SEDDA combines specialist cyber security expertise with independent technology and AI assurance, helping organisations understand risk, validate controls and make informed decisions.
Our capabilities
Cyber Security
Established security testing across applications, networks, cloud, data, APIs and operational technology, with remediation validated and evidenced.
Independent Assurance
Objective, evidence-based assessment of technology, programmes, suppliers and controls, separate from delivery, to support informed risk and governance decisions.
AI Assurance
An independent, evidence-led view of the AI running across your organisation: where the risk is, how it measures against recognised standards and what to do about it.

Our approach
A structured approach to assurance.
Every engagement starts with the decision you need to make and the consequence of getting it wrong. Scope and depth follow from that, not from a fixed catalogue, and findings are reported for both executive and technical audiences.
01
Discover
Understand context, requirements and relevant risks.
02
Assess
Apply specialist expertise to systems, technologies and controls.
03
Evidence
Establish clear and objective findings.
04
Advise
Inform decisions, priorities and subsequent action.
Let’s talk
Discuss your assurance requirements.
Whether you need specialist cyber security expertise, independent technology assurance or guidance on emerging AI risks, SEDDA can help you assess the challenge.
