Security Consulting Services

An effective cyber security programme requires strategic planning, governance, policy development and organisational maturity well beyond technology alone. CoreDefence Security Consulting Services strengthen an organisation's cyber security capability holistically, within the NIST Cybersecurity Framework (CSF) v2.0.

Our experts guide you through compliance with international standards and regulations including ISO 27001:2022, PCI DSS v4.0, KVKK, GDPR and the EU NIS2 Directive that came into force in 2025. We stand alongside you across the full process: gap analysis, risk assessment (ISO 27005, NIST SP 800-30), policy development, control implementation, internal audit and certification audit readiness. We also advise on the cyber security obligations of Turkish sector regulators such as BDDK, SPK and EPDK.

Our Zero Trust architecture design service adapts the 'never trust, always verify' principle to your organisation in line with the NIST SP 800-207 Zero Trust Architecture standard. Micro-segmentation, Software-Defined Perimeter (SDP), Continuous Adaptive Risk and Trust Assessment (CARTA) and least privilege combine into a layered defence strategy. We also consult on configuring cloud-based identity management, Zero Trust Network Access (ZTNA) and Secure Access Service Edge (SASE) platforms.

Our cyber risk management service quantifies your organisation's cyber risk using the ISO 31000 and FAIR (Factor Analysis of Information Risk) methodologies. Taking your risk appetite, business impact analysis (BIA) and threat landscape into account, we develop risk treatment strategies and prepare risk dashboards for your board.

We also offer cyber security governance programmes for boards and executive teams, a CISO-as-a-Service engagement, security budget planning, KPI/KRI metric design and strategic roadmap development. Technical assessment and documentation support for cyber insurance applications is available as well.
