Colitus Consultancy Services

IT Security Services Available in London

Cybersecurity, or IT security, is one of the key challenges of the digital society, and calls for an effective combination of design, verification and certification.

In today’s world of cloud computing and increasingly interconnected information systems, including the most critical systems, perimeter based approaches to cybersecurity are no longer sufficient.

At CCS, we believe that the future lies in natively secure solutions, with cybersecurity built into every level — the overall architecture, the network, people and processes and, importantly, the software, especially the application modules used for communications and data encryption.

Since 2002 our consultants have delivered the highest standard of technical and business change consultancy within the field of security.

CCS has been going beyond success and has always been trusted by groups working in the most complex, changeable environments; if you need to succeed in the most demanding contexts.

Cyberattacks can cause the following:

  • Loss of competitiveness
  • Damage to the organisation's reputation
  • Sensitive information leakage
  • Destabilisation
  • Economic paralysis

Cyber Security Risk Assessment and Management

Cyberspace presents a broad range of external and internal threats to your organisation and assets. Following recent high-profile breaches with severe consequences, cyber now heads the risk agenda of many organisations, particularly those within the Critical National Infrastructure.

Our consultants will identify, describe and explain to you those risks which are specific to your industry and your situation. Assets determined to be at risk will be identified and inventoried.

Our team will define what those risks are, work out how likely they are to happen, and assess their impact on your business. Guided by your risk appetite, we will create a risk management strategy, which will determine how you categorise and treat individual risks.

Now that you know and understand the risks you face, we will work with you to develop the business case for addressing them per the risk management strategy. 

Controls are a cornerstone of your defensive strategy. The key challenge is to ensure they do not hinder your organisation or prevent your staff performing their work. Our experienced, multidisciplinary team will review, enhance and replace where necessary existing controls, allowing you to shape and optimise your overall approach and policy.

Digital Transformation

The changing digital and technology landscape in which organisations operate is driving a need to re-assess traditional business models, products and customer relationships. Digital transformation recognises technology and data as core enablers to develop better products, services and customer experiences. Our consultants provide you with a broad and deep perspective across business functions, processes, operations, assets, technology and people, helping you understand and capture the value that digital transformation can bring you, and enabling appropriate risk management from the outset.

Strategy & Architecture

We have been providing thought leadership for over a decade in using evidence base techniques to support the realisation of strategic business change programmes.  We have found a lot of organisations develop a strategy and vision, but do not know how to implement the vision.  Transitioning a business from the current ‘as is’ state to the future ‘to be’ state is complex process.  We use systems thinking and architecture techniques to develop and assess change options. This helps in the understanding of the impact of the change on other business systems and the identification of dependencies, risks and assumption.  Outputs from this service include: Target Operating Model (TOM), architectural models, programme dependencies, risk register, change roadmap and project blueprints.  These outputs can be used to support business case approval and Balance of Investment (BoI) decisions.
