Find Vulnerabilities Before Attackers Do

Across Code, APIs, Web, and Mobile

Most security breaches don't exploit exotic zero-days. They exploit vulnerabilities already in your application: a configuration file, an unvalidated input field, a misconfigured API endpoint, or a third-party dependency your team forgot about.

Our application security testing services systematically identify vulnerabilities across your entire application surface before they become incidents. We combine static application security testing (SAST), dynamic application security testing (DAST), and manual penetration testing to give your engineering, security, and compliance teams the full picture.

Static Application Security Testing (SAST) Services

White-box testing that involves a deep-dive analysis of your application’s source code, binaries, or bytecode.

Dynamic Application Security Testing (DAST) Services

A black-box testing approach that involves testing the application from the outside in while it is running in a staging or production-like environment.

Manual Application Penetration Testing Services

Going beyond automated tools, our application penetration testing services involve expert ethical hackers who attempt to bypass your security controls.

Our Services

End-to-End Application Security Testing Services

Every service below involves hands-on work and validation by our security engineers, not just automated tool output. Findings are triaged and delivered in formats your developers and security teams can actually use.

Consulting

Application Security Strategy and Consulting

Our application security testing company provides the strategic governance and architectural oversight needed to transform security from a reactive bottleneck into a proactive business enabler. We embed security directly into the development lifecycle, ensuring compliance and risk reduction are automated and measurable.

Static Application

Static Application Security Testing Services (SAST)

Our static application security testing company surfaces issues such as SQL injection, cross-site scripting, insecure cryptography, hardcoded credentials, and vulnerable dependency usage early in the SDLC, where remediation costs a fraction of what they do in post-production.

  • Source code analysis across Java, Python, JavaScript, TypeScript, etc
  • IaC security scanning (Terraform, CloudFormation, Helm, and Kubernetes manifests)
  • Dependency and third-party library vulnerability analysis (SCA)
  • Hardcoded secret and credential detection across repositories
  • CI/CD pipeline integration with IDE plugins and PR-level feedback for developers
  • OWASP Top 10, CWE/SANS Top 25, and NIST-aligned finding classification
Dynamic

Dynamic Application Security Testing Services (DAST)

Dynamic application security testing tests your application as it runs, sending crafted inputs, manipulating requests, and observing responses to surface vulnerabilities that static analysis cannot detect. We cover the full OWASP API and Web Application Top 10 to reflect real attack conditions.

  • Authentication and session management vulnerability testing
  • Injection flaw detection (SQL, LDAP, XML, command, and template injection)
  • Business logic vulnerability identification
  • CORS misconfiguration, security header analysis, and cookie attribute validation
  • API-specific testing (mass assignment, BOLA, and rate limiting gaps)
  • Integration with JIRA, GitHub Issues, and security platforms
Web Application

Web Application Security Testing Services

Our web application testing services combine rigorous discovery with manual expertise to detect complex vulnerabilities, chain low-severity findings into high-impact attack paths, and validate every threat before providing a remediation roadmap.

  • Full OWASP Testing Guide (OTG) methodology 
  • Authentication bypass, privilege escalation, and session hijacking testing
  • Business logic abuse (pricing manipulation, workflow bypass, etc)
  • File upload, deserialization, and SSRF testing
  • Third-party integration and OAuth flow security review
  • Detailed findings report with CVSS scores and remediation guidance
Mobile Application

Mobile Application Security Testing Services

Mobile applications present a distinct attack surface: local data storage, inter-process communication, certificate handling, and binary protections all require dedicated assessment. We cover both static analysis of the application binary and dynamic testing on a live device or emulator, providing complete coverage of the OWASP Mobile Security Testing Guide (MSTG).

  • Static binary analysis of hardcoded credentials
  • Dynamic testing (runtime analysis, traffic interception, etc)
  • Local data storage assessment (SQLite exposure, shared preferences, keychain misuse, etc)
  • Certificate pinning validation and SSL/TLS interception testing
  • Inter-process communication (IPC) and deep link vulnerability testing
  • Platform-specific testing (iOS Keychain, Android Keystore, biometric authentication flows)
API Security

API Security Testing

APIs are now the primary attack surface for web and mobile applications, yet most organizations test them less rigorously than their frontends. Our software security testing service covers the full OWASP API Security Top 10, including broken object-level authorization, excessive data exposure, and security misconfiguration.

