Cyber security transformation

Organisations often take a reactive approach to cyber security, meaning the security function struggles to keep up as the business and technology evolves. A cyber security transformation enables you to rapidly reduce cyber risk and confidently adopt new digital technologies that support your strategic goals.

The challenge for security is growing

Current security models tend to be reactive, with new controls bolted onto inherently insecure legacy IT architecture. This causes an increase in the attack surface and cyber risk exposure.

Cyber transformation enables you to rapidly reduce cyber risk even as your attack surface continues to grow.

Attack surface

Business trend


Supply chain

The extended network is growing, increasing collaboration and joint ventures with business partners to develop digital-centric customer experiences.

More connections with external parties which can be exploited to steal data or disrupt customer services.

Remote working

The workforce is evolving, with more users connected remotely than ever before, anywhere in the world and using any device.

Access and exfiltration of sensitive data due to poorly managed credentials and weak authentication mechanisms.  

Internet of things (IoT)

Organisations are modernising the way they work by adopting internet-enabled devices that can provide telemetry data to support and monitor specific business use cases. 

Use of connected IoT devices increases both the proliferation of unmanaged sensitive data and vulnerability to large scale, multi-vector fifth generation cyber attacks.   

Digital channels

Innovation and redesign of traditional digital platforms are transforming the customer experience, improving the ability to reach new consumers and offer more services online.

More online touchpoints with customers and business partners serving increasingly rich and valuable data which can be targeted to steal or manipulate such data. 


The organisation is accelerating its adoption of public cloud hosted services to improve agility and innovation.

Core business workload is increasingly hosted on cloud infrastructure which, if poorly configured, can be compromised to steal data or disrupt critical services. 

Benefits of cyber security transformation

Reduce risk

Rapidly reduce your exposure to evolving cyber threats which can materially impact your operations and damage your reputation.

Embrace digital with confidence

Secure your new digital assets and the critical customer information they process without slowing down your pace of innovation.

Manage cost

Secure your organisation and protect your customers in an increasingly complex business ecosystem at a price you can afford.

Improve operational resilience

Build a technology enterprise that can withstand cyber attacks or rapid shifts in ways of working without compromising on security.

Our approach to cyber security transformation

Security leaders are under pressure to not only reduce risks now, but also ensure security improvements are sustainable and help prepare their organisation for future threats and opportunities.

Our approach consists of three components:

  1. Rapid risk reduction 
    An agile ‘find & fix’ security workstream leveraging purple team principles starts delivering risk reduction in the first two weeks. Fixes are applied immediately and managed through JIRA workflow. 
  2. Tactical remediation packages
    Due to the complexity of the environment and large IT debt, some of the problems found by the Purple Team are not simple ‘fixes’. This is when a focused tactical time-bound (e.g. 60 day) initiative is required.
  3. Strategic initiatives
    While Purple Team and tactical work packages are ‘fixing backwards’, strategic projects are aimed at addressing the root cause of the issue and building a sustainable capability to ensure the risk is managed.

Transformation mobilisation services

Security assessment

Rapidly assess and benchmark cyber security capabilities, identify gaps, understand exposure to cyber risks, and construct a programme of work to effectively reduce those risks.

Security strategy and business case

Define a forward-looking and sustainable security strategy and roadmap in line with business and IT objectives, covering risk, regulatory, cost, resilience and innovation agendas. 

Security operating model

Define the services, organisation and governance models required to sustain an effective security posture and realise the benefits from a security transformation.

Security architecture

Our security architecture services help organisations build measures that protect their operations while supporting their business goals. Guided by our overarching security architecture framework, our team will support you in the development, review and implementation of security architecture principles, patterns and security design methodologies.

Programme planning

Structure and plan a programme of work that delivers a combination of quick-win tactical enhancements and long term strategic solutions that supports both the cyber security agenda and is sensitive to the needs and capacity for change within the business.

Transformation execution services

Programme management

Define, track and report progress and benefits realised from a cyber security transformation programme.

Rapid risk reduction

Our rapid risk reduction service provides an enhanced approach to purple teaming, combining red team, blue team and technical project management expertise to find and fix security vulnerabilities as soon as they are identified.

Managed cyber defense (MCD)

Our MCD service provides advanced cyber defence against both commodity threats and targeted attacks by focusing around the four key stages of prevention, detection, response and hunting. We provide sophisticated defences across the IT environment (including endpoint, network and cloud) to prevent breaches, reduce cyber risk, support compliance, and help meet the strict breach detection and reporting requirements from regulations such as GDPR and NIS.

Identity and access management

Identity and access management (IAM) provides the foundation of your digital services, governing critical information about people, data and devices.

We can help with all IAM business challenges, including supporting your digital transformation, securing and governing access, enabling a seamless customer experience, and advising on more effective risk-based governance.

Cyber risk management

Identify, quantify and report cyber risk based on three key design principles: business impact, cyber threat landscape and cyber security capabilities.  

Cyber security culture and board awareness

We can help improve cyber security behaviours and transform security culture across your organisation. This includes working with senior leaders to assess their awareness of cyber security and prepare them for how to respond to a potentially high-profile attack. We can also identify and mitigate insecure practices to help reduce cyber risks.

Cyber resilience

Build up the ability to prepare for, respond to and recover from cyber attacks, by defining and shaping security capabilities and controls in modern complex environments.

Benefits of a broader IT Transformation

Cyber security transformation is recommended when your priorities are rapid risk reduction and regulatory compliance. However, a broader IT transformation may be more suitable when there are also other priorities around cost and agility.

During a cyber security transformation, organisations typically adopt new technologies faster than they remove legacy IT. This leads to an increase in the attack surface as there are more systems for attackers to target, along with a continuing increase in security investment to achieve the organisation’s desired level of risk reduction.

There comes a point when there is a compelling case for a broader IT transformation, which enables you to reduce costs and risk by removing legacy IT systems. This makes your organisation inherently more resilient and gives you confidence to focus on innovating your business operations and customer experience.
