Why trusted cyber protection is critical now
UK cyber threats are intensifying
The scale and severity of attacks continues to escalate with a 129% surge in 'nationally significant' cyber attacks year-on-year1.
Attacks carry escalating costs
The average cost of a significant cyber attack has climbed to nearly £195,000, contributing to £14.7 billion in annual losses across the economy each year2.
Human-led risks dominate
Phishing remains the primary entry point for attackers, with 85% of breached UK organisations reporting phishing as the initial cause2.
