Splunk Enterprise Security improves efficiency and threat detection, reducing time and costs despite its expense for larger organizations.
In a world surrounded by data, tools that allow navigation of large data volumes ensure decisions are data-driven.
Corporate HR Financial Controller at STMicroelectronics Holding
Power BI is easy to deploy within an hour, providing robust security against data leaks.
Senior Manager, Strategy & Consulting at Viacom18 Media Pvt Ltd
The documentation for Splunk Enterprise Security is outstanding. It is well-organized and easy to access.
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
6.6
Microsoft Power BI's support is praised for resources and community but needs improvement in response time for complex queries.
Sentiment score
6.2
Splunk Enterprise Security is highly rated for support expertise, though some users report delays and inconsistent experiences.
The significant drawback I notice is that Microsoft's size makes it hard to get specific change requests addressed unless they involve a bug.
Corporate HR Financial Controller at STMicroelectronics Holding
We have a partnership with Microsoft, involving multiple weekly calls with dedicated personnel to ensure our satisfaction.
Executive Director, Decision Support at Community Health Network
The support is good because there is also a community available.
Business Development Director at a tech consulting company with 201-500 employees
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
6.9
Microsoft Power BI offers scalable solutions for various enterprises, excelling in integration yet facing challenges with large data volumes.
Sentiment score
7.3
Splunk Enterprise Security offers excellent scalability, managing large data volumes and supporting effortless growth across industries.
You expect only a small percentage of users concurrently, but beyond a thousand concurrent users, it becomes difficult to manage.
Senior Manager, Strategy & Consulting at Viacom18 Media Pvt Ltd
With increasing AI capabilities, architectural developments within Microsoft, and tools like Fabric, I expect Power BI to scale accordingly.
Executive Director, Decision Support at Community Health Network
As more data is processed, performance issues may arise.
Product Owner at ABN AMRO Bank N.V.
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

In terms of stability, there's no data loss or leakage, and precautions are well-managed by Microsoft.
Senior Manager, Strategy & Consulting at Viacom18 Media Pvt Ltd
We typically do not have problems with end-user tools like Excel and Power BI.
Executive Director, Decision Support at Community Health Network
It is very stable for small data, but with big data, there are performance challenges.

They test it very thoroughly before release, and our customers have Splunk running for months without issues.

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

Microsoft Power BI needs better integration, flexible pricing, enhanced features, improved data handling, and seamless compatibility with various platforms.
Splunk Enterprise Security needs UI improvements, better integration, richer documentation, competitive pricing, and enhanced AI and threat detection.
This makes Power BI difficult to manage as loading times can reach one or two minutes, which is problematic today.
Senior Manager, Strategy & Consulting at Viacom18 Media Pvt Ltd
Access was more logical in how it distinguished between data and its formatting.
Corporate HR Financial Controller at STMicroelectronics Holding
Microsoft updates Power BI monthly based on user community feedback.
Executive Director, Decision Support at Community Health Network
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

Microsoft Power BI is competitively priced, offering flexible licensing with free to premium options, viewed favorably against competitors.
Splunk Enterprise Security offers robust insights but can be costly for high data volumes, challenging affordability for smaller businesses.
I found the setup cost to be expensive
Responsable du département Projets et Applications at CHD Vendée
Power BI isn't very cheap, however, it is economical compared to other solutions available.
Senior Manager, Strategy & Consulting at Viacom18 Media Pvt Ltd
The pricing for Microsoft Power BI is low, which is a good selling point.
Business Development Director at a tech consulting company with 201-500 employees
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

Microsoft Power BI provides seamless integration, intuitive visualizations, and real-time processing, ideal for organizations' efficient data analysis needs.
Splunk Enterprise Security offers real-time threat detection, customization, and integration, enhancing security operations and data management capabilities.
In today's data-driven environment, these tools are of substantial value, particularly for large enterprises with numerous processes that require extensive data analysis.
Corporate HR Financial Controller at STMicroelectronics Holding
Within the organization, Microsoft Power BI is used to create dashboards and gain insights into data, enhancing data-driven decision-making.
Product Owner at ABN AMRO Bank N.V.
To reduce the need for highly skilled personnel, we can engage someone who is just familiar and has a basic understanding of Microsoft Power BI, while AI can handle the major tasks through either agent AI or requirement analysis.

Featured Reviews

Shoury Priyanshu - PeerSpot reviewer
Senior Manager, Strategy & Consulting at Viacom18 Media Pvt Ltd
Facilitates seamless data aggregation with some outdated visual elements hindering user appeal
Real-time data integration is an area for improvement. Although I've worked on several solutions involving real-time integration, it's not very user-friendly and often lags, especially with over a million data rows. This makes Power BI difficult to manage as loading times can reach one or two minutes, which is problematic today. There are challenges with scalability, requiring multiple pages in dashboards to manage these issues. Visualization could be improved as it appears outdated. Users, especially newcomers, find it unappealing and not user-friendly.
reviewer1469784 - PeerSpot reviewer
Senior Manager at a financial services firm with 10,001+ employees
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.
