For anyone responsible for someone else's website

You find out first. Not your client.

No more surprise call because something broke and nobody noticed. ReportGuard reports CSP violations, network errors and broken pages instantly — at one endpoint, for all your websites, GDPR-compliant in the EU.

Built by a developer who manages client websites himself — born out of daily practice.

What ReportGuard collects

Four error sources. One endpoint.

01

CSP Reports

Every blocked script, every violated policy entry lands with you instead of vanishing into the void. Spot injection attempts and broken embeds the moment they happen.

Content-Security-Policy
02

NEL Reports

DNS errors, TLS problems, timeouts: failures your server never sees — but your visitors' browsers report them anyway. ReportGuard collects them.

Network Error Logging
03

404 Monitoring

Dead links from outside, stale bookmarks, typos in campaign URLs: every 404 is counted and grouped by target — before rankings and visitors suffer.

HTTP 404
04

Custom Error Pages

Hosted error pages for any HTTP status code — not just 404. Every hit reports itself to ReportGuard automatically, no crawler or report-to snippet needed.

HTTP 4xx/5xx
How it works

Two headers. No snippets, no cookies.

STEP 1

Set the headers

Add two response headers to your website: Content-Security-Policy with a report target, and Reporting-Endpoints. No JavaScript, no consent banner required.

STEP 2

Reports come in

The ReportGuard endpoint accepts the browser reports, validates and archives them — cleanly separated per website, multi-tenant from the ground up.

STEP 3

Review and act

See new policy violations, clustered 404 targets and broken links per site at a glance — and fix the cause before it gets expensive.

Roadmap

Your own AI assistant will be able to ask ReportGuard directly.

Already using your own AI assistant and want it to keep an eye on whether your websites are up? ReportGuard is getting an integration your assistant can query on its own — instead of you having to check the dashboard.

MCP integration · in progress
GDPR & Hosting

Compliance isn't a feature here. It's the architecture.

ReportGuard was built for European website operators — not retrofitted for Europe afterwards.

Data stays in the EU

Operated on EU infrastructure. Your reports are processed without third-party services — no US cloud in the chain.

GDPR-compliant by design

Collection runs via response headers instead of tracking snippets: no cookies, no fingerprinting, full control over data and retention.

Full transparency on setup

You can see the complete header snippet for your website in plain text in the dashboard at any time — nothing runs hidden in the background.

Common questions

Before you ask.

Do I need a credit card for the trial?

No. The 30-day trial requires no credit card.

What makes ReportGuard different?

ReportGuard is EU-hosted and GDPR-native by default, with no opt-in surcharge for EU data residency. It's also getting an MCP integration so your own AI assistant can query site status directly.

What will it cost?

Planned at €9–89/month depending on number of sites.

Will it work with my own AI assistant?

Yes — an MCP integration is in progress so your assistant can ask for site status directly instead of you checking a dashboard.

Where is my data stored?

On EU infrastructure in Germany. Your data never leaves the EU, and no third-party processors are involved.
