Fortanix is bringing hardware security technology to database search with Confidential Data Search, with the goal to help organizations process highly sensitive data in databases. Fortanix’s technology uses confidential computing technologies to allow data to be searched within the hardware vault.
There are various encryption schemes and technologies to protect data while at rest and while being transported between systems. Confidential computing provides layers of hardware protection so that data remains secure even while it is being processed. Data is stored in a secure hardware vault; authorized parties need a code to unlock the vault; and the data is processed inside without ever leaving the vault.
Advancements in chip technology have made it possible to build these secure vaults directly inside chips. The chip makers have also baked in hardware mechanisms called attestation that ensures only authorized parties can access data in secure vaults.
