Banking Technology
Modern banks require sophisticated technology stacks including next-generation core banking systems, digital banking platforms for retail and corporate customers, open banking APIs mandated by OJK, and bank-grade cybersecurity frameworks. The transition from legacy mainframe systems to cloud-native, microservices-based architectures is one of the most complex digital transformation programs in any industry. Arunika Consulting helps banks implement digital banking technology covering core modernization, digital channels, API ecosystems, and security infrastructure compliant with POJK 12/2019.
Compliance Warning
This industry is considered high risk and may receive closer attention from tax authorities. Professional tax consultation is strongly recommended.
Technology Challenges
Core Banking Modernization
Migrating from legacy core banking systems (COBOL on AS400 or mainframe) to cloud-native platforms is high-risk, high-reward — involving millions of accounts and zero downtime tolerance.
Open Banking API Compliance
OJK mandates open banking requiring banks to expose standardized APIs with robust security. API gateway implementation must balance openness with data protection.
Bank-Grade Cybersecurity
Banks are primary targets for cyber attacks. Security systems must meet the highest tier of protection including SIEM, SOAR, DLP, and zero-trust architecture.
Digital Channel Experience
Customers expect seamless mobile and internet banking experiences comparable to fintech apps, requiring modern front-end architectures and real-time backend processing.
Regulatory Technology & Compliance
POJK 12/2019 and related regulations require comprehensive IT governance, business continuity management, data center resilience, and regular compliance reporting to OJK.

Frequently Asked Questions
What are the biggest challenges in core banking system migration?
Core banking migration is one of the highest-risk projects a bank can undertake. Key challenges include: data migration for millions of accounts and historical transactions, maintaining zero system downtime during cutover, ensuring continuity of OJK and BI regulatory reporting, training thousands of tellers and customer service officers on new systems, and parallel running of legacy and new systems during transition. Typical projects take 2-4 years with budgets of IDR 100 billion to 1 trillion.
What does POJK 12/2019 require for banking IT?
POJK 12/2019 on Banking IT Implementation requires banks to have: an IT master plan aligned with business strategy, IT risk management framework, primary and disaster recovery data centers with minimum 100km separation, information security management system, electronic data preservation for 10 years, business continuity plans tested semi-annually, and comprehensive IT compliance reports submitted to OJK.
How does open banking work in the Indonesian banking context?
Indonesia's open banking framework (SNAP - Standar Nasional Open API Pembayaran) mandates standardized APIs for payment initiation, account information, and other banking services. Banks must expose APIs with OAuth 2.0 security, standard data formats, and agreed service levels. The ecosystem enables fintech companies to build services on top of banking infrastructure while maintaining data security and customer consent requirements.
What cybersecurity threats do Indonesian banks face most?
Indonesian banks face increasing threats including: DDoS attacks targeting digital banking channels, ransomware targeting critical infrastructure, phishing campaigns targeting customers, insider threats from employees or vendors, and API-based attacks exploiting open banking interfaces. The Indonesia Financial Services Authority (OJK) requires banks to maintain Security Operations Centers (SOC) and participate in sector-wide threat intelligence sharing.
How are Indonesian banks adopting cloud technology?
Cloud adoption in Indonesian banking follows OJK's cloud computing regulation (POJK 11/2022) which permits public and hybrid cloud for non-core systems while requiring stricter governance for core systems. Banks typically start with cloud deployment for digital channels and analytics, then migrate core systems as cloud-native cores mature. Major Indonesian banks are adopting hybrid models with critical systems in private cloud and digital platforms on public cloud infrastructure.
What is the role of AI in modern banking technology?
AI applications in banking span: credit scoring and underwriting using alternative data, fraud detection through transaction pattern analysis, customer service via intelligent chatbots, personalized product recommendations based on spending patterns, anti-money laundering (AML) transaction monitoring with reduced false positives, and predictive analytics for customer churn prevention and cross-selling opportunities.
Will system migration disrupt daily operations?
We usually use a parallel-run approach so the old and new systems operate together during transition, reducing downtime and data risk.
Can accounting software connect to POS and bank data automatically?
Yes. We design API and import workflows for POS, marketplaces, and bank statements to reduce manual entry and reconciliation errors.
Which software is best for my industry?
The right choice depends on transaction volume and complexity. We assess your workflow before recommending cloud accounting, POS, ERP, or dashboard tools.
