Email security & deliverability in Highbrook
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 Highbrook. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Highbrook businesses
Highbrook Business Park is a master-planned estate beside the Tamaki River with direct motorway access, home to national distribution centres, corporate head offices, logistics operators and manufacturers in large modern buildings. Many tenants run bigger teams and multiple sites around the country.
Buildings at Highbrook typically have good fibre and structured cabling, so the work is about scale and consistency: managing many devices, linking the Auckland site securely with branches elsewhere, high-density Wi-Fi in large warehouses and meeting rooms that work for national video calls. Security reporting and documented processes are often expected by head office or insurers.
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.
Our technicians attend Highbrook sites for rollouts, network and Wi-Fi projects, and provide remote support to staff wherever they are. Regional branches are supported remotely with planned visits by arrangement.
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.
Junk folder fixes
We trace why your mail is being filtered, from missing records to a listed address or a website form sending as you, and correct it.
DKIM signing
Microsoft 365 and your other sending services set to sign outgoing mail with your domain, so receivers can verify it.
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.
Impersonation protection
Rules that flag mail pretending to come from your directors, your domain or lookalike domains with a letter swapped.
DMARC rollout
A reporting-only policy first, then a gradual move to quarantine and reject once reports show all your genuine mail passes.
Is it right for your Highbrook 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 Highbrook: questions
We have an Auckland site and branches around NZ. Can you support all of them?
Yes. Auckland and Hamilton sites get onsite technicians, and other branches are supported remotely with planned visits for project work. Every site gets the same setup and security standards.
Can you roll out new laptops to a large team without disrupting work?
We prepare and configure devices in advance, then swap them in batches with each person's files and settings ready. The rollout plan and price are agreed in writing first.
Why does our email go to junk?
Common causes are a missing or broken SPF record, no DKIM signing, a website or app sending as your domain without permission, or a shared sending address with a poor reputation. We check each one and fix the cause.
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.
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.
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.
