A website that can prove it.
Most agencies promise speed, security and compliance. We publish the measurements.† Sigvern engineers native WordPress systems that audit themselves — every script counted, every submission guarded, every verdict filed where your team can read it.

Contents · what we actually do
One team. The whole system.
Strategy, creative systems and production engineering in the same operating room — so the website behaves like a growth asset with a paper trail, not a brochure with opinions.
-
Experience architecture
→Information architecture, page systems and conversion paths designed around what buyers do, not what stakeholders hope.
-
Native WordPress engineering
→Full Site Editing themes and Gutenberg systems your editors can own on day one. No page-builder hostage situations.
-
Security engineering
→Fifteen server-side controls on every submission, an append-only audit trail, and a deny-first posture across the stack.
-
Compliance readiness
→WCAG 2.2 AA, GDPR and consent governance handled as engineering constraints — with exportable evidence, not assurances.
-
Performance operations
→Script and stylesheet budgets the build enforces. When a change would slow the page, it never reaches the page.
-
Growth instrumentation
→Measurement plans and experiment cadence tuned to revenue signals — decision-ready analytics in 72 hours, not quarters.

Dossier · since 2011
Fifteen years of digital marketing and development. Filed, not framed.
We’ve shipped campaigns and codebases since 2011 — through three eras of Google core updates, two WordPress editor revolutions and more replatformings than we care to admit. Trends came and went. The habit of measuring everything stayed.
That experience hardened into instruments we build and maintain in-house — because off-the-shelf plugins rarely survive our own audits.
- Forms platform
- Server-validated submissions behind fifteen independent security controls, with retention rules built in.
- Consent gateway
- Privacy choices honoured before any optional script loads — jurisdiction-aware, evidence attached.
- Navigation system
- Accessible mega-menus and mobile drawers, native to the WordPress editor. Zero jQuery.
- Audit tooling
- Performance, security and accessibility snapshots that export as one procurement-ready pack.
Managed infrastructure
We engineer and operate the platform behind every site.
Sigvern sites run on Google Cloud infrastructure that our team configures, monitors and audits. Confidential computing will be available for workloads that require stronger protection while data is in use. We own the operating model, the controls and the evidence.
Governed budgets
Every page carries a script and stylesheet budget. When a change breaks it, the build says no — long before a visitor would ever feel it.
Evidence on demand
Security, performance, consent and accessibility snapshots export as one pack. Procurement asks on Monday. You answer on Monday.
Accessibility as a contract
Keyboard paths, focus order and contrast get verified on every release — and the verdicts are filed, dated and kept.
