Nac Support
To set up nac support, link your network switches to a central rule server. This system checks every device before it lets traffic onto your local network. Most teams start by grouping devices into simple trust zones. They assign broad network roles based on user groups or machine types. When these roles are too wide, any valid device can reach sensitive servers. A laptop that passes the first check can then talk to production databases.

To set up nac support, link your network switches to a central rule server. This system checks every device before it lets traffic onto your local network. Most teams start by grouping devices into simple trust zones. They assign broad network roles based on user groups or machine types. When these roles are too wide, any valid device can reach sensitive servers. A laptop that passes the first check can then talk to production databases.
How nac support works on your network
Network access control starts the moment a device plugs in or joins Wi-Fi. The switch or wireless point pauses traffic and asks the device for proof. The device sends its user key or machine certificate to the central server. Next, the server checks this proof against your team directory and health rules. It checks if the laptop has an active firewall and updated security tools.
If the device passes these checks, the server sends a message back. The switch then opens the port and assigns the device to a network segment. If the device fails, the switch moves it to a guest zone. This setup keeps unknown machines off your core network wires and wireless zones. Admins manage these rules in one place and push updates to all switches.
How to plan your device check rules
Good device rules start with a clear map of your machines and users. Teams first run their network checks in listen mode to watch all traffic. This step shows which printers, laptops, and servers plug into each wall port. If you turn on strict blocks too soon, you might lock out key apps. Once you know every device type, you can write simple check rules.
Most teams use machine keys for company laptops and MAC rules for printers. When a device changes its state, the network controller drops its current link. The machine must then pass the health check again to rejoin the network. Teams also set up fallback rules in case the main rule server goes offline. This planning keeps daily work moving while blocking stray devices at the edge.

What network checks solve and what they miss
Native network checks do a great job of blocking rogue laptops at the door. They make sure only company machines and known users get an IP address. They also stop infected laptops from joining the office network until they update. Still, network checks only decide who gets onto the wire at login time. Once a device is on the network, the switch does not read app commands.
A valid user on a healthy laptop can still run risky database queries. Network segments cannot tell a safe read query from a command that drops tables. They also cannot rewrite sensitive fields like emails, phone numbers, or card numbers. The network layer sees packets and ports, not SQL statements or shell commands. To control what users do inside databases and servers, teams need deeper checks.
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 does nac support do when a device fails a check?
When a device fails a check, the switch blocks it from internal servers. Most setups move the machine to a safe zone so it can download updates.
Does network access control inspect database queries or shell commands?
No, network controls only check devices and users when they join the network. They do not read or block individual queries or commands sent inside a session.
How do teams roll out network checks without breaking daily work?
Teams turn on monitor mode first to log all connected devices without blocking them. After fixing any missing device keys, they turn on active blocks one group at a time.
