How much does it cost?

Sentinel is free during early access. There is nothing to pay and no card to add. We will tell you before that changes, and you will see the price before you pay anything.

Can Sentinel break my server?

No. The agent is read-only and takes no commands.

Do you see my code or data?

No. We read health figures, and for app libraries only package names and versions.

You do not need to pay anything during early access.

Can I leave any time?

Yes. Not renewing ends it, and you can ask us to close the account.

How is this different from an uptime checker?

Website checks are the same kind. Sentinel also watches the server, checks security exposure, warns you about serious flaws in the software you run, explains alerts in plain language, and has engineers you can ask for help.

Where is my data kept?

On a server in Johannesburg, South Africa. We say so openly.

What you get

The important things, made clear.

A team that answers

Message real engineers from your dashboard; monitored-system help is included.

Security that watches

Same-day warnings for serious software flaws, exposed databases, waiting updates, risky SSH settings, and app-library vulnerabilities.

Know when something breaks

Website, page-word, port and ping checks, plus CPU, memory, disk, containers and traffic. Related alerts become one incident.

Cloud account health

Read-only checks for AWS, Azure, Google Cloud and Oracle; AWS needs no access keys.

Cloud spend

Live spend, forecasts and spike alerts are available on request during early access.

Alerts where you work

Telegram, email, Slack, Teams, Discord or a signed webhook.

Reports for your board

A 30-day view of incidents, fix speed and team work.

Built for Nigerian teams

Pay in naira-friendly ways without a sales call.

Security monitoring

Security that watches for you.

Urgent warnings, the same day

When a serious flaw is published in PHP, Node.js, Python, nginx, Apache, OpenSSL, Redis, PostgreSQL, MySQL and others, we tell you which of your servers run an affected version and what to update, before your operating system's vendor has shipped a fix.

Available on request during early access

The frameworks inside your apps

Laravel, Django, Express, Rails and the packages under them are checked against known flaws, read from your apps' lock files. We see package names and versions only, never your code.

The everyday things

Updates waiting, a restart that never happened, SSH accepting passwords, no firewall, ports open to the internet.

How it works

Sign up

Connect something

Connect a server by pasting one line, or enter a website address.

Relax

You are told in plain language, and told again when it is fixed.
