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.

Centralized logs have improved troubleshooting and now reduce production incident impact
Logz.io can be improved by adding more AI-assisted root cause analysis and by improving log retention flexibility. They can also provide additional dashboard customization options. Logz.io is a very mature and grown platform with very good features. Most improvements should be around automation, AI-driven insights, and cost visibility. Because Logz.io is a very mature and grown platform that is very good, cost optimization can be made for higher costs related to higher log volumes. For larger organizations, custom dashboards can be improved. In terms of root cause analysis, there can be more AI-assisted root cause analysis capabilities.

Quotes from Members

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

Pros

"Asset discovery is good."
"OSSIM is the only solution that includes the large number of modules that we need: a vulnerability scanner, a network IDS system, a host IDS system."
"AlienVault OSSIM's GUI is very user-friendly."
"The initial setup was straightforward. I didn't have any problems."
"The product is majorly used for threat detection of the agents on servers and endpoints."
"The paid version of the solution has reporting and better scalability options."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"With AlienVault you get everything in one box."
"Our team doesn't spend time setting up, managing, and tuning a logging platform, which frees them up to spend time on higher value pieces of work and allows our people to focus on the high-value business change work."
"I can't imagine how I ever worked without it before."
"We use the tool to track the dev and production environment."
"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."
"Logz.io has impacted our organization very positively."
"The query mechanism for response codes and application health is valuable."
"InsightOne is the main reason why we use LogMeIn. This is mostly because of log data that we are pushing tools and logs in general."
 

Cons

"AlienVault OSSIM gives unwanted notifications."
"The documentation could be improved."
"I don't like to work on OSSIM because it is unpredictable."
"The main area where the AlienVault product was lacking around the 2018 timeframe was in its ability to scale."
"There needs to be more support or some kind of training program so users can self-learn the system more effectively."
"The initial setup was a bit complex. You've got to do a lot of reading. It's not an intuitive implementation."
"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."
"AlienVault OSSIM could improve by having better integration with some of the newer tools."
"Capacity planning could be a little bit of a struggle."
"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."
"The solution needs to improve its data retention. It should be greater than seven days. The product needs to improve its documentation as well."
"The product needs improvement from a filtering perspective."
"The solution needs to expand its access control and make it accessible through API."
"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."
"The price can be cheaper and they should have better monitoring."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"The licensing fees for the non-community edition are paid on an annual basis, and there are no costs in addition to this."
"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."
"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."
"AlienVault OSSIM is an open-source solution."
"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."
"The tool's licensing costs are yearly."
"The product is a little expensive."
"The tool is an open source product."
"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."
"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."
"The product's pricing is cheaper than other solutions."
