An interaction with Mr. Sharat Sinha, CEO, Airtel Business
Cybersecurity is no longer just an enterprise concern. What are the biggest security risks India’s SMBs face today, and why is Zero Trust becoming essential rather than optional?
SMBs today face a perfect storm: rising ransomware and phishing attacks, limited IT expertise, supply chain vulnerabilities, and risks from outdated technology or untrained staff. These challenges can disrupt business continuity and damage reputation.
Zero Trust Security is now a necessity for Indian SMBs. With digital adoption accelerating and cyber threats growing more sophisticated, traditional perimeter defenses are no longer enough. Zero Trust ensures that every user, device, and connection is continuously verified, dramatically reducing the risk of unauthorized access and data breaches.
For Indian SMBs who often have limited IT resources but handle sensitive customer data, Zero Trust is a strategic imperative. It helps build resilience, safeguard customer trust, and enables secure, confident growth in a rapidly evolving digital landscape. Airtel’s approach makes Zero Trust accessible and affordable, so even small businesses can defend against advanced threats and regulatory risks.
Airtel has launched a fully managed Zero Trust Architecture solution for SMBs. What are its key differentiators, and how does it simplify cybersecurity for businesses with limited IT resources?
We designed our ZTA solution to be fully managed and easy to deploy—ideal for SMBs without dedicated IT staff. From initial setup to ongoing support, Airtel’s experts handle everything: seamless onboarding, centralized policy management, and continuous threat protection.
Our solution integrates with Airtel’s pan-India Internet Leased Line connectivity and leverages cloud-based security, so there’s no need for complex hardware or large capital investments. SMBs can choose standalone or bundled offerings, and our team ensures a smooth, disruption-free transition. This allows businesses to focus on what they do best, while we take care of their security.
Many SMBs hesitate to invest in cybersecurity due to cost and complexity. How does Airtel make enterprise-grade Zero Trust security both affordable and practical for this segment?
We know cost is a top priority for SMBs. That’s why our ZTA solution is designed to deliver enterprise-grade security at a predictable, scalable price—without the complexity or expense of traditional models. By leveraging cloud-native technology and managed services, we eliminate costly hardware and reduce the need for in-house IT teams.
Our customers get comprehensive threat protection, SSL inspection, data loss prevention, and 24/7 monitoring—all included in a single, affordable subscription. This means SMBs can invest in growth while staying safe, compliant, and resilient against evolving threats.
Looking ahead, how do you see the cybersecurity landscape evolving for India’s SMBs, and what role will managed security services play in strengthening their cyber resilience?
The threat landscape is evolving rapidly: attackers are using AI for personalized phishing, ransomware is targeting supply chains, and SMBs are increasingly in the crosshairs due to perceived weaker defenses. Today, even a small business can be a gateway to larger enterprise breaches.
SMBs should prepare for automated, relentless threats by adopting cloud-based, scalable security models like Zero Trust. Real-time monitoring, continuous authentication, and centralized policy enforcement are now essential. Embracing managed security services bridges the skills gap and ensures resilience. Partnering with trusted providers like Airtel helps SMBs stay ahead of threats and regulatory demands—without the burden of building in-house expertise.
Our vision is to make advanced, AI-powered, and fully managed security accessible to every SMB, so security becomes a foundation for growth—not a barrier. By combining our trusted connectivity, world-class partnerships, and innovation, we empower SMBs to grow confidently in a secure digital India. We’re here to ensure that every business, regardless of size, can compete and thrive in the digital age—safely and securely.

Zero Trust Architecture: A Smarter Approach to Cybersecurity
As businesses increasingly adopt cloud services, support remote work and connect more devices to their networks, traditional security models are proving inadequate. The old assumption that everything inside an organization’s network can be trusted no longer holds true. This is where Zero Trust Architecture (ZTA) comes in.
Never Trust, Always Verify
Zero Trust is a cybersecurity framework built on a simple but powerful principle: “Never trust, always verify.” Instead of automatically trusting users or devices because they are inside the corporate network, Zero Trust requires every access request to be authenticated, authorized and continuously validated, regardless of where it originates.
The Three Core Principles
Zero Trust is based on three fundamental ideas:
- Verify explicitly: Every user, device and application must be authenticated using multiple factors such as identity, device health, location and risk level.
- Least-privilege access: Users are granted only the minimum level of access needed to perform their tasks, reducing the potential damage if an account is compromised.
- Assume breach: Organizations operate on the assumption that attackers may already be inside the network. Security controls are therefore designed to detect threats quickly and prevent them from spreading.
Why It Matters for SMBs
Small and medium businesses are increasingly targeted by cybercriminals because they often lack the extensive security resources of larger enterprises. Zero Trust helps level the playing field by reducing the risk of unauthorized access, ransomware attacks and data breaches. It also provides stronger protection for employees working remotely or accessing cloud-based applications.
Contrary to popular belief, Zero Trust is not a single product that can be purchased. It is a security strategy that combines technologies such as multi-factor authentication (MFA), identity and access management (IAM), endpoint protection, network segmentation and continuous monitoring.
A Continuous Security Model
Unlike traditional security models that focus on protecting the network perimeter, Zero Trust places identity, devices and data at the centre of security. Every access request is evaluated in real time, and permissions can be adjusted or revoked if the risk changes.
As cyber threats become more sophisticated, Zero Trust has evolved from a best practice into a strategic necessity. For businesses of all sizes—especially SMBs—it offers a practical framework for strengthening cyber resilience and protecting critical digital assets in an increasingly connected world.
