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.

Optimizing time and effort through comprehensive auditing features

Netwrix Auditor doesn't have many competitors at the level in which it is placed. All other companies provide auditing solutions but not up to the feature list; it is very broad and robust. The best features include flexibility to interact directly with MS-SQL. Real-time alerts help identify potential security threats. The ability to streamline audits with insights into configuration states is helpful, as the access reviews and audit reports are really insightful. This is a good tool. The search functionality is available, but comparative to other vendors, this is a bit slower. Reports are effective; the compliance reports and all the reports are very insightful. That is good.

Quotes from Members

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

Pros

"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."

"Network traffic analysis is highly efficient."

"The initial setup was straightforward. I didn't have any problems."

"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."

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

"Asset discovery is good."

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

"The most valuable features of this solution are the data correlation and vulnerability assessment."

More AlienVault OSSIM pros

"It maintains audit logs for the duration of time that you wish, as long as you have the storage capacity to do so."

"The most valuable feature is the real-time monitoring."

"I am impressed with the tool's reporting feature and notifications."

"Netwrix Auditor doesn't have many competitors at the level in which it is placed; all other companies provide auditing solutions but not up to the feature list—it is very broad and robust."

"I have found user behavior analysis and the ability to run risk assessments important features. Additionally, the interface and online documentation are very good."

"Netwrix provides features that no other solution on the market does."

"What I find the most valuable about Netwrix Auditor is the way it shows risk. The reports are very clear."

"The most valuable features of Netwrix Auditor are its affordability compared to similar products and its comprehensive monitoring of admin activities."

Cons

"The user interface could be improved."

"AlienVault OSSIM should improve the deployment and make it unified like the USM."

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

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

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

"AlienVault OSSIM gives unwanted notifications."

"The user interface needs to be friendlier across the board."

"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."

More AlienVault OSSIM cons

"When there are issues I would like remediation to be in one place."

"In the UI, we have to adjust and resize our console many times, and sometimes it appears, sometimes you have to close and open it, and sometimes it does not give a scroll bar to navigate."

"There is room for improvements when it comes to the licensing."

"There is room for improvement with the introduction of AI functionality."

"The solution lacks self-service on password reset. It also needs to improve its scalability."

"I expect usability features to become more refined over time. I'm interested to see how it evolves and continues to improve."

"If you buy direct, there is a minimum of 150 licenses that must be procured. The price point and barrier of entry is a little bit higher than it would be if you purchased the solution from an authorized reseller partner, rather than buying it and managing yourself."

"The Linux compatibility of this solution could be improved."

More Netwrix Auditor cons

Pricing and Cost Advice

"AlienVault OSSIM is free."

"AlienVault OSSIM is an open-source solution."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

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

"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 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."

More AlienVault OSSIM pricing and cost advice
