Back to compare

Same category. Different depth.

This is the one comparison where the architecture is not the difference. Both work from the reports browsers already generate, and both avoid putting anything on your pages. What separates them is how far it goes once those reports arrive — whether you are left to write the policy, or taken to an enforcing one.

Reporting endpoint

URIports

Collects browser reports and presents them for review.

Client-side security platform

Report URI

Gets you to an enforcing policy, verifies script integrity, archives the code and alerts on change.

How To Read This

Written against the category, not a screenshot.

We do not publish a feature audit of another company's product. Feature lists change without notice, and a comparison that quotes them is out of date the day they do — which makes it a worse guide than no comparison at all. What follows describes what we do, alongside what collecting browser reports gets you at the baseline. Check the current state of anything you are evaluating for yourself; that is the only version of it that is ever accurate.

Collect and present

Browser Endpoint Dashboard

The reports arrive and you read them. Everything after that — deciding the policy, judging whether a script changed, keeping evidence — is yours to do.

Collect and act

Browser Report URI Policy, evidence, alerts

The reports feed a policy builder, a script archive, change detection and alerting, so the volume turns into decisions rather than a backlog.

Head to Head

What we build on top of the reports

Collecting reports is the easy half. The hard half is the volume: a policy of any size produces far more data than anyone will read, and a platform is judged on what it does with that.

Consideration	Baseline reporting	Report URI
Getting to an enforcing policy	Read the reports and write the policy yourself	CSP Builder and a wizard generate it from what browsers reported
Script inventory	Scripts appear as report values	Script Watch inventories them and flags first sightings and change
Script contents	Not collected — reports carry metadata	Fetched, hash-verified against the browser's fingerprint, archived
Data exfiltration	Visible only as blocked connections	Data Watch tracks what forms and endpoints your pages send to
Noise handling	Manual triage of extension and injected-script reports	Filtering, reputation gating and threat intelligence classification
Change detection	Notice it yourself, next time you look	Alerting on new scripts, changed scripts and policy drift
Report types	The main browser reporting types	Fourteen, including Integrity Policy and Connection Allowlist as they ship
PCI DSS evidence	Export the reports	A purpose-built evidence pack mapped to 6.4.3 and 11.6.1

Why It Matters Here

Nobody abandons this because the reports stopped arriving

Deployments stall for one reason: a policy in report-only mode generates thousands of violations, most of them browser extensions, and there is no obvious path from that pile to a policy anyone is willing to enforce. Everything below exists to shorten that path.

From Reports to Policy

The policy writes itself from what your visitors actually loaded

Run report-only for a week, and the reports describe your site's real dependency graph better than any inventory you could assemble by hand. CSP Builder turns that into a working policy, the wizard walks you from nothing to enforcing, and filters keep extension noise out of the way while you do it.

Evidence, Not Just Signal

When a third-party script changes, you get both copies

An alert saying a script changed is the beginning of an investigation. Two archived files you can diff is the end of one. Because the fingerprint comes from a real execution in a real browser, the copy we hold is provably the code that ran — which is what makes it usable as evidence rather than as a lead.

Track Record

Who runs this

Report URI has collected browser security telemetry since 2015. Have I Been Pwned has run on it for years, and our case studies cover several of the most examined client-side incidents in the industry — the British Airways and Ticketmaster Magecart attacks, the European Space Agency, and the cryptojacking compromises at the Information Commissioner's Office and the United States Courts.

The platform is built by people who work on the standards themselves, including Device Bound Session Credentials, passkeys and WebAuthn, with an open-source library published for the former. New report types are supported as browsers ship them, usually during the origin trial.
