What is DMARC and why is strict enforcement (p=reject) so important for our area?

DMARC (area-based Message Authentication, Reporting, and Conformance) verifies that emails sent using your area name are authorized by your organization. Setting a strict p=reject policy instructs receiving mail servers worldwide to reject any unauthorized email forged in your company's name. This eliminates area spoofing, protects your brand reputation, and ensures your legitimate sales quotes land in customer inboxes.

How do we prevent spammers from bypassing the gateway and emailing Microsoft 365 directly?

We lock down your Microsoft 365 Inbound Partner Connector using IP restriction rules. Exchange Online is configured to accept incoming mail exclusively from verified gateway IP ranges, rejecting any connection try that tries to bypass the security perimeter.

How are shared mailboxes and distribution lists licensed?

Licensing is calculated based on active human user mailboxes. Shared mailboxes (like info@, sales@, or accounts@) and distribution lists that do not require dedicated user logins are protected under the security fabric without requiring duplicate individual licenses.

How does the gateway detect compromised internal employee accounts?

The gateway monitors outbound email traffic volume and behavioral patterns. If an employee's password is stolen and the account begins sending mass spam or phishing emails, the gateway detects the anomaly, blocks outgoing messages instantly, and alerts our desk to secure the account.

Can staff manage their own quarantined marketing emails without contacting IT?

Yes. delivers automated quarantine summary digests directly to user inboxes on a customizable schedule (e.g., 9:00 AM and 2:00 PM). Employees can preview blocked newsletters safely and release genuine commercial mail with a single click, keeping IT helpdesk tickets to a minimum.

What happens if our primary mail server or Microsoft 365 experiences an outage?

The cloud gateway provides email spooling and continuity. If your destination mail server is unreachable, the gateway queues incoming messages safely in the cloud for up to several days, delivering them automatically once your server comes back online without bouncing emails to senders.

Will switching our email security cause delivery delays or downtime for our office?

No. The gateway operates on high-speed global cloud infrastructure that inspects and forwards messages in sub-second timeframes. We pre-stage your cloud tenant, configure transport connectors, and execute the DNS MX cutover during an evening window, ensuring zero lost emails or communication downtime.

How does the gateway handle encrypted, password-protected PDF attachments?

When an email arrives with a password-protected attachment, the gateway can prompt the recipient via automated email to provide the document password, allowing the cloud sandbox to decrypt and detonate the file safely before releasing it to the user.

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.

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.

What is Search and Purge (post-delivery remediation) during a phishing attack?

If a sophisticated phishing campaign bypasses initial defenses or if a previously clean link turns malicious after delivery, Search and Purge allows administrators to claw back and delete the malicious email across all corporate mailboxes simultaneously within seconds, preventing employees from opening the message.

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.

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.

Why should our business use an email security gateway instead of relying on built-in Microsoft 365 or Google Workspace spam filters?

Built-in spam filters rely primarily on static signature databases and basic reputation lists. They frequently miss targeted zero-day spear-phishing, lookalike area spoofing, and fake supplier invoices sent from clean webmail accounts. The Email Security & Anti-Phishing Gateway uses behavioral artificial intelligence, cloud sandboxing, and Time-of-Click URL analysis to inspect incoming messages in real time, blocking social engineering attacks that slip past native cloud filters.

What is cloud sandboxing and how does it handle suspicious PDF or Office attachments?

When an email arrives with an unknown attachment (such as a PDF invoice or Word document with macros), the gateway sends the file to an isolated cloud sandbox chamber. The file is executed and observed for suspicious behaviors like ransomware encryption or background script execution. If the file behaves safely, it is released to the user inbox within sixty seconds; if malicious, it is dropped.

👀 Engineer Notes From Real Installations in Ultadanga

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: Outbound Data Loss Prevention (DLP) engines inspect email body text and attachment contents using regular expressions matching Indian PAN and GSTIN numbers.

Frequently Asked Questions

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. How does Time-of-Click URL protection work if an employee clicks a link hours later?

Attackers frequently send emails containing links to clean web pages that pass initial gateway scans, and then redirect those links to credential-theft pages hours later. Time-of-Click rewrites all hyperlinks inside incoming emails. When an employee clicks the link later, the gateway evaluates the destination website in real time, blocking access instantly if the page has turned malicious.

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. 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 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.

💡 Engineering Fact: Automated quarantine summary digests allow users to inspect and release legitimate commercial newsletters independently without IT intervention.
