Azure Bastion: Secure Remote Access to Your Virtual Machines
Azure Bastion is a fully managed platform service from Microsoft that delivers secure, browser-based RDP and SSH access to your Azure virtual machines - without exposing those machines through public IP addresses. For enterprise IT teams managing hybrid or cloud-native environments, Azure Bastion removes a critical attack surface while simplifying remote administration at scale.
TechPower helps organisations deploy and optimise Azure Bastion as part of a broader Azure security strategy, ensuring your remote access infrastructure is hardened, compliant, and cost-effective from day one.

Overview: Why Azure Bastion Matters
Traditional approaches to secure VM access - such as manually deployed jump box servers or bastion hosts - require significant overhead to configure, maintain, and patch. Azure Bastion replaces that complexity with a managed service that provisions directly within your Azure virtual network.
Key advantages at a glance:
- No public IP addresses required on your virtual machines
- RDP and SSH sessions delivered securely over TLS on port 443
- Access managed through the Azure portal or native clients - no third-party tools needed
- Protection against common threats including port scanning and lateral movement
- Single hardened access point covering all VMs across local and peered virtual networks
For IT decision-makers, this translates to reduced operational burden, a smaller attack surface, and stronger alignment with zero-trust security principles.

Key Capabilities
Agentless, Browser-Based Connectivity
Azure Bastion requires no agent installation on your VMs or end-user devices. Sessions are initiated directly through the Azure portal using supported browsers, making secure access available from virtually any device or location without software dependencies.
Scalable SKU Tiers for Every Organisation
Azure Bastion is available in four tiers to match your operational scale and compliance requirements:
- Developer - A free, lightweight option for individual developers and testers connecting to a single VM at a time
- Basic - Core RDP and SSH access for smaller deployments with straightforward requirements
- Standard - Supports a higher volume of concurrent connections, suitable for enterprise teams managing multiple VMs simultaneously
- Premium - Designed for highly regulated environments, with advanced session management features including graphical session recording and private-only deployment options
Session Recording (Premium)
Azure Bastion Premium introduces VM session recording, allowing administrators to capture, store, and review RDP sessions for audit and compliance purposes. This is particularly valuable for organisations subject to regulatory frameworks that require audit trails of privileged access activity.
Private-Only Deployment (Premium)
For organisations with strict network isolation requirements, the Premium SKU supports connecting to Azure Bastion via a private endpoint rather than a public one. This enables full remote access management without any dependency on public internet routing.
Automated Network Access Control
On deployment, Azure Bastion automatically configures network access control lists (ACLs) across your subnets, reducing the manual configuration burden and ensuring consistent policy enforcement across your virtual network.

Use Cases
Enterprise VM Administration
Large IT teams managing dozens or hundreds of Azure VMs benefit from a centralised, auditable access layer. Azure Bastion consolidates remote access through a single, governed channel rather than individual, unmanaged connections.
Regulated Industries and Compliance-Driven Environments
Financial services, healthcare, and public sector organisations with strict access logging requirements can leverage Azure Bastion Premium's session recording and private endpoint features to meet compliance mandates without building custom solutions.
Developer and DevOps Teams
Development teams that need frequent, fast access to Azure VMs during build and test cycles can use the Developer tier for frictionless, secure connectivity - without waiting on IT to provision jump hosts or manage VPN configurations.
Zero Trust Network Architecture
Azure Bastion is a natural fit for organisations adopting a zero-trust security model. By eliminating public IP exposure on VMs and enforcing access through a managed, identity-aware gateway, it supports the principle of least-privilege access at the infrastructure level.

Pricing
Azure Bastion is billed on a per-hour basis, with additional charges for outbound data transfers depending on the SKU in use. For most organisations, this is significantly more cost-effective than the staff time and infrastructure overhead associated with self-managed jump servers.
TechPower can provide a detailed cost comparison based on your current environment and Azure consumption profile.
