Email security & deliverability in Penrose
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 Penrose. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for Penrose businesses
Penrose is one of the central isthmus's main industrial areas, with manufacturers, trade wholesalers, distribution warehouses, engineering shops and building suppliers along Great South Road, Church Street and the surrounding streets. Offices are typically attached to a warehouse or factory floor.
Industrial sites need Wi-Fi that reaches across the racking for scanners and tablets, cabling that survives dust and forklifts, and network links between buildings on the same section. The office side runs accounting, inventory and freight systems that stop dispatch if they go down, so reliable internet and a backup connection are worth having.
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 come to Penrose sites for warehouse Wi-Fi, cabling, scanners and office computers, and fix most everyday problems remotely. Site work is planned around shifts and dispatch times.
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.
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.
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 Penrose 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 Penrose: questions
Our scanners drop out at the back of the warehouse. Can you fix that?
Usually, yes. Racking and stock block signal, so warehouse Wi-Fi needs a survey and access points placed for the aisles rather than the office. We measure coverage and quote the design and installation in writing.
Can you connect our office to a second building on the same site?
We can run cable or fibre between buildings where there is a practical route, or use a point-to-point wireless link where trenching is not worth it. All of it is low-voltage data work, quoted before we start.
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.
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.
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.
