Your support ticketing system handles sensitive customer information — names, email addresses, account details, and sometimes payment-related inquiries. A security breach in your help desk doesn't just expose data; it destroys the trust your customers placed in you.
Support Pro was built with security as a foundational requirement. Every feature described below is included in the plugin — not as an add-on or premium module.
Security Features
Nonce Verification
Every form submission in Support Pro is protected with WordPress nonce tokens. This prevents Cross-Site Request Forgery (CSRF) attacks — ensuring that form submissions come from your site, not a malicious third party.
- ✓wp_nonce_field() on every admin and customer form
- ✓check_admin_referer() validation on all form handlers
- ✓Nonce tokens expire after 24 hours for added security
- ✓AJAX requests include nonce verification
Role-Based Access Control
Support Pro uses WordPress capabilities to control who can see and do what. Admin, agent, and viewer roles ensure that each team member only has access to the features they need.
- ✓Admin: full access to all settings, tickets, and reports
- ✓Agent: can view and respond to assigned tickets only
- ✓Viewer: read-only access to ticket history
- ✓Custom capabilities for granular permission control
- ✓WordPress user roles respected and extended
Input Sanitization & Output Escaping
All user-supplied data is sanitized before storage and escaped before display. This prevents Cross-Site Scripting (XSS) attacks and ensures that malicious code cannot be injected through ticket content, comments, or form fields.
- ✓sanitize_text_field() on all text inputs
- ✓sanitize_email() on email fields
- ✓wp_kses_post() for rich text content
- ✓esc_html() and esc_attr() on all output
- ✓File upload validation (type, size, extension)
Prepared SQL Statements
Every database query uses WordPress $wpdb->prepare() with parameterized queries. No raw SQL queries are ever executed with user-supplied data, completely preventing SQL injection attacks.
- ✓$wpdb->prepare() on every query with user data
- ✓Parameterized queries for all CRUD operations
- ✓No string concatenation in SQL queries
- ✓Database table prefixing for multi-site compatibility
Email Security
Support Pro's email notification system supports multiple providers (WordPress wp_mail, SendGrid, SMTP) with proper authentication and anti-spoofing measures.
- ✓SPF/DKIM/DMARC support via SendGrid integration
- ✓HTML email templates with proper escaping
- ✓Variable substitution with sanitized data only
- ✓Email delivery logging for troubleshooting
- ✓No customer PII in email subject lines
Activity Logging & Audit Trail
Every action on every ticket is logged with timestamps and user attribution. This provides a complete audit trail for compliance, training, and dispute resolution.
- ✓Automatic logging of all ticket actions
- ✓User attribution on every log entry
- ✓Timestamped entries for forensic analysis
- ✓Exportable logs for compliance audits
- ✓Cannot be modified or deleted by non-admins
Compliance & Compatibility
WordPress Coding Standards
All code follows WordPress PHP and JavaScript coding standards, ensuring compatibility and security best practices.
GDPR Support
Data stays on your server. Ticket data can be exported or deleted on request. Access controls limit who can view customer information.
Data Retention
Configurable data retention policies. Set automatic cleanup schedules for resolved tickets and inactive accounts.
Compatibility
Compatible with WordFence, Sucuri, iThemes Security, and other popular WordPress security plugins.
Your Data Stays on Your Server
Unlike SaaS help desk platforms (Zendesk, Freshdesk, Help Scout), Support Pro runs entirely on your own WordPress installation. Your ticket data, customer information, and support history never leave your server. You control the backups, the access, and the retention policies.
This is a fundamental security advantage: no third-party vendor has access to your customer data. No vendor lock-in. No data migration headaches if you switch platforms.
