Qualys TruRisk Platform (formerly Qualys Cloud Platform, or Qualysguard), from San Francisco-based Qualys, is network security and vulnerability management software featuring app scanning and security, network device mapping and detection, vulnerability prioritization schedule and remediation, and other features to provide vulnerability management and network attack surface reduction.
Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.
Qualys Cloud Platform is well suited for organizations that need additional tools to secure and bolster their security from end to end. The automated, real-time threat protection is very quick to notify an admin of potential vulnerabilities and risks, as well as recommending quick fixes to resolve/close the gap before an incident occurs. QCP excels at portraying all of these in a single pane of glass, and find that the Qualys reports are more detailed than competitor product lines. One of our big issues with QCP is that you do have to pay for each scanner, which can quickly add up to large costs. For this reason, I would rate Qualys at a ~7 due to great features and functionality, but overall value could be better for a large organization. I would also say that QCP may make more sense for smaller organizations due to this pricing model.
It really does well at vulnerability scanning, which it is well known for. It's accuracy at finding vulnerabilities is top notch, more so than a lot of other vulnerability tools out there. In an organization/company you want this kind of accuracy at finding vulnerabilities in your network/endpoints
It is very good at managing endpoints on a consistent basis, meaning you can add endpoints to Qualys and have the platform scan/track/protect for vulnerabilities on an ongoing basis, without user intervention
It does really well at separating out and identifying what levels of criticality each vulnerability should fall into. This way, an organization/company can attack the more critical vulnerabilities first
Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.
This program is really complicated, the multiple functions that are presented to us are not very clear and in some cases, it is a matter of intuition to execute a function, it is not very informative.
The interface of this program can be a real problem; for our taste, this program looks a bit messy, and the interface does not help or guide you to find the options you need.
We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.
The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.
Again, the usability of Qualys has been a pinpoint for this entire review. It was easily the worst thing about the product and because of this, I would not recommend Qualys to anybody in my field. This should be something that Qualys strives to improve if they wish to stay in business.
I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.
They had a support page within the WAS to report any concerns or seek help. But the UI of that is not smooth. Regardless support staff were pretty responsive and helpful. They scheduled calls to understand and address our problems. Email support is good as well.
Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].
As described before Qualys is used to scan periodically the environment in order to check if there are some packages (Linux) or Applications (Windows) outdated, generating reports to the Service Owners, fulfilling what's is expected from us, attending all our expectations regarding the tool. That's why we'd choose Qualys to our organization.
With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
You can set up as many alerts as you want without incurring any fees.
