Security Officer at JSC "Moldtelecom" S.A.
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
Senior Manager at Bank of America
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 centralized logs where one can find bugs quicker and find the line of code that is a problem has made us more efficient."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"I know that there are other similar tools available, but I enjoy using Graylog the most."
"We run a containerized microservices environment, and being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"Graylog is very handy."
"The solution's most valuable feature is its new interface."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"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 initial setup is straightforward"
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"It is stable."
"I have made use of technical support and am certainly very satisfied with them."
"What I found most useful in ManageEngine EventLog Analyzer is its integration with other ManageEngine applications; it seamlessly integrates throughout the ManageEngine suite, and that's beneficial, and I also like that the solution has chain management capabilities, it has a modular approach, and it's easy to reach the support team."
"ManageEngine EventLog Analyzer is useful for log and alert correlation and is a full-function SIEM solution."
"The most valuable features of ManageEngine EventLog Analyzer are the number of capabilities, file integration monitoring, web server log collection, and alert configuration."
"The best features I've experienced over the past six years with Splunk Enterprise Security are the ability to create use cases and the flexibility to customize searches and use cases based on our specific requirements."
"I really appreciate the all-integrated SIEM feature of Splunk Enterprise Security, which serves as a one-stop shop to get all security tasks done."
"It's standardized and easy to use, so you don't have to have a lot of top-tier analysts to do the same job."
"Splunk Enterprise Security has saved us time and money by making it easier to investigate events."
"Splunk Enterprise Security positively impacts our organization and clients mainly through early detections in the security landscape, allowing us to detect vulnerabilities and intrusions much earlier than previously undetected issues."
"The features of Splunk Enterprise Security that I find most valuable include Mission Control, which I really appreciate, the way accelerated data functions, making it really fast to see, the integration with SOAR, which is something really cool and integrates with automated processes, and the way to ingest threat intelligence feeds, which is an amazing feature as well."
"It helps us to detect viruses and security events from our network."
"The solution's most valuable feature is the incident review, which gives a good overview of our security incidents."
 

Cons

"The documentation for Graylog Enterprise can be improved, as this has been a pain point."
"I would like to see some kind of visualization included in Graylog. The report is plain, they could be improved."
"I would rate them as a two out of 10. You are on your own without an enterprise license."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"There should be some user groups and an auto sign-in feature.​"
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"The technical support is a weak point in this product. It's not so easy to contact them and they don't answer immediately."
"For Python developers, it would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"The first tier of customer service and support is not great, and additional upgrades could be included."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"It may not be as easy to use as Splunk."
"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 isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"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."
"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."
"Our two main complaints are about the difficulty of the initial setup and the licensing model."
"The presence of multiple layers creates a significant challenge for monitoring across cloud environments."
"It could be more user friendly, in terms of the end-user experience."
"The product was designed for security and IT with business intelligence needs, such as PDF exporting, but this has not been the highest priority. While the functionality is there, it could be developed more."
"Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard."
"Splunk has a steeper learning curve, making it feel less user-friendly."
"Queries are not always as easy or straightforward as they might be, so it can be difficult to figure out what you need to look for."
"Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."
 

Pricing and Cost Advice

"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."
"I use the free version of Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"Having paid official support is wise for projects."
"We're using the Community edition."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"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."
"There is a yearly subscription for the solution."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"Splunk Enterprise Security's pricing is competitive."
"It is expensive. I work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
"The licensing is good, but the pricing absolutely needs some work. It is very high."
"Splunk can be expensive, as its licensing is based on the daily data ingestion volume."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"The pricing can be better. We are already considering Elastic because Splunk is too expensive. You have to pay based on per-day ingestion. There should be a more flexible model for the use cases where one day you have a huge amount, and on other days, it is quite less."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more."
