We use Qualys Internet-based scanners for external penetration testing as well as PCI scans for our clients. The tool being Internet based, it can be accessed from any location, and it does not have issues with updating the patches as well as versions (QualysGuard updates the tool at specific periods in a year with prior information). The report generated by QualysGuard is very detailed and easy to understand.

868,787 professionals have used our research since 2012.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
The product that we used in our office under different environments is highly stable.
What do I think about the scalability of the solution?
This product is designed for easy scalability and can easily scale up without major challenges.
How are customer service and support?
We have experienced quick customer support. They have a complete list of our previous issues along with our history, which makes it faster for them to solve issues.
How was the initial setup?
It is a straightforward implementation. Once you register over the Internet, they assign you a set of static IP addresses which can be used to perform web-based scans. The administrator panel is easy to understand and create.
What's my experience with pricing, setup cost, and licensing?
It is best to be an institutional buyer and directly contact the sales team, as they can provide over-the-top discounts for bulk orders.
Try the free trial of the product to understand the basic working mechanisms.
Which other solutions did I evaluate?
We did try Acutenix, but the quality of results and user interface of Qualys was excellent in comparison.
What other advice do I have?
We are an institutional partner of QualysGuard and buy bulk licenses.

We’re a Linux shop and Qualys gave us good Linux vulnerability scanning; no experience with it on MSFT products.
What is most valuable?
We’re a Linux shop and Qualys gave us good Linux vulnerability scanning; no experience with it on MSFT products. It reports only a few glaring false-positive errors (directory ownership was a common one), and our post-processing dealt with the known exceptions we’d agreed on. The long baseline of iterative results was valuable to track changes and our rate of improvement. Access to the API let us automate its use in our CI/CD pipeline for machine images.
How has it helped my organization?
The biggest benefit was integrating Qualys scanning into our CI/CD pipeline to vulnerability-scan new custom machine images (for OpenStack or AWS) before deployment. We’d build the image, instantiate it, run Qualys against it, get the report, post-process it, look for new errors or changes (if any), review just those and either block deployment or update our exceptions list for next time.
What needs improvement?
The licensing and user permissions are a little wonky for a DevOps team to use, probably because it’s traditionally an InfoSec tool.
For how long have I used the solution?
Symantec has run Qualys Enterprise against our private OpenStack cloud for at least three years; we started using the Qualys VA on AWS in 06/17.
What do I think about the stability of the solution?
Only those which Qualys scanning revealed in our OpenStack implementation.
What do I think about the scalability of the solution?
Not really, we spun up multiple Qualys servers to walk through our data center cloud infrastructure on a regular basis.
How are customer service and technical support?
Pretty poor, as usual for almost all software products now. Getting past the Tier 1 and 2 call center people is always a challenge, so throwing the company name around isn’t a bad idea.
Which solution did I use previously and why did I switch?
Don’t know what, if anything, preceded Qualys at Symantec.
How was the initial setup?
It took about a month to get the Qualys scan completely integrated and automated in our CI/CD pipeline, but much of that was due to licensing issues and poor API documentation, not the product installation itself.
What's my experience with pricing, setup cost, and licensing?
The “bring your own licenses” model for the virtual appliance isn’t what you might think, so get a clear explanation up front before assuming you can go use virtual appliances on AWS.
Which other solutions did I evaluate?
Yes, the Symantec Global Security Office (GSO) did this, and I don’t know who else they looked at when the selection was made.
What other advice do I have?
My team was responsible for operating the Symantec development hybrid cloud (about 6K servers in four DCs and multiple AWS regions). We use Qualys Enterprise to scan our private cloud infrastructure and machine images, and the Qualys Virtual Appliance to do custom AMI validation before deployment in AWS. I don’t recall which versions we used but we kept them up to date.
I give them a seven out of 10. The product is pretty good, but not great. It simply isn’t feasible for a tool like this to be accurate (no false negatives, few false positives), so you wind up doing a fair amount of post-processing of scan results. The profile update cycles are not what I’d like to see, so the vendor isn’t reacting to new threats anywhere near fast enough.
Also, look at other vendors, of course. Tenable was getting a lot of good buzz at Symantec last year. Be clear in advance on how much “overhead” you’re willing to pay in order to run “regular” scans on your DC machines and networks. In the cloud space, it’s somewhat better to verify the base image once, and focus on application vulnerabilities, where possible.

It showed us vulnerabilities that we were not aware of and did not know how to test for. The organization of the assets was a little confusing and overwhelming.
What is most valuable?
- Ease of use and setup
- Visibility into our environment
How has it helped my organization?
WAS gave us visibility into our externally exposed web applications and showed us vulnerabilities that we were not aware of and did not know how to test for. We didn't need any knowledge of these vulnerabilities or how they worked to scan for them and to gain the visibility.
What needs improvement?
The organization of the assets was a little confusing and overwhelming. The system could also use some work in pivoting from a VM scan to add the servers with web applications exposed to the WAS server. It frequently created WAS assets that did not have web applications.
For how long have I used the solution?
I have been using it for 18 months.
What was my experience with deployment of the solution?
Scalability would be tough because of how the endpoints are organized. We did not have any issues with deployment or stability.
How are customer service and technical support?
We had a dedicated Technical Account Manager and the support was great.
Which solution did I use previously and why did I switch?
We did not previously use a different solution.
How was the initial setup?
Setup of WAS is pretty straightforward and only the organization of endpoints is a bit complex.
What about the implementation team?
Implementation was very simple because we were only using the cloud product and did not have any on-prem scanners.
What was our ROI?
Being able to gain visibility into our environment created a great ROI and licensing for us was competitive, but would have made it tough to scale to our whole internal environment.

