See real service performance
from every critical location
WatchTower continuously probes your websites, APIs, DNS, network paths, certificates and database dependencies from multiple geographic locations — and catches degradation before your customers complain.
One platform for end-to-end service quality
Active probing from user locations and critical network points — turning real user experience into data you can measure, alert on, and trace.
Multi-location probing
Scheduled checks from multiple geographic nodes for websites, APIs, DNS resolution, network reachability, file downloads and certificate validity — the real user's point of view.
User-perceivable metrics
Track response time, resolution latency, connection time, TLS handshakes, time to first byte, download speed, packet loss and routing hops — every experience, quantified.
Dashboards & SLO reports
Trend analysis, regional comparisons, availability and latency reports — prove your service level to teams and customers with evidence, not anecdotes.
Actionable alerts
Rules-based notifications for failures, slow responses, packet loss, certificate risks and connectivity anomalies — routed to the right team with minimal noise.
Reliable collection at scale
Built on reliable message queues and high-performance databases for stable collection, storage and querying of probe data at any scale.
Unified operations
Tasks, nodes, alert rules and team permissions managed in one place — configure once, apply globally. Distributed monitoring, made as simple as local.
Ping / TCP / DNS / MTR — full visibility
Not just "is it down?" — pinpoint the source: the target service, DNS, or the network path.
From firefighting to foresight
Detect before complaints
Catch performance degradation before your customers ever feel it.
Pinpoint the source
Quickly tell whether it's the target service, DNS, or the network path.
Trends, always visible
Availability, latency and experience metrics retained long-term.
Evidence-based alerts
Notify the right team with proof — fewer false alarms, faster response.
For every team that takes quality seriously
Built for operations, network and application teams that need cross-regional service quality evidence and distributed edge observability.
