Stop the threat before it hits the inbox.
AUCyber configures, tunes and operates Microsoft Defender for Office 365 around your business - phishing, business email compromise (BEC), malware and impersonation, all under managed control.
WHY EMAIL IS STILL #1
Email is still how attackers get in.
Phishing, BEC and supply-chain spoofing are the most common entry points for ransomware, fraud and data theft. Out-of-the-box Microsoft 365 protection blocks the easy stuff - but the dangerous campaigns target your specific business.
Targeted phishing
Spear-phishing tailored to your staff and suppliers slips past generic gateways every day.
Business email compromise
A single hijacked finance mailbox can cost you six figures before anyone notices the wire.
Malicious attachments and links
QR codes, OneDrive links, callback phishing - modern payloads bypass attachment scanning entirely.
Invoice and supplier fraud
Spoofed supplier domains and lookalike addresses turn into very real, very expensive payments.
WHAT YOU GET
Microsoft Defender for Office 365 - properly configured and continuously tuned
We don't ship you a config and walk away. AUCyber owns the policy, the tuning, the SafeLinks/SafeAttachments rules, the Domain-based Message Authentication, Reporting and Conformance (DMARC) alignment and the ongoing response to user reports.
Defender for Office 365 build-out
Anti-phish, anti-spam, anti-malware, SafeLinks and SafeAttachments policies tuned for your tenant.
Impersonation & BEC controls
VIP impersonation protection, lookalike-domain detection and tuned mailflow rules for finance and exec mail.
DMARC, Sender Policy Framework (SPF) & DomainKeys Identified Mail (DKIM) uplift
We get your domains to DMARC reject without breaking legitimate mail - and keep them there.
Quarantine & user-report handling
User-reported phish reviewed by our Security Operations Centre (SOC), with verdicts pushed back into Defender to retrain detection.
Threat hunting on Email telemetry
Defender XDR and Purview telemetry hunted for impersonation, exfiltration and inbox-rule abuse.
Phishing simulations & training
Optional Cyberaware-powered simulations and bite-size training so people are part of the defence.
