APRA CPS 234: What It Means for Your Business in 2025

Imagine this: you’re a board member of a super fund, or the CEO of a health insurer. Everything seems to be ticking along… until the phone rings. A ransomware attack has locked down your systems. Sensitive customer data might be exposed. Regulators are demanding answers. Now what?

That’s the scenario APRA CPS 234 is designed to prevent — and today, we’re unpacking what it really means for Australian businesses and why it matters more than ever in 2025.

Welcome to the Don’t Be A Sitting Duck Podcast, I’m Leigh Kefford—let’s dive in.

Let’s start with the basics: what is CPS 234?

CPS 234 is a mandatory cybersecurity standard enforced by APRA — that’s the Australian Prudential Regulation Authority. It came into effect back in July 2019, and it applies to banks, insurers, superannuation trustees, and health funds.

Its purpose? To make sure that any organisation handling Australians’ financial or personal information has the right systems, processes, and governance in place to protect those assets.

It’s not just about ticking boxes. It’s about protecting people’s savings, investments, medical records, and retirement income from increasingly aggressive cyber threats.

How It Happened & Why It Matters

CPS 234 came off the back of a string of data breaches and cybersecurity failures in Australia and globally. It was clear — many institutions weren’t prepared. APRA’s response was simple but firm: Cybersecurity must be embedded at the core of your business — not outsourced, not siloed, not ignored.

What’s unique about CPS 234 is that it puts accountability right at the top — with your board of directors. That means:

• • Your board is responsible for the entity’s overall information security posture.
  • They must be informed, involved, and ready to act on risk.
  • And when something goes wrong — they need to be ready to report and remediate fast.

It’s not just an IT thing anymore — it’s a governance thing.

Now let’s break it down further…

Key Requirements of CPS 234

CPS 234 requires organisations to do a few core things — and do them well:

1. 1. Clearly define information security roles and responsibilities. Everyone from the board to the IT team must know what they’re accountable for when it comes to protecting information assets.
   2. Maintain an appropriate information security capability. This means having enough skilled people, effective tools, and smart processes to protect against threats that are relevant to the size and nature of your business.
   3. Implement and test security controls. These aren’t just firewalls and antivirus software — it includes employee training, monitoring tools, response plans, and even third-party risk assessments.
   4. Report serious incidents. If a cyber event affects customer data, disrupts operations, or has the potential to do so — you must notify APRA within 72 hours. That’s a tight window, especially if you’re scrambling.
   5. Review and test regularly. Just having a plan on paper isn’t enough. You need to prove it works. That means running simulations, reviewing results, and adjusting where needed — just like fire drills.

Why Should You Care (Even If You’re Not a Bank)?

Even if your business isn’t regulated by APRA, this standard sets a gold benchmark for governance. It answers a critical question: Can your organisation recover from a cyberattack without falling apart?

Many SMEs and non-profits are adopting CPS 234 as a best practice framework. Why? Because it gives you structure. It turns cybersecurity from a vague IT task into a measurable business priority.

Take Action – What You Can Do Today

If you’re unsure where your organisation stands with CPS 234 or general cyber preparedness, here are five actions you can take right now:

1. 1. Audit your information assets.
      Know what data you have, where it lives, and how critical it is to your business.
   2. Assess third-party risks.
      Who hosts your data? Cloud vendors? IT providers? You’re still responsible if they get breached.
   3. Review your incident response plan.
      Have a step-by-step plan — and test it annually. Include who calls who, when, and how.
   4. Get the board involved.
      Make sure cybersecurity is a standing item in board meetings — with metrics, updates, and funding.
   5. Schedule an external security assessment.
      A third-party checkup can identify blind spots before attackers do. At National PC, we offer an independent review of your systems with ability for CREST Certified Penetration Testing.

Here’s the thing: no business is bulletproof. But with the right people, process, and technology — you don’t have to be a sitting duck either.

CPS 234 is more than a compliance requirement — it’s a blueprint for resilience.
