Customize web protection

Sometimes you may need to customize web protection settings for certain categories of traffic or certain domains. For example, you may not want to decrypt HTTPS traffic for financial services websites because they contain sensitive financial data. You also may want to skip malware scanning and Zero-day protection analysis for sites that you know are low-risk. You can specify this behavior using exceptions.
