Enables cost-effective security management for small businesses
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.

Cloud-native security has improved real-time threat detection and streamlined daily operations
While CrowdStrike Falcon is strong overall, there are a few areas where it could be improved. First, the user interface can be a bit complex for new users. Sometimes, navigating through different sections and understanding detailed alerts takes time, especially for teams without deep security expertise. The cost is also something to consider, as the features and additional modules can increase pricing, which may be a challenge for smaller teams. Additionally, some integrations with simpler reporting would be helpful. The onboarding process for new users is a bit challenging for beginners to understand all features and workflows in the product. More simplified documentation, step-by-step guides, and real-world examples could help new users get comfortable faster. A structured onboarding or basic training module would be very useful for teams who are new to endpoint security tools. In addition, having more in-product guidance and tooltips within the dashboard could make navigation easier and reduce the learning curve. Overall, improving training resources and onboarding support would make the platform more user-friendly, especially for new users.

Quotes from Members

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

Pros

"The product is majorly used for threat detection of the agents on servers and endpoints."
"Network traffic analysis is highly efficient."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"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."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"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 has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"Falcon's best feature is its detection and blocking of threats."
"The detection and response console is the most valuable feature."
"All the features are beneficial."
"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."
"It seems to do a pretty good job of protecting the host. It offers good insights that it gives you when it has a detection. It's pretty incredible."
"Falcon has the capacity to identify potential problems quickly. The administrator can deploy the agent, and the users cannot change it. This assures you that the agent remains on this device. Also, the agent can act preemptively to provide alerts about potential problems."
"We compared multiple solutions in EDR and out of them, CrowdStrike gave the most features and value for money."
 

Cons

"The biggest thing I always complain about is that the user intake is a very old version."
"AlienVault OSSIM is costly."
"ArcSight works better than AlienVault right now."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"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."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"There are a lot of open integrations, but they are external factors that cause dependencies on the integrator, not really on CrowdStrike, so it's a bit of a challenge as there is no comprehensive solution."
"We have had to open a case with the technical support to get some issues and bugs resolved, but they were resolved relatively quickly."
"The portal can be clunky to navigate at times and has room for improvement."
"The content-filtering features for children could be improved. We have young grandchildren aged 12 and 8. My daughter, their mother, wants to keep them from getting in trouble on the net. She looked at all these other solutions from Google, Microsoft, etc., and she couldn't figure out how to make any of those work. I told her that I bet CrowdStrike could handle this. Sure enough, CrowdStrike can do exactly that. It's the same solution that the Defense Department gets. It works, but it's a little complicated to implement. It could be simpler to set the policies."
"The installation process for this software needs to be simplified."
"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."
"The tool is more expensive than other products in the market."
"As the company has grown, the technical support has felt less personal."
 

Pricing and Cost Advice

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"OSSIM is free."
"AlienVault OSSIM is an open-source solution."
"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."
"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."
"AlienVault OSSIM is 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."
"We pay between $30-50 per user for a yearly license, which is more expensive than SentinelOne or Bitdefender. However, CrowdStrike gives better value for money."
"We are at about $60,000 per year."
"This solution has a very competitive price."
"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.""
"The price of CrowdStrike Falcon is expensive and should be reduced."
"The pricing will depend upon your volume of usage."
"There are three to four licensing models available to choose from for CrowdStrike Falcon. The price of CrowdStrike Falcon depends on the distributor and the reseller partner. The price we received was good."
"The pricing and licensing are reasonable. I don't think we are getting charged more than what it is worth. It is fair, but I do not like how it is a la carte. I realize they do that so other organizations can buy and get the agent, getting it cheaper than you could otherwise. However, if you want the main core package, which has all the main features with the exception of maybe the multi-cloud protections, that can get pricier for an organization. So, you have to pick and choose what you want. I do not care for a la carte pricing."
