Featured Reviews

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 most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"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 solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The initial setup is straightforward."
"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 solution is free to use."
"SNYPR has a bundle of features. It has the UEBA feature that tells you about the behavior of a person or entity. In the tool itself, there is an incident management feature, which is definitely valuable."
"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 solution is time-saving, particularly in the long run after it is deployed, enabling us to get value promptly."
"One of the valuable features of Securonix is the auto-incident creation, which was not available two or three years ago."
"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 feature that is most valuable is the fact that it's an open platform, so it allows us to modify policies and tune policies as needed. There's also a feature called Data Insights which allows us to create different dashboards on specific things of interest for us."
"What I like most is that the threat models and risk scoring are very accurate and very helpful to the analysts on my team. They help highlight the most important things for them to look at."
"The big data security analytics platform, structured and unstructured data analytics, and user and entity behavior analytics provided by the product are probably the best in the industry."
 

Cons

"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."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"AlienVault OSSIM is costly."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM gives unwanted notifications."
"The user interface could be improved."
"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."
"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."
"We have compliance needs. We have investigation needs. And we have situations where an analyst needs to look at threats. These three things require a different view of how they look at the threats. What would be good is to have Securonix create three different views of their Security Command Center so that, depending on the persona of the person logging in, they'd get the relevant data they need and not see everything."
"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."
"When dealing with a large amount of data, such as when firewall logs increase, queries sometimes crash or get stuck."
"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."
"The dashboards in Securonix Next-Gen SIEM need more customization and informational capabilities."
"SIEM could have better integration with other technologies."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"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."
"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."
"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."
"The tool's licensing costs are yearly."
"We are using the community version, which can be used for free."
"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."
"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 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 solution's price is double the competitors."
"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."
"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."
"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."
"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."
"Licensing is based on events per second (EPS), costing between $50 to $60 per EPS."
