Why BYOD Can Create Security Risks for Real Estate, Accounting, and Legal Firms — and Why Company-Owned Devices Are Safer

Many businesses adopt Bring Your Own Device (BYOD) policies to reduce hardware costs or give employees flexibility. While this can seem convenient, it often introduces cybersecurity and data protection risks that are particularly serious for industries that handle sensitive client information.

For sectors such as real estate agencies, accounting firms, law firms, and other professional services, employee devices often contain confidential financial records, contracts, and personal client information. Without proper controls, these devices can become a major point of vulnerability.

The Type of Data These Industries Handle

Real estate, accounting, and legal businesses deal with large volumes of sensitive and confidential data every day.

Examples include:

• Personal client information, such as names, addresses, and identification documents

• Financial records, tax information, and banking details

• Contracts, agreements, and legal documentation

• Property transaction information

• Internal business communications and client correspondence

  
  

For example, real estate agents regularly access buyer and seller details, contracts of sale, and identity documents. In accounting, firms handle tax records, financial statements, and payroll information. In legal and professional services, teams manage confidential client files, contracts, and sensitive communications.

If this information is exposed or mishandled, it can lead to privacy breaches, regulatory issues, and serious reputational damage.

The Risks of BYOD

When employees use personal laptops or phones for work, business data often ends up stored on devices the company does not fully control.

This can include emails, documents, and access to cloud systems such as document management platforms, accounting software, or CRM systems.

Because the device belongs to the employee, businesses may have limited ability to enforce security standards, such as:

• Encryption

• Endpoint protection

• Device updates and patching

• Remote wipe capabilities

Personal devices are also used for everyday activities such as downloading apps and browsing the internet, increasing the risk of malware or compromised accounts.

The Biggest Risk: When Employees Leave

One of the most common issues with BYOD appears when an employee leaves the business.

If they used their personal device for work, company information may still remain on that device even after their access to systems has been removed. Files may still be stored locally, emails may remain accessible, and documents may have been synced to personal cloud storage.

For a real estate agency, this could mean buyer and seller details remaining on a former employee’s laptop or phone. For an accounting or legal firm, it could involve financial records, tax information, or confidential client documents.

Even if the employee has no intention of misusing the information, the business no longer has control over where that data resides.

Why Company-Owned Devices Are Safer

Providing company-owned and managed devices allows businesses to maintain proper security controls and protect client data.

With company-managed devices, organisations can enforce:

• Security and endpoint protection software

• Device encryption

• Regular updates and patch management

• Access policies and monitoring

• The ability to remotely wipe devices if they are lost or when staff leave

Most importantly, when an employee leaves the business, the company retains full control of the device and can securely remove all client and company data.

If BYOD Is Allowed, It Must Be Properly Managed

Some businesses may still allow BYOD for operational reasons. However, if this approach is used, the device should be fully managed by the organisation while it is being used for work.

This means enrolling the device into the company's device management systems and enforcing security policies. In many cases, the device should be used exclusively for work while under management.

Allowing a device to serve as both a personal and a work device without proper controls creates unnecessary risk for businesses handling sensitive client data.

Protecting Client Data Starts with Securing Devices

For real estate agencies, accounting firms, legal practices, and other professional services businesses, protecting client information is critical. Employee devices are among the most common entry points for data breaches and cyberattacks.

While BYOD may seem convenient, company-owned and managed devices provide far greater security, visibility, and control. For businesses handling sensitive financial, legal, and personal information, this approach significantly reduces the risk of data leakage and cybersecurity incidents.
