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 So when we move to it, this will be literally outdated.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 The way security is moving, it will be outdated very soon.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 can customize the dashboards as well as the reporting."

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

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."

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

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

"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."

"Asset discovery is good."

"The solution is free to use."

More AlienVault OSSIM pros

"Wazuh has very flexible and robust features."

"Regarding Wazuh, I find the SCA (Security Configuration Assessment) features most valuable. It's crucial for asset management and inventory, allowing us to monitorendpoints and servers' changes easily. This is particularly important for my customers, who aren't heavily focused on incident response but rely on asset management and inventories. Wazuh's compliance management features are very supportive, especially in regions like the Americas and Europe. However, it's less effective in the ANZ (Australia and New Zealand) region since Wazuh doesn't cater to the specific compliance standards there, such as those required in Australia. I appreciate that Wazuh fully complies with PCI DSS and GDPR standards, allowing us to generate necessary reports."

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

"The most valuable feature of Wazuh is its EDR capabilities."

"The product is easy to customize."

"The product's initial setup phase was easy."

"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."

"My company implemented Wazuh because it was relatively inexpensive. They could quickly get their hands on it to check a box for some audit and compliance."

More Wazuh pros

Cons

"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."

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

"Lacking in depth of reporting."

"The solution needs more integration with cyber intelligence systems."

"The documentation could be improved."

"AlienVault OSSIM’s configuration and integration could be a little easier."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"They can add more compliance templates."

More AlienVault OSSIM cons

"The product's configuration part and lack of AI capabilities are some of the major concerns associated with Wazuh."

"When I face a challenge, I prefer not to spend too much time on it and may move to another solution that will give us the results."

"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."

"Wazuh could improve the detection, it is not detecting all of the attacks. Additionally, it is lacking features compared to other solutions."

"One area where Wazuh could use some improvement is in its reporting mechanism, especially for high-level management like CSOs and CEOs."

"The technical support can be improved. Wazuh has some bugs that need to be fixed. It would be good if we can have automation with respect to incidence responses."

"Log data analysis could be improved. My IT team has been looking for an alternative because they want better log data for malware detection. We are also doing more container implementation also, so we need better container security, log data analysis, auditing and compliance, malware detection, etc."

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

More Wazuh cons

Pricing and Cost Advice

"The tool's licensing costs are yearly."

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

"AlienVault OSSIM is an open-source solution."

"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."

"OSSIM is free."

"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."

"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 OSSIM is expensive compared to its competitors."

More AlienVault OSSIM pricing and cost advice

"We use the free version of Wazuh."

"Wazuh is open-source, therefore it is free. You can purchase support for $1,000 a year."

"Wazuh has a community edition, and I was using that. It's free and open source."

"When I contacted customer care, they mentioned bundling options, that I found to be overall affordable."

"Wazuh is an open-source tool."

"Wazuh is a good tool, but the open-source version has scalability limitations."

"The solution's cost is above the average."

"The current pricing is open source."

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.

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.
