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.
Senior Software Engineer at a retailer with 1,001-5,000 employees

Cribl is praised for reliability and robust performance, despite occasional bugs and infrequent resource consumption and latency issues.
Sentiment score
7.7

Migrating from those SC4S servers to Cribl worker nodes has truly been a game-changer.
Sr. Lead Security Engineer at a tech vendor with 10,001+ employees
Regarding scalability, we started with zero servers and have around 285 servers now.
Senior Specialist at LTIMindtree

Security Delivery Senior Analyst at Accenture
 

Room For Improvement

Cribl encounters scalability, performance, and integration challenges, with users citing complexity, documentation issues, and steep learning curves.
Grafana Loki needs improved usability, integration, and features like customizable reports, better UI, security, and machine learning analytics.
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
Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools.
Regional Associate & Engineer at a outsourcing company with 1,001-5,000 employees
It would be beneficial if Loki could directly access Windows Server logs or events directly from the servers.
Manager Director at Earth
 

Setup Cost

Cribl pricing is competitive, offering value for large data volumes with straightforward setup and maintenance appreciated by enterprises.
Grafana Loki's open-source and affordable cloud options make it appealing to cost-conscious enterprises seeking scalable logging solutions.
Over time, the licensing cost has increased.

Splunk is more expensive, and Cribl appears to be more affordable.
Principal at a hospitality company with 10,001+ employees
The cloud version is competitively priced compared to other market solutions.

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 a clear picture about the state of the system and gives needed information for taking action and quickly fixing problems.

Featured Reviews

Aman Verma - PeerSpot reviewer
Senior Software Engineer at a retailer with 1,001-5,000 employees
Has helped reduce daily log volume significantly and streamline data routing across multiple destinations
Regarding complexity, as I mentioned before, Cribl is very simple to use. When I started 2.5 years ago, it was very easy to learn. I learned Cribl within a week, and even though I was a fresher at the time, it was easy to understand and not complex enough that someone would need to spend money on labs. It's not that complex to learn. Regarding cost efficiency, it's very good because nowadays the SIEM tools we use are too expensive on license, and SIEM tools base their license on how many logs get ingested. The unwanted logs, particularly firewall logs, represent a significant portion of unnecessary ingestion. Cribl saves our license by filtering out half of the firewall logs that are unwanted. Our main purpose for using Cribl is to save our license and save money. Currently, everyone is moving toward AI agents. We currently use regex, and AI agents could help us create those regex patterns to drop events or add raw data to events. Currently, we sit down, review the logs, and create regex patterns manually, which can be time-consuming. An AI agent could reduce this time. I read some articles indicating that Cribl Cloud has started using AI and considering MCPs and model context, but I'm not certain how far along they are. If Cribl asked me what they could improve, that would be my suggestion. The support is very good, and I had a few issues with Cribl where I raised support cases and received good responses, which is better than the quick response I didn't get from other SIEM tools and vendor tools I use. Compared to other SIEM tools, Cribl is cheaper than Splunk and DataDogs. However, it's still a bit expensive from my point of view, though I won't call it expensive. Overall, I think 99% of companies use Cribl before their SIEM tools, and compared to SIEM tools, Cribl is cheaper. Companies can use any SIEM tool such as Google, Splunk, or Cisco, and Cribl is cheaper than those SIEM tools. They might have a slight chance to reduce costs further, but I'm not the correct person to evaluate that since I'm more focused on the operational side. Regarding training, it was quite easy to grasp. It took me almost a week to understand the basic functionalities and what Cribl does. Getting more expertise took additional time, but basic functionalities and understanding what Cribl does took around four to five days. One point I want to mention is that Cribl could improve their labs or training materials in their Cribl Cloud or whatever portal they have.

Offers cost-effective log management with strong correlation features across observability tools
Grafana Loki's open-source capability is a significant benefit. Grafana has invested in making their enterprise tools competitive with other APM tools, facilitating cross-correlation with Mimir and Tempo for metrics and tracing. The tool offers good search functionality, and its on-premises capability is advantageous. The indexing performance is strong, making it a robust log management tool. Grafana Loki is notably cost-effective.
