Founder & Director · VISTA InfoSec · QSA | PA-QSA | PCIP
Narendra Sahoo has spent over three decades at the senior end of one of the most consequential decisions an organization makes: how seriously it takes security.
As Founder and Director of VISTA InfoSec, he advises boards and executive leadership on compliance, risk governance, and security strategy — across industries where the regulatory bar is high and the tolerance for failure is low.

The organizations that engage Narendra are not looking for a compliance checkbox. They are managing real exposure — to regulators, to customers, to the financial and reputational consequences of getting security wrong at scale.
His practice spans the full breadth of the international compliance landscape: PCI DSS, ISO 27001, SOC 2, GDPR, SWIFT CSP, NIST CSF, and the sector-specific frameworks that govern financial services, healthcare, and critical infrastructure globally. As a Qualified Security Assessor and PCI SSA authorized by the PCI Security Standards Council, he brings formal assessment authority to engagements where an internal opinion simply isn’t sufficient.
What distinguishes his approach is a refusal to separate technical substance from strategic consequence. Narendra works at both levels simultaneously — rigorous enough to challenge the controls an organization has built, experienced enough to tell a board precisely what the gaps mean for the business.
Over 30 Years, that combination has made him a trusted voice in boardrooms across financial services, payments, technology, and regulated industries in more than 15 countries.
As a Qualified Security Assessor (QSA) and PA-QSA, Narendra leads comprehensive PCI DSS engagements — from scoping and gap analysis through full ROC assessment — for merchants, service providers, and payment processors globally. Deep fluency in v4.0’s new requirements and customized approach.
Board-level advisory on enterprise security risk — translating technical vulnerability landscapes into strategic business risk narratives. Frameworks include NIST CSF, ISO 31000, and custom governance models for regulated industries.
End-to-end compliance programs for GDPR, India’s DPDP Act, PDPA (Singapore/Thailand), and other regional privacy frameworks. From Data Protection Impact Assessments to DPO advisory and breach response protocols.
Structuring and overseeing comprehensive Vulnerability Assessment and Penetration Testing programs — with rigorous scoping, methodology selection, and actionable remediation roadmaps tied to business risk.
Building vendor risk management programs that go beyond questionnaires — to continuous monitoring, contractual security obligations, and supply chain risk reduction across complex multi-vendor ecosystems.
