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.

I don't have specific information on whether it was purchased on the AWS marketplace or somewhere else. I am working with Dynatrace Operator. I am also working with Algosec, Alluvio, CrowdStrike, Firemon, Gigamon Deep Observability Pipeline, and other solutions. I think it's a good tool, and I am satisfied with it. We have not stored cloud workloads with Gigamon Deep Observability Pipeline yet; we are still on-premises. The technical support takes about one to two hours to respond, which is acceptable. I am satisfied with the scalability of the product. The interface is good.

Quotes from Members

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

Pros

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"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 solution is free to use."
"The initial setup was straightforward. I didn't have any problems."
"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"Better than other SIEM solutions because almost everything can be integrated."
"The initial setup is straightforward."
"The most valuable feature is the logging capability."
"The most valuable feature is NetFlow."
"It has high stability."
"We use Gigamon for network visibility."
"The tool's most valuable feature is the encryption feature. From a security perspective, the solution hasn't significantly strengthened our security posture. However, it has greatly improved performance by streamlining encryption processes and avoiding encryption at multiple layers. This has also simplified troubleshooting, as we can whitelist certain processes."
"The Pipeline's Comprehensive Insights into data flows have helped improve operational efficiency and security."
"The most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"The solution is straightforward to set up."
"It is a good product. It provides network visibility, which is important. Gigamon can bring some optimizations to my network. It is helpful for security inspection, and it makes my firewall work fast because my firewall doesn't have to do the inspection of the SSL connections, for example."
 

Cons

"The solution is not scalable."
"We need more dashboards and we need more customization for dashboards."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"It's so hard to configure and explore something new on it."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Lacking in depth of reporting."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The security should be improved."
"The security should be improved."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"They should increase the solution's cluster capacity."
"The Gigamon Deep Observability Pipeline should have a feature showing the traffic flow within its platform. Currently, customers have to use separate tools for monitoring, which is inconvenient. If it had its visibility feature, it would make monitoring easier and more complete without needing extra tools."
"Gigamon Deep Observability Pipeline needs to improve its performance. I face issues with performance because we use SPAN, and the SPAN traffic is not good."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"The graphical user interface could be improved."
 

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."
"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."
"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."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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 highly-priced."
"The solution's price is reasonable."
"I would rate the solution as expensive, around an eight or nine out of ten. There are other competitive solutions available."
