The Third Wave of Cyber Risk: Why Detection & Response Must Come First.

In today’s digital-first business environment, we often talk about prevention—block the attacks, patch the vulnerabilities, shore up defences. And of course that’s essential. But as the threat landscape evolves, a second truth becomes impossible to ignore: it’s not a matter of if you’ll be targeted, but when.
That change means our collective focus must shift: from preventing every breach, to detecting rapidly and responding effectively.

Here’s why we believe this “third wave” of cyber risk is upon us—and how your business can prepare.

According to the latest review from the Australian Cyber Security Centre (ACSC), Australia’s cyber-threat landscape remains relentless. In FY 2024-25, the ACSC triggered more than 1,700 notifications of potentially malicious cyber activity—an 83 % increase on the previous year. Cyber Security Australia+1
Worse still, the average cost of a cyber incident jumped to approximately A$80,850. Managed Services+1
Which means that as a business you’re no longer operating in a “targeted or not” world — you’re very much in a “when it happens, can you live through it?” world.

Add to that the rise of AI-driven threats — phishing emails written with flawless grammar and personal context, deepfakes that can mimic an executive’s voice or video presence, and supply-chain compromises where attackers target smaller, less-protected partners to infiltrate larger networks.

These developments have fundamentally changed the playing field. The old model of “build higher walls” no longer works when the attack surface now includes your people, your vendors, your cloud services, and even the tools designed to protect you.

In short: prevention remains essential, but it can no longer stand alone as your primary defence. The real edge now lies in early detection, rapid response, and continuous improvement of your security posture.

Imagine two companies. Company A invests heavily in firewalls, patching, anti-virus—but lacks visibility into log data, has no formal incident-response plan and doesn’t train their staff beyond “here’s your password policy”. Company B has similar prevention controls, but also: real-time monitoring, clear escalation procedures, incident-playbooks, frequent tabletop exercises and a culture where “we’ll assume compromise” is a given rather than an exception.

Which company is better positioned when the attacker gets in?
The answer: Company B. Because the cost of a breach is not just the malware—it’s the “dwell time” (how long the attacker is inside), the lateral movement, the cleanup, the reputation damage, the lost productivity. The faster you detect, the smaller the damage and the faster you recover.

Here at Managed Services Australia we emphasise this shift: the “assume breach” mindset. That means building layered defences—but more importantly building detection (logging, threat-hunting, SOC alerting) and response (backups, clear roles, business-impact awareness) into your IT strategy.

If you’re reading this and wondering whether your current setup could handle a real-world incident, you’re asking the right question.

Modern cyber threats don’t just test your technology — they test your visibility, your readiness, and your people. For most organisations, it’s not about whether defences exist, but whether they actually work when it matters.

Many businesses discover too late that what looked secure on paper doesn’t hold up under pressure. Gaps in monitoring, unclear escalation paths, or even a single unaware employee can turn a minor breach into a major event.

That’s why the smartest organisations don’t wait for a wake-up call — they review their detection and response capabilities now.

If you’re not sure where to begin, that’s where we can help. Managed Services Australia works with businesses of all sizes to assess their current posture and build resilience against modern cyber threats.

Your next move shouldn’t be a guess — it should be a conversation.

Being prepared for a cyber event isn’t just about security — it’s about business resilience. When detection and response are built into your operations, the benefits reach far beyond IT:

You build confidence and trust. Clients, partners, and staff see that your organisation takes data protection seriously and can withstand disruption.

You stay compliant and audit-ready. Evolving Australian cybersecurity regulations increasingly expect demonstrable readiness, not just good intentions.

You minimise downtime and financial loss. A rapid, structured response means faster recovery and reduced impact on productivity and revenue.

You gain a competitive edge. In an environment where breaches make headlines, the ability to prove resilience can be a genuine differentiator.

Ultimately, cyber readiness isn’t a cost — it’s an investment in your organisation’s stability, reputation, and future.

Across industries — from legal and professional services to manufacturing and education — one pattern is clear: organisations that assume compromise and prepare to respond outperform those that simply hope to avoid it.

At Managed Services Australia, the focus is on helping businesses build that level of readiness through visibility, rapid response, and a culture of awareness that turns uncertainty into control.
