To implement step up authentication based on ip risk, check the source IP during login. Prompt the user for a second factor when the IP looks risky. Teams set up this check inside their identity provider. This stops bad logins from unknown networks. Still, wide roles still give full database and server control after login.
How to implement step up authentication based on ip risk
Your login system reads the client IP address when a user starts a session. It compares that address against a list of trusted office networks and VPN ranges. It also checks threat feeds for known proxy servers, botnets, and hosting providers.
If the IP matches a safe office range, the user logs in with normal credentials. If the IP comes from an unknown network, the system raises the risk score. A high score triggers a step-up rule right away.
The rule forces the user to pass a second check before entering the app. The user must tap a push prompt or use a hardware security key. Once the user passes that check, the identity system grants a session token.
Teams also check for sudden travel between two distant places. If a user logs in from two countries in ten minutes, the risk score spikes. The system blocks the login or asks for a phishing-resistant hardware key.
How to tune IP risk rules for engineering teams
Start by listing all static IP ranges that belong to your company. Add your corporate VPN exit nodes and office gateways to a safe list. Next, pick a threat feed that flags public proxies and bad actors.
Set up your login rules in report-only mode first. Watch the logs for a week to spot false alarms from home networks. Engineers who travel or use mobile hotspots often trigger high risk scores.

Pair IP checks with device trust checks to reduce noise for remote staff. A known laptop on a hotel network can get a lower risk score. An unknown device on that same hotel network should always trigger a step-up prompt. After you tune the rules, turn on active prompts for all production systems.
What IP risk checks solve and what they leave open
IP risk checks do a great job at the front door. Stolen passwords fail when an attacker tries them from a strange network. This blocks credential stuffing and basic automated attacks before they start.
Still, login checks only decide who gets into the system at the start. They do not watch or control what happens inside an active session. Once an engineer passes the step-up prompt, their role defines their power.
If that role has broad write rights, the user can run any query or command. A careless script can drop a table or read thousands of customer rows. A compromised laptop on a safe office IP also bypasses the network check.
Network rules cannot inspect individual SQL statements or CLI commands in flight. They also cannot mask sensitive fields like emails, phone numbers, or card numbers in query results. Teams still need controls that check every command and rewrite sensitive data during the session.
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 triggers an IP risk step-up prompt?
Unknown IP ranges, public proxies, Tor exit nodes, and fast travel between countries trigger a prompt. The identity system sees the high risk score and asks for a second factor.
How do VPNs affect IP risk checks?
Corporate VPNs use known IP ranges that admins mark as safe in the login tool. Consumer VPNs share IPs across many users and often trigger a high risk score.
Does step-up auth protect databases after login?
No, step-up checks only verify the user when the session starts. Once logged in, the user can still run risky queries or pull raw data like national IDs.
