Enterprise-level monitoring facilitates global observability and seamless script creation with intuitive tools
SmartBear, as a vendor, is focusing more on API management and testing rather than monitoring. AlertSite could benefit from more future-focused innovation, especially with competencies in generative AI. Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7. Outside of critical platform issues, there's no continuous support available.

A reliable solution for SSL offloading and to encrypt outside traffic
If you are responsible for monitoring the logs in F5, it isn't very easy. The format is complicated compared to different vendors. For example, Fortinet and Cisco have feasible formats for sending and fetching logs. Suppose I'm monitoring the logs and everything, and when I am retrieving logs from F5, I want to know whether it is regular traffic or any abnormality is happening. The logs itself is not user-friendly. It may not give you a clear way of what's happening. You have to go through different websites and work on it. You have to waste so much time on it.

Quotes from Members

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

Pros

"The alerting capabilities were really helpful."
"The alerting capabilities of AlertSite were really helpful."
"There are custom reports available along with the inbuilt reports."
"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."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."
"The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."
"From our experience, it really helps managers in measuring application SLAs and viewing historical performance data."
"Each had strengths in one area or another, but CA covered the majority of our needs end-to-end."
 

Cons

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."
"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."
"It is not compatible with all of the product platforms that we use."
"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."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"I could use a few changes to the user interface."
"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."
"The RBMS component is limited as you can only record using Internet Explorer."
"Pricing makes little sense. We had examples where it would be cheaper to have two basic accounts than one intermediate."
 

Pricing and Cost Advice

"The cost is high."
"We purchased the license once and had the option of selecting the number of user licenses."
"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."
