Expert Curated
Email remains the #1 attack vector for Indian businesses — 91% of cyberattacks start with a phishing email. Business Email Compromise (BEC) has cost Indian companies hundreds of crores. Native email security in Gmail and Microsoft 365 is not enough. Dedicated email security adds critical layers of protection.

AI-based sender analysis catches spoofed emails even when they bypass standard filters. National IT Service is an authorised Trend Micro partner for Indian deployments.

Microsoft 365 includes Exchange Online Protection (EOP) which blocks known spam and malware. However, it misses targeted spear-phishing, BEC, and zero-day malware attachments that attackers use against Indian businesses. Adding Microsoft Defender for Office 365 Plan 1 or a third-party tool like Trend Micro significantly reduces the risk.
BEC is when attackers impersonate your CEO, CFO, or vendor to trick employees into transferring money or changing bank details. Indian businesses lose thousands of crores to BEC annually. BEC emails often contain no malware — they bypass antivirus — but AI-based email security tools detect the social engineering patterns and block them.
