What Is Application Security?
Application security is the practice of protecting software applications from vulnerabilities, misuse and attack throughout their lifecycle. It combines security requirements, secure design, code-level controls, testing, vulnerability management and operational safeguards.
Varutra's application security services assess applications from multiple perspectives: what an attacker can reach, what an authenticated user can access, what business rules permit, what the application trusts, and how security is implemented in code and architecture.
Application Vulnerability Assessment
- Discover application, endpoint and attack-surface weaknesses
- Assess authentication, authorization, session and input-validation controls
- Identify security misconfigurations and sensitive-data exposure
- Prioritize findings by severity, exploitability and business impact
Application Penetration Testing
- Manually validate significant vulnerabilities
- Test business logic and privilege boundaries
- Demonstrate realistic attack paths within approved scope
- Provide evidence-based remediation and retesting
What Are the Common Application Security Risks?
Application security testing identifies vulnerabilities that can enable unauthorized access, data breaches, fraud, service disruption and business compromise.
Broken Access Control
Attackers bypass authorization to access restricted accounts, records or functions, potentially causing data theft and privilege escalation.
Authentication & Session Attacks
Weak login, MFA, password and session controls can enable account takeover, impersonation and unauthorized access.
Injection & Data Exposure
SQL injection, command injection and insecure data handling can expose sensitive information or enable unauthorized system access.
Business Logic Flaws
Abusable workflows, transaction manipulation and race conditions can lead to fraud, financial loss and unauthorized actions.
API Security Vulnerabilities
Insecure APIs can expose sensitive data, bypass authorization, enable abuse and compromise connected applications and services.
Security Misconfiguration
Insecure configurations, exposed services, verbose errors and unsafe defaults can reveal attack paths and increase breach risk.

Web Application Security Testing
Web Application Security Testing identifies and validates vulnerabilities across internet-facing, internal, SaaS and enterprise web applications before attackers can exploit them.
Varutra combines automated vulnerability scanning with expert-led manual testing to uncover business logic flaws and security weaknesses that conventional scanners may miss. Assessments cover authentication, authorization, session management, access control, privilege escalation, injection, XSS, file uploads, security misconfigurations, cryptography, server-side and client-side vulnerabilities, data exposure and OWASP Top 10 risks.
Mobile Application Security Testing
Mobile Application Security Testing protects Android and iOS applications handling sensitive customer, employee and business data across the application, device, backend APIs and communication channels.
Our assessments combine static, dynamic and runtime analysis to evaluate application binaries, local data storage, authentication and authorization, cryptography, certificate validation, API communication, reverse-engineering resistance, runtime protections, inter-process communication, deep links, URL schemes, WebViews, secrets, root/jailbreak detection and tamper protection.
Secure Code Review
Source Code Security Review identifies vulnerabilities at the code level that may be difficult to detect through black-box application security testing alone.
Varutra combines automated analysis with expert manual review of authentication and authorization logic, input validation, cryptographic implementations, secure error handling, session management, sensitive data handling, secrets and credentials, injection vulnerabilities, insecure APIs, business logic, security controls and third-party libraries or dependencies.
API Security Testing
API Security Testing identifies vulnerabilities across the REST, SOAP, GraphQL and other APIs powering modern digital platforms, applications, mobile clients and third-party integrations.
Testing focuses on API authentication and authorization, Broken Object Level Authorization (BOLA), Broken Function Level Authorization (BFLA), excessive data exposure, rate limiting and abuse controls, input validation, injection, parameter manipulation, JWT and token security, OAuth/OIDC implementation, API business logic, mass assignment, GraphQL security and API gateway or configuration weaknesses.
Thick Client Security Testing
Thick Client Security Testing assesses desktop applications that perform significant processing or store application components locally. Testing can examine local storage, authentication, update mechanisms, client-side controls, inter-process communication, configuration, binaries and server-side interactions.
The assessment helps identify vulnerabilities where sensitive logic, credentials, data or trust decisions are exposed on the client or where client controls can be bypassed.
Thin Client Security Testing
Thin Client Security Testing focuses on applications where most processing and data handling occurs on remote servers, with the client primarily providing a presentation or access layer.
Testing can examine authentication, session handling, authorization, client-server communication, exposed interfaces, configuration and the security boundaries between the client, application services and backend systems.
Secure Architecture Review
Application Security Architecture Reviews identify design-level security risks before implementation by evaluating application architecture, trust boundaries, data flows, identities, integrations and security controls.
Reviews cover authentication and authorization architecture, identity integration, API architecture, encryption, secrets management, session architecture, microservices and cloud architecture, third-party integrations, security monitoring and logging, resilience and abuse controls.
Secure SDLC Implementation
Secure Software Development Lifecycle (Secure SDLC) integrates security into application requirements, design, development, testing, release and maintenance to identify and address security risks throughout the software lifecycle.
Varutra helps organizations establish security requirements, threat modeling, secure architecture practices, secure coding standards, application security testing and security governance across the software development lifecycle. Our Secure SDLC assessments and implementation support can include SAST, DAST, software composition analysis (SCA), secrets management, security defect management, security testing processes and application security controls aligned with business and regulatory requirements.
Cloud-Native & Container Application Security
Cloud-Native Application Security addresses modern attack surfaces across containers, Kubernetes, microservices, APIs, cloud applications and CI/CD pipelines.
Our assessments identify security weaknesses across container images, Kubernetes configurations, microservices, cloud application architecture, APIs, secrets management, IAM and access controls, Infrastructure-as-Code, CI/CD security, runtime environments and configuration. This helps organizations secure applications across the cloud-native stack.
Application Security Posture Management (ASPM)
Application Security Posture Management (ASPM) provides unified visibility across fragmented application security tools, findings and application assets throughout the software lifecycle.
We help organizations discover applications and assets, consolidate and deduplicate security findings, correlate vulnerabilities across tools, prioritize risks using business context, identify exploitable attack paths and track remediation. ASPM capabilities also support application-level risk scoring, security posture measurement and executive-level application security dashboards.
