Zero Trust Architecture for India — Never Trust, Always Verify
Perimeter-based security fails in cloud-first environments where users, devices, and workloads operate from everywhere. Opsio implements Zero Trust architecture — verifying every access request, enforcing least privilege, and assuming breach — across your AWS Mumbai, Azure Central India, GCP Delhi, and hybrid infrastructure, aligned to DPDPA and RBI cybersecurity requirements.

What is Zero Trust Architecture for India?
Zero Trust Architecture (ZTA) is a cybersecurity framework built on the principle of never trust, always verify, treating every user, device, and application as untrusted by default — whether originating inside or outside the corporate perimeter — and requiring continuous authentication and authorisation before granting access to any resource. Core scope areas include identity and access management through MFA and IAM systems such as AWS IAM Identity Centre and Azure Active Directory; micro-segmentation of networks into isolated zones to contain lateral movement after a breach; least-privilege access enforcement ensuring users and devices receive only the minimum permissions necessary for their tasks; continuous monitoring and analytics for real-time anomaly detection using tools like AWS GuardDuty, Microsoft Defender for Cloud, and Google Chronicle; data security through end-to-end encryption for data at rest and in transit; and device health verification integrated with endpoint detection platforms. Governing standards include NIST SP 800-207, which defines the formal ZTA reference architecture, alongside ZTNA and SASE frameworks for secure remote access, and India-specific mandates under DPDPA and RBI cybersecurity guidelines. Leading vendors active in this space include Palo Alto Networks, Microsoft, Cisco, and Google, each offering ZTA-aligned platforms spanning network, identity, and workload security. Pricing for enterprise ZTA implementations varies widely based on user count, cloud footprint, and tooling stack, with mid-market engagements in India typically ranging from INR 15 lakh to INR 80 lakh depending on scope. Opsio implements Zero Trust architecture across AWS Mumbai, Azure Central India, and GCP Delhi as an AWS Advanced Tier Services Partner, Microsoft Partner, and Google Cloud Partner, with ISO 27001-certified delivery from its Bangalore centre, 24/7 NOC coverage, a 99.9% uptime SLA, and explicit alignment to DPDPA and RBI cybersecurity requirements for Indian enterprises.
Zero Trust Architecture for Indian Enterprises
Traditional perimeter security assumes everything inside the network is trusted. This model fails catastrophically in Indian enterprise environments where employees work remotely across cities, applications span AWS Mumbai, Azure Central India, and GCP Delhi, APIs connect to global services, and compromised credentials bypass firewalls entirely. Zero Trust architecture operates on three principles: never trust, always verify; assume breach; and enforce least privilege. Every access request — whether from a user in Mumbai, a service in Hyderabad, or an API from a partner — is authenticated, authorised, and continuously validated regardless of network location. This approach aligns directly with DPDPA's data protection requirements and RBI's cybersecurity guidelines for regulated entities.
Opsio implements Zero Trust across the full stack: identity (IAM, SSO, MFA, conditional access), network (micro-segmentation, service mesh, private endpoints), data (encryption, DLP, classification aligned to DPDPA), and workload (runtime protection, image scanning, admission control). We align implementations with NIST 800-207 and integrate with your existing identity providers and security tools deployed in Indian cloud regions.

Service Deliverables
Identity-Centric Security
Implement strong identity verification with Azure AD, AWS IAM Identity Centre, Okta, or Google Workspace. Configure conditional access policies, MFA enforcement, and risk-based authentication for every user and service account — meeting RBI and SEBI identity management requirements.
Micro-Segmentation
Eliminate lateral movement with network micro-segmentation using cloud-native security groups in Indian regions, service mesh (Istio, Linkerd), and software-defined perimeters. Each workload communicates only with explicitly authorised peers.
Least Privilege Access
Implement just-in-time access, role-based access control (RBAC), attribute-based access control (ABAC), and privilege escalation workflows aligned to RBI IT governance requirements. Continuously audit permissions and remove excessive access.
Continuous Verification
Real-time posture assessment for every access request. Device compliance checks, user behaviour analytics, and session monitoring ensure trust is never static — it is continuously earned. IST-aligned monitoring from Bangalore.
Data Protection
Classification, encryption at rest and in transit, data loss prevention (DLP), and access logging for sensitive data — aligned to DPDPA data localisation and protection requirements. Ensure data is protected regardless of where it resides in Indian cloud regions.
Workload Security
Container image scanning, admission controllers, runtime protection, and supply chain security. Verify workload integrity from build to production across AWS Mumbai, Azure Central India, and GCP Delhi.
