CrowdStrike Falcon vs. Tenable Security Center vs. Tenable Vulnerability Management

CrowdStrike Falcon is ideal for large, cloud-native enterprises that prioritize advanced behavioral detection and have a mature SOC to manage their intelligence. However, its cloud-reliant architecture makes it a poor fit for air-gapped or offline networks. Additionally, small organizations with limited staffing may find it difficult to manage, while teams that require integrated SOAR and vulnerability management might be discouraged by the need for additional licensing to unlock those capabilities.

Tenable.sc is best suited for those organizations who are not very comfortable with Cloud and want an on-premises solution. If any organization has to follow some guidelines that no data should go to the cloud, in this case, Tenable.sc is a perfect fit as it's installed in the infra Datacenter and no data goes to Cloud. Tenable.sc won't be appropriate for those who have their infra setup on cloud.

Tenable.io is a cost effective Internal and External scanner. The Internal scanner came with a .ova, so it was very simple and quick to deploy it into our ESXi environment. It has a cloud-based dashboard for management and the internal scanner is configured to auto-update from Tenable.io. The license came with 4 External PCI scans (with remediation) a year.

• Great threat intelligence which is very up-to-date with the recent cyber attacks
• very user friendly in access and management
• Automated feature of detecting, taking action and closing incidents using fusion workflow.

Incentivized

• Vulnerability management from one place
• Maximum endpoint visibility
• Easy to set up and plan the structure
• Support desk quickly responses
• Well-prepared documentation
• Broad scanning type
• Supports various compliance standards
• User groups allows coordination between teams

• Wide range of capabilities that can be customized to fit each user's environment and needs
• Provides high-quality data and insights into detected vulnerabilities
• Great customer support

Incentivized

• The Dashboard can become overwhelming at times, too much information to absorb
• Computers that may have made it out into the field without the endpoint sensor are very difficult to find
• As with all systems that rely on machine learning false positives occurr

• Tenable could make it easier to report on missing reg key.
• Tenable can also make it easier to report on os level patches vs application patches.

Incentivized

• Configuration is not always intuitive, but the comprehensive training and documentation comes to the rescue.
• The mix of classic and beta UIs currently is confusing and we find the classic UI is actually better.

Crowdstrike has a large suite of tools built for helping the engineers triage and respond to security event whenever identified. The ability to customize the security policies and implement more granular policies to different devices based on the functionality is unmatched. Crowdstrike provides so much of ability in a decent budget which ascertains the value for money or ROI.

We like to renew tenable each year we have had it so far.

I think it is a complete and very trustful XDR platform, with very few False Positives. It is very well supported by highly skilled professionals on all levels: from pre-sales engineers, Customer Account Managers and support engineers.

Overall it is good, it took a little while to understand it and figure things out but once you have a good grasp on it then, it is very good.

Support is generally pretty fast and gets right to the issue. We haven't had to use them much, fortunately, but the issues and questions we've had are usually answered quickly. The customer success manager/account manager you're assigned will also follow up with you on a regular cadence to ensure you're getting the most out of the subscription. There's not a whole lot of room to improve, other than the general confusion about what is/what is not covered in custom packages you're subscribed to. The initial purchase took much longer because of a package name changes and realignments of different modules into those packages.

On all of the occasions that I have had to reach out to Tenable for assistance, they have been extremely helpful and knowledgeable. Solutions and support are provided quickly, and they work on the issue until it is resolved.

Support is usually really great at walking you through any steps you need to take when you get stuck on something. There are a few false positives and errors that have come up over the years that required their help to get through. Unfortunately, the steps required to diagnose some problems are more tedious than I think should be necessary. (IE: SQL instances can throw errors that clog up your logs because one plugin affects it in a certain way. The process to diagnose this is to watch timestamps of plugins in a log while monitoring the SQL logs at the same time and using your best guess as to what is causing it.)

There is limited amount of learning that can be completed in an in-person training available. In my opinion, the self-paced learning provided by Falcon portal is more useful over in-person training. The support from Falcon is great and useful to overcome difficulties, if any.

Incentivized

The training provided by Crowdstrike Falcon is complete in terms of the depth of technical knowledge and teaches the users about going through with the platform. There are lots of jargons for different tools that Crowdstrike Falcon has and this training teaches them all which helps in managing the platform better. Plus, the regular knowledge checks are also very helpful for the end user.

I have evaluated Cortex XDR and SentinelOne Singularity alongside CrowdStrike Falcon, and while all three are capable enterprise-grade solutions, Falcon ultimately stood out due to its cloud-native architecture, broader modular coverage, and stronger identity-focused detection. Cortex XDR performs very well in environments already heavily invested in the Palo Alto ecosystem, particularly for network-to-endpoint correlation, but it introduces additional complexity and infrastructure overhead. SentinelOne excels in autonomous remediation and offline protection, especially with ransomware rollback, but is more endpoint-centric and comparatively limited in native identity and exposure-risk context. CrowdStrike Falcon provided the best overall balance by combining NGAV, EDR, identity protection, exposure management, threat intelligence, and managed hunting within a single lightweight agent and unified console, enabling better scalability, faster investigations, reduced tool sprawl, and stronger protection against modern identity-driven attacks, making it the most aligned choice for our security and operational objectives.

Tenable.sc [(formerly SecurityCenter)] has been around for a long time and in our opinion offered the easiest configuration for compliance scanning and it's rating system was more impressive than Rapid 7's.

I think Tenable and Qualys have a lot of similarities, I continue to go back to Tenable because of my familiarity and comfort level with it. I've also used a company called SecurityMetrics which has vulnerability scanning included but it is not as comprehensive as Tenable.

• Due to some of the difficulties with Support and Sales, we are likely looking to change to another vendor. We sometimes don't feel like customers.
• When the bluescreen incident occurred (worldwide outage) in July 2024, we were unable to contact support due to the high volume of calls at the same time. We had to figure out how to remediate it ourselves, which we did, and recovered before the vendor's official release of fixes. It shook my confidence in them.
• The product itself performed well over the last 2 years, which has kept us safe and productive. The product is good.

• Create internal/operational efficiencies
• Improve compliance & risk management
• Cost management
• Solid vulnerability scanner
• Ease, of use, and capabilities when it comes to analyzing vulnerabilities is what makes this product stand out

Incentivized

• We're able to mitigate over 90% of our vulnerability risk without too much effort. It helps find where automated patching fails and we can plan a fix from the findings.
• A side effect of our scanning reveals new devices on our network that aren't cleared to be.
