How did HT Solutions help Hashbank strengthen Kubernetes security together with Tigera?

After rapid growth and attracting tens of thousands of users, Hashbank needed a secure and scalable infrastructure capable of supporting fast development and increasing workloads.

After transitioning from a monolithic architecture to Kubernetes-based microservices, the bank gained greater flexibility but also faced new challenges in managing communication and security across hundreds of microservices. In a fintech environment, Hashbank needed full network visibility and a strict Zero-Trust architecture without disrupting development or the operation of critical services.

HT Solutions, in collaboration with Tigera, implemented Calico Enterprise in Hashbank’s Kubernetes production environment, delivering a secure and manageable Kubernetes infrastructure. The solution enabled a Zero-Trust approach based on the “default-deny” principle. As a result, communication between workloads became possible only through explicitly authorized access.

With detailed network policies, hashbank can manage communication at the workload, application, and Namespace levels. Microsegmentation separated different parts of the platform and reduced the risk of unauthorized lateral movement.

Calico Enterprise also provided technical teams with real-time network visibility. They can identify:

• The source and destination of connections;

• The port being used;

• Whether traffic is allowed or blocked;

• The security policy that made the decision.

Through staged policy implementation, teams can assess the impact of new rules before enforcing them, reducing the risk of disrupting legitimate services.

As a result of the project, Hashbank gained full visibility and improved control over its Kubernetes network. Workload and Namespace isolation were strengthened, auditing was simplified, and issue detection became faster.

By combining HT Solutions’ expertise with Tigera’s technology, a secure and scalable Kubernetes environment was created, ready to support hashbank’s continued growth.
