An easy-to-scale open-source solution used for monitoring events on devices

The area for improvement is a lot. When I started using it on our enterprise side, the issue we faced was, for example, if we were running at that time on AlienVault OSSIM v5.7.4. So, for some orders, we had to install some packages, and when we tried installing that package, some dependencies got upgraded to a new version. Now once that dependency got upgraded, the SQL, since you might be aware that OSSIM uses SQL database, now SQL and all the dependency in everything was not on the same version, and that caused the database to crash. The aforementioned area should be eased out by upgrading the patches and upgrading dependencies. This kind of thing is a disadvantage of OSSIM, and I would like them to work on this. But I have also raised service requests many times and gave it a push on the community section too. However, since it is a local source, they don't reply much over there. That is why I don't like to work on OSSIM because it is unpredictable. Once the storage goes above 50 percent, it starts behaving unpredictably. If you get stuck with a situation, then you need to drill a lockdown into that. Sometimes you get no luck. Then you have to just reimage the server with the new fresh OS of AlienVault. As for additional features, not much because if you move to the newer version, it is kind of getting more stable. But, to make my life easier, then I would say try to give more features. I know it's open source, so they also cannot provide me with more features. But still, if they can provide me with more features because right now it's becoming old. Right now, we are even moving from SIEM to Security Data Lake. So when we move to it, this will be literally outdated. No one can even expect anything out of it. The way security is moving, it will be outdated very soon. They have to also provide something new to keep this going for the future also.

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

"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."

"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. They are very persistent in terms of keeping up with security protocols."

"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."

"Asset discovery is good."

"Network traffic analysis is highly efficient."

"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."

"The product is majorly used for threat detection of the agents on servers and endpoints."

More AlienVault OSSIM pros

"Wazuh's most valuable features include file monitoring and compliance reporting, which do not require excessive costs."

"The configuration assessment and Pile integrity monitoring features are decent."

"Overall, I rate Wazuh a nine out of ten."

"Wazuh's most beneficial features for our security needs are flexibility, built-in rules, integration capabilities, and documentation."

"The product’s interface is intuitive."

"I like the features we use, including malware detection, inventory, detection of hidden processes, and activity logs. Inventory is probably the most important feature. It tells us when processes and packages were installed and what they are, which is helpful."

"The most valuable feature of Wazuh is the ELK for doing an investigation."

"I find the PCI DSS feature the most valuable, along with the feature that monitors the compliance of Windows and the CIS benchmarks on other devices like Unix or Linux systems."

More Wazuh pros

Cons

"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."

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

"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."

"Sometimes technical issues take very long to get resolved."

"The incidence reporting could be better."

"I don't like to work on OSSIM because it is unpredictable."

"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."

"GUI could be improved."

More AlienVault OSSIM cons

"I want more support for regional compliance standards to serve my ANZ region customers better."

"They could include flexibility and customization capabilities by modifying for customers based on partner agreements."

"There could be a hardware monitoring tool for the solution."

"While it is scalable, it can suffer from reduced latencies."

"The support team could be more responsive and provide quicker replies during our working hours in Indonesia, which would be a significant improvement."

"Wazuh has a drawback with regard to Unix systems. The solution does not allow us to do real-time monitoring for Unix systems. If usage increases, it would be a heavy fall on the other SIEM solutions or event monitoring solutions."

"The deployment is a bit complex."

"It would be great if there could be customization for the decoder portion."

More Wazuh cons

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."

"OSSIM is 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 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."

"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."

"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."

"AlienVault OSSIM is an open-source solution."

"The tool's licensing costs are yearly."

Overview

AlienVault OSSIM, Open Source Security Information and Event Management (SIEM), provides you with a feature-rich open source SIEM complete with event collection, normalization and correlation. Launched by security engineers because of the lack of available open source products, AlienVault OSSIM was created specifically to address the reality many security professionals face: A SIEM, whether it is open source or commercial, is virtually useless without the basic security controls necessary for security visibility.

AT&T

Wazuh is an enterprise-ready platform used for security monitoring. It is a free and open-source platform that is used for threat detection, incident response and compliance, and integrity monitoring. Wazuh is capable of protecting workloads across virtualized, on-premises, containerized, and cloud-based environments.

It consists of an endpoint security agent and a management server. Additionally, Wazuh is fully integrated with the Elastic Stack, allowing users the ability to navigate through security alerts via a data visualization tool.

Wazuh’s agent can run on many different platforms, and is lightweight. It can successfully perform the tasks needed to detect threats in order to trigger responses automatically.
Wazuh manages the agents, can analyze agent data, and can scale horizontally.
Elastic Stack is where alerts are indexed and stored.

Wazuh Capabilities

Some of Wazuh’s most notable capabilities include:

Intrusion detection: Wazuh’s agents can detect hidden files, cloaked processes, or unregistered network listeners, as well as inconsistencies in system call responses. Wazuh’s server component uses a signature-based approach to intrusion detection, using its regular expression engine to analyze collected log data and look for indicators of compromise.
Log data analysis: Wazuh can read operating system and application logs, and securely forward them to a central manager for rule-based analysis and storage.
Integrity monitoring: File integrity monitoring can help identify changes in content, ownership, permissions, and attribute of files. Wazuh’s file integrity monitoring can be used in conjunction with threat intelligence.
Vulnerability detection: Wazuh agents can identify well-known vulnerable software so you can see where your weak spots are and take action before an attack can exploit them.
Configuration assessment: System and application configurations are monitored to make sure they are compliant with security policies. Periodic scans are used to detect applications that are known to be vulnerable, insecurely configured, or unpatched.
Incident response: Wazuh responds actively when active threats need to be addressed. It can perform countermeasures like blocking access to a system when a threat source is identified.
Regulatory compliance: Wazuh includes the security controls required to be compliant with industry regulations and standards.
Cloud security: Wazuh’s light-weight and multi-platform agents are commonly used to monitor cloud environments at the instance level. In addition, Wazuh helps monitor cloud infrastructure at an API level.
Security for containers: With Wazuh, you have increased security visibility into hosts and containers, allowing for easier detection of threats, anomalies, and vulnerabilities.
