AI Security Risks for Smbs 2025. Written for Toronto businesses by Group 4 Networks. The office is 18 King Street East, Suite 1400. Call (416) 623-9677.
The AI risk we actually see in Toronto small firms is not a movie hacker. It is a person pasting a customer list, a contract, or a payroll export into a chat tool on a personal account because it answered faster than the one the company pays for. Group 4 Networks treats that as an access problem. The office is 18 King Street East. We have worked with GTA businesses since 2008, and the pattern showed up as soon as the tools became easy.
The second risk is a confident wrong answer that someone acts on. A draft policy, a customer email, or a number in a quote that the model invented. If nobody checks it against the source file, the mistake leaves the building with your name on it. The control is dull: an approved tool inside the tenant, a rule about what may be pasted, and a person who reads the draft before it is sent. We will help you write the rule in one page. We will not pretend a banner in the lunch room is the control.
Connected apps are the third risk. Someone clicks accept and a new tool can read mail or files. The consent screen is easy to miss. We inventory the apps connected to Microsoft 365, remove the ones nobody can name, and leave the ones a team lead still uses, with a smaller scope if the full mailbox was more than they needed. Guest accounts should not be the ones granting those consents. Admins should be few, and each one should still work at the firm.
Endpoint protection and mail filtering do not understand a prompt. They do understand a laptop that starts encrypting files, or a mailbox rule that appears overnight and forwards mail out. Those controls stay. Adding a chat tool does not retire them. If something is already spreading, the 15 minute P1 response target applies, including after hours. That is a target for a person to start, not a promise that the model can be unplugged from across the city in a minute.
What a small firm can do in a month is short. Ask each lead which tools they already use. Check the tenant for connected apps. Decide what is allowed to see customer data. Turn on multi factor authentication for anyone who can export a list. Write down the approved tool and the date you looked. Call (416) 623-9677 if you want that inventory done from the tenant rather than from a survey people will answer politely and then ignore.
We will not give you a score out of one hundred. We will say which tools are approved, which connections exist, and who can read the prompts if the tool keeps them. Prompts can be as sensitive as the file that was pasted. If the log is sitting in a personal history, that is the finding. The fix is to use the business tenant and to delete the prompt on the same schedule as the document.
Look again next quarter. Teams start pilots without a ticket. A one time survey is stale the month someone adds a login. Put the review on a calendar. The risk did not arrive as a new server in the closet. It arrived as a browser tab, and that is where the check has to look.
