One diverted closing can end a brokerage.
The FBI logged $275.1 million in real estate fraud losses across 12,368 complaints in 2025. Business email compromise — the mechanism behind most wire diversions — accounted for $3.04 billion on its own.
Attackers do not need to breach you. They just need to read your email.
Real estate is targeted because the transaction is public, the timing is predictable, and the sums are large and moved once. An attacker who gets into a single mailbox — agent, broker, title, or the client's own — can watch a closing approach and send wiring instructions at exactly the right moment, from a thread that already exists.
The buyer follows instructions that look identical to every other message in the chain. The money is gone within hours, and recovery past the first day is unlikely. Nothing was hacked in the way people picture it. Someone was reading the mail.
Why the usual advice does not hold up
"Call to verify wiring instructions" is good advice and it is not sufficient. If the attacker is inside the thread, they have your signature block, your phrasing, and often the phone number the client will call. Verification only works when the number comes from somewhere the attacker does not control.
The controls that actually break this attack are upstream of the wire: multi-factor authentication that resists interception, alerting on mailbox forwarding rules, detection of impossible-travel sign-ins, and a staff who recognise the pattern. Most of that is configuration you are already paying Microsoft for and probably have not switched on.
Protect the transaction, not just the laptop.
Microsoft 365 hardening
MFA, conditional access and the tenant settings that stop mailbox takeover — the root cause of nearly every wire diversion.
Mailbox rule monitoring
Alerting when forwarding or hiding rules appear, which is the first thing an attacker sets up and the last thing anyone checks.
Email security and impersonation defense
Filtering for lookalike domains and display-name spoofing aimed at your agents and your clients.
Agent security training
Ongoing training built around wire fraud and closing-day pressure, not generic phishing slides.
Managed devices for a mobile team
Agents work from cars, closings and open houses. Managed, patched and encrypted wherever they are.
Backup and fast recovery
Transaction files, contracts and email backed up with tested restores, so a ransomware event is a delay and not a disaster.
Built for a team that is never in the office.
Brokerages are not typical small businesses. Headcount moves constantly, most of the team is independent, devices are personally owned as often as not, and the busiest moments are exactly when nobody has time for an IT problem.
We support Oklahoma City brokerages with that shape in mind — fast onboarding and offboarding as agents come and go, unlimited business-hours helpdesk so an agent at a closing gets a person, and security that works on devices you do not own outright.
Agent turnover handled
Onboarding and offboarding as a routine, so a departing agent's access actually ends when they do.
Support when it is urgent
Unlimited business-hours helpdesk. Closing-day problems do not queue behind ticket triage.
Security that fits BYOD
Protection on personally owned devices without taking over the whole phone.
Check your exposure before a closing does it for you.
We will review your Microsoft 365 tenant for the specific gaps that enable wire fraud — MFA coverage, forwarding rules, sign-in risk, impersonation protection — and show you exactly what an attacker would find. Most of what we recommend costs configuration time, not licence spend.
