Identify Security Gaps Across Before They Reach Production
Tristha helps financial enterprises assess security controls across applications, APIs, identities, sessions, data flows and connected systems before weaknesses affect customers, operations or institutional trust.
Expanding digital attack surfaces
can expose financial journeys across mobile applications, web platforms, APIs, cloud services, middleware and third-party integrations.
Authentication and access-control
gaps can allow inappropriate access, weak privilege separation, session misuse or incorrect approval behaviour across critical workflows.
API and integration
weaknesses can expose sensitive data, permit unauthorised requests or allow connected services to process incomplete, manipulated or repeated transactions.
Sensitive data exposure
can occur through insecure storage, logs, error messages, browser behaviour, application caches, notifications or poorly controlled data exchanges.
Input and configuration
weaknesses can create security risks when applications fail to validate requests, restrict unsafe values or apply approved configurations consistently.
Business-logic abuse
can remain undetected when testing focuses only on technical vulnerabilities without assessing transaction manipulation, limit bypass, duplicate processing or misuse of financial workflows.

Why Tristha
BFSI security context helps Tristha
assess security through the lens of financial transactions, customer identities, approval workflows, sensitive records and operational risk.
Techno-functional testing capability
connects technical security controls with business rules, transaction behaviour, user roles and downstream financial outcomes.
Remediation and retest discipline
supports clearer validation of approved fixes, recurring security checks and regression coverage after application or configuration changes.
Risk-based security scenarios
focus effort on critical journeys, sensitive data, high-impact actions, privileged access and workflows where control failure carries greater business impact.
Connected-workflow validation
extends testing across digital channels, APIs, middleware, backend platforms and third-party services instead of assessing every layer in isolation.
Structured QA governance
gives teams visibility into the affected workflow, identified gap, business impact, reproduction conditions, remediation status and residual testing observations.
A secure interface means little if the transaction path remains exposed.
Client Outcomes,
in Their Own Words
We sincerely appreciate the expertise and dedication demonstrated by Tristha & Finonyx in supporting our Performance Engineering and Test Automation efforts during the Flexcube 14.7 upgrade project. Their proactive approach, technical proficiency, and untiring commitment were instrumental in the success of this upgrade.
A key highlight was their exceptional performance engineering efforts, which covered all critical transactions across Flexcube Modules, OBBRN, APIs, ATMs, Mobile Applications and Other Application Interfaces. The team effectively simulated real-world production scenarios, generating various transaction loads within SLA-defined timeframes. This rigorous testing helped validate the application’s performance under actual operating conditions.
Additionally, TerrA’s capability to automate testing across various Flexcube 14.7 modules, including Web and APIs ensured comprehensive end-to-end test coverage for the base Flexcube modules. We also greatly appreciate the extensive training and dedicated support provided to the QA & Testing team and various Business Units/Teams on TerrA.
We are truly grateful for their contributions on this great Project Everest and looking forward to future collaborations.

We appreciate the support provided by Tristha & Ifinity in our Test Automation and Performance Engineering efforts during the Temenos T24 upgrade project. Their structured approach and technical expertise contributed to the overall execution of the upgrade. One key aspect was the ability of their automation platform ‘TerrA’ to support testing across multiple platforms, including web, mobile, APIs, databases, and file validations, enhancing test coverage. Additionally, their performance engineering efforts included testing critical transactions across T24, ATMs, and mobile applications. By simulating real-world transaction loads within SLA-defined parameters, they contributed to the validation of the application’s performance under operational conditions. We acknowledge their contributions to the project and appreciate the collaboration.

The successful completion of our Temenos T24 upgrade project required strong collaboration, effective solutions, and structured execution. Tristha & Ifinity played a role in supporting our efforts by contributing to test automation and performance validation, helping us improve overall efficiency and risk mitigation during the transition. By leveraging automation in testing processes, we were able to enhance quality assurance and optimize resources, ensuring a smooth and controlled go-live. Additionally, performance testing efforts contributed to validating system stability across key banking channels, aligning with our operational and customer service objectives. We acknowledge their contributions to the project and appreciate the collaboration in delivering this strategic initiative.

We had been constrained for months by our dependency on the switch and a rigid simulator that forced all test traffic through the switch layer. Working with Tristha’s SiPay simulator, we were able to bypass switch entirely and test directly against the core by building the required AS 2805 flows in SiPay, with no new code and no configuration changes to our environment, and this has now unlocked faster regression and far better reuse of our existing script automation assets.
