Phishing prevention

Every link followed. Every page read.

Q: Does detonation happen before or after delivery?

After. Aegis reads mail through the API, reaches a verdict in 1.9 seconds at the median, and removes a convicted message within seconds.

Q: Do you follow every redirect?

Yes, hop by hop in an isolated browser, and the chain is recorded in the verdict.

Q: Can a CAPTCHA-gated page defeat the sandbox?

Gates are hard for any automated system. Aegis treats the gate itself as evidence and never scores a hidden page clean.

Q: How are QR codes handled?

Decoded to a URL and detonated like any other link.

Aegis opens every link, file and QR code in a sandbox, follows it to the end, and judges what it finds there.

The problem

The first hop looks clean. The payload is further in.

Attackers hide the page behind redirects, human checks and QR codes, often on infrastructure you trust. Reputation only sees the start.

How it works

How Aegis follows a phishing link

What it catches

Four ways the payload hides

Redirect chains

Trusted hops in front of the harvest page.

Gates and delays

A CAPTCHA or a clean first version that scanners never get past.

QR codes

The link is a picture, scanned on a phone.

HTML smuggling

A file that builds its payload inside the browser.
