Room For Improvement

Datadog needs better alert management, cost control, data representation, API consistency, integration, security, automation, navigation, and educational resources.
SentinelOne Singularity AI SIEM requires improvements in performance, customization, integrations, automation, pricing, and clearer AI insights.
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.
Service Manager at PwC
Having more transparent and granular cost control features would make it easier to manage usage.
Network Security Consultant at NTT DATA
The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things.
Associate Vice President at Novac Technology Solutions
The interface flickers frequently, and sometimes it does not load properly.
IT Security Analyst at a tech consulting company with 11-50 employees
Whenever OT security comes into the picture, the customers do not allow us to integrate their OT devices on a cloud. It should be available on-premises because the OT SIEM market, in the India market for instance, is something around a four to eight billion dollar market.
Vice President Cyber Security Practice Head at orbit techsol w pvt.ltd
 

Setup Cost

Datadog offers scalable, usage-based pricing but requires careful monitoring to manage escalating costs and optimize feature utilization.
SentinelOne Singularity AI SIEM offers a value-driven package with bundled services; its advanced capabilities justify slightly higher costs.
The setup cost for Datadog is more than $100.
Senior Performance and Architecture Analyst at a manufacturing company with 10,001+ employees
Pricing is mainly based on data ingestion, such as logs, metrics, and traces, and it can increase quickly if everything is enabled by default.
Cyber Security Consultant at HR Software Solution
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
I find SentinelOne's pricing to be reasonable and competitive.
Information Security Principal at a venture capital & private equity firm with 1,001-5,000 employees
Features such as centralized log management, AI-driven analytics, automated workflow, and integrated security options can reduce operational overhead and improve SOC efficiency, which helps justify the investment.

Compared to another SIEM tool's pricing, the pricing is the best, from my side.

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.
Dev Reshwal - PeerSpot reviewer
Technical Support Executive at Softcell Technologies Limited
Automation has reduced workload and real-time monitoring provides faster incident response
SentinelOne Singularity AI SIEM is the best, but sometimes the dashboards are a little simple compared to other tools. The custom dashboard is not available in their features. Therefore, I would suggest adding the custom dashboard for any of our requirements. The AI-driven analytics from SentinelOne Singularity AI SIEM has not affected our ability to reduce false positives. SentinelOne Singularity AI SIEM has affected my SOC's efficiency in investigating alerts and responding to incidents. If we receive any alerts, we can observe what activity is being done. We can see if it is malicious or something suspicious, or a true positive. We can analyze the path, the hash, and whether the signature is verified or not. We can see if it is an alert triggered by any engine. We can see the source of this. We will do that type of analysis and raise it to the client side. Also, if I identify anything suspicious or malicious in the alert, I will forcefully kill and quarantine it immediately.
