It improves the continuous monitoring of the systems on-premises.

It has a quicker response time to incidents. And it has a stable performance record.
Pros and Cons
- "I find the most valuable features are the continuous monitoring. Even on premises, there is constant monitoring."
- "They have integrated with other third parties, but it is still not viable."
- "When tested on Zero day, there were errors."
What is our primary use case?
How has it helped my organization?
If any anomalies are there, we can easily detect with our agent based solutions, and we can isolate them quickly, and response time or any incident is much quicker than previous. Before we were taking eight hours, now we're taking around 30 minutes to respond to any incident, security and such.
What is most valuable?
I find the most valuable features are the continuous monitoring. Even on premises, there is constant monitoring.
What needs improvement?
When tested on Zero day, there were errors.
In addition, they have integrated with other third parties, but it is still not viable. They are using their own Q id's. This sometimes leads to a false positive. And, even the updating of signatures into Qualys is not that much quicker. Maybe for Windows and Linux, it is a little quicker or networks and other devices. The signature updating is not quicker.

ITSM & AntiFraud Consultant at a tech company with 51-200 employees
Vulnerability management is the most valuable feature but it would be good if they could provide an internal computing appliance.
Pros and Cons
- "Vulnerability management is the most valuable one and it’s a must in every organization."
- "One of the biggest issues from the clients' perspective is that all Qualys computing is on the cloud."
What is most valuable?
From my point of view all the Qualys products are valuable. From the clients' perspective, I believe vulnerability management is the most valuable one and it’s a must in every organization. After the client realize the risks from outside, and that the vulnerabilities are real, a proper compliance policy implementation using Qualys Policy Compliance (I'm using v8.4), the second product needed in any infrastructure, can be done. If the organization has public websites, Web Application Scanning (I'm using v4.1) is the third valuable product needed in an organization.
How has it helped my organization?
After the first scan of the servers at all the POCs QualysGuard discovered many vulnerabilities that are grouped from low to high impact. The ability to use asset management to scan the grouped servers from the vulnerability management feature with the policy compliance engine helps the security officer to perform the daily/monthly tasks faster and make them more organized.
What needs improvement?
One of the biggest issues from the clients' perspective is that all Qualys computing is on the cloud.
As last month ( this is when I found out) Qualys offers a On-Premise instalation for it's customers.
https://www.qualys.com/enterprises/qualysguard/pri...
The issue with the private cloud is that is costs very much for a small firm.
For how long have I used the solution?
I have been using QualysGuard since 2012, and I have followed the certification from Qualys in class. After that, I implemented it for one of our clients, and did some POCs using Qualys. In the last month I had another PoC with Qualys and the client looks interested.
What was my experience with deployment of the solution?
need support from sysadmin to deploy the ovf file.
What do I think about the stability of the solution?
Qualys appliances are based on Linux OS, and they are very stable. I didn’t encounter any stability issues.
What do I think about the scalability of the solution?
The big advantage of using the virtual appliances is that you can increase the allocated hardware if you need more resources.
How are customer service and technical support?
Customer Service:
The customer service level is very high. All the requests made to the reseller were fulfilled in a very short time.
Technical Support:We didn’t need to use Qualys technical support as the product was very stable, and our knowledge of the product was enough to fulfil all the clients needs.
Which solution did I use previously and why did I switch?
I have used both Nessus and Rapid 7 Nexpose. I am working as a security consultant and I need to know the big players so I could present to my clients the pluses and minuses of the products they might choose.
How was the initial setup?
Qualys initial setup is straightforward and if you follow the manual you don’t have any problems. You receive the credentials, login to the Qualys website, download the virtual appliance, configure the IP, and, after defining the credentials and the assets, you can start scanning your environment. For the hardware appliance you have to connect it to the network and after the configuration you can start the scanning.
What about the implementation team?
I was part of the consultant team that implemented this solution to the client. We didn't have any complaints from him, and he used us to implement the rest of Qualys' components.
What's my experience with pricing, setup cost, and licensing?
Usually every implementation is different and the quote is in function of number of assets.
Which other solutions did I evaluate?
The clients are usually evaluating the top three vendors from Gartner. From my clients side, the vendors used in evaluation were Nexpose, McAfee Vulnerability Manager and Nessus. Also I have tried the open source VM OpenVAS
What other advice do I have?
Follow the vendor provided steps, and you will not have any problems during the initial implementation. If you don’t have experience with server policies, use a consultant that will be able to identify your business needs.

What do I think about the scalability of the solution?
I have not encountered any scalability issues.
How are customer service and technical support?

Which solution did I use previously and why did I switch?
We previously used Rapid 7. The product was not staying current with shifting trends, sales staff were pushy and management were arrogant.
How was the initial setup?
Initial setup was simple.
What's my experience with pricing, setup cost, and licensing?
Negotiate for the pricing model that fits your budget. The vendor is willing to customize pricing.
Which other solutions did I evaluate?
Before choosing this product, we evaluated Rapid 7, Nessus.
What other advice do I have?
Take your time and have each vendor set up an actual proof of concept, rather than just relying on a demo. Get your network and support staff engaged in the process early on because they will be instrumental in deployment and support. Know what you’re trying to accomplish.

Sr. Analyst- Security Testing with 1,001-5,000 employees
The reports it generates give us a detailed description of and solution for all network and compliance-related violations, though I'd like an exploitation framework.
Valuable Features
QualysGuard provides a solution for network security, web application security and compliance.
Vulnerability management and policy/PCI compliance are the features that I have used which I think are the most valuable.
Improvements to My Organization
We use QualysGuard to identify all network and compliance-related violations of the assets. The report generated by the product will have a detailed description and solution. This has helped us to provide a certificate of compliance or a clean sheet for our vendors.
Room for Improvement
I'm looking forward to having an exploitation framework, a platform/framework that helps to cross verify the vulnerabilities like Metasploit.
