Protecting Your Practice: A Cybersecurity Guide for Attorneys, Accountants, and Advisors

If you run a professional practice, your clients trust you with some of the most sensitive information they have. Tax returns. Account numbers. Estate plans. Settlement details. Investment strategies.

Most of it moves through email.

That makes your practice a natural target, and not because you've done anything wrong. Scammers go where the valuable information is, and they know that busy professionals and their clients exchange it every day.

Your IT person keeps the office running. That's not the same thing.

Many practices have an IT person or company, and that's a good thing. They keep the computers working, set up the printer, and fix things when they break.

But keeping things running isn't the same as protecting them. Break/fix support (help that shows up when something stops working) rarely includes watching for threats, protecting the personal phones your team uses for work, or securing the home networks people log in from.

Those gaps are where a lot of today's problems start.

Where practices get hit

Payment and wire instruction fraud. A client gets an email that looks exactly like it came from your office: same name, same signature, same tone. It says your bank details have changed and asks them to send the next payment to a new account. Sometimes it arrives inside a real email thread, because someone got into a mailbox and waited for the right moment. This is often called business email compromise: a scam where someone gets into, or convincingly imitates, a business email account to redirect money.

Impersonation inside the office. A staff member gets an urgent message that appears to come from you, asking them to send a file, buy gift cards for a client, or move money before the end of the day. AI now writes these messages cleanly enough that the old warning signs, like typos and odd phrasing, are gone.

AI tools used with client information. Your team is probably already using AI to draft letters, summarize documents, or clean up spreadsheets. AI can be a real help in a practice. But if someone pastes a client's financial details into a free tool, that information may be stored somewhere you don't control.

Personal devices doing business work. The phone that gets client emails at 9 p.m. is often the same phone the kids borrow for games. If it isn't protected, it's a way in.

Home networks. Anyone who works from home is connecting your client files through their home Wi-Fi, along with the smart TV, the thermostat, and every other device in the house.

Questions to ask your IT provider

A good IT provider will welcome these questions. Their answers tell you where the gaps are.

• Is anyone watching for threats on our devices, or do we only hear about problems once something breaks?
• Are the personal phones and laptops our team uses for work protected, or only the office computers?
• Is our email protected against impersonation and fake payment requests, and is multi-factor authentication turned on for everyone?
• What happens if someone on our team clicks a bad link at home, on their own Wi-Fi?
• Who protects my personal email and my family's devices, separate from the business?

That last question is one many owners haven't thought about, and it's often where the owner is most exposed.

Your clients are part of your security

Here's a piece that often gets missed. When the advisor is protected but the client isn't, the client becomes the weak point.

If a client's free email account is compromised, a scammer can read your correspondence with them, learn how you work, and send them a convincing fake from "you." Your systems never had to be touched.

That's why the strongest practices also help their clients understand the basics.

A short note at the start of every engagement goes a long way: how you'll communicate, how payment instructions will be shared, and what to do if something ever looks different. Clients appreciate it. It tells them you take their information as seriously as they do.

What to do in your practice

For email:

• Use private, protected email for client communication, not free accounts.
• Turn on multi-factor authentication for every account. That's a second check, like a code sent to your phone, before anyone can log in, even with the right password.
• Tell your clients, in writing, that you will never change payment instructions by email. Ask them to call you at a number they already have if they ever receive a message that says otherwise.

For devices:

• Protect every device that touches client information, including personal phones and laptops.
• Make sure protection is monitored and kept up to date, not installed once and forgotten.

For networks:

• Secure the office network, and talk with your team about their home Wi-Fi.
• Keep work devices separate from the smart devices in the house where you can.

For people:

• Set a simple rule: any request to move money or change payment details gets confirmed by phone, every time, no matter who it appears to come from.
• Agree on which AI tools your team can use and what never goes into them: client names, account numbers, Social Security numbers, passwords.
• Talk about scams openly. Your team should feel comfortable saying, "This looks off," without worrying about looking foolish.

Protecting the business and the person behind it

Your practice and your personal life are more connected than they look. The same person reads client email and family email, often on the same phone, often from the same kitchen table.

Frequently Asked Questions

What is business email compromise?

Business email compromise is a scam where someone gets into, or convincingly imitates, a business email account to redirect money or steal information. A common version tells a client that payment details have changed and asks them to send funds to a new account.

How can a law firm or accounting practice prevent wire fraud?

Confirm every request to change payment details by phone, using a number you already have. Tell clients in writing that you will never change payment instructions by email, and turn on multi-factor authentication for every email account in the practice.

Isn't my IT provider already handling cybersecurity?

Many IT providers focus on keeping systems running and fixing problems when they break. That doesn't always include watching for threats, protecting personal phones used for work, securing home networks, or protecting the owner's personal email. Asking your provider directly is the best way to find the gaps.

Should professionals let staff use AI tools with client information?

AI can help a practice work faster, but client information should stay out of free AI tools. Set clear rules on which tools are approved and what never goes into them, such as client names, account numbers, Social Security numbers, and passwords.

Why does my clients' cybersecurity affect my practice?

If a client's email account is compromised, a scammer can read your correspondence, learn how you work, and send the client a convincing fake message from you. Your own systems don't have to be breached for your clients to lose money.
