BP
Independent Contractor at a comms service provider with 5,001-10,000 employees
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.

Has faced limitations in AI capabilities and pricing flexibility
Pricing-wise, Wazuh stands out, along with deployment flexibility and its documentation which is extremely good in comparison to Forti. The community support is also incredible. They have helped quite a bit because previously, we had a separate tool and management dashboard to do our compliance. With Wazuh, we receive that information without having to do anything extra. We just set up the SIEM and all of that information was automatically populated. The dashboards are very easy to understand and very quick with no lag or delay. I have experienced delays on Forti's dashboards, but not with Wazuh. Wazuh is quite good. In comparison to Forti, they are quite similar. They are very good at detection.

Quotes from Members

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

Pros

"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."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"Network traffic analysis is highly efficient."
"The paid version of the solution has reporting and better scalability options."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"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 product is easy to use."
"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."
"The product is easy to customize."
"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."
"I like that the solution is on top of the Kubernetes stack."
"Wazuh has very flexible and robust features."
"Wazuh offers numerous features, such as the ability to define custom rules for detecting malicious activities and remembering behaviors."
"It is a stable solution."
"Wazuh automatically scans the host for CIS benchmarks for the latest updates and vulnerabilities and gives a host score. It provides a percentage of perceived risk due to of non patches or any missing patches on that work."
 

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"Lacking in depth of reporting."
"The user interface could be improved."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"Sometimes it takes very long for your issue to get resolved."
"One area where Wazuh could use some improvement is in its reporting mechanism, especially for high-level management like CSOs and CEOs."
"There could be a hardware monitoring tool for the solution."
"The support channel is not optimal, and extensive research is required on our part to implement Wazuh effectively."
"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."
"I think that the next release should be more suitable for large enterprises, because currently they are not because large companies do not rely on open source solutions."
"The tool does not provide CTI to monitor darknet."
"The product's configuration part and lack of AI capabilities are some of the major concerns associated with Wazuh."
"The lack of AI features is an issue at the moment in the industry."
 

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."
"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 the community version, which can be used for free."
"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."
"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."
"The tool's licensing costs are yearly."
"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is free."
"It is a free-of-cost solution."
"They have a good pricing strategy for market expansion."
"Wazuh is an open-source tool, which means it is freely available for use."
"Wazuh has a community edition, and I was using that. It's free and open source."
"Wazuh is totally free and open source. There are no licensing costs, only support costs if you need them."
"Wazuh is a cheaply priced product."
"It is an open-source product."
"The solution's pricing is very competitive."
