At Harwani Systems (OPC) Private Limited (HSOPC), our cybersecurity focus is built around application architecture, solution architecture, API security, Identity & Access Management (IAM), cloud/platform architecture, secure software engineering, and Zero Trust principles.

Rather than positioning ourselves as a traditional Security Operations Center (SOC) or continuous log-monitoring provider, we focus on engineering security into applications, APIs, platforms and enterprise architectures from the design stage onward.

Our approach brings together:

Architecture + Application Security + API Security + IAM + Cloud Security + DevSecOps + Zero Trust + Open Source Security

We help organizations identify and reduce security risks at the architecture and design layers.

Our work can include:

• Application security architecture reviews
• Secure solution architecture
• Architecture threat modelling
• Trust-boundary identification
• Attack-surface analysis
• Secure application decomposition
• Authentication and authorization architecture
• Session-management architecture
• Secure integration patterns
• Data-flow security reviews
• Encryption architecture
• Secrets-management design
• Multi-tenant security architecture
• Secure microservices architecture
• Security design reviews before production deployment

The objective is simple:

Find architectural weaknesses before they become production vulnerabilities.

Modern enterprises increasingly operate through APIs connecting applications, mobile platforms, cloud services, partners, AI systems and external ecosystems.

HSOPC helps organizations design and review APIs from a defensive-security perspective.

• REST API security
• Microservices security
• API gateway architecture
• Authentication and authorization
• OAuth 2.0
• OpenID Connect (OIDC)
• JWT security
• Token lifecycle management
• API key management
• Service-to-service authentication
• Rate limiting and throttling
• Input validation
• API access policies
• API exposure assessment
• API versioning and lifecycle security
• North-South and East-West API security
• Third-party API integration security
• Machine-to-machine identity
• API security architecture for AI and agentic systems

We can also review architectures against relevant OWASP API Security principles and industry security practices.

Identity is increasingly becoming one of the primary security boundaries of modern enterprise systems.

HSOPC's IAM work focuses on designing and reviewing identity architecture across applications, APIs, cloud platforms and enterprise systems.

• Identity architecture assessment
• Authentication architecture
• Authorization architecture
• Single Sign-On (SSO)
• Multi-Factor Authentication (MFA)
• Federation architecture
• Identity-provider integration
• Role-Based Access Control (RBAC)
• Attribute-Based Access Control (ABAC)
• Policy-Based Access Control
• Least-privilege architecture
• Privileged-access architecture
• Service identities
• Workload identities
• Machine identities
• API identities
• Identity lifecycle architecture

Architectures may incorporate standards and technologies including:

• OAuth 2.0
• OpenID Connect
• SAML
• JWT
• SCIM
• PKI
• Certificates
• Secrets and key management

Traditional security models frequently assumed that systems operating inside an enterprise network could be trusted.

Modern distributed architectures require a different approach.

HSOPC can help organizations design architectures around the principle:

Never trust implicitly. Continuously verify identity, authorization and context.

Our Zero Trust architecture work can cover:

• Identity-centric security
• Application-level authorization
• API-level authorization
• Service-to-service authentication
• Workload identity
• Micro-segmentation architecture
• Least-privilege access
• Device and workload trust
• Policy enforcement points
• Secure service communication
• Secrets and credential management

Cloud security should be incorporated into platform architecture rather than added after deployment.

HSOPC can review and design security controls across:

• Public cloud
• Private cloud
• Hybrid cloud
• Kubernetes
• Containers
• Virtual machines
• Application platforms
• Middleware
• Databases
• API gateways
• Open-source infrastructure

• Cloud security architecture
• Network segmentation
• IAM architecture
• Workload identity
• Container security architecture
• Kubernetes security architecture
• Secrets management
• Certificate management
• Encryption architecture
• Secure ingress/egress design
• Service-to-service security
• Administrative-access architecture
• Secure configuration baselines
• Infrastructure-as-Code security principles

Security should become part of the software engineering lifecycle rather than a final-stage audit activity.

HSOPC can help organizations introduce security controls across the Software Development Lifecycle (SDLC).

Architecture → Development → Build → Test → Deploy → Operate

Security activities may include:

• Secure architecture reviews
• Threat modelling
• Secure coding practices
• Dependency-security strategy
• Software Composition Analysis (SCA)
• Static Application Security Testing (SAST)
• Dynamic Application Security Testing (DAST)
• Container image scanning
• Secrets scanning
• Infrastructure-as-Code scanning
• CI/CD security controls
• Artifact and repository security
• Software supply-chain security
• SBOM adoption
• Deployment security gates

The goal is to move security controls earlier into architecture and engineering workflows.

