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.

Experience boosts operational efficiency while performance sees room for improvement
I don't have specific information on whether it was purchased on the AWS marketplace or somewhere else. I am working with Dynatrace Operator. I am also working with Algosec, Alluvio, CrowdStrike, Firemon, Gigamon Deep Observability Pipeline, and other solutions. I think it's a good tool, and I am satisfied with it. We have not stored cloud workloads with Gigamon Deep Observability Pipeline yet; we are still on-premises. The technical support takes about one to two hours to respond, which is acceptable. I am satisfied with the scalability of the product. The interface is good.

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."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"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."
"I highly recommend AlertSite to other users."
"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."
"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."
"It offers straightforward integration."
"The most valuable feature for improving network visibility with Gigamon is the packet filtering capability."
"The solution is straightforward to set up."
"It is a good product. It provides network visibility, which is important. Gigamon can bring some optimizations to my network. It is helpful for security inspection, and it makes my firewall work fast because my firewall doesn't have to do the inspection of the SSL connections, for example."
"It has high stability."
"The most valuable feature is NetFlow."
"The Pipeline's Comprehensive Insights into data flows have helped improve operational efficiency and security."
"The tool's most valuable feature is the encryption feature. From a security perspective, the solution hasn't significantly strengthened our security posture. However, it has greatly improved performance by streamlining encryption processes and avoiding encryption at multiple layers. This has also simplified troubleshooting, as we can whitelist certain processes."
 

Cons

"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"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."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"It is not compatible with all of the product platforms that we use."
"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."
"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 Gigamon Deep Observability Pipeline should have a feature showing the traffic flow within its platform. Currently, customers have to use separate tools for monitoring, which is inconvenient. If it had its visibility feature, it would make monitoring easier and more complete without needing extra tools."
"The security should be improved."
"They should increase the solution's cluster capacity."
"Its filtering feature needs improvement."
"The graphical user interface could be improved."
"In terms of improvement, while the initial setup is not overly complicated, we did encounter a few issues."
"It only inspects a specific kind of traffic. There should be different kinds of use cases."
"Gigamon Deep Observability Pipeline needs to improve its performance. I face issues with performance because we use SPAN, and the SPAN traffic is not good."
 

Pricing and Cost Advice

"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."
"The cost is high."
"The solution's price is reasonable."
"I would rate the solution as expensive, around an eight or nine out of ten. There are other competitive solutions available."
"The solution is highly-priced."
