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.

Some features such as device control, firewall management, and file analysis are standalone products that we need to purchase separately. If these features came out of the box within the product, it would be much more beneficial for us. Other providers such as SentinelOne include these features in their base product. We attended a CrowdStrike Falcon event where they discussed some shallow AI features, but we cannot see these in our panel yet. We work with different solutions such as Darktrace and SocRadar, where AI features are automatically displayed in our dashboards after release. However, for CrowdStrike Falcon, we cannot see these features.

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 this solution are the data correlation and vulnerability assessment."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The solution is free to use."
"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."
"The paid version of the solution has reporting and better scalability options."
"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."
"The initial setup is straightforward."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The most valuable features of CrowdStrike Falcon include Falcon Fusion workflows and endpoint detection capabilities."
"The 10 hours a week that we are freeing up from having to manage and monitor our AV solution has really allowed us to focus on other areas of the business. This has been a huge return on investment."
"The OverWatch is the most valuable feature to me. It's a 24x7 monitoring service, and when they see anything suspicious in my environment, they will investigate."
"The most valuable feature is that we don't need to re-image machines as much as we had to."
"The biggest advantage of this solution for my customers is that it is a single solution that fulfills most of their security concerns while being easy to manage."
"It helps to prevent unauthorized access or identity theft from external sites. If your identity is stolen, you can ban it."
"The most valuable features are the complete IPS and IDS."
"The ability to execute real-time response, or, that you can connect to the agent and see exactly what processes are operating, is the most important feature of this solution."
 

Cons

"The user interface could be improved."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The solution is not scalable."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"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."
"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."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The documentation could be improved."
"The solution needs to have integration with on-premises security devices and security facilities. That means all the security products, including the perimeter firewall, the DMZ."
"CrowdStrike Falcon by itself does not supply in-depth reporting."
"Basically, they don't cover legacy OS or applications. That's the only issue we're concerned about"
"Deployment in cloud environments is challenging. Another concern is CrowdStrike's GUI. It changes annually, making it hard to work and find options."
"We have had to open a case with the technical support to get some issues and bugs resolved."
"I would like to see the machine learning feature enhanced."
"I have worked with their technical support on several problems that were never fully resolved."
"They don't really have anything when it comes to scanning attachments."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"We are using the community version, which can be used for free."
"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 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."
"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 licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"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."
"While CrowdStrike Falcon offers significant security benefits, its high price point might make it prohibitively expensive for many small and medium-sized businesses, including companies like ours."
"CrowdStrike Falcon's price is good."
"The pricing and licensing are fairly good. It is definitely not a cheap product, but I have felt that it is worth the money that we spent. So, we have discussed it in the past, and were like, "Yes, it is probably pricier than some other solutions, but we also feel they really are the leader. We are very comfortable with their level of expertise. So, it's kind of worth the price that we pay.""
"I would like them to further reduce the price, because it is quite pricey at the moment."
"The more endpoints an organization adds the cheaper the cost."
"I'm not directly involved in sales, so I can't comment on the exact price, but I know the price decreases the higher the quantity we purchase."
"The cost is usually a challenge in the industry. I think we pay around sixty-eight dollars."
"In my opinion, the pricing of CrowdStrike Falcon seems aggressive."
