Email remains the number one gateway for cyberattacks. Whether phishing, malware, or targeted manipulation—the threats are constantly evolving. This makes it all the more important for companies to regularly review their email security. Email penetration tests are an effective way to do this. They simulate real attack scenarios and uncover vulnerabilities. This gives organizations a clear assessment of how resilient their communications infrastructure really is – and where urgent improvements are needed.

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.
