Cyber Security and Resilience Services

Cyber Security Advisory Services

Technical responders focus on containing and recovering from an incident. Senior leaders face an entirely different challenge: making strategic decisions under pressure.

During a major cyber event, organisations may need to communicate with employees, customers, regulators, insurers, investors, suppliers, and the media while managing legal, operational, reputational, and security considerations.

GSA provides cyber security advisory services directly to:

• Boards and Non-Executive Directors
• CEOs and Executive Committees
• Crisis Management Teams
• General Counsel and Risk Leaders

We support decision-making, governance, escalation, stakeholder management, regulatory engagement, and cross-functional coordination throughout a live incident.

Our role complements technical incident response providers, ensuring leadership remains focused, informed, and in control.

Cyber Resilience Readiness Assessment

A Cyber Resilience Readiness Assessment provides a clear view of your organisation’s ability to prevent, withstand, respond to, and recover from a serious cyber incident.

Our independent cyber security risk assessment examines:

• Cyber threat exposure
• Governance and oversight
• Leadership and decision-making readiness
• Cyber security monitoring and incident response arrangements
• Recovery and business continuity capabilities
• Regulatory obligations and reporting requirements
• Critical operational dependencies

Rather than a compliance-focused exercise, the assessment delivers a practical evaluation of resilience and identifies priority areas for improvement.

Ideal for boards, executive teams, CISOs, risk leaders, and organisations seeking an independent assessment of cyber resilience.

Cyber Lifeboat & Minimum Viable Operations Planning

When a significant cyber incident occurs, organisations must know which business functions are critical to survival and how they will continue operating if key systems become unavailable.

GSA’s Cyber Lifeboat methodology helps organisations identify:

• Minimum viable operations
• Critical business activities
• Essential systems and data
• Key dependencies and third-party reliance
• Recovery priorities and sequencing
• Leadership decision points during disruption

The outcome is a practical operating model that supports continuity through severe cyber disruption, including offline workarounds, recovery procedures, backup validation, and clean recovery environments.

Our objective is simple: ensure your organisation can keep operating when normal systems and processes fail.

Cyber Crisis Exercising Services

A cyber incident response plan is only effective if it works under real-world pressure. Cyber crisis exercising helps organisations test decision making, escalation, communication, recovery and governance before a real incident occurs.

GSA designs and delivers realistic cyber crisis exercises that test:

• Leadership decision-making
• Crisis governance
• Incident escalation processes
• Internal and external communications
• Regulatory response
• Business continuity and recovery capabilities

Exercises can include:

• Tabletop simulations
• Executive leadership exercises
• Technical recovery scenarios
• Full-scale crisis simulations
• Annual exercising programmes

Each crisis exercise is designed to challenge assumptions, identify vulnerabilities, and strengthen organisational resilience.

Counterintelligence-Informed Cyber Threat Assessment

Understanding who may target your organisation is as important as understanding how they operate.

GSA’s Counterintelligence-Informed Cyber Threat Assessments provide insight into potential adversaries, their motivations, capabilities, and likely attack methods.

Assessments may include:

• Threat actor profiling
• Insider threat analysis
• Supply chain and third-party risk
• Hostile state activity
• Sector-specific threat exposure
• Strategic intelligence assessments

This service is particularly valuable for organisations operating in critical infrastructure, financial services, professional services, technology, government, defence-related environments, and family offices.

Cyber Regulatory Incident Reporting Support

Cyber incidents increasingly trigger legal, regulatory, contractual, and insurance-related reporting obligations.

GSA helps organisations prepare for and manage these requirements by supporting:

• Reporting and notification procedures
• Governance and decision-making frameworks
• Leadership preparedness
• Regulatory engagement
• Information flow and escalation processes
• Incident reporting readiness

By establishing clear responsibilities and reporting protocols before an incident occurs, organisations can respond quickly and confidently when reporting deadlines arise.

Cyber Investigations & Crisis Management

Not every cyber incident is purely technical.

Many incidents involve wider concerns such as insider activity, fraud, data misuse, organised crime, reputational damage, physical security risks, or potential litigation.

GSA provides a multidisciplinary approach that combines:

• Cyber expertise
• Investigations capability
• Intelligence analysis
• Crisis management
• Protective security experience

Where required, cyber engagements can be integrated with corporate investigations, insider risk programmes, due diligence, surveillance, security vetting, and broader crisis response activities.

This ensures organisations can address the full impact of an incident, not just the technical breach.
