Build a security framework that’s ready for tomorrow

Today, digital infrastructure underpins every physical supply chain, customer journey, and operational process. When systems are intertwined this deeply, weak foundations ripple fast. A robust security architecture ensures your digital backbone can evolve, absorb shocks, and enable opportunity, not inhibit it.

At Littlefish Group, our architecture team blends deep technical design expertise with lived experience from leaders of some of the world’s most complex transformations. These are practitioners who’ve built and operated large-scale systems, learned from failure as well as success, and know what it takes to make resilience real. Working with your teams, they bring discipline, foresight, and pragmatism, helping you build security that’s both grounded and growth-ready.

Cutting through the complexity with confidence

    Seeing the whole system

    Architecture isn’t about spotting flaws, it’s about seeing how the system behaves as a whole. We expose interdependencies, not just weaknesses, showing where design decisions create resilience, agility, or risk. These insights let you strengthen your architecture before pressure hits.

  • “Since Littlefish have been appointed, they have been consistently delivering really excellent service to our staff. We have really tough expectations and have a sliding scale approach to customer satisfaction, so as the years go on, it gets harder. I’m really pleased to report that Littlefish have consistently met this scale.”
    Rob Langley
    Chief Information Officer, Cafcass
  • “It made sense to us to go to an organisation that could offer us a range of security services… we chose Littlefish because they could provide everything we needed. In an ever-evolving landscape, there’s always more to learn and new threats emerging, so I’m confident that Littlefish can help us with that.”
    Amanda Hodge
    ICT Manager
  • “We don’t see Littlefish as an ‘at arm’s length’ organisation, but as a partnership that works closely with us and that’s really important. We’ve really had great engagement in how they wish to understand our unique business and the way we operate and we’re starting to really reap the rewards of that engagement now.”
    Nigel Hall
    Director of IT and Analytics
  • “Throughout the tender process it really did become obvious that Littlefish put customer service at the heart of their approach and were willing to get to know the Canal & River Trust as an organisation. Since go live the positive feedback has been overwhelmingly unanimous from across the organisation which reinforces the belief we have chosen the right partner.”
    James Myhill
    Head of IT, Canal & River Trust
  • “We trust Littlefish to work closely with us and move processes along and remove the need for constant firefighting when it comes to mitigating cyber security risks. Littlefish helped us put our priorities in place and reach a level of security I’m 100% happy with.”

Strategic security delivered with confidence

Deep-dive risk mapping

No auditing from the sidelines here. We embed with your teams, using structured walk-throughs, reference architectures, and control-effectiveness testing to deliver a risk map that leads directly to a design roadmap. This includes priorities, costed options, and quick-win actions that you can implement immediately.


Architects who still build

Our senior architects are hands-on professionals who still enjoy opening a console. They treat architecture as a craft, not a career step. Their experience across decades of large-scale transformation gives you pragmatic guidance born from real design decisions, trade-offs, and lessons learned under pressure.


Adaptive evolution

We’ve modelled an approach that keeps architecture alive, continuously aligning controls, integrations, and guardrails with changing business priorities. By combining reference blueprints with feedback from live operations, we ensure your design evolves safely with technology, regulation, and growth.
