Security and privacy are deeply rooted in the foundations of the Graphene operating system. Completely de-googled and de-bloated, Graphene takes advantage of all existing android security features with numerous additions on top. Disk encryption, clipboard security, hardware identifier protection, IOMMU baseband isolation, and a system integrated firewall with custom rulings keep Graphene protected from adversaries.
