Email security & deliverability in Cambridge
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 Cambridge. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Cambridge businesses
Cambridge is a Waikato town about 20 minutes southeast of Hamilton on the expressway, known for thoroughbred breeding and equestrian businesses, with a strong professional services, retail and hospitality centre and many rural service firms serving surrounding dairy farms.
Firms in town usually have fibre, but clients and staff on studs and farms around Cambridge may rely on fixed wireless or satellite, and equine and farm businesses need Wi-Fi that reaches stables, sheds and offices spread across a property. Professional practices hold client financial and property records that need solid security.
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.
Cambridge visits are booked from Hamilton for installs, networks and onsite faults, and everyday support is done remotely. Rural property work is surveyed and quoted first.
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.
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.
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.
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.
Is it right for your Cambridge 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 Cambridge: questions
Can you get Wi-Fi to stables and sheds on our property near Cambridge?
Yes, using point-to-point wireless links or outdoor-rated cabling to buildings, with access points where staff need coverage. We survey the property and quote the low-voltage work in writing.
Do you come out to Cambridge or only support remotely?
Both. Technicians travel from Hamilton for planned visits and hands-on work, and most everyday issues are solved remotely.
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.
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.
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.
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.
