ZTNA is an acronym for Zero Trust Network Access. It’s a security strategy built on the principle of least privilege, which means that users are only given the bare minimum permissions they need to do their job – no more, no less.
This approach starkly contrasts traditional security models, which usually rely on perimeter defenses on the premise that blanket access is naturally granted to everyone inside the organization. With ZTNA, there are ZERO trusted insiders or untrusted outsiders – everyone is treated equally, with zero trust.
SASE is short for Secure Access Service Edge. It’s a cloud-based security architecture that enables the convergence of network and security functions into a single, integrated, fully comprehensive platform.
SASE provides secure access to data and applications from any location, on any device, and is fully scalable. In contrast to more traditional security methods, SASE provides a more holistic approach that considers both the network and the security needs of an organization.
Zero trust network architecture (ZTNA) and secure access service edge (SASE) are two terms often used interchangeably, but there is a big difference between the two.
SASE is a comprehensive, multi-faceted security framework, while ZTNA is a more focused security model that limits resource access and is a part of SASE.
ZTNA is a security model that does not require users to have a legacy VPN (Virtual Private Network) to access internal resources and instead relies on authentication and authorization methods such as multi-factor authentication (MFA) to verify users.
SASE applies a more holistic approach to security that includes both network and security functions in one platform. The SASE platform can be delivered as a cloud service or as an on-premises application.
It’s worth noting that ZTNA must run with SASE for optimal security, and here are a few reasons why.
There are many advantages of combining SASE and Zero Trust Network Access. First, the combination allows organizations to move away from the traditional network perimeter model and adopt a more modern, cloud-centric approach. This provides greater security as well as greater flexibility and scalability.
Additionally, by leveraging the strengths of both SASE and Zero Trust Network Access together, businesses can reduce costs associated with managing multiple security solutions and better optimize the security and protection of their data and applications from external threats with not one but two state-of-the-art security systems.
Here’s a quick list of the top eight reasons to combine ZTNA with SASE:
Perimeter 81’s fully comprehensive SASE solution revolutionizes how companies secure their data, resources, and users within their network. The company’s Secure Access Service Edge platform combines network and security functionality into a single scalable, cost-efficient, and cloud-based service to provide best-in-class SASE security.
We provide an easy-to-use and robust cloud-based networking and network security platform that connects all users, in the office or remote, to all corporate resources, whether they are in the cloud or on-prem. It employs identity-driven access control to ensure that users only have access to the resources they need to do their job and nothing more.
Enforcing access with a least-privileged strategy and strictly enforced access control, organizations implementing Perimeter81’s SASE can control interactions with resources based on relevant attributes, including application type, user and group identity, and the sensitivity of the data being accessed.
Additionally, enabling security AND visibility for cloud services and on-prem resources, Perimeter81’s SASE architecture enables businesses to take advantage of key cloud capabilities for an agile, holistic, adaptive, self-updating security posture. This empowers organizations with an efficient and easily adaptable tool for their business needs, no matter where they are located.
Perimeter81’s SASE solution creates a single network for the entire organization’s resources — data centers, branch offices, cloud resources, and mobile and remote users. It also enables fast connection speeds for all workers, whether in the office or remotely, delivering a low-latency service to users across all enterprise edges.
Perimeter81 enables the core benefits, including:
So, with Perimeter81’s SASE solution, when users are connected, they’re protected.
