In the ever-evolving landscape of IT and cybersecurity, Secure Access Service Edge (SASE) has emerged as a transformative paradigm. By converging networking and security, SASE offers a holistic solution to the challenges of modern connectivity.

However, the journey towards successful SASE integration requires more than enthusiasm; it demands careful planning, meticulous assessment, and strategic execution.

Although it might sound simple, the deployment and management of a SASE architecture can be complex. For many, this complexity spikes when you start to consider the integration challenge.

In this blog post, I want to walk through a few essential steps to consider before embarking on SASE integration and, if you’ll allow me, I want to highlight how independent consulting and assessment services can prove a powerful resource.

Laying the Foundation: Preparing for SASE Integration

As you prepare to integrate a SASE architecture with existing networks and tools, a systematic approach is paramount.

There are 5 key areas that require specific attention in your integration planning.

Network infrastructure

Of course, you can deploy SASE over existing network infrastructure. However, you may need to consider what changes need to be made. This could involve deploying new edge devices or updating routing configuration.

Security infrastructure

There is no doubt the opportunity to consolidate existing security infrastructure, such as firewalls, intrusion detection systems, and web filtering systems is a key benefit. However, you may need to make some changes to how these systems are configured and managed.

Identity and access management (IAM) systems

A SASE architecture will need to integrate with your IAM system to provide secure access to applications and resources. You will need to configure your system accordingly.

Cloud applications

Providing secure access to your cloud applications, such as SaaS, PaaS, and IaaS is probably one of your main drivers. However, you are likely to have some work to do here to configure your cloud applications to work with your chosen architecture.

Third-party systems

Your new SASE solution may integrate with other third-party systems, such as SIEM tools and threat intelligence feeds; vendors such as Cisco will have integrations with Microsoft Sentinel and other SIEM platforms. This does mean you will need to undertake some configuration of these systems to work with your SASE solution.

It can be quite a challenge if your resources are already stretched and overworked.

That said, it’s important to carefully plan and test your SASE integration before deploying it in production.

Working with an experienced MSP will get you access to support and guidance on the integration process for your organisation.

To get you started then, here are 4 key considerations that can help you pave the way for a seamless and successful integration process.

1 - Initiate an Infrastructure Assessment

Before embarking on any integration journey, it’s crucial to understand your existing infrastructure. A thorough assessment helps identify strengths, weaknesses, and areas that need improvement. By evaluating your network architecture, security protocols, and user requirements, you’ll gain insights into the gaps that SASE integration can fill. Maintel offers a range of assessment and audit services that can support you in this task. To find out more about how you can go about assessing your infrastructure, get in touch and one of our team will walk you through the options.

2 - Start with integration objectives

What are your goals for SASE integration? Are you looking to enhance security, optimise network performance, or achieve a balance between both? Defining clear integration objectives helps align your efforts with tangible outcomes. Whether it’s streamlining remote access, improving connectivity to your cloud infrastructure/applications, or fortifying data protection, having a well-defined roadmap is essential.

3 - Construct a Migration Plan

A migration plan outlines the systematic steps for transitioning from your current setup to the SASE framework. It includes considerations for data migration, application compatibility, security policies, and user training. A carefully crafted migration plan minimises disruptions and ensures a smooth transition for your workforce. And, depending on the size of your estate, the best plans are created with the guidance of third-party experts.

4 - Create a timeline that is realistic

Integration doesn’t happen overnight. Establishing a realistic timeline is crucial for managing expectations and resources. Factor in assessment time, planning, testing, deployment, and post-deployment optimisations. A well-structured timeline ensures that every phase of the integration process receives the attention it deserves.

Sounds straightforward, right? Of course, implementing a new architecture has its challenges and a bunch of hidden pitfalls. And if your team is stretched already, the temptation is to cut a few corners here and there.

How can you avoid that? Let’s look at what Maintel could do as a starter.
