"The most valuable feature is definitely the ability that Devo has to ingest data. From the previous SIEM that I came from and helped my company administer, it really was the type of system where data was parsed on ingest. This meant that if you didn't build the parser efficiently or correctly, sometimes that would bring the system to its knees. You'd have a backlog of processing the logs as it was ingesting them."
"Devo provides a multi-tenant, cloud-native architecture. This is critical for managed service provider environments or multinational organizations who may have subsidiaries globally. It gives organizations a way to consolidate their data in a single accessible location, yet keep the data separate. This allows for global views and/or isolated views restricted by access controls by company or business unit."
"The real-time analytics of security-related data are super. There are a lot of data feeds going into it and it's very quick at pulling up and correlating the data and showing you what's going on in your infrastructure. It's fast. The way that their architecture and technology works, they've really focused on the speed of query results and making sure that we can do what we need to do quickly. Devo is pulling back information in a fast fashion, based on real-time events."
"The strength of Devo is not only in that it is pretty intuitive, but it gives you the flexibility and creativity to merge feeds. The prime examples would be using the synthesis or union tables that give you phenomenal capabilities... The ability to use a synthesis or union table to combine all those feeds and make heads or tails of what's going on, and link it to go down a thread, is functionality that I hadn't seen before."
"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."
"I like the correlation and the alerting."
"Open source and user friendly."
"Graylog's search functionality, alerting functionality, user management, and dashboards are useful."
"Its integration is most valuable. Its UI is also pretty much easy."
"The reporting aspect is good and it does what I need it to do."
"Easy to deploy and simple to use."
"The solution has proven to be quite stable."
"The flexibility of the search capability is most valuable. You can use it for more than just a basic log aggregator. It is powerful in that regard."
"Our clients are easily able to modify and evolve their implementations."
"We have found all the features useful. However, the dashboarding and logging have been very helpful. Additionally, the log analysis does a great job."
"What is nice about the solution is that it makes it easy to build the queries, search for the events and then do analysis."
"From our experience, the Devo agent needs some work. They built it on top of OS Query's open-source framework. It seems like it wasn't tuned properly to handle a large volume of Windows event logs. In our experience, there would definitely be some room for improvement. A lot of SIEMs on the market have their own agent infrastructure. I think Devo's working towards that, but I think that it needs some improvement as far as keeping up with high-volume environments."
"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."
"One major area for improvement for Devo... is to provide more capabilities around pre-built monitoring. They're working on integrations with different types of systems, but that integration needs to go beyond just onboarding to the platform. It needs to include applications, out-of-the-box, that immediately help people to start monitoring their systems. Such applications would include dashboards and alerts, and then people could customize them for their own needs so that they aren't starting from a blank slate."
"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."
"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."
"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."
"Some third-parties don't have specific API connectors built, so we had to work with Devo to get the logs and parse the data using custom parsers, rather than an out-of-the-box solution."
"Lacks sufficient documentation."
"I would like to see some kind of visualization included in Graylog."
"Graylog can improve the index rotation as it's quite a complex solution."
"It could be more user friendly, in terms of the end-user experience."
"Splunk is query-based, which is not the case with most cybersecurity tools. It is based on search queries and can be difficult to use. It would be good if they can make it easier to understand how to create search queries. They can improve the knowledge base for better understanding. To create your dashboard, you need to have a search query. We have multiple firewalls in our company, and we need a dashboard for them. It would be helpful if a default firewall dashboard is included in Splunk to make monitoring easier. If a dashboard is available for a security device, the operation part will be more efficient. We won't have to follow a manual process for this."
"Its setup is a little bit complex for a distributed environment. Their support can also be better. If we miss the response for more than a week, they usually close the case. Sometimes, it can take us more than a week to reply."
"I feel the solution to be too slow."
"The solution could improve by increasing the performance. We have run into problems when large amounts of data are processed."
"Technical support needs to be more responsive."
"From the commercial point of view, they have to bring down their costs."
"Splunk needs to be able to hold more days of data. At the moment it only holds three months of data."
