Splunk Enterprise Security requires enhancements in visualizations, ease of use, AI integration, and improved documentation and training.
Users urge improvements in interface usability, automation, integration, support, AI capabilities, pricing, and visualization for Sumo Logic Security.
We receive logs from different types of devices and need a way to correlate them effectively.
Network and Security Architect at Deutsche Telekom
If AI-related support can suggest rules and integrate with existing security devices like MD, IPS, this SIM can create more relevant rules.
Information Security Analyst at Banglalink
IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.
Cyber Security Architects at VaporVM
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
This can lead to alerts that are collections of disjointed signals that sometimes make no sense and lack real context; this simplistic approach makes it hard to find coherent stories during investigations.
CSO at Altera
I would also appreciate the AWS automation integrations to be more secure because currently, they are using access keys, which involves a user rather than roles, which is the security best practice recommended by AWS.
Senior Security Analyst at City Electric Supply Company
The correlation rules and log mapping are not as mature compared to other SIM tools like Splunk.
SOC Analyst at a computer software company with 1,001-5,000 employees
 

Setup Cost

IBM QRadar is costly but efficient, flexible in licensing, negotiable, and ideal for large enterprises over smaller ones.
Splunk Enterprise Security is costly but valued for its extensive functionality, appealing mainly to larger enterprises with flexible licensing.
Sumo Logic Security offers mid-range pricing, balancing cost and functionality, with convenience through AWS Marketplace but increasing costs with usage.
Splunk is more expensive than IBM Security QRadar.
Cyber Security Architects at VaporVM
It was costly mainly because of the value you can get right now compared to other solutions.
CTO at Sabyk
It depends on how much you want to spend.
Strategic Account Executive at a computer software 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
This makes it more cost-effective because other solutions often include a third element in their pricing.
Deputy Country Manager at PT Securite Asia Indonesia (ABP Securite)
From one to ten, where one is cheap and ten is expensive, I would put Sumo Logic Security at a seven.
CISO at Mambu
If you go to the well-known vendors such as Azure Sentinel or other tools like Splunk, you are going to find them costly since they are well-known and they have much more integration compared to Sumo Logic Security.
Security Analyst at a tech vendor with 10,001+ employees

SOC Engineer at a outsourcing company with 10,001+ employees
This capability is useful for performance monitoring and issue identification.
Staff Performance Engineer at ServiceNow
I assess Splunk Enterprise Security's insider threat detection capabilities for helping to find unknown threats and anomalous user behavior as great.

HarshBhardiya - PeerSpot reviewer
SOC Engineer at a outsourcing company with 10,001+ employees
Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.
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.

Security insights have enabled faster incident response and streamlined cross-team collaboration
To improve Sumo Logic Security, I would appreciate the tool being easier to use from a search perspective. For example, we have a few teams that want to use the tool itself, but they are not as savvy when it comes to creating searches from the core platform. I understand that Mobot has come out and is in the works, and it really does assist non-savvy users when it comes to querying the platform. As far as that is concerned, I wish that could be improved a bit more, but I do know that that is in the works. I would add that I wish for improved documentation. For example, we are using Sumo Playbooks and automation integrations along with that, but I have found that there has been a lack of documentation, very little to none at all when it comes to that. With regards to automation integrations as well, there are very few details included in them. I would also appreciate the AWS automation integrations to be more secure because currently, they are using access keys, which involves a user rather than roles, which is the security best practice recommended by AWS. I chose eight out of ten because to make it a nine or ten, I would lean heavily on the documentation. A lot of the times when we get around to configuring things such as playbooks or trying to understand playbooks, what I found was that documentation sometimes is not up to date or documentation is lacking. There are instances also where some security best practices are not being followed. So, if we are able to set up an integration that is not only secure, following security best practices, and has complete documentation, I believe it would alleviate the issue of having to go back and forth with support to check the documentation and things of that nature. My impression of the built-in threat intelligence feature in Sumo Logic Security is that it is comprehensive, but I would say that it could do a little bit better. For example, we have the TAXI feeds, which is STIX and TAXI integrated into the core platform, but the issue I am running into is that I am able to use that feed into a CSE alert; however, I am not able to see the contents of that feed. If I integrate CISA, which we do have integrated, I cannot see what IOCs are in that feed in the core platform, and I hope that is the case because, in order for us to better tune our alerts, we need to be able to see what is in the contents of that threat intelligence feed.
