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

"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"I recommend it due to the experience of the people running it."
"AlienVault OSSIM's GUI is very user-friendly."
"The product is easy to use."
"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."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."
"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."
"The customization of reporting rules, reporting configuration, and alerting configuration are good."
 

Cons

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The incidence reporting could be better."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"I don't like to work on OSSIM because it is unpredictable."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"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."
"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."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"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."
"I would like Gurucul to identify the use cases that have already been reviewed by someone when detection occurs."
 

Pricing and Cost Advice

"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."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"We are using the community version, which can be used for 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."
"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 tool's licensing costs are yearly."
"The pricing is exceptionally good"
