Senior Security Engineer at a university with 10,001+ employees
The second thing is that data aggregation, sampling, and reduction that we're able to do of the data, lowering our overall data volume, both traversing the network as well as what's being stored inside of our final solutions.

Sometimes by hearing the problem itself, they will know what the solution is, and they will let us know how to resolve it, and we do it immediately.
Senior Specialist at a tech vendor with 10,001+ employees
Local tech support is available, however, for more critical or technical issues, we depend on the OEM directly, especially when it comes to on-prem solutions.

There is a knowledgeable, though small, team of support engineers around the world.

Sentiment score

Fortinet FortiSIEM scales well, accommodating different business sizes but faces challenges with licensing, architecture, and configuration complexities.
The infrastructure behind Cribl Search is also scalable as it uses a CPU and just spawns horizontally more instances as it demands and requires.
Engineering Fellow at Pegasystems
Compared to other SIEM tools I use, any slight change on the operating system end impacts a lot on our SIEM tools and other things, but Cribl performs well in that regard.

Room For Improvement

Cribl needs improved performance, better Git integration, and enhanced usability to address user experience and scalability concerns.
Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.
A more stringent role-based access control feature would enhance security and allow granular control over what users can see and access.
Manager for Monitoring and Logging at Velera
When passing query logs or DNS logs, if certain malicious query patterns need to be identified or if fast-flux attacks are happening, Cribl can report that and those would definitely be a plus for them.
Product Manager at UnDisclosed
I would advise others looking to implement Cribl that if they are evolving Cribl Search, it would be very interesting to see more capability, more flexibility, and more ways to share the data similar to Splunk.
Senior Manager at Deloitte
Recently, they revised it to a subscription-based, all-inclusive license.
IT Solutions Product Manager at a computer software company with 11-50 employees
The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products.

Cribl has a feature called JSON Unroll or Unroll function that allows you to differentiate the events; each event will come ingested as a single log instead of piling it up with multiple events.
Security Engineer at Tecplix
The Cribl UI is very simple and easy to use, particularly when working with data from various sources; it makes it very easy to create pipelines, add complex logic to those pipelines, and then gives you a preview of what your data looks like before applying that pipeline and what you get after.
Senior Security Engineer at a university with 10,001+ employees
It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security.

JigarHirani - PeerSpot reviewer
Splunk Engineer at a recruiting/HR firm with 11-50 employees
Log pipelines have reduced daily data volume and now simplify traffic analysis
Overall, the pipelines and all the features are good with Cribl. The UI is good. Just sometimes, when I actually started using Cribl, I faced the issue where I was not able to connect the nodes. The pipeline is structured in a certain way, then the data will be routed to there, and something of that nature. I was very much confused about their whole products, such as Data Lake and pipelines. It's possible that at that time I didn't take any university courses, which is why I did not know much. But if they can give an intro on how we can connect nodes, or they can provide simple use cases showing what you can do with Cribl, it would help. If you just need to add the source and the destination and pre-build some proper workflow, then it will be easy for new customers to navigate through Cribl.

Comprehensive monitoring boosts security, yet incident management features need expansion
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management. Currently, to manage repetitive incidents or for remediation, I need to use a separate software called FortiSOAR. Additionally, the search functionality in FortiAI should be improved to provide more precise results, making it easier for me to understand what actions need to be taken.
