Business Email Compromise Protection for Every Inbox

Email is the primary attack surface. Phishing, business email compromise, malicious attachments, and domain spoofing all arrive through the inbox. SADOS blocks threats before they reach users and authenticates outbound messages.

Block Before Delivery

Advanced filters catch malicious attachments, links, and social engineering before reaching mailboxes.

Authenticate Your Domain

SPF, DKIM, and DMARC prove your emails are real and prevent domain spoofing.

Human Oversight

Our team monitors email threat trends and adjusts filters as attack patterns evolve.

How It Works

How Email Security Works

Inbound filtering scans every message for malicious attachments, suspicious URLs, and impersonation indicators before anything reaches your users. Outbound authentication through DMARC, SPF, and DKIM prevents attackers from spoofing your domain to target your clients and partners. Together they create coordinated business email compromise defense.

The Email Security Implementation Process

We assess your current email configuration, identify gaps in filtering and authentication, and implement layered business email compromise protection that integrates with your managed cybersecurity services. Deployment takes one to two business days with zero downtime and no changes to how your team sends or receives email.

What Email Security Services Include

Inbound Threat Filtering

Inbound filtering scans every message for malicious attachments, weaponized links, and social engineering patterns before delivery. Machine learning models evaluate sender reputation, message structure, and payload behavior to catch threats that signature-based scanning misses entirely.

Phishing Defense

Outbound scanning prevents sensitive data from leaving your organization via email. DLP policies flag messages containing credit card numbers, social security numbers, or documents matching confidentiality patterns before they reach external recipients.

SPF/DKIM/DMARC Enforcement

Executive impersonation protection uses display name analysis, domain similarity detection, and behavioral baselines to identify emails pretending to come from your CEO, CFO, or other leaders. These targeted attacks bypass standard spam filters because they contain no malicious payload.

BEC Protection

Business email compromise indicators are flagged on messages mimicking executives, vendors, or partners. Display name spoofing, domain lookalikes, and reply-to manipulation are caught before employees act on fraudulent instructions.

Managed Monitoring

Our team monitors email threat trends targeting your organization and adjusts filters as attack patterns evolve. Monthly reports summarize blocked threats, quarantined messages, and emerging risks specific to your industry.

Common Questions

FAQ

No single layer stops all phishing, which is why our approach to business email compromise protection uses multiple reinforcing defenses. Email security combines pre-delivery filtering, attachment sandboxing, URL rewriting, impersonation detection, and domain authentication to catch threats before they reach inboxes. Social engineering attacks that bypass technical filters are addressed through security awareness training targeting the tactics employees encounter most.
No. Our email security filtering adds negligible processing time to message delivery, typically milliseconds that users cannot perceive in normal workflow. The filtering layer sits in front of your mail platform and scans messages before they reach user inboxes. Deployment takes one to two business days with zero downtime, no MX record disruption during transition, and no changes to how your team sends or receives email.
Yes. We configure business email compromise protection for both Microsoft 365 and Google Workspace environments with platform-specific settings optimized for each architecture. Email security integrates with your existing DMARC, SPF, and DKIM authentication and DNS filtering to create layered defense catching threats across multiple attack surfaces simultaneously.
If a phishing message reaches an inbox and a user interacts with it, our team investigates the scope of exposure, removes the malicious message from all affected mailboxes across your organization, and notifies affected users with clear guidance on next steps. If credentials were entered or attachments were opened, incident response procedures activate immediately. Containment and remediation for business email compromise incidents typically complete within hours.
Email security works alongside DNS filtering, EDR endpoint protection, and MFA as mutually reinforcing layers providing comprehensive business email compromise protection. DNS filtering blocks malicious URLs that bypass email filters. EDR catches malware arriving through any vector. MFA prevents stolen credentials from resulting in account compromise even when initial phishing attempts succeed.
Yes. Email security filtering applies to every mailbox type in your Microsoft 365 or Google Workspace environment without exception. Shared mailboxes, distribution groups, resource mailboxes, and individual user accounts all receive identical inbound filtering, impersonation detection, and attachment scanning as part of our business email compromise protection. Protection activates automatically as new mailboxes are created in your tenant.
