"The thing that Devo does better than other solutions is to give me the ability to write queries that look at multiple data sources and run fast. Most SIEMs don't do that. And I can do that by creating entity-based queries. Let's say I have a table which has Okta, a table which has G Suite, a table which has endpoint telemetry, and I have a table which has DNS telemetry. I can write a query that says, 'Join all these things together on IP, and where the IP matches in all these tables, return to me that subset of data, within these time windows.' I can break it down that way."
"Devo helps us to unlock the full power of our data because they have more than 450 parsers, which means that we can ingest pretty much any type of log data."
"Even if it's a relatively technical tool or platform, it's very intuitive and graphical. It's very appealing in terms of the user interface. The UI has a graphically interface with the raw data in a table. The table can be as big as you want it, depending on your use case. You can easily get a report combining your data, along with calculations and graphical dashboards. You don't need a lot of training, because the UI is relatively very intuitive."
"The ability to have high performance, high-speed search capability is incredibly important for us. When it comes to doing security analysis, you don't want to be doing is sitting around waiting to get data back while an attacker is sitting on a network, actively attacking it. You need to be able to answer questions quickly. If I see an indicator of attack, I need to be able to rapidly pivot and find data, then analyze it and find more data to answer more questions. You need to be able to do that quickly. If I'm sitting around just waiting to get my first response, then it ends up moving too slow to keep up with the attacker. Devo's speed and performance allows us to query in real-time and keep up with what is actually happening on the network, then respond effectively to events."
"The user experience [is] well thought out and the workflows are logical. The dashboards are intuitive and highly customizable."
"One of the biggest features of the UI is that you see the actual code of what you're doing in the graphical user interface, in a little window on the side. Whatever you're doing, you see the code, what's happening. And you can really quickly switch between using the GUI and using the code. That's really useful."
"In traditional BI solutions, you need to wait a lot of time to have the ability to create visualizations with the data and to do searches. With this kind of platform, you have that information in real-time."
"It's very, very versatile."
"Elastic has a lot of beats, such as Winlogbeat and Filebeat. Beats are the agents that have to be installed on the terminals to send the data. When we install beats or Elastic agents on every terminal, they don't overload the terminals. In other SIEM solutions such as Splunk or QRadar, when beats or agents are installed on endpoints, they are very heavy for the terminals. They consume a lot of power of the terminals, whereas Elastic agents hardly consume any power and don't overload the terminals."
"It's not very complicated to install Elastic."
"The most valuable feature is the speed, as it responds in a very short time."
"Just the ability to do a lot more than just up-down is nice, which a lot of people take for granted."
"We've found the initial setup to be quite straightforward."
"Its flexibility is most valuable. We can have a number of scenarios, and we can get logs from anything. If we know how to use Logstash, we can tweak it in many ways. This makes the logging search on Elastic very easy."
"The cost is reasonable. It's not overly pricey."
"ELK is open-source, and it will give you the framework you need to build everything from scratch."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"We're using the Community edition, but I know that it has really good dashboarding and alerts."
"I like the correlation and the alerting."
"I would like to have the ability to create more complex dashboards."
"There's always room to reduce the learning curve over how to deal with events and machine data. They could make the machine data simpler."
"There's room for improvement within the GUI. There is also some room for improvement within the native parsers they support. But I can say that about pretty much any solution in this space."
"Devo has a lot of cloud connectors, but they need to do a little bit of work there. They've got good integrations with the public cloud, but there are a lot of cloud SaaS systems that they still need to work with on integrations, such as Salesforce and other SaaS providers where we need to get access logs."
"The biggest area with room for improvement in Devo is the Security Operations module that just isn't there yet. That goes back to building out how they're going to do content and larger correlation and aggregation of data across multiple things, as well as natively ingesting CTI to create rule sets."
"We only use the core functionality and one of the reasons for this is that their security operation center needs improvement."
"Technical support could be better."
"The Activeboards feature is not as mature regarding the look and feel. Its functionality is mature, but the look and feel is not there. For example, if you have some data sets and are trying to get some graphics, you cannot change anything. There's just one format for the graphics. You cannot change the size of the font, the font itself, etc."
"The solution does not have a UI and this is one of the reasons we are looking for another solution."
"I would like the process of retrieving archived data and viewing it in Kibana to be simplified."
"With Elastic, you have to build the use cases for the specific requirement. Other products have a simple integration and more use cases to integrate out-of-the-box solutions for SIEM."
"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 should be a simulation environment to check whether my Elastic implementation is functioning perfectly fine. Other solutions have their own Android and iOS applications that I can install on my mobile so that I am continuously connected to the SIEM."
"The Integration module could be improved. It is a pain to build integration with any product. We have to do parking and so on. It's not like other commercial solutions that use profile integration. I would also see more detection features on the SIEM side."
"There isn't really a very good user experience. You need a lot of training."
"We are paying dearly for the guy who is working on the ELK Stack. That knowledge is quite rare and hard to come by. For difficulty and availability of resources, I would rate it a five out of 10."
"I would like to see some kind of visualization included in Graylog."
"More customization is always useful."
"Graylog can improve the index rotation as it's quite a complex solution."
