EXPERIENCE CASE NOTES

Evidence, with honest attribution.

Selected anonymised leadership experience that demonstrates scale and method. We never invent client logos, testimonials or consultancy outcomes.

01 / GLOBAL DNS TRANSFORMATION2,000+domains

Moving a global domain estate to a resilient managed DNS platform

Leadership experience from a large enterprise transformation, presented anonymously to protect employer and platform confidentiality.

Challenge

A fragmented global domain estate required controlled migration with minimal operational risk and clear ownership across many application teams.

Approach

Designed a phased migration approach, structured domains into manageable waves, coordinated validation and exception handling, and aligned operational readiness with change governance.

Outcome

More than 2,000 domains progressed through a repeatable migration model, with improved governance and substantial forecast cost efficiency.

02 / EXTERNAL ATTACK SURFACE588records assessed

Turning dangling DNS discovery into an actionable control

An anonymised enterprise experience note—not a claim of a Cybersecurity Consultants Ltd client engagement.

Challenge

Cloud-linked DNS records lacked consistent ownership and could outlive their target resources, creating potential subdomain takeover exposure.

Approach

Defined an automated discovery and matching approach, separated confirmed dependencies from missing targets, and created an operating procedure for triage, ownership and remediation.

Outcome

An initial 588 CNAME records were assessed: 516 matched expected resources and 72 required further ownership or remediation investigation.

03 / PKI OPERATIONS8,000+certificate scale

Designing machine-identity change for a complex enterprise estate

Drawn from senior professional and programme experience across enterprise PKI and certificate lifecycle management.

Challenge

Thousands of certificates and endpoints required stronger discovery, lifecycle control, migration planning and accountability without interrupting critical services.

Approach

Applied risk-based discovery, stakeholder mapping, target lifecycle design, platform integration thinking and phased adoption planning.

Outcome

A scalable operating model and migration structure designed for estates spanning thousands of certificates and distributed technical owners.
