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'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."
"We chose the product based on the ability to scan for malware using a malware behavioral model as opposed to just a traditional hash-based antivirus. Therefore, it's not as intensive."
"The scalability is good. It can be scaled easily in the production environment."
"The most valuable feature for me is Discover."
"Elastic provides the capability to index quickly due to the reverse indexes it offers. This data is crucial as it contains critical information. The reverse index allows fast data indexing because of Elastic's efficient search engine."
"I use the stack every morning to check the errors and it's just so clear. I don't see any disadvantage to using Logstash."
"Elastic Security offers advanced features such as machine learning and integration with ChatGPT."
"It's simple and easy to use."
"Real-time UDP/GELF logging and full text-based searching."
"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."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"Message forwarding through the in-built module."
"The ability to write custom alerts is key to information security and compliance."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
"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."
"LogRhythm NextGen SIEM covers all our primary security analysis needs. It makes it easier for us to analyze threats and improves our response times. It's a versatile platform that performs queries fast compared to other SIEM solutions."
"In general, the visibility of events and advanced analysis of events are good."
"We now have a central point of monitoring for all potential threats."
"It's reliable and the performance is good."
"Provides visibility into the network."
"As a SIEM, probably the best feature is that it can be tuned effectively. There are very few SIEMs out there that can be effectively tuned to provide you with meaningful information and not be overwhelmed."
"Technical support has always been helpful."
"The initial setup process is very user-friendly."
 

Cons

"Email notification should be done the same way as Logentries does it."
"One limitation of Elastic Security is that it does not have built-in workflows for all tasks. For example, if you need a workflow for compliance, you will need to create a custom workflow."
"This type of monitoring is not very mature just yet. We need more real-time information in a way that's easier to manage."
"We're using the open-source edition, for now, I think maybe they can allow their OLED plugin to be open source, as at the moment it is commercialised."
"There is an area of improvement in the Logs list. The load list may need to be paginated as there are limits."
"Its documentation should be a bit better. I have to spend at least a couple of hours to find the solution for a simple thing. When we buy Elastic, training is not included for free with Elastic. We have to pay extra for the training. They should include training in the price."
"I would like the process of retrieving archived data and viewing it in Kibana to be simplified."
"Better integration with third-party APMs would be really good."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"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."
"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."
"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."
"Graylog can improve the index rotation as it's quite a complex solution."
"There should be some user groups and an auto sign-in feature.​"
"The console installation is an area with a shortcoming in the solution that needs improvement. If LogRhythm SIEM can offer a web console, it would be great."
"I think they probably need to, because a lot of companies are having this cloud-first strategy, where anything that's new has to go into the cloud for some reason."
"It should be improved for automated setup and auto-configuration. There should be ease of integration and ease of setup."
"It will definitely help if the parsing side would be much easier, meaning it would be better if we could easily make adjustments on the parser, both on standard and non-standard log sources."
"The customer support system is time-consuming."
"There are other security technologies outside of this SIEM that should be inside of this SIEM. I can see in their roadmap that they're trying to address a lot of these things, and have these technologies built into the solution, because there is no point in going to another vendor or opening up a second window to obtain the data that you need."
"I would like to see case management become more independent from LogRhythm itself."
"The initial setup is complex. We are using a LogRhythm partner, at least for the first three years, to help with the monitoring and the deployment of it. We are not a big enough environment where we have people that we can dedicate to it right now."
 

Pricing and Cost Advice

"Elastic Stack is an open-source tool. You don't have to pay anything for the components."
"We use the open-source version, so there is no charge for this solution."
"The solution is free."
"The pricing is in the middle. I think it is not an expensive experience if we compare it with big names, for example, QRadar, and also Oxide. I think Elastic Security is quite cheap. I would rate the pricing of this solution a five out of ten."
"I can say that the product is cheaply priced."
"When compared to other products, the price is average or on the low side."
"Elastic Security is free to use."
"The tool's pricing is flexible and comes at unit cost. You don't have to pay for everything."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"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."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"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're using the Community edition."
"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.​​"
"It's an open-source solution that can be used free of charge."
"The setup and licensing for small and medium size businesses is straightforward, though when it comes to the enterprise it pays to keep in mind the possibility for complications given all the extras and add-ons that may be required."
"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."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"In comparison to the competition, they are more affordable. This allows us to do more with less."
"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."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"I would rate the pricing 4 out of 5. There are no additional costs to the standard licensing fees."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
