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

"The initial setup is straightforward."

"Asset discovery is good."

"The most valuable feature is the logging capability."

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

"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."

"Network traffic analysis is highly efficient."

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

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

More AlienVault OSSIM pros

"We like Elastic Security because it's a REST API-based solution. That's the primary reason we use it."

"The most valuable features of the solution are the prevention methods and the incident alerts."

"We chose the product based on the ability to scan for malware using a malware behavioral model as opposed to just a traditional hash-based antivirus. Therefore, it's not as intensive."

"It's very customizable, which is quite helpful."

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

"It's open-source and free to use."

"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."

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

More Elastic Security pros

Cons

"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."

"The documentation could be improved."

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

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

"AlienVault OSSIM is costly."

"The correlation engine needs to 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."

"The price of this solution is very high and it could be cheaper."

More AlienVault OSSIM cons

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

"The solution could also use better dashboards. They need to be more graphical, more matrix-like."

"I would like more ways to manage permissions and restrict access to certain users."

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

"Elastic Security consumes a lot of resources, requiring a substantial deployment setup."

"Elastic Security has a steep learning curve, so it takes some time to tune it and set it up for your environment. There are some costs associated with logging things that don't have value. So you need to be cautious to only log things that make sense and keep them around for as long as you need. You shouldn't hold onto things just because you think you might need them."

"I want to find an automatic security system in the tool, like a SOAR solution. I am looking forward to seeing a SOAR system in the tool."

"Installation is a little bit overwhelming, so improvements on the installation site could make it easier."

More Elastic Security cons

Pricing and Cost Advice

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

"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."

"AlienVault OSSIM is an open-source solution."

"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."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"The solution is free."

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

"It's a monthly cost with Elastic SIEM, but I am not sure of the exact cost."

"I find it better than Splunk in terms of cost-effectiveness. For cost-effectiveness, I would rate it a nine out of 10."

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

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

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

"Affordable but with additional costs"

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.
