Digital Trust, eIDAS and Trust Services Consulting

I help organisations understand, design, integrate and govern digital trust services.

Electronic signatures, electronic seals, electronic time stamping, certificates, PKI, validation and digital evidence management have become essential for securing digital processes, establishing legal proof and meeting regulatory requirements.

My role is to help organisations make the right technical, regulatory and operational decisions, whether they need to use existing trust services, integrate electronic signature or seal solutions into business processes, or design high-criticality trust services.

Areas of expertise

Trust service use cases

I help organisations identify the right trust services for their business needs: electronic signatures, electronic seals, electronic time stamping, certificates, validation, digital archiving and electronic evidence management.

The objective is to turn a legal, business or regulatory need into an operational framework that is reliable, understandable and under control.

eIDAS compliance and ETSI requirements

I support organisations in analysing, understanding and implementing eIDAS requirements and the ETSI standards applicable to trust services.

This may include gap analysis, audit readiness, documentation review, service governance and the structuring of expected audit evidence.

PKI architecture and qualified trust services

I work on the design, evolution and security of PKI architectures and critical trust services: certification authorities, registration authorities, OCSP / CRL services, HSMs, key lifecycle management, high availability and multi-site architectures.

Technical governance and security

I help structure the technical decisions, responsibilities, procedures and controls required to operate sensitive trust services.

Topics may include segregation of duties, traceability, logging, business continuity, monitoring, incident management and cryptographic risk management.

Who I work with

I work with:

• trust service providers;
• organisations wishing to use or integrate trust services;
• electronic signature and digital evidence solution providers;
• security, compliance, legal, product and architecture teams;
• organisations subject to strong requirements for proof, security or compliance.

Example assignments

• Scoping an electronic signature, electronic seal or electronic time stamping project.
• Helping choose between different levels of electronic signature or trust services.
• Analysing the impact of eIDAS / ETSI requirements on an existing architecture or service offering.
• Reviewing policies, practice statements, procedures and audit evidence.
• Designing or evolving a PKI architecture.
• Securing key management and HSM usage.
• Preparing for an audit or qualification.
• Providing expert support to product, architecture, security or pre-sales teams.

Experience

I have over 20 years of experience in software architecture, cryptographic security and the transformation of high-volume critical platforms.

I have contributed to the design, evolution and governance of digital trust services, particularly in the areas of PKI, electronic signatures, electronic seals, time stamping, validation, digital archiving and eIDAS requirements.

My background has led me to work across strategic, regulatory, technical and operational topics: target architecture definition, platform transformation, audit preparation, technical leadership, international team management and expert pre-sales support.

A pragmatic approach

Trust services sit at the intersection of law, security, architecture and business processes.

My approach is to make these topics understandable, auditable and actionable:

1. understand the business need and regulatory context;
2. identify applicable risks, constraints and requirements;
3. define a realistic trajectory;
4. produce clear recommendations;
5. support teams through decision-making, implementation or audit.
