Attack-focused assessments
We test how systems actually fail — validating attack paths, not just theoretical weaknesses.
Independent cybersecurity consultancy
O&D CYBER
Security that holds up when tested.
We test applications, infrastructure, cloud environments, and security controls to identify exploitable weaknesses before attackers do — and help engineering and security teams fix them.

How we work
Built around evidence, not assumptions.
Evidence-backed findings
Every finding is supported by technical evidence, impact analysis, remediation guidance, and retesting where applicable.
Engineering-focused remediation
Guidance is written for the engineers who fix the problem, not just the report that describes it.
Business-aware risk analysis
Every finding is tied to the operational and business impact it creates, not just a severity score.
Security for organisations that cannot afford assumptions.

How we can help
Engagements organised the way you buy security.
Five categories, not a list of forty capabilities. Each one is a service you can scope and request directly.

- Cloud penetration testing
- Adversary simulation
Defensive
Defensive Security
Operational and engineering support that turns security signals into detection, response, and resilience.
- Security monitoring
- Detection engineering
- Incident response
- Infrastructure hardening
- Vulnerability management
Engineering
Security Engineering
Application and cloud security built into the way engineering teams design and ship software.
- Secure software development

Awareness
Security Awareness
Build a security-conscious workforce that can recognise, resist, and report common threats.
- Security awareness training
- Staff security training
- Phishing simulations
Who we help
Built for teams with something worth protecting.
Technology & SaaS
Designed for teams that need to secure applications, APIs, and cloud infrastructure as they scale.
Financial Services
Designed for organisations that need rigorous testing of applications, identity, and critical infrastructure.
Government & Public Sector
Designed for public sector technology teams that need independent, evidence-based security assessments.
SMEs Handling Sensitive Data
Designed for smaller organisations that hold sensitive data but don't have an in-house security team.
Organisations Preparing for Compliance
Designed for teams preparing for ISO 27001 or other regulatory and compliance requirements.
Teams Launching or Changing an Application
Designed for teams shipping a new application or making significant changes to an existing one.
Why O&D Cyber
An approach that's hard to copy.
Anyone can claim to be attack-minded or evidence-driven. Here is what that actually means when we work.
Attack-minded
We don't stop at identifying a theoretical weakness. We determine whether it can be chained into a meaningful attack path.
Evidence-driven
Findings include reproducible technical evidence, severity, business impact, remediation guidance, and retest status.
Engineering-focused
Recommendations should be implementable by the engineers responsible for fixing the problem.
Business-aware
Technical severity is translated into the operational and business consequences that matter to decision-makers.
What you get
Concrete artifacts, not a verbal opinion.
Every engagement ends with something your team can act on and your leadership can read.

How an engagement works
A clear process, from first conversation to retest.
01
Discovery
We understand your environment, objectives, scope, and risk concerns.
02
Assessment
We test the agreed attack surface using a structured methodology.
03
Evidence
We validate findings and determine practical exploitability and impact.
04
Reporting
You receive technical findings and an executive-level summary.
05
Remediation
We provide prioritised, implementable remediation guidance.
06
Retest
Where included, we validate that identified issues have been addressed.

Notes for better security.
Writing detections that support an investigation
Detection quality is measured by the decisions it enables during a live response.

A sample, anonymised finding — not from a client engagement.
WEB APPLICATIONHIGH
IDOR / Broken Object Level Authorization
Affected endpoint: /api/accounts/{id}/
Attack scenario: An authenticated user changes the numeric account identifier in an API request and retrieves another user's account data without authorisation.
GET /api/accounts/4821/profileHTTP/1.1 200 OK{ "account_id": 4821, "owner": "other-user" }
Business impact: Any authenticated user could enumerate and access other customers' account data — a reportable data exposure.
Remediation: Enforce server-side object-level authorization for every requested resource.
