Web Application Security

Web Security Testing

Enterprise-grade testing for apps, APIs, SaaS & AI features

We proactively identify, assess, and help remediate security risks across modern web applications, APIs, and cloud-native platforms.

What we offer

Our web security testing offerings

Testing methodologies aligned with globally recognised standards — OWASP, ASVS, and NIST — across your full web attack surface.

Continuous Web Security Monitoring

Weekly / Monthly / Annual

Ongoing, scheduled testing that keeps modern web apps protected as code ships and new threats emerge — not just a once-a-year snapshot.

  • Recurring assessments on a weekly, monthly, or quarterly cadence
  • Continuous detection of newly disclosed CVEs in your dependencies
  • Coverage for SPAs and modern JS frameworks (React, Next.js, Vue)
  • Risk-based prioritisation with remediation re-testing
  • Executive and technical reporting for every cycle

Web Application Penetration Testing

OWASP Top 10 · ASVS

Full-scope, manual-led penetration testing that simulates real attackers to uncover exploitable flaws across your entire application.

  • Aligned to OWASP Top 10 (2021) and OWASP ASVS verification
  • Authentication, authorization, and session management testing
  • Business logic and workflow abuse testing
  • Client-side, DOM-based, and access-control attack paths
  • Manual testing combined with tool-assisted techniques

SaaS Application Penetration Testing

Multi-tenant & Cloud-native

Testing focused on the risks unique to cloud-based, multi-tenant SaaS platforms — where one flaw can affect every customer.

  • Tenant isolation and data segregation testing
  • Cloud configuration and IAM access controls
  • Identity, SSO, and federation security
  • Third-party and API integration risk review
  • Privilege escalation and cross-tenant data leakage

API Security Testing

REST · GraphQL · gRPC

APIs are the backbone of modern apps and a top attack vector. We test them against the OWASP API Security Top 10 and beyond.

  • OWASP API Security Top 10 (2023) coverage
  • Broken object/function level authorization (BOLA/BFLA)
  • GraphQL introspection, batching, and injection abuse
  • Rate limiting, mass assignment, and abuse scenarios
  • Secure data handling and excessive data exposure checks

AI & LLM Feature Security

Emerging Threats

As products add AI features, they inherit a new attack surface. We test LLM-powered functionality against modern AI threat models.

  • Prompt injection and jailbreak resistance testing
  • Sensitive data and system-prompt leakage
  • Insecure output handling and downstream impact
  • Model endpoint authentication and authorization
  • Guardrail and content-filter bypass attempts

Targeted & Pre-Release Testing

Focused & Time-sensitive

Fast, focused testing for specific pages, modules, or critical features — ideal before a launch or after a fix.

  • High-risk or newly deployed features
  • Critical payment, login, or admin modules
  • Pre-release and post-fix security verification
  • Time-boxed validations for urgent needs
How we work

Our testing process

A proven, methodical approach that ensures comprehensive coverage and reliable, reproducible results.

01

Define Scope

We align with your stakeholders on application components, environments, testing boundaries, and business-critical functionality.

02

Information Gathering

We map the application, architecture, technologies, and exposed interfaces to understand context and likely attack vectors.

03

Enumeration

We analyse endpoints, roles, APIs, and services to chart the full attack surface and pinpoint exploitable areas.

04

Exploitation

We simulate real-world attacks with manual techniques and tooling to validate the impact and severity of each weakness.

05

Reporting

You receive a detailed report with vulnerability descriptions, risk ratings, proof of concept, business impact, and fixes.

06

Remediation Testing

After fixes are applied, we re-test to confirm vulnerabilities are resolved and no new issues were introduced.

Why it matters

Key benefits

Enterprise application penetration testing delivers value far beyond basic security validation.

Stronger Application Security

Identify and close weak points before attackers exploit them, hardening your apps against real-world threats.

Compliance & Audit Support

Demonstrate due diligence for SOC 2, ISO 27001, PCI-DSS, and DPDPA with independent, evidence-backed testing.

Early Vulnerability Detection

Surface hidden flaws and entry points early, enabling proactive risk mitigation and lower remediation cost.

Secure SDLC Enablement

Actionable findings help developers understand root causes and adopt more secure coding practices over time.

Clear Risk Visibility

Get a prioritised view of your application risk landscape to make informed security decisions.

Third-Party Assurance

Independent reports build trust with customers, partners, and stakeholders who require proof of security.

Methodologies

Types of penetration testing

Multiple methodologies to suit different risk profiles and organisational needs.

Black Box

Zero Knowledge

Simulates an external attacker with no prior knowledge — testing how your app withstands unknown threats.

White Box

Full Knowledge

With full access to code, architecture, and docs, we deep-dive to uncover hidden logic flaws and design weaknesses.

Gray Box

Some Knowledge

A balanced approach replicating a partially informed attacker, combining efficiency with practical depth.
