Why every Australian business leader should care about Attack Surface Management

In today’s threat landscape, your organization’s attack surface—every possible point where an attacker could gain access to your systems—is growing faster than ever.

Cloud platforms. Remote work. Shadow IT. Third-party vendors. IoT devices. Each adds new risks that are often unseen or unmonitored—but not to attackers.

This is where Attack Surface Management (ASM)comes in.

What is Attack Surface Management, and Why it matters

Think of ASM as the regular housekeeping of your cybersecurity perimeter. It's a proactive, ongoing process that helps you:

• Discover what assets you have (including forgotten or misconfigured systems),
• Evaluate where the weaknesses are,
• Monitor for changes, and
• Remediate issues before attackers find them.

For a busy CISO or IT lead in a growing business, ASM helps shift your security team from reactive firefighting tostrategic risk reduction.

Why you can’t ignore your Attack Surface

Most SMBs we speak with believe they have a handle on their digital assets—until we show them the dozens of unknown exposures they never realized existed.

Here’s what you risk without ASM:

• Forgotten cloud buckets left wide open
• Unused domains still active
• Unpatched legacy systems exposed to the internet
• Third-party integrations with risky permissions
• Shadow IT tools used by staff without approval

Each of these is a potential door left unlocked. Attackers only need one.

The Payoff: Why ASM is worth your time

Implementing ASM can give you:

• Fewer security incidents and late-night calls,
• Clear visibility across your digital footprint,
• Faster compliance with standards like ISO 27001 or the Australian Essential Eight,
• And most importantly, peace of mind knowing your attack surface isn’t growing out of control.

Actionable steps to reduce your Attack Surface today

Here’s what we recommend for Australian SMBs looking to get serious about ASM:

• Build a Digital Asset Inventory -Include all public-facing systems, cloud services, APIs, endpoints, and domains. Use automation where you can.
• Prioritize Patch Management -Vulnerabilities are often already known. Patch regularly and track versioning across your environment.
• Apply Least Privilege Access -Don’t let staff or contractors access more than they need—especially on admin consoles.
• Segment Your Network -If an attacker gets in, stop them from moving freely. Break networks into secure zones.
• Enforce Secure Configurations -Use benchmarks (e.g., CIS, AWS Well-Architected Framework) to lock down common misconfigs.
• Continuously Monitor for Changes -Track new assets, expired certs, and unauthorized changes. Alerts are only useful if they’re actionable.
• Vet Third-Party Vendors -If they connect to your systems, their risk is your risk. Start with a basic questionnaire or use an automated TPRM tool.
