Andersen applies tested security methodology across changing environments and gives teams repeatable assurance.
Penetration Testing as a Service (PTaaS)
Andersen delivers Penetration Testing as a Service across applications, cloud, and infrastructure. Recurring expert validation finds exploitable weaknesses faster, prioritizes remediation, and keeps security evidence current.
Proven security expertise at scale
Our security engineers have assessed applications, networks, cloud estates, and critical assets for global organizations.
Certified security experts combine human expertise with automation to produce accurate results and clear actions.
Core capabilities of our PTaaS
For teams with changing systems, our continuous testing and pentesting identify vulnerabilities as the attack surface evolves and reduce delayed detection.
The service covers:
- Recurring checks across agreed applications, networks, and cloud assets;
- Change-aware testing for new exposure and security controls;
- Findings prepared for security and development teams.
Andersen uses AI-assisted discovery and automation to expand test coverage and frequency. AppSec engineers validate the results, so organizations assess more assets without relying on unverified alerts.
Automation supports:
- Repeatable discovery and test execution;
- Signal collection across external and internal systems;
- Faster routing of results for analyst review.
Security engineers review automated and manual pentesting findings for product teams, confirm exploitability, and remove noise before remediation work begins.
Validation includes:
- Controlled reproduction of security vulnerabilities;
- Context on access, affected systems, and attack paths;
- AppSec engineer review before report delivery.
Risk-based pentesting assessment helps security teams focus on findings that threaten critical assets, business operations, data, or compliance requirements first.
Priorities reflect:
- Exploitability and exposure;
- Asset importance and business impact;
- Dependencies that affect remediation efforts.
Our security experts provide pentesting remediation guidance that gives development teams a practical route from validated finding to controlled fix.
Teams receive:
- Evidence and reproduction steps for each finding;
- Recommended corrective actions tied to the root cause;
- Clear conditions for verification.
After fixes, Andersen retests affected systems through pentesting to verify closure, measure residual exposure, and keep the security posture aligned with change.
Retesting confirms:
- The reported vulnerability no longer reproduces;
- Related attack paths remain controlled;
- Evidence is ready for internal and external review.
A testing report validated by an AppSec engineer gives stakeholders accurate results, ownership context, and evidence for security decisions.
The report contains:
- Scope, methodology, and test coverage;
- Severity, impact, evidence, and prioritized findings;
- Remediation status and retest conclusions.
Reduce vulnerability exposure with a sustained program built for continuous security validation
Our security certifications
Andersen's certified security specialists apply recognized practices to deliver penetration testing with validated findings and documented evidence that supports compliance requirements.
Benefits of Penetration Testing as a Service
Andersen combines recurring pentesting, human expertise, and prioritized remediation so organizations can reduce risk while security testing scales with the environment.
Continuous visibility into security risks
We repeat pentesting checks as systems change, helping security teams identify vulnerabilities earlier and maintain a current view of external exposure, internal weaknesses, and critical assets. Comparing cycles helps teams distinguish new weaknesses from recurring gaps.
Faster vulnerability remediation
Verizon's 2026 Data Breach Investigations Report puts the median time to fully patch known exploited vulnerabilities at 43 days. Andersen validates pentesting findings and supplies remediation guidance with evidence, allowing development and security teams to route ownership, fix root causes, and verify closure sooner.
Reduced exposure to exploitable vulnerabilities
In Verizon's 2026 Data Breach Investigations Report, vulnerability exploitation started 31% of breaches and overtook stolen credentials as the top entry point. Andersen's pentesting separates exploitable weaknesses from lower-impact noise, so organizations direct remediation efforts toward attack paths most likely to affect business operations.
Scalable security testing without team expansion
Building an in-house penetration testing team takes hiring time and budget. Automation increases pentesting coverage while security engineers retain control of validation, giving growing organizations more assessment capacity without adding a dedicated internal team. Flexible scheduling lets teams handle release peaks without delaying delivery.
Integrate PTaaS into your security workflow
Andersen can connect testing results with existing security and development workflows so findings reach the right owners without creating a separate operating model.
Testimonials
Client reviews show how Andersen teams work within in-house processes, communicate on time, and stay on issues until they are resolved, the habits a recurring testing engagement depends on.
Turn validated security findings into verified remediation progress for critical systems
Security reporting that drives remediation
Andersen turns validated testing evidence into prioritized findings and practical recommendations that security and development teams can act on.
Validated findings
Each pentesting finding includes reproduction evidence, affected assets, access conditions, and impact. An AppSec engineer validates the result so teams can confirm the issue and scope corrective work.
Prioritized recommendations
Risk context, business importance, and attack feasibility shape the recommended order of work. Security teams receive clear remediation guidance instead of an undifferentiated list.
Remediation-ready insights
The testing report explains root cause, corrective action, and verification criteria. After remediation, retesting records closure and any residual exposure for audit-ready assurance.
Test across your evolving digital attack surface
The program can cover the environments that matter most to each organization, giving security leaders a repeatable way to assess new exposure as technology changes.
Web applications
Andersen uses web application and API pentesting on customer-facing and authenticated paths to uncover vulnerabilities that could expose data, accounts, or business functionality.
Mobile applications
Our specialists run mobile pentesting on iOS and Android apps and their connected APIs, checking authentication, data handling, session control, and API access.
Cloud environments
Cloud penetration testing examines exposed services, permissions, configurations, and trust relationships that can expand access across cloud infrastructure.
