Festival rush weeks and financial year-end closing around Kolkata are when fraudulent bank mandate change requests peak. Scammers inject themselves into existing vendor email threads using stolen credentials, altering bank account numbers on PDF vouchers just as payment is scheduled. Email Security & Anti-Phishing Gateway inspects internal mailbox communications, detects anomalous reply-to addresses, and identifies hijacked vendor mailboxes using behavioral anomaly detection. We set up each mail gateway with custom financial warning banners, ensuring your finance team never transfers funds to a fraudster's account.
🧭 Sizing, Licensing and Ordering Email Security & Anti-Phishing Gateway at multi-branch offices
The external statutory compliance auditor asked for proof of email data loss prevention (DLP), executive impersonation controls, and historical quarantine logs, and nobody could produce a report from standard webmail. A Email Security & Anti-Phishing Gateway enforces automated DLP rules that detect outgoing PAN numbers, GSTIN details, bank accounts, or source code, blocking unauthorized leaks or encrypting sensitive outgoing messages automatically. Reports export directly from the central cloud console, turning an audit scramble into a simple demonstration.
Running email security without centralized threat remediation means that when a sophisticated phishing email reaches twenty employees, an IT administrator must manually log into each mailbox to delete the message. An enterprise Email Security & Anti-Phishing Gateway features automated post-delivery remediation (Search and Purge). The moment a threat is identified in a single mailbox, the system searches all corporate inboxes and claws back the malicious email across the entire company within seconds, preventing other staff from clicking.
🔑 Why Businesses Pick Email Security & Anti-Phishing Gateway when budgets are tight
Very few companies keep a fixed employee headcount over time. Start with thirty mailboxes today, and the same cloud architecture scales easily to protect additional domains, shared mailboxes, and hundreds of users simply by adjusting license quantities. We design each email security deployment near Shyamnagar with flexible scaling so your communications protection grows alongside your business.
Ask any business owner whose accounts department transferred funds against a fake invoice what caused the failure. The answer is almost always the same: the email came from a lookalike area name that slipped past basic spam filters and fooled an employee who was in a hurry. The Email Security & Anti-Phishing Gateway uses behavioral artificial intelligence to identify executive impersonation, area spoofing, and writing anomalies before the message reaches a desk. Businesses around Shyamnagar invest in genuine email security once and eliminate catastrophic invoice fraud permanently.
A 60-user export manufacturing headquarters near Shyamnagar narrowly avoided a thirty-five lakh rupee fraud when a scammer sent an email from an overseas supplier's hijacked account requesting urgent payment to a new bank account. We deployed Email Security & Anti-Phishing Gateway with advanced BEC detection and financial keyword inspection. The gateway flagged the bank detail change anomaly and isolated the message into quarantine. Our engineering desk confirmed the supplier's account had been compromised overseas, completely preventing the fraudulent transfer.

🧮 What the Numbers Mean for Your Office for larger offices
Mail flow architecture is engineered for zero on-premise hardware overhead. The gateway connects directly to your area via public DNS MX record routing or secure cloud API connectors (supporting Microsoft 365 and Google Workspace). Inbound messages are inspected in the cloud before reaching your mail server, while outbound messages are signed with cryptographic DKIM keys and scanned for sensitive data leaks.
The multi-layered anti-phishing engine combines natural language processing, sender writing pattern analysis, and area age verification to defeat Business Email Compromise (BEC). Messages attempting to impersonate directors, partners, or approved suppliers using lookalike area names or forged display names are intercepted and quarantined automatically.

✉️ SUPPORT DESK
Coordinate custom hardware configurations, AMC maintenance contracts, and site engineering visits directly with authorized integration desks.
Q. Can we configure visual warning banners on external emails?
Yes. We configure customizable HTML warning banners injected into the top of external messages (e.g., 'CAUTION: External Sender'). This provides an immediate visual checkpoint for employees before clicking links or processing payment instructions.
Q. What maintenance is required to keep our email security operating reliably?
Routine maintenance includes reviewing monthly DMARC aggregate XML reports, updating VIP impersonation tables, inspecting quarantine false-positive rates, verifying SPF lookup limits, and tuning DLP rules during scheduled maintenance windows.
Q. Can the gateway protect multiple subsidiary domains under one company account?
Yes. Multi-tenant architecture allows managing multiple corporate domains, subdomains, and subsidiary brands from a single web console, applying standardized security rules while maintaining area-specific routing.
Q. What is Business Email Compromise (BEC) and how does the gateway stop fake invoice fraud?
Business Email Compromise occurs when an attacker impersonates a company director, partner, or trusted supplier (often using a lookalike area name with one altered letter) to trick an employee into transferring funds or changing bank account details. Email Security analyzes sender writing styles, area registration ages, and display names, automatically quarantining impersonation attempts before they reach accounts staff.
Q. Who owns the email security tenant logins, DMARC keys, and policy documentation?
You do. At project sign-off, we hand over a complete documentation package containing your cloud tenant URLs, administrative credentials, 2048-bit DKIM selector keys, DMARC reporting mailbox logins, and transport connector maps. Your company retains full ownership.
💡 Engineering Fact: Exchange Online Inbound Connectors locked to gateway IP ranges prevent attackers from bypassing email security by routing mail directly to tenant addresses.
