Strategic Account Executive at a computer software company with 51-200 employees
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.

A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Having one integrated tool helped us by removing the multiple teams, multiple pieces of equipment, and multiple software solutions from the equation."
"Devo saves us hours in every investigation."
"Overall, Devo is awesome, but it's got some room to grow."
"Devo provides good value and, given the quality of the product, I would expect to pay more."
"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."
"It's very, very versatile."
"But from a SaaS standpoint, if not best-in-breed, Devo is certainly in the top-two or top-three."
"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."
"Security Onion is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"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, and it seems like it wasn't tuned properly to handle a large volume of Windows event logs."
"There's room for improvement within the GUI. There is also some room for improvement within the native parsers they support."
"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 price is one problem with Devo."
"Some basic reporting mechanisms have room for improvement."
"One major area for improvement for Devo... is to provide more capabilities around pre-built monitoring."
"The tools in Devo's active ports need enhancement in their investigative capabilities."
"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 initial setup of the solution is a little bit difficult."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
 

Pricing and Cost Advice

"[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."
"We have an OEM agreement with Devo. It is very similar to the standard licensing agreement because we are charged in the same way as any other customer, e.g., we use the backroom."
"I rate the pricing a four on a scale of one to ten, where one is cheap, and ten is expensive."
"Devo is a hosted or subscription-based solution, whereas before, we purchased QRadar, so we owned it and just had to pay a maintenance fee. We've encountered this with some other products, too, where we went over to subscription-based. Our thought process is that with subscription based, the provider hosts and maintains the tool, and it's offsite. That comes with some additional fees, but we were able to convince our upper management it was worth the price. We used to pay under 10k a year for maintenance, and now we're paying ten times that. It was a relatively tough sell to our management, but I wonder if we have a choice anymore; this is where the market is."
"Our licensing fees are billed annually and per terabyte."
"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."
"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."
"Security Onion is a free solution."
"It is an open-source solution."
"Security Onion is an open-source solution."
