An easy-to-scale open-source solution used for monitoring events on devices
The area for improvement is a lot. When I started using it on our enterprise side, the issue we faced was, for example, if we were running at that time on AlienVault OSSIM v5.7.4. So, for some orders, we had to install some packages, and when we tried installing that package, some dependencies got upgraded to a new version. Now once that dependency got upgraded, the SQL, since you might be aware that OSSIM uses SQL database, now SQL and all the dependency in everything was not on the same version, and that caused the database to crash. The aforementioned area should be eased out by upgrading the patches and upgrading dependencies. This kind of thing is a disadvantage of OSSIM, and I would like them to work on this. But I have also raised service requests many times and gave it a push on the community section too. However, since it is a local source, they don't reply much over there. That is why I don't like to work on OSSIM because it is unpredictable. Once the storage goes above 50 percent, it starts behaving unpredictably. If you get stuck with a situation, then you need to drill a lockdown into that. Sometimes you get no luck. Then you have to just reimage the server with the new fresh OS of AlienVault. As for additional features, not much because if you move to the newer version, it is kind of getting more stable. But, to make my life easier, then I would say try to give more features. I know it's open source, so they also cannot provide me with more features. But still, if they can provide me with more features because right now it's becoming old. Right now, we are even moving from SIEM to Security Data Lake. So when we move to it, this will be literally outdated. No one can even expect anything out of it. The way security is moving, it will be outdated very soon. They have to also provide something new to keep this going for the future also.

Excels at performing regression and correlation on the data
ArcSight is a legacy technology, and many customers want AI-powered technologies integrated with it. That hasn't been done yet, but ArcSight needs to catch up with the newer solutions and technologies available in the market. It can't just rely on the legacy technology from 2010 or 2012. You can't run that in 2024. It's a legacy technology with its own limitations. Customers often face issues that other software or newer solutions can resolve easily. That's the main challenge we face from customers right now. So, the only concerns are that AI needs to be integrated and scalability improved. Those are the main areas to be improved.

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 case management, ease of configuration, and investigation."
"Asset discovery is good."
"The solution is free to use."
"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.""
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"Stable solution with good customer service support."
"There are many features that are good for clients who are looking for a good SIEM solution. They like the ease of creating a business that is effective and impressive."
"I value the event correlation of this product."
"I am satisfied with the solution's stability."
"ArcSight Enterprise Security Manager (ESM) is very cheap compared to other tools."
"​It is a vital tool for live monitoring and helps us to understand the traffic alerts of any major issue on the network, thereby reducing hacking attempts."
"It has absolutely improved the efficiency of our security team. We use it internally as well. It is such a powerful tool that our internal security team became a customer of our ArcSight managed service."
"I would rate the ease of use for new users an eight out of ten, with ten being easy to use. It is a good tool."
 

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"AlienVault OSSIM is costly."
"We need more dashboards and we need more customization for dashboards."
"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."
"I don't like to work on OSSIM because it is unpredictable."
"AlienVault OSSIM gives unwanted notifications."
"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."
"Customer service during the transition from HPE to Micro Focus was abysmal where it became disruptive to our service delivery."
"The centralized dashboard for the hybrid cloud environment needs to be more focused. It needs to be redefined because it's missing most of the information. It should be a little bit easy to use. Currently, integration with various applications and connectors is not that easy. Deployment is easy, but integration is not that easy. ArcSight also has a very high bandwidth consumption to pull the local servers. It should have some kind of better process or ability to transfer files from on-premises to the cloud, from the cloud to on-premises, and from a cloud to another cloud."
"I would like for them to integrate mobile devices. Integration or any kind of functionality which will act as a substitute for IBM so that we can really track our mobile devices as well as look at SIEM."
"There are several improvements that we would like to see, including: Building a system based on a log collection (SOC), a scenario for external encroachment, and Operator training."
"The stability of ArcSight Enterprise Security Manager (ESM) is not very robust."
"ArcSight ESM is not easy to use and it should be integrated with other tools that have infrastructure capabilities."
"The solution could be more stable."
"The initial setup could be more straightforward."
 

Pricing and Cost Advice

"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."
"OSSIM is 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."
"The solution is open source, so it's free to use."
"The tool's licensing costs are yearly."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"We're paying a fee for an MSSP, and the cost of the total cost of ArcSight ESM was approximately three to four million dollars a year. The price was less than similar solutions. We did not have additional fees."
"The solution is super expensive. At our organization size and license model, I think the price is average to what anyone else would charge us."
"The product licenses are inexpensive."
"The pricing is great compared to others."
"The pricing model is expensive compared to open-source alternatives."
"It's a good price, it's one of the cheaper solutions."
"HPE ArcSight pricing might be more expensive than other SIEM solutions, but in my opinion it has powerful features and great flexibility in developing complex use cases."
"We have a license to use this solution. The price of ArcSight Enterprise Security Manager is expensive."
