Client-Side Security

Your website is running code you don't control

Third-party code executes on your website, creating a blind spot most security tools can't see. That code can change at any time, often without your knowledge. Report URI is a client-side security platform that shows you what's happening in the browser, enforces what's allowed, and proves it with real data.

The Problem

You control your code. But you don't control everything running on your site.

Websites and web applications rely on third-party code that runs in your users' browsers. You're still responsible for what runs, even when you can't see it, and that code can change at any time.

Control

You can't see everything running in your users' browsers

Third-party scripts run outside your control and can change without notice.

A tag you approved yesterday can load entirely different code today, especially through tag managers or external vendors.

Security

Your client-side attack surface is expanding

Attacks increasingly happen in the browser, where most security tools have no visibility.

Malicious or compromised scripts can skim data, inject content, or expose users — often through Magecart-style attacks that never touch your servers.

Compliance

You're expected to prove what's running in the browser

Standards like PCI DSS require visibility and control over scripts executing in the browser.

Without that visibility, you can't prove what's running or demonstrate that only approved scripts are allowed.

How It Works

Take control of what runs on your website

Report URI eliminates the blind spot created by third-party code, so you can address unknown risk, enforce what's allowed, and prove it with real data — without changing your infrastructure.

01

See what's actually running in the browser

Get a complete picture of what's executing on your site, including third-party scripts, dependencies, and unexpected changes. No assumptions. No guesswork.

02

Control what's allowed to run

Define what can run on your site and enforce it at the point of execution so only approved scripts are allowed, and everything else is blocked or reported.

03

Prove it with real data

Prove your policies are working with auditable data showing what's executed, what's blocked, and how your site is protected.

Setup

Live in minutes. No changes to your infrastructure.

Report URI works at the browser layer, so you don't need to route traffic, deploy agents, or modify your application. You get immediate visibility into what's happening — without adding complexity.

Add one response header to your site

Start seeing what's actually executing in your users' browsers right away, without waiting on implementation cycles or additional tooling.

No agents, SDKs, or code changes

Nothing to install or maintain. Get full visibility without adding complexity or introducing risk to your existing environment.

No impact on performance or availability

Your site continues to load and function normally, so you can gain visibility without slowing down your user experience.

Immediate value from day one

See scripts, violations, and changes as they happen so you can start reducing unknown risk immediately.

Get started in minutes — no changes to your infrastructure required.

Why Report URI

Built for what actually runs in the browser

Most security tools lose visibility after your site loads. This is where third-party code can change, introduce risk, and go unnoticed. Report URI works at the point of execution — so you can see what's actually happening, enforce what's allowed, and act with confidence.

01 — Visibility

See what other tools miss

Traditional tools monitor your servers, scan your code, or track known scripts — but not what actually executes after the page loads.

Report URI gives you real visibility into what's running in the browser, including third-party scripts, dependencies, and changes as they happen.

Other tools: rely on server-side scanning, static analysis, and script inventories, which don't show what actually runs in the browser.

Report URI: shows every script executing in real time, including third-party code and unexpected changes.

02 — Enforcement

Enforce what's allowed, not just detect issues

Detection alone doesn't prevent risk. If a script behaves unexpectedly, most tools can only alert you after the fact.

Report URI lets you define what's allowed and enforce it at runtime, so only approved scripts execute — and everything else is blocked or reported.

Detection-only tools: alert you after something has already run.

Report URI: enforces what's allowed at runtime, blocking unauthorized scripts before they execute.

03 — Architecture

Built for the browser layer, not retrofitted

Most tools treat client-side security as an add-on. Report URI is built specifically for how code runs in the browser.

It uses browser-native standards like Content Security Policy (CSP), requires no proxies or injected code, and works without impacting performance or availability.

Other tools: treat client-side security as an add-on or extension.

Report URI: is built for the browser layer, using native standards like CSP without proxies or injected code.

04 — Integration

Works alongside your existing stack

You don't need to replace your current tools. Report URI fills the gap they leave behind in the browser.

It complements WAFs, monitoring tools, and existing controls by giving you visibility and enforcement at runtime — where those tools don't operate.

Other tools: position themselves as replacements, requiring you to consolidate or rip out existing controls.

Report URI: fills the browser-layer gap your WAFs and monitoring tools can't reach, without replacing them.

Compliance

Meet PCI DSS client-side requirements — and prove it

Compliance standards like PCI DSS require visibility and control over what runs in your users' browsers. Report URI gives you the data to prove what's executed and how it's controlled.

Client-side security is now in scope

PCI DSS 4.0 requires you to manage and monitor scripts executing in the browser.

Know what's running — and control it

See every script and enforce what's allowed at runtime.

Generate auditable evidence automatically

Prove compliance with continuous, real-time data — no manual inventories at audit time.

FAQ

Client-side security, answered

What is Report URI?
Report URI is a client-side security platform that gives you visibility into the code executing on your website, lets you enforce what's allowed, and provides auditable data to prove it.
Do I need a credit card to start the free trial?
Yes, a credit card is required to start your trial. You'll get full access to all features for 30 days, so you can evaluate everything before committing. Cancel before day 30 and pay nothing.
What's included in the free trial?
All trials include full platform access. You can see what's running in your users' browsers, define and enforce policies, and explore reporting and compliance features from day one.
How long does it take to get set up?
Most teams are up and running in minutes. You only need to add a response header to your site to start seeing what's executing in the browser.
Will this impact my site's performance?
No. Report URI doesn't proxy traffic or inject code, so there's no added latency or impact on availability. Your site continues to work normally, even if Report URI is ever unavailable.
How is this different from a WAF or monitoring tool?
Most tools focus on your servers or known scripts. Report URI shows what actually executes in your users' browsers and lets you control what's allowed at runtime — the gap WAFs and monitoring tools can't reach.
Does this help with PCI DSS compliance?
Yes. Report URI helps you meet PCI DSS requirements for managing and monitoring scripts in the browser by giving you visibility, control, and auditable data. PCI DSS 6.4.3 specifically requires this — Report URI is built for it.
Do I need to change my infrastructure or deploy new code?
No. Report URI works at the browser layer using existing standards, so you don't need to modify your infrastructure or deploy additional code.
