Cybersecurity for BFSI in India
Indian banks, NBFCs, payment companies, insurers and capital-market firms face the most prescriptive cybersecurity regulation in the country — RBI Cyber Security Framework, SEBI CSCRF, IRDAI Information & Cyber Security Guidelines, NPCI mandates and the DPDP Act. NexaSource designs, deploys and runs the full security stack required to meet these obligations, with India-resident telemetry and senior architects who have spent years inside Indian financial institutions.

Regulatory frameworks we map to
RBI Cyber Security Framework
Annexes to the 2016 master direction, IT Outsourcing 2023, IT Governance 2023, Digital Lending 2022 — full control mapping for SCBs, UCBs, NBFCs, payment system operators.
SEBI CSCRF
SEBI Cyber Security & Cyber Resilience Framework for stock exchanges, depositories, clearing corporations, AMCs and Qualified RAs — implementation, audit-readiness, and continuous compliance.
IRDAI Cyber Security Guidelines
2017 IRDAI directions and subsequent updates — Information & Cyber Security policy, ISMS, third-party risk, breach reporting timelines.
NPCI & PCI DSS
UPI, IMPS, AePS member-bank security mandates plus PCI DSS v4.0 scoping for card-acquiring and issuing environments.
DPDP Act 2023 & CERT-In
Data principal rights, breach notification, consent architecture, and 6-hour CERT-In incident reporting workflow.
ISO 27001 / SOC 2
For overseas auditors, parent-bank reviews and fintech partnerships — full implementation and recertification support.
BFSI-specific security capabilities we deploy
- Fraud-detection & transaction monitoring: Tuning of UEBA, behavioural analytics, and rule-engine integration with core banking, treasury and payments switches.
- Privileged Access Management (PAM): CyberArk, Delinea, BeyondTrust deployments for core banking, SWIFT, treasury, mortgage origination and policy administration systems.
- Data Loss Prevention (DLP): Endpoint, email, network and cloud-channel DLP — fingerprinted policies for KYC documents, account statements, claim files, policy data.
- SWIFT CSP compliance: CSCF v2024 control implementation and self-attestation support for member institutions.
- Application security: SAST, DAST, SCA, API security gateways and bot mitigation for retail-banking apps, broking platforms and insurance portals.
- Cloud security: CSPM/CWPP for AWS/Azure/OCI — common in cards, lending, insurance-tech and broker-tech stacks.
Threat patterns we are seeing in Indian BFSI (2025-2026)
Mule-account and money-mule rings
Co-ordinated abuse of account-opening flows in small-finance banks and payments companies. Mitigation: device fingerprinting, behavioural biometrics, and graph-based mule detection.
Customer-facing phishing & SIM swap
Continued growth of voice-based social-engineering targeting retail customers. Mitigation: customer-channel monitoring, takedown services, and step-up authentication for high-risk transactions.
Third-party / fintech-partner intrusions
Intrusions into fintech aggregators that cascade into partner banks via shared APIs. Mitigation: API gateway with anomaly detection, vendor risk reviews, and dedicated partner-network segments.
Insider data exfiltration in operations centres
Photo capture of customer data on screens in BPO and KPO operations. Mitigation: image-based DLP, virtual-desktop hardening, and continuous user behaviour analytics.
Where we typically engage
- Universal banks & small-finance banks — RBI CSF refresh, SOC build-out, fraud platform tuning
- NBFCs & HFCs — RBI Scale-Based Regulation security requirements, lending platform hardening
- Insurance & reinsurance — IRDAI ISMS, claims-data DLP, third-party hospital network security
- Asset management & wealth — SEBI CSCRF, treasury and trading desk segmentation
- Stock-broking, depository participants & RIA platforms — Qualified-RA tier security stack, exchange-link hardening
- Payment aggregators, PA-PG, PPI issuers — PCI DSS v4, NPCI partner audits, UPI fraud monitoring
Frequently Asked Questions
Are you empanelled with the RBI?
NexaSource works as a security implementation partner alongside CERT-In empanelled auditors. We coordinate the entire control implementation, then hand off audit evidence to your empanelled auditor — many of whom we work with regularly.
Can you operate inside our premises for SWIFT or core-banking work?
Yes. We routinely embed engineers on-site for SWIFT CSP, core-banking integration, and treasury-room deployments. Background checks and confidentiality agreements are standard.
Where is the SOC telemetry stored?
India by default. We use Indian regions of AWS, Azure or on-prem SIEM clusters depending on your data-residency policy. Telemetry never leaves India unless your group policy explicitly requires otherwise.
Do you support cooperative banks and small UCBs?
Yes — we have a fixed-scope RBI CSF baseline package designed for UCBs and small co-operatives, covering the highest-impact controls within a defined timeline and budget.
How fast can you deliver an RBI gap assessment?
Four weeks for a typical mid-sized bank or NBFC. Output includes a control-by-control gap report, prioritised remediation roadmap, and quick-win control catalogue.
Can you integrate with our existing fraud platform (FRMS / EFRMS)?
Yes — we routinely tune Clari5, Bottomline, NICE Actimize, FIS, and SAS Fraud Management. We integrate them into broader SOC workflows and SOAR playbooks.
