The practice

Founded on the belief that security deserves the same craft as finance, medicine, or law.

DR.ISO was established by three senior practitioners — a former Big Four partner, an ex-GCHQ consultant, and a lifelong CISO — who had grown quietly frustrated with an industry increasingly optimised for volume rather than mastery.

We remain deliberately small. We accept a limited number of clients each quarter. We measure ourselves not by revenue but by the durability of the security programmes we leave behind.

Principles

Four commitments we hold without compromise.

01

Senior-led, without exception

Every partnership is led by a practitioner with at least fifteen years in information security. No delegation to juniors.

02

Discretion as a default

Confidentiality is operational, not aspirational. NDA by default; client lists on request only.

03

Pragmatism over theatre

We optimise for real risk reduction and audit readiness, not for the thickness of a binder.

04

Partnership, not engagement

Certification is not a project — it is the first year of a relationship. We stay.

“Excellence in security is the sum of small, deliberate choices made when no one is watching.”
— A founding principle
