Email Is Your Biggest Attack Surface.

Microsoft 365 and Google Workspace include basic spam filtering โ€” but basic isn't enough against modern threats. Today's phishing emails are sophisticated, highly targeted, and often impersonate your CEO, your bank, or your vendors. Business Email Compromise (BEC) attacks cost U.S. businesses billions annually.

IT Umbrella Group deploys advanced email security that goes beyond spam filtering: AI-powered phishing detection, malicious attachment sandboxing, URL rewriting, impersonation protection, and full SPF/DKIM/DMARC authentication. We also handle the forensic investigation when a suspicious email does get through.

We've investigated real BEC attacks in the RGV. In one case, attackers used a lookalike domain (bigrealtys.com vs bigrealty.com) to intercept a real estate wire transfer. Proper DMARC configuration and email security tools can catch these attacks before anyone clicks.

Everything Your Business Needs

Built for RGV businesses that can't afford downtime or surprises.

๐ŸŽฃ
Anti-Phishing AI
Machine learning models that analyze email content, sender reputation, header anomalies, and link destinations to catch sophisticated phishing that signature-based filters miss.
๐Ÿ’ผ
BEC Protection
Detects executive impersonation, vendor fraud, and invoice manipulation attacks โ€” the high-value attacks that cause the most financial damage to businesses.
๐Ÿ”—
Link Protection
Every URL in every email is rewritten and checked at click-time against real-time threat intelligence. Links that become malicious after delivery are still blocked.
๐Ÿ“Ž
Attachment Sandboxing
Suspicious attachments detonated in an isolated sandbox environment before delivery. Malware hidden in Office documents, PDFs, and ZIPs is caught before it reaches your inbox.
โœ…
SPF/DKIM/DMARC
Email authentication records that prevent attackers from spoofing your domain. We configure and monitor all three โ€” stopping outbound impersonation of your brand.
๐Ÿ“Š
Threat Reporting
Regular reports showing blocked threats, quarantine activity, top targeted users, and trending attack types โ€” so you understand your threat landscape.

Simple Process.
