Defense pipeline

Three layers. One verdict.

No black boxes — each layer contributes a signal before QubitShield reaches a final safety classification.

01

URLHaus intelligence

Every destination is checked against a live feed of known malware, phishing, and command-and-control URLs.

02

Multi-modal AI

Vision and semantic models inspect page content and intent — catching threats that signature lists miss.

03

Behavioral signals

Redirect chains, geo rules, and password gates are analyzed together for a complete safety picture.

How it works

Inspect any link in three steps

1

Paste a link

Drop any short link or full URL. We do not store what you paste.

2

Parallel scan

URLHaus, AI heuristics, and behavior checks run at the same time.

3

Clear verdict

See geo rules, password gates, and a safe / unsafe result before you click.

Auto-neutralizeZero-day aware

Threats get blocked before your audience sees them

When QubitShield flags a destination, the link is neutralized and visitors see a high-visibility warning — protecting your users and your brand reputation.

What is QubitShield?

QubitShield is QubitLink’s AI-powered security layer. It checks the destination of a link for phishing, malware, and deceptive pages, so you can share short links knowing your audience is protected.

What does QubitShield actually scan?

It analyzes both the destination URL and the full redirect chain. Many threats hide behind several hops, so looking at the whole path helps catch unsafe pages that a simple check of the final URL could miss.

What happens when a link is flagged as unsafe?

Unsafe destinations can be blocked before your audience lands on them. This protects your visitors and your brand’s reputation, since your short link won’t send people to a harmful page.

Do I need to be a QubitLink customer to check a link?

No. The Public Link Checker is free and requires no account. Paste a link and you’ll get a QubitShield-oriented safety report.

Can I check a link before sharing it in an email, chat, or bio?

Yes. The Public Link Checker expands short links and inspects redirects, which makes it useful for vetting a campaign link before it goes into an email, a chat, or a social bio.

Does QubitShield work with my own branded links?

Yes. QubitShield is built into the QubitLink workspace alongside branded short links, click analytics, and bio landing pages, so your links can be scanned whichever domain they use. Custom domains are available on paid plans; see pricing at https://qubitlink.co/pricing.

Can I use QubitShield outside the website?

Yes. QubitLink offers apps for browsing and managing links on the go, including a Chrome extension, an Android app, and an iOS app. See all options on the Apps page at https://qubitlink.co/apps.
