Unified Platform for Proactive Monitoring and Alerting

API Monitoring

Make sure your internal, external and third party APIs are available, return the correct payload and are performing as expected.

Web App Monitoring

Monitor your web sites and applications using real browsers just like a customer with almost any action. No scripting required.

Mobile Monitoring

Monitor your mobile enabled web sites, native mobile apps with real devices, carrier based nodes and network speeds (3G, 4G LTE).

Transaction Monitoring

Monitor multi-step transactions and business processes from where your end users are - across the world or behind your firewall.

If response time varies by even a tenth of a second, I know that’s a half of dozen questions we’ll need to answer. So, AlertSite is a key indicator of performance related issues within our infrastructure, especially during the holidays.
