Building Secure Applications that Protect Your Business

Applications power modern businesses – from customer portals and e-commerce platforms to internal tools and SaaS products. But poorly secured applications are one of the biggest entry points for cybercriminals. A single vulnerability in your web or mobile app can expose sensitive data, disrupt services, and damage trust.

At ZealsTECH, our Application Security Services safeguard your applications across their entire lifecycle. From secure coding practices to penetration testing and runtime protection, we ensure your applications are built secure, deployed secure, and remain secure.

Building Secure Applications that Protect Your Business
Why Application Security Matters

Why Application Security Matters

Defend Against Common Attacks

Prevent SQL injections, XSS, CSRF, and more.

Secure SDLC

Integrate security into software development lifecycle.

Protect Sensitive Data

Ensure customer and business information is not exposed.

Meet Compliance Requirements

PCI DSS, SOC 2, ISO 27001, and NIST.

Build Customer Trust

Secure apps enhance user confidence and brand reputation.

Core Security Components We Deliver

01

Secure Software Development Lifecycle (SDLC) Integration

We embed security into every stage of your software development lifecycle.
  • Threat modeling during design phase.
  • Static Application Security Testing (SAST) for source code.
  • Secure coding guidelines for developers.
  • Security gates integrated into CI/CD pipelines.

02

Application Penetration Testing

Simulated real-world attacks to uncover vulnerabilities before attackers do.
  • OWASP Top 10 vulnerability testing (SQLi, XSS, CSRF, SSRF).
  • Manual and automated testing for business logic flaws.
  • API penetration testing for REST and GraphQL endpoints.
  • Detailed remediation reports with proof-of-concept exploits.

03

Web Application Firewall (WAF) Deployment & Tuning

We deploy and fine-tune WAFs to protect web applications from exploitation attempts.
  • Layer 7 traffic filtering.
  • Protection against DDoS, injection, and zero-day attacks.
  • Custom rule sets based on application behavior.
  • Continuous tuning to reduce false positives.

04

API Security

APIs connect modern apps – and they’re often a weak link if left unsecured.

  • OAuth 2.0 / OpenID Connect implementation for secure authentication.
  • Input validation and schema enforcement.
  • Rate limiting and throttling to prevent abuse.
  • API gateway integration with logging and monitoring.

05

Mobile Application Security

We secure mobile apps against data leakage, reverse engineering, and malware.
  • OWASP Mobile Top 10 testing.
  • Secure local data storage (encrypted SQLite, Keychain/Keystore).
  • Root/jailbreak detection and runtime protection.
  • Code obfuscation to prevent reverse engineering.

06

Dynamic Application Security Testing (DAST)

Continuous scanning of running applications to detect vulnerabilities.
  • Black-box testing for deployed applications.
  • Session management and authentication checks.
  • Business logic abuse detection.
  • Integration with CI/CD for ongoing testing.

07

Runtime Application Self-Protection (RASP)

We implement RASP solutions to detect and block attacks from within the application.
  • Real-time detection of malicious inputs.
  • Protection against injection, deserialization, and logic-based attacks.
  • Integration with app runtime for minimal performance impact.
  • Centralized reporting for incident visibility.

08

Software Composition Analysis (SCA)

We scan for risks in open-source libraries and third-party dependencies.
  • Automated detection of vulnerable libraries.
  • Continuous monitoring for newly disclosed CVEs.
  • Version management and patching recommendations.
  • License compliance reporting.
