Email security & deliverability in Mt Wellington
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 Mt Wellington. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Mt Wellington businesses
Mt Wellington runs from the Sylvia Park retail precinct to large business parks along Mt Wellington Highway and the Sylvia Park Road area, home to distribution centres, head offices, building product suppliers and service companies. Offices range from modern office blocks to warehouses with a mezzanine office.
Companies here often have a mix of corporate-style office space and operational areas, so the network has to handle staff laptops, warehouse scanners, CCTV and meeting room gear without one getting in the way of another. Separating those into their own network segments, with a firewall that is actually managed, is a common first improvement.
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.
Technicians visit Mt Wellington offices and warehouses for networks, Wi-Fi, CCTV and computers, and resolve everyday requests remotely. Larger projects are quoted in writing and scheduled around operations.
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.
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.
Impersonation protection
Rules that flag mail pretending to come from your directors, your domain or lookalike domains with a letter swapped.
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 Mt Wellington 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 Mt Wellington: questions
Our CCTV, scanners and office PCs are all on one network. Should they be split up?
It increases risk and can slow things down. We separate them into their own network segments behind a managed firewall, so a compromised camera cannot reach your finance computers and heavy traffic in one area does not affect another.
Do you install CCTV for business sites?
Yes, we install and maintain business CCTV systems as low-voltage work, including recorders and remote viewing set up securely. Each installation is quoted in writing after a site visit.
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.
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.
