Seven security mistakes small teams can avoid

Accounts and access

Three recurring mistakes are password reuse, missing MFA and permissions that outlive a person’s role. Assign an owner to access changes. Review important accounts, close unused access through an approved process and separate administrative work from everyday accounts.

Devices, messages and recovery

Unpatched systems, unverified payment requests and backups that have never been restored are three more common gaps. A seventh is not knowing who to contact during an incident. These weaknesses reinforce each other: a compromised account can reach a poorly protected backup, and a delayed report can increase damage.

Make improvements measurable

Choose one owner and a realistic completion date for each change. Evidence should be concrete: a tested restore, a reviewed access list or a documented callback process. Buying a tool without assigning responsibility rarely fixes a process gap.

Common mistakes

• Buying tools before assigning ownership
• Treating an untested backup as recovery
• Leaving former-role access in place
