Independent cybersecurity consultancy
O&D CYBER
O&D Cyber helps organisations identify exploitable weaknesses, strengthen their security environment, and build capabilities that stand up to real-world threats.

Security for organisations that cannot afford assumptions.
Security expertise across the attack surface
What we do
We test what matters, explain what we find, and help teams decide what to fix next.
Offensive
Controlled testing that shows where an attacker could gain access and what they could reach.
Defensive
Engineering support that turns security signals into detection, response, and resilience.
Cloud
Assessment and hardening for cloud environments, identity, workloads, and trust boundaries.
Strategy
A focused security plan connected to your systems, risk appetite, and business priorities.
GRC
Turn security requirements into practical, measurable controls.
Software
Application security integrated into the way product and engineering teams build.
Incident
Structured investigation and response when a suspected compromise becomes a business priority.
Awareness
Build a security-conscious workforce that can recognise, resist, and report common threats.
Threat Intelligence
Understand your exposure before attackers do — and prioritise what deserves attention first.
Who we work with
Security requirements change with your systems, risk profile, and stage of growth.
Protect applications, APIs, cloud infrastructure, and customer-facing systems.
Assess applications, APIs, identity, infrastructure, and critical systems.
Assess systems and controls where security failures can have significant consequences.
Build security foundations before complexity becomes exposure.
Why O&D
Security should improve decisions, reduce exposure, and give technical teams a clear path forward.
Test assumptions against realistic attack paths, not only checklists.
Support findings with technical evidence, severity, impact, and reproducible context.
Make recommendations practical enough for engineering and operations teams to implement.
Translate technical weaknesses into clear business risk and action.
We test assumptions against how systems fail in the real world.
We leave teams with capabilities they can operate and own.
What you receive
Clear, useful deliverables that help teams decide what to fix and validate the work.
A clear, assessment-ready view of what was found, why it matters, and what to do next.

Our method
Understand objectives, assets, constraints, and threat model.
Map the attack surface, exposed functionality, and trust boundaries.
Validate vulnerabilities through controlled security testing.
Separate theoretical weaknesses from exploitable business risk.
Provide actionable technical remediation guidance.
Validate that identified vulnerabilities have actually been resolved.
From the field
A practical look at where authentication, authorisation, and business logic meet.
Read researchHow to separate configuration noise from the access paths that create real exposure.
Read researchDetection quality is measured by the decisions it enables during a live response.
Read researchProof of work
A demonstration finding — not from a client engagement.
Affected area: /api/accounts/{id}/
Impact: An authenticated user may access another user's resource by manipulating an object identifier.
Remediation: Enforce server-side object-level authorization for every requested resource.
Attack-path analysis
Weaknesses become meaningful when they combine. We help teams understand the sequence from entry point to sensitive resource.
Sample / demonstration
A useful assessment gives leadership a clear view of risk and technical teams a practical remediation path.
