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

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

"Graylog Enterprise positively impacts the organization by helping the team and analysts investigate incidents faster since logs from servers, endpoints, cloud, and firewalls are available in one place."
"Open source and user friendly."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Real-time UDP/GELF logging and full text-based searching."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"With Graylog Enterprise, monitoring improved by up to 80 percent because of having all the logs centralized."
"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."
"Troubleshooting is straightforward with Graylog Enterprise."
"Our primary use case for this solution is detecting issues to provide customers with information."
"The initial setup is straightforward"
"The tool's reports show activities."
"We use the solution because it is granular."
"The most valuable features of ManageEngine EventLog Analyzer are the number of capabilities, file integration monitoring, web server log collection, and alert configuration."
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"ManageEngine EventLog Analyzer was a lower-cost alternative, and it was easier to install and manage."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"I'm not sure about the money but in saved time and a new kind of visibility for the system/business process this product has been revolutionary in the working environment."
"The ability to manage large amounts of generated data and to protect all devices from unauthorized use are the most valuable features."
"Ease of correlation, creating correlation searches are easy and you can combine multiple sources with little effort"
"Immensely, I cannot stress enough the positive impact this has had on our security team."
"It is definitely the best tool I've ever used, but nothing is perfect."
"Splunk Enterprise Security has positively impacted my organization since everything we do in some form relates back to Splunk, and as a detection engineer, my responsibility is to make sure we're collecting the right information and filtering out the wrong."
"The Splunk Enterprise Security's threat-hunting capabilities have been particularly useful in later releases."
"We are satisfied with Splunk Enterprise Security, and it comes with a wide number of out-of-the-box applications which do help us to fix the problems."
 

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."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"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."
"Over six months, I had two similar issues where searches were performed on field "messages". It exhausted all the memory of the ES node causing an ES crash and a Graylog halt."
"I would like to see a default dashboard widget that shows the topology of the clusters defined for the graylog install."
"There are many other applications in the market that influenced my rating reduction."
"Dashboards, stream alerts and parsing could be improved."
"The product does not have certain advantages, especially the correlation tools. It was not working as per our expectations."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"It may not be as easy to use as Splunk."
"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."
"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 should improve on its log capturing capabilities, the authentication, when a person logs onto a network device."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"Support could improve to make the solution better."
"Its setup is a little bit complex for a distributed environment."
"Since I am currently working with SOAR, I would like to give recommendations regarding Splunk SOAR, as there are very few ready-made apps, and we face problems with integration, which requires us to write to the vendor for help."
"Many of my clients want to get better at Splunk, but they're afraid of using the tool because they feel it's too complex for them."
"Splunk Enterprise Security has not helped improve our organization's business resilience since resilience means the ability to recover from a disaster, and we are not using it in that capacity at all."
"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be cumbersome."
"Their sales support and tech support are really bad. They take really long to respond."
"Professional support is great, but too expensive."
"The correlation of events is the most significant challenge I face when using Splunk Enterprise Security for advanced threat detection."
 

Pricing and Cost Advice

"It's an open-source solution that can be used free of charge."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"We are using the free version of the product. However, the paid version is expensive."
"I use the free version of Graylog."
"Having paid official support is wise for projects."
"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."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
"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."
"Expensive compared to other options."
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."
"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."
"My customers have found the price of the solution to be high."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"Splunk is really expensive compared to all the other tools on the market, including Microsoft Sentinel."
"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."
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
