Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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.""The user experience [is] well thought out and the workflows are logical. The dashboards are intuitive and highly customizable.""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.""The user interface is really modern. As an end-user, there are a lot of possibilities to tailor the platform to your needs, and that can be done without needing much support from Devo. It's really flexible and modular. The UI is very clean.""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 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.""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.""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."

"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps.""One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview.""Graylog's search functionality, alerting functionality, user management, and dashboards are useful.""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're using the Community edition, but I know that it has really good dashboarding and alerts.""I like the correlation and the alerting."

More Graylog Pros →

"It's basically one of the best SIEM products on the market.""It allows us to digest the information, the data, the different data streams, so we can make decisions based upon information that we receive, and it is pretty robust.""The completeness of the solution is what we like the most.""The most valuable features are how stable and easy to use Splunk is.""The connections to the database are very good and updating the data files is simple to do. The dashboards are useful and user-friendly.""The ability to analyze huge amounts of sales data and accurate prediction of sales forecasting is the most valuable feature.""We can easily configure things as required in relation to our use cases.""It's the completeness of the solution that we like the most."

Cons
"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.""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.""There is room for improvement in the ability to parse different log types. I would go as far as to say the product is deficient in its ability to parse multiple, different log types, including logs from major vendors that are supported by competitors. Additionally, the time that it takes to turn around a supported parser for customers and common log source types, which are generally accepted standards in the industry, is not acceptable. This has impacted customer onboarding and customer relationships for us on multiple fronts.""I would like to have the ability to create more complex dashboards.""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.""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.""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.""Some basic reporting mechanisms have room for improvement. Customers can do analysis by building Activeboards, Devo’s name for interactive dashboards. This capability is quite nice, but it is not a reporting engine. Devo does provide mechanisms to allow third-party tools to query data via their API, which is great. However, a lot of folks like or want a reporting engine, per se, and Devo simply doesn't have that. This may or may not be by design."

More Devo Cons →

"It would be great if Graylog could provide a better Python package in order to make it easier to use for the Python community.""Graylog needs to improve their authentication. Also, the fact that Graylog displays logs from the top down is just ridiculous.""More customization is always useful.""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.""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."

More Graylog Cons →

"It needs a better way to export dynamic views without requiring a ton of code and user/pw.""Splunk could be improved by reducing the cost. The cost is one of the biggest challenges for us in keeping to our production requirements.""It needs integration with a configuration management solution.""The support that is included with the standard licensing fee is very bad.""The prices are complicated as we operate in a small third-world country.""It needs integration with a configuration management solution.""There can be a bit of complexity around some fields during the initial setup.""We had some connections issues with the solution at the beginning."

Pricing and Cost Advice
  • "I'm not involved in the financial aspect, but I think the licensing costs are similar to other solutions. If all the solutions have a similar cost, Devo provides more for the money."
  • "Devo is definitely cheaper than Splunk. There's no doubt about that. The value from Devo is good. It's definitely more valuable to me than QRadar or LogRhythm or any of the old, traditional SIEMs."
  • "[Devo was] in the ballpark with at least a couple of the other front-runners that we were looking at. Devo is a good value and, given the quality of the product, I would expect to pay more."
  • "Be cautious of metadata inclusion for log types in pricing, as there are some "gotchas" with that."
  • "Devo was very cost-competitive... Devo did come with that 400 days of hot data, and that was not the case with other products."
  • "Our licensing fees are billed annually and per terabyte."
  • "I like the pricing very much. They keep it simple. It is a single price based on data ingested, and they do it on an average. If you get a spike of data that flows in, they will not stick it to you or charge you for that. They are very fair about that."
  • "Pricing is based on the number of gigabytes of ingestion by volume, and it's on a 30-day average. If you go over one day, that's not a big deal as long as the average is what you expected it to be."
  • More Devo Pricing and Cost Advice →

  • "It's an open-source solution that can be used free of charge."
  • "We're using the Community edition."
  • "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."
  • "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."
  • More Graylog Pricing and Cost Advice →

  • "I think that most of the monitoring solutions are expensive."
  • "I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
  • "Our customers often complain that the price of Splunk is too high."
  • "Licensing is a yearly, one-time cost."
  • "The price is comparable."
  • "The pricing model is expensive and a nightmare based on the amount of data."
  • "The solution is a little expensive."
  • "It is economical than other solutions."
