Unified monitoring platform

You sleep.
FirstSI keeps watch.

Files, network flows, services, DNS, databases, software inventory, endpoint diagnostics: eleven monitoring modules in a single multi-tenant console. Deploy an agent, open the console, breathe.

Eleven modules, one console

Every blind spot in your IT,
covered by a module.

Turn on what you need, when you need it. No new server, no new console, no new password: it all lands in the one you already have. And what each module sees alone, the SIEM connects.

Pick a module

FileMonitor

Windows file access auditing: who read, modified or deleted what, when, and from which workstation. The agent reads the native audit log — no driver to install.

Native Windows auditingFilter by extensionBulk-deletion alerts

NetFlow

Continuous network flow analysis: conversations, volumes, protocols and abnormal traffic spikes. Your devices export, FirstSI aggregates and retains.

NetFlow v5/v9IPFIXsFlow

HostMonitor

Availability of your services and sites: HTTP, TCP and ping probes, incidents and response times. Maintenance windows keep false alerts out.

HTTP / HTTPSTCP & pingMaintenance windows

NetworkMonitor

Network infrastructure monitoring: SNMP devices, routers, tunnels and interfaces. Devices on a subnet are discovered automatically.

SNMP v2c / v3Routers & switchesVPN tunnels

SIEM

Cross-module event correlation: a file access followed by an unusual outbound flow becomes one incident, not two log lines.

Cross-module rulesConsolidated incidentsWebhook & email

DNSMonitor

DNS query monitoring and threat detection: malicious domains, tunneling, exfiltration. Often the first visible sign of a compromise.

Malicious domainsTunneling detectionExfiltration

AssetMonitor

Automatic software inventory with CVE vulnerability tracking and end-of-life alerts. You know what runs — and what should no longer be running.

SI-Map

Service mapping: who depends on what, inferred automatically from data you already collect. Before you stop a server, you know what stops with it.

DBMonitor

SQL Server and MariaDB performance: slow queries, wait statistics, blocking chains and instance health.

SQL ServerMariaDBSlow queries & blocking

SI-Tracer

Windows authentication tracing: who signs in where, from which machine, successes and failures alike. Out-of-hours logons surface on their own.

Logon eventsRepeated failuresOut-of-hours access

NetDiag

"Teams keeps dropping" and nobody knows why? NetDiag installs on the PC that suffers, measures every 15 seconds and returns a verdict: PC, Wi-Fi, VPN, line, DNS or service. Real Teams call quality, the Wi-Fi access point as UniFi sees it, traceroute and packet capture at the moment of the incident, a PDF report ready to share. And on uninstall, the PC is exactly as it was before.

How it works

Up and running in three steps.

1

Deploy the agent

One MSI installer for every module. The agent runs as a Windows service, is configured remotely and updates itself — with signed, verified updates.

2

Data flows in

Local collection with a built-in buffer: even if the link to the server goes down, nothing is lost. Everything resynchronizes automatically when the network returns.

3

You get alerted

Real-time alerts in the console, by email or by webhook. Thresholds, correlation rules and maintenance windows: you decide what deserves to wake you up.

Open to your tools

An API and an MCP server, included with every instance.

What FirstSI knows, your other tools know too: your ticketing tool, your global monitoring and, now, your AI assistants. Ask them a question in plain language, they query FirstSI and answer you. You decide what each tool may see, and every access is logged.

Security & compliance

A monitoring tool
that watches itself.

FirstSI handles sensitive data — it is built accordingly. Every secret is encrypted, every session is short-lived, every action is logged.

  • Strong authentication — MFA and WebAuthn (security keys), short-lived sessions with transparent renewal.
  • Encryption — secrets encrypted at rest, end-to-end TLS in transit.
  • GDPR compliance — personal data export and purge, full audit trail.
