Estate agents handle some of the most sensitive data in the UK property market — and most independent agencies have almost no IT security in place.

That combination makes them an increasingly common target for cybercriminals.

What Data Do Estate Agents Hold?

Think about everything that flows through an estate agency in a typical month:

Every one of those data categories is valuable to a criminal. Some directly enable financial fraud. Others enable identity theft. All of them fall under GDPR.

The Most Common Attack Against Estate Agents

The attack we hear about most frequently in the property sector is email interception — sometimes called a Business Email Compromise (BEC) attack.

Here’s how it works. A criminal monitors the email communications between an estate agent, their client, and the solicitor handling a transaction. At the point where payment details are exchanged — often a completion date when significant funds are moving — the criminal sends an email from a spoofed or compromised address, redirecting the payment to a fraudulent account.

By the time anyone realises what’s happened, the money is gone.

This attack works because email systems at small agencies are often poorly configured. No multi-factor authentication, no email authentication records, no monitoring. The criminal’s fake email is indistinguishable from the real thing.

What Else Are Estate Agents Vulnerable To?

Beyond email fraud, independent estate agents commonly have:

Shared login credentials: Staff sharing a single username and password for key systems. One person leaving means changing credentials everywhere — if anyone remembers to do it.

Unsecured remote access: Many agencies moved to remote working arrangements and set up remote desktop or VPN access quickly during 2020. Several years later, those setups often haven’t been reviewed or secured properly.

Outdated software: Property management and CRM software that hasn’t been updated, running on operating systems that are no longer receiving security patches.

No backups: If ransomware hits and your data is encrypted, a backup is the difference between recovering in hours and losing everything.

What Does GDPR Mean for Estate Agents?

Estate agents are data controllers under GDPR. That means you have a legal obligation to protect the personal data you hold, report breaches within 72 hours, and be able to demonstrate that you’ve taken appropriate technical measures to keep data secure.

An ICO investigation following a breach will look at whether you had reasonable security measures in place. “We didn’t know” and “nobody told us” are not defences.

A security audit is one of the most straightforward ways to demonstrate that you’ve taken reasonable steps.

What Does a Security Audit Look Like for an Estate Agent?

Most of the work is done remotely. We review your network configuration, email setup, remote access arrangements, and software patch status. We check which accounts exist and whether former employees still have access. We look at how your client data is stored and who can access it.

The output is a plain-English report — not a technical document — that tells you exactly what we found, what the risk is, and what to do about it.

For most independent agencies with under 20 staff, this takes a few hours and costs £500.
