How Microsoft’s Edge Anti‑Phishing Tech Boosts Chrome’s Security

Microsoft has introduced a Chrome extension named Windows Defender Browser Protection , which brings the built‑in Edge anti‑phishing technology to Google Chrome. When a user attempts to visit a suspicious link, the extension displays a vivid red warning page similar to Chrome’s native safe‑browsing alerts, but powered by Microsoft’s malicious‑link database, also known as the SmartScreen API.

Chrome users can now benefit from both Google’s Safe Browsing API and Microsoft’s SmartScreen API for detecting deceptive and malware‑hosting sites. Although the SmartScreen API is less well‑known than Google’s, its operation is comparable and may even be superior.

According to NSS Labs benchmark results from last year, Edge, which uses the SmartScreen API, captured 99% of all phishing URLs, whereas Chrome detected only 87% of the malicious links visited by users.
