Email security & deliverability in Onehunga
Email is where most attacks start and where most business is still done. We filter out the phishing and fake invoices before staff see them, lock down your domain so nobody else can send as you, and fix the settings that send your own mail to clients' junk folders.
Onsite technicians cover Onehunga. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Onehunga businesses
Onehunga combines a busy town centre on Onehunga Mall with industrial and logistics businesses along Neilson Street and nearby Te Papapa, where manufacturers, importers and trade suppliers operate close to the motorway and port links. Professional offices and retail cluster around the mall.
Firms near Neilson Street often run warehouse and office side by side, with freight and inventory software that needs a dependable connection and scanners that need solid Wi-Fi. Town centre businesses tend to be smaller, with a few computers, cloud accounting and a router that has not been touched since it was installed.
Two email problems come up again and again. The first is incoming: a convincing message that looks like it came from a supplier, a courier or the managing director lands in someone's inbox and asks them to sign in, open a file or change bank details. The second is outgoing: your quotes and invoices go to clients' junk folders, or a criminal sends mail that appears to come from your own address.
Onehunga businesses get technician visits for warehouse, office and shop work, with remote help for daily requests. We plan site visits around trading and dispatch hours.
What's included
Phishing and malware filtering
Incoming mail scanned for malicious links, attachments and fake sign-in pages, with links checked again when they are clicked.
SPF records
One correct SPF record listing every service that legitimately sends for you, kept within the lookup limits that break many records.
DMARC rollout
A reporting-only policy first, then a gradual move to quarantine and reject once reports show all your genuine mail passes.
Impersonation protection
Rules that flag mail pretending to come from your directors, your domain or lookalike domains with a letter swapped.
DKIM signing
Microsoft 365 and your other sending services set to sign outgoing mail with your domain, so receivers can verify it.
Report-a-scam button
A simple way for staff to send a suspicious email to us for checking, so problems get reported rather than quietly deleted.
Is it right for your Onehunga office?
Email security is worth a look if:
- Clients tell you your invoices or quotes end up in junk
- Someone received a fake invoice that appeared to come from your address
- Staff are getting convincing fake Microsoft sign-in emails
- You don't know whether your domain has SPF, DKIM or DMARC
- A large client or bank has asked you to set up DMARC
How getting started works
- Free IT health check. We look at your devices, accounts, backups and network and tell you what we find, in plain English.
- Clear proposal. A written monthly price per user and a list of any fixes, with nothing hidden.
- Handover. We collect admin access and documentation from your current provider and keep your team working.
- Day-one fixes. Security gaps, failed backups and urgent risks are dealt with first.
Email security & deliverability in Onehunga: questions
We're a small importer with a warehouse and a few office staff. What do we need?
Typically a business firewall, Wi-Fi that covers the warehouse, managed laptops with backups and secure Microsoft 365. We start with a health check of what you have and recommend changes in priority order.
Is it worth having a backup internet connection?
If losing the internet stops orders, dispatch or payments, it usually is. A mobile backup that switches over automatically is affordable for most small sites, and we confirm the signal at your premises before quoting.
How long does it take to set up?
Filtering and records are usually set in a day or two. Moving DMARC to full enforcement normally takes a few weeks of watching reports, so nothing legitimate is caught.
Isn't Microsoft 365's built-in filtering enough?
It catches a lot, but the default settings are not as strict as they could be. We review and tighten them, and on the Managed and Complete plans add extra email security and phishing filtering.
Will turning on DMARC stop our own emails?
It can if it is rushed. That is why we start in reporting mode, find every service sending as you and only tighten the policy when the reports show your genuine mail passing.
What are SPF, DKIM and DMARC in plain English?
SPF is a list of who can send email for your domain. DKIM is a digital signature on each message. DMARC ties them together and tells receiving servers whether to accept, quarantine or reject mail that fails, and sends you reports about it.
