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.

Have managed daily asset and alert monitoring effectively but have encountered limitations with manual processes and interface usability
It's still very manual and doesn't work on its own. It's still in an early stage and not on par where we can consider it a really successful detection system. The accuracy is not there. The UI could be better when compared to Sentinels where we can use flags and tagging. It could be much more user-friendly. IBM Security QRadar has all features and is fully competitive with other SIEM tools, but when it comes to user-friendliness, a new user takes time to get used to it. More intuitive, user-friendly interfaces and more helpful documentation would be beneficial. The query searching and data fetching could be faster. In large to very large organizations with around 5,000 or 6,000 assets or beyond, even with proper configurations and RAM and hardware backing up, the query is fairly slow.

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."
"Better than other SIEM solutions because almost everything can be integrated."
"You pay monthly for the solution. I think it's one of the best products. If you compare with other companies, like LogRhythm, etc., the top 8 or 10 CMs, I think Alien Vault has the best price-performance ratio."
"The most valuable features of this solution are the data correlation and vulnerability assessment."
"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 open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"I recommend it due to the experience of the people running it."
"The solution is free to use."
"The feature that I have found most valuable is its artificial intelligence component, Watson. Its contribution is pretty good from a machine-learning artificial intelligence perspective. This compliments the orchestration automation component, as well."
"I find that the dashboards are the most helpful to get an overview of traffic flow and issues."
"It can analyze event logs, event security, and give a good consult."
"The technical support is very good."
"For small and medium enterprises, QRadar is the best solution, due to its price and performance."
"Troubleshooting more complex issues became much simpler with the addition of this product."
"It captures and processes large volumes of event data, and scales to support hundreds of thousands of events in one unified database."
"With QRadar, you can do all these, even if you are not a security expert."
 

Cons

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."
"The incidence reporting could be better."
"Sometimes it takes very long for your issue to get resolved."
"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 initial setup was not so easy, partly because the documentation was not up to date."
"They can add more compliance templates."
"The user interface could be improved."
"When comparing AlienVault OSSIM to other solutions it looks a bit outdated. Additionally, they need to improve their integration."
"IBM QRadar is pricey, and therefore, usually small enterprises are not able to afford it."
"I have noticed the interface has room for improvement."
"I would suggest QRadar release any documentation or give an online demo, like videos on YouTube. It would increase publicity and public appeal."
"The product can be a bit complex."
"I gave IBM Security QRadar a score of six or seven out of ten because it has a very basic interface; the dashboards require extension management for better usability."
"In terms of where it could be improved, this includes its forensics, incident response, and security operation center features."
"I'd like to see it being able to be integrated with more security products."
"GUI needs to be improved."
 

Pricing and Cost Advice

"AlienVault OSSIM is an open-source solution."
"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."
"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."
"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."
"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."
"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 OSSIM is free."
"The solution is open source, so it's free to use."
"The solution is costly and the price differs depending on the vendor you use."
"It is overly expensive and overly complex in terms of licensing. They have many different appliances, which makes it extremely difficult to choose the technology. It is very difficult to choose the technology or QRadar components that you should be deploying. They have improved some of it in the last few years. They have made it slightly easy with the fact that you can now buy virtual versions of all the appliances, which is good, but it is still very fragmented. For instance, on some of the smaller appliances, there is no upgrade path. So, if you exceed the capacity of the appliance, you have to buy a bigger appliance, which is not helpful because it is quite a major cost. If you want to add more disks to the system, they'll say that you can't."
"The tool is priced in a competitive manner. The tool's price is dependent on the installation and the product size, but it is competitive in the marketplace."
"I think my company pays for the license yearly."
"QRadar's price is reasonable compared to LogRhythm."
"Only enterprise businesses can afford the tool."
"Pricing (based on EPS) will be more accurate."
"The price of this solution is reasonable."
