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 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 solution is free to use."
"The paid version of the solution has reporting and better scalability options."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"The threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"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.""
"It does good correlation for events. It does good general analysis, and it has good apps as well."
"Paradigm shift, security intelligence 2.0 Contextual-based incident management Threat-based incident management A single management console to handle all the data Ease of use Existing integration capabilities Out-of-the-box reports Parser development"
"There are new things that are coming up in QRadar, such as AI to IBM Watson, which is going to create a huge impact in these types of solutions."
"I like the graphical interface. It's so good and easy."
"We have much better visibility into our environment now."
"The user behavior analytics as part of our deployment was okay, even though it was clunky."
"IBM QRadar is great help from its security event monitoring to data center and NOC troubleshooting of issues hard for other departments to spot."
"I have found the most important features to be the flexibility, tech framework, and disk manager."
 

Cons

"The user interface needs to be friendlier across the board."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"It does not give me a prompt response for any such malicious traffic; it takes time to get that alert from the AlienVault system."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The solution needs more integration with cyber intelligence systems."
"AlienVault OSSIM is costly."
"They can add more compliance templates."
"The quality of technical support depends on the IBM support person. Sometimes, it's hard to get the right person on the other side. A ticket coordinator could be the key to better quality delivery."
"Some of the cloud apps need improvement."
"QRadar log integration of various applications can be a tough job at times."
"We experienced some memory usage issues with a user behavior app."
"There are many limitations in using SAP, EBS, or Micro-Dynamics; a lot of things that are happening in those platforms could also be monitored and allowed from the cybersecurity risks perspective."
"The concern with QRadar is that there are so many features in the dashboard, too many menus that require going to two or three sub-monitors to enter the QRadar."
"There is a shortage of skilled individuals with knowledge about the solution. There is training required."
"It's resource-intensive."
 

Pricing and Cost Advice

"AlienVault OSSIM is free."
"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."
"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."
"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."
"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 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."
"They can give us some scalability and flexibility on pricing. If its pricing can be reduced, it would help a lot of customers in bringing in a new SIEM environment and grow business in the market. If I start a license today and take around 10,000 EPS, and after a month, there is an increase in the number of clients on my platform, I can increase the number of licenses. I can add 5,000 EPS on a yearly basis."
"There is a license required for this solution."
"QRadar is quite expensive. It wouldn't be worth it for a small business..."
"The solution is costly and the price differs depending on the vendor you use."
"There is an annual license required for this solution."
"I think that the price is fair, but we can always say that the price could be cheaper."
"Pricing is good."
"Our licensing costs for this solution is on a yearly basis."
