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.

AI-driven observability has reduced investigation time and now improves uptime and customer trust

As for improvements needed in Logz.io, I think cost or pricing is always a consideration, especially since I come from a startup and an Indian company, making us look for products that provide better value for money. Compared to the market, their pricing appears decent but might need reevaluation as we scale further to remain competitive. The main concern for me is pricing, as feature-wise, I believe Logz.io is on par with other tools available in the market; however, it is not as widely discussed. Their features align with offerings from Elastic Stack and other prominent tools, including functionalities available from Prometheus or Grafana, providing centralized logging and other capabilities in the UI, so while the product direction is solid, improved pricing would immensely benefit us. I believe we have covered almost everything regarding improvements needed for Logz.io.

Quotes from Members

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

Pros

"AlienVault OSSIM's GUI is very user-friendly."

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

"The initial setup is straightforward."

"A very good feature of AlienVault OSSIM is that it has many domains that can be integrated from different solutions."

"You can customize the dashboards as well as the reporting."

"The most valuable features of this solution are the data correlation and vulnerability assessment."

"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."

"Network traffic analysis is highly efficient."

More AlienVault OSSIM pros

"Logz.io has impacted our organization very positively."

"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."

"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."

"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 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."

More Logz.io pros

Cons

"The user interface could be improved."

"The correlation engine needs to be improved."

"It's under heavy traffic. If you have heavy traffic, the system is slow."

"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."

"The incidence reporting could be better."

"I would like the solution to be able to integrate with my firewall, my IDS and my Honeypot solutions so that it can provide real-time reporting as things occur and then have alert sent to me on my phone when suspicious activity is happening."

"There needs to be more focus on the NOC and IIS in terms of developing applications for behavior detection."

"Sometimes it takes very long for your issue to get resolved."

More AlienVault OSSIM cons

"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."

"However, at this lower scale, we feel it does not deliver the expected value for the money we are paying, reiterating my concern about cost."

"The solution needs to improve its data retention. It should be greater than seven days. The product needs to improve its documentation as well."

"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."

"Capacity planning could be a little bit of a struggle."

"The solution needs to expand its access control and make it accessible through API."

"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."

More Logz.io cons

Pricing and Cost Advice

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

"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 free."

"AlienVault OSSIM is expensive compared to its competitors."

"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."

"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."

More AlienVault OSSIM pricing and cost advice

"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's pricing is cheaper than other solutions."

"The product is a little expensive."

"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 tool is an open source product."
