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.

"With AlienVault you get everything in one box."
"Network traffic analysis is highly efficient."
"Better than other SIEM solutions because almost everything can be integrated."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"The initial setup was straightforward. I didn't have any problems."
"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."
"AlienVault OSSIM's GUI is very user-friendly."
More AlienVault OSSIM pros
"IBM Watson for Cyber Security is very stable."
"The most valuable features of IBM Watson for Cyber Security are ease of use and out-of-the-box reports and compliance policies. Additionally, if there are aspects that are missing IBM add them in the next release."
"The customer support is very good."
"The most valuable feature of this product is innovation, where the research and upgrading of technology never ends."
 

Cons

"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."
"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."
"The price of this solution is very high and it could be cheaper."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"The user interface could be improved."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Lacking in depth of reporting."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
More AlienVault OSSIM cons
"This is an expensive product, so making it more cost-effective would be an improvement."
"In the future, I would like to see threat intelligence included."
"They need to continue to build the AI capabilities."
"The dashboard could improve in IBM Watson for Cyber Security."
 

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."
"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."
"We are using the community version, which can be used for free."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is expensive compared to its competitors."
"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 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 licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
More AlienVault OSSIM pricing and cost advice
"IBM Watson for Cyber Security is very simple to license and is priced well."
"The price of this solution should be lower, although I understand why IBM charges a premium price."

Overview

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.

AT&T
Watson for cyber security can draw security intelligence from millions of security blogs, online forums and white papers - so you can see threats unseen by other systems.
