Global application security market by 2030 — 18.2% CAGR
Monthly U.S. searches for 'application security' — strong demand
Average CPC for 'application security testing' — high commercial intent
APIs are now the #1 attack vector — 4,400 monthly searches for 'API security'
Industry research consistently shows that vulnerabilities caught early in development cost a fraction of what they cost once an application is live — and a breach caused by an unfixed flaw costs millions. Application security testing finds the flaws that automated scanners miss and that attackers actively hunt for: business logic flaws, broken authentication, injection, and insecure API endpoints.
More expensive to remediate a vulnerability in production than during development — IBM Systems Sciences Institute. Shift security left and save.
Expert-led testing of your web applications against the OWASP Top 10 and beyond — injection, broken authentication, XSS, CSRF, business logic flaws, and access control issues. We test the way a real attacker would, finding the vulnerabilities automated scanners miss.
APIs are the #1 emerging attack vector. We test your REST, GraphQL, and SOAP APIs against the OWASP API Security Top 10 — broken object-level authorization, excessive data exposure, broken authentication, and rate-limiting failures.
Security testing for your iOS and Android applications — covering insecure data storage, weak cryptography, insecure communication, and reverse engineering risk. We assess against the OWASP Mobile Top 10 and MASVS standard.
Expert manual and tool-assisted review of your source code to identify vulnerabilities at the source — before they ever reach production. We combine SAST tooling with human expertise to catch flaws automated tools alone cannot find.
Embed security throughout your software development lifecycle. We help integrate SAST, DAST, and dependency scanning into your CI/CD pipeline so vulnerabilities are caught automatically — shifting security left and reducing remediation cost.
Proactive identification of design-level security flaws before a single line of code is written. We model threats against your application architecture, data flows, and trust boundaries to design security in from the start.
Automated scanners are fast and cheap — but they miss the vulnerabilities that cause real breaches. Expert-led application security testing finds what scanners cannot.
Every Propelex application security engagement follows a structured methodology aligned with OWASP testing standards, OWASP ASVS, and PTES — combining automated tooling with deep manual expertise for complete coverage.

Questions from development leads, security teams, and executives securing their applications.
Application security testing is the process of finding and fixing vulnerabilities in software applications — web apps, APIs, and mobile apps. It combines automated tools (SAST, DAST, dependency scanning) with expert manual penetration testing to identify flaws like injection, broken authentication, broken access control, and business logic vulnerabilities. Unlike a network penetration test, application security testing focuses specifically on the application layer, where roughly 70% of modern attacks now occur.
SAST (Static Application Security Testing) analyzes source code without running it, catching flaws early in development. DAST (Dynamic Application Security Testing) tests the running application from the outside, like an attacker would. Manual penetration testing uses human expertise to find business logic flaws, chained exploits, and access control issues that neither SAST nor DAST can detect. Propelex combines all three for complete coverage — automated tools for breadth, expert testers for depth.
Yes. APIs are now the fastest-growing attack vector, and we test REST, GraphQL, SOAP, and gRPC APIs against the OWASP API Security Top 10 — covering broken object-level authorization (BOLA), excessive data exposure, and broken authentication. For mobile, we test native iOS and Android apps as well as cross-platform frameworks against the OWASP Mobile Top 10 and MASVS standard, covering both the mobile client and its backend services.
Propelex application security engagements typically range from $10,000 to $35,000 depending on application complexity, the number of applications and APIs in scope, and whether mobile testing is included. A focused single web app test sits at the lower end; a comprehensive engagement covering multiple apps, APIs, and mobile clients at the higher end. We provide a firm quote after a free scoping call — and a remediation retest is always included.
No. Propelex application security testing is carefully scoped and controlled to avoid disruption. Where possible, we test in a staging or pre-production environment that mirrors production. When production testing is required, we coordinate timing, use non-destructive techniques, and maintain constant communication with your team. We have conducted hundreds of application tests without causing outages — safety is built into our methodology.
Application security testing supports HIPAA, HITRUST CSF, SOC 2 Type II (CC7/CC8), NIST 800-53 (SA/SI controls), NIST CSF 2.0, ISO 27001 (Annex A.14 secure development), CMMC 2.0, and GDPR/CCPA security-by-design requirements. Propelex reports are structured to serve directly as the testing evidence your auditors require — including findings, remediation, and retest confirmation.
