Cyber Security
Security testing that shows you where you are exposed.
SEDDA’s established testing practice assesses applications, networks, cloud, data, APIs and operational technology to find exploitable weaknesses, validate remediation and give stakeholders clear evidence.
What we test
Practical technical testing across digital and operational environments.
Penetration Testing
Simulated real-world attacks on systems, applications or infrastructure to identify exploitable weaknesses before they are used against you.
Application Security Testing
Checks applications for weak authentication, insecure data handling and unsafe coding practices.
Network and Infrastructure Testing
Assesses servers, network devices and configurations to confirm they are hardened against attack.
Cloud Security Testing
Validates AWS, Azure and other cloud environments against good practice and compliance requirements.
Data Security Testing
Assesses data sensitivity, classification, encryption and retention practices.
API and Integration Testing
Tests APIs and integrations for common vulnerabilities before they can be exploited.
Standards-Based Testing
Security testing aligned to recognised frameworks and standards, with evidence shaped for audit and governance.
Operational Technology Testing
Safe, methodical assessment of ICS, SCADA and production environments, passive or active as the environment allows.
How we help
Flexible support around the security outcome.
Identify risk early
Find weaknesses before they create delivery impact, costly rework or exposure.
Evidence outcomes
Clear findings, risk ratings and remediation evidence for stakeholders and audit.
Retest and validate
Validation of remediation and re-testing, so fixes are proven rather than assumed.
Strengthen capability
Specialists who deliver focused engagements or help develop your own in-house testing capability.
Experience
Security assurance in sensitive operational environments.
Anonymised examples of SEDDA testing work across critical sectors.
Automotive
Mapping risk in a luxury OT environment
Passive operational technology assessment for a luxury car manufacturer in a low-maturity environment, producing prioritised actions to reduce operational downtime.
Outcome: prioritised findings, risk ratings and practical remediation actions.
Power
Securing a substation before go-live
On-site OT penetration testing for a critical national infrastructure operator before connection to the wider network, supporting practical pre-go-live remediation.
Outcome: prioritised findings, risk ratings and practical remediation actions.
Rail
Stress-testing SCADA across rail
Internal penetration testing and protocol fuzzing for a national rail operator to assess SCADA communication resilience and network exposure.
Outcome: prioritised findings, risk ratings and practical remediation actions.
