Multitier Security & Policy Control FAQs
Multi-layered security is essential in protecting business email against modern threats because today's attacks often exploit multiple vulnerabilities across different stages of an email’s lifecycle. A defense-in-depth approach ensures comprehensive protection by integrating technologies like malicious URL defense, email authentication protocols (SPF, DKIM, DMARC), and advanced spam and virus detection engines to prevent credential phishing, malware, spoofing, and polymorphic viruses. As attackers increasingly use sophisticated techniques such as social engineering and zero-day exploits, layered defenses can intercept threats before they reach inboxes and block advanced attacks that traditional security systems fail to detect. This approach also provides adaptive measures to identify emerging risks, quarantine malicious messages, protect sensitive data, and reduce the likelihood of account takeovers or fraud, ensuring business email remains secure and operationally resilient.
