You set up hcp boundary by linking your identity provider and deploying worker nodes. These workers route user traffic to private hosts without exposing the internal network. Most teams start by mapping identity groups to broad host catalogs. This approach gets engineers working fast, but broad roles soon create security risks. Once a session starts, an engineer with wide permissions can run any command.
How hcp boundary architecture works
The control plane runs as a cloud service that manages state and policies. You do not need to run or patch the main controller servers yourself. Instead, your team sets up scopes, roles, and host sets inside this cloud service. Users log in through your single sign-on tool to prove who they are. The service checks their role and lists the private hosts they can reach.
To reach private networks, you deploy lightweight workers inside your own cloud accounts. These workers dial out to the cloud service and wait for user sessions. When an engineer starts a session, traffic flows through the worker to the destination. This setup avoids opening inbound firewall ports on your private subnets. You can also chain workers together to reach deep network zones.
Admins group servers and databases into logical sets based on project or tier. A role binds an identity group to a specific set of hosts. When a team member leaves, removing them from the identity group revokes their role. This design replaces static network rules with identity checks at the start of each session.
What native session routing solves and what it misses
This native workflow solves the problem of managing complex network tunnels for remote teams. Engineers no longer need to share static network keys or manage local network files. Network teams can close public ports and keep private subnets hidden from the internet. Identity groups control who can open a tunnel to a given server or database.
Still, a network tunnel only checks identity when the session first starts. Once the tunnel is open, the routing layer treats the traffic as a raw stream. It cannot read individual database queries or check shell commands before they run. If an engineer logs into a production database, they have full role permissions.

This creates a gap between network routing and command-level safety during daily work. A tired engineer can still run a drop table statement over an authorized tunnel. They can also query tables that hold raw emails, phone numbers, or card numbers. The routing tool knows who opened the tunnel, but not what data returned.
Closing the command and data governance gap
Security teams need controls that inspect actions inside the session, not just the login. True safety requires checking each SQL statement or shell command before the server runs it. Teams also need data masking that rewrites matched fields like national IDs in query results. Pairing identity routing with statement-level checks gives teams full control over production work.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What is the difference between self-managed Boundary and the cloud version?
With the self-managed version, your team runs the controllers, database, and workers yourself. In the cloud version, the vendor runs the controllers and database for you. You only deploy workers inside your private networks to route internal traffic.
Do I still need a VPN when using identity-based session routing?
No, you do not need a traditional VPN for your engineering team. Workers route specific sessions to exact hosts without bridging the whole private network. Users only reach the single port and host allowed by their current role.
Does network session routing filter sensitive database results?
No, a network session router passes raw TCP traffic between the client and host. It does not parse database protocols to rewrite emails or card numbers in results. You need a dedicated inspection tool to mask sensitive fields during queries.
