Email Security — Protecting Indian Businesses from Phishing & BEC

Email security software protects your business by blocking phishing emails, malware attachments, and Business Email Compromise (BEC) scams before they reach your employees' inboxes — preventing the most common type of cyber attack.

Email is the primary attack vector for cybercriminals targeting Indian businesses. Email security encompasses multiple technologies: anti-spam (blocking junk mail), anti-phishing (detecting fake login pages and credential-stealing emails), malware scanning (checking attachments and links for malicious content), and advanced threat protection for Business Email Compromise (BEC) — sophisticated scams where attackers impersonate your CEO or supplier to trick employees into transferring money or sharing sensitive data. Modern email security platforms use AI to detect BEC based on writing style, sender behaviour, and communication patterns.

Anti-Phishing: Detects emails impersonating banks, GST portal, Microsoft, Google, and other trusted entities to steal credentials.
BEC Detection: AI-based detection of Business Email Compromise — catches supplier payment fraud, CEO fraud, and account takeover attempts.
Malware Sandboxing: Opens attachments in a secure virtual environment to detect malware before delivering to the user.
DMARC / DKIM / SPF: Email authentication protocols that prevent email spoofing — making it harder for attackers to send emails appearing to come from your domain.
