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.

Room For Improvement

Alluvio Aternity requires simpler interfaces, improved custom reporting, flexible licensing, better integrations, and enhanced data visualization features.
Cribl faces performance and cost challenges with large data, user interface issues, and requires better documentation, training, and automation.
The integration of AI agents could enhance these tools further, replacing traditional agents and plugins.
Consultant at a energy/utilities company with 10,001+ employees
Riverbed can make Alluvio Aternity better by having the same Aternity agent help in security, such as antivirus or EDR, which would be useful, allowing customers to avoid having multiple agents installed on their endpoint machines.
Technical Lead at M.TECH Solutions India Pvt. Ltd.
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
 

Setup Cost

Alluvio Aternity offers valuable analytics but can be costly; negotiation, setup and training influence overall investment significantly.
Cribl's pricing is seen as cost-effective for its scalability and features, despite potential high costs for smaller companies.
Riverbed is costly in the Indian market
Technical Lead at M.TECH Solutions India Pvt. Ltd.
Over time, the licensing cost has increased.

The reporting part of Alluvio Aternity is good; it is granular, user-friendly, and easy to use.
Technical Lead at M.TECH Solutions India Pvt. Ltd.
The data reduction and preprocessing capabilities make Cribl really unique.

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.

Akhilesh Mishra - PeerSpot reviewer
Technical Lead at M.TECH Solutions India Pvt. Ltd.
Monitoring end-user activity has improved visibility into device and application performance
In my opinion, Riverbed can make Alluvio Aternity better by having the same Aternity agent help in security, such as antivirus or EDR, which would be useful, allowing customers to avoid having multiple agents installed on their endpoint machines. Deploying multiple agents can use the processor and utilize memory, so it's better to go with one agent. If one agent can do end-user activity monitoring and act as an EDR, then it would be better for the end-user, allowing easy avoidance of installing multiple agents on their machines.
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.
