Security Architecture

Security architecture that engineering teams can build on

Define security reference architectures, design patterns and review processes that scale across engineering teams.

The problem

Why this matters

Security that is added after systems are designed is expensive and incomplete. Without shared reference architectures and design review, each team solves the same security problems differently — and some do not solve them at all.

Common challenges

  • Inconsistent security patterns across products and teams
  • Design reviews that slow delivery or happen too late
  • Legacy systems that cannot meet modern control expectations
  • Security requirements that are vague or untestable

Our approach

How we work

  1. Understand the estate

    Review current architecture, business priorities and regulatory obligations.

  2. Define patterns

    Create reference architectures for common workload types.

  3. Embed review

    Introduce lightweight, risk-based design review in the delivery lifecycle.

  4. Measure

    Track adoption of patterns and residual risk over time.

FAQ

Frequently asked questions

Can you act as an extension of our architecture team?

Yes. Many engagements are embedded: we work alongside your architects on live designs while building reusable patterns.
