A fake email claiming to be from your managing director asking for an urgent RTGS bank transfer rarely carries a detectable virus attachment; it carries clean text sent from a lookalike area name with an extra letter. Basic antivirus scanners wave those messages straight through because there is no malware payload to trigger a signature. Email Security uses advanced natural language processing and sender identity verification to spot business email compromise (BEC) and executive impersonation in real time, tagging or dropping the message before an accounts clerk can act on it. At Microtech Solutions, we deploy this layer alongside strict DMARC enforcement so your company identity cannot be forged.
✅ Email Security & Anti-Phishing Gateway Supply, Setup and Support anywhere in Kolkata
Opening a branch office in another town used to mean setting up local mail relays and trying to coordinate security settings across fragmented accounts. With Cloud Email Security, all corporate domains, subdomains, and user mailboxes are managed through a single web dashboard. Security policies, custom warning banners, and quarantine digest schedules are pushed centrally from our console. If an employee at a branch in Kolkata reports a suspicious email, our engineering desk inspects and quarantines it remotely.
Buying email security per-gigabyte without considering user count means you run into unpredictable overage charges during high-volume communication months. We size the Email Security & Anti-Phishing Gateway with transparent per-mailbox annual licensing: covering all incoming, outgoing, and internal email traffic with unlimited cloud sandboxing and quarantine storage. Tell us your active user count and we will configure an email security foundation built for reliable, predictable operations.
🧠 What Changes in the First Month with a growing team
Business leaders do not want to parse raw mail header logs; they want clear visibility into blocked phishing attempts, impersonation trends, and area reputation health. Management tools create clean visual dashboards that report threat volumes, targeted employee names, and quarantine summaries directly to your inbox. When auditors or insurance assessors request cybersecurity controls, you have verified reports ready to share.
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 Mandirtala with flexible scaling so your communications protection grows alongside your business.

💡 Engineer Notes From Real Installations after years of site visits
Always configure DMARC reporting before enforcing strict rejection. I start clients on p=none for thirty days to monitor DMARC aggregate (RUA) XML reports, identifying legitimate third-party sending services like ERP relays or CRM tools. Once all valid senders are authorized in SPF and DKIM, we switch the policy to p=quarantine and finally p=reject to seal the area.
Basic DNS spam filters (DNSBL) only check sender IP addresses, allowing malicious emails sent from compromised legitimate Microsoft 365 or Gmail accounts to slip through unnoticed. Inspects email content semantics, attachment payloads, and linguistic anomalies regardless of sender IP reputation.
Traditional email gateways only inspect links at the moment the email enters the network, leaving users vulnerable to delayed phishing links that activate hours after delivery. Time-of-Click rewrites and re-evaluates URLs in real time whenever an employee clicks the link.
💡 Engineering Fact: DKIM cryptographic signing uses 2048-bit private keys to attach digital signatures to outgoing email headers, proving message authenticity.
Frequently Asked Questions
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. How does Outbound Data Loss Prevention (DLP) prevent confidential data leaks?
Outbound DLP inspects outgoing emails and attachments for sensitive data patterns like Indian PAN cards, Aadhaar numbers, GSTIN codes, and bank account numbers. If an employee attempts to email unencrypted confidential records, the gateway can block delivery, notify compliance managers, or automatically route the message through an encrypted web portal.
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.
Q. Why should we procure Email Security through Microtech Solutions instead of buying online?
Procuring through Microtech Solutions guarantees your email security is engineered by certified systems professionals. You receive full SPF/DKIM/DMARC alignment, Microsoft 365 connector lockdown, VIP impersonation rule tuning, cloud sandboxing verification, and ongoing local engineering support across Kolkata.
Q. What is Quishing and how does the software detect QR code phishing attacks?
Quishing occurs when attackers embed malicious phishing links inside QR codes attached as images or PDF files to bypass text-based spam filters. Email Security uses computer vision and Optical Character Recognition (OCR) to extract QR codes from attached images, analyzing destination URLs against live threat databases and blocking credential-theft attempts.
💡 Engineering Fact: High-visibility visual warning banners injected into external emails alert employees to exercise caution before clicking links or processing payments.
