What we deliver

Security built in from day one

In today's rapidly evolving threat landscape, organisations need more than reactive security measures. Secure by Design is a proactive approach that integrates security principles throughout your capabilities lifecycle—from initial strategy through design, development, deployment, ongoing operation and disposal.

We work closely with organisations to ensure security is embedded from the outset. Whether you're developing new systems, procuring technology, or looking to implement a Secure by Desing framework into an existing capability, our experienced consultants provide the specialist expertise you need to build secure, compliant, and resilient technology.

Soteria can help align to Secure by Design frameworks and standards that apply to your sector. Whether that's the Cross-Government Secure by Design Framework and GovAssure for central government, JSP 440, 453 and Def Stan 05-138 for defence, the NCSC Cyber Assessment Framework or IEC 62443 for critical national infrastructure, or ISO 27001 and Cyber Essentials for the wider private sector.

Security Strategy & Requirements

We work with you to define security strategies aligned with your business objectives. Our consultants help you establish clear security requirements, risk appetite, and success criteria—ensuring security supports rather than hinders your goals.

Secure Design & Architecture

Our consultants ensure security is embedded into system design from the outset. We help you make informed decisions about security controls, design patterns, and technical approaches that reduce risk whilst maintaining operational efficiency.

Threat Modelling & Risk Assessment

Using proven methodologies, we help you identify potential threats, assess risks to your systems, and prioritise mitigation strategies. Our pragmatic, contextualised approach, ensures you focus resources where they matter most.

Vendor & Supply Chain Security

From procurement through to ongoing vendor management, we help you evaluate security capabilities, define contractual obligations, and manage third-party risk. We ensure your supply chain isn’t an unknown risk.

Threat Modelling & Risk Assessment

We provide independent security assurance throughout your technology lifecycle. Our consultants conduct design reviews, assess security controls, and provide advice on risk decisions.

Compliance & Regulatory Support

Our team guides you through complex regulatory requirements, policies and frameworks such as JSP 440, JSP 453, NCSC CAF, IEC 62443, GDPR, ISO 27001. We help you understand obligations and implement practical solutions.

Security Testing Coordination

We help you establish appropriate security testing regimes, working with specialist testing partners where required. We ensure testing is proportionate, well-scoped, and delivers actionable insights.

Secure Development Guidance

We provide guidance on secure development practices, helping you establish processes and standards that embed security throughout the development lifecycle—without creating unnecessary overhead.

FAQs

Explore some of the questions regularly asked about this service. Have a question not covered here? Get in touch.

What is Secure by Design?

Secure by Design is an approach where security is integrated throughout the technology lifecycle—from initial strategy through design, development, operation and disposal, rather than added as a final layer. It ensures capabilities are inherently resilient and secure by default.

We don't have security expertise in-house. Can you help?

Absolutely. Many of our clients don't have dedicated security teams. We provide the specialist expertise you need—working with your existing stakeholders, building capability where appropriate, and acting as your security partner.

Do you work with our existing suppliers and partners?

Yes. We work collaboratively with your suppliers, development partners, and internal teams. Our role is to provide independent security expertise and ensure the right security outcomes are achieved.

How is this different from security testing?

Secure by Design focuses on embedding security from the outset—preventing issues before they arise. Security testing identifies issues after systems are built. Both are important, but our approach significantly reduces what needs to be fixed later.

What regulations or policies does this address?

We help organisations meet UK PSTI Act, GDPR, ISO 27001, IEC 62443, NCSC CAF, JSP 440 and 456, Cross-Government Secure by Design Framework and GovAssure. We translate legal, regulatory and policy complexity into practical action.

Can you support projects already underway?

Yes. Whilst engaging early is ideal, we regularly support in-flight capabilities. We assess current security posture, identify risks and gaps, and provide practical recommendations to improve security outcomes.

What if we're procuring technology rather than building it?

We have extensive experience supporting procurement. We help you evaluate vendor security capabilities, define contractual security obligations, and ensure vendors deliver secure systems that meet your requirements.

How long does engagement typically last?

Engagement length varies based on project scope. Initial engagements typically run 8–12 weeks, though many clients retain us for ongoing advisory support as technology and requirements evolve.

Do you replace our internal teams?

No. We work alongside your existing teams, providing specialist security expertise and building internal capability. Our goal is to strengthen your security posture—not create dependency.

How do you measure success?

Success is measured through contextualised risk, regulatory compliance, informed decision-making, and security outcomes that support business objectives. We establish clear success criteria aligned with your goals at the outset.
