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.

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

"Network traffic analysis is highly efficient."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"Better than other SIEM solutions because almost everything can be integrated."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"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."
"What I like about this product, is that it is a fully-fledged solution."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"Timeline based analysis; good platform support"
"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."
"The advanced analytics has a really great overview of user behavior."
"Exabeam includes machine learning features and out-of-the-box rules that we rely on."
"Exabeam's UEBA displays the type of description that it could show in a console regarding one particular user, the rating that it shows, and how vulnerable the user is, which is very good."
"The solution's automation capabilities are great."
"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."
 

Cons

"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"Sometimes it takes very long for your issue to get resolved."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"The user interface could be improved."
"The initial setup was not so easy, partly because the documentation was not up to date."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM is costly."
"One area that needs improvement is interacting with Exabeam's API. There was a headache regarding the API; the documentation wasn't clear, and the syntax wasn't very precise."
"We use the on-prem Exabeam product and face limitations using the web UI and administration of custom models and rules."
"The customer service and support are not satisfactory."
"Exabeam should be a bit faster, especially in loading and vulnerability scanning."
"Exabeam needs to improve its adaptive nature towards rules and its capability to understand the entire client environment faster."
"I believe if it were more flexible it would be a better product."
"Adding to the number of certifications that they have, for example, ISO 27001, would be helpful. Currently, they only have SOC 2."
"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."
 

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."
"The solution is open source, so it's free to use."
"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."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault 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."
"They have a great model for pricing that can be based either on user count or gigabits per day."
"Exabeam Fusion SIEM's pricing is reasonable."
"There is an annual license required to use Exabeam Fusion SIEM. The price of the solution should be reduced."
"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."
