Website development
Websites and web apps that load fast, rank, and convert
Your website is your hardest-working salesperson and, for most companies, the easiest way in for an attacker. We build sites that load in under a second, rank for the searches that matter, turn visitors into enquiries, and do not become the breach story.
- Fixed-price proposal within 48 hours
- Core Web Vitals in the green, guaranteed
- Security tested before launch
The problem
Why most builds disappoint
Every second of load time costs conversions, and every plugin added to a page builder is another component someone else maintains and an attacker can probe. The result is familiar: a site that scores 40 on mobile, ranks below competitors with worse products, and runs a dozen plugins nobody has updated in a year.
We build differently. Modern frameworks that render pages ahead of time and serve them from the edge, so they are fast by construction rather than by caching tricks. Structured content and technical SEO baked into the templates, so every new page you publish is already optimised. Clear page structures designed around the one action each visitor should take.
And because we are a security firm, the site goes live with strict security headers, a hardened CMS, no exposed admin surface, and a security test run by the same team that tests SaaS platforms for SOC 2 audits. Enterprise buyers check your website. Ours pass.
The difference
A typical agency, and us.
| Typical agency | innsecs | |
|---|---|---|
| Pricing | Hourly, or a low quote that grows | Fixed price, scope written down |
| Speed | Page builder, 40 on mobile Lighthouse | 90+ on mobile, Core Web Vitals in the green |
| SEO | A plugin and a keyword field | Schema, sitemaps, metadata and internal linking in the templates |
| Security | Outdated plugins, exposed /wp-admin | Hardened, headers set, tested before launch |
| Editing | Call the agency to change a headline | A CMS your team actually enjoys using |
What we build
From first version to products that scale.
Marketing websites
Company and product sites designed around conversion: clear positioning, proof, and one obvious next step on every page.
Landing pages and campaigns
High-intent pages for paid traffic and launches, built to load instantly and to be A/B tested without a developer.
Web applications and SaaS
Dashboards, portals and full SaaS products with authentication, roles, billing and multi-tenancy designed by people who test them for a living.
E-commerce
Headless Shopify or custom storefronts with fast product pages, a checkout that does not leak card data, and PCI DSS scope kept small.
Headless CMS and content sites
Sanity, Contentful or Payload, structured so marketing can publish pages and posts without touching code or breaking layouts.
Redesigns and migrations
Move off a slow or compromised WordPress site without losing rankings: every URL mapped, every redirect tested, search traffic monitored after cutover.
Secure by default
Built by people who break these for a living.
We spend most of our week finding vulnerabilities in other teams’ products. Everything we learn goes into what we build for you.
Strict security headers
Content Security Policy, HSTS, frame protection and referrer policy configured and verified, not left to defaults. Graded A+ before launch.
strict-transport-security: max-age=63072000 content-security-policy: default-src 'self'
No exposed admin surface
The CMS is hosted separately behind SSO and MFA. There is no login page on your public domain for bots to brute force.
Forms that do not become a liability
Server-side validation, rate limiting, bot protection and spam filtering on every form, with submitted data handled in line with GDPR.
Minimal third-party code
Every script on the page justified and reviewed. Analytics and tag managers configured so a compromised vendor cannot read form fields.
Dependencies kept current
Automated vulnerability scanning and dependency updates on every build, so the site does not quietly rot after handover.
Security test before launch
The site and any application behind it tested by our team against the OWASP Top 10, findings fixed and retested before the domain is switched over.
How it works
From call to launch, no surprises.
- 01
Scoping call and fixed quote
Week 0
Thirty minutes on your goals, your audience and what the site must achieve. A written proposal with a fixed price and timeline follows within 48 hours.
- 02
Strategy and structure
Week 1
Keyword and competitor research, sitemap, and the conversion path for each page type. We decide what each page is for before deciding what it looks like.
- 03
Design
Weeks 2–3
High-fidelity designs for desktop and mobile in Figma, reviewed together. Two rounds of revisions included, and no development starts until you approve.
- 04
Build on a live preview
Weeks 3–6
Every change deployed to a private preview URL you can open on any device. You see the real site taking shape, not screenshots.
- 05
Test, harden and launch
Final week
Performance, accessibility, SEO and security checks, redirects verified, analytics wired up. Then a zero-downtime switch of your domain.
- 06
Handover and growth
After launch
CMS training for your team and thirty days of included support. Optional monthly retainer for new pages, experiments and conversion optimisation.

Our promises
In the contract, not the brochure.
Fixed price, held
The figure in your proposal is the figure you pay. New ideas are welcome and quoted before they are built.
Green Core Web Vitals
If the launched site does not pass Core Web Vitals on mobile, we keep working on it at no cost until it does.
You own everything
Your repository, your hosting account, your CMS, your domain. No proprietary builder and no lock-in.
No ranking cliff
On redesigns, every existing URL is mapped and redirected. We monitor search traffic for 60 days after launch and fix anything that drops.
A custom marketing site typically starts at $6,000 and a larger content and SEO-led site around $14,000. Web applications are scoped individually, usually from $28,000. You get a fixed figure in writing before anything starts.
Three to five weeks for a marketing site, five to eight for a larger growth site. Web applications are delivered in phases, with something usable live early.
Yes. Every site comes with a headless CMS set up for your content, and a training session for your team. Changing a headline, adding a page or publishing a post never needs a developer.
Not if it is done properly. We map every existing URL, set up permanent redirects, keep the content that ranks, and monitor search traffic for 60 days after launch. Most sites we migrate gain traffic because they become faster.
They are fine for some sites and we will tell you if yours is one. For a business site that needs to be fast, rank well and stay secure, a modern framework with a headless CMS is quicker for visitors, cheaper to maintain and has a far smaller attack surface.
We structure every page around conversion and can write the copy, or work with your team or copywriter. Either way, the messaging is agreed before design starts.

Tell us what you want to build. We will scope it properly, quote a figure that does not move, and tell you honestly if the timeline you have in mind is realistic.
No sales sequence. A scoping call and a written proposal cost nothing. See published pricing first if you prefer.
