CP Diagnostics Suite puts the diagnostic power of an experienced sysadmin right inside your WordPress admin bar. Test real server conditions, generate shareable support reports in one click, and resolve issues in minutes, not days.
🧭 4 Guided Readiness & Health Suites
One click runs an entire battery of tests, returning clear Pass, Warning, and Critical indicators with actionable remedies:
🌐 Website Readiness Suite
Inspects full domain health end-to-end: authoritative DNS, TCP handshake, TLS certificate validity, and HTTP response statuses to ensure your website is fully primed for traffic.
📧 Email Readiness Suite
Eliminate spam folder issues. Automatically checks MX records, SPF syntax, DMARC policies, DKIM readiness, BIMI branding, and TLS-RPT delivery configurations.
🩺 WordPress Health Suite
Diagnoses loopback requests, REST API endpoints, WP-Cron task backlog, HTTPS transport integrity, and outbound WordPress.org repository connectivity.
🔄 Migration Comparison Suite
Compare source and destination servers side-by-side before changing DNS records. Verify TLS certificates, PHP limits, and HTTP response codes to prevent surprise downtime.

Built for Security-Conscious Administrators
Diagnostics tools must never introduce new vulnerabilities. CP Diagnostics Suite is engineered from the ground up to uphold the strictest security standards:
- Custom Capability Protection: Restricted strictly to users with the dedicated
run_cp_network_toolscapability and verified WP nonces. - Automatic SSRF Protection: Rejects loopback, link-local, private, and reserved IPs by default (with an explicit admin toggle for corporate intranets).
- Zero Frontend Footprint: Leaves 0 scripts, 0 styles, 0 shortcodes, and 0 unauthenticated endpoints on the public frontend.
- Rate Limiting & Concurrency Locks: Built-in burst throttling protects your hosting CPU from accidental or malicious load spikes.
- Client-Side Redaction: Generates clean, Markdown & JSON reports with sensitive tokens automatically masked for safe sharing with hosting support.

❓ Frequently Asked Questions
Does CP Diagnostics Suite slow down my website?
Not at all. The plugin executes only on-demand when an authorized administrator initiates a test inside the WordPress admin dashboard. It injects zero scripts, styles, or tracking codes into your public-facing pages.
How does TCP Ping differ from regular ICMP ping?
Standard shared/cloud PHP hosting environments prohibit raw ICMP socket creation for security. TCP Ping tests actual connection setup times against target application ports, providing accurate, practical connectivity measurements without requiring root server access.
Can I delegate access to junior developers or support staff?
Yes! Access is tied to the granular run_cp_network_tools WordPress capability. You can assign this capability to specific roles or users using any role-management plugin (such as User Role Editor or Members).
