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.

Enterprise Account Manager South at a outsourcing company with 201-500 employees

Advanced analytics have transformed our threat detection and streamlined incident investigations

I would appreciate seeing additional dashboards in Exabeam Fusion SIEM or perhaps more options or the ability to customize them further. While we can customize them currently, there may be additional options available. I value the outcomes navigator because it matches the log piece to the use cases, which is helpful. The correlation rules are excellent. I am interested in whether there are additional threat intelligence feeds available that we could use, whether we can integrate our own, or if we could ingest different ones.

Quotes from Members

"Technical support is excellent; they are very helpful and responsive."

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

"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 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," and the solution works well and allows me to have visibility into anomalous events."

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"Better than other SIEM solutions because almost everything can be integrated."

More AlienVault OSSIM pros

"Overall, this is a fantastic tool and it is one of the best SIEMs that I've come across."

"The user interface and the timelines they use are the most valuable features, and 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 is the timeline creation based on log sources, which helps in security investigations."

"The Exabeam SIEM has a user friendly UI interface."

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

"I have seen a return on investment with Exabeam Fusion SIEM, and it is worth the money."

"The way it can connect with AWS is very useful, and the integrations are pretty good."

More Exabeam pros

Cons

"ArcSight works better than AlienVault right now."

"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."

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

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

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

"The correlation engine needs to be improved."

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."

More AlienVault OSSIM cons

"We use the on-prem Exabeam product and face limitations using the web UI and administration of custom models and rules."

"Exabeam needs to improve its adaptive nature towards rules and its capability to understand the entire client environment faster."

"Exabeam needs to improve its documentation and provide more customization for dashboards and case management."

"One area for the solution's improvement is integration capabilities, particularly out-of-the-box integration which sometimes requires additional professional services."

"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."

"I would say the pricing for Exabeam Fusion SIEM is not cost prohibitive, but it was a little more than I initially thought."

"The customer service and support are not satisfactory."

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

More Exabeam cons

Pricing and Cost Advice

"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."

"AlienVault OSSIM is free."

"OSSIM is free."

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

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

"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."

More AlienVault OSSIM pricing and cost advice

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

"Exabeam Fusion SIEM's pricing is reasonable."

"Exabeam is not a cheap solution."

"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."

"The solution is expensive."
