Security Architecture Design & Review

Designed for Assurance

Today’s CISOs face pressure on all fronts, from boardroom expectations and digital transformation to a constantly evolving threat landscape and an unforgiving regulatory environment.

At 2T Security, we help you meet those demands with architecture that is secure by design, built for compliance, and proven in the most sensitive sectors.

Whether managing national infrastructure, handling classified workloads, or modernising legacy estates, our NCSC-assured Security Architecture service provides you with a clear path forward.

THE 2T SECURITY ARCHITECTURE ADVANTAGE

Too many security strategies rely on reactive controls.

We believe in prevention through intelligent design. Our architecture engagements include:

Security Requirements Definition

We align architecture with your business goals, threat profile, and risk appetite, ensuring it enables operations rather than restricts them.

Threat Modelling and Attack Path Analysis

We run workshops to uncover the most likely and dangerous ways your systems could be compromised and then design solutions.

Detailed Architecture Design

From zones and conduits to access controls, trust boundaries, and data flows, we map how your environment should operate—and how to protect it.

Zero Trust & Data Centric Security

We incorporate best‑practice models, including Zero Trust, defence‑in‑depth, secure enclaves, and least privilege, to ensure your data is protected wherever it travels.

Compliance & Assurance Reviews

We assess current-state security posture against internal policy and external frameworks (e.g. GDPR, NIS2, ISO 27001, IEC 62443) and build recommendations into your target architecture.

Hands-On Implementation Guidance

Architecture isn’t theoretical. We work with your engineering teams to redesign or uplift security controls where needed, providing templates, artefacts, and hands-on support.

Security Requirements Definition

We align architecture with your business goals, threat profile, and risk appetite, ensuring it enables operations rather than restricts them.
