Customer Service

Sentiment score
5.0

Sentiment score
7.4
Fortinet FortiSIEM's customer service is seen as professional but has mixed reviews on response times and support accessibility.
They had extensive expertise with the product and were able to facilitate everything we needed.
If they could enhance their internal logging, we won't require Cribl support to engage.
The community, including the engineering and sales teams, is available on Slack and is very supportive.
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.
They take some time to respond because they need logs and investigations, which delays the response time.
 

Scalability Issues

Sentiment score
5.9
Cribl is highly scalable, enabling efficient workload distribution and quick deployment, appealing to businesses of all sizes.
Sentiment score
7.2
Fortinet FortiSIEM scales well, accommodating different business sizes but faces challenges with licensing, architecture, and configuration complexities.
It's an enterprise version, and we have a good amount of users using this solution.
I don't need to talk to a Cribl engineer to connect a new log source.
Cribl is quite scalable, as we could add worker nodes as our data grows.
At any point in time, when network devices increase or there is a change in the infrastructure, we can add more workers and collectors to expand our infrastructure setup.
Fortinet FortiSIEM is highly scalable.

Stability Issues

Sentiment score
6.3

Sentiment score
5.6
Fortinet FortiSIEM is reliable and stable, handling updates well, with users rating its performance highly despite occasional bugs.
I would rate the stability as ten out of ten.
If the pipeline is down and we receive an alert that it's not sending information to the log collection platform for more than one or two hours, if we receive an alert, it would be great.
Cribl is quite stable and doesn't crash; there's no unusual behavior.
It stabilizes itself in an appropriate time, so its uptime is good.
These issues may cause unusual errors and user interface issues.
Some stability issues occur, but Fortinet's technical support team provides assistance.
 

Room For Improvement

Cribl faces compatibility issues, UI limitations, and documentation inconsistencies, requiring enhancements in integration, customization, and data handling.
Fortinet FortiSIEM needs improvements in integration, user interface, support, cost, and features like AI and automated responses.
If we can have more internal logs and more debug logs to validate the error, that would be beneficial because instead of reaching out to Cribl support, we can troubleshoot and find the root cause ourselves.
In terms of large datasets—whether they originated from network inputs, virtual machines, or cloud instances—ingesting the data into the destination was relatively easy.
Since Cribl is such a large platform with numerous features, having a clear, structured approach would make it easier for me and others to understand and utilize its capabilities.
Recently, they revised it to a subscription-based, all-inclusive license.
The built-in APIs in Fortinet FortiSIEM are somewhat lacking and could be improved for better integration with external ITSM products.
Fortinet FortiSIEM should broaden its remediation part to include more features for incident management.
 

Setup Cost

Cribl offers competitive pricing valued for cost-effectiveness and scalability, though its complex credit system can cause confusion.
Fortinet FortiSIEM provides flexible pricing that can be cost-effective, but costs may increase with additional modules and scalability.
Over time, the licensing cost has increased.
Cribl is very inexpensive, with enterprise pricing around 30 cents per GB, which is really decent.
Setting it up for oneself as an enterprise-licensed product can be quite expensive.
Windows agent licenses cost around 3,000 Rupees per device per year.
The revised model is subscription-based and more flexible.
 

Valuable Features

Cribl is praised for its efficient data management, integration capabilities, user-friendly interface, and flexibility in handling large volumes.
Fortinet FortiSIEM provides automation, analytics, and integration with a user-friendly interface for efficient threat detection and network monitoring.
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.
The community on Slack is excellent for solving questions and getting ideas.
It provides extensive logging and record-keeping for internal networks, cloud applications, and services as well as perimeter physical network security.
I find the real-time monitoring and correlation capabilities effective for security alerts.

Helps reduce log ingestion cost by dropping unnecessary events and customizing pipelines
The best feature in Cribl, when getting logs from some custom application, is the ability to break up logs that pile up together and come as one event. 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. This is critical as this generally happens in CrowdStrike. This feature helps us significantly. When the ingestion is high from unwanted logs, logs not related to security purposes can be dropped by writing the parser function. By dropping events that are not required for security purpose monitoring, we can reduce the ingestion, which drastically reduces the cost as well. Cribl gives another option where I can store some logs, and when needed, I can pick them up from there. The interface is very handy and not very complicated, yet there are many functions you can perform. You can play around with numerous functions, parse there, and add UDMs to SecOps, which makes it really easy. To simplify the pipeline, when we go to the pipelines, there are vast options. We can make it specific requirements based on the customers. I would prefer a customized or simplified version. Cribl is a very good platform to work with, with lots of features that other platforms don't provide.
