DevOps&Cloud Engineer Mentee at CertDirectory.io
We couldn't calculate what would have been the cost if they had actually gotten compromised; however, they were in the process, so every investment was returned immediately.
Business Development Manager at Axians Germany
On average, my SecOps team takes probably at least a quarter of the time, if not more, to remediate security incidents with Splunk Enterprise Security compared to our previous solution.
IT Orchestration Architect at Penn State University
 

Customer Service

Sentiment score
6.1
Azure Monitor's customer service is praised for responsiveness, especially with premium support, but can improve on general knowledge and speed.
Sentiment score
6.3
Splunk Enterprise Security is highly rated for support expertise, though some users report delays and inconsistent experiences.
However, the second-line support is good.
Snr. Infrastructure Architect (Data Centre) at LogicEra
Users end up getting no resolution from their team because they're outsourced vendors, and they don't have deeper expertise over any of the products they are referring to.
Software Engineer (DevOps/ SRE) at Sensys LLC
I would rate the support for Azure Monitor as a seven.
Cloud Solution Architect at Cloudzant
We have paid for Splunk support, and we’re not on the free tier hoping for assistance; we are a significant customer and invest a lot in this service.
Senior System Administrator at a tech services company with 5,001-10,000 employees
I have had nothing but good experiences with Splunk support, receiving timely and helpful replies.
Cyber Security Associate at SAP
We've had great customer success managers who have helped us navigate scaling from 600 gigs to 30 terabytes.
Principal Engineer at Aviatrix
 

Scalability Issues

Sentiment score
7.8
Azure Monitor provides scalable solutions for businesses, supports auto-scaling, integrates with tools, but requires careful cost management.
Sentiment score
7.4
Splunk Enterprise Security offers excellent scalability, managing large data volumes and supporting effortless growth across industries.
With APM, you can go heavy or you can go light. It just depends on what you want, what your use case is, and how reactive you want to be to system load or resilient to failure.
Consultant at a outsourcing company with 201-500 employees
Azure Monitor is very scalable; there are no issues with scalability for different kinds of businesses.
Cloud Solution Architect at Cloudzant
We currently rely on disaster recovery and backup recovery, which takes time to recover, during which you're basically blind, so I'm pushing my leadership team to switch over to a clustering environment for constant availability.
IT Security Engineer at a financial services firm with 201-500 employees
It is one of the things that separates it from other tooling, and if not, it is the most scalable solution out there.
Systems Development Engineer at a tech vendor with 10,001+ employees
They struggle a bit with pure virtual environments, but in terms of how much they can handle, it is pretty good.
CTO at a tech vendor with 10,001+ employees
 

Stability Issues

Sentiment score
8.3
Azure Monitor is highly stable and reliable, though less agile, with high user ratings and potential cost concerns.
Sentiment score
7.5
Splunk Enterprise Security is praised for stability and reliability, despite challenges with resource demands and custom configurations.
Azure Monitor is working fine, yet I face a costing issue as if there are a lot of logs collected in the workspace or in the center, it becomes very costly.
Snr. Infrastructure Architect (Data Centre) at LogicEra
They test it very thoroughly before release, and our customers have Splunk running for months without issues.
Splunk System Engineer at a non-tech company with 11-50 employees
Splunk has been very reliable and very consistent.
Principal Engineer at Aviatrix
We need more SMEs, and there is no mechanism to tell us about indexer or search head issues.
Senior Manager at a financial services firm with 10,001+ employees
 

Room For Improvement

Azure Monitor struggles with user-friendliness, integration, complexity, multi-cloud support, proactive monitoring, and requires enhanced usability and cost transparency.
Splunk Enterprise Security needs UI improvements, better integration, richer documentation, competitive pricing, and enhanced AI and threat detection.
If Azure Monitor can independently add one gigabyte, two gigabytes, or five gigabytes at least to log storage, I can fix the logs without syncing with Log Analytics Workspace and Sentinel.
Snr. Infrastructure Architect (Data Centre) at LogicEra
The cost skyrockets once you start using it, and there are complaints that the actual cost of the Kubernetes cluster was less than the cost they were incurring for Azure Monitor.
Software Engineer (DevOps/ SRE) at Sensys LLC
The challenges with Azure Monitor are that it's initially complex to set up because you need multiple components.
Cloud Solution Architect at Cloudzant
Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power.
Resident Consultant (Security Analyst) at helpag
Splunk Enterprise Security is not something that automatically picks things; you have to set up use cases, update data models, and link the right use cases to the right data models for those detections to happen.
Security & Risk Analyst at a computer software company with 1,001-5,000 employees
For any future enhancements or features, such as MLTK and SOAR platform integration, we need more visibility, training, and certification for the skilled professionals who are working.
Security Consultant at Matiq
 

