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.

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

"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"I have deployed it widely because I find that it gives value for money."
"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."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"AlienVault OSSIM's GUI is very user-friendly."
"The initial setup was straightforward. I didn't have any problems."
"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."
"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."
"Exabeam is very easy to use, with a straightforward platform and workflow, unlike other tools that require more expertise."
"Exabeam includes machine learning features and out-of-the-box rules that we rely on."
"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."
"I have seen a return on investment with Exabeam Fusion SIEM, and it is worth the money."
"The solution's initial setup process is easy."
"Overall, this is a fantastic tool and it is one of the best SIEMs that I've come across."
"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."
 

Cons

"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"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."
"Sometimes it takes very long for your issue to get resolved."
"We need more dashboards and we need more customization for dashboards."
"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."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"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."
"The product is good but the organization is rigid and not flexible in the way they operate."
"Updating the new release of Exabeam Fusion SIEM takes time and slows our performance."
"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 documentation and provide more customization for dashboards and case management."
"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."
"I would say the pricing for Exabeam Fusion SIEM is not cost prohibitive, but it was a little more than I initially thought."
"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."
 

Pricing and Cost Advice

"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."
"The solution is open source, so it's free to use."
"OSSIM is free."
"OSSIM is open source, and USM is the paid license. So, if you want, you can switch to USM. There you will have to buy a license, and they have a support team that helps you out on issues you face."
"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."
"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 tool's licensing costs are yearly."
"We are using the community version, which can be used for free."
"There is an annual license required to use Exabeam Fusion SIEM. The price of the solution should be reduced."
"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."
"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."
"Exabeam is not a cheap solution."
