Email security & deliverability in Silverdale
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 Silverdale. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Silverdale businesses
Silverdale has grown quickly beside State Highway 1 at the start of the Hibiscus Coast, with new business parks, trade suppliers, storage and logistics, a retail centre and medical services serving the Millwater and Orewa growth areas. Many buildings are recent and occupied by businesses that relocated north.
New commercial buildings usually come with fibre and a blank comms room, which is the ideal time to plan cabling, firewall, Wi-Fi and CCTV properly rather than adding them piecemeal. Businesses relocating here also need their internet ordered early, because a new connection can take a while to activate in a just-finished building.
Both have the same root. Email was designed long before anyone worried about forgery, so proving who sent a message depends on a handful of DNS records and filtering settings that most small businesses have never had set up properly. SPF lists the services allowed to send for you, DKIM signs your messages and DMARC tells other mail servers what to do with anything that fails. Big mail providers now expect all three from business senders.
Our Auckland technicians travel to Silverdale for fit-outs, network installs and ongoing onsite work, with everyday support provided remotely. New premises setups are planned and quoted in writing.
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.
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.
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.
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.
Is it right for your Silverdale 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 Silverdale: questions
We're fitting out a new building in Silverdale. When should IT be involved?
Before the walls are lined. We can specify data points, the comms cabinet, Wi-Fi locations and CCTV positions so the cabling goes in once. Our design and installation are quoted in writing.
How early should we order internet for a new building?
As soon as you have an address and a move date. New connections can take several weeks, so we order early and arrange a temporary mobile connection if fibre is not ready in time.
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.
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.
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.
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.
