Platform economics is the pricing and incentive structure a digital platform imposes on users, developers, or service providers. It includes fees, commissions, ranking rules, access limits, revenue shares, and other conditions that shape how people use the platform and how much value the platform captures from them. In practice, this can affect app stores, cloud marketplaces, identity systems, and online ad ecosystems.
In cyber security, platform economics matters because incentives influence behavior. A costly or restrictive model can push developers to delay updates, reduce security spending, or seek unofficial distribution paths that are harder to control. Attackers also exploit platform incentives by abusing free tiers, referral rewards, affiliate programs, or marketplace visibility rules to scale fraud and malware. Defenders study platform economics to understand where abuse is financially attractive and to design controls that change the attacker’s payoff, such as rate limits, verification, chargeback controls, and abuse-resistant billing rules.
