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

"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"Network traffic analysis is highly efficient."
"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.""
"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 product is majorly used for threat detection of the agents on servers and endpoints."
"The open vault component and the checking of vulnerabilities are the most valuable features. The page management helps with this. If you know how your device is vulnerable at least you can do something about it."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"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."
"It protect us from multiple authentication values, unauthorized access and antivirus threats."
"The most valuable feature of the solution is its ability to rectify a situation involving any anomalies expeditiously."
"It has the ability to summarize all the other security products and give us a one-stop-shop dashboard."
"There are many things I appreciate about IBM Security QRadar; I haven't used any other SIEM before IBM Security QRadar, so for me, it is perfect."
"The most valuable feature is user behavior analytics (UBA)."
"We have worked with other solutions, such as LogRhythm and Splunk. Compared to others, IBM QRadar has the best price-performance ratio so that you are able to reserve minimum costs. It starts settling in fast and gets the first results very quickly. It is also very scalable."
"I am fond of IBM Security QRadar because it is very user-friendly."
 

Cons

"I don't like to work on OSSIM because it is unpredictable."
"The incidence reporting could be better."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"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."
"AlienVault OSSIM gives unwanted notifications."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"Sometimes technical issues take very long to get resolved."
"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."
"I would like to see the update process simplified."
"Pricing model could be more cost-effective."
"I would also like to see more integration with other vendors. IBM doesn't integrate well with products from China, like Huawei. Many Middle Eastern customers are switching to Huawei from American vendors like Cisco because of the price. In most RFPs, Huawei wins because it costs less."
"The technical support is poor. Mostly because when I open a PMR for IBM, I am stuck with Level 1 staff."
"The dashboards and reports may need to improve."
"The released patch quality is poor. IBM should test those patches on their side, not on the client's side."
"I would like to see some artificial intelligence and alternative solutions."
"IBM technical support is always terrible."
 

Pricing and Cost Advice

"We are using the community version, which can be used for free."
"AlienVault OSSIM is an open-source solution."
"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 expensive compared to its competitors."
"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."
"The solution is open source, so it's free to use."
"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."
"We pay approximately $40,000 to use the solution annually. This solution is a lot less expensive than Splunk."
"You have a one-time payment, and you also can purchase it for one year as a subscription. We have it on-premise, and we have a permanent license for it. We have to pay for the support on a yearly basis. If you compare its cost with Sentinel for one year, QRadar would seem more expensive, but if you compare its cost over five or ten years, Azure Sentinel will be more expensive than QRadar. If you compare its cost with Sentinel for one year, QRadar would seem more expensive, but if you compare its cost over five or 10 years, Azure Sentinel can be more expensive than QRadar."
"There are additional costs, such as the cost associated with the different hardware required for implementation and deployment. Along with the add-on apps, these are all additional costs, and they require licensing as well."
"The price of this product is high."
"This price is a little high, so it's an expensive product."
"The product is expensive. We have purchased the perpetual license, but we pay for the support."
"It is a perpetual license that we have for the event collector. The licensing is done based on the number of events and flows that you receive on this particular device. These are perpetual licenses, which means once you purchase them, they don't expire, which means that the support to IBM is definitely renewed after every one year. We have an enterprise agreement with IBM, which puts the cost in a totally different category as compared to someone who is not an IBM partner and is approaching IBM for this solution. We were able to get massive discounts. To give you an idea, we recently purchased 30,000 event licenses, and it costs around $480,000. It is definitely not a cheap product. We have licenses for about 270,000 events per second and 3 million flows per second. All the appliances and their events and flows are basically clubbed together and charged or rather calculated through a single source. The console receives all the details from all the event processes that we have globally. So, the license that we have is a single license for 270,000 events per second and 3 million flows per second, but that can be managed centrally. I was only part of the secondary purchase, which was 30,000 events per second for about $480,000. You can calculate how much we paid for 270,000 events. Reducing its price would be a compromise. We have already used a lower-priced product in the form of NNT, but we had to get rid of it because it was not doing the job that we actually wanted to do. You get what you pay for."
"Most of the time, it is easier and cheaper to buy a new product or the QRadar box."
