A cyber incident can disrupt daily work, expose customer information, or lock you out of important accounts. Small businesses do not need a complicated security program to reduce common risks. Start with a few consistent safeguards: protect email, keep devices updated, secure accounts, and limit access to sensitive information. These steps help Minneapolis businesses build stronger routines and give employees clear guidance on what to do when something seems wrong.
Secure Business Email
Treat unexpected email as a request to verify, not an instruction to act immediately. Be cautious with urgent payment changes, unfamiliar attachments, and links asking you to sign in. Before sending money or changing bank details, confirm the request through a known phone number or a separate trusted channel. Do not rely on contact information included in the questionable message.
Turn on multifactor authentication for email accounts so a password alone cannot grant access. Use a unique password for each account, preferably stored in a reputable password manager. Make sure the business controls its email domain and account recovery options. Remove former employees’ access promptly, and give each worker an individual account rather than sharing one login.
Protect Computers and Phones
Install operating system, browser, and application updates as soon as practical. Updates often address security weaknesses that attackers may exploit. Enable automatic updates where available, and replace devices that no longer receive security support. Use reputable security software and keep its protections active instead of disabling alerts to avoid interruptions.
Lock screens when stepping away, and require a passcode or biometric unlock on phones and laptops. Avoid using public Wi-Fi for sensitive work unless you connect through a trusted, business-approved secure connection. Keep work devices physically secure, especially in shared spaces, vehicles, and during travel. Back up important files regularly to a protected location and check that you can restore them.
Strengthen Accounts and Access
Use multifactor authentication on financial, email, cloud storage, and customer-management accounts. Choose a different, long password for each service. A password manager can create and store unique passwords without requiring staff to remember them all. Never send passwords through email or chat, and change credentials promptly if you suspect an account has been exposed.
Give employees access only to the systems and information needed for their jobs. Review who has access when roles change and when someone leaves. Set up separate administrator accounts for system changes, rather than using administrator privileges for routine work. Keep an up-to-date list of key accounts, who owns them, and how to contact the provider if access is lost.
Handle Customer Information Carefully
Collect only the customer information your business needs, and explain how you use it. Store sensitive records in approved, access-controlled systems rather than personal email accounts or unprotected spreadsheets. Avoid keeping payment card details unless your business has a clear, secure reason and the right processes. Follow the requirements that apply to your industry and the services you use.
Create a simple response plan before an incident occurs. Identify who employees should contact if they click a suspicious link, lose a device, or notice unusual account activity. Preserve relevant messages and details, then secure affected accounts from a trusted device. Contact your technology provider, financial institution, or appropriate authorities as needed, and avoid promising customers a specific outcome before you understand what happened.
Start by enabling multifactor authentication, updating devices, and reviewing who can access business and customer information. Then make these checks part of regular operations and ensure every employee knows how to report a concern.
