Digital resilience has shifted from a technical safeguard to a strategic imperative as enterprises confront rising cyber threats, power instability and increasingly complex hybrid environments. Organisations that fail to embed resilience into their infrastructure risk not only operational disruption, but lasting damage to revenue, reputation and customer trust.
Enterprises building resilient digital infrastructure face a strategic technology decision that extends well beyond budget considerations: build a foundation that lasts, or risk a collapse far costlier than money alone.
“The failure to invest in resilient digital infrastructure will not only impact business continuity and result in substantial revenue loss when things go wrong, but the ripple effects include irreparable brand and reputational damage that can be debilitating for any organisation,” says Ntando Dhlamini, head of networking solutions at Makwa IT.
The cost of doing nothing
Many organisations remain hesitant to commit capital expenditure to fortify their digital architecture against power disruptions, cyberattacks and other threats that could compromise system availability, disrupt operations, expose sensitive information or open the door to ransomware and phishing campaigns.
In today’s hyper-connected economy, a single point of failure can trigger a domino effect across partner interfaces and customer touchpoints.
“It should not be an either-or case of cost optimisation or building resilient systems. In an environment where security threats are becoming more sophisticated and damaging, building system resilience should be an intuitive thing,” Ntando says.
Lesedi Modibane, head of digital platforms and solutions at MakwaIT, frames the issue differently: “What is the opportunity cost of not having this? Does cost supersede the importance of business continuity? The question should rather be: what value do we get out of implementing resilience?”
MakwaIT’s management frameworks provide building blocks for transitioning a legacy to a resilient digital ecosystem spanning advisory, design to operational management and support. Choice of business aligned Capital expenditures (Capex)-heavy resilience investments or scalable Operating Expenses (Opex) models with cloud-first architecture, continuous monitoring, and automated updates.
Ongoing performance fine-tuning, 360 visibility, and SLA-backed support are typical of managed services.
Vulnerable entry points
Security breaches remain one of the biggest vulnerabilities in hybrid and multicloud environments, driven largely by inconsistent policy and governance across different network and cloud environments. Remote work compounds this risk by placing employees outside the protected perimeter of corporate networks.
“This misalignment is a vulnerable entry point that makes it much easier for anyone to exploit,” Ntando says.
“The second challenge is misconfiguration of access control. When you move from a main network to a hybrid and cloud infrastructure, you introduce additional risk and vulnerability into your architecture. Policies and governance need to be consistent and uniformly applied across all environments to mitigate potential vulnerabilities.”
The legacy systems problem
Managed services can help overcome the challenges of legacy complexity by introducing cloud-based management layers that improve visibility and control, without the need for full rip-and-replace modernisation.
In this context, both Ntando and Lesedi identify legacy systems as a significant bottleneck. “There are a lot of legacy systems within our digital ecosystems, resulting in limited telemetry, even if you have the toolsets to better visualise your environment for digital resilience,” Ntando notes.
Lesedi adds that this includes legacy applications that cannot fully adapt to cloud-native architectures, or that block cloud migration paths due to obsolete operating systems or older programming languages. He also flags a common misconception: that having a backup system is equivalent to having a resilient one.
“We have a solution that addresses application modernisation and enables us to bubble-wrap an application sitting on an old operating system or older programming language such as COBOL or Pascal,” Lesedi explains. “Through our solutions, we are able to decouple the database and the application, bubble-wrap the application itself, and make it ready for cloud migration or deployment on a virtual machine. It becomes interoperable and can be seamlessly integrated with other applications.”
From an observability perspective, MakwaIT has the capability to wrap around legacy equipment, enabling end users to use fewer but more predictive monitoring tools, thereby covering the full digital ecosystem, including legacy infrastructure.
Additionally, managed services can curate a roadmap from legacy complexity to hybrid and finally cloud-based management layers, enabling visibility and control without full rip-and-replace modernisation.
Aligning IT and business strategy
A harmonised IT and business strategy is the foundation for building resilient systems and networks, according to Lesedi. Organisations need to build their systems with intent and, where possible, encode resilience into infrastructure from the outset.
“You need to identify the issues today and then embed things like digital twins. I would advise organisations to position a cloud strategy at the heart of their business. You may have in-house IT support, but human error creeps in, and when things go wrong at awkward hours, support staff might not be available. When you are hosting with a cloud platform, you have 24-hour surveillance and monitoring,” he says.
IT service management aligns technology with business outcomes through predictable costs, scalability and simplified network operations (single-pane-of-glass management, automation and zero-touch provisioning).
The digital resilience maturity model
Lesedi defines resilience in practical terms: “Resilience, to us at MakwaIT, is how an enterprise is protected against digital disruptions that impede business continuity. These include cyberattacks, operational disruptions that may impact infrastructure uptime, data security and protection, and the ability to effectively respond to digital threats.”
MakwaIT’s Digital Resilience Maturity Model maps organisations across five levels: Fragile, characterised by legacy systems and manual backups; Protected, with cloud adoption and POPIA-type controls; Responsive, with SOC capability and automated monitoring; Predictive, with AI-driven insights and integrated dashboards; and Adaptive Enterprise, where self-healing systems and continuous innovation are embedded in strategy.
External factors such as loadshedding and network outages also negatively affect resilience, Lesedi notes.
Beyond preparedness
Ntando argues that resilience has moved beyond a state of preparedness.
“A few years ago, we defined resilience as the ability to prepare for events such as disaster recovery. With the tools currently available, we do more than plan for what would happen if things go wrong. We proactively plan around being able to observe and measure how customer services might be impacted.”
“From a security perspective, we are continuously monitoring threats and automating how available playbooks adjust to those threats. From a digital perspective, we are not only ensuring that infrastructure is working, but seeking to minimise potential business disruptions regardless of what infrastructure it is hosted on. Resilience is no longer confined to ensuring infrastructure availability; it is about ensuring optimal performance and, by leveraging AI, anticipating and mitigating service disruptions,” she says.
What CIOs need to do now
As digital environments grow more complex, driven by IoT expansion, hybrid work models and multicloud adoption, Cisco Meraki managed services provide CIOs with a streamlined way to manage and scale operations without the need to expand internal teams.
These services can help overcome the challenges of legacy complexity by introducing cloud-based management layers that improve visibility and control.
Looking ahead, Ntando cautions that CIOs need to be conscious of the rapidly evolving technological landscape. Emerging technologies such as automation, AI, machine learning and chatbots have the potential to strain systems, particularly legacy systems not designed for these applications.
Lesedi agrees, adding that the business model should determine the type of network architecture required. “It is not helpful to add digital applications that come with their own issues when your model is not geared towards buffering against them. When you go digital and introduce payment capabilities into your system, customer and payment data is exposed to risk. You need to have the capabilities to do audit trails and see the traffic coming in. It is imperative that you ensure data, infrastructure and application security,” he says.
True resilience, the pair conclude, emerges when architecture, networking, security, observability, collaboration, platform and strategy are interwoven to create a foundation for sustainable growth.
