To set up a proxy detection api for security teams, route login IP addresses to an external scoring service. This service checks each IP against lists of known virtual private networks, open relays, and exit nodes. Teams often tie this check into their main login flow. If roles or permissions stay too broad after login, a passed IP check will not stop bad commands.

How to set up a proxy detection api for security teams

A network check starts when a user or app tries to log in. Your app reads the source IP address from the incoming network request. Next, the app sends that IP to the detection service over a secure web call. The service checks autonomous system numbers, datacenter ranges, and recent abuse reports. It then returns a risk score and flags any hidden routing layers.

Your login code reads this score before it grants a session. Low scores let the user log in right away. High scores can block the login or ask the user for a second factor. Teams also send these scores to their central log store. Analysts read those logs later to spot patterns across failed logins.

To keep logins fast, teams set a short timeout on the web call. If the external service responds too slowly, the app uses a local cache of recent IP scores. You must also protect the secret key that talks to the scoring service. Store that key in a secure secret store and give read rights to the login app role only.

What network IP checks solve and what they miss

Network IP scoring stops attackers who hide behind public relays or rented servers. It blocks automated credential stuffing before a bad actor reaches your login prompt. It also helps teams enforce geographic rules for staff and contractors. This setup works well as a first filter at the edge of your network.

Still, an IP check only looks at where a request comes from. It decides who logs in, not what queries or commands run during the session. An engineer on a clean home IP can still run a drop table statement by mistake. A stolen laptop on an approved office network passes every IP check without trouble. Also, an AI agent running inside your own cloud cluster always shows a trusted internal IP.

Once the login check passes, native network tools step out of the way. The user or script gets full use of whatever database role or server permissions they hold. If that role can read raw customer tables, every email, phone number, and card number is exposed. Network checks cannot rewrite query results or require a teammate to approve a risky command in flight.

How to pair IP checks with command controls

Strong security needs both edge network checks and runtime session rules. Start by keeping your IP scoring service at the login step to filter out bad traffic. Next, shrink the default roles that users receive after they log in. Remove standing admin rights from daily user accounts across your databases and cloud hosts.

Finally, add controls that inspect individual commands and queries after the session starts. Check every SQL statement or shell command before it reaches the database or server. Mask sensitive fields like national IDs and card numbers by rewriting matched fields in results. Ask a second team member to approve destructive actions before they run.

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 an IP detection service check during login?

The service checks the caller IP against lists of datacenter ranges, Tor nodes, and public relays. It also looks at routing records and recent abuse logs to calculate a risk score.

Can an IP check stop an insider from reading sensitive data?

No, an IP check only verifies the network location at login time. Once inside, a user can run any query allowed by their database role unless runtime controls inspect the session.

How do teams handle false positives from IP scoring tools?

Instead of blocking every flagged IP outright, teams ask the user for an extra login factor. They also keep an allowlist for known office networks and approved contractor address ranges.
