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.

Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.

Quotes from Members

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

Pros

"This had increased productivity for the dev and support teams, because we are directly notifying them."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"The solution's most valuable feature is its new interface."
"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."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"Graylog Enterprise has positively impacted my organization by significantly minimizing our workload and making it easier to identify any issues in a service."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"QRadar shows very effective correlations. If you combine all the logins plus user behavior and the current intelligence, it gives a very good correlation for business. I think it reduces the false positives in user activity monitoring because there is a lot of social information to correlate with other data."
"I suggest others to go with IBM Security QRadar because it is an IBM product and many companies and bank environments are using IBM Security QRadar because of its strong visibility and analysis capabilities."
"It saves a lot of time. We integrate the customer's firewall with all their networking devices."
"There are a lot of great out-of-the-box features included."
"QRadar, Splunk, and ArcSight are SIEM solutions with built-in AI/ML features. They can do the complete investigation and alert the admin about what is happening. They can also do the root cause analysis. There are many other features that come with QRadar. It has a more granular log, so you can integrate with various non-IT as well as IT-based components. You can get unstructured data to the SIEM data, and you can identify more what is happening in the network or what is happening in the central head office. You can also identify what is happening between your remote offices. You can also use it to identify what the users in the field are doing on their devices and how things are moving. From the integration point of view, it is very centric. It gives complete control centrally. If a user is not connected to the system, whenever he comes online, we can see the policy updates over the Internet, and we can ensure that the data that is supposed to be protected is protected."
"The visibility it gives you into your infrastructure has been great."
"When it comes to QRadar, they can do the correlation and not only in networks but also endpoints. This is one of the good features that we have noticed."
"An engineer can live-monitor all the flow happening in real-time. This would help us a lot while investigating a case, and it would even help us with preventive actions."
 

Cons

"When it comes to configuring the processing pipeline, writing the rules can be very tedious, especially since the documentation isn't extensive on how the functions provided for these rules work."
"With technical support, you are on your own without an enterprise license."
"There are many other applications in the market that influenced my rating reduction."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"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 some kind of visualization included in Graylog."
"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community."
"Graylog can improve the index rotation as it's quite a complex solution."
"The solution lacks some maturity."
"IMB should reduce the pricing, or reduce some of the features for a more economical solution for the customer."
"I would like to see the update process simplified."
"IBM QRadar User Behavior Analytics could improve machine learning use cases because they are limited and most of the use cases are rule-based. They should develop more use cases, such as in Securonix or Exabeam because they will detect a threat. Using machine learning is mainly on the correlation rules, but if you think about Exabeam or Securonix, they detect using machine learning or machine learning-based algorithms."
"QRadar needs a lot of fine tuning"
"Needs better visualization options beyond the time series charts and a few other options that they have."
"The initial setup was complex, and it took six months."
"The pricing of the solution is a bit high. If they could lower it, that would be ideal."
 

Pricing and Cost Advice

"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."
"We are using the free version of the product. However, the paid version is expensive."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"I use the free version of Graylog."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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.​​"
"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."
"IBM Security QRadar is a very expensive tool."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate IBM Security QRadar's pricing a five out of ten."
"There is a license to use this solution, which is paid annually. However, there are subscription options available."
"Licensing can be costly depending on your architecture."
"I think my company pays for the license yearly."
"It's too expensive."
"There is an annual license required for this solution."
"The price of this solution is a little high."
