OWASP Top 10 coverage
Every build is reviewed against the OWASP Top 10: injection, broken access control, security misconfiguration and the rest, with documented mitigations.
- Injection defence
- Access control
- Secure config
- Crypto failures
Security designed in, not bolted on
Secure web development from the first commit.
Secure web development means building security into the architecture from the first commit, not bolting it on after launch. We hand-code Next.js sites with a strict Content Security Policy, OWASP Top 10 coverage, parameter-bound database queries, row-level security, signed cookies, per-route rate limiting and bot protection on every public form, then hand you an auditable codebase and an operations runbook.

Attack-surface pipeline · system view
Untrusted traffic enters. Six layers of defence inspect, filter and bind it. Only a hardened, safe response leaves. This is the request path on every site we build.

What this fixes
The risks we hear before every brief.
Risk 1
Your current site runs on a stack of third-party plugins.
Every plugin is a supply-chain risk, a performance tax and a renewal invoice waiting to break.
Risk 2
Forms and login pages are unprotected.
Bots scrape your inboxes, fill your CRM with junk and probe relentlessly for credential reuse.
Risk 3
You inherit a site you cannot audit.
When something breaks at 11pm, no one in the building can read the code or trace the fault.
Threat modelling
We map the attack surface before a line of code is written.
The method
Five stages, from threat model to live monitoring.
A repeatable secure software development lifecycle: threat modelling, secure architecture, hardening to OWASP Top 10, penetration testing and ongoing monitoring.
01
Threat model
Map the attack surface, data flows and trust boundaries before a line of code is written.

02
Architect
Server-first design, least-privilege access and secure defaults baked into the foundation.

Defence in depth
Four layers. No single point of failure.
What's included
Every secure build ships with this.
- Next.js App Router build, hand-coded and fully auditable
- Strict Content Security Policy, HSTS and secure-header configuration
- OWASP Top 10 review with documented mitigations
- Honeypot plus rate-limit on every public form
- Parameter-bound Supabase / Postgres queries with row-level security
- Signed, httpOnly cookies and CSRF-resistant server actions
- Written architecture diagram and operations runbook
- A-grade security headers verified before launch
What you receive
Tangible security artefacts, not a checklist.
Hardened architecture diagram
A clear map of every layer of defence, from edge WAF to row-level-secured database.
Security headers report
An A-grade scan of CSP, HSTS and secure headers, verified live before we ship.
Threat model & runbook
The attack-surface model and the incident-response runbook your team can actually follow.
Security posture
Six layers of protection. No single point of failure.
Most agencies treat security as a launch-day checkbox. We engineer it into every layer: OWASP Top 10 coverage, a strict Content Security Policy, hardened database access, bot protection, privacy by design and a fully auditable codebase. Each discipline applies to every build.

02
Content Security Policy
Strict, nonce-based CSP Level 3 that blocks cross-site scripting at the browser, plus HSTS and a full secure-header set.
- Nonce-based CSP
- HSTS preload
- Frame ancestors
- Referrer policy
03
Database hardening
Row-level security and parameter-bound queries mean a compromised query can never read another tenant's data or run injected SQL.
- Row-level security
- Parameterised queries
- Least privilege
- Encryption
04
Bot & abuse protection
Per-route rate limiting, honeypots and bot heuristics on every public surface so forms and logins stay clean and credential-stuffing fails.
- Rate limiting
- Honeypots
- Bot heuristics
- CAPTCHA-free defence
05
Privacy & compliance
GDPR-aware data handling, signed and httpOnly cookies, minimal data collection and clear sub-processor records for procurement.
- GDPR-aware
- Cookie hardening
- Data minimisation
- Sub-processor records
06
Auditable & owner-ready
Conventional structure, named server actions and a written runbook so any senior engineer can audit, operate and extend the build.

- Named actions
- Runbook

FAQ
Questions buyers ask before signing.
What does secure web development actually include?
It includes threat modelling before the build, a strict Content Security Policy, OWASP Top 10 coverage, parameter-bound queries with row-level security, signed cookies, per-route rate limiting, bot protection on public forms, and a written operations runbook. Security is part of the architecture, not an add-on.
Do you work with WordPress or page builders?
No. We migrate off them. Plugin-driven stacks are the single biggest source of supply-chain and configuration vulnerabilities we see. Hand-coded, auditable Next.js is the product.
Do you cover the OWASP Top 10?
Yes. Every engagement is reviewed against the current OWASP Top 10, including injection, broken access control, cryptographic failures and security misconfiguration, with each mitigation documented so your team can verify it.
Can you harden or audit an existing site?
Yes. We run a vulnerability assessment and security-headers audit, document the gaps against OWASP, then either remediate in place or plan a migration to a hardened build, depending on the state of the code.
How do you stop bots and spam on forms?
We layer per-route rate limiting, honeypot fields and lightweight bot heuristics so junk submissions and credential-stuffing attempts fail without forcing your real users through intrusive CAPTCHAs.
Is the site GDPR compliant?
We build GDPR-aware: data minimisation, signed and httpOnly cookies, clear consent handling and documented sub-processors. We are not a law firm, but the technical foundation maps cleanly to what your DPO needs.
Will my team be able to maintain it?
Yes. We use a conventional file structure, named server actions and a written runbook, so any senior engineer can read, audit and extend the build. You are never locked to us.
Do you provide penetration testing?
We run automated scanning and dependency audits as standard, and offer manual penetration testing against the OWASP Top 10 as part of larger engagements or on request.
Ready to lock it down?
Build it secure from day one.
A senior engineer reviews your current surface and walks you through the exact runbook you would receive, on a 15-minute call.
