Network safety
Reject private, reserved and unresolved network destinations before any active request.
Nova Shield
Analyze a Link Before You Trust It
Check DNS, HTTPS, domain age, and redirect behavior with a clear, privacy-conscious report.
Reports store a redacted version of the submitted URL. Sensitive query parameters are masked, reports are unlisted, and checks run without sending the URL to third-party browser-scanning services.
Do not submit password-reset links, private invitations, signed download URLs, or addresses containing access tokens.
Nova Shield helps identify common technical and reputation risks, but no automated scan can guarantee that a destination is safe.
HTTPS certificate
Validate the certificate hostname, trust chain and remaining lifetime.
Domain age
Read structured registration dates through the authoritative RDAP system.
Redirect chain
Inspect each redirect hop with DNS safety checks and strict limits.
How the Safety Score Works
The score combines explainable technical and reputation signals. DNS resolution and private-network checks prevent unsafe internal requests; HTTPS status, domain age, redirect behavior, quarantine history, and hostname or URL reputation can raise or lower the result. A missing RDAP record means registration data was unavailable, not that a destination is automatically dangerous.
Every redirect hop is resolved and validated separately. Requests use strict protocol, timeout, response-size, and redirect limits to reduce SSRF and resource-exhaustion risk.
Continuous protection
Protection that continues after the first scan
Nova Shield reuses current evidence instead of calling an external provider on every redirect, then refreshes checks when the destination or risk state changes.
At creation
The destination is checked before a protected short link is created.
After an edit
Changing the destination queues a fresh safety decision before normal use continues.
When evidence is stale
Expired results are refreshed automatically while redirects use the latest safe cached decision.
When risk changes
Owners receive a clear status change and visitors receive a warning or block when required.
Redirect normally
Current evidence is cached and reused without delaying every click.
Warn before continuing
Visitors see the destination and risk context before choosing whether to continue.
Stop a dangerous redirect
Critical policy or reputation signals quarantine the link until it is reviewed and rechecked.
Honest boundaries
What this scan does not claim
Nova Shield does not execute a full browser session, submit forms, bypass authentication, or guarantee that page content will remain safe. It reports the technical and reputation evidence available at the time of the check.
