What do I think about the stability of the solution?
Its stability is good.
What do I think about the scalability of the solution?
It lacks scalability. It is only good up to a limit.
How are customer service and support?
Based on my interactions, they have been very good. They take around 24 hours to get back to you because they're a very large organization that is totally into this. They are quite good. They aren't the best, but they are quite good.
How was the initial setup?
Its initial setup was straightforward. It was pretty much immediate. There was no deployment issue. It was done quickly.
What about the implementation team?
It was implemented in-house. In terms of maintenance, it doesn't require much maintenance. You need just one person to follow the updates. That's about it.
What's my experience with pricing, setup cost, and licensing?
We have used the freeware version. I believe Zap only has freeware.
What other advice do I have?
My advice would be to not look at Zap as a one-stop-shop for all your results because Zap cannot do that. Zap is very good for a certain number of basic vulnerabilities or medium to high-level issues, but it can't go beyond that. You can use Zap along with another tool. If you're doing two or three levels of security testing, you can use Zap along with other tools.
It is more of a learner tool. So, if you're using Zap, it would be best if you use it as a beginner in the field. Once you get into projects or work for people on their applications, you'll definitely end up needing something stronger.
I would rate it a five out of ten.
Which deployment model are you using for this solution?

Provides visibility of queries, but security and the ability to search the internet for other use cases could be better
Pros and Cons
- "The solution is scalable."
- "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 ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed."
- "The computers perform somewhat slowly when loading a large number of queries into memory."
What is our primary use case?
The solution has certain models. It allows the creation of a pipeline in respect of the interface or of certain content. It enables one to check that the security is as it should be.
What is most valuable?
The solution enables a person to add the certificate and check the queries, to see if there are any that are undefined. This way, a person can have a list of the types of queries and can trace them.
What needs improvement?
The ability to search the internet for other use cases and to use the solution to make applications more secure should be addressed.
For how long have I used the solution?
We have been using OWASP Zap for more than four years.
What do I think about the stability of the solution?
The computers perform somewhat slowly when loading a large number of queries into memory. As such, I don't know if it will be possible to use cache on the disk, which would greatly increase performance.
What do I think about the scalability of the solution?
The solution is scalable. It can be run simultaneously for different targets.
How are customer service and technical support?
I have not had experience with using technical support. I make use of a public community on the public website.
How was the initial setup?
The initial setup is a bit complex, not straightforward. It could be made easy if, lets say, a project can be defined for a certain task through the project's creation. This may simplify its use.
Which other solutions did I evaluate?
Zap is a very good startup. There is an alternate solution that is a bit more expensive and requires more technical knowledge than OWASP Zap, although both have a model based configuration. The interface allows one to run predefined templates, something OWASP Zap has in common with the other solution. The automation capabilities are similar, as well.
What other advice do I have?
I used the source code design for the deployment.
I have not had experience with the code crawler, OSWAP Zap code analysis. The solution I was using is run by a search engine. My clients utilize OWASP Zap AST. They do not make use of the code crawler.
I rate OWASP Zap as a six out of ten.

Technical Specialist(DevOps) at a tech services company with 1,001-5,000 employees
Provides good automatic scanning and privacy; reporting could be improved
Pros and Cons
- "Automatic scanning is a valuable feature and very easy to use."
- "The automatic scanning is a valuable feature and very easy, and the major advantage to this solution is the privacy it offers."
- "Reporting format has no output, is cluttered and very long."
- "Without any support, we are in a black hole sometimes."
What is our primary use case?
We are using this product at a very basic level to scan reports and then share them with the Dev team for any vulnerabilities. We use the open source version and we are end users.
How has it helped my organization?
The solution has improved company functioning to a certain extent, but it takes a lot of time coordinating with the Dev team because we are using the open source version and not the enterprise version. It's not an awesome solution but we do get the reports we need and there is a good amount of documentation and support.
What is most valuable?
The automatic scanning is a valuable feature and very easy. The major advantage to this solution is the privacy it offers. We are able to achieve our objectives to some extent, but only for non-business critical applications.
What needs improvement?
The reporting format could be improved. There is no output, it's cluttered and it's a very, very long report. It would be better if it were in PDF format with a short description, some findings, color coding, and easy to read. What we do now is analyze the HTML report and then rewrite our own shorter reports. I work for a Japanese company and they want the important information to show up. The reports do not really give us recommendations or the points where the vulnerability is coming from so I'd really like to see an improvement in the condition of reports. We should be able to call an API from somewhere and scan applications.
For how long have I used the solution?
I've been using this solution for about one year.
What do I think about the stability of the solution?
The product is not that stable and sometimes I have to re-install it and contact the internal IT team. I don't have the admin rights on the laptop. Some features can break down, for example, the browser on the scanning might not open. Slowly our team will be moving towards more critical projects coming from the U.S., Japan and India, so we are definitely planning to upscale. In the next financial year, we're planning to upscale and make it more rigorous.
How are customer service and technical support?
We are using the open source version so we have no technical support for now.
How was the initial setup?
The installation is very simple. It's just an executable file because for now, we are not using it as a part of CACD or anything else. We have just installed the open source version on the laptop which has simplified things; our toolbox opens up and we just give the URL and it does an automatic scan. So information wise and operational wise, it is easy now. Our team carried out the deployment by first reading, watching videos and taking various courses. We had help from the company security team.
Which other solutions did I evaluate?
I carried out an evaluation between Checkmarx and OWASP Zap.
What other advice do I have?
If you are working in a very big gaming company and you have the budget, then I'd suggest switching to the enterprise version because the open source version takes time to resolve the regulations and there are sometimes false positives. It takes a lot of effort to figure out how to resolve the vulnerability and then search the same thing in the code. If you're not from the development team, then a lot of coordination is required. Without any support, we are in a black hole sometimes. Some attacks can be very dangerous for the company and for the application. They create delays and I've had to learn how to deal with that.
I rate this solution a six out of 10.

