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.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.

Quotes from Members

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

Pros

"Technical support is excellent; they are very helpful and responsive."
"What I like about this product, is that it is a fully-fledged solution."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The solution is free to use."
"I recommend it due to the experience of the people running it."
"The paid version of the solution has reporting and better scalability options."
"There are a lot of people you will find using OSSIM since they are also offering OTX as a service"
"The log management has helped to improve my organization."
"Our primary use case for this solution is detecting issues to provide customers with information."
"It is stable."
"I have made use of technical support and am certainly very satisfied with them."
"The initial setup is straightforward"
"ManageEngine EventLog Analyzer is useful for log and alert correlation and is a full-function SIEM solution."
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"The user interface is very good."
 

Cons

"The solution is not scalable."
"The user interface needs to be friendlier across the board."
"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."
"It's under heavy traffic. If you have heavy traffic, the system is slow."
"I would advise others to not implement it for any enterprise-level organization."
"The initial setup was not so easy, partly because the documentation was not up to date."
"The solution needs more integration with cyber intelligence systems. Our customers want to use a single tool for managing cybersecurity."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"The scalability is limited."
"The solution is stable. However, there are limits. For example, we can do 2,500 Syslog events per second, but if we want to do more we have to install the distributor structure, and then we can expand how many events we can do. They could improve the stability."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
"The first tier of customer service and support is not great, and additional upgrades could be included."
"Support could improve to make the solution better."
"I would like to see more detailed reports."
"The solution should improve on its log capturing capabilities, the authentication, when a person logs onto a network device."
 

Pricing and Cost Advice

"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."
"AlienVault OSSIM is an open-source solution."
"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 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 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."
"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."
"AlienVault OSSIM is expensive compared to its competitors."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"There is a yearly subscription for the solution."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"There is a license required for these solutions. The customer can choose the license type, such as an annual license purchase or a perpetual license. If the customer wants maintenance they will have to pay annually."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
