Specialist Programme Support
Major programmes, digital transformations, and acquisitions generate security requirements that cannot be met by existing security teams alone. The scale, pace, and complexity of programme delivery demand dedicated cyber security expertise that operates within the programme structure - not as an external review function that arrives late and adds constraints without context.
London Strategy Centre provides cyber security expertise embedded within programmes, ensuring security is considered throughout delivery - from requirements definition through to system design, assurance documentation, and post-deployment review.
Security added late to programmes creates cost, delay, and residual risk
The pattern is consistent across sectors: a programme progresses through business case, procurement, design, and build phases with limited security involvement. When security review is introduced - often triggered by an assurance gate or compliance requirement - it identifies architectural decisions that are expensive to change, requirements that were not captured, and risks that should have been managed from the outset.
The result is rework, delay, and accepted residual risk that a structured security workstream would have prevented. The earlier security expertise is embedded in a programme, the lower the cost and the stronger the outcome.
Five areas of specialist programme support
LSC provides cyber security expertise across the programme lifecycle - from inception through to operational handover and beyond.
Cyber Support for Major Programmes
Embeds security expertise within programme structures to ensure cyber security is considered throughout project delivery. This is not a review function - it is a delivery function. Security specialists work alongside programme teams, participating in design decisions, attending governance meetings, and providing security input that is timely, contextual, and practical.
Secure System Design
Ensures new platforms and systems are built with strong security architecture from the outset. Working from threat models and security requirements, LSC supports the design of systems where security controls are structural rather than compensatory - integrated into data flows, access models, and network architecture rather than layered on after the design is fixed.
Security Requirements Definition
Ensures that projects and procurements incorporate appropriate security controls from the specification stage. Clear, testable security requirements - defined before procurement decisions are made - prevent the common failure of discovering security gaps after a contract has been awarded or a system has been built.
Assurance Documentation
Provides the evidence of security compliance required for audits, programme gates, regulatory reviews, and customer assurance. Documentation is produced as a natural output of structured security practice - not as a retrospective exercise. This includes risk assessments, security design documentation, test evidence, and compliance mapping against relevant frameworks.
Cyber Due Diligence for Mergers and Acquisitions
Cyber security due diligence for mergers, acquisitions, and major technology change programmes.Identifies security risks associated with acquisitions, mergers, or partnerships. Due diligence assessments evaluate the target organisation's security posture, technical vulnerabilities, governance maturity, regulatory compliance, and outstanding risks - providing the acquiring organisation with a clear picture of cyber risk that informs valuation, negotiation, and integration planning.
Embedded expertise delivers better outcomes than external review
The distinction between embedded programme support and external security review is significant. External reviews assess a programme at a point in time, they identify issues but do not shape the decisions that created them. Embedded support operates within the programme, influencing design decisions as they are made and ensuring security considerations are weighed alongside cost, schedule, and functionality. This approach reduces the volume and severity of findings at assurance gates, lowers the cost of security compliance, and produces systems that are genuinely secure rather than retrospectively hardened.
Who this is for
These services are designed for programme directors managing large-scale delivery with security requirements, digital transformation teams building new platforms or migrating legacy systems, M&A teams requiring cyber risk assessment as part of due diligence, defence and government programme teams with formal assurance requirements, and organisations where existing security teams lack capacity for dedicated programme support.
Frequently Asked Questions
From the outset. Security requirements defined late in a programme are more expensive, more disruptive, and less effective. LSC recommends integrating security input during the requirements and design phases.
Yes. LSC provides independent technical authority input to major system design and procurement decisions — providing assurance that security requirements are proportionate, implementable, and aligned to the programme's risk profile.
LSC produces security assurance cases, risk management frameworks, statement of applicable controls, security aspects letters, and accreditation documentation for government and defence programmes.
Yes. LSC conducts cyber security due diligence for mergers and acquisitions, identifying security risks in target organisations and providing structured findings that inform deal terms and post-merger remediation planning.
