Cyber defence across three layers of maturity
Enterprise cybersecurity is no longer one product or one team - it's a maturity journey from Cyber Fundamentals, through Best Practice, into Next-Generation capabilities. GTP helps clients understand where they stand, identify gaps, prioritise investments, and implement scalable security architectures aligned to enterprise risk and business outcomes.
Why a layered approach matters
Cybersecurity is a fast-moving market - a continuous stream of new threats met by continual innovation that delivers new products and creates entirely new solution categories. For the enterprises GTP serves, the challenge isn't a shortage of tools - it's knowing where to invest, what to consolidate, and which capabilities to mature first.
Whether your organisation is building foundational cyber capabilities, modernising legacy security operations, securing cloud transformation initiatives, or adopting AI safely, GTP provides strategic and operational expertise aligned to enterprise risk and business outcomes.
Our approach helps customers understand cyber maturity, identify security gaps, prioritise investments, and implement scalable, future-ready architectures across three layers: Cyber Fundamentals, Best Practice, and Next Generation.
Defence-in-depth across eight security domains
Our security programmes are built the way modern threats actually move - across layers, not within them. The wheel maps the eight defence-in-depth domains GTP covers, with vendor capabilities GTP delivers in each.
Why a layered cyber programme matters
Enterprise threat exposure isn't shrinking - it's diversifying. The numbers below reflect the operating environment our clients face today.
Indicative industry figures used for planning conversations - actual exposure varies by sector and region.

What security delivery has looked like
Four representative engagements illustrating how GTP turns cybersecurity strategy into operational resilience.
NHS Trust SOC Modernisation
Replaced a fragmented logging estate with a unified Microsoft Sentinel SIEM tied to Trend Vision One XDR. Reduced mean-time-to-detect from days to hours and brought HIPAA-equivalent reporting to a single console.
Zero-Trust Identity Rollout
Deployed Okta Workforce Identity with adaptive MFA and ITDR for a multinational bank - eliminating standing privileges, cutting credential-based incidents, and aligning to PCI-DSS access controls.
OT / IoT Network Segmentation

Common questions about cybersecurity engagements
Where should an organisation start on the maturity journey?
With Cyber Fundamentals - identity, endpoint, and network controls. Most breaches still exploit gaps at this layer. We start with a posture assessment to map current state to the three-layer model.
Do you operate the SOC, or do clients run it themselves?
Both options. We deliver fully-managed 24×7 SOC and MDR services, or stand up your in-house SOC and train your analysts on Microsoft Sentinel, Splunk, Elastic, or QRadar.
How do you secure AI & generative AI workloads?
Through AI governance frameworks, LLM risk assessments, prompt-injection defence, data-loss controls on AI inputs and outputs, and integration with Microsoft Purview, Azure AI Content Safety, and Bedrock guardrails.
Which compliance frameworks do you support?
ISO 27001, SOC 2, GDPR, HIPAA, PCI-DSS, NIST CSF, CIS Controls, Cyber Essentials / Cyber Essentials Plus, NIS2, and DORA - with documented controls and audit-ready evidence.
Can you run a penetration test or red-team exercise?
Yes. We offer authorised pen-testing across web, API, mobile, infrastructure, and cloud, plus full red-team / purple-team exercises mapped to MITRE ATT&CK with detailed remediation playbooks.
How quickly can you respond to an active incident?
Existing managed-service clients get 24×7 incident response with SLA-bound triage. For non-clients we can engage emergency incident response within 24 hours through our retained-IR programme.
