It is used by the IT department only.
  • Monitoring up-time.
  • Transaction checks.
  • The pricing model is very pricey when compared to alternatives.
  • Lost of upfront costs.
Ideal for medium to large scale monitoring. Pricey for smaller organizations.
I've been unable to contact support after several attempts.

AlertSite is used across our whole company to monitor our websites and web applications at the real browser level to collect super important metrics reflecting web page load time but from the user point of view. That approach helps us to understand what our website users are experiencing in real-time.
  • Intuitive and almost instantaneous creation of monitors.
  • Performance bottlenecks alerts in real time.
  • Sophisticated transaction monitors are hard to maintain.
  • Integration with Splunk can cause problems.
AlertSite works exceptionally well if you need to analyze how your digital assets perform over time and, based on provided reports, determine the potential slow down root cause to make data-driven decisions instantly. In case you are used to analyzing by visually representing your availability and performance, AlertSite might not be the perfect solution for you.
What we have noticed so far is the fact that AlertSite customer support team is trying to build relationships and go the extra mile to make sure we can overcome any occurring issues. They are quick to respond and provide sufficient guidance about how to implement product features efficiently, integrate new tools, and fix product issues.

We needed a solution at the time to replace a very aged website monitoring solution. Our websites were developing constantly we weren't keeping up with the changes in terms of monitoring the visibility of the applications and the multistep experiences users were undertaking during a site visit and using our products. We have a large userbase and our websites are where our products are available, making us a 24/7 operation and also meaning our website uptime is absolutely key to profitability.
  • The Deja-Click Recorder is an excellent tool.
  • Good UI that translates to large NOC screens well.
  • Easy Alerting and Reporting.
  • Support is inconsistent at times in terms of quality and response.
  • Monitoring locations would have issues.
  • Dashboard would go unavailable at times or lag behind.
A very costly platform if you intend to implement multistep transactions that use geographical testing. There are better alternatives out there at a fraction of the cost. It's difficult to say where Alertsite would be well suited. They're experienced in the sector and have been a player for a while now so they have the experience to hand if you're new to transactional testing and just starting out. If you need a large number of transactions and have a wide variety of products to monitor, then this is not the solution for you, as the cost will scale.
