Protecting your code, or watching everyone else's

Code protection makes your own JavaScript hard to read, tamper with or lift. Client-side security governs what third-party code is allowed to do on your pages, and records what it did. These solve genuinely different problems, and plenty of organisations want both.

Code protection

Jscrambler

Hardens the JavaScript you wrote, with monitoring layered alongside it.

Client-side security platform

Report URI

Governs what every script on the page may do, and records what it did — most of which you did not write.

Where Each One Sits

One acts on your code. The other observes all of it.

Code protection operates at build time on the JavaScript you control, which is exactly the code you already have the most visibility into. The scripts that cause client-side incidents are usually the ones you did not write and cannot rebuild — a tag manager's payload, a vendor's widget, a dependency of a dependency.

Code protection

Your source Hardened at build Browser

Applies to code you own and can rebuild. Third-party scripts arrive on the page by another route entirely.

Client-side security platform

Every script Browser Report URI

Governs and records whatever executed, regardless of who wrote it or how it got there, including scripts loaded by other scripts.

Head to Head

What follows from each architecture

These are complementary more often than they are alternatives. The comparison is about which problem you are solving today.

Consideration	Code protection	Report URI
Primary subject	The JavaScript you wrote	Every script that executes, most of which you did not write
Where it acts	Build pipeline, before deployment	After the fact, on what the browser actually did
Third-party scripts	Cannot be rebuilt, so cannot be hardened	Inventoried, fingerprinted, and archived when they run
Build coupling	Part of your release process	None — a response header, independent of releases
Intellectual property	Obfuscation makes your logic hard to lift	Not addressed; a different problem
Script payloads	Yours, by definition	Anyone's, fetched and hash-verified against the browser's fingerprint
Report types	Script and page integrity	Fourteen, spanning scripts, connectivity, isolation and identity
Pricing	By quotation	Published on the site

Why It Matters Here

The code that hurts you is rarely the code you shipped

Card skimming, cryptojacking and data exfiltration overwhelmingly arrive through a third party rather than through your own bundle. That is the code you cannot rebuild, and therefore the code that needs observing.

Fourth-Party Reach

Including the scripts your vendors load

A tag manager loads a tag, which loads something else. Those later dependencies never appear in any repository you own, never pass a review, and execute with the same privileges as everything else on the page. Because reporting comes from the browser, they are visible on the same footing as your own code.

Integrity

Assuring integrity without rebuilding anything

Subresource Integrity lets the browser refuse a script whose contents have changed, and Integrity Policy reports or enforces that every eligible script carries it. CSP Integrity fingerprints what actually executed and names the library and version. None of that requires access to anybody's source, which is what makes it applicable to third-party code.
