LinkQuarantine – safe preview for untrusted links

Preview unknown links in a disposable sandbox before opening them

Problem
Users constantly need to open untrusted links from chat, email, or social media but fear phishing, tracking, or malicious scripts; opening directly is risky, and manually moving them to an isolated environment is too much friction.
Solution
A lightweight desktop/browser extension intercepts clicks and opens the link in a disposable Linux VM or isolated browser, showing only a screenshot or sanitized content; the environment self-destructs on close.
Users
Security-conscious individuals, journalists, researchers, and support/ops staff who must open user links
MVP
Send links to an isolated browser via right-click or hotkey; one-shot session destroyed on close; render static screenshots or sanitized HTML; blacklist/whitelist support; runs locally with no cloud account
Revenue
One-time purchase or annual subscription; team plan with centralized policies and audit logs; distribution partnerships with security vendors
Why now
Browser and container tech is mature enough to spin up disposable local VMs cheaply; phishing and supply-chain attacks are rising, yet ordinary users still lack an easy isolation preview tool
