My name is Chloe and I am in charge of all things marketing at Nebula. I started as an apprentice at the start of January 2024, and completed a degree in Graphic Design previously. Outside of work, I love everything to do with motorsports – I try and attend car shows and events as much as possible. Aside from this, I find that being out in nature and walking is very beneficial and allows me to have some time away from the screens.

The UK government’s latest Cybersecurity Breaches Survey revealed that 43% of businesses suffered a cyberattack or data breach in the past year. Medium and large businesses were particularly affected.

Phishing attacks — where attackers trick people into revealing personal or financial information — were the most common.

💸 The average cost of the most serious attacks:

  • £1,600 for businesses
  • £3,240 for charities

Why this matters:

Cyberattacks can be expensive, disruptive, and damaging to reputation. As the threat continues to grow, it’s more important than ever to take action — whether you’re a business, charity, or individual.

✅ Simple recommendations worth knowing

For Businesses:

  • Train your team: Help staff recognise phishing emails and suspicious activity. People are your first line of defence.
  • Use the right tools: Install good antivirus software and set up systems that can detect and block threats.
  • Back up important files: Save copies of your data in safe, offline places to protect against ransomware attacks.
  • Have a plan: Prepare a clear, step-by-step response plan so you can act quickly if something goes wrong.

For Charities:

  • Don’t underestimate the risk: Even smaller organisations can be targets. Set aside budget for basic cybersecurity protections.
  • Ask for help: Look to government resources or specialist charities for guidance tailored to your size and sector.

For Individuals:

  • Use different passwords for different accounts. One hacked password shouldn’t unlock everything.
  • Keep an eye on your accounts: Check your bank and online accounts regularly for anything unusual or suspicious.
