Website security checklist for small businesses
Start with a business inventory
List your main website, customer portal, public API and file-sharing endpoints. Record an owner and the purpose of each service. A marketing page and a customer document portal need different questions, even when they use the same hosting provider.
Define a useful first assessment
Ask which assets and user roles are included, which actions are excluded and what evidence you will receive. OWASP WSTG provides a structured testing reference; using its name alone does not establish the coverage of a particular engagement.
Turn findings into work
Arrange a short handover with the person who maintains the site. For each accepted finding, record an owner, a target date and a way to verify the fix. Keep unknown or untested areas visible rather than calling them safe.
Practical checklist
- Name each public service and its owner.
- Separate production from staging.
- Agree authorization and limits before testing.
- Reserve time for fixes and retesting.
A common question
Does a clean scan mean the website is secure?
No. A result describes the checks performed within a particular scope and time. It is not proof that every vulnerability is absent.
