Vendor & Platform Overview

Guardio is a modern cybersecurity innovator focusing on securing the web browser—the primary operating system of the modern internet user. Protecting millions of individuals and small businesses, Guardio blocks malicious browser extensions, deceptive push notification hijacks, real-time phishing traps, and data leaks directly at the browser layer where traditional antiviruses struggle to maintain visibility.

Architecture & Detection Telemetry

Guardio operates natively within Chromium-based browsers, Firefox, and Safari via an optimized web extension utilizing the Chrome Extension Manifest API. It analyzes DOM modifications, script injection attempts, external network calls, and notification subscriptions in real time. Backed by proprietary machine learning models, Guardio evaluates web destinations dynamically rather than relying solely on lagging URL blocklists.

Frequently Asked Questions

Why is browser-level security necessary if I already have antivirus software?

Modern attacks predominantly happen inside the browser (phishing, malicious extensions, rogue push notifications, and cookie harvesting) without downloading executable files to disk. Traditional antivirus software often cannot inspect inside encrypted browser sessions, creating a blind spot that Guardio eliminates.

How does Guardio stop deceptive push notification spam?

Guardio scans installed browser permissions and service workers, automatically revoking permissions from deceptive sites that trick users into clicking 'Allow' and bombarding them with fake virus warnings and adware pop-ups.

Does Guardio slow down web browsing speed?

No. Guardio's extension is designed for near-zero latency, evaluating page elements asynchronously without backhauling web traffic to external proxy servers.
