Advanced threat detection has improved investigations but complexity and resource use need refinement

LogRhythm SIEM could learn from Wazuh, as Wazuh has a built-in mechanism that allows you to write custom scripting and scripts through languages that Wazuh can then trigger, which is somewhat better and more matured in Wazuh compared to LogRhythm SIEM. Additionally, the parsers that I write for LogRhythm SIEM tend to get quite complex for log parsing, while with Wazuh, I can achieve a similar parser with much less complexity. Those are some of the pain points that some of our customers have been expressing. If LogRhythm SIEM could make a lightweight version of their solution, that would be quite competitive because some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity. Therefore, they have been moved to Wazuh, which I am deploying for them. Even though LogRhythm SIEM has extremely good capabilities, their resource utilization is too heavy for certain customers, so if they could make a separate, lightweight version, that would be quite beneficial.

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

"Having a unified end-to-end platform is really important to me, because I am the only security professional at the college."

"The PCI compliance pieces that help us produce reports for our external auditor, and their support."

"The feature that makes it usable is the web interface."

"The advanced intelligence engine, in fact the whole suite, is very powerful and as far as I’m concerned, it’s one of the best for security management."

"It has centralized monitoring for our security operations. Therefore, it improves our analysts' work."

"It makes it possible to stay aware of much more of what's going on; we get an overview, a macro view that we can zoom in on as opposed to prior to that when we had individual panes of glass and might be stuck in the firewall interface for half a day while something going on is not getting addressed that we really should probably investigate."

"Hands down, one of the best security platforms I've seen, easy to use, easy to scale, with huge visibility into your network so you just see everything and you see it easily."

"We have seen a measurable decrease in the mean time when detecting and responding to threats."

More LogRhythm SIEM pros

"We use Security Onion for internal vulnerability assessment."

"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."

"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

"For me, room for improvement is the upgrade process."

"I work in a highly regulated industry. I know the product has compliance mechanisms, but being able to get more governance surrounding some of the compliance would be helpful."

"Some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity."

"NextGen SIEM has separate rules for AI, advanced intelligence, and MP rules - it would be better to have a centralized way to write the rules and create alarms."

"I have probably submitted half a dozen log parser requests, and I keep finding more stuff that we need to keep an eye on that doesn't have a definition in LogRhythm."

"The log source support is good, there's always room for improvement. One of the areas that LogRhythm's kind of pushing really hard right now is to integrate more cloud solutions, so your Office 365, your Azure, your AWS, making sure that those SaaS and other cloud platforms are getting the data you need into that platform."

"There is room for improvement with separate running sources or better integration."

"When we originally got LogRhythm, their tech support was fantastic, and I loved them. Now, we don't quite get as quick of a response. I've been disappointed in the more recent tech support. When you call in, they'll say that they will get you somebody, and you'll finally get someone who will contact you back a day or so later. Whereas before, I would get help right away."

More LogRhythm SIEM 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

"Look closely at the cost of licensing of other products. This should include setups and the need for support services. I did a RFQ to 2 other vendors before choosing this product."

"I would rate the tool's pricing around eight out of ten."

"The nice thing about LogRhythm is you can either use the agents, getting a certain number of agents with your license depending on how you want to go, and those agents do a lot of cool things, or you can use CIS Log host, then you have like an unlimited number of them."

"The support which allows more customized to the environment when we are deploying new systems is called Professional Service and is very expensive. The technical annual support and there is an annual fee."

"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."

"I think the tool is reasonably priced. There is a need to pay per year towards the licensing costs of the tool."

"In the context of our country, the price of this solution is too high."

"In comparison to the competition, they are more affordable. This allows us to do more with less."
