SASE convergence: Your strategic guide to evolving network security
Cybersecurity · Feb 10, 2026
As organizations mature, they are recognizing that network and cybersecurity can no longer operate in silos—these elements must work hand in hand to deliver seamless, secure connectivity. The limitations of legacy network security, which treated networking and security as separate disciplines, are becoming harder to ignore in this evolved landscape. This is especially true as hybrid work models and cloud transformation dissolve the traditional perimeter, leaving legacy models struggling to secure remote users and SaaS applications while maintaining high-performance connectivity.
TELUS Business recently partnered with IDC Canada to explore this evolution. The resulting report –
The State of SASE: A strategic guide for IT and Security leaders
– sheds light on how IT leaders are moving beyond basic connectivity to build a unified, intelligent, and secure edge via a Secure Access Service Edge (SASE) approach. SASE integrates software-defined wide area network (SD-WAN) and security service edge (SSE), offering a holistic approach to secure connectivity. By combining networking and security, SASE helps to simplify IT management and enhance protection. Let’s take a look at a few of the key drivers outlined below pushing organizations toward SASE.Security and networking convergence
Organizations break silos between Network Operations Center (NOC) and Security Operations Center (SOC) teams, unifying policy enforcement and visibility with an orchestration layer or a multivendor SASE solution.
Single-vendor SASE
Businesses consolidate SD-WAN and SSE under one provider for simplified management and policy consistency.
Cost and situational drivers
Factors such as mergers and acquisitions, compliance mandates, or vendor incentives drive SASE adoption.
Cloud security first
Enterprises prioritize Cloud Access Security Broker (CASB) and Secure Web Gateway (SWG) to secure SaaS applications, cloud workloads, and internet traffic.
VPN to ZTNA
Companies replace VPNs with Zero Trust Network Access (ZTNA) for secure remote access and least-privilege connectivity.

The hidden risks of DIY deployment
Some organizations may be tempted to try a do-it-yourself (DIY) build of a custom SASE architecture, however, organizations may underestimate the complexity, resource demands, and security risks of deploying and managing SASE in-house. It’s important to keep in mind that SASE is a long-term strategy, not just a type of architecture. Successful adoption requires a phased approach that aligns with existing infrastructure, security priorities, and operational needs. Additionally, organizations need to contend with:
- Implementation and configuration of SASE components
- Ongoing enforcement of network and security policies across users, devices, and locations, establishing a zero trust architecture
- 24/7 network and threat monitoring
- Incident response and recovery
This is where a managed security service provider like TELUS Business can be a strategic advantage. By partnering with experts who handle end-to-end implementation and ongoing management, organizations can scale down the complexity and reduce the strain on their internal network and security teams.
