Phishing Detection & Email Security Monitoring is a continuous security service designed to identify, analyze, and respond to email-based threats such as phishing, credential harvesting, malware delivery, spoofing, and business email compromise (BEC). The service monitors email traffic, security logs, authentication events, and user-reported messages to detect malicious patterns, suspicious sender behavior, abnormal email flows, and social engineering techniques. Advanced analysis is used to identify threats that bypass traditional email filtering, including zero-day phishing campaigns and targeted attacks. Suspicious emails are analyzed for malicious links, attachments, impersonation indicators, domain spoofing, and anomalous communication behavior. When a threat is confirmed, response actions may include alerting, containment guidance, IOC blocking, user notification, and integration with incident response workflows. This service aligns with CERT-In advisories, email security best practices, and incident response standards, ensuring timely detection, minimal user impact, and audit-ready reporting.
