About us
Empowering AI through secure infrastructure and intelligent automation
An IT and AI infrastructure consultancy with more than 28 years of hands-on experience.
Who we are
Infrastructure and security experts, since 1998
Serra Consultancy Services Ltd is a London-based consultancy specialising in AI/ML infrastructure, DevOps/DevSecOps, hybrid cloud engineering and cybersecurity. Our roots are in Red Hat, SUSE and Solaris UNIX administration and security auditing for telecoms, GSM operators, banks and government.
Today we help organisations build secure, GPU-optimised, production-grade platforms across AWS, Azure, Google Cloud, Red Hat OpenShift AI and SUSE AI, and we have delivered high-scale systems for e-commerce, enterprise, telecoms, public sector, pharmaceutical and finance clients.
Why Serra
What sets us apart
Mission-critical mindset
Decades running systems where downtime is not an option, from telecom cores to banking and government platforms.
Security by design
SC-cleared engineering, CIS hardening, zero-trust networking and compliance (ISO 27001, PCI, SOX) built into everything we deliver.
Hands-on at every layer
From bare-metal GPUs and InfiniBand to Kubernetes, pipelines and cloud governance, one team that understands the whole stack.
AI-assisted, human-accountable
We use AI agents to move faster, with guardrails: dry runs, deny-lists for irreversible changes and review against live state before any apply.
Open source at heart
Long-standing commitment to Linux, UNIX and open-source tooling, including published books and conference talks.
Knowledge transfer
We train your people as we work, so your team owns the solution long after we leave.
