Renewing your subscriptions annually to match your product lifecycle helps you better manage the security of your devices throughout their lifecycle. The security teams at AWS are continuously working to identify potential security vulnerabilities in FreeRTOS libraries, which helps you become aware of security issues timely and proactively plan for the deployment of patches. If there is a lapse in your subscription, you will incur a one-time fee and other costs that might affect your total cost of the subscription. See the pricing page for details.