It reports fewer false positives than other tools. The tool should have a live HTTP editor and more mature APIs.
What is most valuable?
There is nothing out of the box in the Qualys web application scanning module. One good thing is that it reports fewer false positives.
How has it helped my organization?
We use many other products along with Qualys. In a way, Qualys dashboards are good to keep track of vulnerabilities found asset-wise.
What needs improvement?
The tool should have a live HTTP editor and more configuration options for some situations, such as handling applications that have URL rewriting enabled.
The tool should have more mature APIs for integration and automation. They should provide more flexible APIs to download reports.
For how long have I used the solution?
I have been using it for almost four years now.
What do I think about the stability of the solution?
Qualys is good, stability-wise.
What do I think about the scalability of the solution?
Qualys is perfect, scalability-wise.
How are customer service and technical support?
On a scale of 1-5 with 5 being the highest, I would rate technical support at 3.
Which solution did I use previously and why did I switch?
I have used Nessus, Burp Suite, and IBM AppScan. Cost- and functionality-wise, I find Burp Suite the best of them all. AppScan is good, but very expensive and reports more false positives.
How was the initial setup?
Setup is straightforward.
What's my experience with pricing, setup cost, and licensing?
Licensing could be cheaper. It is expensive at present.
What other advice do I have?
Qualys is only a good product for in-house vulnerability management programs. It is not feasible to use Qualys for client-facing consulting engagements because of the cost.

Which solution did I use previously and why did I switch?
I used Rapid7 NeXpose in another shop.
How was the initial setup?
The product was already installed when I got there, I just added more scanning jobs and used the reports for remediation, etc.
Which other solutions did I evaluate?
I evaluated and selected Rapid7 NeXpose in a previous job (over QualysGuard) because the compliance department there vetoed using “an external service”. Also, we wanted to get Metasploit later.

Premature product - not a proper product to be used for PCI approved Web Scanning
v2 Review: Premature product - not a proper product to be used for PCI approved web scanning
Having done numerous penetration tests using various manual and automated tools, today we are focusing on a new tool called QualysGuard Web Application Scanning v2.4.1. In the process of doing a pentest, we often use a quality automated tool to check for standard issues while we focus on the much more difficult issues of the testing. As this reduces the time it takes to do a full test, allows us to work more efficiently, and besides who wants to waste time doing monotonous simplistic checking. In this regard, I have used AppScan quite extensively, and HP WebInspect as well, and both are very good tools for the most part. They help out on the basic checks quite a bit.
Quite recently, I was introduced to QualysGuard Web Application Scanner (WAS) v2.4.1. This tool was very simple to use which is true to Qualys name. Point and click and you are done. Unfortunately, I found out that it didn't help with the standard checks either.
Problem #1
1. It couldn't even authenticate to basic web forms. I've used AppScan on hundreds of sites, and not once was there a problem in not being able to authenticate. A web security tools isn't very useful if it can't get passed the logon screen because that's where most of the application resides. How is it supposed to check anything if it doesn't get passed the logon screen' The Qualys product support/product manager's response to this is to use Selenium Scripting. Unfortunately, the current applications that are being tested only run on Internet Explorer (IE) and Selenium scripting automatic record and playback only works on FireFox. So one must learn a new scripting language in order to make it work with IE. This is hardly an easy point and click solution. Learning a new scripting language is time consuming and error prone. Other professional web scanners have this feature built in.
Problem #2
2. It cannot do a manual explore like other professional tools. For instance, manual explore is needed to fill in certain forms properly in order to get to the critical screens for testing. For example, you must fill in a proper social security number to look up the customer and get to the rest of the application. Qualys WAS does not support this feature. This web scanner doesn't allow the user to fill in the initial forms with proper data thereby never testing the whole application, which is critical. The Qualys product support/product manager's response was this is a simple point and click tool, "we don't support nor do we plan to support complex features such as manual explore."
Problem #3
3. Web service scanner has limited functionality in comparison to other professional tools. In this day and age, many web applications use web services. To not support this feature properly is ridiculous. The Qualys product support/product manager's response, "we only support web service fuzzing at this point." What about testing authenticated web service calls' It also doesn't support pre-populated data on web pages not web services other than the logon screen. This pretty much reduces their web service testing to a dummy tool. To make this work, you have to use tools like SOAPUI or Burp Suite Pro with scripting/plugins to pre-populate data, manual explore, and sequence test steps.
Problem #4
4. Lack of details provided by Qualys.
a. Most professional tools have an audit log that shows exactly what tests were performed and how they were performed. Qualys does not provide an audit log of what tests they did. We are supposed to guess instead as to what might have actually transpired. Real reason behind not providing an audit log is more likely along the lines of they don't all the check they are supposed to and even if they did, it probably wasn't exhaustive testing of say XSS. Either way, we have no idea whether they did the work they claimed to have or not. A Big Mystery Here!
b. No details provided on the actual request/response when a vulnerability is found. True to Qualys name of simplicity. The vulnerability finding is so simplistic and lacking any details as to how it was tested, one wonders how to test whether this finding is a false positive or not. Well, I guess one is supposed to take Qualys word for it. :)
Problem #5
5. Missed critical session management vulnerabilities. Qualys missed a critical session management vulnerability that I had to find manually that AppScan would have found. The Qualys product support/product manager's response, "we are putting in a fix for this soon."
All in all, QualyGuard Web Application Scanner (WAS) v2 is lacking quite a bit in terms of quality and details. Do you want to risk the security of your enterprise by relying on a product like this' Currently, the product is premature and should not considered to be a proper product to used for PCI approved Web Scanning. In fact, it should not even be PCI approved until it matures quite a bit. Qualys needs to understand how a true web application scanner works before releasing a premature product to cash in on a exploding market.
