Has improved investigative workflows with interactive dashboards and simplified data correlation

The data analytics cloud component focuses on real-time analytics, which is very impressive. The SIEM collects and correlates logs data from different sources and can integrate with ServiceNow, hardware asset management, and software asset management. The security orchestration, automation, and response (SOAR) is another valuable feature. The security data platform serves as the foundation of Devo. Regarding advanced query capabilities, Devo offers several models including query logs, visual query builder, language integrated query, and SQL, with SQL being the most frequently used querying data capability. The single pane of glass that Devo offers is the SOC. The tools in Devo's active ports are for investigating, not just viewing data. They are more interactive than other market solutions. The drill-down reports capabilities allow analysts to click on any element in a widget. When they see a spike in a line chart for a failed login, which could be a true or false attempt, they can click that spike, and a table widget on the same active board instantly populates with raw logs of data for those specific failed logins. This is particularly important for enterprise companies with numerous endpoints and users. The dynamic filtering of inputs significantly reduces the time cybersecurity analysts spend trying to figure out failed logins and identifying false positives.

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 most useful feature for us, because of some of the issues we had previously, was the simplicity of log integrations. It's much easier with this platform to integrate log sources that might not have standard logging and things like that."

"Devo has a really good website for creating custom configurations."

"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."

"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 drill-down reports capabilities allow analysts to click on any element in a widget. When they see a spike in a line chart for a failed login, which could be a true or false attempt, they can click that spike, and a table widget on the same active board instantly populates with raw logs of data for those specific failed logins."

"The user experience [is] well thought out and the workflows are logical. The dashboards are intuitive and highly customizable."

"The most powerful feature is the way the data is stored and extracted. The data is always stored in its original format and you can normalize the data after it has been stored."

More Devo pros

"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."

"Security Onion is the most mature solution in the market."

"We use Security Onion for internal vulnerability assessment."

Cons

"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."

"An admin who is trying to audit user activity usually cannot go beyond a day in the UI. I would like to have access to pages and pages of that data, going back as far as the storage we have, so I could look at every command or search or deletion or anything that a user has run. As an admin, that would really help. Going back just a day in the UI is not going to help, and that means I have to find a different way to do that."

"The overall performance of extraction could be a lot faster, but that's a common problem in this space in general. Also, the stock or default alerting and detecting options could definitely be broader and more all-encompassing. The fact that they're not is why we had to write all our own alerts."

"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 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."

"There are some issues from an availability and functionality standpoint, meaning the tool is somewhat slow. There were some slow response periods over the past six to nine months, though it has yet to impact us terribly as we are a relatively small shop. We've noticed it, however, so Devo could improve the responsiveness."

"Technical support could be better."

More Devo cons

"Security Onion's user interface could be improved."

"The product is not easy to learn."

"The initial setup of the solution is a little bit difficult."

Pricing and Cost Advice

"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."

"Devo was very cost-competitive... Devo did come with that 400 days of hot data, and that was not the case with other products."

"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 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."

"I rate the pricing a four on a scale of one to ten, where one is cheap, and ten is expensive."

"It's very competitive. That was also a primary draw for us. Some of the licensing models with solutions like Splunk and Sentinel were attractive upfront, but there were so many micro-charges and services we would've had to add on to make them what we wanted. We had to include things like SOAR and extended capabilities, whereas all those capabilities are completely included with the Devo platform. I haven't seen any additional fee."

"The way Devo prices things is based on the amount of data, and I wish the tiers had more granularity. Maybe at this point they do, but when we first negotiated with them, there were only three or four tiers."

"Be cautious of metadata inclusion for log types in pricing, as there are some "gotchas" with that."
