An open-source solution that provide good detection and more visibility
The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

Tool consistently aids in effective threat detection and monitoring but could benefit from improved log source management and resource optimization
One major area for improvement in LogRhythm SIEM is the lack of volume measurement capability in terms of storage. There is currently no way to determine how much data is being consumed in terms of gigabytes, terabytes, or petabytes from particular devices or environments. This information is crucial for planning future storage needs and scalability. 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. LogRhythm SIEM could improve by adding more default device support. While they have good default settings for devices such as Palo Alto firewalls, custom log sources often require extensive work. Increasing the number of supported devices with built-in policies and functionality would reduce the need for custom work. Competitive SIEM tools often provide more comprehensive coverage for various devices and vendors.
Mohammed Nadeem Rais - PeerSpot reviewer
The visibility and analytics from Securonix SIEM have become indispensable in identifying and stopping potential threats before they escalate.
The most valuable feature of Securonix Next-Gen SIEM is its advance analytics, flexibility and scalability. We ingest billions of logs without worrying about resource allocation. This makes it a robust and cost-effective solution for our needs. Its user entity and behavior analytics (UEBA) are also integral for detecting insider threats and lateral movements within the organization. These features help organizations strengthen their security posture, protect sensitive data, and maintain compliance with strict regulatory requirements.

Quotes from Members

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

Pros

"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"Network traffic analysis is highly efficient."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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.""
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The solution is very stable. Compared to Qradar and Splunk, it's very stable."
"The product is easy to use."
"Overall effectiveness is very good. I like how it is oriented to both analysts and technical support people. It's easily adopted by end users as much as by technologists."
"The most valuable features would be the automation, reporting, and the support."
"Our clients enjoy having one dashboard to monitor their environments in real time."
"I find LogRhythm's log management capabilities to be beneficial."
"In terms of security, LogRhythm NextGen SIEM is great."
"One of the main features that I like about LogRhythm NextGen SIEM is that there are a lot of pre-built pieces. Like with our AV, we didn't have to tell it how to read the logs; they already had it pre-made. So, we essentially just had to follow their guide to get the logs imported in and set up some rules for it. We've only had to manually create the parsing rules for a few of our vendors so that we could interpret the logs correctly. Most of them had already been pre-created for us."
"Technical support has always been helpful."
"The product is great for medium to large-scale organizations."
"The feature that is most valuable is the fact that it's an open platform, so it allows us to modify policies and tune policies as needed. There's also a feature called Data Insights which allows us to create different dashboards on specific things of interest for us."
"One of the valuable features of Securonix is the auto-incident creation, which was not available two or three years ago."
"One of the most valuable features it has is the thread chaining. One of the common issues that we always had was the number of anomalies that we used to get and the number of alerts that we used to get. But with this approach of thread chaining, we've found the false-positive rate has decreased very significantly. That was something that we never could have achieved before."
"We ingest billions of logs without worrying about resource allocation."
"The most valuable feature is that it works on user behavior and event rarities."
"The reporting in the Securonix Next-Gen SIEM is very good, and the dashboard is great."
"The big data security analytics platform, structured and unstructured data analytics, and user and entity behavior analytics provided by the product are probably the best in the industry."
"We can customize our use cases with the tools provided by Securonix. It is an excellent tool that can ingest data in different ways and is very flexible."
 

Cons

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The correlation engine needs to be improved."
"AlienVault OSSIM gives unwanted notifications."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"AlienVault OSSIM is costly."
"The documentation 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."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"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."
"The customer support system is time-consuming."
"There used to be the ability to create alarms based on message text that was included in LR Version 6.x that has been removed in LogRhythm 7.x, and on that, I would like to see it added back."
"I would like to see more integration with more products that are out there within the same security field."
"Scalability misses the mark sometimes, especially when you have an integrated disaster recovery built into the solution."
"Technical support could use a little work in the terms of responding back. The feedback that we received is they do need a little more staff."
"LogRhythm SIEM can improve its user interface. The current interface is quite complex and can be challenging to navigate. While it offers many valuable features, understanding how to access and utilize them efficiently takes time. Simplifying the client console's user interface would significantly enhance the user experience and make it more user-friendly."
"We're still struggling to get a real return on it and finding something that isn't false noise."
"It could be improved a little bit more for admin users. There should be more administrative options related to security for admin users. For example, for forensic purposes, the admin should be able to stop a specific user from erasing some information. I would be helpful in certain situations, such as during an internal fraud."
"One aspect that could be improved is the pricing of the product in Brazil."
"The passing and setup are quite complex at the beginning, making onboarding not smooth, which is an area that needs improvement."
"The analytics-driven approach for finding sophisticated threats and reducing false positives is positive and good, but the platform requires a more dynamic concept. Everything is a bit static."
"It seems to me that within Securonix there is no option for completely visualizing the types of sources or if there is any loss of logs. I've heard that they have an additional module to validate those types of cases, but in terms of the platform itself only, I can only see how often it sends data but not any specific detail."
"When dealing with a large amount of data, such as when firewall logs increase, queries sometimes crash or get stuck."
"Other than issues with the training, there have been issues with the encryption. There have also been issues with some of the reporting, minor glitches that they have fixed as they've gone along."
"We would like to see better integration with other products."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"The tool's licensing costs are yearly."
"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."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The product is inexpensive than other tools."
"We have seen a measurable decrease in the mean time to detect and respond to threats. As it comes out new features and new releases, the window is becoming a lot narrower because you can pivot a lot more with the data. Therefore, the new features and enhancements are reducing that."
"The solution has provided us with consistency and increased staff productivity through orchestrated automated work flows by at least 20 percent."
"Look for whatever will give you the most value. That's the main point. It is not one size fits all."
"I have seen a measurable decrease in the mean time to detect and respond to threats. We went from not detecting them to detecting them. We can actually pick up what is anomalous in our network now."
"If you don't have your staff, absolutely look into the co-pilot and factor that into your cost evaluation."
"LogRhythm's pricing and licensing is extremely competitive and it's one of the top three reasons we continue to invest in the platform."
"On a scale of one to ten, where one is low, and ten is high, I rate the pricing between six and seven."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"I rate the pricing an eight on a scale of one to ten, where one is cheap, and ten is very expensive. It is a pretty expensive tool."
"Its price is fine. We found it to be cheaper than LogRhythm, Exabeam, Splunk, as well as Elastic Security. A few months ago, when we were comparing Securonix with Elastic Security, we found Securonix to be cheaper than Elasticsearch. We were pretty surprised that Elastic Security is more expensive than Securonix because Elasticsearch is just starting, and it cannot compete with Securonix at this time. So, the pricing of Securonix is pretty good for now."
"A good thing about Securonix is that they don't charge by volume of data or number of devices... They charge by the number of employees, which is a much more predictable number for me, versus data. Our costs are in the $100,000 range over a three-year subscription."
"Compared to other brands it seems more affordable to us."
"I had heard that it was much cheaper than Splunk and some of the other tools, and they gave us a nice package with support. They accommodated the number of users and support very well."
"The solution's price is double the competitors."
"Its pricing is quite similar to others and is very competitive. The other solutions have different types of licensing, but when you do the math, it is competitive."
