Bring your own device sounds simple. Team members already have a laptop or phone they like, the business avoids buying another device, and everybody gets on with work.
For some businesses that is perfectly workable. For accounting firms, legal practices and other professional services businesses handling sensitive client information, it can also create a mess that is much harder to manage than it first appears.
The problem is not that personal devices are automatically insecure
A personal laptop can be perfectly well maintained. A company-owned laptop can also be badly configured. Ownership by itself is not the security control.
The real difference is how much control the business has over the device. Can it require updates? Can it enforce encryption? Can it see whether security software is healthy? Can access be removed quickly when somebody leaves? Can the device be supported without mixing business and personal information?
That is where company-owned devices are usually easier to manage.

Why BYOD gets harder in professional services
Client information ends up on a device the business does not fully control
Even when most work happens in Microsoft 365 or another cloud system, local files, email attachments, browser downloads and cached information can still end up on the device.
If the laptop belongs to the employee, the business needs a clear answer to what happens to that data when the person leaves, the device is lost, or the laptop is later handed to a family member.
Security standards become inconsistent
With company-owned devices, the business can set a baseline and apply it consistently. That might include encryption, endpoint protection, patching, device management, browser settings and restrictions around local administrator access.
With BYOD, the business either has to enforce similar controls on equipment it does not own or accept that each device may be configured differently.
Offboarding is much cleaner with business-owned equipment
When somebody leaves, company-owned equipment can be returned, checked, wiped and reassigned. Access can be removed and the business has a fairly clear endpoint.
With a personal device, you still need confidence that business data, cached credentials and applications have been removed without touching the employee’s personal information. That is possible, but it needs to be designed properly rather than improvised on the person’s last day.
Support gets awkward
If a personal laptop starts failing during a busy period, who owns the problem? Is the IT provider expected to repair somebody’s home computer? What happens when personal software conflicts with business software? What if the device is too old to meet the business standard?
Those questions sound minor until somebody cannot work. A company-owned device gives everyone a much clearer boundary.
Does that mean BYOD should be banned?
Not necessarily. Phones are the obvious example. Plenty of businesses allow team members to use a personal phone for Microsoft 365, MFA or selected business applications without giving the business control over the entire device.
The important part is deciding what business data the device can access and what controls are required. Microsoft Intune and similar device-management tools can help separate or protect business information without treating a personal phone exactly like a company laptop.
For laptops and desktops used as the main work device, we generally think company ownership is the cleaner option for professional services firms. The cost of the hardware is usually small compared with the time spent supporting inconsistent devices or dealing with uncertainty around client data.

A sensible middle ground
A fairly practical model is:
Company-owned laptops and desktops for people doing normal day-to-day work, particularly where they handle sensitive client information.
Controlled personal mobile access where there is a genuine benefit, with appropriate Microsoft 365, identity and application controls around the business data.
Exceptions handled deliberately rather than allowing any device simply because somebody already owns it.
If you already use BYOD, start by understanding what you have
You do not need to replace every device tomorrow. Start by working out which personal devices have access to business systems, what information can be stored locally, whether those devices are patched and protected, and how access would be removed if the person left today.
If the answers are unclear, that is usually the useful finding. From there you can decide which devices genuinely need to become company-owned and where managed personal access still makes sense.
