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.

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

"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"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 most valuable features of this solution are the data correlation and vulnerability assessment."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"It is a perfectly nice and free tool for compliance testing, assessment, and some basic vulnerability."
"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."
"Network traffic analysis is highly efficient."
"Technical support is excellent; they are very helpful and responsive."
"The scalability of SolarWinds Security Event Manager is good."
"The product's most effective part in improving security stems from the fact that the solution is deployed for event management, log viewing, and information management."
"It performs network behavior monitoring, log monitoring, and disaster recovery monitoring."
"User-friendly configuration is key, and the configurations are simple, not complex."
"The graphical user interface is very user-friendly. SolarWinds is a hybrid solution so you can use it across many platforms."
"If you have no monitoring tool in place, SolarWinds SIEM is a good place to start and very inexpensive."
"The most valuable feature of the solution is intuitivity of navigation; it's easy to build rules and actions which are based on the logs and event types we collect with the software."
"Technical support for this solution is good."
 

Cons

"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"We need more dashboards and we need more customization for dashboards."
"I don't like to work on OSSIM because it is unpredictable."
"The log collection is okay, but tracing the logs or tracing the events is a bit difficult."
"The biggest thing I always complain about is that the user intake is a very old version."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"AlienVault OSSIM should improve the deployment and make it unified like the USM."
"GUI could be improved."
"I think the customization area in the tool can be considered as an area of concern where improvements are required."
"The product should improve the ease with which you can create event alerts. They are not as hard now but you need to have an easier way."
"The solution was a little slow when running some larger queries."
"We used the support from SolarWinds Security Event Manager and they are knowledgeable but challenging to get in contact with them."
"The reporting could be more robust. It can be a lot more granular and that will make it a lot more useful in comparison to how it is incorporated at the moment."
"It can be difficult for users who are inexperienced with the solution."
"The company had to use a third party for the implementation of the solution."
"There are no multiple dashboards which would allow you to see information side-by-side."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"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."
"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 an open-source solution."
"We are using the community version, which can be used for free."
"AlienVault OSSIM is free."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"The solution is open source, so it's free to use."
"It is in the appropriate mid-range. It is not as expensive as some of the other solutions. It is also not cheap."
"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 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."
"The pricing model would benefit from having package deals with other SolarWinds products."
"The price of SolarWinds Security Event Manager is reasonable."
"Licensing is on devices, so if you have many, then this may be high."
"Licenses can only be purchased in blocks of fifty at a time."
