Protect your business from ransomware, phishing and data breaches with layered cyber security aligned to the ACSC Essential Eight.
Cyber security for business is the layered protection of your people, devices, identities and data against threats like ransomware and phishing. Tech Hub Australia delivers managed cyber security to Sydney SMBs — Essential Eight uplift, Microsoft Defender, multi-factor authentication and Zero Trust access — assessing your posture, closing gaps and defending you around the clock.
Cyber threats do not discriminate by company size. Small and medium businesses are now among the most common targets precisely because they are often under-protected — attackers automate their campaigns and hit whoever is vulnerable. A single click on a convincing phishing email, or one reused password, can become a business-ending event: encrypted files, a drained bank account, or a notifiable data breach.
Tech Hub Australia builds layered defences around the things that matter — your people, your devices, your identities and your data — so no single failure brings the business down. We assess your current posture, close the gaps in priority order, and then maintain those defences over time with endpoint detection and response, email security, multi-factor authentication, disciplined patching and ongoing security awareness training for your staff.
Everything we do is mapped to the ACSC Essential Eight, the baseline recommended by the Australian Signals Directorate, and delivered through a Zero Trust approach using the Microsoft security stack most Sydney businesses already own.
Assess and uplift your maturity against the ACSC Essential Eight — the baseline every Australian business should meet — with a clear plan to reach your target maturity level.
Microsoft Defender for Endpoint on every device to detect, isolate and remediate threats in real time, with alerts triaged by our team.
Microsoft Defender for Office 365 filtering and anti-phishing to stop the email-borne attacks that cause the majority of breaches.
Turn your team into a human firewall with ongoing training and simulated phishing campaigns that build lasting good habits.
Multi-factor authentication and Entra ID conditional access to verify every login and lock down identities across Microsoft 365 and beyond.
Practical help meeting NDIS, Privacy Act and industry compliance obligations with clear evidence, reporting and documented controls.
The Essential Eight is the ACSC's prioritised list of eight mitigation strategies that, implemented together, make it much harder for common attacks to succeed. Maturity is measured from Level Zero (weakest) to Level Three (strongest). For a plain-English walkthrough, read our guide to the Essential Eight explained for Australian business.
Good security is not about buying more products — it is about implementing the right controls well and maintaining them. We focus on the fundamentals that stop the attacks businesses actually face, and we prove it with clear reporting against the Essential Eight.
Traditional security trusted anyone inside the office network. With cloud apps and remote work, that perimeter no longer exists. Zero Trust verifies every request instead.
| Consideration | Zero Trust | Perimeter model |
|---|---|---|
| Default trust | Never trust, always verify | Trusts anyone inside the network |
| Identity checks | Every login, with MFA | Once, at the firewall |
| Remote work fit | Designed for cloud and hybrid | Assumes staff are in the office |
| Device health | Enforced via Intune compliance | Rarely checked |
| Breach containment | Least privilege limits spread | Flat access aids lateral movement |
We benchmark your current posture against the Essential Eight, reviewing identities, endpoints, email, backups and policies.
You get a plain-English report ranking risks by likelihood and impact, with a costed, staged uplift roadmap.
We deploy MFA, conditional access, Defender and hardening, and enable tested backups — closing the highest-risk gaps first.
We maintain your defences, triage alerts, run awareness training and report on your posture as threats evolve.
We build security on the platforms you already own, so protection is integrated rather than bolted on. Identity and access are governed by Microsoft Entra ID with conditional access and MFA; threats on devices are detected and contained by Microsoft Defender for Endpoint; email is protected by Microsoft Defender for Office 365; and device compliance is enforced through Microsoft Intune. This integrated approach is what makes practical Zero Trust achievable for a small business.
Endpoint and email threat protection with managed alerting.
Identity, MFA and conditional access enforcing Zero Trust.
Device compliance and hardening policies across your fleet.
Tested, immutable backups so you can recover after an incident.
We work with sectors that carry real security and compliance weight — NDIS and disability providers handling sensitive participant data, healthcare practices, professional services firms, not-for-profits and manufacturers. Each gets controls matched to its obligations. See our industries we serve and case studies for context.
As an illustrative, anonymised example: an NDIS provider we work with needed to demonstrate that participant records were protected. We rolled out MFA across all accounts, enforced Entra ID conditional access, and produced Essential Eight evidence they could show to auditors and funders — turning a compliance worry into a documented strength.
The Essential Eight is a set of eight baseline mitigation strategies from the Australian Cyber Security Centre (ACSC): application control, patch applications, configure Microsoft Office macro settings, user application hardening, restrict administrative privileges, patch operating systems, multi-factor authentication and regular backups. Each is measured across maturity levels zero to three. We assess your current maturity and help you uplift it pragmatically.
Yes. Attackers automate their campaigns and target whoever is vulnerable, not who is famous. Small and medium businesses are frequently hit precisely because they assume they're too small to matter and under-invest in security, making them easier to compromise than a hardened enterprise.
Zero Trust is a security model that assumes no user or device is trusted by default, even inside your network. Every access request is verified explicitly using identity, device health and context, and users are granted only the minimum access they need. In a Microsoft environment this is delivered through Entra ID conditional access, MFA and device compliance policies in Intune.
Yes. Our cyber security assessment reviews your endpoints, identities, email, backups and policies against the Essential Eight, then gives you a clear, prioritised report of risks and fixes. You can book one as part of a free IT assessment.
We build on the Microsoft security stack — Microsoft Defender for Endpoint for threat detection and response, Microsoft Entra ID for identity and multi-factor authentication, conditional access for Zero Trust enforcement, and Microsoft Defender for Office 365 for email and phishing protection — complemented by security awareness training and managed backup.
We can assist with incident response and recovery, contain the threat, restore from clean backups, and then put the controls in place to prevent a recurrence. The best time to act, though, is before an incident — get in touch for a posture review.
