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 have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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."
"Most of the SOC or SIEM enterprise class products are very expensive, whereas with OSSIM you can start out with a smaller setup and then expand as you wish."
"The most valuable feature is the logging capability."
"I recommend it due to the experience of the people running it."
"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," and the solution works well and allows me to have visibility into anomalous events."
"The initial setup was straightforward. I didn't have any problems."
"I think it has improved our organization by the speed at which I can run queries compared to other software that I've used in the past."
"Overall a great solution."
"It captures and processes large volumes of event data, and scales to support hundreds of thousands of events in one unified database."
"This console gives you the entire view, which makes life easier and allows you to take precautionary measures."
"I have found the most important features to be the flexibility, tech framework, and disk manager."
"This product helps to build a strong architecture, which is important to avoid problems."
"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"
"IBM QRadar User Behavior Analytics has easy architecture, has a good portfolio and integration."
 

Cons

"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"I suggest more in-built rules based on modern threats and environments to make it a more competitive solution."
"Sometimes it takes very long for your issue to get resolved."
"AlienVault OSSIM on-premise version is more difficult to implement than the cloud version. Additionally, they should add integration between several different environments at once and improve their online knowledge base."
"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"The correlation engine needs to be improved."
"The initial setup was not so easy, partly because the documentation was not up to date."
"There should be more opportunity for community kind of distribution where, for example, if there was a zero-day threat targeting companies."
"IBM technical support is always terrible."
"The initial setup requires that you have somebody with the proper skill set, and it would help if the configuration were easier."
"It's resource-intensive."
"I think that the search speed of this solution could be improved."
"The reporting system could use some upgrading."
"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."
"Whenever we are upgrading or installing any type of patch, at that time we have some delays."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"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 the community version, which can be used for free."
"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 an open-source solution."
"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."
"OSSIM is free."
"AlienVault OSSIM is expensive compared to its competitors."
"QRadar's price is reasonable compared to LogRhythm."
"There is an annual license required for this solution."
"Our licensing costs for this solution is on a yearly basis."
"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."
"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."
"The price of this solution is a little high."
"The pricing is good."
"The solution has a licensing model that is based on events per second so it scales to need and budget."
