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

"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 AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"I recommend it due to the experience of the people running it."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"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," and the solution works well and allows me to have visibility into anomalous events."
"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 main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"Lacking in depth of reporting."
"The documentation could be improved."
"The user interface needs to be friendlier across the board."
"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."
"I would like Gurucul to identify the use cases that have already been reviewed by someone when detection occurs."
 

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