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.

Both response time and support quality need attention.
Team Lead SOC at a tech services company with 51-200 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.

Splunk Enterprise Security scales easily, efficiently managing large data volumes, though cost and setup may pose challenges.
Devo is a unified SIEM solution designed to handle growing log volumes and enterprise-scale monitoring requirements.
Cyber Security Engineer Ii (Vulnerability & Threat Management) at FICO
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
We have found no negative impact from scaling.

Sentiment score
7.6
Splunk Enterprise Security is highly stable and reliable, performing well with proper configuration and providing consistent user experience.
It is stable and reliable for our security operations.
Cyber Security Engineer Ii (Vulnerability & Threat Management) at FICO
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 Bank of America
 

Room For Improvement

Devo's Activeboards need better customization, integration, UI, and AI capabilities, while cost and usability require attention.
Splunk Enterprise Security needs UI, cost efficiency, AI integration, simpler onboarding, better support, and improved false positive management.
This is particularly evident when dealing with failed login attempts and determining true versus false positives.
Strategic Account Executive at a computer software company with 51-200 employees
UI improvements, a simplified dashboard, or an easier reporting workflow could further improve analyst productivity.
Cyber Security Engineer Ii (Vulnerability & Threat Management) at FICO
I would appreciate more third-party integrations including Fortinet and others.
Team Lead SOC at a tech services company with 51-200 employees
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

Devo offers transparent pricing per gigabyte, with potential metadata charges, including 400-day storage and additional feature benefits.
Splunk Enterprise Security is feature-rich but often expensive, favoring larger enterprises with strategic data management for cost efficiency.
The pricing of the product is reasonable if we compare it with other Gartner leading products like Splunk, LogRhythm, Microsoft Sentinel, Google SecOps.
Team Lead SOC at a tech services company with 51-200 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

Devo impresses with real-time analytics, intuitive UI, customization, advanced alerting, cloud-native architecture, and 400 days of data retention.
Splunk Enterprise Security enhances threat detection and response with AI intelligence, customizable dashboards, and scalable architecture for improved security.
When they see a spike in a line chart for a failed login, which could be a true or false attempt, they can click that spike, and a table widget on the same active board instantly populates with raw logs of data for those specific failed logins.
Strategic Account Executive at a computer software company with 51-200 employees
When the analyst uses queries to search, it pulls the data quickly, in a second, which aids us greatly with the investigation.
Cyber Security Engineer Ii (Vulnerability & Threat Management) at FICO
It utilizes 400 days of hot data, allowing queries to run very fast and yield results quicker than other tools in terms of security and SIEM capability.
Senior Cloud Engineer at a tech services company with 201-500 employees
This capability is useful for performance monitoring and issue identification.

Usama Khan - PeerSpot reviewer
Team Lead SOC at a tech services company with 51-200 employees
Advanced threat hunting has improved SOC visibility and now supports faster incident response
Devo can improve in how its connectors enhance integration with third-party tools. Devo's architecture works by having you deploy a relay server in the data center of the client side and Devo SIEM is basically on the AWS cloud. There are specific ports which are enabled on the relay server, which are 514 and 13000, 13151, 152. However, when we talk about databases and custom integrations, there are not default ports in the relay server. No default ports are defined. For JDBC drivers, the port number is 1433, but it is not in the relay server. You have to add it manually. For Oracle RDBMS, the port is 1521, and it is also not there by default. I would appreciate more third-party integrations including Fortinet and others. Machine learning models can also be improved. Playbooks in the SOAR can also be improved. Regarding playbooks for automation, we utilize playbooks for automation in SOAR for automated IOC blocking on a firewall, on a web application firewall, on DNS security, etc. The only option for us to run the playbook is to schedule the job for it. However, if I want to manually run the playbook, there is no option for doing so. This needs improvement.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
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.
