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.

It is a stable solution, but they should make the user interface easier to understand

The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.

Quotes from Members

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

Pros

"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 very stable, and compared to QRadar and Splunk, it's very stable."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."

"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"

"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.""

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."

"With AlienVault you get everything in one box."

More AlienVault OSSIM pros

"Their technical support responds quickly and are knowledgable."

"The most valuable feature is the ability to write rules and triggers for network communication, and then being able to investigate based on that."

"NetWitness Platform is valuable for creating rules that the solution must detect."

"The most valuable feature is the security that it provides."

"It gives the ability to investigate into network traffic in the Net and the organization what we couldn't do before."

"Overall, I feel that the product is very good and my biggest complaint is about their support."

"The development of use cases on the SSA console is quite user friendly, which means that the security analyst or the researcher does not have to learn another language."

"The solution is really scalable for the high-end power, enterprise customer."

More NetWitness Platform pros

Cons

"I would advise others to not implement it for any enterprise-level organization."

"Sometimes it takes very long for your issue to get resolved."

"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."

"The correlation engine needs to be improved."

"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."

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"The solution is not scalable."

"Lacking in depth of reporting."

More AlienVault OSSIM cons

"If we have the ability to run a dynamic analysis through malware in the same suite, it would be great to have a sandbox solution to analyze malware through dynamic analysis."

"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."

"I cannot say that the solution was stable because it tended to crash."

"Technical support could be improved."

"The product's licensing models are complex to understand. This particular area needs improvement."

"The initial setup is very complex and should be simplified."

"It is overly complicated. It has taken years to implement and the return on investment just isn't there."

More NetWitness Platform cons

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."

"AlienVault OSSIM is free."

"We are using the community version, which can be used for free."

"The solution is open source, so it's free to use."

"OSSIM is free."

"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."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"The product is expensive."

"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."

"It’s cheaper to run virtual machines in a VMware environment."

"The licenses are good but the cost is very expensive."

"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."

"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."

"This is a pricey solution; it's not cheap."

"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
