Email security & deliverability in Epsom
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 Epsom. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Epsom businesses
Epsom is largely residential, but Manukau Road and the Greenlane end carry medical centres, dental practices, specialist rooms, real estate offices and professional services, with several schools and the showgrounds nearby. Many businesses run from converted homes with a small car park out front.
Converted homes bring a familiar set of problems: a router in the old lounge, staff in former bedrooms with poor signal, and a printer cabled to one computer. Health practices also need patient data kept private under the Health Information Privacy Code, which means locked-down devices, proper user accounts rather than shared logins, and tested backups.
Two email problems come up again and again. The first is incoming: a convincing message that looks like it came from a supplier, a courier or the managing director lands in someone's inbox and asks them to sign in, open a file or change bank details. The second is outgoing: your quotes and invoices go to clients' junk folders, or a criminal sends mail that appears to come from your own address.
Technicians attend Epsom practices and offices for network, computer and printer work, while routine requests are handled remotely. We book onsite work at times that suit appointment schedules.
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.
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 Epsom 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 Epsom: questions
Our clinic staff share one login on reception. Should we change that?
Yes. Shared logins make it impossible to see who accessed a record and are hard to secure. We set up individual accounts with quick sign-in options, so staff still move quickly between front desk computers without sharing passwords.
Can you fix Wi-Fi in a converted house used as an office?
Usually with two or three business access points placed where people actually work, connected back to the network by cable where possible. We survey the building first and quote the job in writing.
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.
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.
