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.

A scalable SIEM solution for monitoring a user's activity in the file server

The most valuable features of the solution are its quick and simple features related to advanced permissions for files, allowing for what permission needs to be granted to the users when it comes to the monitoring folder in the solution. If someone who has been denied permission to use a particular folder tries to go to that folder, then the administrator gets a notification. In general, the administrator can easily gather and maintain records if a person who has been denied permission to a particular confidential folder tries to access it.

Quotes from Members

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

Pros

"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."

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

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."

"The dashboard is the solution's most valuable aspect. It brings everything into one central point where I can actually look at it and go, "Okay, I understand what's going on.""

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

"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."

"With AlienVault you get everything in one box."

More AlienVault OSSIM pros

"It is a good and stable solution...It is a scalable solution."

"Our customer acquires the complete report which is kept for future auditing purposes."

"Alerting upon file changes is the most valuable aspect of the product."

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"It's so hard to configure and explore something new on it."

"The incidence reporting could be better."

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."

"Lacking in depth of reporting."

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

"The documentation could be improved."

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

More AlienVault OSSIM cons

"The updates management and central management console could be improved."

"The DLP function, including installation of the agent on the workstation and controlling the DLP restrictions, are areas where the product lacks."

"Whenever someone cuts and paste, it shows as "file is deleted"."

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."

"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 free."

"AlienVault OSSIM is an open-source solution."

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

"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."

More AlienVault OSSIM pricing and cost advice

"FileAudit provides a trial license for 30 days, and after that, customers can choose between perpetual licensing or the annual-based licensing option offered by FileAudit."

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

Agentless, remote and non-intrusive, FileAudit offers a simple more user-friendly way to safeguard and secure file access in a Windows environment. FileAudit provides real-time monitoring and alerting on all access (or access attempts). FileAudit also implements contextual functions such as mass access and alteration alerts, tracking source IP address information for remote data access, and providing granular time and date alerting parameters to monitor folder and file access at unusual or unexpected times.
