Cyberattacks on small businesses rose by 43% last year. Yet many business owners still assume they're too small to be a target. The truth is the opposite — smaller businesses are often easier targets precisely because they have fewer defences. The good news? The most effective protection doesn't require a big budget. It requires good habits.
Our engineers have put together the ten habits that make the biggest difference — habits we implement for every client we work with.
Use strong, unique passwords for every account
Reusing passwords is one of the most common ways businesses get compromised. If one account is breached, every other account with the same password is at risk. Use a password manager like Bitwarden or 1Password to generate and store unique passwords for every service.
Enable multi-factor authentication (MFA) everywhere
MFA adds a second layer of security beyond your password. Even if a hacker gets your password, they can't log in without the second factor — usually a code sent to your phone. Enable it on email, banking, Microsoft 365, and any cloud service you use.
Keep all software and systems updated
Security patches fix known vulnerabilities that hackers actively exploit. Delaying updates — even by a few weeks — leaves your systems exposed. Enable automatic updates where possible, and have a managed IT partner handle patching for your servers and business systems.
Train your staff to spot phishing emails
Over 90% of cyberattacks start with a phishing email. Train your team to look for suspicious sender addresses, unexpected attachments, and urgent requests for login credentials or payments. Run regular phishing simulations to keep awareness sharp.
Back up your data — and test your backups
Ransomware attacks encrypt your files and demand payment for the key. A reliable, tested backup means you can restore without paying. Follow the 3-2-1 rule: three copies of your data, on two different media types, with one stored offsite or in the cloud.
A backup you haven't tested is not a backup. Schedule a quarterly restore drill to confirm your backups actually work before you need them in a crisis.
Use a business-grade firewall and antivirus
Consumer-grade security software isn't built for business environments. Invest in business-grade endpoint protection that includes behavioural detection, not just signature-based antivirus. A next-gen firewall adds another critical layer of protection at your network perimeter.
Restrict access on a need-to-know basis
Not every employee needs access to every system. Apply the principle of least privilege — give each person only the access they need to do their job. This limits the damage if any single account is compromised.
Secure your Wi-Fi network
Use WPA3 encryption on your business Wi-Fi, change the default router password, and create a separate guest network for visitors and personal devices. Never allow unmanaged personal devices on the same network as your business systems.
Have a clear incident response plan
When — not if — a security incident occurs, the first 30 minutes are critical. Having a written plan of who to call, what to isolate, and how to communicate means you respond rather than panic. Make sure your team knows the plan before they need it.
Work with a managed IT partner who monitors 24/7
The best habits are automated and monitored. A managed IT provider watches your systems around the clock, patches vulnerabilities before they're exploited, and responds immediately when something goes wrong — so you don't have to.
"The cost of a cyberattack — in lost data, downtime, and reputational damage — is almost always far greater than the cost of prevention. Start with these ten habits and you'll be ahead of most small businesses."
Where to start
If you're not sure where your business stands on cybersecurity, start with a simple audit. Review your password policies, check which accounts have MFA enabled, and confirm your backups are working. If you'd like a professional assessment, our team offers a free security review for businesses of any size.
