Usama Khan

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

"But from a SaaS standpoint, if not best-in-breed, Devo is certainly in the top-two or top-three."

"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'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."

"More than anything, we have seen ROI in the amount of time saved during investigations."

"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 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."

"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."

"Being able to build and modify dashboards on the fly with Activeboards streamlines my analyst time because my analysts aren't doing it across spreadsheets or five different tools to try to build a timeline out themselves. They can just ingest it all, build a timeline out across all the logging, and all the different information sources in one dashboard. So, it's a huge time saver. It also has the accuracy of being able to look at all those data sources in one view. The log analysis, which would take 40 hours, we can probably get through it in about five to eight hours using Devo."

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."

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

Cons

"However, the incident and threat detection is not what we had hoped for."

"One major area for improvement for Devo... is to provide more capabilities around pre-built monitoring."

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

"The price is one problem with Devo."

"Some of the documentation could be improved a little bit. A lot of times it doesn't go as deep into some of the critical issues you might run into. They've been really good to shore us up with support, but some of the documentation could be a little bit better."

"It's stable but it's not extremely stable."

"The tools in Devo's active ports need enhancement in their investigative capabilities."

"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."

More Devo cons

"The product is not easy to learn."

"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."

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."

"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."

"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."

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

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

"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."

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

"[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."

More Devo pricing and cost advice

"It is an open-source solution."

"Security Onion is a free solution."
