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.

Centralized threat monitoring has improved visibility but demands complex setup and configuration

The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Quotes from Members

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

Pros

"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."

"Having one integrated tool helped us by removing the multiple teams, multiple pieces of equipment, and multiple software solutions from the equation."

"Devo provides good value and, given the quality of the product, I would expect to pay more."

"The alerting is much better than I anticipated. We don't get as many alerts as I thought we would, but that nobody's fault, it's just the way it is."

"The ROI has been great as we could launch it in a few months instead of a couple of years, and when you put all the costs together, it is less to have done it than with the open source approach."

"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."

"It is a joy to partner and be able to work with this kind of system."

"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."

More Devo pros

"We use Security Onion for internal vulnerability assessment."

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

"Security Onion has positively impacted my organization by greatly improving our security posture, making alert triage easier to handle, simplifying the analysis of threats, and decreasing the cost of threat analysis and detection."

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

Cons

"The Activeboards feature is not as mature regarding the look and feel."

"Devo has a lot of cloud connectors, but they need to do a little bit of work there."

"Where Devo has room for improvement is the data ingestion and parsing. We tend to have to work with the Devo support team to bring on and ingest new sources of data."

"Technical support needs to be more direct. For example, when we submit a ticket, the support team will delegate a task to the operations team, for example, or various other teams."

"I would like to have the ability to create more complex dashboards."

"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 always room to reduce the learning curve over how to deal with events and machine data. They could make the machine data simpler."

"We only use the core functionality and one of the reasons for this is that their security operation center needs improvement."

More Devo cons

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

"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."

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

"The product is not easy to learn."

Pricing and Cost Advice

"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."

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

"[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 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."

"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."

"It's a per gigabyte cost for ingestion of data. For every gigabyte that you ingest, it's whatever you negotiated your price for. Compared to other contracts that we've had for cloud providers, it's significantly less."
