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.

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."

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

"With AlienVault you get everything in one box."

"AlienVault OSSIM's GUI is very user-friendly."

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

"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."

"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."

More AlienVault OSSIM pros

"Exabeam Fusion SIEM has a good performance and more advantages than traditional solutions."

"The most valuable feature of Exabeam is the timeline creation based on log sources, which helps in security investigations."

"The ThreatHunter in Advanced Analytics is the most valuable. It helps analyze compromised assets and provides analysis for any entity within my client's environment."

"It is user-friendly and quite simple to use."

"The solution's initial setup process is easy."

"The user interface and the timelines they use are the most valuable features. The price model is very simple so that one can understand it easily and there are no surprises within it."

"The most valuable feature of Exabeam Fusion SIEM is the easy-to-use user interface."

"Exabeam has improved our organization by speeding up the investigation process."

More Exabeam pros

Cons

"The correlation engine needs to be improved."

"The price of this solution is very high and it could be cheaper."

"They can add more compliance templates."

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"Lacking in depth of reporting."

More AlienVault OSSIM cons

"The organzation is rigid and not flexible in the way they operate"

"They need to focus on more of the MITRE ATT&CK Framework and coverage. They claim they cover about 70 to 80%. I'm not sure if it's really quite that much, however."

"They should provide detailed information about detecting phishing emails."

"We had a large volume right from the beginning and they weren't quite prepared for that. That's something that they should think about when it comes to customers that have a large volume to start off with."

"The initial setup of Exabeam Fusion SIEM is complex because it needs to integrate with the SIEM solution, but after this is complete it is straightforward."

"Exabeam lacks customizable dashboards, which might be a limitation if visualization is a key requirement."

"Updating the new release of Exabeam Fusion SIEM takes time and slows our performance."

"We still have questions surrounding hardware deployment."

More Exabeam cons

Pricing and Cost Advice

"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."

"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."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"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 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."

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

More AlienVault OSSIM pricing and cost advice

"Exabeam Fusion SIEM's pricing is reasonable."

"Exabeam is not a cheap solution."

"The solution is expensive."

"The platform is not extremely expensive compared to its direct competitors; I would rate its pricing around six out of ten."

"They have a great model for pricing that can be based either on user count or gigabits per day."

"There is an annual license required to use Exabeam Fusion SIEM. The price of the solution should be reduced."
