Room For Improvement

Datadog struggles with performance, usability, and cost issues, requiring improvements in integration, documentation, and user interface.
Tenable Cloud Security needs faster operations, improved support, detailed reporting, AI integration, and easier multi-cloud implementation.
The documentation is adequate, but team members coming into a project could benefit from more guided, interactive tutorials, ideally leveraging real-world data.
There should be a clearer view of the expenses.
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's pricing model is flexible yet can be costly, requiring careful planning to optimize its comprehensive features and avoid surprises.
Users find Tenable Cloud Security's subscription model reasonably priced and well-suited for enterprises, offering good value compared to competitors.
The setup cost for Datadog is more than $100.
 

Valuable Features

Datadog excels in integration, monitoring, and data visualization, enhancing system reliability and efficiency with seamless AWS synchronization.
Tenable Cloud Security offers comprehensive vulnerability detection, deep cloud analysis, IAM features, and multi-cloud integration into a single dashboard.
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.
The technology itself is generally very useful.
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.

Kevin Palmer - PeerSpot reviewer
Useful log aggregation and management with helpful metrics aggregation
Datadog provides us value in three major ways: First, Datadog provides best-in-class functionality in many, if not all, of the products to which we subscribe (infrastructure, APM, log management, serverless, synthetics, real user monitoring, DB monitoring). In my experience with other tools that provide similar functionality, Datadog provides the largest feature set with the most flexibility and the best performance. Second, Datadog allows us to access all of those services in one place. Having to learn and manage only one tool for all of those purposes is a major benefit. Third, Datadog provides significant connectivity between those services so that we can view, summarize, organize, translate and correlate our data with maximum effect. Not needing to manually integrate them to draw lines between those pieces of information is a huge time savings 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.
