Room For Improvement

Datadog struggles with complex pricing, customization needs, usability, and requires improved integration, training, and cost management for large organizations.
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.
Operations Manager at a financial services firm with 1,001-5,000 employees
We want to be able to customize the cost part, and we would appreciate more granular access control.

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 but can become costly with larger infrastructures; users appreciate low setup costs and initial free hosts.
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.
Senior Performance and Architecture Analyst at a manufacturing company with 10,001+ employees
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.
Applications Web Services Technical Engineer at Ace Hardware
My experience with pricing, setup cost, and licensing is that it is really expensive.
Senior Site Reliability Engineer at a wholesaler/distributor with 5,001-10,000 employees
 

Valuable Features

Datadog excels with real-time monitoring, integrations, intuitive dashboards, and analytics, enhancing observability and operational efficiency in complex environments.

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.
Senior Site Reliability Engineer at a wholesaler/distributor with 5,001-10,000 employees
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.
Security Engineer at Invitation Homes
The automatic integration capabilities, particularly with DNS, Azure, and AWS, are extremely valuable.
Information Security Architect at WSP
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.

Featured Reviews

Dhroov Patel - PeerSpot reviewer
Site Reliability Engineer at Grainger
Has improved incident response with better root cause visibility and supports flexible on-call scheduling
Datadog needs to introduce more hard limits to cost. If we see a huge log spike, administrators should have more control over what happens to save costs. If a service starts logging extensively, I want the ability to automatically direct that log into the cheapest log bucket. This should be the case with many offerings. If we're seeing too much APM, we need to be aware of it and able to stop it rather than having administrators reach out to specific teams. Datadog has become significantly slower over the last year. They could improve performance at the risk of slowing down feature work. More resources need to go into Fleet Automation because we face many problems with things such as the Ansible role to install Datadog in non-containerized hosts. We mainly want to see performance improvements, less time spent looking at costs, the ability to trust that costs will stay reasonable, and an easier way to manage our agents. It is such a powerful tool with much potential on the horizon, but cost control, performance, and agent management need improvement. The main issues are with the administrative side rather than the actual application.

Information Security Architect at WSP
Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments
Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.
