Security Testing Services

Overview

Modern software is built from many moving parts: application code, third-party libraries, identity providers, CI/CD pipelines, containers, cloud services, and integrations with external vendors. Security issues rarely come from a single bug. More often, breaches happen when multiple small weaknesses align—misconfigured access controls, exposed secrets, vulnerable dependencies, missing input validation, insecure API endpoints, or gaps in monitoring. Security testing provides continuous validation against real attack paths so you can reduce breach risk, protect customer data, and meet compliance requirements.

The challenge is that security testing is frequently treated as a late-stage gate. Teams run a scan before release, receive dozens of findings, and struggle to understand what matters. That approach creates friction and “security fatigue.” We deliver security testing as a practical, engineering-friendly program: focused on exploitability and business impact, integrated into the SDLC, and structured to help teams fix issues quickly and prevent regressions.

Global Technology Services supports product teams, enterprise IT departments, and regulated industries that require repeatable security validation, clear reporting, and remediation guidance that developers can implement without slowing delivery. Whether you need a targeted penetration test, a full application security program, or continuous security testing embedded into CI/CD, we structure engagements to produce measurable outcomes: fewer critical vulnerabilities in production, faster remediation cycles, and a sustainable security posture that scales with your organization.

Key Service Areas

Scope

Security testing scope depends on your architecture and threat landscape. A public customer-facing web app has different risks than an internal finance platform; a mobile banking app has different requirements than an API platform for partners. We tailor coverage to match what matters: your data sensitivity, attack surface, compliance obligations, and the real ways attackers would target your system.

1) Penetration Testing for Web Applications

Web applications remain a primary target because they are accessible, often hold valuable data, and frequently change. Our web application penetration testing follows OWASP-aligned practices to identify and validate vulnerabilities. We go beyond simple scanning by confirming exploitability, testing realistic attack chains, and documenting reproduction steps your engineering teams can use.

• Authentication and session management testing (login flows, MFA, password reset)
• Authorization and access control validation (role boundaries, object-level permissions)
• Injection risks (SQL/NoSQL injection, command injection) where applicable
• XSS, CSRF, and client-side risks including modern SPA patterns
• File upload and content handling validation
• Business logic abuse cases (discount manipulation, workflow bypass, fraud scenarios)

2) API Security Testing

APIs power modern digital platforms, but they also expand the attack surface dramatically. Attackers target APIs for data extraction, account takeover, privilege escalation, and abuse of business workflows. We test APIs using an OWASP API Security mindset and validate how endpoints behave under real adversarial conditions, including token misuse, role confusion, and object-level access flaws.

• Endpoint discovery and attack surface mapping
• Authorization validation (BOLA/IDOR patterns, scope issues, role escalation)
• Rate limiting, anti-automation, and abuse protection checks
• Input validation and data exposure validation (over-posting, mass assignment)
• Security testing for integrations with external partners and vendors

3) Mobile Application Security Testing

Mobile apps introduce risks beyond the server: local storage, device-level security, transport security, and tampering. We assess how your mobile application stores data, communicates with backend services, handles authentication, and protects against reverse engineering. The goal is to reduce the risk of data leakage, account takeover, and abuse of mobile-specific attack vectors.

• Secure storage validation (tokens, secrets, sensitive cached data)
• Transport security and certificate handling checks
• Runtime protections and tampering resistance assessment
• Backend API testing through mobile flows
• Recommendations for hardening and secure coding practices

4) SAST: Static Application Security Testing

SAST helps detect insecure code patterns early—before vulnerabilities reach production. We help you select and configure SAST tooling, tune rules to reduce false positives, and integrate scanning into your pull request workflow. We also provide triage guidance so engineers understand findings and fix them efficiently.

• SAST setup and integration into CI pipelines
• Rule tuning and false-positive reduction strategy
• Secure coding recommendations aligned with your tech stack
• Developer-friendly reporting and remediation examples

5) DAST: Dynamic Application Security Testing

DAST validates security from the outside by testing a running application. It’s particularly useful for discovering runtime issues such as misconfigurations, exposed endpoints, or vulnerabilities that only appear in certain environments. We integrate DAST into staging pipelines where feasible, and we provide manual validation to confirm exploitability and impact.

• DAST scanning setup for staging environments
• Authenticated scanning for deeper coverage
• Validation of findings to reduce noise
• Regression scanning to catch reintroduced issues

6) Dependency, SBOM & Supply-Chain Security

Third-party dependencies accelerate development but create supply-chain risk. We help teams identify vulnerable libraries, prioritize remediation based on exploitability and exposure, and establish processes for ongoing dependency hygiene. Where needed, we support SBOM practices so you can track components and respond faster to new vulnerabilities.

• Dependency scanning implementation and tuning
• Prioritization: critical vulns, reachable code paths, and production exposure
• Upgrade planning and remediation validation
• SBOM guidance and operational recommendations

7) Cloud & Configuration Reviews

Many real-world breaches happen due to misconfiguration: overly permissive IAM roles, exposed storage buckets, weak network controls, or secrets stored incorrectly. We review cloud configurations (at the level allowed by your organization) and focus on the controls that protect data and prevent lateral movement.

