Airports and Standard Gauge Railway (SGR) stations in Kenya employ multiple security checkpoints as a strategic safety measure to enhance passenger and infrastructure protection.

• The layered security system applies the principle of 'defense in depth,' ensuring that even if one checkpoint misses a threat, subsequent layers can intercept it.
• Multiple agencies, including airport police, private security firms, and transport authorities, often share responsibilities across different screening stages.
• These checkpoints are designed not only to detect prohibited items and weapons but also to manage crowd flow and maintain order in high-traffic environments, adhering to global aviation and rail security standards.
