We work where operations
cannot stop.
We design, migrate, run and protect the critical infrastructure behind banks, payments firms and fintechs in the UK and Brazil.
:: BOARD SELF-ASSESSMENT COMING UP
Operational Resilience Evidence
We test whether your important business services stay within impact tolerances when a provider fails, including a cloud provider.
:: VMWARE RENEWAL APPROACHING
VMware Exit TCO Assessment
Broadcom’s licensing changes have turned renewal into a business decision. We model renewal against Red Hat OVE, Hyper-V and public cloud using your real inventory.
:: ENTERING BRAZIL
Sovereign Landing Zone
A landing zone designed around Banco Central requirements from day one, with a sovereign copy of your data in Brazil and one team across London and São Paulo.
Important business services, impact tolerances, third-party risk. We engineer the infrastructure that lets you evidence them: under PRA and FCA operational resilience rules, under the UK critical third parties regime and, for EU entities, under DORA.
One core: critical infrastructure engineering.
Six services, the same engineering from design to operations.
:: Architecture & Assessment
Diagnosis and design before the investment decision.
:: Migration & Modernisation
Critical workloads moved between data centres, clouds and virtualisation platforms without stopping operations.
:: Resilience
DR, high availability and cyber resilience, with evidence for your supervisor.
:: Run, Operations & SRE
24/7 operations and reliability engineering by the team that built the environment.
:: Environment Security
Penetration testing, managed SOC and hardening where the infrastructure runs.
:: Quantum
Cryptographic inventory and migration to post-quantum algorithms.
:: ENGINEERING DECISIONS
Decisions we made, and what happened next.
Payments fintech headquartered in London
THE DECISION
Build recovery in Frankfurt before moving production, in three phases between February 2024 and May 2025.
THE RESULT
From a single data centre in Iceland to three regions running at once, in Frankfurt, Amsterdam and London. The estate now supports more than 300,000 merchants in more than 15 countries.
3 regions
Brazilian govtech, Hyper-V to Red Hat OVE
THE DECISION
Rather than add resources to an environment running at its limit, replace the virtualisation layer and design observability in from the start.
THE RESULT
Database volumes from 6 to 9 Gb/s on non-sequential writes.
6 → 9 Gb/s
:: HOW WE DELIVER
A physically air-gapped recovery anchor in Brazil.
heimr guard keeps recovery copies on air-gapped tape in an IBM Diamondback library at Ascenty, São Paulo, in heimr’s custody. For UK and EU firms operating in Brazil, it is the sovereign anchor of the Brazilian landing zone.
Isolated. Air-gapped tape, out of ransomware’s reach.
Sovereign. Data stays in Brazil, under heimr’s control.
Provable. Recovery tested and documented for audit and supervision.
