An open-source solution that provide good detection and more visibility

The solution is not scalable. It impacts so hard. In the initial stages, AlienVault OSSIM can be suitable for small environments. There may be limitations if the customer expresses a desire to expand and add more devices. In such cases, we would need to either explore additional solutions or work within the constraints of the existing setup. We have set up alerts and configured everything in AlienVault OSSIM. It actively monitors for any security incidents. It provides us with regular updates and notifications about any ongoing activities. Only one person is using the solution. It is the perfect solution for small businesses. I rate the solution’s scalability a three out of ten.

The SIEM provides a user-friendly UI experience

When events come into the system, the dashboard categorizes them by the highest risk score, not when they appear on the system. When you've got multiple ongoing incidents you can only see the highest risk score at the top of the list rather than the most recent detection. Exabeam's reporting dashboard could have included a filtering option to filter by the most recent detection.

Quotes from Members

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

Pros

"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."

"I recommend it due to the experience of the people running it."

"The paid version of the solution has reporting and better scalability options."

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

"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."

"The solution is very stable. Compared to Qradar and Splunk, it's very stable."

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

"The initial setup is straightforward."

More AlienVault OSSIM pros

"Exabeam includes machine learning features and out-of-the-box rules that we rely on."

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

"It's a very user-friendly product and it's a very comprehensive technology."

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

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

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

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

"The UI was very clean."

More Exabeam pros

Cons

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

"They can add more compliance templates."

"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."

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

"The solution is not scalable."

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

"The documentation could be improved."

"The incidence reporting could be better."

More AlienVault OSSIM cons

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

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

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

"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."

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

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

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

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."

"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."

"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."

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

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

"OSSIM is free."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"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."

"Exabeam is not a cheap solution."

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

"Exabeam Fusion SIEM's pricing is reasonable."
