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.

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

"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"Better than other SIEM solutions because almost everything can be integrated."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"AlienVault OSSIM's GUI is very user-friendly."
"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."
"Asset discovery is good."
"What I like about this product, is that it is a fully-fledged solution."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"The customization of reporting rules, reporting configuration, and alerting configuration are good."
"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."
"Gurucul Next Gen SIEM stands out for its user-friendliness, making it accessible to business users."
 

Cons

"The user interface could be improved."
"The user interface needs to be friendlier across the board."
"I would advise others to not implement it for any enterprise-level organization."
"Sometimes it takes very long for your issue to get resolved."
"ArcSight works better than AlienVault right now."
"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 initial setup was not so easy, partly because the documentation was not up to date."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"I would like Gurucul to identify the use cases that have already been reviewed by someone when detection occurs."
"The user interface could be made simpler."
"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."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is an open-source solution."
"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 OSSIM is 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."
"We are using the community version, which can be used for free."
"The pricing is exceptionally good"
