Aryaka’s Private Access solution is a highly flexible, fully managed virtual private network solution. It leverages Aryaka’s global HyperScale PoPs architecture for unified connectivity and management for users anywhere to on-premise and cloud resources. Additionally, Aryaka Private Access users can leverage the full capabilities of Aryaka Unified SASE with the integration of our Next Generation Firewall/Secure Web Gateway (NGFW-SWG) for expanded web traffic and application inspection and security.

SmartSecure Private Access is based on the Enterprise VPN solution by NCP Engineering, a leading VPN provider.

SmartSecure Private Access consists of the following architectural elements:

SmartSecure Private Access Clients

The SmartSecure Private Access solution provides a centrally managed client suite for all major desktop or mobile operating system, including:

Aryaka’s SmartSecure Private Access Clients allow end user devices to select the closest Aryaka PoP for optimal, high-performance network access and reach it with the most effective tunneling protocol.
The SmartSecure Private Access Client ensures robust, unified endpoint compliance. It protects the integrity of the enterprise network by strict VPN access control, which first terminates on the nearest Aryaka SmartSecure Private Access Node and then proceeds to the appropriate private or public DC destination. Traffic travels over the Aryaka FlexCore, delivering the performance benefits of Aryaka’s Layer 2 and Layer 3 core network. Zero Trust capabilities are also supported.
The SmartSecure Private Access Client is a communication software product for universal implementation in any remote access VPN environment. It allows remote workers to access applications and data transparently and securely, on-premise or in the cloud, from any location – just as if they were in the corporate office. Seamless roaming provides an optional secure, always-on connection to the corporate network, automatically selecting the fastest medium for access to the internet. When the access point or the IP address changes, Wi-Fi roaming, or IPsec roaming maintains the VPN connection. Even behind firewalls whose settings always block IPsec data connections, the Private Access Client ensures remote access is available by finding an unlocked path. The client supports domain logon using a credential service provider after establishing a VPN connection to the company network.
A bypass function in the Private Access Client allows the IT administrator to configure the client so that certain applications are exempted from the VPN and the data is sent over the internet even when split tunneling is disabled. This prevents applications such as video streaming from unnecessarily taxing the enterprise infrastructure.
All client configurations can be locked by the administrator, meaning that the user cannot change the locked configurations.
The Private Access Client is simple to install and simple to operate. A graphical, intuitive user interface provides information on all connection and security states. Moreover, detailed log information supports effective assistance from the help desk.

SmartSecure Private Access Node

Aryaka’s Private Access Clients connect to the Aryaka Private Access Node closest to them. Aryaka’s Private Access Node are a virtual service hosted on Aryaka’s global HyperScale PoPs, which provide a sub-30ms onramp to the Aryaka Core Network to 95% of knowledge workers around the planet. Aryaka’s HyperScale PoPs host services that go beyond basic network connectivity: network and application acceleration, strict separation of customer-dedicated resources and secure traffic encryption, among others. Web and application security capabilities are also strengthened with the combination of Private Access and Aryaka NextGen Firewall and Secure Web Gateway.

After secure connections are established, the Secure Private Access Node function receives traffic from all the clients accessing it, and routes it across the high performance Global Aryaka FlexCore network to either the enterprise HQ/DC or to a SmartCloud service location that peers optimally given the user’s location.

SmartSecure Private Access Node are based on a multi-tenant architecture and a hardened Linux operating system which is optimized for maximum security. Furthermore, the Aryaka HyperScale PoP architecture guarantees deterministic performance and high availability.

SmartSecure Private Access Node can handle a highly scalable number of connections to the company network via an IPsec VPN. The Private Access Clients users can be assigned the same private IP address from a pool assigned by the company each time they connect to the network. This makes remote administration much easier as each user can be identified by their IP address. If the IP address is assigned dynamically from a pool, it will be reserved for the user for a defined period (lease time). Dynamic DNS (DynDNS) ensures that the VPN Gateway is still reachable if the device is assigned a dynamic IP address.

SmartSecure Private Access Manager

The SmartSecure Private Access Manager provides the configuration and management function for all components in the Aryaka Private Access solution. Together with the Private Access Node, it is also tasked with user authentication via communication with enterprises’ existing IAM (Identity & Access Management) systems.

The SmartSecure’s Private Access Manager allows Aryaka to provision and manage Private Access Clients and Private Access Node in the PoPs. It also establishes the connectivity with enterprises’ over-arching IAM systems for the authentication of Private Access Clients. With this mechanism, the security status of mobile and stationary end devices is verified prior to the device gaining access to the corporate network. All parameters are defined centrally by Aryaka on behalf of the enterprise, and remote workers are granted access rights based on their compliance to them.

SmartSecure Private Access Manager is a key component in providing a VPN solution that is easy to establish and operate.

The Private Access Manager integrates with an enterprise’s existing identity management (e.g. Microsoft Active Directory) and requests regular updates. As soon as a new employee is listed in this database, the Private Access Manager creates an individual configuration for this user, according to defined templates. If a former employee has been removed from the database, the Private Access Manager immediately blocks this VPN access. This eliminates the need to manually configure the computers of all mobile employees. The Private Access Manager also enables fast rollout of many users and software certificates.

Private Access Manager provides the following functions:

Client Configuration

Private Access Manager provides the configuration and management of all components for the Aryaka Private Access solution. This includes the Private Access Clients for Windows, macOS, iOS and Android. All relevant parameters are predefined and stored in templates.

Automatic Update Process

The fully automatic update process allows the administrator to centrally provide all remote Private Access Clients with configuration and certificate updates. As soon as the client logs in to the corporate network, the system automatically updates the client. If malfunctions occur during the transmission, then the previously existing configuration remains unaffected.

License Management
(Used only by Aryaka Operators)

The licenses of all connected components are centrally stored in the PAM and managed by Aryaka for enterprise customers. The system transfers them into a license pool and automatically manages them according to specified guidelines. This license transfer might be used for: transfer into a configuration per remote client or gateway, returning the license to the license pool when an employee leaves a company, or triggering a prompt when no more licenses are available.

System Monitor
(Used by Aryaka Operators)

Aryaka can offer enterprises immediate insight into all important events within the SmartSecure Private Access solution. The administrator can use the system monitor as needed to call up status information in real-time, or to access previously saved data respositories for the remote access environment.
