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.

User-friendly interface has improved threat detection through real-time analytics and AI advancements
They are very updated. Their customer responses are great, and they keep using the new AI tools to keep themselves at the edge of the game. This is very helpful because there are many false positives which keep cropping up, and one of the things that Securonix Next-Gen SIEM does very well is ensuring they don't give attention to false positives. They don't take attention away from the real problems and reduce a lot of noise. We look forward to more developments from Securonix Next-Gen SIEM in terms of their service turnaround times and staying connected with customers.

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 majorly used for threat detection of the agents on servers and endpoints."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"The paid version of the solution has reporting and better scalability options."
"The product is easy to use."
"With AlienVault you get everything in one box."
"Technical support is excellent; they are very helpful and responsive."
"The solution is free to use."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"The software includes user behavior interactions, dashboards, and training capabilities."
"We can now process more data in 20 minutes, it has improved analyst efficiency by 30%, and we haven't experienced any data loss, which is good."
"The most valuable feature is what Securonix calls enrichment. Securonix is very powerful because of all the data it can process and automatically enrich. The actionable intelligence it provides is one of its benefits, due to the processing capacity it has."
"The machine-learning algorithms are the most valuable feature because they're able to identify the 'needle in the haystack.'"
"The second feature is that within the SNYPR product there is a functionality called Spotter. We use that for link analysis diagrams and to run the stats command. That's extremely useful because it replaces a tedious, manual process we used to use, using Microsoft Excel and a couple of other methods, to bring data together."
"Most of our clients are very happy with the solution."
"Securonix Next-Gen helps us detect advanced threats faster and gives us lower response times."
"With UEBA being a relatively new space when we looked at it close to two years ago, we were concerned about how well it worked and whether they were truly behavioral-based rules or if that was just marketing terminology for the "latest greatest system," but it exceeds what our initial expectations were for being able to detect different cyber threats."
 

Cons

"AlienVault OSSIM is costly."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The solution is not scalable."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"It takes some time. It does not give me a prompt response for any such [malicious] traffic. It takes time to get that alert from the AlienVault system."
"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."
"Lacking in depth of reporting."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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."
"When dealing with a large amount of data, such as when firewall logs increase, queries sometimes crash or get stuck."
"There is room for improvement in the product's integration with ServiceNow and in the reporting features."
"The technical support of the solution is an area with shortcomings and needs improvement."
"It could be improved a little bit more for admin users."
"Securonix Next-Gen SIEM's deployment is complex and you need a team to do it."
"Six months ago, if someone asked me about the support, I would say, "Not good.""
"We look forward to more developments from Securonix Next-Gen SIEM in terms of their service turnaround times and staying connected with customers."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"OSSIM is 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."
"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."
"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."
"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."
"AlienVault OSSIM is free."
"Compared to other known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"Compared to other brands it seems more affordable to us."
"We have a license from our 5.0, so that license just continued. We paid them the extra cloud-hosting costs for a year which were about $300,000."
"The solution's price is double the competitors."
"The pricing is good, but by adding more things, the licensing becomes more complex because an EPS license fluctuates a lot. This licensing concept is going to be problematic in the long run."
"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."
"The pricing is fine compared to the market but I think that at some point the competitors will catch up on price."
