Enterprise security consultancy

Security that holds up under audit.

We design security architecture and governance for organisations where a control failure is a business event — then we help you prove the controls work.

What we do

Three practices, engaged separately or together. Every engagement ends with artefacts your team owns — not a slide deck.

01

Security Architecture

Zero-trust design, cloud architecture, and reference patterns that delivery teams can actually build against.

  • Architecture reviews
  • Zero-trust roadmaps
  • Decision records

02

Governance & Assurance

Control frameworks and evidence pipelines that prove what you claim — to auditors, regulators, and your board.

  • SOC 2 / HIPAA / PCI DSS
  • Control rationalisation
  • Board reporting

03

AppSec & DevSecOps

Guardrails in the pipeline instead of gates in front of it, so security scales with the platform.

  • Programme design
  • Supply chain security
  • Pipeline guardrails

Practitioner-led, enterprise-proven

Phenom Security is led by Aaron Smith — a hands-on security architect with 20+ years securing Fortune 100 enterprises. The person who designs your governance framework is the person who writes the code that enforces it.

What Dies First When You Retire a Service

Retiring a service is an ordered operation with a preservation gate that has to be verified before anything is destroyed, and a list of consumers that no inventory holds.

What Leaks Through the Pipe That Publishes

A private-to-public sync excluded every file it was supposed to exclude and still published the committer's identity, the commit bodies, and a sentence naming the directory it had just hidden.
