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 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."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"The initial setup was straightforward."
"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."
"I have deployed it widely because I find that it gives value for money."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"The detection and response console is the most valuable feature."
"CrowdStrike Falcon's scalability is good. We have thousands of students using this solution."
"The machine learning behavior for anomaly detection is a valuable feature. It helps identify any suspicious or unusual activities within the system."
"The detection is very reliable. Also, OverWatch is a great feature."
"CrowdStrike has a much lower rate of false positives than Cylance and the dashboard makes it easier to use."
"The most beneficial part is the active response capability of the product."
"The flexibility and always-on protection that is provided by a cloud-based solution are important to us; the cloud is everywhere, so with the agent on the laptop, wherever the user may go, including home, office, or traveling, it's protected 24x7, all the time."
"It's given me a level of confidence that my network is secure."
 

Cons

"ArcSight works better than AlienVault right now."
"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."
"It's so hard to configure and explore something new on it."
"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."
"I would advise others to not implement it for any enterprise-level organization."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"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."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"One thing that is not yet available is attack simulation."
"The UI is not efficient."
"CrowdStrike should provide better visibility in its reporting. There should be more forensic details about detected threats."
"CrowdStrike Falcon could improve the logs by making them free to the API."
"The solution could improve by providing more types of reports because it's in the detection span you cannot re-export anything."
"The dashboard area must be improved. We have integration with Splunk, and we are creating a dashboard there. Their dashboard area must be up to date. It should have more details and more options to create the reports and things like that."
"We'd like to see more integration capabilities."
"CrowdStrike Falcon could improve by having an easier way to search and use the interface for extracting queries from the data."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"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."
"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."
"OSSIM is free."
"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."
"We are using the community version, which can be used for 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."
"CrowdStrike Falcon offers excellent value for the money for our organization, particularly given our lean IT team."
"Crowdstrike Falcon is relatively cheap."
"All I can say about the licensing cost is that it's negotiable."
"When it comes to licensing, customers can choose a bundle or select licences based on the specific features they would like access to. This solution comes with premium pricing. It is approximately 20 to 30% more expensive than competing solutions."
"There are approximately a hundred different modules you have to purchase, depending on what you want to do. I have most of the modules. How it works is you buy the portfolio, you have to decide all the components you want in it, and then they price out a bundle for you. I have almost all of the package features in my bundle. You only need to pay for the modules you want."
"The more endpoints an organization adds the cheaper the cost."
"This solution offers annual subscriptions. The pricing for this solution could be reduced."
"We bought a very small number of licenses, then ran it for a year. We bought a 100 licenses for a year, so we didn't actually do a proof of concept. We just bought them. Then, the next year, we bought 10,000 licenses."
