Time-of-click protection is the security check performed when a user clicks a link rather than only when the message was first delivered. It matters because malicious infrastructure and landing pages can change after delivery, making a one-time pre-delivery judgment incomplete.
What is Time-of-Click Protection?
This control often works with link rewriting to reassess a URL’s risk at the moment of user interaction. It can block newly risky sites, warn users, or gather telemetry on attempted phishing engagement.
What Time-of-Click Protection Commonly Supports
Common uses include phishing defense, URL reputation enforcement, evolving threat response, and click-behavior monitoring.
Time-of-Click Protection vs. Delivery-Time Link Check Only
Time-of-click protection evaluates links at the moment they are used. Delivery-time-only checks rely on older information and may miss later changes.
Frequently Asked Questions
Why is click-time analysis valuable?
Because attackers often change destinations after a message gets through initial scanning.
Does it prevent every malicious click?
No. It improves defense, but determined attackers and rapid infrastructure changes can still create gaps.
