Featured Reviews

SyedAli17 - PeerSpot reviewer
Centralized monitoring improves security posture through rapid data processing
The processing part of Elastic Security ( /products/elastic-security-reviews ) is very interesting for us since we handle almost 7,000 to 8,000 alerts per minute. We require rapid processing speed for alerts and event data, and Elastic Security is very efficient at handling this level of data. Additionally, Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing.
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.
Mokhammad Rakhman - PeerSpot reviewer
User-friendly dashboard and machine learning capabilities improve threat hunting efficiency
LogRhythm SIEM has strong machine-learning capabilities with behavioral rules and analysis. The seamless integration for case management, along with a user-friendly dashboard user interface, makes tasks like threat hunting more efficient. Analytics and behavioral analysis help me save time with rule creation. Its scalability allows me to add components as needed. Overall, LogRhythm SIEM offers end-to-end visibility with a reasonable price.

Quotes from Members

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

Pros

"It is very quick to react. I can set it to check anomalies or suspicious behavior every 30 seconds. It is very fast."
"The most valuable feature is the speed, as it responds in a very short time."
"Enables monitoring of application performance and the ability to predict behaviors."
"It's a good platform and the very best in the current market. We looked at the Forester report from December 2022 where it was said to be a leader."
"The intelligence of the system has been very impressive. It's not quite AI, but the technical bit where it correlates information, based on the seen attacks within an organization is good."
"The most valuable feature is the search function, which allows me to go directly to the target to see the specific line a customer is searching for."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"The most valuable feature is the ability to collect authentication information from service providers."
"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."
"It is used as a log manager/SIEM. It provides visibility into the infrastructure and security related events."
"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."
"UDP is a fast and lightweight protocol, perfect for sending large volumes of logs with minimal overhead."
"I am very proud of how very stable the solution is."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"The product is scalable. The solution is stable."
"Graylog is very handy."
"It has allowed us to dive deeper into our network and figure out what is going on by parsing logs properly and being able to reduce the time it takes to work cases down from seven days to approximately two days."
"NextGen SIEM's most valuable feature is its user-friendliness."
"Compliance reporting is another great feature of this product. It has built in reports right out of the box."
"I like LogRhythm's ease of use. The solution has improved compared to previous versions. It had many issues before, like integration, the console, creating reports, false positives, etc. The AI engine has made it stronger in the latest version."
"Overall, my rating for LogRhythm SIEM is nine out of ten."
"Provides visibility into the network."
"LogRhythm has increased productivity because all the tools that we need are in the web UI, allowing us to find threats on our network fast and efficiently."
"The user interface is good."
 

Cons

"Elastic sometimes does not correctly identify threats or anomalies. It might not classify an issue as malicious or critical accurately."
"Authentication is not a default in Kibana. We need to have another tool to have authentication and authorization. These two should be part of Kibana."
"The tool needs to integrate with legacy servers. Big companies can have legacy servers that may not always be updated."
"We'd like better premium support."
"The setup process is complex. You need a solid working knowledge of networking, operating systems, and a little programming."
"If you compare this with CrowdStrike or Carbon Black, they can improve."
"It's a little bit of a learning curve to understand the logic of searching for things and trying to find what you're looking for in Elastic Security."
"The solution should generate an automatic product that integrates with ELK Stack to use artificial intelligence."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"The area in Graylog that needs to be improved or enhanced would be the integrations."
"With technical support, you are on your own without an enterprise license."
"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."
"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."
"Dashboards, stream alerts and parsing could be improved."
"More customization is always useful."
"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 really like to see some type of group or global management for RIM policies,"
"I would like to see case management become more independent from LogRhythm itself."
"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."
"We would like to see more things out of the console into the web UI. I guess this is what they are doing in 7.4."
"For our market, the solution is quite expensive. It would be ideal if they could work on and improve their existing pricing plans to help make it more affordable in our country."
"It should be improved for automated setup and auto-configuration. There should be ease of integration and ease of setup."
"The software needs to work on its pricing."
"Parsing is totally controlled by LogRhythm and they do not allow any partner or any third-party to handle this part and this is a key challenge on my end."
 

Pricing and Cost Advice

"The solution is free."
"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."
"I can say that the product is cheaply priced."
"Compared to other products such as Dynatrace, this is one of the cheaper options."
"There is no charge for using the open-source version."
"Its price is fine. Its licensing works on a yearly basis. We have to renew the license every year. I also have a good experience with Darktrace. When we buy Darktrace, we get training free of cost, which is not there in Elastic. We have to pay extra for training. There is certainly room for improvement."
"We use the open-source version, so there is no charge for this solution."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"It's an open-source solution that can be used free of charge."
"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."
"We are using the free version of the product. However, the paid version is expensive."
"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."
"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."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"Having paid official support is wise for projects."
"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."
"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"I would recommend that whatever sales quotes to them upfront, they will probably go up. Because they are probably going to outgrow that very quickly or once they start getting everything into it, they are going to have to move up anyway."
"It is a very cost-effective solution."
"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"NextGen SIEM's pricing is moderate."
