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.

Centralized environment supports big data while facing integration challenges
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

"I recommend it due to the experience of the people running it."
"With AlienVault you get everything in one box."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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 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 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," and the solution works well and allows me to have visibility into anomalous events."
"The product is easy 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."
"Our company very much sees the value in this and, as we move forward, we'll see even more value."
"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."
"The two major features of this product we extensively use are the UEBA capability and the multi-tenant approach with the centralized data logs system. Customers are very happy with these features."
"Securonix Next-Gen helps us detect advanced threats faster and gives us lower response times."
"In the beginning, we were hesitant to use a new tool, but it soon became our go-to tool for checking and verifying any issues."
"The detection of threats and reduction of false positive alarms as compared to other solutions are valuable features. It has improved threat detection response and reduced a lot of noise from false positives as compared to our previous SIEM solutions."
"The customizability of the tool is valuable. We are able to customize the use cases and create them easily without a large amount of Securonix assistance. It's very flexible. We do not have to rely on Professional Services to modify or create a new use case."
"I find customer service to be very good."
 

Cons

"We need more dashboards and we need more customization for dashboards."
"It's so hard to configure and explore something new on it."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"I don't like to work on OSSIM because it is unpredictable."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The biggest thing I always complain about is that the user intake is a very old version."
"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."
"Securonix could open up information regarding the indicators of compromise or cyber-threat intelligence databases that they use."
"When they did upgrades or applied patches, sometimes, there was downtime, which required the backfill of data. There were times when we had to reach out and get a lot of things validated."
"In terms of improvements, SIEM could have better integration with other technologies. Additionally, it might benefit from integration with other sources, such as firewalls."
"SIEM could have better integration with other technologies."
"Parsing needs to be improved. Every time we integrate a new, specific data source, we face a lot of problems in parsing, even for the old data source."
"Sometimes, it can become a little overwhelming."
"We would like a little more face-to-face training."
"One of the things they can improve on a little bit is the usability side, to make some things simpler... The tool does have a lot of knobs, you can turn a lot of things on and off and you can change things. Sometimes, it can become a little overwhelming. They should remove some confirmation options and make it simpler for the less mature customers and people who are still trying to grasp it."
 

Pricing and Cost Advice

"OSSIM is free."
"AlienVault OSSIM is free."
"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 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 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 an open-source solution."
"The tool's licensing costs are yearly."
"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."
"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."
"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."
"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."
"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."
"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."
"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."
