Log analysis has become clearer and faster but visualization and extensibility still need work
The problem was with the complexity and the cost to add extensions. We found this very expensive to buy another version with additional features. I think that Graylog Enterprise does not have customizable dashboards. I did not see them in Graylog Enterprise because most of the time we used the open source free version, which is limited. I think Graylog Enterprise should improve some things that they have in the paid version and perhaps provide users with a menu that gives examples of parsing logs and draws graphics so that people do not need to improve another system such as Grafana. This would be interesting. When it comes to functionalities, I found the log management in Graylog Enterprise acceptable. It is very simple to use and to collect logs. It has support for different protocols and different ports, and the sidecar is easy to use. However, in visualization, I think it needs to be much better.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"The Graylog features that have proven to be most beneficial for our data analysis in particular are that we tend to use it as a big data store, so we have the correlation rules that, if something matches under certain conditions, it raises an alarm."
"Troubleshooting is straightforward with Graylog Enterprise."
"The product is scalable. The solution is stable."
"We have scaled from a single machine installation (a VM with a Graylog + ES + MongoDB) to (2 Graylog + 2 ES + 3 MongoDB). This was done smoothly with a minimal impact on logging."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"The log management has helped to improve my organization."
"The user interface is very good."
"The initial setup is straightforward"
"The tool's reports show activities."
"It is stable."
"I have made use of technical support and am certainly very satisfied with them."
"The support system is very good."
"It's one of the easiest products. It's very simple to use."
"The reporting aspect is good and it does what I need it to do."
"Visualizations are the best way to understand deviation techniques from the norm."
"Splunk Enterprise Security offers valuable features like seamless integration and a SQL-standard Structured Query Language for easy searching."
"If properly built, I'm very impressed with the stability of Splunk ES."
"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."
"The features I appreciate the most in Splunk Enterprise Security are the scheduled alerts and the search function."
"Splunk's interface is user-friendly, and it has apps and add-ons for most applications. We can easily normalize the data to make it readable and understand the logs. We easily get all the field extractions and enrichment done by using the apps and add-ons. This helps us understand the application logs because the raw data is useless unless we extract some useful information from it. These add-ons make it so much easier."
"The feature I appreciate the most about Splunk Enterprise Security is the CIM data model, which allows users to bring in data from different technologies, such as firewalls, endpoints, and perimeter DMZs, enabling every device to pump data into Splunk Enterprise Security, with the data model normalizing all the data and placing it in a common plane."
 

Cons

"Graylog can improve the index rotation as it's quite a complex solution."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"Graylog could improve the process of creating rules. We have to create them manually by doing parses and applying them. Other SIEM solutions have basic rules and you can create and get more events of interest."
"I would like to see a date and time in the Graylog Grok patterns so that I can save time when searching for a log. I like how the streams and the search query work, but adding a date and time will allow me to pull out a log in a milli-second."
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"Lacks sufficient documentation."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"The scalability is limited."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"There's a lot to improve in terms of connectivity. Currently, we're utilizing it across various infrastructures and environments, including others' cloud. However, connecting it to our infrastructure and integrating it with some of our SMAX solutions poses difficulties."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"The first tier of customer service and support is not great."
"The solution should improve on its log capturing capabilities."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"Having analysts put their notes directly within the investigation feature in the incident review would be beneficial."
"The price has room for improvement."
"The search could be improved. Now, it is a bit difficult to write search queries because they become quite long, then maintaining those long search queries is a quite challenging."
"The configuration could be better."
"It's costly."
"The administration of the cluster and app deployment to indexers or search heads can be done only using ssh access and command line, there is no GUI tools for that."
"More training on PetaData using artificial intelligence techniques to identify the events which are not normal and exceptions that would help the organization identify threats and malware on the go with results."
"Sometimes, the data does not match what we're looking for, or the tool contains incorrect data."

"I use the free version of Graylog."

"We are using the free version of the product. However, the paid version is expensive."

"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
