Secure Solution Engineering

At Espanaro, secure solution engineering is core to everything we do. 

The experienced team at Espanaro design, develop, test and deploy secure systems for the defence, security and manufacturing sectors. This critical discipline ensures that these systems are protected from a variety of threats, including cyber-attacks, physical attacks, and human error.

Espanaro’s secure solution engineering typically involves the following steps:

  1. Threat modelling - identifying and understanding the threats that a system may face. This includes both external threats, such as cyber-attacks, and internal threats, such as human error or malicious action. A threat matrix is commonly developed in conjunction with key stakeholders to ensure all threat vectors are covered.

  2. Risk assessment - assessing the likelihood and impact of each threat vector. This helps to prioritize the security controls that need to be implemented.

  3. Design - ensuring the secure system solution in a way that mitigates the identified threats. This may involve implementing security controls, such as firewalls, intrusion detection systems, and access control lists or complete system redesigns – from system architecture onwards. Additionally, Data Centric Security methodologies are core to Espanaro’s experience and design ethos.

  4. Development - building systems in accordance with the security design and deliverables. This includes implementing the security architectures, infrastructure and controls along with testing the system for security vulnerabilities.

  5. Deployment - releasing the system in a secure manner. This includes configuring the security controls and monitoring the system for security events, alongside pre- and post-deployment testing and quality assurance.

  6. Operation and maintenance - ensuring the day-to-day operations and regular maintenance of the secure system are undertaken correctly, in the short, medium and long-term.  This includes updating the security controls and responding to security incidents.

Secure solution engineering is a complex and challenging discipline, but it is essential for protecting the defence, security and manufacturing sectors from varied and ever-changing threats.


By following the steps outlined above, Espanaro and their client organisations can develop and deploy secure solutions that protect their critical assets – at pace and on budget.

Here are some additional considerations for secure solution engineering in the defence and security sectors:

  • The need for continuous improvement - the threat landscape is constantly evolving, so it is important to continuously improve the security of defence and security solutions. This includes regularly reviewing the threat model, risk assessment, and security design.

  • The importance of collaboration - secure solution engineering is a team effort. It requires collaboration between engineers, security experts, and end users.

  • The need for a culture of security - a culture of security is essential for the successful implementation of secure solution engineering. This means that everyone in the organisation, from the CEO to the front-line staff, must understand the importance of security and be committed to protecting the organisation's assets.

By following these principles, Espanaro and client organisations can develop and deploy secure solutions that protect their critical assets and meet the ever-evolving threat landscape.
