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.

Chief Product Officer at ClusterPower

Has improved threat detection with deep log analysis and streamlined investigation workflows

The most useful features I find in Elastic Security are the forensic ones that allow us to carry deeper analysis into the logs for in-depth investigations, and the dashboards, with the reporting dashboard being quite user-friendly. Elastic Security is quite good at identifying threats, as it is part of the deep investigation tool that I mentioned before. Unless we need to look further into a certain log, we can carry out a deeper analysis and forensics on those particular logs. I can assess the impact of Elastic Security's real-time data analysis on our threat response efficiency as working pretty good. We are looking for real-time analysis because we have a continuous inflow of logs from different sources: from our cloud, from Active Directory, from our network. So it works pretty well.

Quotes from Members

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

Pros

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

"AlienVault OSSIM's GUI is very user-friendly."

"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."

"Asset discovery is good."

"Network traffic analysis is highly efficient."

"The product is easy to use."

"Its user-friendliness is the most valuable. It is very easy to use and explore. The dashboard is very well packaged and integrated. You don't have to spend a lot of time in configuring it and checking out the RPM etc. It is also free and very powerful."

"The solution is free to use."

More AlienVault OSSIM pros

"Elastic has a lot of beats, such as Winlogbeat and Filebeat. Beats are the agents that have to be installed on the terminals to send the data. When we install beats or Elastic agents on every terminal, they don't overload the terminals. In other SIEM solutions such as Splunk or QRadar, when beats or agents are installed on endpoints, they are very heavy for the terminals. They consume a lot of power of the terminals, whereas Elastic agents hardly consume any power and don't overload the terminals."

"Enables monitoring of application performance and the ability to predict behaviors."

"The solution has a good community surrounding it for lots of helpful documentation for troubleshooting purposes."

"The most valuable feature for me is Discover."

"It's very stable and reliable."

"Elastic Security helps improve the security posture of Pakistan through centralized visibility and real-time processing."

"Elastic Security is cost-effective compared to Defender and CrowdStrike."

"The most valuable feature is the search function, which allows me to go directly to the target to see the specific line a customer is searching for."

More Elastic Security pros

Cons

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

"Lacking in depth of reporting."

"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."

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

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"The correlation engine needs to be improved."

"GUI could be improved."

"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."

More AlienVault OSSIM cons

"The setup process is complex. You need a solid working knowledge of networking, operating systems, and a little programming."

"Improvements in Elastic Security could include refining and normalizing queries to make them more user-friendly, enhancing the user experience with better documentation, and addressing any latency issues."

"The solution should generate an automatic product that integrates with ELK Stack to use artificial intelligence."

"Elastic Security's maintenance is hard and its scalability is a challenge. There are complications in scaling and upgrading. The solution needs to also provide periodic upgrade checks."

"The problem with ELK is it's difficult to administer. When you have a problem, it can be very, very difficult to rebuild indexes."

"The training that is offered for Elastic is in need of improvement because there is no depth to it."

"The solution's query building is not that intuitive compared to other solutions."

"Their visuals and graphs need to be better."

More Elastic Security cons

Pricing and Cost Advice

"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."

"AlienVault OSSIM is expensive compared to its competitors."

"AlienVault OSSIM is free."

"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 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 tool's licensing costs are yearly."

"OSSIM is free."

More AlienVault OSSIM pricing and cost advice

"Compared to other tools, Elastic Security is a cheaper solution."

"The solution is not expensive and costs around ten dollars a month."

"There is no charge for using the open-source version."

"When compared to other products, the price is average or on the low side."

"Elastic Stack is an open-source tool. You don't have to pay anything for the components."

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.
