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.

The customization in Securonix Next-Gen SIEM is more difficult compared to other solutions. At the operation level, we are not facing many challenges with automating things using Securonix Next-Gen SIEM, but at the admin level, we have many challenges where log parsing is causing issues and compatibility is not present. The primary technology challenge we have is not at the security tools level. For example, firewall Cisco and others are capable. However, specific to product, for SAP, we are using certain products, and developing custom connectors for each product, especially the internal applications, is difficult, and Securonix Next-Gen SIEM is not up to the mark.

Quotes from Members

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

Pros

"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"AlienVault OSSIM's GUI is very user-friendly."
"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."
"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 initial setup is straightforward."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"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 solution is free to use."
"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."
"I rate the technical support a nine out of ten. They're friendly. Whenever we have a P1 issue, we write an email and our issue is resolved in one or two hours."
"When we were looking for products for our security monitoring needs, our biggest requirement was that we wanted something based on machine-learning and analytics. If you go with rules, it can raise a lot of noise. Securonix, with its UEBA capability, had the best analytics use-cases."
"The solution's AI features reduce the need for manual analysis and help in decision-making. It displays the report in seconds. It saves my resources three to four hours of work."
"Risk scoring was nice. We could exactly see which user had the highest risk score, and then we could pick it up and work on it."
"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."
"The solution has proven to be stable so far...The solution is easy to scale up."
"The feature that I have found most valuable is their analytics platform where they have the open security data-link, which they introduced. This is typically different from the other vendors."
 

Cons

"Sometimes technical issues take very long to get resolved."
"We need more dashboards and we need more customization for dashboards."
"The solution needs more integration with cyber intelligence systems."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"GUI could be improved."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"When dealing with a large amount of data, such as when firewall logs increase, queries sometimes crash or get stuck."
"We look forward to more developments from Securonix Next-Gen SIEM in terms of their service turnaround times and staying connected with customers."
"The passing and setup are quite complex at the beginning, making onboarding not smooth, which is an area that needs improvement."
"Sometimes, the injectors lag and are not loading. It would be nice if that could be improved."
"The dashboards in Securonix Next-Gen SIEM need more customization and informational capabilities."
"The passing and setup are quite complex at the beginning, making onboarding not smooth, which is an area that needs improvement."
"There is room for improvement in the product's integration with ServiceNow and in the reporting features."
"Securonix implements risk scores based on different policies that are triggered. We've seen some challenges with the risk scores and how they trigger. These are things that Securonix has recognized and they've been working with us to help improve things."
 

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"The price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"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."
"We are using the community version, which can be used for free."
"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."
"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."
"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."
"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."
"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."
"We have an annual license. We pay $200,000 for the base licensing and we pay another $50,000 for the software as a service."
