# Next.js 16 + Turbopack Migration for Cybersecurity Company Websites

## The Problem

Security company websites built on older Next.js versions suffer from:
- Slow dev server cold starts (10-15s) killing iteration speed
- Webpack-based builds taking 2-3x longer than necessary
- Deprecated async API patterns causing silent runtime bugs
- No filesystem caching between restarts — every session starts from zero

**Result:** Developers waste time waiting on builds instead of shipping features that build client trust.

## The Solution

Migrate to Next.js 16 with Turbopack as the default bundler — no extra config needed. Turbopack is now stable for both dev and production, delivering:
- 2-5x faster production builds
- Up to 10x faster Fast Refresh
- Filesystem caching on disk between restarts (stable in 16.1)
- Automatic handling of transitive external dependencies

## Use Cases

- MDR/SOC firms rebuilding their service pages for faster client-facing performance
- GRC consultancies whose compliance portals need snappy load times for credibility
- Security founders iterating quickly on landing pages during outreach campaigns

## Impact

- Build time: ~11s → ~4s (Turbopack)
- Dev restart: near-instant with filesystem cache
- Zero additional licensing cost
