Big Breaches. Familiar Risks.

When HMRC confirmed that nearly £49 million had been lost in a phishing scam affecting around 100,000 taxpayer accounts, it made headlines. Shortly after, M&S, Co-op, and Harrods faced major cyberattacks that disrupted operations, exposed data, and cost millions.

These weren’t isolated or highly advanced attacks. In each case, criminals exploited common gaps—stolen passwords, phishing emails, weak identity checks, and supply chain vulnerabilities. It shows how even the most well-resourced organisations can be caught off guard.

If you’re a smaller business without an in-house IT team, it can be hard to know where to start. But that doesn’t mean you’re helpless.

We Work with Businesses Facing the Same Questions

We support businesses that know cybersecurity matters – but are often unsure where their biggest risks are, or what steps are worth prioritising.

You don’t need a big budget or complex systems. What you do need is a clear plan and consistent protection.

What Went Wrong – and Why It Matters to SMEs

Here’s what we’ve learned from recent attacks:

  • Phishing and Credential Theft: The HMRC scam relied on fake emails and stolen personal data to create or hijack accounts. M&S and Co-op were breached after attackers tricked staff into sharing credentials.
  • Third-Party and Supply Chain Risk: M&S was targeted through a supplier. Many SMEs are part of wider supply chains – often without assessing their own exposure.
  • Lack of Multi-Factor Authentication (MFA): In several cases, MFA could have stopped the attackers even after a password was compromised.
  • No Incident Response Plan: Downtime, delays, and confusion followed. Many businesses don’t know what to do when something goes wrong.
  • Underinvestment in Basics: Co-op had no cyber insurance in place. M&S had insurance but still reported £300 million in losses.

What You Can Do – Starting Today

Cybersecurity doesn’t have to be overwhelming. These steps can make a meaningful difference:

  • Train your staff
    Phishing is still the most common attack method. Regular training helps your team spot and report threats early.
  • Turn on MFA everywhere
    Multi-factor authentication is one of the simplest, most effective ways to stop account breaches.
  • Patch and update your systems
    Most attacks rely on old vulnerabilities. Keeping systems updated closes the door on known exploits.
  • Back up your data
    Automated, secure backups (with offsite copies) ensure you can recover quickly if hit by ransomware or system failure.
  • Have a response plan
    Know what to do, who to contact, and how to limit damage. Test the plan before you need it.
  • Consider cyber insurance
    It won’t prevent an attack, but it can limit the financial impact and help you recover faster.
