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.
Ansar Monideen - PeerSpot reviewer
Provides almost all the SIEM features offered by the leaders at a low cost
Gurucul's data enrichment could be improved. As a security professional, I want to consolidate all these log sources and data to the user, entity, or resource. More advancements are required, especially in enriching security data or attack response. I would like to see more improvements there. The documentation could also be better. Every user and resource has a timeline that lists all the events so we can analyze that particular system and what is happening. We would like to have an option where we can only list the confirmed security threat-related activities for a particular user rather than all activities. This way, we can see what kind of risk is reported for this user and be able to monitor them better.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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 most valuable feature is the logging capability."
"AlienVault OSSIM's GUI is very user-friendly."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"Better than other SIEM solutions because almost everything can be integrated."
"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."
"I like the amount of customization we can do with Gurucul. We can customize each solution and evaluate it. We can investigate the alerts that it creates and fine-tune them to ensure that whatever is reported has some risk."
"The customization of reporting rules, reporting configuration, and alerting configuration are good."
"Gurucul Next Gen SIEM stands out for its user-friendliness, making it accessible to business users."
 

Cons

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"I don't like to work on OSSIM because it is unpredictable."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The price of this solution is very high and it could be cheaper."
"The user interface could be improved."
"They can add more compliance templates."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"I would like Gurucul to identify the use cases that have already been reviewed by someone when detection occurs."
"Gurucul's data enrichment could be improved. As a security professional, I want to consolidate all these log sources and data to the user, entity, or resource. More advancements are required, especially in enriching security data or attack response. I would like to see more improvements there."
"The user interface could be made simpler."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"We are using the community version, which can be used for 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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"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."
"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."
"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 pricing is exceptionally good"
