Global Capability Centers (GCCs) are no longer back-office processing centers; they are strategic innovation engines that deal with mission-critical product development, data science, and platform engineering. There are over 1,900 GCCs in India, which have earned approximately 65 billion and have an employment of about 1.9 million professionals, which is a large scale that makes the issue of GCC security an economic and operational issue of concern. 

Traditional network boundaries have been erased by the GCC work scale and sensitivity, alongside migration to the cloud, hybrid work, and API-driven operations. At the same time, threat actors have now become more tactical: ransomware, data exfiltration, and compromise of supply chains now target distributed teams and third-party services as opposed to just one data center. These two forces have generated a need for a new security posture: Zero-Trust Architecture (ZTA). 

A Brief History

The first GCC security measures, such as perimeter firewalls, VPNs, and trusted internal networks, mirrored enterprise IT at the time. That model was enough in cases where the majority of workloads were on-premise and access was office-bound. When GCCs were turned into cloud-native hubs (microservices, DevOps pipelines, and external data feeds), the trusted inside/untrusted outside assumption started to collapse, lead times of breach detection became longer, and horizontal movement and insider risk increased. As a result, perimeter defense was no longer adequate and was now required.

Why Zero Trust Is The Next Best Thing

Zero Trust does not count on presumed trust but refers to the verification of trust: never trust, always verify. The new GCC’s business realities are global workforces, temporary computing, and more precise data access requirements that are directly related to its core tenets of identity as the new perimeter, least privilege, micro-segmentation, and continuous monitoring. The market momentum indicates the same trend: According to industry surveys and analysts, Zero Trust is shifting faster and faster, and most organisations actively pursue or consider Zero Trust programs in 2024-2025.

Transformations in the GCCs

The following is a succinct perspective of the transformation underway of GCC security controls towards the Zero-Trust practices.

Security Area Old Way (Perimeter Defence) New Way (Zero-Trust Approach)
Access Control Any person within the office system was automatically trusted. No access can be granted without verifying every user and device.
User Permissions Wide access is provided to teams or positions. The access given is restricted in time and purpose.
Network Security Lined by firewalls and solid boundaries. Separated into smaller areas in order to prevent the spread of one violation.
Monitoring Audited occasionally. Monitored with real-time warning and data analysis.
Data Protection Data encryption was done on storage alone. Data protection is provided during storage, sharing and use
Governance Departments handled policies independently. Core policies are used in all the GCC destinations.

Economic Advantages

It is not a security game to go zero trust; rather, it is an economic enabler for the GCC and parent organizations. 

  • Zero Trust will reduce the extent of breaches, hence financial losses due to ransomware and data theft.
  • Regulatory alignment with regular identity-based controls, cross-border compliance, and audits are more straightforward. 
  • Agility in operations and secure-by-design access patterns help in the acceleration of safe developer productivity and speedy deployment of world services. 
  • Mature zero-trust postures demonstrated by GCCs instill greater confidence in internal businesses and external customers, enhancing contract bids and premium positioning.

Recent studies and market forecasts indicate that there is strong business momentum currently supporting these architectures as vendors and businesses increase their investments in Zero-Trust toolkits. 

Organisational And Human Changes

It is not just a technology that will provide resilient GCC security. Leaders should invest in three related areas, namely: 

(1) Talent – Establish cybersecurity Centres of Excellence within GCCs and train engineers in secure coding and cloud hardening; 

(2) Process – Introduce security gates into CI/CD and procurement; and 

(3) Culture—Make verifying continuously the responsibility of product, data, and business teams. GCCs that position Zero Trust as a program (people + process + tech) instead of a product have a higher payback faster and more sustainably. 

Future Perspective

The three years to come will witness Banking GCCs as key constructionists of two long-term trends:

  • BaaS is offered by modular API stacks that allow non-bank platforms to integrate financial products on a large scale.
  • AI-native financial services – The operationalised model of personalised credit, pricing and risk will be implemented as a continuous production process by GCCs.
  • GCC’s Interoperable Ecosystems – GCCs will knit regulatory sandboxes, identity networks and payment rails into cross-border Open Finance flows.

Open Finance is not a product but rather an operating model; the operating muscle is provided by GCCs. With GCCs taking on more engineering, risk, and product responsibilities, banks can become more competitive with fintech-native platforms without losing the trust of customers and regulators.

New Trends And Short-Term Prospects

There are several trends that are expected to increase into 2026, including extensive migration of the existing VPNs to identity-based access, ubiquitous JIT provisioning, and more use of AI to detect and respond to threats. GCCs should be vigilant because attackers will continue to target weak points, such as unmanageable endpoints at Tier-2/3 locations, poorly managed cloud identities, and third-party vendors.

The urgency is highlighted by recent national and industry reports: the landscape of cyber threats in India was registered in significant amounts of malware and targeted ransomware incidences in cities and industries, which supports the necessity of contemporary architectures and prompt detection. 

Conclusion

The direction of GCC security is evident: perimeter defense brings stability; Zero Trust provides resilience and a competitive edge. This will become a necessity rather than a pleasant surprise in case GCCs continue to perform their strategic duty, which is to provide innovation at scale, safeguard customer trust, and conduct global operations. Chief executive officers who focus on identity, visibility, and least privilege today will open the door to reduced risk, regulatory certainty, and increased rates of economic payoff throughout their GCC presence.
