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

"I recommend it due to the experience of the people running it."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"The initial setup is straightforward."
"The paid version of the solution has reporting and better scalability options."
"You can customize the dashboards as well as the reporting."
"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."
"Network traffic analysis is highly efficient."
"The product is easy to use."
"It protect us from multiple authentication values, unauthorized access and antivirus threats."
"Inside IBM QRadar there are a lot of engines that actually work to help us to do the correlation and normalization as well for the logs that we're receiving from multiple devices."
"It is a pretty solid product for the type that it is representing. It is a CM solution as compared to Splunk or ArcSight from HP. It is also user friendly. It comes with some internal AI as well, in which it automatically maps multiple lots from unrelated devices and makes a smart decision to link them back and create an offense based on that. It is a smart tool."
"IBM QRadar is easy to use."
"It showed us where weaknesses were in our environment, so we could actively target those patches first."
"What's most valuable in IBM QRadar User Behavior Analytics is its higher availability than other tools."
"The best feature of IBM QRadar is visualization which shows you when there's a spike in the system, and this makes you realize that there's something wrong with the log."
"The most valuable feature is that it reports a very small number of false positives."
 

Cons

"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"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."
"GUI could be improved."
"The documentation could be improved."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"The initial setup was not so easy, partly because the documentation was not up to date."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"Although QRadar provides incident management of the alerts it produces, this area could use a little improvement to allow more restrictions on who can close alerts and easily updating alerts with and reading text templates."
"We've used technical support and it hasn't been great."
"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."
"I'd like to see it being able to be integrated with more security products."
"Their technical support is not good. We opened a lot of cases and from my experience, they are not complicated issues but it takes forever to get an answer."
"Right now, if you look at the compatibility, if you need to deploy QRadar in a physical appliance you have only two choices of server, their own or a Lenovo server. In today's world, you cannot keep something tied to such a big brand. Clients want to be able to use whatever type of server they want."
"It should have built-in blocking capability."
"The technical support is poor. Mostly because when I open a PMR for IBM, I am stuck with Level 1 staff. As an engineer, nothing that I am bringing them does not require Level 2 or Level 3 support."
 

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."
"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."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"The tool's licensing costs are yearly."
"The maintenance costs are high."
"IBM has subscriptions plans that run for one year."
"There is a license required for this solution. There are some limitations depending on what license you purchase."
"The solution has a licensing model that is based on events per second so it scales to need and budget."
"The solution's pricing is based on the EPS model."
"It is expensive. It is not a product that I can provide for SMBs. It is a program that I can only provide for really large enterprises."
"There is a license to use this solution, which is paid annually. However, there are subscription options available."
"Licensing is very expensive, IBM QRadar is a very expensive solution. If you want to minimize costs then IBM QRadar is not for you."
