However, <\/span><b>Lena Kannappan<\/b><span style=\"font-weight: 400;\">, CISO at Healthcare Triangle Inc., advocates for a move toward <\/span>intent-based email security<span style=\"font-weight: 400;\">. This technological shift analyzes behavioral patterns, communication context, and anomalies to determine the underlying reason a message was sent.<\/span><\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Lena Kannappan highlights that this approach is vital for the detection of <a href=\"https:\/\/threatcop.com\/blog\/zero-day-attack\/\">zero-day attacks<\/a> and sophisticated social engineering. In a healthcare setting, intent-based security is critical for protecting Protected Health Information (PHI) and Electronic Health Records (EHR) from ransomware, which is a significant threat to the industry. By identifying impersonation patterns, this technology prevents disruptions to clinical workflows that could otherwise lead to patient safety issues. While Lena notes that challenges remain in integrating these newer tools with existing SOC environments, she views this as the necessary road map for mid-to-large-scale hospitals.<\/span><\/p>\n\n\n\n\n<!DOCTYPE html>\n<html lang=\"en\">\n\n<head>\n    <meta charset=\"UTF-8\">\n    <meta http-equiv=\"X-UA-Compatible\" content=\"IE=edge\">\n    <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\">\n    <title>Document<\/title>\n<\/head>\n\n<style>\n    .interestedBtn {\n        width: 70% !important;\n        box-sizing: border-box !important;\n        display: inline-block !important;\n        padding: 11px !important;\n        border: 1px !important;\n        border-color: #ddd !important;\n        margin-top: 10px !important;\n        background-color: #fff !important;\n        background-image: none !important;\n        text-shadow: none !important;\n        color: #000 !important;\n        font-size: 14px !important;\n        line-height: 20px !important;\n        border-radius: 5px !important;\n        margin: 0 !important;\n        cursor: pointer !important;\n    }\n\n\n.formSec .formSecTwo{\n    padding-top: 30px !important;\n}\n\n\n    .tnp-email {\n         width: 70% !important;\n    box-sizing: border-box;\n    padding: 8px 10px;\n    display: inline-block;\n    border: 1px solid #ddd;\n     background: #183e8b;\n    color: #fff !important;\n    font-size: 13px;\n    line-height: 20px;\n    border-radius: 2px;\n    padding-right: 30px;\n    margin-bottom: 0px;\n\n    }\n\n    .formSec {\n        float: left !important;\n        width: 55% !important;\n    }\n\n    .mainBox {\n            background: #183e8b;\n        max-width: 600px !important;\n        margin: 0 auto !important;\n        padding: 20px !important;\n        font-family: Arial, Helvetica, sans-serif !important;\n    }\n\n    .boxDiv {\n        display: flex !important;\n    }\n\n    .boxConsult {\n        float: left !important;\n        width: 45% !important;\n    }\n\n    .formSecTwo {\n        text-align: right !important;\n        width: 100% !important;\n    }\n\n    .formHeading {\n        font-family: Arial, Helvetica, sans-serif;\n        margin-top: 0px;\n        font-weight: 700;\n        line-height: 25px;\n        font-size: 18px !important;\n        margin-bottom: 70px;\n       margin-bottom: 70px !important;\n       color: white !important;\n          margin-top: 0px !important;\n    }\n\n    .fieldHeading {\n        margin: 0 !important;\n        font-size: 13px !important;\n        text-align: left !important;\n        margin: 0px 39px 2px 93px !important;\n        font-weight: 500 !important;\n    }\n\n    .image {\n        max-width: 100% !important;\n        height: auto !important;\n    }\n\n     .email-icon {\n            position: absolute;\n            right: 10px;\n            top:18px;\n            transform: translateY(-50%);\n            pointer-events: none;
