Senior-Led Engagements for Regulated Organisations

Hands-on support to validate posture, accelerate remediation, and deliver evidence-ready audit outcomes across your security stack.

Phishing Simulation & Awareness

Controlled simulations to measure human risk, drive targeted training, and demonstrate improvement over time.

What we offer:

  • Campaign segmentation, scheduling, and wave management
  • Realistic templates and landing pages aligned to current threat patterns
  • Department-level metrics (open/click/report) with drill-down reporting
  • Optional LMS integration or standalone training modules

Typical deliverables:

  • Campaign dashboard and risk heatmap
  • Leadership-ready executive summary
  • Department remediation actions and follow-up plan

Outcomes:

  • Measurable reduction in risky user behaviour
  • Evidence pack for awareness and audit review

Secure Product Engineering

Security embedded from design through deployment—threat modelling, secure coding, and continuous assurance for production-grade software.

What we offer:

  • Threat modelling and secure architecture review
  • AppSec testing integration (SAST/DAST/SCA) into delivery workflows
  • Hardened CI/CD pipelines and deployment controls
  • Ongoing patching, release governance, and version control practices

Typical deliverables:

  • Threat model documentation and risk register
  • Security test results (SAST/DAST/SCA) with remediation guidance
  • Secure deployment and operations runbook

Outcomes:

  • Reduced vulnerability backlog before release
  • Repeatable security baseline across releases

Penetration Testing

Authorised testing to identify weaknesses before adversaries do—prioritised by exploitability and business impact, with clear remediation paths.

What we offer:

  • Web, API, mobile, infrastructure, and cloud testing scopes
  • Evidence-based findings with proof-of-concept validation
  • Risk-ranked remediation roadmap and secure design recommendations
  • Retesting and closure verification on request

Typical deliverables:

  • Executive summary and technical report
  • Prioritised findings with CVSS and business context
  • Closure pack following remediation validation

Outcomes:

  • Validated control effectiveness
  • Audit-ready penetration test evidence

Data Protection & Compliance Readiness (UK GDPR / KVKK / ISO 27001)

Practical support to align policies, processes, and technical controls—so governance and implementation move together.

What we offer:

  • Gap analysis against target framework and audit expectations
  • Policy and procedure development or review
  • Data classification, access control, logging, and retention alignment
  • Third-party and supplier security assessments

Typical deliverables:

  • Gap analysis report with prioritised action plan
  • Policy pack (data protection, access, retention, incident handling)
  • Control mapping to regulatory/audit requirements

Outcomes:

  • Clear roadmap to audit readiness
  • Documented evidence for regulator or auditor requests

NGFW & Perimeter Security

Firewall architecture, rule-base optimisation, and hardening to reduce exposure at the network edge—from deployment to production tuning.

What we offer:

  • Segmentation, NAT, and rule-base optimisation
  • Threat prevention, URL filtering, and DNS security hardening
  • HA design, performance tuning, and capacity planning
  • Operational runbooks and change management support

Typical deliverables:

  • As-built documentation and policy matrix
  • Hardening checklist with compliance mapping
  • BAU runbook for operations teams

Outcomes:

  • Reduced policy complexity and audit exceptions
  • Production-ready perimeter with documented controls

Security Architecture & Platform Engineering

Design and implement controls that scale—treat security as a product: automated, observable, and sustainable in day-to-day operations.

What we offer:

  • IAM and Zero Trust architecture design
  • SIEM/logging architecture and detection use-case coverage
  • Hardening standards and secure baseline definitions
  • Incident response playbooks and escalation paths

Typical deliverables:

  • Architecture decision records (ADRs)
  • Logging and detection coverage matrix
  • Incident response playbook pack

Outcomes:

  • Scalable security model aligned to business growth
  • Faster mean-time-to-detect and respond

Security Awareness & Role-Based Training

Structured programmes tailored by role and risk profile—measuring impact over time, not just attendance.

What we offer:

  • Role-based curriculum (executive, technical, operational)
  • Simulation integration for reinforcement and behaviour change
  • Periodic assessments and improvement tracking
  • Communication templates and escalation guidance

Typical deliverables:

  • Training plan aligned to organisational risk
  • Progress dashboard (completion, scores, trends)
  • Quarterly executive summary

Outcomes:

  • Demonstrated improvement in awareness metrics
  • Evidence pack for compliance or audit review
