Why this conversation exists
The yard runs on hire desks, invoices and a public site customers already use.
You hire plant. You probably do not employ a CISO. You may have a yard, a depot, a hire desk, Microsoft 365, a local IT firm, and staff who are out more than they are in. None of that requires a six-month security programme. It does mean a few operational facts are worth being honest about.
If somebody convincingly spoofs the hire desk, the problem is not an interesting mail record. It is a machine collected from the wrong yard, or a payment sent to the wrong account.
I start with what a stranger can already see on the public domain you name. That is the honest first step for a plant-hire business, not a product list.
Hire-desk email and hire agreements
Quotes, collection instructions and hire agreements still leave the desk by email. If a customer trusts that address, a convincing fake is an operations problem first. Published mail controls on your domain are part of whether that message looks like you.
Invoices and payment instructions
Bank-detail conversations with customers and suppliers still move by email. A message that “the account has changed” is a finance problem, not an IT curiosity. I can see what the domain publishes. I cannot see who sits on the invoice inbox.
The public website customers already use
Hire enquiries often start on the site. A neglected public surface is already visible to strangers. I only look at the domain you name, after you say I may. Sister companies and anything behind a login stay out of scope.
Depots, remote staff, and a small IT firm
People work from the yard, the road, home and the office on the same domain. A local MSP looking after Microsoft 365 is normal. It is not the same as someone having looked at what the public website publishes.
Telematics, fleet portals and anything behind a login stay unknown unless they have been left on the open internet. I will not invent findings about them.
Brokers and insurers sometimes ask how you handle cyber. That is a conversation. An outside-in look is not an insurance quote, and it does not make you eligible for cover.
If email and the office systems stop, the hire desk stops. I will not open with a ransomware product. If the public surface is neglected, we talk about that first.
