2025 taught us some valuable lessons about cybersecurity. Most importantly, considering attacks on Co-op and JLR, anyone can be impacted - regardless of size. Cybersecurity is now a board issue, not an IT problem. In 2026, the biggest risks will get even harder to ignore—they’ll come from believable scams, weak supplier controls, and employees who unknowingly open the wrong link. For UK company directors, understanding where the threats are moving is essential to protect revenue, reputation, and insurance coverage.
Here are the top 5 cybersecurity trends in 2026, ranked by business impact—with the threats you’ll likely face and the practical steps that actually work.

The threat: Artificial intelligence is making scams frighteningly convincing. Fraudsters can now clone voices and faces, creating fake calls, emails or videos that look and sound exactly like a senior member of your team. We’ll see more “urgent” payment requests that appear genuine—and more businesses losing money before they realise what happened.
How to protect your business:
Always double-check payment changes by phone, using a number you already know.
Enforce multi-factor authentication (MFA) for systems that hold money or data.
Train staff using realistic scam simulations, not just tick-box e-learning.
Make it normal for employees to challenge requests, even from senior staff.
This will be the number one cyber risk for SMEs in 2026—because AI is making old scams almost impossible to spot by eye.
The threat: Criminals are moving away from “hacking systems” and instead focusing on hacking people. They steal login details, trick staff into approving access requests, or exploit weak passwords to get into company accounts. Once they’re in, they can move across your systems and even impersonate your staff online.
How to protect your business:
Switch to passwordless login options where possible (such as fingerprint or face ID).
Use MFA across every key system—email, finance, HR, customer data.
Review who has access to what every few months and remove old accounts quickly.
Teach staff to spot suspicious login requests or approval prompts.
Think of it like a key: if someone copies it, they own your building. In 2026, the “keys” to your digital world are your people’s identities.
The threat: Most SMEs now run dozens of cloud services—accounting software, CRMs, HR tools, file-sharing apps and more. Each one contains sensitive data, but few companies track who has access or what’s connected to what. A single weak link in one of these apps can open the door to everything else.
How to protect your business:
Keep an up-to-date list of every app your business uses.
Restrict data sharing between systems to only what’s necessary.
Make sure ex-employees lose access to all systems the day they leave.
Choose suppliers who clearly explain their security and data protection measures.
In 2026, this “SaaS sprawl” will be one of the biggest blind spots for SMEs—because your data now lives everywhere.
The threat: Ransomware—the malware that locks or steals data—won’t go away. But it’s evolving. Criminals are now threatening to publish stolen information or destroy systems entirely if a ransom isn’t paid. Even businesses with backups can face weeks of downtime and damaged reputations.
How to protect your business:
Keep offline backups that can’t be tampered with, and test restoring them regularly.
Make sure critical systems are isolated from the rest of the network.
Work with a provider that offers 24/7 monitoring, even outside office hours.
Create a clear incident response plan—who to call, what to say, and what to prioritise.
This is less about paying ransoms and more about how quickly you can recover. In 2026, resilience will define who survives an attack and who doesn’t.
The threat: Regulators, insurers, and even customers are raising the bar. Expect stricter reporting timelines after a breach, and cyber insurance policies that demand proof of strong controls before they’ll pay out—or even offer cover.
How to protect your business:
Align to a recognised standard like ISO 27001 or the NCSC Cyber Essentials.
Keep a simple risk register and review it with the board quarterly.
Run at least one cyber incident rehearsal each year.
Make sure your insurance broker understands your controls and coverage gaps.
Compliance is becoming a business enabler. The better your evidence of control, the easier it is to win contracts and renew insurance.
