Security Architecture Implementation

Making ESA happen in the real world

DLC’S approach to enterprise security architecture (ESA) Implementation is about making ESA happen and using it to meet dynamic cybersecurity challenges. Inevitably, this involves changing the organisation by introducing new, and updating old, risk management concepts, perspectives, and activities. These changes touch and impact, both directly and indirectly, many parts of the organisation.  Change is difficult and failing to effectively manage organisational change is, in some estimates, the single biggest factor in the failure of information and technology projects. Resistant to change is the norm. Even when the benefits of security architecture implementation are clearly understood, implementing changes and making the changes stick are not easy. Our team of consultants, including an organisational change consultant, help clients negotiate the complex challenges to effectively integrate ESA into client organisations.


Successful ESA implementation delivers value through enterprise security that demonstrably enables the organisation’s pursuit of goals and objectives in the present and, as the organisation evolves, into the future.


The power of ESA is that security resources and solutions work holistically with all elements of the organisation in pursuit of business goals and objectives. Implementation deploys the designed ESA into the enterprise. Deployment requires aligning and integrating security architecture artefacts and processes into relevant enterprise processes, including Security, IT, Enterprise Risk Management, Audit, and business units. Others impacted usually include HR, procurement, and supply chain functions.

Implementation includes organisational change and, to some extent, process re-engineering, to:

  • Assess organisational change readiness
  • Identify relevant organisation units
  • Align ESA artefacts and activities to impacted processes
  • Integrate ESA artefacts and activities into impacted process


Successful ESA implementation transitions ESA designs into operations to realize business-enabling benefits. Alignment, integration and adoption of an ESA Framework the organization to:

  • Adapt, integrate, and align existing Enterprise frameworks, methods and standards Expand application of your business- driven approach enterprise wide
  • Demonstrate a measurable contribution from security to business performance targets and risk appetite
  • Achieve cohesion between functions by achieving end-to-end and through life integration with EA, Quality, Governance, Risk and Compliance, Service Management,  Security Operations, Business Continuity, Process Engineering, Project Management, and Physical Security
