Security is one of the most important aspects of running an ERP system like NetSuite. With sensitive financial, customer, and employee data stored in the platform, protecting your environment from misuse and cyber threats is critical.
In this blog, weโll cover NetSuite security best practicesโfrom roles and permissions to two-factor authentication (2FA) and data protectionโso you can keep your system safe.
๐ ๏ธ Why NetSuite Security Matters
- Financial Risk: Unauthorized access could expose financial records.
- Compliance: Many industries (e.g., healthcare, finance) require strict controls.
- Reputation: A breach erodes customer trust.
- Business Continuity: A secure system avoids downtime and data loss.
๐ NetSuite is secure by design, but your configuration choices play a big role in keeping it safe.
๐ 1. Use Strong Roles & Permissions
We covered roles in the previous blog, but hereโs the security angle:
- Apply the Principle of Least Privilege โ Users should only access what they need.
- Avoid giving everyone Administrator access.
- Review roles regularly and remove unnecessary permissions.
- Use separate roles for integrations (API connections) instead of reusing human roles.
๐ 2. Enable Two-Factor Authentication (2FA)
NetSuite requires 2FA for administrators and highly privileged roles, but you should expand it to all critical users.
- 2FA = password + secondary code (via app or SMS).
- Helps prevent account takeovers even if a password is stolen.
- Enforce it under: Setup > Users/Roles > Two-Factor Authentication.
๐ Best Practice: Use an authenticator app (like Google Authenticator) instead of SMS for stronger protection.
๐ 3. Monitor Login Audit Trail
NetSuite provides a Login Audit Trail where you can track who logged in, when, and from where.
- Navigate to: Setup > Users/Roles > View Audit Trail
- Look for unusual patterns (e.g., logins from unexpected countries).
- Schedule reports to monitor login activity.
๐ Pro Tip: Combine with Saved Searches to send alerts for suspicious login attempts.
๐ 4. Secure Integrations
Integrations (APIs, connectors, middleware) are often overlooked from a security perspective.
- Use Token-Based Authentication (TBA) or OAuth 2.0 instead of plain passwords.
- Create dedicated integration roles with limited permissions.
- Regularly rotate tokens and credentials.
๐ Never hardcode credentials in SuiteScript or middleware.
๐ 5. Apply IP Restrictions (Where Needed)
For sensitive roles, you can restrict access to NetSuite by IP range.
- Example: Allow finance users to log in only from office IPs.
- Navigate to Setup > Users/Roles > Manage Roles > Restrictions tab.
๐ Use sparinglyโtoo strict restrictions can block remote workers.
๐ 6. Keep an Eye on Release Updates
NetSuite updates twice a year (Release 1 & Release 2). Each release may include:
- Security patches
- Stronger authentication methods
- Deprecation of old APIs
๐ Always test security-related changes in Release Preview.
๐ Real-World Examples
- Finance Department: Restrict vendor payment roles to office IPs + enforce 2FA.
- Warehouse Staff: Give only โViewโ access to invoices, not โEditโ or โDelete.โ
- API Integrations: Create a role with access only to Customers + Sales Orders for a Shopify integration.
โ Best Practices Checklist
โ๏ธ Apply least privilege on all roles.
โ๏ธ Enforce 2FA for all users (not just admins).
โ๏ธ Use TBA or OAuth for integrations.
โ๏ธ Monitor login audit trails.
โ๏ธ Rotate credentials regularly.
โ๏ธ Test security impacts in sandbox and release preview.
โ Final Thoughts
NetSuite security is a shared responsibility: Oracle provides the platform, but you configure the safeguards. By applying strong roles, enforcing 2FA, monitoring logins, and securing integrations, youโll greatly reduce risk and keep your ERP environment safe.
Security isnโt a one-time taskโitโs an ongoing process of review, adjustment, and monitoring.