Threat modelling helps engineering teams systematically understand how an application could be attacked before those weaknesses are exploited.

A typical HSOPC assessment can examine:

Users / External Systems
↓
Web / Mobile / Client Layer
↓
API Gateway / Edge Layer
↓
Identity & Access Layer
↓
Application / Microservices Layer
↓
Data & Integration Layer
↓
Cloud / Platform Infrastructure

At every layer we evaluate:

• Assets
• Actors
• Entry points
• Trust boundaries
• Authentication
• Authorization
• Data flows
• Secrets
• External dependencies
• Potential attack paths
• Security controls

Threat-modelling approaches can incorporate established frameworks such as STRIDE, attack trees and architecture-centric risk analysis.

Open-source software forms a major part of modern enterprise infrastructure.

HSOPC combines its open-source and enterprise architecture capabilities with security engineering.

Areas may include:

• Open-source architecture security reviews
• Dependency governance
• Vulnerability-management architecture
• Software Composition Analysis
• SBOM strategy
• Container security
• Secure middleware configuration
• Secure web-server architecture
• Database security architecture
• Open-source IAM architecture
• API gateway security
• Kubernetes security
• Secure configuration baselines

Typical technology environments may include platforms and technologies such as:

Linux | Kubernetes | Docker | Apache | NGINX | Tomcat | Java | Spring | Liferay | PostgreSQL | MySQL | Kafka | Elasticsearch / OpenSearch

AI introduces additional security boundaries involving models, data, APIs, tools, agents and enterprise systems.

HSOPC can extend its architecture-led security approach to:

• GenAI application architecture
• LLM application security
• RAG architecture security
• Agent authentication
• Agent authorization
• API and tool permissions
• Secrets isolation
• AI gateway architecture
• Model/API access control
• Data-access boundaries
• Agent-to-agent trust
• Human-in-the-loop controls
• Prompt and context security
• AI workload identity
• Least-privilege agent design

The principle remains the same:

AI agents should receive only the identities, permissions, tools and data required to perform their intended functions.

Organizations can engage HSOPC for independent architecture-level assessments.

Review of application architecture, components, interfaces, identities, data flows and security boundaries.

Assessment of API exposure, authentication, authorization, gateway architecture, tokens, service identities and integration security.

Assessment of authentication, federation, authorization, identity lifecycle, privileged access and machine identities.

Assessment of cloud workloads, IAM, segmentation, secrets, containers, Kubernetes and platform architecture.

Assessment of security controls across source code, CI/CD pipelines, dependencies, artifacts and deployment processes.

Evaluation of existing enterprise architecture and development of a roadmap toward identity-centric and least-privilege security.

HSOPC's Blue Team positioning emphasizes preventive and engineering-led defensive security.

Our focus is primarily:

Build systems with defensible architectures.

↓

Reduce attack surfaces and excessive privileges.

↓

Apply identity, API, application, platform and data security controls.

↓

Validate architecture and security assumptions through reviews, testing and automated security checks.

↓

Feed security findings back into architecture, engineering and DevSecOps practices.

We do not primarily position HSOPC as a traditional:

• 24×7 Security Operations Center (SOC)
• Managed SIEM provider
• Security-event monitoring provider
• Log-monitoring service
• Tier-1/Tier-2 SOC alert-triage operation

Where customers require these capabilities, HSOPC's architecture and engineering services can complement specialist SOC, MDR, SIEM and incident-response providers.

Security cannot depend entirely on detecting an attacker after something has gone wrong.

Strong defensive security begins much earlier:

Architecture → Identity → APIs → Applications → Data → Platform → Cloud → Deployment → Operations

HSOPC therefore approaches cybersecurity as an architecture and engineering discipline.

Our objective is to help enterprises build systems that are:

Secure by Design | Identity Aware | API Secure | Least Privilege | Zero Trust | Cloud Native | Observable | Resilient | Governable

HSOPC's differentiator is the intersection of cybersecurity with our broader technology capabilities:

Enterprise Architecture

• Solution Architecture
• Application Architecture
• Open Source Technologies
• API & Integration Architecture
• IAM
• Cloud & Platform Engineering
• AI / GenAI
• Data Engineering
• DevSecOps
  =
  Architecture-Led Cybersecurity Engineering

This allows security decisions to be considered as part of the overall enterprise and technology architecture, rather than as an isolated operational function.

Organizations can engage HSOPC for:

• Security architecture advisory
• Application architecture security reviews
• API security assessments
• IAM architecture assessments
• Zero Trust architecture
• Cloud/platform security architecture
• DevSecOps transformation
• Secure SDLC design
• Threat-modelling workshops
• AI/GenAI security architecture
• Open-source security architecture
• Independent architecture reviews
