Featured Reviews

Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.
Mahmoud Younes - PeerSpot reviewer
Reliable installation and diverse use cases provide strong value
IBM Security QRadar has some areas for improvement. We have missed some DSM components. We need to customize logs where there is no DSM or connector for certain products. We can integrate but we have missed the DSM, which is the connector to pass logs coming from different applications. For example, with a university customer, we tried onboarding Canvas service. IBM Security QRadar does not support Canvas, so we had to create custom scripts and workarounds to pull logs from Canvas.

Quotes from Members

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

Pros

"Open source and user friendly."
"Real-time UDP/GELF logging and full text-based searching."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"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."
"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."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"The product is scalable. The solution is stable."
"Graylog is very handy."
"The ability to transition from microscopic to macroscopic view, instantly, is very good."
"The monitoring and dashboards are great."
"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 feature that I have found most valuable is how it monitors the real network. That is its leading security feature."
"Flexible and valuable product that is modular, so you can easily set up a roadmap for your clients."
"IBM Security QRadar has significantly improved our incident response procedures."
"I like that it's easy to use and the performance is good."
"We've found the solution to be scalable."
 

Cons

"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."
"There should be some user groups and an auto sign-in feature.​"
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"I would like to see some kind of visualization included in Graylog."
"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-"
"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."
"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."
"The IBM support can be better."
"Do your research before implementing it, because it is tough to implement."
"There are many types of AI, and this AI is very limited in SQL and features. There may be potential for improvement."
"While the interface is easy to use, it could be a little more responsive."
"IBM Security QRadar lacks automated response. With this feature, there's no need to visit VirusTotal or other sites for IP reputation. There should be a small plug-in where users can click to retrieve details about the reputation and organization of public IP."
"There should be more opportunity for community kind of distribution where, for example, if there was a zero-day threat targeting companies."
"The product is good, but one feature they should have is an Elasticsearch. Currently, in QRadar, there are no Elasticsearch criteria."
"IBM needs to invest more into the collaboration with other vendors."
 

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."
"It's an open-source solution that can be used free of charge."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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."
"If you want something that works and do not have the money for Splunk or QRadar, take Graylog.​​"
"IBM QRadar User Behavior Analytics is an application framework and you can install many applications without any additional costs."
"Our licensing costs for this solution is on a yearly basis."
"The price of this solution is reasonable."
"There is a license required for this solution. There are some limitations depending on what license you purchase."
"The pricing is higher but cheaper than others and there are no additional costs."
"The price of this product is high."
"They can give us some scalability and flexibility on pricing. If its pricing can be reduced, it would help a lot of customers in bringing in a new SIEM environment and grow business in the market. If I start a license today and take around 10,000 EPS, and after a month, there is an increase in the number of clients on my platform, I can increase the number of licenses. I can add 5,000 EPS on a yearly basis."
"It is a perpetual license that we have for the event collector. The licensing is done based on the number of events and flows that you receive on this particular device. These are perpetual licenses, which means once you purchase them, they don't expire, which means that the support to IBM is definitely renewed after every one year. We have an enterprise agreement with IBM, which puts the cost in a totally different category as compared to someone who is not an IBM partner and is approaching IBM for this solution. We were able to get massive discounts. To give you an idea, we recently purchased 30,000 event licenses, and it costs around $480,000. It is definitely not a cheap product. We have licenses for about 270,000 events per second and 3 million flows per second. All the appliances and their events and flows are basically clubbed together and charged or rather calculated through a single source. The console receives all the details from all the event processes that we have globally. So, the license that we have is a single license for 270,000 events per second and 3 million flows per second, but that can be managed centrally. I was only part of the secondary purchase, which was 30,000 events per second for about $480,000. You can calculate how much we paid for 270,000 events. Reducing its price would be a compromise. We have already used a lower-priced product in the form of NNT, but we had to get rid of it because it was not doing the job that we actually wanted to do. You get what you pay for."
