# Contractor Access in 60 Minutes Using Entra Conditional Access

Contractors keep work moving, but their access often becomes a long-term risk.

One project ends, another begins, and suddenly you have accounts that still exist, permissions that never got removed, and a “we’ll clean it up later” list that never shrinks.

This is how ghost accounts happen. Not through bad intent, but through busy calendars.

The goal is simple: **grant access quickly, limit it tightly, and revoke it automatically.** With Entra Conditional Access, you can build a “self-cleaning” contractor access process in about an hour.

## The Financial and Compliance Case for Automated Revocation

Manual offboarding depends on memory, and memory is not a security control.

Dormant contractor accounts are valuable targets because they often:

- Go unnoticed
- Keep permissions longer than needed
- Are not monitored like active staff accounts

A well-known retail breach from the last decade started with third-party credentials and expanded because vendor access was broader than necessary. The lesson still applies: contractor access must be **least privilege**, time-bound, and easy to shut off immediately.

Automated revocation reduces your attack surface and supports audit readiness by showing consistent access controls and enforcement.

## Step 1: Create a Dedicated Contractor Security Group

Instead of managing contractors one-off, centralize control.

Create a group such as:

- External-Contractors
- Temp-Access
- Project-Vendors

This group becomes your on/off switch:

- Add contractor when they start
- Remove contractor when they finish

Everything else becomes policy-driven and repeatable.

## Step 2: Require Strong Sign-In Controls for Contractors

Create a Conditional Access policy assigned to your contractor group and require:

- Multi-Factor Authentication (MFA)
- Risk-appropriate sign-in controls (based on your environment)

This prevents a simple password compromise from becoming a full-access incident.

## Step 3: Set a Session Control That Forces Re-Authentication

Contractors should not have open-ended access.

In your policy, configure a **sign-in frequency** aligned to contract duration or project needs. The practical value is big:

- If a contractor is removed from the group, they cannot continue authenticating
- Sessions do not live forever
- “Forgotten access” becomes harder to exploit

This is how you stop access from lingering quietly in the background.

## Step 4: Limit Contractors to Only the Apps They Need

A contractor does not need your entire ecosystem.

Create a second Conditional Access policy for the contractor group:

- Allow only approved applications required for their role
- Block everything else by default

This keeps their access narrow and dramatically reduces blast radius if credentials are misused.

## Step 5: Add Extra Proof When It Matters Most

If your environment supports it, layer stronger requirements for higher-risk activity, such as:

- More secure authentication methods
- Device posture controls where appropriate
- Tighter rules for admin portals or sensitive resources

The goal is not to make work painful. The goal is to make account misuse difficult.

## Step 6: Watch the System Do the Work for You

Once these controls are in place, contractor access becomes predictable:

- Add contractor to the group, access turns on with guardrails
- Remove contractor from the group, access turns off immediately

No chasing tickets. No sticky notes. No “we’ll remember later.”

## Take Back Control of Contractor Access

Contractors do not have to be a security gamble. With a small amount of setup, you can build a clean, repeatable process that protects your business and makes your IT workload lighter.
