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.

The solution is a consistent logging platform that provides excellent query mechanisms
We can query a lot of data points and build dashboards. The vendor is good at adjusting their models. Most companies want us to forecast our yearly use and pay it upfront on day one. With Logz.io, we commit to use 14 TB in a year. However, they measure us every month and give us a monthly bill. Depending on our monthly usage, we pay for 14 TB divided by 12 months or a little extra. It's a little bit more like AWS. Other solutions do not do it. They want their money upfront. We really like the dashboards. We have 36 sub-accounts. Each sub-account is an app, and we could put restrictions on that app. Previously, there were capacity restrictions on the sub-accounts. If we have a sub-account of 1 TB and use only 100 GB, we waste 900 GB that day. We could not share it between sub-accounts. Now, they provide an overhead volume. We do a reserve, and any sub-account could use anything over the reserve. It utilizes our footprint better.

Quotes from Members

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

Pros

"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."
"Technical support is excellent; they are very helpful and responsive."
"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 threat policies of the solution are always very advanced and the best in the market, and they are very persistent in terms of keeping up with security protocols."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"The solution is free to use."
"I have worked with LogRhythm in the past, since 2015, and I find that AlienVault is a better product."
"The paid version of the solution has reporting and better scalability options."
"We use the tool to track the dev and production environment."
"The tool is simple to setup where it is just plug and play. The tool is reliable and we never had any performance issues."
"The visualizations in Kibana are the most valuable feature. It's much more convenient to have a visualization of logs. We can see status really clearly and very fast, with just a couple of clicks."
"I can't imagine how I ever worked without it before."
"The visualizations in Kibana are the most valuable feature; it's much more convenient to have a visualization of logs, and we can see status really clearly and very fast with just a couple of clicks."
"We use the product for log collection and monitoring."
"The other nice thing about Logz.io is their team. When it comes to onboarding, their support is incredibly proactive. They bring the brand experience from a customer services perspective because their team is always there to help you refine filters and tweak dashboards. That is really a useful thing to have. Their engagement is really supportive."
"The query mechanism for response codes and application health is valuable."
 

Cons

"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"I don't like to work on OSSIM because it is unpredictable."
"They can add more compliance templates."
"AlienVault OSSIM failed to provide our company a full insight, while also giving out a lot of false positives."
"Sometimes it takes very long for your issue to get resolved."
"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."
"Sometimes technical issues take very long to get resolved."
"It's so hard to configure and explore something new on it."
"When there are bugs in Logz.io, it increases our troubleshooting time by 200 percent or more."
"I would like granularity on alerting so we can get tentative alerts and major alerts, then break it down between the two."
"The solution needs to expand its access control and make it accessible through API."
"The price can be cheaper and they should have better monitoring."
"Capacity planning could be a little bit of a struggle."
"When it comes to reducing our troubleshooting time, it depends. When there are no bugs in Logz.io, it reduces troubleshooting by 5 to 10 percent. When there are bugs, it increases our troubleshooting time by 200 percent or more."
"I would like them to improve how they manage releases. Some of our integrations integrate specifically with set versions. Logz.io occasionally releases an update that might break that integration. On one occasion, we found out a little bit too late, then we had to roll it back."
"I would like granularity on alerting so we can get tentative alerts and major alerts, then break it down between the two, but they do have a lot of good alerting stuff in there already."
 

Pricing and Cost Advice

"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."
"OSSIM is free."
"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."
"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 OSSIM is expensive compared to its competitors."
"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."
"The solution is open source, so it's free to use."
"At the time it was set up, we thought Logz.io was very reasonable for what we were getting in terms of how much time and hosting costs it was saving us, because you don't have to run the servers for it anymore."
"You pay for what you need, and that is a good model. They are also quite happy to talk to you about your uses and your use case. They will even go as far as suggesting things that you don't need to do in order to save you money. At one point, I was quite surprised at how cheap it could be if we wanted it to be or how much they would help us manage our costs."
"The product is a little expensive."
"The product's pricing is cheaper than other solutions."
"The tool is an open source product."
