RAG & Knowledge-Base Build Training for LLM Applications for the Banking & Financial Services Sector

Banks need answers accountable to auditors: credit analysts and compliance officers search clause-by-clause through policies, relevant POJK regulations, and decade-old committee memos. RAG saves significant search time, but every answer must show its source and never mix customer data into public-model prompts. The vector index becomes a new shadow database that must obey bank data-classification policy.

Why RAG & Knowledge-Base Build Training for LLM Applications is different in Banking & Financial Services

Banks need answers accountable to auditors: credit analysts and compliance officers search clause-by-clause through policies, relevant POJK regulations, and decade-old committee memos. RAG saves significant search time, but every answer must show its source and never mix customer data into public-model prompts. The vector index becomes a new shadow database that must obey bank data-classification policy.

Sector KPIs
  • Faithfulness score on bank-policy golden eval set
    Consistently above the quality baseline set by IT risk
  • Per-chunk classification coverage
    Nearly all chunks tagged with classification before user access
  • Citation-missing incidents
    Approaching zero after pipeline hardening
Relevant regulations & standards
  • POJK 11/POJK.03/2022 IT Risk Management for Commercial Banks
  • SEOJK 29/SEOJK.03/2022 Bank Cyber Resilience & Security
  • UU PDP No. 27/2022 β€” customer data as personal data
  • OWASP Top 10 for LLM Applications 2025 β€” LLM06 sensitive information disclosure, LLM08 vector & embedding weaknesses
Target roles in Banking & Financial Services
  • Head of IT Risk & Cybersecurity
  • AVP Data Architecture
  • Lead AI/ML Engineer
  • Head of Compliance & DPO
  • Senior Credit Analyst
  • Head of Digital Banking Engineering
Outcomes commonly requested in Banking & Financial Services
  • Credit analysts & compliance can query policies with answers cited to specific clauses/documents
  • Per-chunk data classification applied: public / internal / restricted / confidential enter separate indexes with different ACLs
  • IT risk teams have a RAG-architecture mapping to POJK 11 and SEOJK 29
  • Vector store monitored like a production database: access, refresh, backup, retention
  • No customer data enters a public embedding model without masking / tokenisation
Banking & Financial Services-specific questions
Can this RAG run on-premise or in the bank's private cloud?
Yes. The deployment module covers fully on-prem options (self-hosted vector DB such as Qdrant or pgvector + local embedding models such as multilingual BGE) and private-VPC options with Azure OpenAI / Bedrock endpoints. Selection depends on the bank's data residency assessment.
How do we align RAG with POJK 11/POJK.03/2022?
We map RAG components (ingestion, index, retrieval, generation, observability) to POJK 11 IT risk articles: governance, change management, information security, business continuity. Training output includes architecture diagrams + RACI attachable to internal audit (SKAI) working papers.
Can Neksus pass bank vendor onboarding (RAS, NDA, vendor KYC)?
Yes. Neksus is used to bank RAS, NDA signing, and providing vendor KYC documents (deed, NPWP, domicile certificate, team profile, lightweight BCP). PPN invoicing and Indonesian bank contract formats supported.

Quick Answer

Enterprise RAG training is an engineering program that builds end-to-end retrieval-augmented generation over corporate corpus: chunking, embeddings, vector DB (Pinecone/Weaviate/Qdrant/pgvector), LangChain/LlamaIndex orchestration, RAGAS & TruLens evaluation, plus OWASP LLM Top 10 2025, NIST AI RMF GenAI Profile, and UU PDP hardening.

Without structured evaluation, RAG is only 'feels right'

RAG demos look convincing; production RAG demands proof. A golden eval set, RAGAS faithfulness/context precision, and regression tests before release are the foundation so retriever or prompt changes do not silently degrade quality. This program installs the evaluation foundation on day one.

Security mapped to OWASP LLM Top 10 2025

Security module mapped explicitly to OWASP LLM01 prompt injection, LLM06 sensitive information disclosure, LLM08 vector & embedding weaknesses, and LLM09 misinformation β€” plus NIST AI RMF GenAI Profile (NIST AI 600-1) and UU PDP.

