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.

Scalability Issues

Sentiment score
6.3
OpenText Behavioral Signals faces scalability challenges, while technologies like ArcSight Intelligence excel, prompting consideration of alternatives like Splunk.
Sentiment score
7.3
Splunk Enterprise Security offers scalable architecture, supporting diverse environments and data volumes, though costs increase with large data growth.
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

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

OpenText and ArcSight require updates for usability, scalability, and pricing to compete with QRadar and Splunk effectively.
Splunk Enterprise Security needs UI improvements, better training, cost reductions, enhanced integrations, optimized analytics, and increased automation.
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

CTO at a tech vendor with 10,001+ employees
The platform requires significant financial investment and resources, making it expensive despite its comprehensive features.

Featured Reviews

Pravir KumarSinha - PeerSpot reviewer
Information Security at Synechron
Has essential threat detection capabilities, but the features for intelligence need enhancement
We integrated this tool with our security infrastructure. We installed it on a Linux server, where we have a Logger and ESM installed. With the Linux server as the hub, we manage all the configurations and rules, including those for email triggers. The logs are routed through a connector to the Logger, allowing us to monitor our infrastructure effectively. The platform helps us improve threat detection capabilities. I recommend it to others and rate it a seven out of ten.
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.
