Most small businesses don’t get breached through some advanced attack. They get breached through a default password nobody changed, a laptop that hasn’t been updated in months, or an employee who clicked a convincing email. The good news is that the fixes for those problems are cheap, and most are free.
Change every default password
Routers, printers, cameras, and network storage devices often ship with admin passwords anyone can look up online. Log into each device and set a unique, long password. Store them in a password manager rather than on a sticky note.
Separate guest Wi-Fi from business Wi-Fi
Almost every modern router supports a guest network. Put visitors, personal phones, and smart-home gadgets on it, and keep company computers and file storage on the main network. If a guest device is infected, it can’t reach your business data.
Turn on automatic updates everywhere
Windows, macOS, browsers, and router firmware all receive security patches. Enable automatic updates, and check your router’s admin page every few months, since many routers don’t update themselves.
Use multi-factor authentication (MFA)
Turn on MFA for email, banking, and any cloud accounts like Microsoft 365 or Google Workspace. A stolen password is far less useful to an attacker when they also need a code from your phone.
Back up with the 3-2-1 rule
Keep three copies of important data, on two different types of storage, with one copy offsite or in the cloud. A network-attached storage (NAS) device plus a cloud backup covers this for most small offices. Test a restore occasionally, because a backup you’ve never restored is a guess.
Train people to spot phishing
Phishing is still the most common way attackers get in. Teach your team to check the sender’s actual email address, hover over links before clicking, and be suspicious of urgent requests for payments or passwords. A 15-minute conversation once a quarter goes a long way.
Consider a business-grade firewall as you grow
Consumer routers are fine for very small setups. Once you have several employees or sensitive customer data, a business firewall from a vendor like SonicWall or Fortinet adds content filtering, intrusion prevention, and VPN access for remote staff.
Know who to call
Decide ahead of time what you’ll do if something goes wrong: who to contact, how to disconnect an infected machine, and where your backups are. Having that plan written down turns a crisis into a checklist.
