Three pressures that all land on identity
Customers and regulators want evidence
NIS2, DORA and the Cyber Resilience Act push security down the supply chain. Your largest customer may already be sending you a security questionnaire.
Attackers log in rather than break in
Stolen credentials, API keys and standing admin rights are among the most common ways in. Fewer permanent privileges means less to steal.
Machines now outnumber people
Service accounts, API keys and AI agents multiply far faster than anyone reviews them, and many keep access long after their purpose ends.
Who we work with
Senior advisory for organisations of 50+ people that need to prove their security to a regulator, a major customer or an auditor.
Regulated Entities
Organisations subject to NIS2, DORA, and other critical infrastructure requirements across Europe.
Strategic Suppliers
Service providers needing to demonstrate defensible identity governance to win and maintain major enterprise contracts.
Growing Scale-ups
Companies with 50+ staff moving beyond ad-hoc access management towards a formal Zero Trust architecture.
From first conversation to a clear plan
1. Discuss your situation
Tell us what is driving the need: an audit, a customer questionnaire or unclear ownership of access.
2. Agree a focused review
A fixed-scope Identity Security Review, typically 5 to 7 days, with deliverables agreed before work starts. We assess with read-only, least-privilege access.
3. Decide with evidence
We walk your team through findings, priorities and proposed owners. Where you need ongoing direction, vCISO support keeps it moving.
