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.
Sathis-Kumar - PeerSpot reviewer

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

"Feature-wise or from the end user perspective, Graylog is just great."
"It is easier to find some issues, and if I find some issues, then it is easier to resolve them."
"The ability to write custom alerts is key to information security and compliance."
"The product is scalable. The solution is stable."
"I like the simplicity of the solution, the fact that it's open source and user friendly."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"The initial setup is straightforward"
"Our primary use case for this solution is detecting issues to provide customers with information."
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"The initial setup was very simple and straightforward, according to our security team."
"We use the solution because it is granular."
"The tool's reports show activities."
"ManageEngine EventLog Analyzer is useful for log and alert correlation and is a full-function SIEM solution."
"I find it beneficial that Splunk Enterprise Security easily integrates with other tools. Due to its excellent API capabilities, it facilitates connections with various cybersecurity tools."
"The product provides visibility and enables us to correlate data and generate alerts."
"I like Splunk's data aggregation and search capabilities."
"Splunk can be scaled to any environment; the way it's designed, it's cloud-ready, and it has a lot of performance, in-built indexing, and performance tuning options, and Splunk is easily scalable."
"Generally speaking, their support is pretty good and their response time is pretty good."
"Searches logs from all devices and gives valuable information to the organisation, so it can drill down on all reports and security threats."
"Splunk Enterprise Security is a huge value-add to us because I can confirm that our security team treats it as a normal component of their daily operations."
"From a visibility perspective, the solution has significantly improved our organization by providing a single platform to visualize our entire IT landscape."
 

Cons

"The initial setup was really complex because I did it myself."
"We ran into problems with Elasticsearch throwing a circuit-breaking exception due to field data size being too large. It turned out that the heap size directly impacted this size in a high-throughput environment, causing unexplained instability in Graylog. We were able to troubleshoot on the Elasticsearch size, but we should have been able to reference some minimum requirements for Graylog to know that our settings weren't sufficient."
"Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous."
"Dashboards, stream alerts and parsing could be improved."
"Graylog can improve the index rotation as it's quite a complex solution."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"There should be some user groups and an auto sign-in feature.​"
"If you have a whole team trying to fix the Graylog instance for two days, that's a bit too much."
"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
"It may not be as easy to use as Splunk."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"The product does not have certain advantages, especially the correlation tools. It was not working as per our expectations."
"The scalability is limited."
"I would like to see more detailed reports."
"Support could improve to make the solution better."
"The first tier of customer service and support is not great, and additional upgrades could be included."
"While Splunk offers SOAR as a separate product, integrating it into the next version of Splunk Enterprise Security as a unified solution would be beneficial."
"Splunk Enterprise Security can be improved mainly from the user interface regarding the visualizations. They are working on it, yet there are only five to ten very basic visualizations."
"I have not seen ROI with Splunk Enterprise Security."
"Most of my interaction is with the user community, which is how Splunk wants it. When I need help, that community is very hit or miss."
"It requires a significant amount of relatively complex architecture once you push past the single server instance."
"Splunk does not build apps. They only go back and validate the apps that somebody has already built. They should have remote consulting support. They have a wonderful solution. They have 24/7 security. Nobody needs to depend on any third party and will therefore just buy Splunk on the cloud."
"The solution is expensive."
"You do need a lot of training and certification with this product."
 

Pricing and Cost Advice

"It's an open-source solution that can be used free of charge."
"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"We're using the Community edition."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"It's open source and free. They have a paid version, but we never looked into that because we never needed the features of the paid version."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"There is a yearly subscription for the solution."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"It's a yearly subscription."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
"The price of Splunk is reasonable."
"Splunk Enterprise Security is expensive."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
"It's definitely worth it."
"Splunk Enterprise Security is affordable."
