Embracing SASE: Navigating the path to unified network and security

As organisations worldwide navigate the complex digital landscape, the demand for a more integrated and comprehensive approach to networking and security has never been greater. Enter SASE (Secure Access Service Edge) technology—a transformative framework that promises to converge networking and security functions into a unified cloud-delivered architecture. In this article, we explore the evolution of SASE, its key drivers, and the critical role of managed service providers (MSPs) like Tata Communications in enabling seamless SASE adoption.

Traditionally, the SASE market has been defined as the convergence of Secure Service Edge (SSE) and Software-Defined Wide Area Network (SD-WAN) capabilities. However, as organisations increasingly adopt multi-cloud strategies and distributed workforces, the limitations of this definition have become apparent. Working with multiple vendors to address specific networking and security needs often leads to performance and security tradeoffs, underscoring the need for a more holistic approach to SASE adoption.

The shift from perimeter-based security to a more dynamic, cloud-centric approach has catalysed the evolution of SASE. With applications migrating to the cloud and remote work becoming the norm, traditional security models are no longer sufficient.

SASE addresses these challenges by consolidating networking and security functions into a single, cloud-delivered architecture. By adopting SASE, organisations can streamline complexity, enhance agility, and ensure consistent security across distributed environments.

What’s driving the adoption of SASE?

The need for uniform policies, regulatory compliance, and governance across network and security is paramount as applications move to the cloud. Additionally, the rise of hybrid work models and increased cloud adoption has highlighted the importance of supporting and securing cloud applications and remote workers.

SASE offers a solution by integrating SD-WAN with core security components such as Secure Web Gateways (SWG), Cloud Access Security Brokers (CASB), Zero Trust Network Access (ZTNA), and Firewall as a Service (FWaaS) into a unified cloud-delivered architecture.

The emergence of single-vendor SASE signifies a critical trend towards converging disparate security and networking technologies. However, achieving "any-to-any connectivity" within the enterprise necessitates true network modernisation for SASE to benefit all teams effectively.

The role of Managed Service Providers (MSPs)

SASE adoption may be on the rise but deploying it is a whole different ball game. Implementing SASE across an organisation can be challenging, especially when navigating integration complexities and evolving technology landscapes. This is where MSPs like Tata Communications play a crucial role.

By partnering with an MSP, enterprises can leverage expertise, streamline deployment, and ensure continuous support for their SASE initiatives. In fact, according to a recent study commissioned by Tata Communications, approximately 50% of enterprises rely on service provider partners for managing their SASE initiatives, underscoring the importance of strategic partnerships in SASE adoption.
