PostHog Enterprise RBAC

Overview

Configure enterprise-grade access control for PostHog integrations.

Prerequisites

• PostHog Enterprise tier subscription
• Identity Provider (IdP) with SAML/OIDC support
• Understanding of role-based access patterns
• Audit logging infrastructure

Role Definitions

Role	Permissions	Use Case
Admin	Full access	Platform administrators
Developer	Read/write, no delete	Active development
Viewer	Read-only	Stakeholders, auditors
Service	API access only	Automated systems

Role Implementation

enum PostHogRole {
  Admin = 'admin',
  Developer = 'developer',
  Viewer = 'viewer',
  Service = 'service',
}

interface PostHogPermissions {
  read: boolean;
  write: boolean;
  delete: boolean;
  admin: boolean;
}

const ROLE_PERMISSIONS: Record<PostHogRole, PostHogPermissions> = {
  admin: { read: true, write: true, delete: true, admin: true },
  developer: { read: true, write: true, delete: false, admin: false },
  viewer: { read: true, write: false, delete: false, admin: false },
  service: { read: true, write: true, delete: false, admin: false },
};

function checkPermission(
  role: PostHogRole,
  action: keyof PostHogPermissions
): boolean {
  return ROLE_PERMISSIONS[role][action];
}

SSO Integration

SAML Configuration

// PostHog SAML setup
const samlConfig = {
  entryPoint: 'https://idp.company.com/saml/sso',
  issuer: 'https://posthog.com/saml/metadata',
  cert: process.env.SAML_CERT,
  callbackUrl: 'https://app.yourcompany.com/auth/posthog/callback',
};

// Map IdP groups to PostHog roles
const groupRoleMapping: Record<string, PostHogRole> = {
  'Engineering': PostHogRole.Developer,
  'Platform-Admins': PostHogRole.Admin,
  'Data-Team': PostHogRole.Viewer,
};

OAuth2/OIDC Integration

import { OAuth2Client } from '@posthog/sdk';

const oauthClient = new OAuth2Client({
  clientId: process.env.POSTHOG_OAUTH_CLIENT_ID!,
  clientSecret: process.env.POSTHOG_OAUTH_CLIENT_SECRET!,
  redirectUri: 'https://app.yourcompany.com/auth/posthog/callback',
  scopes: ['read', 'write'],
});

Organization Management

interface PostHogOrganization {
  id: string;
  name: string;
  ssoEnabled: boolean;
  enforceSso: boolean;
  allowedDomains: string[];
  defaultRole: PostHogRole;
}

async function createOrganization(
  config: PostHogOrganization
): Promise<void> {
  await posthogClient.organizations.create({
    ...config,
    settings: {
      sso: {
        enabled: config.ssoEnabled,
        enforced: config.enforceSso,
        domains: config.allowedDomains,
      },
    },
  });
}

Access Control Middleware

function requirePostHogPermission(
  requiredPermission: keyof PostHogPermissions
) {
  return async (req: Request, res: Response, next: NextFunction) => {
    const user = req.user as { posthogRole: PostHogRole };

    if (!checkPermission(user.posthogRole, requiredPermission)) {
      return res.status(403).json({
        error: 'Forbidden',
        message: `Missing permission: ${requiredPermission}`,
      });
    }

    next();
  };
}

// Usage
app.delete('/posthog/resource/:id',
  requirePostHogPermission('delete'),
  deleteResourceHandler
);

Audit Trail

interface PostHogAuditEntry {
  timestamp: Date;
  userId: string;
  role: PostHogRole;
  action: string;
  resource: string;
  success: boolean;
  ipAddress: string;
}

async function logPostHogAccess(entry: PostHogAuditEntry): Promise<void> {
  await auditDb.insert(entry);

  // Alert on suspicious activity
  if (entry.action === 'delete' && !entry.success) {
    await alertOnSuspiciousActivity(entry);
  }
}

Instructions

Step 1: Define Roles

Map organizational roles to PostHog permissions.

Step 2: Configure SSO

Set up SAML or OIDC integration with your IdP.

Step 3: Implement Middleware

Add permission checks to API endpoints.

Step 4: Enable Audit Logging

Track all access for compliance.

Output

• Role definitions implemented
• SSO integration configured
• Permission middleware active
• Audit trail enabled

Error Handling

Issue	Cause	Solution
SSO login fails	Wrong callback URL	Verify IdP config
Permission denied	Missing role mapping	Update group mappings
Token expired	Short TTL	Refresh token logic
Audit gaps	Async logging failed	Check log pipeline

Examples

Quick Permission Check

if (!checkPermission(user.role, 'write')) {
  throw new ForbiddenError('Write permission required');
}
