Cloud security vendor Fortanix has updated its Data Security Manager to incorporate support for AWS\u2019 external encryption key store system, adding another major public cloud vendor to the list of those supported for the company\u2019s key management system.With this week's update, Fortanix, which already supports this type of cloud key management system in Azure and Google Cloud, is trying to solve one of the major security and regulatory problems posed by multicloud environments. Every public cloud provider has its own management service for digital keys, which generally don\u2019t integrate with services provided by other vendors. That\u2019s a serious headache for companies whose IT departments use products hosted in different clouds.Using Fortanix\u2019s system, however, users can segregate keys from operational workloads being run in AWS, which solves regulatory problems posed by GDPR and other data protection requirements, as well as offering an additional buffer of security between a workload\u2014which could be compromised\u2014and the security keys needed to access related data.\u201cBy using Fortanix DSM as a centralized, external key store, customers maintain full custody of their keys with complete control over the data encryption policies on AWS or other cloud providers,\u201d the company explained in a statement. \u201cThis control includes defining where the keys reside, access, and policy control.\u201dKey management and multicloud security is messy, according to Gartner senior director analyst Brian Lowans. It\u2019s a mixed world, in terms of what different cloud and security vendors need to provide in order to offer reasonable security, which sometimes doesn\u2019t always match up with what they actually do offer.\u201cThe detail gets messier as you go into it,\u201d he said. \u201cThe approach by the cloud service providers like AWS so far is that they\u2019ve been very helpful in creating their own key management service, so they have leveraged a particular hardware security module and use that to create the key management service that\u2019s then offered to customers.\u201dWhat Fortanix has done, however, offers an independent, integrated option for the multicloud users of the world, letting them leverage their own technology to provide key management as a service.\u201cThat means they can help customers [utilize] key management systems in their own network \u2026 as well as help customers deliver and use [key management systems] across a variety of cloud service providers,\u201d said Lowans.
