What SISA Information Security does
SISA Information Security is a Bengaluru-headquartered, India-domiciled cybersecurity firm specializing in the payment ecosystem. Founded in 2003 and active in payment breach response since 2006, the company has investigated 1,100+ payment breaches and claims to have secured $1.6 trillion in digital transactions. It serves issuers, acquirers, networks, processors, merchants, and payment service providers, with secondary reach into financial institutions, enterprises with data privacy obligations, and technology companies requiring security testing. Operations span India, USA, Canada, the Middle East, Singapore, Malaysia, the UK, and Australia via direct enterprise field sales and a 24/7 breach hotline. Headcount sits in the 251–500 range and the company is privately held, with founder Dharshan Shanthamurthy as CEO and Ravi Lingarkar as Chief Product and Engineering Officer.
The product portfolio centers on the SISA One Platform — a unified compliance, security, and privacy environment that combines the OneLens™ visibility dashboard, SISA Cyber Index scoring, ProACT Agentic SOC (an AI-powered MXDR service using autonomous agents), the PRISM validation suite (Observe, Discovery, Secure, Strike), and SISA Radar for PCI/PII/PHI data discovery. Around this platform, SISA delivers professional services including PCI DSS, SWIFT, HIPAA, ISO, SOC, HITRUST, NIST, and DPDPA compliance; digital forensics and incident response (DFIR) retainer services; security testing (application, cloud, infrastructure, red teaming, IoT, adversary simulation); and emerging quantum security advisory. SISA Institute runs CPISI and adjacent payment-data-security training and certifications.
The business model blends professional services (compliance audits, security testing, DFIR investigations) with recurring managed services (MXDR via ProACT SOC, DFIR retainers, managed compliance) and subscription-style training revenue through SISA Institute. Stacked accreditations — CREST, SWIFT, CERT-In empanelment, and PCI Security Standards Council Payment Forensic Investigator status — underpin the regulatory credibility required to serve the payments vertical. Revenue is not publicly disclosed and no funding rounds are on record; the company is recognized as Overall Leader in KuppingerCole Analysts Leadership Compass for Managed Detection and Response 2026.
