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.

Has supported client needs efficiently but requires deeper analysis features and faster support
The log analyzing capability of SolarWinds Security Event Manager should go into more depth than the current environment. More modification and enhancements are required on the dashboard side in order to make it closer to optimal performance. From observation and feedback from users, they need more functionality related to monitoring, and in-depth analyzing needs to be improved.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The most valuable features of AlienVault OSSIM are vulnerability assessment, network intrusion detection system, response to critical events, and awareness of the whole network."
"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."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"Better than other SIEM solutions because almost everything can be integrated."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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 of SolarWinds Security Event Manager is the analysis and the knowledge about the incidence that we trace."
"This tool is simple to use."
"User-friendly configuration is key, and the configurations are simple, not complex."
"The pricing was low, around 30K so ROI is less than one year."
"The out of the box reports and dashboard. It was easy to trim down these windows to something we could quickly use."
"Some of the rules are most valuable because you can be notified about various things, such as spyware or things that are going on in the internal network."
"SolarWinds is effective for server, network, and log monitoring. It's also good for IP address management. We also have a patch manager, but we're still working on getting that operational."
"It will identify things in your network that you just didn't know were going on."
 

Cons

"The biggest thing I always complain about is that the user intake is a very old version."
"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."
"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."
"Sometimes it takes very long for your issue to get resolved."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"The correlation engine needs to be improved."
"The documentation could be improved."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"The solution's technical support is okay, but we don't have an SLA, and sometimes the response times are very slow."
"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."
"The solution was a little slow when running some larger queries."
"The query capability in this solution needs improvement."
"I think the customization area in the tool can be considered as an area of concern where improvements are required."
"We'd like more customization capabilities."
"It takes a long time to perform a root cause analysis."
"We need to post events on the end of the devices. Sometimes, the event does not respond."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is expensive compared to its competitors."
"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."
"We are using the community version, which can be used for 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."
"The tool's licensing costs are yearly."
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."
"Licenses can only be purchased in blocks of fifty at a time."
"The tool is available at a good price for customers compared to other solutions in the market. I rate the product's price as an eight out of ten."
"We do a yearly license renewal. For a year, the solution costs roughly $500,000 USD. There are no costs beyond this yearly fee."
"The price of SolarWinds Security Event Manager is reasonable."
"The pricing model would benefit from having package deals with other SolarWinds products."
"Licensing is on devices, so if you have many, then this may be high."
