Secure-by-design infrastructure for environments where trust is non-negotiable.
Proven delivery of secure infrastructure within public sector and regulated environments — identity, PKI, network security, and externally facing systems designed to pass assurance, not just audits.
Where we specialise.
PKI & Certificate Services
A genuine specialism: design, build, migration, recovery, and governance of PKI — from Windows ADCS estates to OpenSSL certificate authorities, auto-enrolment, and SCEP/NDES.
Identity & access management
Active Directory, Entra ID, federation, and privileged access management — including CyberArk session management integrated with your tooling.
Network & perimeter security
Firewall and gateway architecture, segmentation strategies, secure remote access, and web application protection across cloud and on-premise estates.
Secure external-facing services
Risk assessment and hardening of internet-facing platforms — threat mitigation, secure publishing patterns, and assurance evidence for stakeholders.
Compliance & assurance
Experience delivering within formal public-sector security standards and regulated frameworks — with the documentation and governance trail to prove it.
Security posture reviews
Scoped reviews of infrastructure security posture with practical findings, prioritised recommendations, and a roadmap your team can execute.
Expiring root CA? Undocumented PKI? We’ve seen it before.
Certificate infrastructure is often inherited, undocumented, and quietly critical. We rescue, rebuild, and document PKI estates — then train your teams to run them with confidence.
- Expedited migrations when certificates are close to expiry.
- Recovery of broken or undocumented deployments.
- Handover with full documentation and BAU training.
Anonymised delivery evidence.
- On a nationally significant public-sector programme, implemented a global front door with web application firewall policy and an application gateway, giving resilient ingress with DDoS mitigation and zero-trust access controls, then scoped the ITHC with the customer’s independent testing supplier.
- For a UK Government OFFICIAL-grade hosting and reseller platform, deployed privileged access management across a highly segmented network — the identity and access control expectations examined under NCSC CAF objective B.
- For an IL3 and OFFICIAL government cloud platform, designed the security monitoring and operational automation toolset that CAF objectives C and D examine, including SCOM integration and a customer self-service patching portal.
- For a regulated water-sector organisation, assessed and safely decommissioned a certificate authority incorrectly deployed on a domain controller, proving dependency status with Certutil and PKIview before any change was made.
Most of this work sits under non-disclosure agreements, so engagements are described by shape, sector, and scale rather than by client name. How we work explains what can be shared and how.
