Information Security Consultant (CISO, Divestment)

Candidates must engage via an FCSA accredited Umbrella company and will be required onsite approximately 2 days per week in Edinburgh.

In addition to prior InfoSec divestment experience, candidates should have a broad and deep understanding of application segregation and separation, identity and access management separation (including Active Directory / Entra ID separation) and a strong understanding of data management and information risk (including data classification and handling during migration, data transfer, duplication, decommissioning risks, and data leakage during transition).

The successful candidate will be responsible for helping to advise and guide on a separation & divestment portfolio, assessing & challenging technical designs, translating technical security risk into clear advice for projects teams and identifying, detailing and prioritising real security risks in imperfect transitional states rather than aiming for theoretical target-state purity.

• Proven experience supporting IT divestment, separation, carve-out or M&A programmes, with direct involvement in technical and architectural security decisions
• Strong, practical understanding of application segregation and separation, including access control models, authentication and authorisation separation, data boundary definition, and transitional/shared service risks
• Strong, practical understanding of identity and access management separation, including Active Directory / Entra ID separation, tenant and domain separation, and identity lifecycle and residual access risks
• Strong understanding of data management and information risk, including data classification and handling during migration, data transfer, duplication, decommissioning risks, and data leakage during transition
• Ability to assess and challenge technical designs produced by architects and engineers, not just review them at a high level
• Ability to identify, describe, and prioritise real security risks in imperfect transitional states rather than aiming for theoretical target-state purity
• Ability to translate technical security risk into clear, actionable advice for programme and project teams
• Strong analytical, communication, and problem-solving skills
• Hands-on advisory experience across cloud environments, particularly AWS accounts, IAM, network and trust boundary separation, and shared services
• Experience engaging directly with enterprise applications, including SaaS, on-prem, and hybrid solutions
• Practical understanding of privileged access management in separation scenarios
• Experience contributing to or drafting risk assessments, security positions, and exception recommendations
