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

"Network traffic analysis is highly efficient."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"The product is easy to use."
"Technical support is excellent; they are very helpful and responsive."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"What I like about this product, is that it is a fully-fledged solution."
"AlienVault OSSIM's GUI is very user-friendly."
"The initial setup is straightforward."
"Technical support is very good; they try to resolve issues with the proper SLAs which are defined by them and they understand the client's requirements as well as the client's infrastructure in a better manner."
"Overall, I feel that the product is very good and my biggest complaint is about their support."
"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"Offers a good wireless feature."
"Integration is exceedingly minimal, since its project development is much easier than that of LogRythm or IBM."
"RSA NetWitness is a SIEM and real-time network traffic solution that collects logs and packets, applies a set of alerting, reporting, and analysis rules on them, and thus provides the enterprise with full visibility of the networks and activities of the systems."
"What we are mainly using are the RSA concentrator, RSA Decoder, Archiver, Broker, and Log Decoder."
"Prior to implementing the solution, the customers had no visibility of their assets, however, after adopting the solution, they have gained complete visibility over all their assets, including a comprehensive understanding of the network and attack symptoms."
 

Cons

"The user interface could be improved."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The initial setup was not so easy, partly because the documentation was not up to date."
"Lacking in depth of reporting."
"The price of this solution is very high and it could be cheaper."
"We need more dashboards and we need more customization for dashboards."
"It is overly complicated. It has taken years to implement and the return on investment just isn't there."
"RSA NetWitness Logs and Packets can improve the threat level aspect, it is lacking compared to other solutions."
"The tool's integration capability isn't so great."
"Its technical support could be better."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"Advance monitoring and alerting feature is not stable (Event Stream Analysis)."
"The initial setup is complex. There are other solutions that are easier to implement."
"One thing to be improved in NetWitness is the capability to correlate event logs in a general sense."
 

Pricing and Cost Advice

"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 free."
"The solution is open source, so it's free to use."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"AlienVault OSSIM is an open-source solution."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"The licenses are good but the cost is very expensive."
"Compared to the competition, the is price is not that high."
"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."
"The product is expensive."
"This is a pricey solution; it's not cheap."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
