Proxy Detection API for Trust and Safety
You set up a proxy detection api for trust and safety by checking user IPs at login. Your app sends the client IP address to a threat scoring service and reads the risk response. Teams often grant the scoring worker broad database roles so it can write fraud flags to user tables. When those roles have too much power, one bad query can expose private customer records.

You set up a proxy detection api for trust and safety by checking user IPs at login. Your app sends the client IP address to a threat scoring service and reads the risk response. Teams often grant the scoring worker broad database roles so it can write fraud flags to user tables. When those roles have too much power, one bad query can expose private customer records.
How to set up a proxy detection api for trust and safety
First, your backend app captures the incoming IP address from the network request header. The app must parse the forwarding header carefully so attackers cannot spoof their true origin. Next, the backend worker sends that IP address to your chosen threat scoring service. This external service checks the IP against lists of known residential relays, VPN nodes, and Tor exit points.
The external service returns a simple payload with a risk score and network type flags. Your app reads these values and applies your internal fraud rules right away. High-risk scores can trigger a multi-factor challenge or block a payment before it runs. Low-risk scores let the user log in and use the app without extra friction.
Finally, your backend service writes the risk score and network flags into your main fraud database. Trust analysts later query these logs to spot attack patterns and tune their blocking rules.
Where native IP scoring roles fall short
A threat scoring workflow stops bad actors at the front door of your web app. It tells your login service whether an incoming network address looks safe or shady. Still, this check does not govern how your apps or analysts query the fraud database itself.
To investigate flagged accounts, trust and safety staff need direct database roles to read user history. Teams usually create a shared role with broad read permissions across user, payment, and log tables. Once an analyst logs in with that role, the database permits any read query they run.

Native database roles decide who can log in, not what each query does in flight. An analyst checking a suspicious IP also pulls raw emails, phone numbers, card numbers, and national IDs. If an attacker steals an analyst key, they can dump the entire user table in seconds. Masking rewrites matched fields in results so analysts can still do their jobs safely.
How to secure trust and safety data workflows
Start by separating the role that writes IP scores from the role that analysts use for reviews. The ingestion worker only needs permission to insert new rows into the fraud event table. It should never hold permission to read user profiles or update billing records.
For human reviewers, replace broad table grants with strict controls on every single query. Every query from a support tool or analyst laptop should link to an individual identity. You also need a way to inspect queries and mask sensitive columns before results return.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits beside the service as an open-source proxy, a sidecar for your database or API.
Before a query runs, hoop.dev guardrails check the statement against your rules. An AI Analyzer you configure can score intent or hold risky calls for human review. Next, hoop.dev data masking rewrites sensitive fields in responses, and each verdict is logged per listener. Explore the MIT-licensed project on GitHub.
Frequently asked questions
What network signals does a threat scoring service check?
These services check Autonomous System Numbers, datacenter ranges, Tor exit lists, and active residential relay nodes. They combine these signals to return a simple risk score for each login attempt.
Should our app block every user on a VPN?
No, because many normal users run VPNs for privacy on public Wi-Fi networks. Instead, use the score to require extra login verification or limit high-risk account changes.
How can trust analysts review fraud logs without seeing raw PII?
You can apply dynamic data masking to your database queries in flight. Masking rewrites matched fields like emails, phone numbers, and card numbers in query results.
