Accountancy firms: prime targets for cyber criminals

Cyber security is no longer optional, especially for accountancy firms. With access to sensitive financial data, personal client information and critical business systems, accountancy practices are prime targets for cyber criminals.

Yet, despite the growing threat landscape, many firms still lack even the most basic protections, including a disaster recovery plan (DRP). That’s a risk no business can afford.

Here’s why you need to act now – and the essential steps to take.

The threat is real and growing

From ransomware attacks to phishing scams and third-party breaches, cyber threats are becoming more frequent, more sophisticated and more damaging. High-profile incidents involving firms like M&S, HubSpot, and MailChimp show that no organisation is too big – or too small – to be targeted.

Accountancy firms, in particular, are vulnerable due to:

  • The volume of sensitive client data they hold
  • Reliance on cloud-based tools and third-party platforms
  • Often limited internal IT resources

7 cyber security essentials every accountancy firm needs

At CSG, we help firms build resilience with a layered, proactive approach to cybersecurity. Here are the non-negotiables:

1. Multi-factor authentication (MFA)

MFA adds a critical layer of protection to your systems by requiring more than just a password. It’s one of the simplest and most effective ways to prevent unauthorised access.

2. Immutable backups

Backups that can’t be altered or deleted by attackers are essential. If ransomware hits, immutable backups ensure you can recover your data – without paying a ransom.

3. Proper cloud backup solutions

Tools like OneDrive are great for syncing, but they’re not true backups. We implement dedicated cloud backup systems that protect your data independently of your live environment.

4. Disaster recovery plans (DRPs)

Shockingly, most accountancy firms still don’t have a disaster recovery plan in place. A well-documented, regularly tested DRP ensures your firm can recover quickly from any disruption – and yes, you should keep a printed copy.

5. Hardware health checks

Don’t wait for a server to fail. Proactive monitoring and replacement of aging hardware can prevent costly downtime and data loss.

6. Staff training & access controls

Human error is one of the leading causes of data breaches. Regular training, clear access policies and a no-blame culture encourage quick reporting and reduce risk.

7. Hosted desktops

Hosted desktop environments offer secure, managed access to key platforms – with built-in updates, backups, and disaster recovery. Ideal for remote and hybrid teams.

No DRP? You’re not alone – but that needs to change

Most businesses admit they don’t have a disaster recovery plan. That’s a major vulnerability – but also a clear opportunity to take action.

A DRP isn’t just a technical document. It’s your business continuity lifeline in the face of cyberattacks, hardware failures or natural disasters.
