You test new login rules using conditional access report only mode microsoft entra id. This setting logs policy results during sign-in without blocking users or prompting them. Security teams use this mode to check rule impact before turning rules on. Without careful checks, broad roles and rules can lock admins out or leave gaps. Testing rules first helps teams spot mistakes early.

How conditional access report only mode microsoft entra id works

When a user logs in, the directory checks every active and report-only rule. In report-only mode, the system evaluates the user, device, location, and target app. It then writes the result to the sign-in log. The user does not see any extra prompts or blocks from that test rule. Admins read these sign-in logs to see which rules would pass or fail. A log entry shows if the rule would require multi-factor checks or block sign-in. Teams filter these logs by user, app, or rule name to find false positives. Once the team trusts the log data, they switch the rule to active status. This workflow stops sudden lockouts across the company during policy rollouts.

Reading sign-in logs and rule results

Sign-in logs record the outcome of each report-only rule during every login event. The log marks whether a rule matched the user and what action would happen. Some rules need user interaction, like a multi-factor prompt, so logs mark those as needed. Other rules do not apply to the login event, and the log notes that too. Admins review these entries over several days to catch rare login patterns. Service accounts and background scripts often show up during this review period. If a rule would break a script, the team adjusts the rule scope first. This log review makes policy rollout safe for daily work.

What directory login rules solve and what they miss

Directory rules do a great job of checking who can log into an app. They check identity signals like network location, device status, and user group membership. Report-only mode lets teams test these login checks safely before enforcing them. Still, directory rules only act at the moment a user signs in. Once the login succeeds, the directory policy has finished its job. It cannot see what happens inside a database session or a server shell. A user who passes the login check might still hold broad database permissions. They can run a bad query or read raw emails, phone numbers, and card numbers. Directory rules also do not mask national IDs in query results or approve single commands. Teams need controls that inspect and govern actions inside the session itself.

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

Does report-only mode prompt users for multi-factor checks?

No, report-only mode never interrupts the user or asks for extra login steps. It only writes the expected result into the directory sign-in log for review.

How long should a team keep a rule in report-only mode?

Most teams run a rule in report-only mode for one to two weeks. This window captures normal workdays and weekly batch jobs in the sign-in logs.

Does report-only mode control what queries a developer runs after login?

No, directory rules only check the sign-in event at the start of a session. They do not inspect database queries, shell commands, or data returned during the session.
