Granite Expands Granite Guardian Portfolio with Zero-Trust Cloud Security Services

Granite Telecommunications, a $1.65 billion provider of communications services to multilocation businesses and government agencies, announced the expansion of its Granite Guardian portfolio of managed network and security services to include Zero-Trust Cloud Security Services powered by Zscaler Inc.

Granite’s new service is made possible through a strategic partnership with cloud security leader Zscaler, which operates the Zero Trust Exchange, a cloud-native platform that leverages Secure Access Service Edge (SASE) to connect users, apps, and devices securely over any network, in any location.

Under the partnership, Granite will deliver Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA) standalone or in combination with Granite’s managed network services.

Granite Guardian’s Zero-Trust Cloud Security Services powered by Zscaler are ideal for businesses that have remote employees, multiple locations, use Microsoft 365 or other cloud apps. It’s also compelling for organizations migrating applications to the cloud, planning a merger or acquisition, or finding security to be unmanageable. In addition, Zscaler ZIA and ZPA are FedRAMP certified, so they are a good fit for government agencies.

ZIA, a secure Internet and Web Gateway delivered as a service, includes:

  • Cloud Firewall/Intrusion Protection Service (IPS)
  • Sandboxing
  • URL Filtering
  • Data Loss Protection (DLP)
  • Cloud Access Security Broker (CASB)
  • Browser Isolation
  • Cloud Security Posture Management (CSPM)

ZPA, a distributed cloud service that provides fast and secure access to private applications running on-premises or in the public cloud, includes:

  • Multifactor Authentication
  • Granular Application Access Control
  • Application Micro-segmentation
  • Application and Server Discovery
  • Cloud Availability and Automatic Failover
  • Device Posture Check
