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.

Transforms logs for real-time insights and seamless reporting
Logstash is used for transforming logs, and you can use many plugins in Logstash. Logstash works with configuration files that contain three main parts: an input part, a filter part, and an output part. In the input part, we can take logs from many sources such as Beats, files, or Kafka. The filter part is used to filter the logs that are shipped from Beats. From my understanding and experience with Logstash, it is usually used for processing logic, meaning I can control what fields should be transferred to Elastic and what fields shouldn't be transferred. This is the main function I use Logstash for. Elastic is a famous open-source searching engine that helps operation teams speed up the investigation process and provides real-time insights for performance reporting.

Quotes from Members

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

Pros

"IBM QRadar is great help from its security event monitoring to data center and NOC troubleshooting of issues hard for other departments to spot."
"Integrations are quite a useful and key feature of this solution. It has integration with the CVSS score, which is a central point for all the data and scores about the threats. There is an IBM Bluemix dashboard that is integrated with the CVSS score."
"I think the QDI is very good."
"I think it has improved our organization by the speed at which I can run queries compared to other software that I've used in the past."
"It'll get you from point A to B."
"We were using a different solution, and we moved to QRadar; it has some more benefits than our previous solution, and we have totally transferred to QRadar now."
"This platform can collect and normalize data better than just about anything (if you want it to), but it will not be useful if it is not presented in a useful way."
"Flexible and valuable product that is modular, so you can easily set up a roadmap for your clients."
"I can collect logs from various data sources, including hardware."
"The transformation means we ship the logs in the way that we want them to be presented in Kibana, which is the main function we use Logstash for."
"The functionality of Logstash is quite easy to implement and the plugin ecosystem of Logstash is great, with plugins for shell script monitoring and SQL monitoring working well with the tool."
"Everything aligns well with improving our organization."
"Logstash has numerous plugins for inputs and outputs, allowing it to work well in environments that do not contain other Elastic components."
"We have three or four Logstash servers for high availability."
 

Cons

"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."
"QRadar's issue is it needs to add behavioral analytics."
"I would like to see the update process simplified."
"The technical support is poor. Mostly because when I open a PMR for IBM, I am stuck with Level 1 staff."
"They should introduce some automation into the product."
"Reporting should be very good, and a proper integration with cloud, not only the IBM cloud, but with other clouds also."
"There are reports that I would like to generate that are either not included, or I cannot find."
"The first area for improvement is the cost. It's a little bit too expensive for us."
"Almost all the research can be very bad. We still have a problem with importing the log system."
"An enhancement we could implement is the ability to cluster Logstash to exist in more than one node."
"There can be a UI to implement with Logstash. Currently, I have to work with config files and everything."
"The product needs to improve its compatibility."
"We still have a problem with importing the log system."
"Elastic does not provide proper support for Logstash worldwide, and I rate their technical support as one out of ten."
 

Pricing and Cost Advice

"It's not expensive for the resources that it gives you."
"Our licensing costs for this solution is on a yearly basis."
"Pricing is good."
"It's too expensive. The licensing is also a little bit difficult to understand because you have to license it per event and per number of flows."
"IBM's Qradar is not for small companie. Unfortunately, it would be 'overkill' to place it plainly. The pricing would be too much."
"The licensing is also overly complex, as there is a need to buy the work load performance monitoring separately."
"IBM QRadar User Behavior Analytics is an application framework and you can install many applications without any additional costs."
"When it comes to the initial pricing there can be a huge discount from there side and also I think they are open to competing with other products."

Questions from the Community

What SOC product do you recommend?

What do you like most about Logstash?
I can collect logs from various data sources, including hardware.
What needs improvement with Logstash?
Customization can be automated with Logstash, but it is at the developer's disposal. The developer has to do it, not the tool as such. There is scope for optimization, but that is all outside the t...
