Cyber security in 2025: What we learned and how to stay ahead in 2026

Why human factors, AI, and compliance will define the next era of cyber defence

2025 was a turning point for cyber security. From headline-grabbing breaches to the rise of AI-driven attacks, businesses faced unprecedented challenges. So, what can you learn - and how can you prepare for what’s coming?  

We recently hosted a panel webinar that discussed just that. Watch the recording for the full insights and discussion, and hear from experts from Sophos and KnowBe4. 

Don’t have time to watch the full recording? Take a look at the key takeaways below. 

Key lessons from 2025

• Technology alone isn’t enough - People, processes, and preparation matter just as much. 

• Social engineering is the attacker’s weapon of choice - Human behaviour is the biggest vulnerability. 

• AI is a double-edged sword - It’s powering both defence and attack. 

• Speed is critical - Rapid detection and response can make or break your recovery. 

• Compliance is tightening - Frameworks now demand regular, meaningful security training. 

• Emerging risks are here - Deepfakes, shadow AI tools, and multi-channel attacks will dominate 2026. 

Why people are the weakest link

Cybercriminals exploit human nature - urgency, trust, and routine. They target new hires, mimic senior leaders, and time attacks for when employees are least alert. It’s easier to trick someone into handing over access than to break through hardened systems. 

AI: Friend and foe

Attackers use AI to craft convincing phishing campaigns and automate reconnaissance. Defenders use it to detect anomalies and accelerate incident response. But AI isn’t a silver bullet - you still need skilled analysts and robust processes. 

Compliance and training: no Longer optional

Frameworks like Cyber Essentials, ISO, PCI DSS, and DORA now require ongoing training and phishing simulations. Staying compliant protects your reputation and reduces risk. 

Looking ahead to 2026

• Multi-channel attacks across email, SMS, Teams, Slack, and LinkedIn. 

• Supply chain vulnerabilities targeting smaller vendors. 

• Deepfakes and voice impersonation making fraud harder to detect. 

• Shadow AI tools creating uncontrolled data exposure.