Setup Cost

Azure Monitor offers cost-effective variable pricing, but careful management is essential to avoid high expenses for enterprise users.
Splunk Enterprise Security offers robust insights but can be costly for high data volumes, challenging affordability for smaller businesses.
When I export logs into the application, workspace, log analytic workspace, and into Sentinel to read reports, I need to add storage, which increases the cost.
Snr. Infrastructure Architect (Data Centre) at LogicEra
I saw clients spend two million dollars a year just feeding data into the Splunk solution.
CTO at a tech vendor with 10,001+ employees
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.
System Engineer - Security Presales at Raya Integration
I find it to be affordable, which is why every industry uses it.
Vice President Research And Development at OSINT Ambition
 

Valuable Features

Azure Monitor provides comprehensive real-time monitoring, alerting, and analytics, enhancing security and scalability for seamless infrastructure management.
Splunk Enterprise Security offers real-time threat detection, customization, and integration, enhancing security operations and data management capabilities.
The alerting features definitely help in reducing operational downtime for my customers by allowing us to get notifications in advance and take active actions.
Cloud Solution Architect at Cloudzant
I also appreciate the ability to measure feature activity, see what types of devices they are on, follow specific use cases, and measure the amount of traffic going to a particular application.
Consultant at a outsourcing company with 201-500 employees
Resource monitoring is essential.
Snr. Infrastructure Architect (Data Centre) at LogicEra
This capability is useful for performance monitoring and issue identification.

Consultant at a outsourcing company with 201-500 employees
Telemetry insights have improved how I track user behavior and application performance daily
I feel Azure Monitor does a fair job. I do feel it is not a streaming service in my opinion. There are advantages to having stream messaging and logging on that level. But for what it is, I feel it does well. My perspective is more based on an Application Insights agent running on a service or an app service and sending the telemetry via the agent, and also doing the filtering of telemetry at the agent level so you are not having a ton of telemetry. I believe Azure Monitor does pretty much the same thing. I have also used tools such as New Relic, and New Relic is a much more robust tool, but that is a different product and you are going to pay for that. It is a different offering altogether. The subscription that we had at the time allowed for a couple gigabytes of telemetry during the month, and I believe that telemetry only lives for about two months. You have to experiment with it to see how much you want to pay. I was not really involved in the pricing. It was more along the lines of we were running up against our limits in terms of the amount of free telemetry or telemetry that we get with our subscription, and so we either needed to scale back or turn specific telemetry types off or do some more sampling. It is nice that those capabilities are there so that you can reduce the amount of telemetry. I cannot really speak to pricing but I do believe that it is somewhat reasonable for Azure Monitor. New Relic is pretty expensive, I believe.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Splunk handles a high amount of data very well. We use Splunk to capture information and as an aggregator for monitoring information from different sources. Splunk is very good at alerting us if we have problems somewhere or if we are not getting the flow we expect. It is very easy to search for queries and events and then do analysis. The flexibility of the search capability is extremely valuable. Splunk works well with other solutions. It is very easy to set up and very straightforward to deploy. The more data you process with Splunk, the more expensive it gets; an improved pricing model is needed. It would be great if Splunk had more SIEM functionality with better customization and a better ticket tool. The on-premises scaling is a bit more limited than on the cloud. Splunk currently has some limited default rules and customizations. If they could concentrate more on compliance and security information, that would be an added bonus. Azure Monitor has made it significantly easier for us to monitor applications and infrastructure for possible problems. This solution offers a survey of surveillance in real time and a very helpful dashboard. Azure Monitor, which is integrated with Azure DevOps, has good load gathering and very good analytics. We get useful alerts with Azure Monitor that make recommendations about the security and the platform. There should be more specific detail about where problems lie. Azure Monitor is lacking somewhat in vulnerability assessment; this aspect could be better. Their automation also needs some improvement. From gathering metrics from more applications to getting processes quickly started when something goes down, automation should be better. Conclusion: For us, Splunk is the better solution. We use Splunk to search, monitor, analyze, and visualize machine data, which it does very well. The dashboard is very intuitive. The log collection and log management tools are very good. We find Splunk’s search capability to be very powerful and flexible. Splunk can access any kind of data and there is no limitation to the kind of structured or unstructured data you can extract. Our team also liked that Splunk offers better integration with more solutions.
