JavaScript protection

DataUnlocker Defender is part of a powerful suite of technologies designed to protect your web application from modern threats like ad blockers, privacy extensions, and unauthorized tampering.

At the heart of this protection lies Secure Enclave — a feature that enables secure, invisible delivery of sensitive frontend logic like tracking.

Meet DataUnlocker Defender

Defender is our advanced web app shielding engine. Together with Secure Enclave, it brings a robust layer of protection to your frontend, adding:

🔐 Code obfuscation – Prevents reverse engineering and inspection of your JavaScript.

🚀 Secure frontend delivery – Ensures critical code reaches users, even under blocking conditions.

🛡️ Tampering protection – Guards your frontend against unauthorized modification.

♻️ Continuous blocker defense – On the Business plan, we monitor public filter lists and auto-adapt to bypass new rules.

These technologies work seamlessly in the background, so your app stays fast, reliable, and secure — regardless of your users’ browser extensions or network filters.

Why it matters

Modern privacy tools often interfere with essential JavaScript. This can break functionality, disable analytics, or lead to inconsistent user experiences.

With JavaScript protection, DataUnlocker ensures that your code stays:

• 📦 Hidden from blockers — Delivered from a hardened source, not easily detected or filtered.
• 🧩 Resilient — Obfuscated and served independently of your main assets.
• 🔄 Always protected — With real-time rule monitoring and automated adjustments (Business plan).

How it works

With Secure Enclave, you can upload custom JavaScript code directly into a secure container. This code is served to users via DataUnlocker Defender — bypassing blockers and providing a high-assurance delivery channel.
