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

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

Pros

"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."

"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 initial setup was straightforward. I didn't have any problems."

"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."

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

"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."

"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."

"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."

More AlienVault OSSIM pros

"The solution has great technology, it's a very user-friendly product and a very comprehensive technology, the security on offer is very good, and cost-wise, compared to other technology, it's affordable."

"I have customers that like the EUBA functionality of it; the solution has the ability to build a session, basically, pulling a lot of information together, for example, everything a user does in a specific timeframe, which is quite helpful."

"The advanced analytics has a really great overview of user behavior."

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

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

"Exabeam is very easy to use, with a straightforward platform and workflow, unlike other tools that require more expertise."

"We evaluated LogRhythm and Splunk as possible options but in the end, we went with Exabeam - it was the right choice for us taking into account the needs of our customers and projected future needs."

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

More Exabeam pros

Cons

"We need more dashboards and we need more customization for dashboards."

"Sometimes it takes very long for your issue to get resolved."

"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 main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."

"GUI could be improved."

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

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

"The documentation could be improved."

More AlienVault OSSIM cons

"The product is good but the organization is rigid and not flexible in the way they operate."

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

"I believe if it were more flexible it would be a better product."

"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."

"Exabeam's integration capabilities are not good, as Exabeam has a very limited number of integrations and no out-of-box integration, which is an area where Exabeam should improve."

"The solution's reporting and dashboarding could be improved."

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

More Exabeam cons

Pricing and Cost Advice

"OSSIM is free."

"AlienVault OSSIM is free."

"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."

"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."

"AlienVault OSSIM is expensive compared to its competitors."

"AlienVault OSSIM is an open-source solution."

"The tool's licensing costs are yearly."

More AlienVault OSSIM pricing and cost advice

"Exabeam Fusion SIEM's pricing is reasonable."

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

"The solution is expensive."

"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."
