Secure Your Network From the Application Level

Zero Trust Application Access or ZTAA is a security architecture that is designed to secure network infrastructure at the application level and grants access to applications based on pere-defined access policies.

ZTAA works on the principle of Zero Trust and least privilege where every user is validated and authenticated before being granted with least access privilege to the application through separate encrypted tunnels.

Secure Third-Party Access

Enabling secure access to third-party users like contractors and vendors, without causing data breaches has always been a tricky issue for organizations.

UTunnel’s Zero Trust Application Access solution facilitates secure access to the third party by granting least privileged access to specific applications and network resources on a need-to-know basis, thus reducing the chances of network exposure.

Data Security

UTunnel’s Zero Trust Application Access solution provides and limits access to applications based on the device’s security posture and risk value, thereby enabling secure, encrypted tunnels for each application connection.

ZTAA solutions provide one-touch secure access to SSH, RDP, HTTPS and HTTP servers and hosted applications while ensuring the sensitive data does not pass through unauthorized devices.

Secure Cloud Access

With organizations moving their resources to cloud platforms, providing secure access to cloud applications has become the biggest priority for organizations.

UTunnel’s ZTAA solution lets you secure your cloud-based resources and provides strictly controlled access to cloud-based applications from its user-intuitive web console. The console makes it easy to monitor user activity across the cloud network providing added visibility.

VPN Alternative

Zero Trust Application Access can be used as an alternative to conventional VPN as it enables secure access to specific applications based on granular access policies.

As ZTAA works on the principle of granting least privileged access to applications, it restricts lateral movement across the network, thus diminishing the chances of network infiltration. UTunnel’s ZTAA solution also mitigates issues with VPN such as disconnections from the client app side, thereby enhancing network performance.

ZTAA Frequently Asked Questions

Zero Trust Application Access is a cyber security technology based on Zero Trust architecture that secures an organization’s resource network at the application level by enabling secure access to employees as well as third-party users.
What is the difference between ZTAA and ZTNA?
Even though both Zero Trust Network Access and Zero Trust Application Access are based on the principles of Zero Trust architecture, both are sightly different from each other. Both terms are often used interchangeably. ZTNA applies Zero Trust technology at the network level to provide secure access to the corporate network. While ZTAA secures corporate networks at the application level and provides safe access to third-party users on a need-to-know basis.
Zero Trust Application Access is different from Virtual Private Network as ZTAA uses identity and policy based access control to authenticate users and grant limited access to selected applications on a network based on least access privilege. VPN on the other hand allows unrestricted access to the entire network to its users once they connect to the VPN network using client apps.
Zero Trust Application Access authenticates users using granular access policies as it believes that there is no implicit trust and grants the least privileged access to users on a need-to-know basis.