Assistant Vice President at Hexaware Technologies Limited
Great at reporting vulnerabilities, helps with security, and reveals development threats well
Pros and Cons
- "The solution is good at reporting the vulnerabilities of the application."
- "OWASP is definitely in the top three as a tool that we would probably recommend to our team, as a frequent users' tool, however, I don't believe we have any kind of a formal relationship with the company."
- "It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful."
- "Right now, I can't give it off to a team and expect them to give me a report that I'm happy with."
What is our primary use case?
Currently, we build our products for the banking industry and use this solution in that process.
From a development cycle, we update the SQL injections that basically shows what a developer may have to address. Then, if there is still a problem, we're concerned at the architect level. That's at least initially reported by the customers when they do another round of review after we deliver our code.
What is most valuable?
The solution is good at reporting the vulnerabilities of the application.
It can help us with security, SQL injection vulnerability, known vulnerabilities, et cetera. Any kind of a threat that we get in the development cycle, is what we will look for. This solution helps us find them.
What needs improvement?
I can't recall any features that are lacking. In my role as a service provider, I only go up to standards defined by somebody else. So far, this solution has met their standards.
So far I've not come across a scenario where we had to do anything that's a major rework due to the fact that we didn't catch something soon enough in the queries that we are using.
It would be ideal if I could try some pre-built deployment scenarios so that I don't have to worry about whether the configuration sector team is doing it right or wrong. That would be very helpful.
Right now, I can't give it off to a team and expect them to give me a report that I'm happy with. I will give it to a team and they will have to have another person sit with them to make sure they have configured it right. Some kind of pre-designed templates, pre-designed guidelines, or patterns to compliment the tool would go a long way in helping us use the solution.
For how long have I used the solution?
I've been using the solution for five or six years at this point.
What do I think about the stability of the solution?
From the perspective of the development cycle that we use, we find it stable enough. I don't use it in production or I don't have to update sites running all the time. Once a week when I will build a VM pack, I push into another environment, and that's probably the time I would make it. For me, I find it to be stable enough.
How are customer service and technical support?
I haven't really used technical support. Therefore, I can't really speak to their level of responsiveness or knowledgeability.
Which solution did I use previously and why did I switch?
I'm not a security specialist, however, to be clear, we provide services. On a development project, we frequently run into various solutions. It's not just OWASP. It could be Veracode, for example, or multiple other tools.
How was the initial setup?
The initial setup is not necessarily straightforward. Most are complex. You need a senior person to specialize, understand the set up in which they are running, and understand the tools they are going to use. You need to ask: do they know what to look for and support? I wouldn't say it's complex to use. That said, normally the resources are costly.
What's my experience with pricing, setup cost, and licensing?
In security, you'd expect the product is priced at a premium, so people don't check the pricing for the most part. In my case, I don't buy the product myself. I have the customers buy it for me. I'm not very worried about the price as a consultant.
What other advice do I have?
We are an IT service provider, which means that we use a variety of tools based on what our customer preferences are.
There's all, at most, I would say, about 20 companies that we would have the funds to use the solution with. OWASP is definitely in the top three as a tool that we would probably recommend to our team, as a frequent users' tool, however, I don't believe we have any kind of a formal relationship with the company.
Multiple teams use it. I have not heard of anybody complaining about anything to do with this particular solution. I would say it's pretty good. I would give it a rating of eight out of ten.

I have been using OWASP Zap for approximately three months.
Which solution did I use previously and why did I switch?
I have used other solutions, such as AngularJS.
How was the initial setup?
The installation is straightforward.
What's my experience with pricing, setup cost, and licensing?
This solution is open source and free.
Which other solutions did I evaluate?
I have been evaluating Armor for my teammates who are using ZAP. I have found that Armor is better than ZAP and we are looking to switch solutions.
What other advice do I have?
I rate OWASP Zap a six out of ten.
