Featured Reviews

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.
Ondrej Kováč - PeerSpot reviewer
Has vulnerability detection, software composition analysis and asset management features
Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product. Another area needing improvement is the implementation complexity, especially in multi-cloud environments. Tenable Cloud Security's features mean there's a steep learning curve, which can consume significant time and resources to utilize the platform's potential and fully see immediate benefits. It's similar to AI in that you must spend time fine-tuning and training before it truly helps.

Quotes from Members

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

Pros

"We have way more observability than what we had before - on the application and the overall system."
"The observability pipelines are the most valuable aspect of the solution."
"The server monitoring, service monitoring, and user session monitoring are extremely helpful, as they allow us to be alerted ahead of time of issues that users might experience."
"The product has offered increased visibility via logging APM, metrics, RUM, etc."
"The solution's SaaS model is easy to manage and works well in single- or multi-cloud environments."
"Real user monitoring gives us invaluable insights into actual user experiences, helping us prioritize improvements where they matter most."
"APM is great and has provided low-effort out-of-the-box observability for various services."
"We've been able to glean from the monitors what servers are down, and can alert the team in Slack."
"If you have multi-cloud tenancy using AWS and Azure, you can have a single dashboard where you can onboard all the cloud infrastructure and have visibility into it."
"The product's deployment phase is easy."
"Ermetic can provide super visibility for our cloud environment (we are using AWS)."
"The tool alerts us on depreciating performance or deficiencies of our web application. It helps us react on time."
"Scanning and reporting are the most valuable features of Tenable Cloud Security"
"The solution’s vulnerability management feature has helped us identify and mitigate risks well."
"Tenable Cloud Security excels in vulnerability detection, one of its strongest features. Another valuable feature is software composition analysis, which highlights and automates the detection of security flaws. Additionally, their knowledge base is excellent; if anything goes wrong, they provide clear guidance on what needs to be done to address specific vulnerabilities."
"The product's visibility and remediation work fine for me."
 

Cons

"Datadog has a lot of documentation, but a lot of that documentation assumes you know how the service works, which can lead to confusion."
"I think better access to their engineers when we have a problem could be better."
"The cost does add up quickly, so it can be some effort to justify the necessary outlay to those paying the bills."
"The ease of implementation needs improvement."
"We did have an issue where a synthetic test was set up before the holiday break, and we were quickly charged a great amount. Our team worked with Datadog, and they were able to help us out since it was inadvertent on our end and was a user error."
"While the documentation is very good, there are areas that need a lot of focus to pick up on the key details."
"The logging could be improved in the future."
"While I like the ease of use, when compared with Tenable Nessus they could still improve their usability."
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."
"I didn't find anything that wasn't useful or needed to be added."
"The product must provide more features."
"There is a need for the support team to improve their response time since it is one of the areas where the product's technical team has certain shortcomings."
"Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product."
"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."
"I have faced several bug incidents with the solution"
 

Pricing and Cost Advice

"Pricing seemed easy until the bill came in and some things were not accounted for."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"The solution is fairly priced but history and log storage can get costly depending on your needs."
"It is easy to run up a large bill, so become familiar with the cost of each piece of your bill and use the metrics they supply to estimate and monitor your bill."
"This solution is budget friendly."
"The price is better than some competing products."
"Our licensing fees are paid on a monthly basis."
"If you do your homework, you'll find that if you're really concerned with cost, it's good."
"The tool's price is good compared to other brands. The tool's subscription is for a year."
"There is a need to opt for a subscription-based pricing model to use Tenable Cloud Security. I rate the product price an eight on a scale of one to ten, where one is low price and ten is high price."
"The tool's pricing is fair."
