OpenVPN Access Server is a self-hosted Zero Trust Network Access (ZTNA) solution you deploy into your own environment — on-prem or your AWS, Azure, or GCP account — so tunnel traffic and configuration never touch a third-party network. Access is enforced by application, not IP or subnet: each user reaches only the app they're entitled to, identified by domain name, with no visibility into anything else. That structurally blocks lateral movement — there's no connectivity path for a breach to exploit. With Access Server Link, deployment is a guided setup (hostname, cloud, region, password) with SSL certificates auto-provisioned and renewed, removing manual cert management as an attack surface. Entitlements tie to hostname, so they survive IP changes and autoscaling without rework. Your instance stays fully under your control, preserving the data ownership and audit posture required for HIPAA, SOC 2, and GDPR — full sovereignty over the control plane, with SaaS-level simplicity. The admin portal replaces SSH-based management: users, certificates, and access policies are configured through a browser, so shell access isn't required, shrinking your attack surface. The Zero Trust App Broker mediates every connection through a placeholder IP scoped to one authorized application — users never learn the real destination, so a compromised credential can't be used to probe or discover other systems. This enforces least privilege by design, not just by policy that can drift or be misconfigured. Client apps span Windows, macOS, iOS, Android, and Linux, so identity- and application-based controls apply consistently across devices. Deployment runs through preconfigured templates on AWS, Azure, and GCP, giving security teams repeatable, auditable rollouts.

AWS Directory Service for Microsoft Active Directory, commonly referred to as AWS Managed Microsoft Active Directory (AD), allows your directory-capable applications and AWS services to seamlessly utilize a managed version of Active Directory within AWS. This service is based on genuine Microsoft AD technology and eliminates the need for data synchronization or replication from your on-premises Active Directory to the cloud. Users can leverage standard Active Directory administrative tools and utilize inherent features like Group Policy and single sign-on. With AWS Managed Microsoft AD, integrating Amazon EC2 and Amazon RDS for SQL Server instances into your domain becomes straightforward, along with the ability to utilize AWS End User Computing (EUC) offerings such as Amazon WorkSpaces for AD users and groups. This service facilitates the migration of applications dependent on Active Directory and Windows-based workloads to the AWS environment. Additionally, AWS Managed Microsoft AD enables the application of Group Policies for managing EC2 instances while effectively supporting AD-dependent applications hosted in the AWS Cloud. Ultimately, this solution simplifies enterprise operations by providing a robust and scalable directory service in the cloud.

Active Directory serves as a centralized repository for information regarding various objects within a network, facilitating easy access and management for both administrators and users. It employs a structured data storage approach, which underpins a logical and hierarchical arrangement of directory information. This repository, referred to as the directory, holds details about various Active Directory entities, which commonly include shared resources like servers, volumes, printers, as well as user and computer accounts on the network. For a deeper understanding of the Active Directory data repository, one can refer to the section on Directory data store. Security measures are seamlessly integrated with Active Directory, encompassing logon authentication and the control of access to directory objects. Through a single network logon, administrators are empowered to oversee directory information and organizational structures across the entire network, while authorized users can readily access resources from any location within the network. Additionally, policy-based administration simplifies the management process, making it more efficient even for the most intricate network configurations. This framework not only enhances security but also streamlines resource management, making network operations more effective.

AWS Site-to-Site VPN is a comprehensive service designed to create secure links between your on-premises networks and AWS resources via IPsec tunnels. Each VPN connection is equipped with two tunnels that terminate in separate availability zones, enhancing the availability of your Virtual Private Cloud (VPC). In the event of a failure in one tunnel, the connection seamlessly switches to the alternate tunnel, ensuring uninterrupted access. For applications distributed globally, the enhanced Site-to-Site VPN feature offers superior performance by collaborating with AWS Global Accelerator, which intelligently directs your traffic to the nearest AWS network endpoint for optimal performance. Additionally, AWS Site-to-Site VPN accommodates both static and dynamic routing options, including BGP peering, allowing for greater flexibility in your routing setup. It also facilitates NAT traversal, enabling the use of private IP addresses within private networks that are behind routers utilizing a single public IP address. This versatility makes AWS Site-to-Site VPN a robust solution for diverse network configurations and requirements.

AWS Transit Gateway is a fully managed solution designed to link Amazon Virtual Private Clouds (VPCs) and on-premises networks via a central hub, which streamlines network design and removes the need for complicated peering setups. By functioning as a scalable cloud router, it ensures that each new connection is established only once, thereby improving efficiency. The service accommodates both dynamic and static layer 3 routing among VPCs and VPNs, using routing tables to determine the next hop based on the destination's IP address. Additionally, it allows for VPN connections between the Transit Gateway and local gateways, utilizing Equal Cost Multipath (ECMP) routing to optimize bandwidth by balancing traffic across multiple routes. Furthermore, AWS Transit Gateway Connect enhances this functionality by enabling seamless integration of Software-Defined Wide Area Network (SD-WAN) appliances within AWS through standard protocols such as GRE and BGP, which not only boosts bandwidth but also supports dynamic routing capabilities. This integration empowers businesses to modernize their network architecture while maintaining efficient and adaptable connectivity options.

Amazon Virtual Private Cloud (Amazon VPC) is a service that enables users to deploy AWS resources within a virtual network that they can configure to be logically isolated. This service offers users total authority over their networking environment, allowing them to select their own IP address range, establish subnets, and set up route tables and network gateways. Users can utilize both IPv4 and IPv6 for various resources within their virtual private cloud, which aids in providing secure and efficient access to applications and resources. As a core component of AWS, Amazon VPC simplifies the process of tailoring your network configuration to meet specific needs. You can design a public subnet for your web servers that require internet access while also enabling the placement of backend systems like databases or application servers in a private subnet that does not connect to the internet. Additionally, this flexibility allows organizations to enhance their security posture while optimizing resource management.

AWS VPN facilitates secure links between on-premises networks and AWS Virtual Private Clouds (VPCs) via IPsec VPN tunnels, ensuring a robust connection. Each VPN connection is designed with dual tunnels to enhance availability, terminating in distinct availability zones for added resilience. This service accommodates both static and dynamic routing through BGP, while also providing customizable options for tunnel configurations, such as inside tunnel IP addresses, pre-shared keys, and BGP Autonomous System Numbers (ASNs). The Accelerated Site-to-Site VPN option utilizes AWS Global Accelerator, optimizing traffic routing through the closest AWS edge location to decrease latency and jitter for an improved user experience. Additionally, AWS Client VPN is a fully managed and elastic VPN service, enabling users to securely connect to AWS and on-premises resources from anywhere using an OpenVPN-based client. This service supports various authentication methods, including Active Directory, mutual certificate authentication, and SAML-based federated authentication, ensuring flexibility and security for users. Ultimately, AWS's diverse VPN offerings cater to various connectivity needs while prioritizing security and performance.
