Uptime monitoring that never leaves your network.

Tessera runs as a Windows service on your own hardware — HTTP, TCP and PING checks, a real-time dashboard, TLS-certificate expiry alerts, and email / webhook notifications. No third-party cloud. No per-monitor surprises.

Features

Everything you need to watch your infrastructure

Purpose-built for teams that keep monitoring in-house.

Multi-protocol checks

HTTP, TCP and ICMP ping with per-target intervals and failure thresholds.

Control-room dashboard

Real-time status, latency graphs, and problems-first views that stay fast at thousands of endpoints.

TLS certificate monitoring

A validating probe warns you days before a certificate expires — with the exact reason on the target.

Instant alerting

Email and webhooks — wire to Slack, Zapier or SMS — the moment something goes down or recovers.

Self-hosted & private

Installs on your Windows server; monitoring data never leaves your network.

Users, roles & audit

Admin/viewer accounts, a full audit log of every change, and a severity-levelled diagnostic log.

Tags & fast filtering

Organize and search thousands of targets with server-side search, tag filters and pagination.

One-installer setup

A native Windows installer; runs as a service and survives reboots.

How it works

Monitoring in three steps

  1. 1

    Install

    Run one native Windows installer. Tessera registers itself as a service.

  2. 2

    Add targets

    HTTP, TCP or PING. Tag them, set check intervals and failure thresholds.

  3. 3

    Watch & get alerted

    Live dashboard, latency history, and email / webhook alerts on any change.

Pricing

Simple, per-target pricing

Priced by the number of monitored targets. Undercuts per-monitor SaaS at every tier.
