CDD Philosophy

Honesty and Quality

CDD can be relied upon to be completely open, discrete and honest in all matters, and at all times, and with all clients.  

CDD will provide the highest attainable quality of service to all its clients  and at all times.  

CDD's consultants are security cleared to high levels, being vital for the conduct of technical services and interaction within departments of His Majesty's Government. 

Ethics and Aesthetics

CDD will combine systems ethics and operational aesthetics to deliver the highest attainable levels of applicability and usability of security capability. 

The CDD culture of innovation ensures attainment of bleeding-edge security engineering.

The approach to technological development at CDD is radically different, relying upon the innate creativity and combination of mindsets of developers both young and older.


CDD will endeavour to ensure that all services are performed with maximum, or optimized efficiency. 

CDD will ensure that there will never be any occassion where nugatory or unnecessary services will ever be undertaken and will provide the leanest possible capability necessary to achieve the stated requirement(s).


Green Credentials

CDD has invested in the use of a 'POWERSTATION' that derives energy from photovoltaic cells which can be utilised under normal operations and in an emergency capacity.   

For the purpose of normal administration and research, CDD uses very capable laptop and mini computers configured to utilise minimal, yet optimum power and centralised local data storage (as opposed to cloud storage) to maximise security and minimise power consumption arising from distributed storage utilization.  

CDD deploys centralised grid computation centered upon Apple architectures.  



CDD recently augmented the firm’s grid super-computing capability by utilisation of ultra-low power multi-core systems that achieve the highest possible processing speed, efficiency and applicability for the lowest possible power demands and 'cost of ownership' profile.

This is especially important for preparation of CDD's heavily recursive, high density NN-ML-AI processing that underpins security applications development and other research. These processing approaches have been interwoven into CDD's cyber essentials operational methodology.


Innovative Culture 

CDD promotes and applies a culture of continuous directed innovation with clarity and volition, enhancing process with specific objectives and products that meet realistic and entirely feasible requirements.

CDD properly enables creative conceptualisation within cybersecurity that gives rise to increased value within organisations and associated rewards for those (clients) capable of such realisation. 

CDD is examining the most efficacious development and deployment of advanced machine learning, neural networks and augmented human cognition(AI) to a range of technical problem spaces. 

CDD and HMG ITEPA(2003) Legislation 
- IR35 - 

The business does not engage in consultative or development assignments that are deemed to be encompassed by Off-Payroll Working Rules (OPWR) and would be pleased to provide a full, metricated Status Determination Statement that demonstrates the facts around CDD Operations and Governance Structures (CDD_OGS). 

Propspective clients can therefore engage with complete and total confidence of full compliance with HMRC's taxation measures, outside IR35 rules. 

CDD working practices are described in a single contract that combines one or more assignments, each encompassing one or more work packages that have clear deliverables, time scales, a technical approach, description of processes, reporting processes, time planning and resource allocation, quality controls and payment terms.

These provide the basis of CDD's business model and any possible interpretation of linkage within our development or consultative practices that might suggest IR35 non-compliance will result in immediate review and suitable adjustment; failing that, possible revocation and rescinding of any such arrangements.

CDD is frequenly approached to undertake work that is alleged to have some determinable IR35 status.  An SDS must be provided to support such assertion prior to any consideration of engagement.

CDD Ethics (Machine Learning Models)
--- Nine Areas Under Construction ---
Readers will appreciate that these are very complex areas of requirements definition, demanding extremely close attention to detail as we prepare and discover techniques and design associated data management to comply with such rules as we design below.  Our PEDDLE adjunct to PASCAL (the PRINCE2 DevMeth) is being adjusted to accommodate these extremely difficult areas of Quality Assurance.  

Accuracy, Recursion and Explanation 


Algorithmically Constrained Generalisation 


Composition Control, Scale-elasticity and Chrono-metrics and Audit


Interoperability and Transparency


Legacy Architecture and Interoperability 


Legal Liability, Accountability and Responsibility 


Limitation and Adaptation 


Model Security, Trustworthiness and Reparation
