business applications

[ 02 ] Problem

Systems that slow you down
more than they help.

Inefficient internal tools, risky migrations and poor access control create fragile environments. These systems limit productivity and increase risk.

01

Fragile architectures

Outages steal the weekend. Upgrades become quarterly projects. The risk budget drains into keeping the lights on — not into roadmap.

02

Risky migrations

When a tenant cutover stalls, the executive calendar doesn't wait. Migrations without rollback become career events — for the wrong reasons.

03

Security gaps

The first security review becomes the most expensive pull request in the project — measured in weeks of re-architecture and delayed go-lives.

04

Tools nobody adopts

Internal apps quietly replaced by Excel. Training budget spent, adoption flat. The tool becomes yet another ticket queue.

[ 03 ] Solution

Platforms built to last.

Three domains, one engineering practice — business applications, Microsoft 365 and security, operated continuously.

Digital Products

Business applications designed to reduce operational friction and accelerate critical workflows.

Problem
Legacy tools block the operational flow. Excel exceptions, shadow IT, processes that depend on a single person.
Solution
Applications designed around the real workflow — TypeScript, React, Node.js, Graph API, Power Platform where it fits. UX and performance treated as SLAs, not nice-to-haves.
Result
Operational friction removed. Critical workflows accelerated. Support load that shrinks instead of growing.
Cloud & M365

Secure Microsoft ecosystems.

Problem
Complex and risky Microsoft ecosystems — tenant sprawl, legacy platforms, weak governance.
Solution
  • Tenant-to-tenant migrations (LUIGI programme)
  • Linux / Zimbra → Microsoft 365
  • Entra ID · identity lifecycle · provisioning
  • Conditional access · Zero Trust posture
  • M365 governance · Purview · DLP · retention
Result
Migrations delivered without rollback weekends. Tenants that pass audit the first time.
Security · position

Security is not a layer we add.

It is built into the platform design itself. Identity, access, data and threat models are decided before the first line of code — not during the pre-audit panic.

How
  • Identity-first architecture (Entra ID)
  • Conditional access · Zero Trust
  • Data protection · Purview · DLP
  • User lifecycle · joiner / mover / leaver
Result
Incidents that stay small. Audits that turn into box-ticking — not re-architecture.
[ 04 ] Proof

Results delivered.

15,000+

Users migrated across a multi-entity group

Phased Microsoft 365 migration on a critical multi-entity architecture — identity sync, rollback checkpoints, zero interruption of operations.

+40%

Adoption lift on a critical internal tool

Workflow redesign and technical rebuild — Excel fallbacks replaced by a product that carries the workflow, not the exception.

Full M365

Access security redesigned end-to-end

Entra ID, conditional access, Zero Trust posture, Purview and DLP — compliance achieved on a live tenant, without a rewrite.

[ 05 ] Why EPIXID

Why EPIXID.

Direct technical expertise

The person who scopes is the one who ships. A direct line to the architect — not a project manager reading from a deck.

No commercial middleman

No offshore black box, no subcontractor chain, no account-executive layer between you and the engineering work.

Execution-focused

Working software on Friday, not a deck on Monday. Discovery and Sprint 0 are fixed-fee so budget and timeline are locked before build.

Security built in from day one

Identity, data and threat models designed before code. Audit review becomes box-ticking, not re-architecture.

[ 03 ] The EPIXID Universe

One family.
Six products.

Beyond consulting, EPIXID builds and ships its own SaaS products — from multi-tenant API backbones to hospitality OS and EdTech platforms.