• IAM design and least-privilege recommendations
• Network segmentation and exposure review
• Storage security and data exposure checks
• Secrets management practices and key rotation guidance
• Container and runtime configuration assessment where relevant

8) Threat Modeling Workshops

Threat modeling helps you prevent vulnerabilities by designing secure controls upfront. We run structured workshops to identify abuse cases, define trust boundaries, and prioritize security controls. This is especially valuable for new systems, major architectural changes, and high-risk integrations (payments, identity, customer data platforms).

• Architecture review, data flow mapping, and trust boundaries
• Threat identification aligned with real adversary behavior
• Control selection: auth, authorization, validation, logging, encryption
• Security backlog creation and ownership definition

9) Security Regression Testing

Security fixes can regress. We define security regression checks for critical controls (authorization rules, input validation, configuration guards) and help teams implement repeatable validation. This can include targeted automated checks, periodic scanning, and re-tests after major changes.

• Security control regression checklist and validation patterns
• Re-test cycles after remediation and releases
• Continuous scanning and alerting integration (optional)

Deliverables typically include an executive summary, a prioritized vulnerability backlog with severity rationale, proof-of-concept evidence (where allowed), and step-by-step remediation guidance. We also provide verification support—re-testing fixes and helping teams confirm that vulnerabilities are resolved without introducing regressions.

Approach

Our security testing process is built to produce fixes—not just findings. We combine tooling with expert validation and focus on outcomes: reduced risk, faster remediation, and sustainable security practices.

Phase 1: Discovery & Scoping

We define the rules of engagement and gather the information needed for effective testing: assets, environments, credentials, data handling requirements, and target risks. We also clarify expectations—what success looks like, how findings will be prioritized, and how remediation support will be delivered.

• System inventory and architecture overview
• Risk priorities and compliance constraints
• Test accounts/roles and access setup
• Scope boundaries and safety rules for testing

Phase 2: Baseline Checks & Attack Surface Mapping

We run automated scans and configuration checks to map the attack surface quickly. This helps identify common issues early and provides a baseline for deeper validation. Automated results are triaged to reduce noise and focus effort where it matters.

• Automated vulnerability scanning and initial triage
• Endpoint and surface mapping for web and APIs
• Configuration review checkpoints
• Quick wins: high-impact issues that can be fixed immediately

Phase 3: Expert Validation & Exploitability

Automated tools are useful, but they cannot fully validate business impact. We perform manual testing to confirm exploitability and identify real attack chains. This step improves accuracy and helps your teams focus on what actually reduces risk.

• Manual verification of high/critical findings
• Authorization testing with realistic role scenarios
• Business logic abuse and workflow bypass analysis
• Evidence collection aligned with your policies

Phase 4: Reporting, Remediation & Re-Testing

Findings are delivered in a developer-friendly format: clear reproduction steps, impacted endpoints or modules, severity rationale, and recommended fixes. We support remediation through guidance and pairing sessions, then re-test fixes to confirm the issue is resolved and stable.

• Prioritized vulnerability backlog with business impact notes
• Remediation guidance and secure coding recommendations
• Verification re-testing and closure evidence
• Recommendations for preventing recurrence

Phase 5: Continuous Security Testing (Optional)

For teams that ship frequently, security cannot be a one-time activity. We help integrate SAST, dependency scanning, and selective DAST into CI/CD, introduce security gates, and implement a sustainable process for triage and remediation. This creates continuous visibility and reduces “big bang” security reviews before release.

• CI/CD security integration and guardrails
• Severity-based gating policies aligned with maturity
• Ongoing vulnerability triage and backlog management
• Periodic manual testing for major changes and high-risk areas

Delivery models include project-based assessments, monthly retainers, or embedded security testing capacity (dedicated or fractional). Governance includes agreed SLAs for triage, transparent reporting, and regular touchpoints to align security work with delivery priorities.

How Security Testing Creates Business Value

Security testing is often seen as “cost” until an incident occurs. In practice, it is a risk reduction investment that protects revenue, customer trust, and operational continuity. Effective security testing helps:

• Reduce breach probability by eliminating exploitable vulnerabilities and misconfigurations.
• Lower incident impact by strengthening authorization, segmentation, and monitoring controls.
• Improve delivery speed by catching issues earlier, when fixes are cheaper and faster.
• Support compliance with repeatable evidence and consistent security validation processes.
• Enable safer innovation when new features and integrations are built with security guardrails.

Most importantly, security testing provides clarity. Instead of vague “security concerns,” leadership receives a prioritized view of risks, and engineering receives a practical plan to fix them.

Common Risks We See in Real Projects

While every system is unique, certain patterns appear across industries. We regularly see issues such as:

• Authorization gaps: users can access data they should not, often through object-level API flaws.
• Misconfigured cloud resources: overly permissive roles, exposed storage, or unprotected endpoints.
• Weak secrets handling: keys in repositories, unrotated credentials, missing vault usage.
• Dependency exposure: critical vulnerabilities in libraries that are reachable from production paths.
• Missing rate limiting: abuse of APIs for scraping, brute force, or resource exhaustion.
• Business logic abuse: manipulation of workflows, discounts, approvals, or payment flows.

Addressing these risks requires both technical fixes and operational guardrails. Our recommendations therefore include improvements to SDLC practices, not just code changes.
