Shipping an MVP or data-heavy product? Start with Python. Building cloud infrastructure, APIs, or DevOps tools? Go is the sweet spot. Writing a cryptographic library, game engine, or WebAssembly module? Rust is worth the investment. Running a large enterprise with Java expertise or regulated-industry requirements? Java (Spring Boot / Quarkus) is the proven choice.

Rust is the gold standard for memory-safe systems. Go is the practical choice for secure cloud services with a low dependency footprint. Java (with Spring Security) is the enterprise standard for regulated industries. For frontend, Astro or SvelteKit ship minimal JavaScript (smallest attack surface). Pair with HTMX on the backend for near-zero client JS.
The fewer dependencies you have, the smaller your attack surface. Go and Rust have smaller ecosystems — which is actually a security advantage. In Node.js, a typical app pulls in 1,000+ transitive packages. Confirmed real-world supply chain attacks against npm include event-stream (cryptocurrency theft, 2018), ua-parser-js (crypto miner + password stealer, 2021), node-ipc (deliberate wiper malware, 2022), and colors.js (deliberate corruption, 2022). Prefer pnpm + lockfile + npm audit + Socket.dev scanning in CI. Evaluate each new dependency critically — ask: "do I really need this package?"
Top-10 OWASP vulnerabilities apply regardless of stack: injection attacks (SQL, command, template), broken authentication, insecure deserialization, using components with known vulnerabilities. Tools like Snyk, SonarQube, and CodeQL (free for open source) catch most of these automatically.
