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.

Log analysis has become faster and more accurate, enabling precise threat detection

Regarding areas for improvement in Singularity Platform, I would say the data security posture and control over sensitive information could be enhanced. If the control were more robust, then it would be better. For instance, when I analyze a log using Singularity Platform, the logs I see are clear, but if they were more descriptive, it would be much better. For example, when I find a log suspicious, if it automatically points out that a particular point in the log at a specific timing or frame is looking malicious, it would be easier for me. I would not have to go through many logs to find this information.

Quotes from Members

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

Pros

"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."

"Inbuilt IDS, inbuilt integration with threat intelligence platform and with vulnerability assessment modules."

"Asset discovery is good."

"The most valuable feature is the logging capability."

"Better than other SIEM solutions because almost everything can be integrated."

"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 paid version of the solution has reporting and better scalability options."

"The initial setup was straightforward. I didn't have any problems."

More AlienVault OSSIM pros

"I have tried some paid tools, but I have found that Singularity Platform is far better than others, and as a log analyst and SOC analyst, I find it better than others."

"Singularity Platform allows us to have one single view of potential threats and the health of our environment, helping us optimize operational efficiency."

"The main benefits the end-user gets from Singularity Platform are, first, the program itself being very small, and then we get better output from applications running on their systems."

"Once it fully adapts to the environment, customers don't even need to monitor their endpoint protection landscape, as it can automatically learn and mitigate any threats or problems with minimal human interaction."

"I believe Singularity Platform is perfectly fine overall."

"The best feature of Singularity Platform is that everything is unified in one platform, which would be a main unique selling point for them."

"The best features I and my clients like the most about Singularity Platform are that, first of all, it's easy to handle, it doesn't take a lot of time to get into, there's no real obscurity, it takes a load of work from the team, and in most cases, you can literally just configure it once and leave it running until something comes up, and it will just work."

"Singularity Platform's real-time personalization feature has helped our customer experience strategies by allowing us to have different workspaces where we have custom views, and depending on the use case because we have many products that use Singularity Platform, they interact with the UI in different ways, producing different elements and giving us tailored views for different products."

More Singularity Platform pros

Cons

"AlienVault OSSIM could improve by having better integration with some of the newer tools."

"We need more dashboards and we need more customization for dashboards."

"There are somewhat more false positives with the user behavior analytics, which could benefit from an additional machine learning model to detect user patterns more rapidly."

"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."

"The initial setup was not so easy, partly because the documentation was not up to date."

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."

"ArcSight works better than AlienVault right now."

"The solution needs more integration with cyber intelligence systems."

More AlienVault OSSIM cons

"From an operational perspective, the customizable dashboards are easy to use, but I face concerns with the alerts from the email ticketing system."

"Technical support from SentinelOne is somewhat dependent on the engineer you are assigned. Some TAC cases are solved in a good time, but some cases faced challenges because the engineer was not competent or was not able to understand the issue or take it to its logical conclusion."

"The areas that have room for improvement in Singularity Platform include the fact that I am really not happy with the vulnerability management."

"For improvement, I would say the infrastructure is very slow; the application I use is sluggish, potentially due to workload or problems on my company's side."

"Sometimes, these customized solutions our developers develop also get flagged in real time, and the processes get stopped and are blocked, and we have to whitelist the processes."

"The first thing I would say about the negative side of Singularity Platform is that it lacks some customization and integrations compared to competitors."

"Regarding the pricing, Singularity Platform is very high compared to other platforms that have been worked with, such as CrowdStrike and other Sophos EDRs."

"In my opinion, the real-time monitoring capabilities in Singularity Platform sometimes work and sometimes they don't, because there are a lot of false positives and people use unsigned applications which get deleted or quarantined by the product."

Pricing and Cost Advice

"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."

"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 solution is open source, so it's free to use."

"We are using the community version, which can be used for free."

"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."

"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."
