The OWASP Top 10, Explained for Business Leaders

The OWASP Top 10 gives business and engineering teams a shared starting point for discussing application risk. It does not replace a test plan tailored to your application.

What it is

An awareness resource covering important web application risk categories, maintained by the Open Worldwide Application Security Project. It is not a compliance standard, a complete testing checklist, or a security guarantee.

Four risks to discuss with your team

These are selected examples, not the complete category list or a claim about their prevalence in your environment. Use the current OWASP edition when agreeing assessment coverage.

• Broken access control — users reading or changing another user's or tenant's data without authorization.
• Injection — untrusted input being interpreted as instructions by a query engine, interpreter or other component.
• Security misconfiguration — unsafe defaults, unnecessary exposure or errors that disclose internal details.
• Software dependencies and supply chains — third-party components and their build or delivery paths require inventory, integrity controls and risk review.

Three questions to ask your team

• "When did we last test access control across user roles and tenants — manually, not with a scanner?"
• "How do we know which of our dependencies have known vulnerabilities right now?"
• "If a tester chained two medium findings into account takeover, would our monitoring notice?"

An agreed assessment can investigate these questions using selected OWASP guidance and application-specific tests. Confirm which questions, roles, systems and monitoring checks are in scope; a Top 10 label alone does not establish coverage.
