A hybrid mesh firewall (HMF) is a multideployment mode firewall, including hardware, virtual appliance and cloud-based options, with a unified cloud-based management plane. HMF’s are designed to support hybrid environments and evolving use cases by offering mature continuous integration/continuous delivery (CI/CD) pipeline integration, native cloud integration, and advanced threat prevention capabilities extending to Internet of Things (IoT) devices and DNS-based attacks. With the adoption of hybrid environments, clients prefer the same firewall vendor with centralized management and visibility of firewall policies across environments to ease administration and reduce operational complexity. As a result, the demand and adoption of cloud firewalls from the same on-premises firewall vendor is growing. Hybrid mesh firewalls support this use case through hardware, virtual and dedicated cloud firewall deployment types, along with cloud-based centralized visibility and management capability.
Secure access service edge (SASE) platforms deliver converged network and security-as-a-service capabilities, such as software-defined WAN (SD-WAN) and secure access to the web, cloud services and private applications regardless of the user’s location, the device used or where that application is hosted. These offerings primarily use a cloud-centric architecture delivered as a platform by one vendor. SASE securely connects users and devices with applications, services and other users. It supports branch office and remote worker connectivity and on-premises general internet security, private application access and public cloud service provider access use cases.
Gartner defines software-defined WAN (SD-WAN) as products used to connect branch locations to other enterprise and cloud locations. SD-WAN products provide dynamic path selection based on business or application policy, routing, centralized orchestration of policy and management of appliances, virtual private network (VPN) and zero-touch configuration. SD-WAN products are WAN transport/carrier-agnostic and create secure paths across physical WAN connections.
Gartner defines security service edge (SSE) as an offering that secures access to the web, cloud services and private applications regardless of the location of the user, the device they are using or where that application is hosted. SSE protects users from malicious and inappropriate content on the web and provides enhanced security and visibility for the SaaS and private applications accessed by end users. Security service edge provides a primarily cloud-delivered solution to control access from end users and devices to applications, as well as websites and the internet. It provides a range of security capabilities, including adaptive access based on identity and context, malware protection, data security and threat prevention, as well as the associated analytics and visibility. It enables more direct connectivity for hybrid users by reducing latency and providing the potential for improved user experience. Capabilities that are integrated across multiple traffic types and destinations allow a more seamless experience for both users and administrators while maintaining a consistent security stance.
