A Key Threat Damaging Your Business

Lack of visibility

Your website’s client-side is a security blind spot and this endpoint can easily be targeted by malicious actors.

Client-side chaos

The average website today runs 35 different third-party components. Each of these can be compromised and breach your website without your awareness.

Zero client-side control

These leaks stay active for weeks or even months before being detected, resulting in massive data breaches.

A New Layer to Protect User Data

Full Coverage of Data Exchanged at The Client-Side

Gain full visibility over every network request that happens at the client-side and a real-time summary of all potential data leakage incidents.

Proactive Security Approach

Avoid a breach of compliance with data protection regulations by ensuring that any attempt to leak user data will be blocked at its inception, regardless of the attack vector.

Protection Ingrained in The Source Code

Protect your client-side source code with cutting-edge obfuscation and runtime protection capabilities that prevent the leakage of sensitive data, as recommended by OWASP and NIST.
