Layered inbound email defence stops phishing, malicious attachments and malicious links before your people ever see them. DMARC, SPF and DKIM alignment stops criminals sending email that claims to be from your domain in the first place. Most Australian businesses have neither properly configured, which leaves both directions of the mail flow exposed.
Business email compromise and invoice fraud cost Australian organisations real money every year, and the pattern is almost always the same: a convincing email, a payment redirected, discovered too late. The reverse problem is just as damaging. If your domain isn't properly authenticated, criminals can send phishing email that appears to come from you, landing in your customers' and suppliers' inboxes with your name attached. That damages trust, deliverability and, increasingly, your standing against Essential Eight and cyber insurance expectations covered in our compliance & security auditing work. Fixing both directions at once is the only complete answer.
A single convincing phishing email that reaches the wrong inbox can lead to credential theft, ransomware deployment or a fraudulent payment. Layered filtering, sandboxing and link rewriting stop the overwhelming majority before a human ever has to make the right call under pressure.
Without DMARC alignment, nothing stops a criminal registering a look-alike sending path and emailing your customers as "you". The damage lands on your reputation, not theirs, and it's often discovered only after a customer calls to ask if you really sent that invoice.
Email hardening is increasingly a named expectation in cyber insurance questionnaires and security frameworks. "We use Microsoft 365" is no longer treated as a sufficient answer; a documented DMARC policy and inbound filtering strategy is.
We design, implement and continuously manage the technical controls, then connect what they find into the rest of your security stack rather than leaving it as a standalone dashboard nobody checks.
Every legitimate sending source behind your domain identified and authorised, DKIM signing configured, SPF records tightened, and a DMARC policy staged safely from monitor through to full enforcement.
Attachments detonated in an isolated environment before delivery, catching malicious payloads that signature-based scanning alone misses.
Links rewritten and re-checked at the moment they're clicked, not just at delivery, so a page that turns malicious after arriving in the inbox is still caught.
Impersonation and lookalike-domain detection tuned to your executive and finance team names, the accounts targeted most often in invoice fraud and payment-redirection attempts.
A managed quarantine with clear release workflows, plus regular reporting on what was blocked, what was released and how DMARC alignment is trending over time.
A one-click "report phishing" button feeds real staff-reported email straight into our review queue, and the patterns we see shape the next round of Security Awareness Training and Phishing Simulation campaigns.
Email threat signals, quarantine activity and DMARC alignment failures all feed into the Security Operations Centre, so an email-borne attack is triaged alongside every other signal in your environment, not in isolation.
Start with a free security audit. We'll review your current DMARC posture, inbound filtering and where the gaps sit, then tell you honestly what needs fixing first.
