Small teams are rarely targeted because of who they are. They are often caught by the same everyday threats as everyone else, such as phishing emails, reused passwords and out-of-date software. A handful of consistent habits can reduce that risk considerably.
Use MFA and a password manager
Turn on multifactor authentication for email, cloud services and anything with administrative access. Encourage everyone to use a password manager so each account has a strong, unique password.
Keep devices and software up to date
Updates often fix security problems that are already known. Decide how operating systems, browsers and business applications will be updated, and who is responsible for checking that it happens.
Give people only the access they need
Not everyone needs access to every folder, system or admin setting. Granting access based on role limits the damage if an account is compromised, and makes leavers easier to deal with.
Back up data and test the restore
A backup you have never restored is an assumption, not a plan. Keep important data in more than one place, keep at least one copy separate from your main systems, and test restoring files from time to time.
Encrypt laptops and mobile devices
Disk encryption means a lost or stolen laptop is much less likely to expose company data. Check that it is switched on and that recovery keys are stored safely.
Prepare people for phishing
Most people will meet a suspicious email sooner or later. Explain what to look for, make it easy to report something odd, and make clear that nobody will be criticised for raising a concern.
Plan for lost devices and departures
Know in advance what you will do if a device is lost, and have a checklist for removing access when someone leaves.
Write down a simple incident plan
A short page covering who to contact, which accounts to secure first and who decides what to do next is far better than working it out under pressure.
