Team Lead Soc at a tech services company with 51-200 employees

Advanced threat hunting has improved SOC visibility and now supports faster incident response

Devo can improve in how its connectors enhance integration with third-party tools. Devo's architecture works by having you deploy a relay server in the data center of the client side and Devo SIEM is basically on the AWS cloud. There are specific ports which are enabled on the relay server, which are 514 and 13000, 13151, 152. However, when we talk about databases and custom integrations, there are not default ports in the relay server. No default ports are defined. For JDBC drivers, the port number is 1433, but it is not in the relay server. You have to add it manually. For Oracle RDBMS, the port is 1521, and it is also not there by default. I would appreciate more third-party integrations including Fortinet and others. Machine learning models can also be improved. Playbooks in the SOAR can also be improved. Regarding playbooks for automation, we utilize playbooks for automation in SOAR for automated IOC blocking on a firewall, on a web application firewall, on DNS security, etc. The only option for us to run the playbook is to schedule the job for it. However, if I want to manually run the playbook, there is no option for doing so. This needs improvement.

Centralized monitoring has strengthened threat detection and supports faster incident investigations

Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization. Security Onion integrates well with our existing tools, primarily using Linux systems in our organization, allowing us to monitor logs and manage threat detection and operations in the public cloud effectively. Security Onion is very helpful in meeting compliance requirements and supports regular standards for our environment. I advise organizations that use Linux or have network security knowledge to consider Security Onion, as it satisfies requirements such as threat detection and log management systems. I would rate this review eight out of ten.

Quotes from Members

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

Pros

"When we show the people who are in charge of getting funding that we saved this number of man-hours, which correlates to this number of dollars, they're more willing to fight to get that funding for the next fiscal year."

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

"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."

"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 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."

"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."

"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."

More Devo pros

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

"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."

"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

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

"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."

"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."

"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."

"Their documentation could be better. They are growing quickly and need to have someone focused on tech writing to ensure that all the different updates, how to use them, and all the new features and functionality are properly documented."

"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 biggest area with room for improvement in Devo is the Security Operations module that just isn't there yet."

More Devo cons

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

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

"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."

"The product is not easy to learn."

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."

"Our licensing fees are billed annually and per terabyte."

"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."

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

"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."

"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."

"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."

"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."
