Executive SummaryUpdated on Oct 19, 2025

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
6.5
Datadog enhances debugging efficiency, reduces downtime, and optimizes performance, though early ROI quantification can be challenging.
Sentiment score
5.3
Tenable Cloud Security is financially beneficial, offering cost-effective services and positive outcomes despite lacking specific recent metrics.
Previously we had thirteen contractors doing the monitoring for us, which is now reduced to only five.
Datadog has delivered more than its value through reduced downtime, faster recovery, and infrastructure optimization.
I believe features that would provide a lot of time savings, just enabling you to really narrow down and filter the type of frustration or user interaction that you're looking for.
 

Customer Service

Sentiment score
6.7
Datadog's customer service is responsive and knowledgeable, offering efficient support, though regional wait times can vary.
Sentiment score
3.4
Tenable Cloud Security support receives mixed reviews with praised efficiency and availability, but some note delayed and inconsistent assistance.
When I have additional questions, the ticket is updated with actual recommendations or suggestions pointing me in the correct direction.
Overall, the entire Datadog comprehensive experience of support, onboarding, getting everything in there, and having a good line of feedback has been exceptional.
I've had a couple instances where I reached out to Datadog's support team, and they have been really super helpful and very kind, even reaching back out after resolving my issues to check if everything's going well.
With Element, if you need a feature, you can discuss it with them, and if implementation is possible, you will have that feature within a month or two, depending on complexity.
 

Scalability Issues

Sentiment score
7.6
Datadog is highly scalable, integrates well with cloud services, but costs can rise with full data indexing.
Sentiment score
5.8
Tenable Cloud Security excels in scalability, praised for handling assets efficiently, but faces challenges in larger multi-cloud setups.
Datadog's scalability has been great as it has been able to grow with our needs.
We did, as a trial, engage the AWS integration, and immediately it found all of our AWS resources and presented them to us.
Datadog's scalability is strong; we've continued to significantly grow our software, and there are processes in place to ensure that as new servers, realms, and environments are introduced, we're able to include them all in Datadog without noticing any performance issues.
 

Stability Issues

Sentiment score
8.0
Datadog is reliable and stable, offering consistent monitoring with minimal downtime despite occasional minor issues.
Sentiment score
7.8
Tenable Cloud Security is stable and reliable, with high ratings and prompt resolution of minor bugs, say users.
Datadog is very stable, as there hasn't been any downtime or issues since I've been here, and it's always on time.
Datadog seems stable in my experience without any downtime or reliability issues.
These incidents are related to log service, indexes, and metric capturing issues.
In situations where there was a platform issue, they fixed it immediately and provided a complete explanation for the occurrence.
 

Room For Improvement

Users suggest improving Datadog's performance, interface, pricing transparency, documentation, integration, real-time visibility, error traceability, support, and customization.
Tenable Cloud Security needs improved speed, automation, integration, clearer licensing, better support, and AI-powered features for multi-cloud environments.
It would be great to see stronger AI-driven anomaly detection and predictive analytics to help identify potential issues before they impact performance.
The documentation is adequate, but team members coming into a project could benefit from more guided, interactive tutorials, ideally leveraging real-world data.
In future updates, I would like to see AI features included in Datadog for monitoring AI spend and usage to make the product more versatile and appealing for the customer.
Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable.
The only complaint I hear in the market is from resellers that Tenable management team in Brazil doesn't play fair with the channel and resellers.
 

Setup Cost

Datadog offers flexible pricing with reasonable costs, though complexity and fluctuating bills require careful monitoring and enterprise negotiation.
Tenable Cloud Security is favorably received for its fair pricing, offering good value for enterprise cloud security solutions.
The setup cost for Datadog is more than $100.
Everybody wants the agent installed, but we only have so many dollars to spread across, so it's been difficult for me to prioritize who will benefit from Datadog at this time.
My experience with pricing, setup cost, and licensing is that it is really expensive.
 

Valuable Features

Datadog excels with its intuitive interface, real-time monitoring, extensive integrations, customizable dashboards, and seamless system operations.
Tenable Cloud Security offers comprehensive vulnerability detection, asset management, and integration, enhancing security and compliance with proactive monitoring.
Our architecture is written in several languages, and one area where Datadog particularly shines is in providing first-class support for a multitude of programming languages.
Having all that associated analytics helps me in troubleshooting by not having to bounce around to other tools, which saves me a lot of time.
Datadog was able to find the alerts and trigger to notify our team in a very prompt manner before it got worse, allowing us to promptly adjust and remediate the situation in time.
The automatic integration capabilities, particularly with DNS, Azure, and AWS, are extremely valuable.
Perhaps the best functionalities are related to promoting a deeper analysis of the environment where applications are running in terms of creating a double armor of security to block threats that may come in the cloud with Tenable Cloud Security.
The best features Tenable Cloud Security offers in my experience are automatic scanning, frequent scanning, and automatic finding, which I find valuable.

Featured Reviews

Prakash Pandey - PeerSpot reviewer
Has improved monitoring accuracy and enabled faster issue resolution through detailed alerting and transaction visibility
The best feature that Datadog offers is infrastructure monitoring, where it can look at the CPU utilization, different process utilization, all the processes which are running, and alert us in advance if things are going beyond normal threshold. I think everything about the features of Datadog is amazing. Datadog provides details up to the transactions. We can look at the transaction log too for the application, which is really helpful. Datadog has impacted our organization positively since we were previously using AppDynamics and then we switched to Datadog. It has improved a lot in our alerting and monitoring in the infrastructure space and application space. We can monitor business transactions and take proactive action. It is really great to take actions on the issues before an end user reports it, which is a great advantage for us.
Antonio Scola - PeerSpot reviewer
Offers reliable security support and encourages a safe migration to cloud environments while there is room for better reseller collaboration
I really don't know to tell the truth because we sell many solutions and don't sell exclusively Tenable, so I'm not in a condition to give a precise definition of what could be improved. My perception is this: when customer A needs Tenable Cloud Security, we introduce and demonstrate it. They POC, they appreciate it. The solution serves in such use cases ABC. I am very pragmatic and straightforward - as long as they use or want the solution, I am interested. If they don't, my question is what are the main objections? They may discuss pricing, or they may say they thought the solution had certain technical capabilities that they could not find.
