A multi-site branch operations group modernised secure access across sites, users and cloud applications
A multi-site branch operations group needed to modernise the way users accessed business applications, Microsoft 365, cloud services and internal systems across a distributed operating environment. The existing access model had grown around fixed sites, traditional network controls, remote access pathways and practical operational requirements. It had supported the business, but the environment had become more distributed, more cloud-dependent and more identity-driven.
Inlight IT helped design and deploy a SASE-aligned secure access model, improving policy consistency, remote access, traffic visibility, identity-aware access control and operational support across the organisation.

Multi-site branch operations — SASE deployment and secure access modernisation
Identity-aware secure access across branches, remote users and cloud applications for a distributed organisation.
Secure access delivered as architecture, not platform
Access decisions follow identity, device context, application requirements and traffic behaviour, not just IP address or network segment.
Branches, offices, remote users and cloud applications supported through one consistent secure pathway.
Microsoft 365 and cloud applications reached through direct, secure access pathways with appropriate inspection and policy.
The deployment left an operating model support teams could monitor, operate and improve over time.
SASE is not a product category to be switched on — it is secure access architecture designed around the way the organisation works
The organisation operated across multiple locations with users relying on a mix of site-based systems, cloud applications, Microsoft 365, remote access and internal resources. Like many distributed branch operations businesses, the network and security environment had evolved over time — branch connectivity, firewall rules, VPN access, cloud adoption, identity controls, application access and user support had all developed around real business needs.
That model had worked, but it was becoming harder to scale and manage. Users needed reliable access from different locations. Security policies needed to be more consistent. Remote access needed to be easier to control. Network visibility needed to improve. Microsoft 365 and cloud applications needed a secure access model that did not rely only on traditional perimeter controls.
The objective was to move toward a more modern access architecture: identity-aware, policy-driven, cloud-ready and easier to operate across a multi-site environment.
The organisation needed to modernise secure access without creating disruption across sites, users and operational workflows
This was not simply a firewall replacement or a new remote access tool. SASE affects how users connect, how traffic is inspected, how cloud applications are accessed, how policies are applied and how support teams troubleshoot access issues. For a multi-site organisation, access problems quickly become operational problems.
Secure access needed to work across all user locations
Users worked from offices, branches, remote locations and mobile contexts. The access model needed to support all of them through a more consistent secure pathway, not a patchwork of VPN, site-bound controls and cloud-specific exceptions.
Security policy needed consistency across the environment
Different sites had developed different access patterns over time. Policy drift creates risk. The deployment needed a model where security controls could be applied consistently across users, locations, cloud applications and traffic types.
Identity needed to drive access decisions
A traditional perimeter model assumes users and applications sit behind predictable locations. That assumption no longer reflects how the organisation operated. Access decisions needed to follow identity, device context, application requirements and traffic behaviour, not just IP address or network segment.
Microsoft 365 and cloud applications needed secure access pathways
Cloud-bound traffic patterns are not well served by routing everything back through a central firewall. Microsoft 365, SaaS applications and cloud services needed direct, secure access pathways with appropriate inspection and policy.
The model had to remain supportable after deployment
If users cannot reach applications, branches lose productivity. If remote access is difficult to manage, support overhead grows. If visibility is poor, troubleshooting and incident response become harder. The deployment needed to leave an environment support teams could operate.
Five operational layers connecting SASE architecture, identity, connectivity, security policy and operational handover
Inlight IT helped the organisation design and deploy a SASE-aligned secure access model across the operating environment. The work connected network architecture, identity, cloud access, branch connectivity, endpoint access, security policy and managed support into a more scalable model.
01SASE architecture and deployment planning
The work began by mapping how the organisation actually operated, not by selecting a platform. Existing network, access pathways, users, sites, applications and security dependencies were mapped so the deployment reflected the real operating environment, not a generic reference architecture.
02Identity-aware secure access
SASE is strongest when access policy is connected to identity. Inlight IT helped align secure access controls with user identity, role, location, device posture and application requirements for a more granular access model than traditional network-based controls.
03Branch, remote user and cloud connectivity
Inlight IT supported the deployment of connectivity pathways that improved access to Microsoft 365, cloud applications and internal systems while maintaining security controls, moving the organisation away from a purely site-bound access model.
04Security policy and traffic control
A SASE deployment needs clear security policy design — otherwise it becomes another access layer without consistent control. Inlight IT helped structure security policy across users, locations, applications and traffic types.
05Operational handover and managed support
Inlight IT helped transition the SASE environment into an operating model that could be monitored, supported and improved over time, with deployment validation and policy refinement built into the handover.
From access-pattern mapping to a deployment that landed in a supportable operating model
Select a stage to trace how the deployment moved from access mapping to managed operation.
A perimeter model assumes users and applications sit behind predictable locations — that no longer reflects how many organisations operate
Users work from multiple places. Applications sit in Microsoft 365, cloud platforms and internal environments. Security controls need to follow identity, device context, application access and traffic behaviour. For a multi-site branch operations group, inconsistency compounds quickly: different sites develop different access patterns, remote access becomes harder to manage, policies drift, troubleshooting becomes slower and support teams lose visibility.
Five operational layers connected SASE architecture, identity, connectivity, security policy and operational handover.
One consistent secure access model replaced a patchwork of VPN, site-bound controls and cloud-specific exceptions.
Different sites develop different access patterns over time — policy drift creates risk, and inconsistency compounds quickly across a multi-site environment.
Each visibility or policy gap creates either a security risk or an operational drag — and often both.
The organisation gained a more modern secure access architecture across users, sites, cloud applications and internal systems
The deployment improved access control, policy consistency, visibility, remote access support and operational manageability across the environment.
More consistent secure access across locations
Users across branches, offices and remote locations could be supported through a more standardised secure access model, reducing site-by-site exception handling.
Improved identity-aware access control
Access policies could be better aligned to user identity, role, application requirements and business context, rather than to network location alone.
Reduced reliance on legacy access patterns
The organisation moved toward a more flexible model for remote access, cloud access and internal application connectivity, reducing dependency on site-bound VPN patterns.
Stronger security policy consistency
Security controls could be applied more consistently across users, locations, cloud applications and traffic types, reducing policy drift across sites.
Better visibility and supportability
The operating model improved visibility into access behaviour, policy handling and troubleshooting pathways for support teams.
A more scalable network security model
The environment became better positioned to support distributed users, cloud applications and future operating changes without rebuilding the access architecture.
The value was not simply replacing legacy remote access or modernising connectivity. The value was creating a more consistent secure access model across the business.
