At ZKTeco USA, the security of our products is inseparable from the security we deliver to our customers. We maintain a coordinated vulnerability disclosure process for all ZKTeco USA hardware, firmware, software, and cloud services, and we publish security notices so that integrators, end users, and administrators can assess their exposure and act quickly. When a vulnerability is confirmed, our product security team works with the reporting party to validate the issue, determine its severity, develop and test a remediation, and release a fix or mitigation along with a public advisory. We welcome reports from security researchers, channel partners, and customers, and we ask that findings be shared with us privately first so that a fix can be made available before technical details are published. Every submission is acknowledged, tracked, and answered.