  • REST, GraphQL, SOAP, and gRPC/tRPC API security assessment
  • Broken object-level and function-level authorization testing
  • Mass assignment and parameter tampering across API endpoints
  • Authentication mechanism review
  • Rate limiting, throttling, and resource consumption abuse testing
  • API documentation review and attack surface mapping
Security Integration

DevSecOps and CI/CD Security Integration

Security testing that only runs before release is already too late. We embed static and dynamic application security testing into your existing DevOps and CI/CD pipelines. Our QA automation engineers configure tools, setting severity thresholds, and defining developer-facing feedback loops that make security a first-class part of every build.

  • SAST tool selection, configuration, and pipeline integration
  • DAST integration into staging pipelines
  • Software composition analysis (SCA)
  • Security gate configuration
  • Developer-facing security dashboards and IDE plugin setup
  • Security champion training and secure code review process design

Move Beyond "Checking the Box" on Security

Manual reviews and periodic audits are no longer enough to protect modern applications. Our application security testing company helps you build a continuous, automated, and high-assurance defense-in-depth strategy.

SAST vs. DAST: What Each Finds

And Why You Need Both

Static application security testing and dynamic application security testing answer different questions about your application's security. Neither is a substitute for the other.

Used together, they cover the full vulnerability lifecycle, from insecure code patterns to runtime exploitation paths.

Static Application Security Testing (SAST) Dynamic Application Security Testing (DAST)
When it Runs Before execution, on source code, bytecode, or binaries Against a running application in a test or staging environment
What it Finds Insecure code patterns, hardcoded secrets, vulnerable dependencies, and logic errors in code Runtime vulnerabilities, authentication flaws, injection points, and misconfigured server behavior
Blind Spots Cannot detect runtime configuration issues, authentication flows, or server-side behavior Cannot see code-level issues, third-party library flaws, or secrets embedded in source
Best For Early SDLC feedback, developer-facing fixes, CI pipeline integration Pre-release validation, API security, and business logic testing in a live environment

Most compliance frameworks and mature security programs require evidence of both. And that’s what our application security testing company offers. More importantly, we correlate findings across them so you see the full picture, not two disconnected reports.

Application Security Testing: FAQs

Static application security testing analyzes your code without running it. It catches vulnerabilities at the source, early in development. On the other hand, dynamic application security testing tests the running application, finding vulnerabilities that only emerge at runtime. Most organizations need both. Our app security testing company can tailor a hybrid framework for your workflows.

Possibly. However, it depends on how the tool is configured and how findings are being triaged. SAST tools configured out of the box generate significant false positive noise, and teams often have to tune them down to reduce alert fatigue. External static application security testing support brings validated configuration, manual triage of findings, and coverage of vulnerability classes that tools consistently miss.

A scoped web application penetration testing service engagement for a mid-complexity application typically runs a few weeks from kickoff to final report. Larger applications with significant API surface or complex authentication flows may take longer. Contact our web application testing company at info@suntecindia.com for the timeline.

Yes. Our software security testing service configures SAST tools to run on pull requests, DAST tools to run against ephemeral staging environments, and SCA tools to flag vulnerable dependencies on every build. We also define the severity thresholds and developer notification workflows so findings reach the right person in a format they can act on.

It affects scoping, data handling, and reporting, but it doesn't make the engagement impossible or unusually complex. Our application security testing company has experience working in HIPAA-, PCI DSS-, CCPA-, SOC 2-, and GDPR-regulated environments. All engagements are conducted under NDAs/NCAs, and we work with synthetic or masked data in testing environments wherever possible.

Every engagement delivers:

  • A prioritized findings report with CVSS scores, 
  • Detailed reproduction steps, root cause analysis, and developer-ready remediation guidance
  • An executive summary suitable for board or compliance reporting
  • A remediation tracking worksheet
  • A retest engagement to confirm that critical and high findings have been addressed

For organizations that want ongoing coverage, we offer quarterly mobile application testing assessment programs with continuous SAST and DAST pipeline integration.

Vulnerability scanners produce a list of findings. Our application security testing services produce validated, prioritized, and actionable security intelligence. Every automated finding is reviewed by a security engineer before it appears in your report. False positives are removed, severity ratings are adjusted to reflect your actual risk context, and related findings are correlated into attack chains that show the real-world impact.

Start with SAST integrated into your CI pipeline; it's the highest-leverage investment at an early stage because it catches vulnerabilities before they become embedded technical debt. The second priority is an API security assessment if you're exposing APIs to third parties or processing user data. Full web application penetration testing and mobile application security assessment can follow as your application surface and user base grow.
