Insyde believes that current customer platforms are following our guidelines for protecting sensitive system variables from malicious changes. As the first BIOS vendor to ship production systems supporting the UEFI standards, Insyde has always worked to improve the UEFI standards and our InsydeH2O BIOS. Our customers are encouraged to work with their Insyde contacts to continue to build secure systems.”
