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.

A solid SIEM solution that should improve technical support and online resources to be easier to use
A big problem with the product is that we don't have much professional experience in Israel installing, implementing, and integrating this product. There is not enough of a knowledge base. There is no support for this product in this country, so problems have to be resolved through global technical teams. We like to work locally because of the language, and when the product is only supported outside the country, it's a little difficult to implement and use this product. Moreover, AI is something that must be added immediately. Artificial intelligence is a part of the competitors' products, and it's not been implemented for us.

Quotes from Members

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

Pros

"The initial setup is 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."
"The paid version of the solution has reporting and better scalability options."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"Network traffic analysis is highly efficient."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"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."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"Incident management is its most valuable feature."
"The most valuable feature is the correlation, as it can report in real-time and monitor the management."
"The development of use cases on the SSA console is quite user friendly. This means that the security analyst or the researcher does not have to learn another language."
"It's quite economical compared to other solutions in the market."
"The product's initial setup phase was not at all difficult."
"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."
 

Cons

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"The correlation engine needs to be improved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"The solution is not scalable."
"I don't like to work on OSSIM because it is unpredictable."
"Sometimes it takes very long for your issue to get resolved."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"An area for improvement would be better automation and more inbuilt use cases."
"It is not so easy to customize this product."
"Sometimes, it gives me static when integrating Windows-based systems. It should produce a precise log of sorts as to where the problem is. For example, a few days ago because of the McAfee application firewall, I couldn't get access to the particular Windows machine. So, my team and I had to figure out by ourselves that there was a virus responsible for the obstacle. This solution should trigger a meaningful log or message indicating the reason the user or implementer can't get into the machine."
"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"We encountered stability issues in the earlier versions, and much fewer in the newer versions."
"The implementation needs assistance."
"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 product's licensing models are complex to understand. This particular area needs improvement."
 

Pricing and Cost Advice

"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."
"We are using the community version, which can be used for free."
"The solution is open source, so it's free to use."
"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 an open-source solution."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"This is a pricey solution; it's not cheap."
"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 tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"It provides tools to assist in selecting the appropriate license and usage scenarios."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"It is cheap."
"The product is expensive."
"Our license is for one year."
