Multi-factor authentication (MFA) protects your firm by requiring a second check beyond the password, usually a quick approval on a phone, before anyone can log in. That means a stolen or guessed password on its own is not enough to reach your Microsoft 365, your email or your hosted desktop. For a contractor handling payments and client data, MFA is one of the strongest and simplest protections available.
Passwords get phished, leaked and reused constantly. MFA is what stops a stolen password becoming a breach. Here’s why it matters.
1. It blocks stolen-password attacks
Most account takeovers start with a password that’s been phished or leaked. With MFA in place, the attacker still can’t get in, because they don’t have the second factor. This alone stops the majority of account attacks.
2. It protects your hosted desktop too
Your hosted desktop holds your finance software and files, so it’s a prime target. MFA in front of it means someone with a stolen password still can’t reach the systems your business runs on.
3. It’s quick once it’s set up well
Modern MFA is usually a tap on a phone app. Set up properly, it adds strong protection with only a moment of effort, so there’s no real friction for your office or site staff.
4. It’s expected by clients and insurers
Main contractors, clients and cyber insurers increasingly require MFA. Having it in place is both good protection and a clear answer when someone asks how you secure access.
A real example: MFA backed by monitoring
We support a security and M&E contractor with MFA across their Microsoft 365 and hosted desktops, and we monitor it too. When a change to one user’s MFA was made alongside risky logins on the same account, we reviewed it and confirmed whether it was genuine or an attacker trying to register their own device, the kind of signal that’s invisible without MFA-change monitoring.
For most building-services and M&E contractors, this sits within fully managed IT at about £45 to £100 per user per month, billed per user, with the security and on-site remote access your teams need built in.
