HarshBhardiya - PeerSpot reviewer
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.
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

"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."
"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."
"Network traffic analysis is highly efficient."
"AlienVault OSSIM's GUI is very user-friendly."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"Asset discovery is good."
"The solution has proven to be stable so far...The solution is easy to scale up."
"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 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."
"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."
"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 machine-learning algorithms are the most valuable feature because they're able to identify the 'needle in the haystack.'"
"The solution is stable and scalable."
"The AI capabilities enhance threat detection."
 

Cons

"It's so hard to configure and explore something new on it."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The incidence reporting could be better."
"I don't like to work on OSSIM because it is unpredictable."
"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."
"We need more dashboards and we need more customization for dashboards."
"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."
"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."
"We would like a little more face-to-face training. Securonix has several tutorials on its website, but we want there to be a person in Colombia who does training or workshops to give us a better understanding of the platform."
"The passing and setup are quite complex at the beginning, making onboarding not smooth, which is an area that needs improvement."
"There is slight room for improvement in terms of the initial deployment. What I see is that Securonix is more focused on their product. They are expanding, in a big way, the number of customers. So there has to be a number of dedicated teams to jump on and speed up the deployment process."
"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."
"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."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"We are using the community version, which can be used for free."
"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."
"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."
"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."
"Compared to other known brands in the industry, the overall cost of the licenses is a bit higher than what customers expect."
"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."
"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."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
"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."
"The pricing is fine compared to the market but I think that at some point the competitors will catch up on price."
"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."
"Compared to other brands it seems more affordable to us."
