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.

SOC Engineer at a outsourcing company with 10,001+ employees
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

"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."
"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 solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The most valuable feature is the logging capability."
"The initial setup was straightforward. I didn't have any problems."
"With AlienVault you get everything in one box."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"The scalability is awesome, because QRadar includes other solutions in the same console."
"Most of our clients have seen a return on investment because compared to other solutions it does not require a busload of people to operate it and it is reasonably priced."
"IBM QRadar is phenomenal as a SIEM SOC solution."
"Flexible and valuable product that is modular, so you can easily set up a roadmap for your clients."
"The most valuable feature is that it reports a very small number of false positives."
"QRadar, Splunk, and ArcSight are SIEM solutions with built-in AI/ML features. They can do the complete investigation and alert the admin about what is happening. They can also do the root cause analysis. There are many other features that come with QRadar. It has a more granular log, so you can integrate with various non-IT as well as IT-based components. You can get unstructured data to the SIEM data, and you can identify more what is happening in the network or what is happening in the central head office. You can also identify what is happening between your remote offices. You can also use it to identify what the users in the field are doing on their devices and how things are moving. From the integration point of view, it is very centric. It gives complete control centrally. If a user is not connected to the system, whenever he comes online, we can see the policy updates over the Internet, and we can ensure that the data that is supposed to be protected is protected."
"IBM Security's QRadar Security Intelligence is a multi-feature security monitoring platform that provides log management, SIEM, NetFlow, application monitoring, vulnerability scanning, full packet capture and risk analysis."
"IBM QRadar is probably the best possible solution in the market."
 

Cons

"I would advise others to not implement it for any enterprise-level organization."
"They can add more compliance templates."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"The solution is not scalable."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"It is good, but when a product doesn't behave in a good manner, it creates confusion. Its behavior isn't consistent."
"I don't give it a 10 because it is something we have to request. I would love it if UBA was included out of the box like Microsoft."
"Trying to get answers out of IBM is like trying to get blood out of a stone. They need to be more helpful and responsive."
"GUI needs to be improved."
"The dashboards are all legacy and old."
"The architecture could be improved. I got stuck for a long time trying to understand the architecture, as it is quite challenging."
"IBM QRadar is pricey, and therefore, usually small enterprises are not able to afford it."
"From a functionality point of view, there are issues sometimes."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is free."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is an open-source solution."
"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."
"OSSIM is free."
"The solution is open source, so it's free to use."
"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."
"There is a license required for this solution."
"Its price is good in terms of efficiency and the number of people required for implementing various things. You might pay more in terms of money, but you might save on the number of people. For example, if you are using Kibana, you have to pay more for people or experts, which is not the case with IBM QRadar."
"Pricing and licensing are competitive. Their new licensing options allow logs to bypass the correlation engine for a flat rate, which is also appealing for log data that is compliance-driven for a small amount of money."
"QRadar's price is reasonable compared to LogRhythm."
"The solution is priced fairly, there is a license for the solution, and we pay annually."
"It's too expensive."
"There is a license to use this solution, which is paid annually. However, there are subscription options available."
"The solution comes with a high price tag, while some of the competitors provide identical functionality in their offerings at no extra cost."
