Ransomware: The reality for your business

Ransomware isn’t just a big business problem anymore

When people hear “ransomware”, they often picture large businesses making headlines.

Small businesses are now one of the most common targets, not because they’re careless, but because they’re often easier to disrupt and more likely to pay to get back up and running quickly.

“The UK Government’s Cyber Security Breaches Survey 2025 found that around 50% of businesses experienced a cyber attack or breach in the last year, rising to 70% for medium-sized organisations.”

Ransomware isn’t just about files being locked.

Modern attacks are more strategic and often follow a pattern:

  1. Access

    An attacker gains entry, often through a compromised password, phishing email, or unpatched system.

  2. Silent movement

    They don’t act straight away. Instead, they explore the environment, identify valuable data, and understand how your systems work.

  3. Data extraction

    Sensitive data is often copied before anything is locked.

  4. Encryption and disruption

    Systems and files are locked, bringing operations to a halt.

  5. The demand

    A payment is requested, often with the added pressure that stolen data will be leaked if ignored.

The real impact on a business

The financial cost is only part of the story.

Ransomware can lead to:

  • Operational downtime - teams unable to work

  • Loss of client trust - especially if data is exposed

  • Regulatory implications - depending on the type of data involved

  • Internal disruption - stress, uncertainty, and lost productivity

Common misconceptions

“We’re too small to be targeted” Most attacks are automated. Size doesn’t protect you.

“We have antivirus, so we’re covered” Traditional tools alone are no longer enough.

“We have backups, so we’re safe” Backups are important, but only if they are secure, isolated, and tested.

What actually reduces risk

There’s no single solution, but a combination of practical steps makes a significant difference:

1. Strong access control

  • Multi-Factor Authentication (MFA) on key systems

  • Secure password practices

2. Regular patching and updates

  • Keeping systems up to date closes known vulnerabilities

3. Backup strategy (and testing)

  • Backups should be:

    • Regular

    • Stored securely (ideally offsite or immutable)

    • Tested to ensure they can be restored quickly

4. User awareness

  • Many attacks still start with a simple action

  • Creating a culture where people feel comfortable questioning things is key

5. Monitoring and early detection

  • The earlier unusual behaviour is spotted, the more chance there is to stop an attack before it escalates

What actually reduces risk?

Being prepared, most successful attacks don’t happen because a business has done something wrong. They happen because small gaps exist across systems, processes, and people.

Closing those gaps doesn’t require drastic change, just the right controls, reviewed regularly.

If you’re unsure where you stand

A good starting point is simply asking:

  • Could we recover our systems quickly if we had to?

  • Are we confident in who has access to what?

  • When did we last review our security setup?

If those questions are difficult to answer, it may be a good time to speak with an expert at Roadmap who can help you with a review.
