You protect a contractor’s finance and payroll systems with tight access controls, multi-factor authentication, application allowlisting, managed email security, a firm payment-verification rule, and tested backups. Contractors move money and are heavily targeted by invoice and payment fraud, so the systems that handle your accounts and pay runs need real, layered protection, not just a password.
Your finance data and your bank payments are exactly what attackers are after. Here’s how to keep them safe.
1. Control who can reach finance systems
Access to QuickBooks, payroll and banking should be limited to the people who need it, protected by MFA, and removed promptly when someone leaves. Tight access is the foundation of protecting your money.
2. Lock down the devices and software
Application allowlisting means only approved software runs on the machines used for finance, so malware and unknown programs are blocked. Combined with endpoint protection, it keeps the systems handling your money clean.
3. Secure email and verify payments
Most fraud starts with email. Managed filtering and impersonation protection stop much of it, and a firm rule to verify any change of bank details by phone, never by email, protects your payments at the point it matters most.
4. Back it up
Tested, isolated backups of your finance and payroll data mean a mistake, a failure or an attack never costs you your records. Being able to recover quickly is part of protecting the business.
A real example: an attack caught early
We support a security and M&E contractor where our monitoring flagged a suspicious login on a finance user’s account, from an unexpected location, along with a change to their security settings. We investigated and locked it down before any harm was done. Catching that early is exactly what protects a contractor’s money.
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.
