Visibility
Better visibility of cyber and resilience risk.
Prepare for GCAP with Secure, Governed APIs
Help Your Organisation Demonstrate Measurable Cyber Accountability
The Government Cyber Action Plan (GCAP) has raised the bar for cyber resilience across UK government organisations.
Arm’s Length Bodies are expected to demonstrate clear accountability, measurable risk management and improved visibility across digital services.
For many organisations, the biggest visibility gap sits in the integration layer, where APIs connect systems, data and partners.
Without governance across these connections, it becomes difficult to demonstrate the control and evidence GCAP requires.
Azure API Management (APIM) provides a practical way to improve visibility, security and governance to this critical layer.
TXP helps public sector organisations implement APIM to strengthen cyber resilience and support GCAP readiness.
How TXP Can Help
In a recent TXP engagement we delivered:
40%
Faster Release Cycles
99.5%
SLA Compliance
TXP works with government organisations and Arm’s Length Bodies to design and implement secure, observable and governable API platforms using Azure API Management.
Our approach helps organisations quickly improve visibility across their integration estate while strengthening cyber resilience.
In one recent TXP engagement, implementing Azure API Management reduced release cycle times by 40% while improving SLA compliance to 99.5%.
Why GCAP Makes API Governance Critical
GCAP focuses on four key outcomes:
Threat Management
Stronger capability to manage complex threats.
Response Speed
Faster response to cyber incidents.
Resilience
Rapid improvement in government-wide resilience.
Most digital services depend on APIs and system integrations to move data and connect platforms.
These integrations are often the least visible part of the digital estate, making them difficult to govern or monitor.
Without consistent API governance, organisations can struggle to:
• Track how data moves between systems
• Detect failures or abnormal behaviour
• Enforce consistent security policies
• Provide audit evidence for cyber assurance
Improving visibility and control across APIs can significantly strengthen an organisation’s ability to meet GCAP expectations.
How Azure API Management Supports GCAP Outcomes
Azure API Management helps organisations support these outcomes by providing:
Centralised Visibility
Monitor API usage, failures and dependencies through detailed analytics and telemetry. This helps organisations identify risk, understand service behaviour and improve operational oversight.
Consistent Security Policies
Enforce authentication, access control, rate limiting and payload validation through reusable policies. This ensures security standards are applied consistently across all APIs.
Controlled Change Management
Track API versions, manage revisions and deploy updates safely with clear audit trails. This supports measurable governance and helps organisations demonstrate controlled change processes.
Integration with Cyber Monitoring
Send structured logs and telemetry to SIEM and SOC platforms, supporting cyber monitoring and enabling faster detection of operational or security issues.
What Good Looks Like
Organisations preparing for GCAP should aim to establish:
- A complete inventory of APIs and integrations
- Consistent API security and governance policies
- Monitoring dashboards for integration health
- Clear audit trails for API changes and deployments
- Executive-level visibility of integration risk
This creates the measurable accountability GCAP expects organisations to demonstrate.

FAQs
What is GCAP and why does it matter for Arm’s Length Bodies?
The Government Cyber Action Plan (GCAP) is a UK government initiative designed to strengthen cyber resilience across departments and Arm’s Length Bodies.
It requires organisations to demonstrate measurable accountability for cyber risk, including improved visibility across digital services, stronger governance and faster response to cyber incidents.
For ALBs, this means being able to monitor, measure and report on cyber risk across systems and integrations, rather than relying solely on traditional perimeter security.
Why are APIs important for GCAP compliance?
APIs are now the primary way systems communicate across modern digital services.
They connect internal applications, legacy platforms, cloud services, external suppliers and data platforms.
Because of this, APIs often carry sensitive data and critical service interactions. Without visibility and governance across APIs, organisations may struggle to demonstrate the accountability and monitoring required under GCAP.
How does Azure API Management help support GCAP objectives?
Azure API Management provides a central platform to govern APIs and integration points.
It helps organisations:
• Monitor API usage and operational health
• Enforce consistent security policies
• Maintain version control and change governance
• Generate telemetry and logs for cyber monitoring platforms
These capabilities improve visibility and control across integrations, helping organisations demonstrate measurable cyber accountability.
Do we need to replace existing systems to implement API governance?
No. Azure API Management typically sits in front of existing services, acting as a secure gateway for API traffic.
This allows organisations to introduce governance, monitoring and security controls without needing to replace legacy systems.
In many cases, APIM is used to stabilise legacy services while providing modern operational visibility.
What are the main benefits of adopting API governance?
Organisations that introduce structured API governance often see improvements in:
• Visibility across system integrations
• Security policy consistency
• Operational monitoring and incident response
• Release governance and change control
• Service reliability and performance
These improvements help strengthen cyber resilience while also supporting faster and safer digital delivery.
How quickly can organisations improve their API governance?
Many improvements can be made relatively quickly once the integration landscape is understood.
A typical starting point is an API discovery and governance assessment, which identifies existing integrations, risks and visibility gaps.
From there, organisations can implement Azure API Management incrementally, beginning with the most critical services.
What is involved in the TXP API Governance and GCAP Readiness Assessment?
TXP’s assessment helps organisations understand their current integration landscape and identify opportunities to strengthen governance.
The assessment typically includes:
• Discovery of APIs and system integrations
• Review of security and governance practices
• Identification of visibility and monitoring gaps
• Alignment with GCAP objectives
• A practical roadmap for implementing Azure API Management
This provides a clear starting point for improving cyber visibility and resilience.
When should organisations start preparing for GCAP?
GCAP Phase 1 runs until March 2027, but organisations are expected to show measurable progress toward improved cyber resilience.
Starting early allows organisations to introduce governance changes in a controlled way, rather than making rushed changes closer to compliance deadlines.
Improving visibility across APIs and integrations is often one of the fastest ways to demonstrate meaningful progress.
