The Falcon Flex for Services covers incident response, proactive security services, advisory, platform services, and training. Additionally, CrowdStrike is introducing the Zero Dollar Flex Fund, providing qualifying new services customers with access to 200 hours of CrowdStrike Services at no initiation cost, including 160 hours of incident response and 40 hours of proactive services. This initiative aims to lower the barrier for organizations to engage with CrowdStrike\u0026rsquo;s expertise, especially those seeking expert support before committing to a broader platform.