Most common mistake: jumping to vector DB without chunking & evaluation

Many teams busy themselves picking a vector database then become disappointed when answer quality stays low. Proper chunking, corpus-fit embedding, and a golden eval set matter more than DB choice. This program puts the right priority order in place.

RAG & Knowledge-Base Build Training for LLM Applications

Enterprise RAG training is a technical program that equips engineering, data, and product teams to build retrieval-augmented generation for corporate LLM applications β€” from document chunking strategy, embedding model selection, indexing on vector databases (Pinecone, Weaviate, Qdrant, pgvector), LangChain/LlamaIndex orchestration, through quality evaluation with RAGAS and TruLens, with risk controls mapped to OWASP LLM Top 10 2025, NIST AI RMF GenAI Profile (NIST AI 600-1), and the obligations of Indonesia's Personal Data Protection Law (UU PDP No. 27/2022).

1Grounded in the seminal paper 'Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks' (Lewis et al. 2020) and current production practice of LangChain/LlamaIndex
2Covers the four RAGAS evaluation pillars: faithfulness, answer relevancy, context precision, context recall β€” plus TruLens triad monitoring
3Explicit mapping to OWASP LLM Top 10 2025: LLM01 prompt injection, LLM06 sensitive information disclosure, LLM08 vector & embedding weaknesses, LLM09 misinformation/hallucination
4Advanced chunking strategies: fixed-size, sentence/paragraph, semantic chunking, parent-document, recursive character splitter
5Case studies drawn from your own corpus (policies, SOPs, tickets, product docs) β€” never generic
6Measurable outputs: one ready-to-iterate RAG prototype, golden eval set, RAGAS dashboard, and production blueprint

Program Format

Program Format Options

Selected by team maturity, corpus complexity, and deployment target β€” finalised after TNA.

RAG Engineering Intensive (4-5 days)

Complete deep dive: advanced chunking, hybrid search (BM25 + dense), rerankers, multi-vector retrieval, RAGAS + TruLens evaluation, observability, and OWASP LLM hardening.

Best for: Engineering/data/product teams building production internal assistants
3

Modular RAG Bootcamp (6-8 sessions)

Weekly sessions with experimentation gaps between: participants practice, return with results, get reviewed before the next session. Designed for teams who cannot leave operations.

Best for: Engineering teams with heavy operational load
4

RAG Maturity Program (3-4 months)

Continuous program with office hours, code review, and quarterly maturity checkpoints β€” until RAG ships to production with maintained SLA and observability dashboards.

For Whom

Who This Program Is For

Engineer-grade β€” participants assumed to have basic Python and LLM API familiarity. TNA maps baseline so content stays relevant.

ML/AI Engineer & Data Scientist

Build end-to-end RAG pipelines from ingestion through observable production evaluation.

Common challenges

  • RAG prototype works in notebook, quality drops on real corpus
  • No way to measure RAG quality beyond 'feels right'
  • Vector DB & embedding choices follow tutorials, lack independent criteria

Software Engineer & Platform Engineer

Integrate RAG into internal applications, manage deployment, observability, and SLA.

Common challenges

  • Uncontrolled RAG latency, LLM API costs leaking
  • No CI/CD for prompt & retriever changes
  • Audit log & citation not sufficient for security review

AI Product Manager / Tech Lead

Select viable RAG use cases, set quality criteria, balance cost vs value.

Common challenges

  • Hard to judge which use case fits RAG vs prompt-only vs fine-tune
  • No evaluation framework presentable to leadership
  • Vendor lock-in on a single framework/DB without exit strategy

Security, Data Governance & Legal

Ensure corpus, indexes, and answers comply with security policies, data privacy, and sector regulations.

Common challenges

  • Vector store becomes shadow database without data classification
  • No mapping to OWASP LLM Top 10 2025 or NIST AI RMF
  • UU PDP β€” right to erasure & data minimisation not translated to RAG architecture
