Hire Application Security Testing Expert
End-to-End Application Security Testing Services
As the cybersecurity threat landscape for web and mobile applications evolves daily, generic security tools leave critical gaps that automated systems cannot completely solve. To close these vulnerabilities, organizations must hire specialized application security testing engineers who combine deep manual analysis with advanced automated tools to ensure a resilient defense.
Application Security Consulting
Leverage our AppSec consulting focused on architecting secure SDLC. Our AppSec consultants assess your existing architecture, identify the most critical testing priorities, and design a phased application security testing roadmap. We use Snyk for dependency analysis, Burp Suite Professional for deep-dive API logic assessment, and Aqua Security for hardening containerized environments and Kubernetes orchestrations. Our experts also conduct a rigorous gap analysis to help you mitigate risks such as broken object-level authorization (BOLA) and mass assignment. You get a clear plan backed by OWASP and NIST frameworks.
End-to-End Application Security Testing
Hire mobile application security testing experts to strengthen your application security posture across iOS and Android environments. Our app security testing experts use MobSF (Mobile Security Framework) for automated static and dynamic analysis, Frida for runtime manipulation, and Magisk or Corellium for testing in rooted/jailbroken environments. We perform thorough traffic interception and binary analysis, isolate critical mobile-centric risks such as Insecure Data Storage, Improper Communication Link Security (SSL Pinning bypass), and Insecure Task Affinity.
Web Application Security Testing
Secure your web applications with our web app security testing engineers who evaluate front-end inputs, server-side logic, authentication flows, session management, and data storage. We use Checkmarx for static analysis, Acunetix for vulnerability scanning, and Postman for REST/SOAP API probing. Our web security testers combine automated scans and manual reviews to verify resilience against the OWASP Top 10, including injection flaws and broken authentication.
Interactive Application Security Testing (IAST)
Accelerate your development velocity with our interactive application security testing services that identify deep-seated runtime vulnerabilities without stalling your CI/CD pipeline. Our experts utilize a cutting-edge IAST stack featuring Checkmarx ONE, Contrast Security, and Synopsys Seeker to monitor code execution, data flow, and backend interactions during active functional testing. By correlating runtime behavior with source code, we pinpoint complex flaws such as Insecure Deserialization, Cryptographic Weaknesses, and Sensitive Data Leakage that traditional scanners often miss.
API and Microservices Security Testing
Identify API vulnerabilities across REST APIs, GraphQL endpoints, service-to-service communication layers, authentication controls, and containerized workloads. Our security testing experts test exposed and internal APIs for excessive data exposure, schema abuse, injection flaws, and rate-limiting gaps, and validate east-west traffic controls and inter-service trust boundaries in microservice environments. We use advanced tools and frameworks such as GraphQL Voyager and API gateways, aligned with OWASP API Security Top 10, Zero Trust principles, and threat modeling practices.
Web Application Security Penetration Testing
Expose exploitable weaknesses in your browser-based systems with our web application security penetration testing services. Our web security expert simulates adversarial behavior across the full web stack by testing authentication flows, access control logic, input validation, client-side scripts, and third-party integrations. We use advanced tools and frameworks to mitigate risks such as cross-site scripting, SQL injection, CSRF, broken authentication, session fixation, misconfigurations, and logic flaws that automated scans alone often fail to confirm.
Application Security Penetration Testing
Strengthen your overall application attack resistance with our application security penetration testing services. Our application penetration testing experts deploy an offensive stack, including Metasploit for exploit verification, Kali Linux for specialized probing, and Wireshark for deep packet analysis. We conduct rigorous reconnaissance and privilege-escalation simulations to identify vulnerabilities that could lead to unauthorized data access. Our testers deliver a definitive security benchmark, providing the transparency and documented proof of security required to meet compliance mandates and maintain a competitive edge.

Hire Application Security Testing Experts to Secure Every Platform
Our application security testing services are designed to cover every environment your business relies on, ensuring no part of your digital footprint is exposed to threats.
Web Applications
- Validate authentication, session handling, and RBAC via manual abuse-case testing and targeted penetration probing.
- Assess SQLi, XSS, and CSRF vulnerabilities using automated scanners with manual payload execution.
- Review SPAs by inspecting client-side scripts, security headers, and backend responses.
Mobile Applications (iOS and Android)
- Test insecure local storage, hardcoded secrets, and exposed API keys through static analysis of APKs, IPAs, and app binaries.
- Assess authentication flows, token handling, and certificate pinning through dynamic runtime testing and traffic interception.
- Review native and hybrid app behavior by inspecting logs, local device storage, and backend-connected request flows.
Cloud-Native Applications
- Validate Kubernetes workloads and container images through manifest reviews and workload-level security audits.
- Analyze inter-service communication and "east-west" traffic to assess the handling of secrets and trust boundaries.
- Scan AWS, Azure, and GCP environments for misconfigured IAM roles, ingress rules, and exposed resources.
APIs and Third-Party Integrations
- Probe REST, GraphQL, and SOAP APIs with crafted requests to uncover schema abuse and injection flaws.
- Audit OAuth 2.0, JWT, and BOLA risks via token manipulation and privilege-escalation testing.
- Review third-party data exchange and over-permissioning to prevent supply chain vulnerabilities across connected systems.
Legacy Enterprise Applications
- Test monolithic and SOA architectures by validating aging authentication protocols and insecure dependency exposures.
- Analyze middleware connectors through backend workflow reviews and privilege mapping.
- Review regulated environments by mapping findings against exploitability, business impact, and global compliance standards.

Frequently Asked Questions
Hire Application Security Testing Expert: FAQs
The cost of hiring our application security experts is tailored to your specific ecosystem, depending on the complexity of your tech stack and the depth of testing required. We evaluate your risk profile and compliance needs to deliver a scalable engagement model that delivers a high security-to-cost ROI for your mission-critical software assets. Contact us for a tailored estimate.
We offer three models: a dedicated full-time model (one or more application security experts working exclusively on your account), a project-based model (fixed scope penetration testing or audit engagements), and a retainer model (ongoing application security services with agreed monthly hours and deliverables). All engagement models include pre-vetted security experts, NDA protection, and a dedicated project manager.
Our application security testing services cover web applications, mobile applications (iOS and Android), APIs and microservices, cloud-native and serverless architectures, enterprise applications (ERP, CRM), and legacy systems.
Yes. Our experts work across the full spectrum: SAST (static analysis with SonarQube and Checkmarx), DAST (dynamic analysis with Burp Suite and OWASP ZAP), and interactive application security testing (IAST with Contrast Security and Seeker). For most clients, a combined approach delivers the broadest vulnerability coverage and the fewest false positives.
We offer a no-questions replacement guarantee. If you feel the assigned expert is not meeting expectations within the first two weeks, notify your account manager and we will match you with an alternative at no additional cost and no delay to your project timeline.
Our application security testing teams are structured to overlap with US, UK, EU, and Australian business hours. For full-time dedicated experts, we align their working hours to your core hours. For project-based engagements, you receive an account manager in your time zone and a daily written update so there is never a communication gap.
