Anirban Bhattacharjee
With 18+ years of hands-on experience across cybersecurity, IT infrastructure, compliance and enterprise technology, Anirban Bhattacharjee brings a security-first perspective to complex digital environments.
His expertise spans security architecture, regulatory compliance, zero-trust frameworks, threat modelling, cloud security, network security, identity and access management, incident response and audit readiness.
Building Security Into Every Layer
Modern cybersecurity cannot depend on a firewall, endpoint product or isolated security control.
It requires an architecture where identity, network, applications, cloud, endpoints, data and governance work together as one security ecosystem.
Anirban's approach begins by understanding business risk and translating it into practical security controls.
From threat modelling and network segmentation to identity governance and compliance documentation, his focus is on building environments capable of answering three fundamental questions:
At Data Confiance, his approach strengthens the bridge between technology implementation and governance — helping organisations build infrastructure that is not only secure, but also measurable, auditable and aligned with business and regulatory requirements.
Security Across the Technology Stack
Security Architecture
Designing security frameworks aligned with organisational risks, technology environments and business objectives.
Zero Trust & Segmentation
Experience with Zero Trust Architecture, SD-WAN and network segmentation to reduce unnecessary access and limit security exposure.
Network Security
Experience designing firewall policies, VPN environments and IDS/IPS controls using technologies including:
Identity & Access Management
Designing identity governance and access-control environments using technologies such as:
Microsoft Entra ID · Aruba ClearPass
including conditional access, multi-factor authentication, role-based access and dynamic network access controls.
Making Security Defensible
The value of cybersecurity is not simply in having controls.
Organisations must be able to understand why those controls exist, what risks they address, whether they are working and how their effectiveness can be demonstrated.
Anirban brings this governance perspective into technology architecture, helping organisations connect technical implementation with security policy, regulatory requirements and audit expectations.
His experience includes developing audit-ready security portfolios, risk assessments, security documentation and ISO/IEC 27001-aligned frameworks, as well as working across multi-vendor enterprise environments.
