Checkmk vs. Qualys VMDR vs. Tenable Nessus

In our organization which is a mash up of different hardware, software it was important to use an independent tool that wasn’t linked to one manufacturer incase a piece of hardware was dropped from support for example, we also value open-source software highly in our field. It’s important to in our IT environment to be able to customize and tweak software that we run. We don’t use the cloud monitoring aspect so Cannot comment on that side of the software.

Qualys VMDR is best suited for larger companies with a very large IT asset footprint. Qualys VMDR is not suited for businesses that are small and upcoming as the price for the tool is very expensive and could be a budget sink if not used properly. In our organization we use the Qualys VMDR dashboard and reporting in order to collect any vulnerabilities we miss during our routine audits to ensure that our environment is stable and protected for attacks.

It is an excellent tool for scanning servers, workstations, and network devices to identify missing patches and misconfiguration; we regularly use it to confirm patch effectiveness after the update; it also helps us for preparing audits such as iso 27001, and regulatory requirements, it also helps us to identify open ports and services that violate security.

• Seamless reporting across the different widgets (i.e. TruRisk)
• DEEP-DIVE into an asset's info/vulns
• Baked-in PCI ASV scans that a Qualys QSA can approve

• Nessus is best at performing vulnerability scans, in fact, it gives findings and moreover accurate findings of the assessments. It does not do penetration testing or exploit the vulnerabilities because it is concerned about scanning the systems/applications.
• In fact, Nessus has multiple profiles/policies to perform different types of scans such as, scans oriented for PCI-DSS, malware scans, web application scans, bad shell shock detection scan to name a few.
• Nessus has the ability to classify the vulnerabilities into risk-based categories from critical to even informational which I think is one of the things that separates Nessus from other vulnerability scanners.

• Updates
• mobile interface
• Agent for android devices

• Qualys VMDR can definitely improve on its reporting of assets as we have caught devices not captured in the Qualys VMDR scans.
• We would like to see an improvement on the dashboard interface as it is faulty sometimes.
• Qualys VMDR should focus on more competitive pricing as it is very expensive.

Incentivized

• The tool has lots of options for setting up before scanning any device, this methodology could be simplified further with default configuration for various devices predefined, anyhow we can use this technique by making use of policies.
• For advanced users we cannot disable the plugins inside the plugin groups, we can enable the whole set of plugins at a time, for few hundreds its ok, but thousands of plugins are of waste of resource and time.

Very helpful software and I highly recommend to have on hand as a tool for testing, troubleshooting, and monitoring.

Next to Veeam (which is a tremendous product for backup/DR) this is the best service/software I have used in the past three decades. Should be called the Swiss Army Knife of security.

Nessus is best and easy to use application for Vulnerabilities finding and reporting, it has multiple platforms and wide scope covering almost all devices for security improvement so far, thus we are very likely to continue its services.

Overall Checkmk is a great product that is made and ran by a European company that is open source and highly customizable, great support if needed. On prem support is a must for our organization which Checkmk supports. Our organization has been using Checkmk for over 5 years now Performance of the software runs excellent on its own Linux server, for any company with a good Linux admin, you can have a lot of un tweaking and creating custom checks for every aspect of your environment.

infrastructure to identify vulnerabilities

Tenable Nessus is a great product and provides a lot of value, but it is difficult to set up and use and the amount of data it generates can be overwhelming. It does help us prioritize based on the severity of the detection, however there are sometimes mitigating factors that we have implemented that Nessus does not account for, which causes lots of noise in the reports.

This is iron but I am giving it 5 star and I can give more If I can do because they are best in support. So once you own this product they will assign a dedicated support for you and when you are under the weather with anything just connect them with anything call, ping or ticket they will come like Genie.

I haven't needed to contact support yet. But issues are easily solved with a quick internet search which means support and by extension, the larger community are involved and knowledgeable.

Not really - the integrations via connectors is not heavy lifting. Any complexity has to do with a service that requires more steps (i.e. AWS/GCP)

Checkmk free version is far superior to PRTG free version. For the paid versions PRTG was more efficient and easier to use. Checkmk provides unlimited services on their free version while PRTG is limited. We like to use the free version to avoid monthly or annual costs while still utilizing the same SNMP features.

It is a very similar tool but Qualys VMDR is much better when it comes to reporting and solutions provided. Asset management is really good in Qualys VMDR. Qualys VMDR support is really quick , you can get a TPM if you run into any issues. Qualys VMDR has wide variety of scanning options which lacks in tenable.

Sometimes when we identify a vulnerability with Nessus that has an exploit, we made a proof of concept with Metasploit in order to show to the IT managers the importance of the software/hardware hardening.

MOSTLY good - but as noted having all features purchased on portal only - nothing that is not purchased.

Outside some pretty arcane apps or OS this is painless. The problem - and self-inflicted - is that older stuff is not supported.

• avoid downtime
• Plan updates based on usage of a VM or network switch to avoid impacting users
• User satisfaction increased due to less visible downtime or issues with our IT infrastructure.

• Cut down on manual efforts to investigate or remediate vulnerabilities, which can be a big driver of ROI
• Avoidance of potential incidents with upfront risk mitigation
• Patching efficiency gains

• Nessus certainly has a positive impact while me while performing my job, either as security research, or performing vulnerability assessments for clients. It gives a lot of information about the system/application after performing scans. The number of false positives is also less compared to other vulnerability scanners.
• The professional edition is very useful as policy templates available in this edition are very handy and useful even to perform compliance scan like PCI DSS scan.
• Also, the ability to export the scan results into reports in formats like HTML, PDF is very useful which could be for performing system/application reviews.
