CYBERSECURITY

Email Security — Because 90% of Attacks Start in Your Inbox

Phishing emails are the #1 entry point for ransomware, business email compromise, credential theft, and data breaches. If your email security is just the default Microsoft 365 spam filter, you're exposed. Brivy IT hardens your email with layered protection.

Modern phishing is genuinely hard to detect. AI-generated emails impersonate your CEO’s writing style. Domains with one swapped character send invoices that look exactly right. Links redirect to credential harvesting pages seconds after delivery.

Default Microsoft 365 protection catches ~95% of spam and known malware. The 5% that gets through contains the targeted phishing and BEC attempts that cause real damage.

Advanced Anti-Phishing

AI-powered detection analyzing sender behavior, content, URLs, and attachments — catching targeted attacks default filtering misses.

DMARC / DKIM / SPF

DNS authentication preventing attackers from spoofing your domain. Protects your brand and your contacts.

Microsoft 365 Hardening

Conditional access, MFA enforcement, mail flow rules, admin role cleanup, and security configuration review.

Email Encryption

Automatic encryption for sensitive data — HIPAA-compliant email and secure message portals for external recipients.

Forwarding Rule Auditing

Detection and alerting on inbox forwarding rules — the first thing attackers create after compromise, the last thing businesses check.

Attachment & URL Sandboxing

Suspicious attachments and URLs detonated in sandbox before delivery — catching zero-day malware and delayed-redirect phishing.

FROM THE FIELD

A real estate brokerage almost lost $340,000 in a wire fraud attack. An attacker compromised an agent’s email via phishing, created a forwarding rule, and waited. When a closing was scheduled, they sent modified wiring instructions from a near-identical domain. The buyer’s bank caught it. After remediation, we implemented advanced anti-phishing, DMARC enforcement, conditional access, forwarding rule alerts, and MFA. The attack would now fail at four different layers.

Why Default Email Security Isn't Enough

DMARC adoption is still low. Without DMARC, DKIM, and SPF records, attackers can send emails appearing to come from your domain — to your clients, vendors, and employees.

Compromised accounts are silent. BEC attacks sit quietly in compromised accounts, reading emails and waiting for the right moment. Without forwarding rule auditing and impossible travel alerts, these go undetected for months.

GREAT FIT IF YOU…
  • Business runs on Microsoft 365 and email is critical
  • Had phishing emails reach employees
  • Handle sensitive data via email (financial, medical, legal)
  • Haven't configured DMARC/DKIM/SPF
  • Concerned about BEC and wire fraud
NOT THE BEST FIT IF YOU…
  • Already using a dedicated email security gateway you're satisfied with
  • Email isn't a critical business tool

Frequently Asked Questions

What are DMARC, DKIM, SPF?
DNS records verifying email legitimacy. SPF: authorized sending servers. DKIM: cryptographic signature. DMARC: enforcement policy. Together they prevent domain spoofing.
Will this slow email delivery?
No. Milliseconds of processing latency. Legitimate email flows normally.
Can you fix a compromised email account?
Yes. Password reset, session revocation, forwarding rule removal, investigation, and protection implementation.
Do we need this if we have MFA?
Yes. MFA prevents unauthorized login but doesn't protect against phishing links, malware attachments, or wire transfer social engineering.
Deployment timeline?
Most configurations: 1–2 weeks. DMARC requires 2–4 week monitoring period before enforcement.
