Featured Reviews

HarshBhardiya - PeerSpot reviewer
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.

Evaluating robust file monitoring with insights for community support improvements
Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs. These aspects are vital as they provide alerts for changes and facilitate the monitoring of compliance. The platform is also relatively easy to set up and operate. Reports are straightforward to extract and prove useful for compliance requirements.

Quotes from Members

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

Pros

"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"Asset discovery is good."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"Better than other SIEM solutions because almost everything can be integrated."
"The product is easy to use."
"You can customize the dashboards as well as the reporting."
"The threat policies of the solution are always very advanced and the best in the market. They are very persistent in terms of keeping up with security protocols."
"It is a stable solution."
"Wazuh is free and easy to use. It is also adjustable, and we can use it on the cloud and on-premises."
"Wazuh has very flexible and robust features."
"I like the cloud-native infrastructure and that it's free. We didn't have to pay anything, and it has the capabilities of many premium solutions in the market. We could integrate all of our services and infrastructure in the cloud with Wazuh. From an integration point of view, Wazuh is pretty good. I had a good experience with this platform."
"The product's initial setup phase was easy."
"The solution is easy to maintain."
"It offers built-in modules for file integrity and vulnerability management."
"Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs."
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."
"Lacking in depth of reporting."
"The correlation engine needs to be improved."
"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 documentation could be improved."
"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"So far, the recent updates have addressed most challenges we previously faced."
"Its configuration process is time-consuming."
"Scalability is a constraint in the on-prem version of Wazuh in terms of the volume of logs we can manage."
"We would like to see more improvements on the cloud."
"Adding the flexibility to integrate various plug-ins or modules into its core system would enhance functionality."
"While it is scalable, it can suffer from reduced latencies."
"Scalability is a challenge because it is distributed architecture and it uses Elastic DB. Their Elastic DB doesn't allow open source waste application."
"The support team could be more responsive and provide quicker replies during our working hours in Indonesia, which would be a significant improvement."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The tool's licensing costs are yearly."
"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."
"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 price of AlienVault OSSIM is too high sometimes for us to present to our customers. The price should be lower. We are on a three-year license to use the solution. We had to pay extra for the support."
"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."
"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."
"We use the free version of Wazuh."
"The product price is neither too high nor too low."
"Wazuh is free and open source."
"There is not a license required for Wazuh."
"Wazuh has a community edition, and I was using that. It's free and open source."
"The product is cheaper compared to other tools."
"Wazuh is an open-source tool."
