The only SMB monitoring platform with a zero-privilege server agent, built-in security scanning, UK/EU data residency by default, and predictable usage-metered pricing. No Datadog bills.
Most tools do one thing. WatchTower 15 combines external uptime monitoring, deep server instrumentation and active security scanning — giving your team a single source of truth.
Know before your users do. External checks against your domains, SSL certificates and hosted services — every 60 seconds, from UK/EU infrastructure.
Deploy in 30 seconds, root-free. The wt15-server-agent installs as an unprivileged user with zero Linux capabilities — unprecedented in the SMB monitoring space.
Not just uptime. Built-in SSL/TLS analysis, DNS anomaly detection and domain expiry alerting give your team a security posture it can actually maintain. No SIEM required.
Every capability listed below is standard — not a paid add-on, not an enterprise feature, not a separate licence.
NoNewPrivileges=yes, ProtectSystem=strict, zero Linux capabilities at install. The agent literally cannot escalate. Datadog and Dynatrace both require Linux capabilities at install time — WatchTower 15 requires none.
Your monitoring data lives in the UK/EU without extra configuration, extra cost, or a separate support tier. Datadog gates EU residency behind a premium plan. We make it the default for every customer.
SSO and full audit logs are bundled in — no enterprise plan required. Better Stack charges approximately £200/mo for audit logs and £4/user/mo for SSO. WatchTower 15 includes both from day one.
SSL cert analysis, DNS anomaly detection and domain expiry alerts are built in. UptimeRobot, Freshping and Pingdom only check cert expiry. No other SMB uptime tool offers the full security-scan breadth WatchTower 15 provides.
cgroup v2 makes /sys/fs/cgroup world-readable. WatchTower 15 reads container CPU and memory stats without mounting the docker socket — which is root-equivalent access. Every competitor gates this behind privileged access.
Usage-metered per monitored resource. No per-seat multipliers. No per-feature paywalls. No EU residency tax. One predictable line item per month, however many users you have on the platform.
We stack up against the tools your team is most likely evaluating — from the SMB uptime players through to the full observability platforms.

A 10-server, 5-user team monitoring with Datadog can easily exceed £600/mo before data charges. WatchTower 15 charges only for the resources you monitor.

Server, domain and security monitoring with UK/EU residency by default, zero-privilege instrumentation, and a bill that only grows with the resources you actually monitor.
