Cyber Incident Exercising
Proven NCSC-assured exercising.
At Avella, we help organisations prepare for the worst — and respond with confidence when it matters most.
NCSC-assured cyber exercises that prepare your team for the moments that matter most.
Our Cyber Incident Exercising services have been assured by the National Cyber Security Centre (NCSC) under their Cyber Incident Exercising (CIE) scheme, demonstrating our commitment to the highest standards of quality, realism, and operational value.
Why Cyber Incident Exercising Matters?
Cyber incident exercising tests your readiness, uncovers gaps, and ensures your teams can respond swiftly, effectively, and in line with best practice.
Test today. Protect tomorrow.
In today’s threat landscape, cyber attacks are not a question of if, but when. Exercising helps you test your organisation’s readiness, refine your response plans, and strengthen coordination across technical, operational, and executive teams.
Reveal risks. Refine your response.
Our exercises expose real-world vulnerabilities, sharpen decision-making under pressure, and ensure that your incident response processes align to best practice, regulatory, and stakeholder expectations.
Our approach
Avella’s exercises are designed to be realistic, relevant, and actionable. Every engagement is carefully tailored to your sector, systems, and threat profile, ensuring that every scenario feels authentic and directly applicable. We offer a range of exercise formats, including:
Tabletop Exercises (TTX)
Strategic and operational decision-making drills for organisations and leadership teams.
Live Play Exercises
Simulated real-time attacks to test detection, response, and escalation across teams.
