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

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."
"I have deployed it widely because I find that it gives value for money."
"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."
"AlienVault OSSIM is an enterprise solution that sells easily. It is rated highly by organizations."
"The most valuable features of AlienVault OSSIM are case management, ease of configuration, and investigation."
"This solution is very stable; it runs on a Linux box, you only interface with it through the GUI, it works behind the scenes, and it has never crashed in the time that I have used it."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"The open vault component and the checking of vulnerabilities are the most valuable features, and the page management helps with this, because if you know how your device is vulnerable at least you can do something about it."
"I have made use of technical support and am certainly very satisfied with them."
"The initial setup was very simple and straightforward, according to our security team."
"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 tool's reports show activities."
"The log management has helped to improve my organization."
"The initial setup is straightforward"
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
 

Cons

"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"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."
"ArcSight works better than AlienVault right now."
"Lacking in depth of reporting."
"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."
"The documentation could be improved."
"We need more dashboards and we need more customization for dashboards."
"The correlation engine needs to be improved."
"There isn't good security integration when it comes to cybersecurity. The correlation of logs isn't so simple."
"The customization of reports could be a lot easier. It is not difficult but it could be made easier."
"Support could improve to make the solution better."
"I would like to see more detailed reports."
"The first tier of customer service and support is not great, and additional upgrades could be included."
"It may not be as easy to use as Splunk."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"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."
 

Pricing and Cost Advice

"AlienVault OSSIM is expensive compared to its competitors."
"We are using the community version, which can be used for free."
"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."
"When comparing AlienVault OSSIM to Microsoft Sentinel, AlienVault OSSIM incurs additional costs due to its licensing price structure. If you are using AlienVault for security purposes at a certain level it can have a higher price point than the current pricing of Microsoft Sentinel."
"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 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 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."
"Licensing for ManageEngine EventLog Analyzer is paid yearly."
"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."
"There is a yearly subscription for the solution."
"ManageEngine EventLog Analyzer is a low-cost solution. It costs approximately $1,000 per month per server for a perpetual license."
"We paid for the license of the solution and the deployment. The price of ManageEngine EventLog Analyzer is less expensive than other solutions."
"ManageEngine EventLog Analyzer is expensive. Its licensing costs are annual."
