Independent Contractor at a comms service provider with 5,001-10,000 employees
Enables cost-effective security management for small businesses
Scaling for USM is always challenging for any product unless it is purpose-built or overbuilt at the front end. They will use Palo Alto and its competitors, and LevelBlue will manage that implementation. The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale. By pushing it to a cloud-based system, they've largely alleviated scale issues. It's native in Amazon but will also run in Azure. They have worked with cloud service providers to offer enough throughput at a cost reasonable for a corporation. Scaling was their biggest problem, and they've largely conquered those issues.

Provides strong detection capabilities but requires improvements in parsing and stability
I cannot think of any specific features that LogRhythm SIEM can improve upon since it supports a wide variety of major vendors. However, they need to improve their parsing techniques; the tool should understand various devices and present data in a human-readable format. For example, if a personal Android mobile needs to be integrated, LogRhythm SIEM should be able to parse that data effectively. They also need to improve their database of supported devices to cover smaller vendors alongside the major players, allowing for better global reach and usability. I have noticed some problems with parsing errors, event mismatches, and data mismatching, so ensuring accurate parsing and continuous improvement according to device updates are my basic expectations as a detection engineer.

Quotes from Members

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

Pros

"The product is easy to use."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"Network traffic analysis is highly efficient."
"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""
"You can customize the dashboards as well as the reporting."
"Better than other SIEM solutions because almost everything can be integrated."
"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"File Integrity Monitoring is really valuable because we have it set up on our core assets. This is one of the key features that I utilize. We also use it quite a lot for event management to do reporting."
"It supports most standard log sources."
"As a healthcare company, what we use it for is compliance, then to protect our data from exaltation."
"We have to be able to show the evidence, and LogRhythm does a great job of putting it forward and making it easy to create reports with nice looking dashboards, which show off what we are doing as a security program."
"LogRhythm's correlation capabilities (part of the AIE component) is much better than Splunk's, and the solution as a whole is generally cheaper and easier to implement than ArcSight."
"The user interface is pretty good compared to other SIEM tools."
"The LogRhythm AIE (Advanced Intelligence Engine) is very good at alerting my SOC to events of interest and potential security issues without flooding my team with noise."
"LogRhythm NextGen SIEM is customizable, simple to manage, and there are many features. The solution does not require an expert to be able to use it, anyone can use it."
 

Cons

"The documentation could be improved."
"We need more dashboards and we need more customization for dashboards."
"AlienVault OSSIM is costly."
"The price of this solution is very high and it could be cheaper."
"The solution needs more integration with cyber intelligence systems."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"GUI could be improved."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"Scalability-wise, it's not that great."
"I would like it to do a lot of the automation (which I still need to learn more about), because I am essentially a one man shop doing all the jobs. I'd like for it to be able to do more for me."
"The system monitor (collector) agent has issues with resource consumption. Even when not actively collecting data, the agent continues to consume significant CPU and memory resources, which can be particularly problematic for small business environments with limited resources."
"The customer support system is time-consuming."
"LogRhythm NextGen SIEM is currently based only on the Windows platform. This means that some of our customers have to purchase a Windows license elsewhere. If LogRhythm can move to a Linux platform or a proprietary platform, it would be very helpful."
"The security playbook could be pre-defined and available to other analysts with similar security issues."
"Some of my customers have a very large need but refuse to go with LogRhythm SIEM due to its complexity and high resource intensity."
"I don't think the cloud model in LogRhythm is developed enough."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"AlienVault OSSIM is an open-source solution."
"I used the paid version of the tool and found it to be expensive. It has been a while since I changed to Securonix. I will have to check whether AlienVault charges per device, user, or log."
"AlienVault pricing is the best. Whatever cost you are paying, you are getting a return on every penny... It's not like your IBM, your QRadar, or Splunk, where the cost is too high."
"AlienVault OSSIM is expensive compared to its competitors."
"We are using a free version of the solution. If you purchase a license there are more features available but the price is a little high. The solution should be cheaper to allow more customers to be able to afford it."
"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 pricing is very reasonable and accessible compared to other products in the market but I am not very sure about the exact licensing cost per year for our company."
"It is a very cost-effective solution."
"The product is inexpensive than other tools."
"When it comes time to renew, they say, "This is what you are using. This is what we can do for you." So, they work with you on pricing."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"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."
"I give the price a six out of ten."
