The Future of Unified SASE – Emerging Use Cases and Success Stories
Secure Access Service Edge (SASE) isn’t just about solving today’s challenges – it’s about being ready for tomorrow’s opportunities. As organisations adopt cloud, AI, IoT and edge computing, the line between networking and security continues to blur. Unified SASE platforms are evolving to meet these new realities.
Macquarie Telecom’s Unified SASE solution with Fortinet is already powering mid-market Australian organisations through complex transformations. Here are the emerging use cases and real customer stories showing how SASE is becoming the foundation for future-ready connectivity and security.
From Zero Trust Network Access (ZTNA) to Universal ZTNA.
The journey from traditional VPN → ZTNA → Universal ZTNA represents SASE’s natural evolution. Universal ZTNA extends granular, identity-based access beyond just users and apps to workloads, containers, OT systems and IoT devices.
What this means practically:
- Secure access to Kubernetes clusters and serverless functions
- Consistent policy for traditional apps, SaaS and custom microservices
- IoT device onboarding without VPN complexity
Australian organisations are already testing these capabilities for manufacturing SCADA (Supervisory Control and Data Acquisition) systems, healthcare telemetry and retail edge analytics.
Adoption trends shaping SASE’s next phase.
Three major trends are accelerating SASE evolution:
1. AI integration
- Real-time threat prediction using AI/ML models across the SASE fabric
- Agent assist for security analysts (similar to contact centre AI)
- Automated policy recommendations based on usage patterns
2. Edge compute expansion
- SASE points-of-presence (PoPs) becoming compute locations for latency-sensitive apps
- Secure app delivery at the edge (e.g. video analytics, AR/VR)
- Branch-to-cloud workload mobility with consistent security
3. IoT security at scale
- Zero Trust for device onboarding and runtime monitoring
- Device segmentation without VLAN complexity
- Automated compliance for regulated industries (healthcare, utilities)
Emerging SASE use cases for Australian organisations.
- Secure Retail Edge
Retailers deploying computer vision at checkout and personalised offers via edge displays need SASE to connect cameras, analytics workloads and central systems securely – without backhauling all video traffic.
- Manufacturing OT convergence
Traditional IT/OT air gaps are disappearing. SASE provides Zero Trust access to PLCs, SCADA and production monitoring while maintaining air-gapped security principles.
- Healthcare device telemetry
Patient monitors, infusion pumps and telehealth endpoints need secure cloud connectivity. Universal ZTNA extends granular access to these devices without exposing entire network segments.
- Multi-cloud workload protection
Development teams spinning up test environments across AWS, Azure and GCP need consistent security policy. SASE follows workloads wherever they run.
Four Australian mid-market success stories.
Customer 1: Regional Logistics (75 sites, 1200 users)
Background: Legacy MPLS + VPN couldn’t support SaaS performance or remote drivers.
Solution: SASE SD-WAN at branches, ZTNA for drivers’ tablets, CASB for Office 365.
Motivation to move: 40% TCO reduction vs MPLS refresh; local MSP operations vs offshore competitors.
Outcome: Driver app performance doubled; security team reduced from 5 to 2 FTEs.
Customer 2: Manufacturing (3 factories, 450 users)
Background: ISDN sunset + need to securely connect production lines to MES/ERP.
Solution: SASE edge with Universal ZTNA for OT systems + FortiEDR endpoint protection.
Motivation to move: Only provider understanding IT/OT convergence requirements.
Outcome: Zero production downtime during migration; first ransomware attack blocked at edge.
Customer 3: Healthcare Network (12 clinics, 800 users)
Background: Telehealth expansion + patient device telemetry security concerns.
Solution: SASE PoP in each state + IoT ZTNA for medical devices + SWG/CASB.
Motivation to move: Australian data sovereignty compliance + healthcare expertise.
Outcome: 3x telehealth capacity; first compliant IoT deployment in network.
Customer 4: Professional Services (8 offices, 600 users)
Background: M&A integration + consultant SaaS sprawl creating security gaps.
Solution: SASE brownfield deployment + FortiAI for threat hunting + CASB Discovery.
Motivation to move: Co-existence strategy preserved acquired firm’s investments during integration.
Outcome: 6-month M&A voice/data integration; shadow IT reduced 70%.
Three conversation starters for your roadmap.
- “Which emerging workloads in our business would benefit most from Universal ZTNA?”
Think IoT, edge analytics, dev/test environments or OT modernisation projects. - “Where are we already converging networking and security today?”
SD-WAN pilots, VPN modernisation or CASB deployments are natural SASE entry points. - “What would our security team do with 30-50% less operational overhead?”
Strategic threat hunting vs daily pipework is a compelling business case.
Questions customers are asking us
“Can we start small and prove value before full commitment?”
Absolutely. Pilots targeting specific user groups, sites or applications build internal support and ROI proof points.
“How does this work with our existing SD-WAN or firewall investments?”
Co-existence is core to our approach – extend policy and visibility while preserving sunk costs during transition.
“What makes Australian mid-market success different from enterprise case studies?”
Limited internal resources make managed services essential. Local expertise navigating vendor ecosystems and compliance is table stakes.
The SASE future is already here – for Australian mid-market.
Unified SASE isn’t theoretical. Australian organisations are already using it to solve IT/OT convergence, secure edge deployments, modernise remote access and integrate M&A environments faster than ever before.
Macquarie Telecom’s Unified SASE with Fortinet combines:
- Platform convergence across SD-WAN, ZTNA, CASB, SWG and NGFW
- Universal ZTNA ready for IoT, edge and containerised workloads
- Proven mid-market deployments with local 24×7 operations
