Email security & deliverability in Invercargill
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.
Invercargill is supported remotely. Our technicians are based in Auckland and Hamilton, so onsite work here is planned project work, booked and quoted in advance.
Email security & deliverability for Invercargill businesses
Invercargill is Southland's main city, servicing a large farming region with meat and dairy processing, agricultural services, engineering, heavy industry, education and health, plus the professional firms that support them. Much of the city's professional work is done by small local teams that serve clients across the wider region.
Rural service firms here support clients spread across Southland's farms, many on rural connections, and engineering and processing businesses run workshops and plant alongside office systems. Remote support and cloud systems help firms that find it hard to hire local IT staff.
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.
We support Invercargill businesses remotely for help desk, security, Microsoft 365 and backups. Onsite visits are for planned projects by arrangement and quoted in writing. Equipment for workshops or new offices can be specified remotely and fitted by a local installer.
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.
DMARC rollout
A reporting-only policy first, then a gradual move to quarantine and reject once reports show all your genuine mail passes.
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.
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.
Is it right for your Invercargill 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 Invercargill: questions
We can't find local IT staff. Can remote managed IT work for us?
Yes. Most of the work, from updates and security to helping staff, is done remotely. Physical work is handled with planned visits or a local installer we coordinate.
Do you support farm service businesses?
Yes. We manage laptops and phones for staff working across farms, secure client records and set up file sharing that copes with slow rural connections.
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.
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.
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.
