Email security & deliverability in Hamilton
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 Hamilton. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Hamilton businesses
Hamilton is the Waikato's commercial centre, with professional firms, government agencies, banks and consultancies along Victoria Street and Anglesea Street, a large health sector around the hospital, the university and polytechnic, and agribusiness, engineering and logistics companies across the city.
Central city offices range from modern buildings to older blocks off Victoria Street with tired cabling, and many firms serve rural clients, so staff travel and need secure access to files from farms, cars and home. Agribusiness and rural professional firms also hold detailed client and financial records that call for good sign-in security and tested backups.
We put those records in place carefully. Every service that sends as you, such as your accounting package, website forms and newsletter tool, is found and included first, so tightening the policy doesn't block your own invoices. Then we add filtering for incoming mail and show staff how to report anything odd. Finally we keep watching the DMARC reports, so a new service sending as you, or someone trying to forge your address, is spotted and dealt with rather than discovered when a client complains.
Office IT has technicians working onsite in Hamilton, visiting offices for setups, networks and hardware, with remote support for everyday requests. Projects are quoted in writing before work begins.
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.
DKIM signing
Microsoft 365 and your other sending services set to sign outgoing mail with your domain, so receivers can verify it.
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.
SPF records
One correct SPF record listing every service that legitimately sends for you, kept within the lookup limits that break many records.
External sender warnings
A clear banner on mail from outside the company, so a message using the boss's name from a free email account stands out.
Is it right for your Hamilton 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 Hamilton: questions
Do you have technicians in Hamilton or just Auckland?
We provide onsite support in Hamilton as well as Auckland, so Hamilton offices get technician visits for installs and hands-on faults. Most day-to-day help is handled remotely, which is usually the quickest fix.
Our staff visit rural clients. How do they access files securely on the road?
Files live in Microsoft 365, laptops are encrypted and managed, and multi-factor sign-in protects every account. Staff can work from a farm office or vehicle on mobile data without carrying copies on USB sticks.
What does it cost?
Email security is included from the Managed plan at $119 per user per month plus GST. A one-off domain records and deliverability fix outside a plan is quoted in writing first.
Can someone really send email as us?
Without DMARC at a strict policy, yes, it is surprisingly easy. Once the policy is enforced, most receiving mail systems will refuse those forged messages.
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.
