Email Security That Actually Stops Phishing & Fake Invoices
Worried that one fake supplier email or one clicked link could cost your business tens of thousands?
We protect Australian businesses — typically 3–100+ mailboxes — with layered email security: advanced filtering, impersonation protection, MFA, SPF/DKIM/DMARC, mailbox backup and short monthly staff training. Tool-agnostic. Australia-wide. No magic boxes.

If Any of These Sound Familiar, We Should Talk
These are the email-security gaps we walk into almost every week.
Fake invoice and supplier-impersonation emails getting through to finance
Staff getting tricked by phishing emails that look genuine
A staff mailbox got compromised and you are not sure how far it spread
Spam and junk filling inboxes — real emails getting lost in the noise
No DMARC, SPF or DKIM — your domain can be spoofed by anyone
No visibility of who clicked, who reported, or what was quarantined
A Layered Email Defence That Actually Works
Six capabilities that, together, cover everything an Australian SMB needs to take email security seriously.
Advanced Email Filtering
- Inbound filtering for spam, malware, phishing and BEC
- Sandbox detonation for suspicious links and attachments
- Quarantine, release and reporting workflows your team will use
Impersonation & BEC Protection
- Detect spoofed CEO, supplier and finance emails
- Catch lookalike domains and display-name impersonation
- Block fake invoice and payment-redirect attempts
Domain Authentication (SPF, DKIM, DMARC)
- Stop attackers spoofing your domain to your own clients
- DMARC reporting so you actually see who is sending as you
- Set policy from monitor through to reject — properly, in stages
MFA & Mailbox Hardening
- MFA on every mailbox — no exceptions, no legacy bypasses
- Risk-based sign-in policies for suspicious logins
- Disable legacy email protocols that bypass MFA entirely
Security Awareness Training
- Short monthly micro-training your team will actually finish
- Simulated phishing campaigns with reporting on who clicked
- A "Report Phish" button in every inbox — used, tracked, actioned
Mailbox Backup & Recovery
- Cloud mailbox backup — mail, drives, document libraries and chat
- Granular restore — single email, folder or full mailbox
- Tested restores — not just "we have backups somewhere"

Why Australian Businesses Choose Netluma IT for Email Security
The things our security clients tell us actually matter — once they have moved off the spam-filter-only mindset.
Layered, not single-product
Filtering, impersonation protection, MFA, DMARC, training and backup — together. One layer slips, the others catch it.
You actually use what you pay for
Most premium business licences already include serious email security features. We turn on and configure what you already own first, before recommending any new spend.
Plain-English reports
Every health-check comes back as a plain-English summary your leadership team can read in 10 minutes — what is at risk, what we recommend, in what order.
Australian based, senior engineers
Direct access to a senior security engineer — no offshore tier-one call centre, no script-reading. Same engineer plans, deploys and supports.
Training your team will actually do
Five-minute monthly micro-training — not a 90-minute corporate compliance module nobody finishes.
Visibility from day one
You get a dashboard showing what was blocked, what was clicked, what was reported and what was quarantined — every month.
We Are Not the Right Fit If…
We would rather be honest up front than waste your time.
- You want a magic box that "stops phishing" with no policy or training
- You are not willing to roll out MFA on every staff mailbox
- You want the cheapest spam filter, not a properly layered email defence
- You only have 1 mailbox — most of what we do does not apply at that size
