Acceptable use policy, Corrigan Hale Accountants

Acceptable use policy template with an honest monitoring notice

An acceptable use policy has to say which systems it covers, what staff may and may not do with them, what the organisation monitors, and what happens when the rules are broken. This four page policy for a 28 person accounting firm holding records for 1,900 clients does that, with a monitoring table that says what is logged, for how long, and what is never watched.

Permitted use
Use the firm's systems for firm work. Brief personal use is fine when it does not get in the way of work, cost the firm money, or break section 4: checking the news at lunch, a personal email, paying a bill. Personal files belong on your own device, not the firm drive, and anything you store on firm systems can be seen under section 5.
4
Prohibited use
Never do any of these on a firm system or with firm data:
send client data to a personal email account, or open it on a personal device that is not enrolled with the IT provider
copy client data to a USB drive or to any cloud service the firm has not approved
paste client names, tax identification numbers or financial details into a public AI tool or chatbot
install software, browser extensions or apps without IT approval
share your login, use someone else's, or leave a session open on an unlocked screen
access a client file you are not working on, including for friends or family
view, store or send material that is offensive, discriminatory, pornographic or illegal
try to switch off, get around or test security controls
send client data to a personal email account, or open it on a personal device that is not enrolled with the IT provider
copy client data to a USB drive or to any cloud service the firm has not approved
paste client names, tax identification numbers or financial details into a public AI tool or chatbot
install software, browser extensions or apps without IT approval
share your login, use someone else's, or leave a session open on an unlocked screen
access a client file you are not working on, including for friends or family
view, store or send material that is offensive, discriminatory, pornographic or illegal
try to switch off, get around or test security controls
send client data to a personal email account, or open it on a personal device that is not enrolled with the IT provider

Monitoring notice
The firm monitors its systems to protect client data. This is what is recorded, who can see it and for how long, so nothing is a surprise.
What is logged
Detail
Kept for
Sign ins
Time, device and location of each sign in and failed attempt
12 months
Email
Sender, recipients, attachments and messages flagged by filters
7 years, as records
Web traffic
Sites visited and blocked from firm devices and networks
90 days
File activity
Who opened, changed, shared or deleted each client file
7 years
What the firm does not do
The firm does not record keystrokes, screens or webcams, does not read personal messages on your own phone, and does not track firm phones outside work hours. Logs are reviewed only by the Practice Manager and the IT provider, and only for a security alert, a complaint or a suspected breach.
6
Passwords and sign in
Every firm account uses multi factor authentication with the authenticator app, never a text message code. Passwords are kept in the firm password manager, and the rules are simple:
1.
Use a passphrase of at least 14 characters, such as four unrelated words.
2.
Use a different password for every system, generated by the password manager.
3.
Never write a password down, email it or tell it to anyone, including IT.
4.
Change a password at once if you think someone else has seen it, and tell IT.
5.
Lock your screen whenever you step away, and it locks itself after 5 minutes.
7
Reporting and breaches
Report a lost device, a suspicious email you clicked, or data sent to the wrong person to the Practice Manager straight away, day or night. Reporting fast is never a breach in itself; hiding a mistake is. A breach of this policy is handled under the disciplinary procedure: a first minor breach usually means retraining, a serious one such as sending client data to a personal account can lead to a written warning or dismissal, and the firm may have to tell affected clients and the privacy regulator.
8
Review
The Practice Manager reviews this policy each year with the IT provider, and after any security incident. Questions go to the Practice Manager.

How to adapt this document

First, for a business without client data obligations, cut the prohibited list to what matters to you, such as company accounts and payment systems, and shorten the email retention to your own records policy. Second, if staff use their own phones, add a cross reference to a separate bring your own device policy rather than covering personal devices here. Third, if your monitoring is wider, for example screen recording in a call centre, say so in the table with the reason and retention, because undisclosed monitoring is what turns a policy into a complaint.

Monitoring and privacy rules differ by place

Whether and how an employer may monitor work systems depends on local law. In the UK, the Information Commissioner's guidance on monitoring workers expects employers to be open about monitoring, to have a clear purpose and to keep it proportionate. Other countries, and some states within them, have workplace surveillance laws that require written notice before monitoring starts, and privacy law governs the client data the logs may contain. Check the rules where your staff work before relying on this policy's notice.

What makes this document work

Monitoring is disclosed in full

Clause 5 lists four logs, sign ins, email, web traffic and file activity, with what each records and how long it is kept, from 90 days to 7 years. The callout then says what is never watched: keystrokes, screens, webcams, personal messages, phones out of hours. Staff accept monitoring they were told about.

The prohibitions match an accounting firm's real risks

Eight prohibited uses include sending client data to a personal email account, copying it to USB, pasting tax identification numbers into a public AI tool, and opening a client file you are not working on. Each one is a way client data actually leaks from small firms.

Password rules follow current guidance

Clause 6 asks for a 14 character passphrase, a different password per system from the password manager, and multi factor authentication by app rather than text message. It does not force regular password changes, only a change after suspected exposure, which matches current guidance and stops staff writing passwords down.

Questions people ask

Is it legal to monitor employees' work email and internet use?

Generally yes on work systems, provided staff are told clearly what is monitored and why, and the monitoring is proportionate. Privacy and workplace surveillance laws differ by country and, in some places, by state, and some require written notice in advance. This policy's monitoring table is that notice.

Should an acceptable use policy allow personal use?

Most do, within limits, because a total ban is ignored and then unenforceable. This one allows brief personal use that does not interfere with work, cost the firm money or break the prohibited list, and warns that anything stored on firm systems can be seen. That is realistic and defensible.

Why mention AI tools in an acceptable use policy?

Because pasting client details into a public chatbot sends them to a third party outside the firm's control, and staff often do not see it as sharing. Naming it specifically, as the third prohibited use does, closes a gap older policies did not anticipate. Approved tools with proper terms can be listed separately.

Do staff need to sign an acceptable use policy?

It helps to have a record that each person received and read it, whether a signature, an electronic acknowledgement or a training record. This version has no signature block; firms usually collect acknowledgement through their onboarding or HR system, which keeps the record with the employee file.

What should happen when someone clicks a phishing link?

They should report it immediately, as clause 7 asks, day or night. Fast reporting lets the IT provider reset passwords and check for damage before data leaves. This policy states that reporting is never a breach in itself, because staff who fear punishment hide mistakes, and hidden mistakes cost far more.
