Securing communication channels is essential to countering phishing and fraud. Email protocols like SPF, DKIM, and DMARC verify sender authenticity, ensuring emails aren’t tampered with. Anomaly detection systems bolster this by identifying suspicious user behavior, such as logins from unfamiliar devices or unusual locations. Together, these strategies protect both organizations and individuals, keeping their communications private and secure. Investing in secure communication tools helps prevent exploits that could compromise sensitive information.
