Top SOC 1 Consultants
in Mumbai (2026)

Mumbai-headquartered Network Intelligence (formerly NII Consulting) is one of the city's longest-standing cybersecurity firms, founded in 2001 with a team of 550+ specialists and offices in New York, Amsterdam, Sydney, Dubai, and Singapore. A large share of its work sits in banking, financial services, and insurance — the exact vertical where SOC 1 matters most. Its compliance practice spans SOC 1, SOC 2, ISO 27001, and PCI DSS, and it increasingly pairs advisory with its Transilience AI automation platform for evidence collection.

Navi Mumbai-headquartered QRC Assurance & Solutions, founded in 2016, is an audit and assessment company that delivers SOC 1, SOC 2, and SOC 3 attestation alongside PCI DSS (as a Qualified Security Assessor) and ISO standards. Its client base is concentrated in payments and IT-services outsourcing — exactly the segments where SOC 1's ICFR focus applies. QRC is CERT-In empanelled and positions itself on consolidating several certifications through a single assessment relationship, which is valuable for Mumbai payment companies that hold both SOC 1 and PCI DSS.

KPMG in India is part of one of the Big Four professional-services networks and runs a large risk advisory and IT audit practice with a major Mumbai presence. Its teams handle SOC 1 readiness, ICFR control design, and SSAE 18 alignment for large enterprises, banks, custodian services, and regulated financial institutions — typically as part of broader internal audit and regulatory programmes. KPMG also fields its own licensed CPA practice, which can issue SOC 1 reports directly for organisations where it is independent.

Bengaluru-headquartered SISA is a forensics-driven cybersecurity company best known in payment security, where it operates as a PCI Qualified Security Assessor and PCI Forensic Investigator for banks and fintechs across 40+ countries, protecting 1,000+ organisations. Its teams bring real breach-investigation insights into control design, which strengthens ICFR controls for payment processors and card-services outsourcers in Mumbai's financial district. SISA pairs SOC 1 readiness with PCI DSS and SOC 2 where multiple frameworks apply.

ControlCase is a US-headquartered compliance-as-a-service company with a significant delivery presence in India. It offers SOC 1 attestation support alongside SOC 2, PCI DSS, ISO 27001, and HITRUST, built around a One Audit model that maps a single evidence set across frameworks — attractive for Mumbai BPOs and service providers facing SOC 1 from their banking clients and PCI DSS from their payments clients simultaneously. Its continuous-compliance tooling layers monitoring on top of point-in-time attestation.

Deloitte India is part of the global Big Four network and maintains a large Mumbai office with dedicated risk advisory, IT audit, and assurance teams. Its SOC 1 practice serves custodian banks, fund administrators, securities back-office outsourcers, and insurance TPAs — institutions where ICFR reporting to user auditors is a contractual requirement. Like KPMG, Deloitte's licensed CPA arm can issue SOC 1 reports directly (where independence rules permit), and its risk advisory teams handle readiness and remediation for clients who need an independent issuer.
