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.

A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product's most valuable features are ease of installation, management, and reporting. It has an efficient ability to set thresholds for alerts, as well."
"The solution's stability has never been a problem. Stability-wise, I rate the solution a nine to ten out of ten."
"The effectiveness of filters is pivotal for optimizing the search process and extracting the specific information we need from the extensive log data."
"We are using Grafana Loki as a database for real-time metrics."
"Loki also utilizes the same service discovery mechanism as used by Prometheus. So, whatever labeled metadata you see in Prometheus, you have the exact same metadata in the Loki system. Given this level of intricacy and the attempt to address these challenges, I firmly believe that Loki deserves praise for the work."
"Different types of integrations with various sources are the most helpful and useful features of Grafana Loki that I found for myself."
"The most valuable feature of the solution is the tool's GUI. The solution's GUI is very user-friendly."
"There are new features like that pilot code and things like that for profiling."
"It gives the ability to investigate into network traffic in the Net and the organization what we couldn't do before."
"The most valuable feature is the hunting ability to work in a CERT."
"Technical support is very good; they try to resolve issues with the proper SLAs which are defined by them and they understand the client's requirements as well as the client's infrastructure in a better manner."
"NetWitness can be highly beneficial for incident detection and response."
"NetWitness Platform is valuable for creating rules that the solution must detect."
"It gives customers visibility about their most important servers and devices."
"Offers a good wireless feature."
"Once it is deployed and you are used to it, you can do whatever you want."
 

Cons

"The product must improve its UI."
"The correlation of requests is not simple in Grafana Loki and can be improved."
"My main concern is the recommended production-grade setup. They suggest using tools like Tanka or Jsonnet. They should simplify the process to increase adoption."
"I do not see any areas for improvement at the moment."
"In Grafana Loki, the creation of metrics is not so easy, making it an area that could be made easier."
"The platform's stability needs improvement."
"Improvements could be made in the enablement of the product, addressing the complexity of implementing these tools."
"The Docker container partition feature needs improvement as they do not reuse the space and goes into a pending state."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"The user interface is a little bit difficult for new users and it needs to be improved."
"Cross Platform Integration could be improved."
"We encountered stability issues in the earlier versions, and much fewer in the newer versions."
"Security needs improvement. We would still like to know how the traffic is entering the organization."
"Advance monitoring and alerting feature is not stable (Event Stream Analysis)."
"If we have the ability to run a dynamic analysis through malware in the same suite, it would be great to have a sandbox solution to analyze malware through dynamic analysis."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
