Unlocking the Full Potential of Unified SASE: An Interview with HPE’s Chris Hines


As organizations pivot toward more distributed and fragmented models of work, cybersecurity measures must adapt to keep pace with the evolving threat landscape and expanding attack surface.

In an in-depth interview with Chris Hines, VP of Strategy and Global Marketing at Axis Security, a recent acquisition by HPE, we explored the evolution of unified SASE as the next step in adaptive, integrated security solutions that address today’s complex challenges.

The Evolving Landscape of Remote and Hybrid Work

The COVID-19 pandemic, coupled with technological progress, has reshaped modern work environments. As organizations grapple with the change toward fragmented and dynamic work environments, the threat landscape and attack surface have expanded alongside, emphasizing the need for nimble and adaptive cybersecurity solutions that can address risks that originate both internally and externally: from malicious admins, end users, devices and threat actors aiming to exploit any weakness.

In this rapidly evolving landscape, traditional security architectures are no longer sufficient. Secure Access Service Edge (SASE) has emerged as a strategic imperative for businesses aiming to cope with new challenges and thrive in this new world. Notably, unified SASE offers an effective, streamlined approach to achieving robust security and efficient networking. This article explores the core aspects of unified SASE, why it’s essential for modern cybersecurity and how to get started on the SASE journey.

From Siloed Solutions to Unified Platforms

Historically, cybersecurity technologies such as Cloud Access Security Broker (CASB), Secure Web Gateway (SWG), and Zero Trust Network Access (ZTNA) were implemented to address distinct challenges. But as both IT environments and cybersecurity threats grow in complexity, there’s a clear shift towards integrated solutions.

Chris Hines underscores this transition, highlighting the complexity, cost and security challenges businesses face when managing multiple solutions, especially in a remote and hybrid work era. Moreover, vulnerabilities and user experience issues associated with traditional remote access technologies such as VPNs further exacerbate these challenges.

“There are three key factors driving the need for SASE adoption today: ineffective legacy security, unnecessarily complex networks, and obsolete solutions,” notes Chris Hines.

Enter Unified SASE

Introduced by Gartner in 2019, Secure Access Service Edge (SASE) emerged as a groundbreaking concept. It blends networking and security functionalities into a holistic policy-based platform, facilitating seamless collaboration between networking and security teams. Gartner predicts that “by 2025, 50% of new SD-WAN purchases will be part of a single-vendor SASE offering, up from 10% in 2022.”

Unified SASE converges the functions of network and security into a single, cloud-native platform, significantly reducing the complexities and inefficiencies associated with disjointed point solutions. It is based on two core technology sets:

  1. WAN Edge Services (SD-WAN): Software-Defined Wide Area Networking offers robust, flexible network connectivity. It automates the routing of network traffic to improve application performance and deliver a better user experience.
  2. Security Service Edge: Includes Zero Trust Network Access (ZTNA), Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Digital Experience Monitoring (DEM). This provides a comprehensive security layer by governing user access, filtering web content, managing cloud application use, and monitoring end-user experience.

Benefits of Unified SASE

By integrating WAN Edge Services and Security Service Edge into a single-vendor solution, unified SASE offers numerous advantages:

  • Enhanced Security Posture: Universal security policies paired with centralized access controls heighten threat detection and response capabilities.
  • Operational Efficiency: Merging networking and security functionalities minimizes complexities, promoting cross-functional collaboration.
  • Improved User and Admin Experience: With automatic routing of traffic and enforcement of Zero Trust policies, both user and administrator experiences are optimized without compromise to security.
  • Cost-Efficiency: A unified model inherently reduces capital and operational expenses, scaling seamlessly with evolving business requirements.

How to Begin Your Unified SASE Journey

Though implementing a unified SASE framework may seem daunting, with the right strategy and a reliable partner, you can make the transition to SASE smoothly and securely without disrupting existing operations.

Here are five key steps Chris Hines outlines that successful SASE implementations follow:

Step 1: Establish SASE Goals and Requirements

Determine your organization’s specific goals, needs, and criteria for a SASE framework. Evaluate your existing network and security infrastructure to identify any gaps, challenges, and available resources.

Step 2: Choose a Single-Vendor SASE Solution

Compare and assess different SASE vendors based on factors such as capabilities, coverage, performance metrics, scalability, reliability, customer support, and cost structure. Choose a well-architected, single-vendor SASE solution that is integrated, unified and easy to use.

Step 3: Formulate Your SASE Implementation Strategy

Collaborate with your chosen SASE provider to outline your network topology, security policies, user groups, app profiles, and connectivity options based on best practices. This step should be a joint effort with your SASE provider to ensure success.

Step 4: Initiate SASE Deployment in Phases

Start SASE implementation by deploying essential elements like agents, connectors, SD-WAN devices, or private PoPs via a central management dashboard. Migrate users, devices, physical locations, and applications to your new SASE architecture in a phased or batched manner. SASE’s flexibility allows it to work alongside existing solutions, offering you the pace of deployment that suits your team’s readiness.

Step 5: Unlock the Full Potential of SASE

As the deployment progresses, utilize the tools and dashboards provided by your SASE provider to gain operational insights and real-time visibility. This will allow you to fine-tune your SASE implementation and even discover new areas where SASE could add more value to your business.

By following these steps, you’ll be well on your way to leveraging the full potential of unified SASE, thereby strengthening your security posture and improving network performance.
