In cybersecurity, timing is everything. You can have robust firewalls, elite engineers, and top-tier compliance frameworks, but attackers will find a way in if your security testing trails behind your development cycles.
In 2024, 26% of all breaches involved web application attacks, making them the second most common threat vector. Traditional penetration testing, which is manual, slow, and point-in-time, just can’t keep up with the dynamic pace of web applications today.
Penetration Testing as a Service (PTaaS) platforms embed testing into the software development lifecycle, enabling real-time risk detection, faster remediation cycles, and scalable coverage across complex environments—capabilities that traditional pen testing simply can’t match.
Penetration Testing as a Service (PTaaS) is a delivery model that provides on-demand, scalable, and continuous penetration testing through a cloud-based platform that integrates directly into your SDLC. Instead of relying on static, consultant-led assessments conducted once or twice a year, PTaaS gives security teams ongoing access to testing infrastructure, tooling, and expert resources through a centralized interface.
These platforms allow users to scope tests, trigger assessments across staging or production environments, and receive findings as they’re discovered. Results typically include technical details, exploit paths, business impact, and remediation workflows that plug into existing systems like Jira or ServiceNow. Many also support retesting, SLA tracking, and compliance-ready reporting.
The real value of PTaaS lies in operational efficiency. Teams no longer need to coordinate lengthy scoping calls, wait weeks for final PDFs, or handle security testing as a standalone project. PTaaS embeds directly into engineering workflows, making offensive security faster, repeatable, and easier to manage across multiple applications.
In dynamic DevOps environments, where application code is updated frequently, traditional point-in-time assessments often miss critical vulnerabilities introduced between releases. New generation PTaaS like Terra integrates into CI/CD pipelines to trigger tests automatically with each deployment, ensuring security keeps pace with engineering and enabling earlier detection.
From scoping to report delivery, pen testing delays can stretch for weeks when handled manually. PTaaS platforms eliminate this lag by streaming findings in real time. Security teams can triage, assign, and retest vulnerabilities faster, lowering mean time to resolution (MTTR) and minimizing exposure.
PTaaS platforms scale testing across these assets simultaneously, enabling broader coverage without requiring a proportional increase in headcount. Dashboards consolidate all activity, while automation handles test runs and reporting, allowing companies to operationalize web application security best practices across their entire portfolio.
Leading PTaaS platforms can replicate attacker behavior to uncover flaws tied to how an application is intended to function. These include logic flaws like bypassing purchase workflows, abusing discount logic, or manipulating user permissions. These vulnerabilities are unique to each app and require testing approaches that consider business context.
Many PTaaS platforms offer built-in compliance mapping for SOC 2, ISO 27001, HIPAA, and PCI-DSS standards. They provide audit-ready pen testing reports, test logs, and remediation evidence—all formatted for technical and regulatory stakeholders.
NetSPI delivers its PTaaS through the NetSPI Platform, giving security teams a centralized place to launch tests, monitor findings, and manage remediation across assets.
