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 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."
"The initial setup is straightforward."
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"What I like about this product, is that it is a fully-fledged solution."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"The AI capabilities enhance threat detection."
"I was looking for software as a service rather than having issues with managing hardware, upgrades, updates. I was trying to step away from that. Those were the key factors when looking at Securonix as a full-feature SIEM with next-generation capabilities available."
"We can select the resource group name or functionality directly of which type of security tool logs we want. We don't need to write the query for that; we just have to select."
"The most valuable feature is that it works on user behavior and event rarities."
"It is an excellent tool that helps us optimize threat-hunting operations, detect intrusive events on the network, and respond to security incidents."
"The solution has proven to be stable so far...The solution is easy to scale up."
"The product reduced our investigation times by about 85 percent."
"The scalability is one of the remarkable qualities of this product, which makes it very effective, especially when we are dealing with substantial data volumes in the cloud."
 

Cons

"Sometimes it takes very long for your issue to get resolved."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"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."
"The price of this solution is very high and it could be cheaper."
"The biggest thing I always complain about is that the user intake is a very old version."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The incidence reporting could be better."
"We would like to see better integration with other products."
"A helpful feature would be an event export. A way to create more substantial summary reports would be nice."
"Sometimes, it can become a little overwhelming."
"The passing and setup are quite complex at the beginning, making onboarding not smooth, which is an area that needs improvement."
"It could be improved a little bit more for admin users."
"The customization in Securonix Next-Gen SIEM is more difficult compared to other solutions. At the admin level, we have many challenges where log parsing is causing issues and compatibility is not present."
"The incident response area should be improved."
"The UX could be simpler."
 

Pricing and Cost Advice

"OSSIM is free."
"AlienVault OSSIM is an open-source solution."
"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."
"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 solution is open source, so it's free to use."
"AlienVault 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."
"We went in on a three-year agreement which has an annual licensing fee, based upon the number of people that we're monitoring. There have not been any additional costs to the standard licensing fees."
"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 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."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"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."
"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."
"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."
