Hack simulator: WordPress attack surface vs. the Next.js edge shield
Why a monolithic CMS is a standing risk to the business that runs on it.
WordPress / monolith attack vectors
Status: high risk of outage- Vulnerable third-party plugins: Every plugin widens the attack surface for SQL injection and zero-day exploits.
- PHP server & direct database access: One compromised web server exposes customer data and passwords.
- WP-Admin brute force & REST API leaks: Open endpoints invite automated botnets to run DDoS attacks.
Next.js 15 on static edge assets
Status: no plugin surface- Read-only static edge assets: No PHP scripts run on the server, so a whole class of CMS attacks has nothing to reach.
- Decoupled headless CMS: Content is edited through secure API tokens, kept fully apart from the frontend.
- Global edge CDN & DDoS protection: Load is spread automatically and bot attacks are turned away in milliseconds.

A classic CMS vs. a Next.js 15 architecture
Side by side, the reasons companies move to a decoupled headless system.
| Criterion | WordPress / Typo3 monolith | Coday Next.js 15 Headless Stack |
|---|---|---|
| Load time & TTFB | 2.0s to 4.5s, rendered on the server for every request | < 0.3s, pre-rendered and served from the edge |
| Security architecture | Vulnerable databases and PHP scripts on the web server | No plugins, no database on the web server |
| Maintenance & updates | Weekly plugin patching, and the site can break with it | No plugin updates, dependencies updated to a plan |
| Editing the content | A cluttered WordPress backend that breaks layouts | Sanity CMS, with a live visual preview |
| SEO & Core Web Vitals | Poor LCP and CLS from scripts nobody optimised | Lighthouse at 90 or above, measured before handover |
Four steps to the new platform
No surprises, no downtime, and every old address keeps somewhere to land.
Audit & URL mapping
We crawl your current website in full and record every URL, meta tag, backlink and image, so the 301 redirect map has no gaps in it.
Next.js & UI/UX development
Your new design is built for you with React 19, TypeScript and TailwindCSS, on a protected staging environment.
Content migration & headless CMS
Every blog post, product page and image goes into Sanity CMS without losses. Your team is shown how to keep the content up to date afterwards.
Zero-Downtime Go-Live
A final pre-launch audit covering PageSpeed and schema validation, then the DNS switch. Your old site stays reachable until the new one takes over.
Your migration is handled by an experienced lead developer
At Coday your migration is not passed down to an inexperienced intern. I, Umutcan Emre Tezgel, plan and write it myself. The same developer writes the code, sets up the redirects and hands the project over, at the fixed price agreed beforehand.
Questions about moving to Next.js
Will I lose my Google rankings when I move to Next.js?
No. Every old address gets a permanent redirect to its new one, the markup stays semantic, and the pages load faster than before. That is what carries a ranking across a move.
What happens to my existing blog posts and products?
They are exported from WordPress or Typo3 and imported into the new content system, so you do not retype anything.
Will my site be offline during the move?
No. The new site is built on a separate staging environment and the switch itself takes a fraction of a second.
What does moving from WordPress to Next.js cost?
Every project is quoted as one fixed price agreed up front. What the price depends on: how many pages there are, how much content has to be moved by hand, how many old addresses need a redirect, and whether you want a content system to edit it yourself.
