Proactive monitoring has improved uptime and now detects performance issues before users suffer

The user interface and configuration experience could be more modern and streamlined in some areas, especially when managing a large number of monitors or creating complex monitoring workflows. Better navigation, integration, and more intuitive customizations for the dashboard and alerts would improve the overall operational experience. Dashboard customizations and reporting flexibility represent another improvement area. More advanced visualization options and an easier way to create tailored operational dashboards would help the team analyze trends and share insights more effectively. The integration ecosystem could also be expanded further, especially for modern DevOps and cloud-native workflows. Stronger native integrations with collaboration tools, observability platforms, and CI/CD pipelines would make it easier to fit into the evolving engineering environment. It would also help to have more automation-friendly capabilities such as easier API-based configurations, management, and infrastructure as code support for monitor provisioning. That would make large-scale monitoring management more efficient for the DevOps team. From a support perspective, the experience has been generally stable, but faster turnaround times for more complex technical issues and more detailed troubleshooting guidance would be beneficial. Improved documentation and more advanced implementation best practices for enterprise-scale deployment would also help the team onboard and optimize the platform more effectively. AlertSite would benefit from continued modernizations in a few areas. The biggest improvement would be a more intuitive and modern user experience for configuring monitoring, managing alerts, and navigating dashboards, especially in larger environments with many monitored services. Stronger integrations with modern cloud-native DevOps ecosystems including better automation support, richer APIs, and easy integration with CI/CD pipelines and observability platforms would also be helpful. Another improvement area is intelligent alert management. Features such as smart alert correlations, anomaly detections, and noise reduction would help operations teams focus on the most critical incidents more effectively.

Helps reduce response time but has room to improve customization complexity

We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Quotes from Members

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

Pros

"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."

"This solution has numerous advantages; it's extremely simple to configure, and either digital monitors or single-URL monitors are simple to configure and build."

"I highly recommend AlertSite to other users."

"The return on investment of this solution is well witnessed in our organization because of the integration and various capabilities that it offers to interact with the upstream or downstream systems."

"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis."

"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."

"The alerting capabilities of AlertSite were really helpful."

"There are custom reports available along with the inbuilt reports."

More AlertSite pros

"The monitoring capabilities of the product are excellent."

"It is a great product; the SNMP protocol tracking feature is good, I really like how it tracks SNMP, and the alerts are also great."

"The most valuable feature is that it provides network segregation for server monitoring."

"The level of discovery-based configuration that lets us auto-configure the monitoring for various systems is a valuable feature."

"We use it to monitor and manage our servers."

"Zabbix can use old data to current data to set the threshold. We can use previous data to set the threshold."

"Every new asset placed in the environment can be automatically detected, predicting human failures."

"It's very easy to use and manage."

More Zabbix pros

Cons

"AlertSite requires improvements related to security, even at the enterprise level."

"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."

"One area that needs improvement in AlertSite is the slow UI. I'm using the classic UI because it's quite user-friendly, or in human-readable format, but it's a little slow. It takes time to load all the monitors, so if that could be sped up, that would be helpful. The AlertSite support team also needs improvement in terms of availability. Most of the agents in the team aren't available 24 x 7, so if there's something you need to discuss, you need to tell the support team ahead of time to schedule it. Multiple times, when a case comes up during weekends or whenever my team is doing an update, support needs improvement, availability-wise. I use AlertSite for synthetic monitoring, so whatever is available right now is okay, but if I want to request a new feature on a website, currently, the UI refreshes automatically. I would like to have the option on AlertSite to configure that manually. The UI auto-updates every few minutes, so if I can control that manually, that would be helpful."

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation. If there's a specific activity you want to do, you can't even find information on how to do it, so you have to contact the AlertSite support team to assist you, and only then would the issue be resolved. At the moment, it's not easy to find or get full documentation on how to deal with different issues. You always have to go back to AlertSite support and get help. The documentation for AlertSite could be improved and it's what I'd like to see in the next release of the tool because at the moment, the documentation isn't complete, so you'll have to contact support, but contacting support isn't an issue because the team responds to you quickly."

"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."

"The user interface and configuration experience could be more modern and streamlined in some areas, especially when managing a large number of monitors or creating complex monitoring workflows."

"In terms of support, it is all based on the cost of the subscription that our company purchased, but it wasn't great, and it could've been much better."

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."

More AlertSite cons

"There's a small module of APM, however, it is not an enhanced version. People usually ask for a full-fledged APM solution."

"Zabbix has it all except for predictive trending."

"The event correlation could be better."

"The reporting is lacking because this is an open-source tool, and nowadays, management's expectation is that the reports should be of high quality and every information should be presented in a concise manner."

"The graphical user interface could be customized a little bit more, and also the dashboard could be more friendly."

"Zabbix technical support is sold separately."

"The user interface could be a bit better. They could update it a bit."

"Multitenancy."

More Zabbix cons

Pricing and Cost Advice

"The cost is high."

"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."

"We purchased the license once and had the option of selecting the number of user licenses."

"Zabbix is free but if you use it in production then you have to pay for it."

"The tool's licensing is good."

"We’re using the free version, which covers all our current needs."

"The solution is open source so is free."

"The tool's licensing costs are yearly."

"It is a true open-source solution, so there are no licensing costs."

"If you have 20,000 hosts, the support costs around €95,000 for a year."

"We are using the free, open-source version."
