Time-of-Click Protection – with the URL Safeguard in NoSpamProxy

One of the most dangerous tactics used in cyber attacks is to send seemingly harmless links in emails that only lead to phishing sites or malware after they have been received. Traditional spam filters and virus scanners quickly reach their limits here, as they only check emails once when they are received. But what happens if the link later becomes dangerous? This is exactly where Time-of-Click Protection (ToC Protection) comes in. In this article, we show you how Time-of-Click Protection works, why it is indispensable for companies, and how it is integrated into URL Safeguard in NoSpamProxy.

NoSpamProxy includes a wide range of ATP functions as standard, which do not require additional licensing.
