Email Security Solutions
for Indian Businesses

Email security refers to the tools, policies and processes that protect business email from threats — phishing, malware, BEC (business email compromise), ransomware and data exfiltration. Indian businesses need dedicated email security because built-in filters in Google Workspace and Microsoft 365 use signature-based detection tuned for mass campaigns, not the targeted, AI-generated attacks that dominate today's threat landscape. BEC attacks alone cost Indian businesses thousands of crores annually — and most begin with a single email.

For mass spam and known malware — yes. For targeted threats — no. Google and Microsoft's built-in filters do not include: advanced BEC/impersonation detection using AI, cloud sandboxing for zero-day attachments, time-of-click URL rewriting, email continuity during platform outages, or 99-year compliance archiving. A dedicated email security gateway adds all these layers while working alongside your existing platform.

BEC is when an attacker impersonates a CEO, CFO, vendor or bank to trick an employee into transferring money, sharing login credentials, or revealing sensitive information. The email looks legitimate — it may use the executive's real display name, a lookalike domain, or a compromised internal account. BEC is the #1 email threat globally; India is among the top 5 targeted countries by volume. Unlike malware, BEC carries no malicious files or links — standard antivirus cannot detect it. Only AI-powered impersonation detection catches it.

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that tells receiving mail servers what to do with emails that fail SPF or DKIM checks — quarantine them or reject them outright. Without DMARC enforcement (p=reject), anyone can send email that appears to come from your domain. Google and Yahoo mandated DMARC for bulk senders in 2024. Most Indian businesses still run p=none (monitoring only). Cloudfy sets up SPF, DKIM and DMARC as part of every email security deployment — and Mimecast includes a DMARC Analyser to help you reach p=reject safely.

An email gateway sits in front of your existing email platform by redirecting your domain's MX records to the gateway server. All inbound email flows through the gateway first — it scans for threats using AI, sandboxing, threat intelligence and URL rewriting — then delivers clean email to your Google Workspace or Microsoft 365 inbox. Outbound mail can also be routed through the gateway for DLP and authentication. The alternative is API-native integration (like Barracuda's) which uses the mail platform's API to scan after delivery, with no MX change required.

For small businesses (under 50 users) using Google Workspace: Sophos Email Security Advanced is the most cost-effective option — AI BEC detection, sandboxing and time-of-click URL protection at a per-user price that scales with your team. For Microsoft 365 users: if you're already on Business Premium, activating Microsoft Defender for Office 365 Plan 1 (included in your licence) is the first step — Cloudfy configures it at no extra licensing cost. For businesses needing archiving, Mimecast's Core Email Security tier is the entry point.

For MX gateway deployments (Sophos, Mimecast, Proofpoint): MX record change + policy configuration + SPF/DKIM alignment takes 2–4 hours for up to 100 users. DNS propagation adds up to 48 hours for global coverage — during which the previous mail path continues. No email downtime. For API-native deployments (Barracuda): connected to M365 via Graph API in under 2 hours, no MX change required. Microsoft Defender activation: 1–2 hours for initial configuration and policy tuning.
