Airtel’s Sharat Sinha: Securing Digital Borders

In 2025, enterprises faced an increasingly borderless digital world – one where data, applications and threats move seamlessly across continents.

For Sharat Sinha, CEO of Airtel Business, this past year represented “more than just another year of digital progress”, but “a decisive leap as technology continued to accelerate the creation of a borderless digital ecosystem, where breakthrough innovations fostered transformative cross-border collaborations, driving new models of growth for enterprises worldwide.”

As online collaboration expanded and generative AI embedded itself in business workflows, the global economy became more reliant than ever on secure, intelligent infrastructure.

“Today, seamless and secure connectivity has become the foundation that is enabling organisations to scale, compete and lead on the global stage,” Sharat explains.

That foundation includes advanced fibre and subsea systems, cloud and edge technologies – each now a target and a tool in the cybersecurity landscape.

From network speed to infrastructure assurance

Security has evolved beyond firewalls and monitoring – it is now embedded within the digital fabric of connectivity. Sharat captures this strategic shift: “For enterprises, the question is no longer just ‘Is my network fast enough?’ but ‘Is my digital infrastructure resilient, secure and future-ready?’”

That redefinition demands integration.

“Fragmented networks and siloed cloud deployments are therefore giving way to integrated digital infrastructure, where high-capacity connectivity, high-performing cloud, cybersecurity and data centres are architected as one stack rather than being separate line items,” says Sharat.

Such integration allows enterprises to move towards a unified security posture – reducing lateral risk, improving visibility and strengthening compliance under diverse regulatory environments.

Looking ahead, Sharat sees a significant inflexion point: “As AI, edge and IoT converge with surging cloud adoption, intelligent and adaptive networks will become indispensable.

"Key trends like AI-powered networks and technology solutions, along with zero-trust security, will continue to redefine how global businesses future-proof their operations for agility, security and scale.”

Securing global infrastructure: The subsea frontier

As digital traffic surges worldwide, protecting the backbone of internet infrastructure becomes a fundamental cybersecurity challenge.

“Submarine cables with their next-generation fibre and network architecture will continue to serve as the backbone of global connectivity, carrying nearly all intercontinental data traffic,” Sharat notes.

To mitigate systemic risk, “the move toward diversified cable routes and advanced fibre investments is therefore vital for supporting high-performance data exchanges and future-proofing infrastructure against geopolitical and environmental risks.”

Airtel Business is taking a proactive role in securing these global links. “We have been championing this international data flow by making Asia, especially India, an anchor for international data flows, especially in routes between South-East Asia, Africa and Europe,” Sharat explains.

“We have brought global cable systems like SEA-ME-WE-6 and 2Africa Pearls home to Indian shores this year,” he adds.

For cybersecurity professionals, this diversification is as much about resilience as capacity – reducing single points of failure and reinforcing the trustworthiness of global data transport systems.

Trust, sovereignty and sustainable security

Beyond infrastructure performance, digital trust now rests on sovereignty and sustainability. Sharat points out that “sustainable data centres and AI-ready cloud platforms that offer flexible, secure and sovereign service are also emerging as standards for enterprise growth.”

This focus on sovereignty coincides with stricter global data governance frameworks.

“Leading investments in purpose-built data centre facilities that are sustainable and renewable energy-powered are therefore taking predominance as the new benchmark for ensuring data centre energy efficiency and environmental responsibility,” Sharat adds.

In cybersecurity terms, sustainability means more than green credentials – it signifies resilience, continuity and long-term assurance for mission-critical services.

Airtel’s approach blends security with sustainability, integrating renewable-powered facilities into its cloud and network ecosystem to meet both regulatory and environmental expectations.

Outlook 2026: Zero‑trust at global scale

The year ahead will see enterprises strengthen their zero‑trust models and embed automation into their cyber‑resilience frameworks. As threats grow in sophistication, connectivity providers will play an even broader defensive role.

“As enterprises worldwide look to 2026 and beyond, they will need partners who will harness intelligent, secure and sustainable digital infrastructure to power their always-on collaboration and innovation,” says Sharat.

“At Airtel Business, our ambition is to lead this new era of global connectivity by combining our diversified subsea and terrestrial networks with AI-ready cloud, sustainable data centres and high-security,” he affirms.

This interlinked framework of network intelligence, cloud sovereignty and continuous protection will underpin the next generation of cyber resilience.

As Sharat concludes, “An integrated digital foundation will be the much-needed backbone for a new era of borderless collaboration, enabling enterprises to innovate with confidence in a world where connectivity has become the foundation of competitiveness.”
