Frequently Asked Questions

Got a question you need answering? Our FAQs should help guide you

Yes, the EU AI Act was formally adopted in May 2024 and entered into force on 1 August 2024. However, different provisions apply at different times. Prohibitions on unacceptable-risk AI systems took effect in February 2025, while high-risk system requirements become fully enforceable from August 2027.

The EU AI Act does not directly apply to the UK post-Brexit. However, UK businesses deploying AI systems that affect EU residents or selling AI products into the EU market must comply with the Act. The UK is developing its own AI regulatory framework, but currently follows a sector-specific approach rather than comprehensive legislation.

The Act primarily regulates AI systems placed on the EU market or whose outputs are used within the EU. If an AI system is deployed outside the EU but processes data or produces decisions affecting individuals physically located in the EU, compliance obligations may apply. The Act's territorial scope mirrors GDPR's extraterritorial reach.

Recent research reveals that the average breach now costs $4.35 million, with global cybercrime expenses projected to surge by 23% annually. By 2027, these costs could reach a staggering $23.84 trillion per year. This alarming trend underscores the critical need for robust cybersecurity measures.

Penetration testing is a vital cyber security solution. As cyber attacks grow more sophisticated and frequent, proactive testing of your defences becomes even more important. Safeguard against potential breaches and avoid devastating financial impacts. Implementing pentesting services is no longer optional – it’s a necessity for many businesses seeking to protect their assets and reputation.
