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

"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."
"It has helped us remediate threats in the past by providing significant events that assisted in identifying suspicious activities, such as logins from multiple countries."
"The threat alerts it gives me from time to time on harmful code within the network, or if they are generating any network traffic, are very useful."
"The tool's security detection is good. It helps us with login tracking and generating reports. We aim to identify potential issues, such as brute-force attacks on user accounts or server-level anomalies. For instance, if I receive a report indicating a server is at an abnormal level, I investigate and address the issue."
"The solution has a very good open source community, and whenever we have problems, we are always able to resolve it online."
"The solution is very stable, and compared to QRadar and Splunk, it's very stable."
"Network traffic analysis is highly efficient."
"The paid version of the solution has reporting and better scalability options."
"We use the tool to track the dev and production environment."
"The query mechanism for response codes and application health is valuable."
"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."
"I can't imagine how I ever worked without it before."
"It is massively useful and great for testing. We can just go, find logs, and attach them easily. It has a very quick lookup. Whereas, before we would have to go, dig around, and find the server that the logs were connected to, then go to the server, download the log, and attach it. Now, we can just go straight to this solution, type in the log ID and server ID, and obtain the information that we want."
"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."
"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."
 

Cons

"I would advise others to not implement it for any enterprise-level organization."
"From a management console perspective and the maturity of the dashboards, I would probably put it slightly behind some of the other players that have been in the market for ages."
"They can add more compliance templates."
"The user interface could be improved."
"It's so hard to configure and explore something new on it. It is not easy to find the steps we need to follow in order to use the solution effectively."
"AlienVault OSSIM’s configuration and integration could be a little easier."
"The solution is not scalable."
"GUI could be improved."
"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 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 price can be cheaper and they should have better monitoring."
"Capacity planning could be a little bit of a struggle."
"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 solution needs to expand its access control and make it accessible through API."
"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."
 

Pricing and Cost Advice

"The solution is open source, so it's free to use."
"AlienVault OSSIM is expensive compared to its competitors."
"AlienVault OSSIM is an open-source solution."
"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."
"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."
"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."
"We are using the community version, which can be used for free."
"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."
"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 is a little expensive."
"The tool is an open source product."
"The product's pricing is cheaper than other solutions."
