Web Application Penetration Testing

Web application penetration testing is a controlled, manual security assessment in which certified ethical hackers simulate real-world attacks against a web application - including its authentication, session management, business logic, APIs, and access controls - to identify exploitable vulnerabilities before malicious attackers do. It goes beyond automated scanning by validating exploitability and chaining low-severity findings into realistic attack scenarios.

Web application penetration testing in Australia typically starts from AUD $2,000 for a single engagement. The price depends on application complexity, number of user roles, API endpoints in scope, authentication flows, and whether testing is black-box or grey-box. Penva Security provides a fixed-price quote within 24 hours after a free scoping call, with no surprise add-ons.

Most web application penetration tests take 5 to 10 business days of active testing, plus 1 to 2 days for reporting. A small marketing site may be tested in 3 to 5 days; a complex SaaS platform with multiple user roles, APIs, and SSO can take 2 to 3 weeks. Penva delivers findings progressively in a shared tracking sheet so your developers can begin fixing issues during the engagement, not after.

Yes. ISO/IEC 27001:2022 controls A.8.8, A.8.29, and A.5.23 expect technical vulnerability assessments and security testing of applications. SOC 2 Trust Services Criterion CC7.1 requires identification of vulnerabilities, with penetration testing as the standard evidence. PCI DSS Requirement 11.4 mandates application penetration testing at least annually and after any significant change. APRA CPS 234 expects regular testing of information security controls. Penva delivers reports formatted to satisfy all four frameworks.

A vulnerability scan is automated and identifies known issues by signature matching - it produces a long list of potential issues with many false positives. A penetration test is manual, performed by a certified human tester who validates exploitability, chains vulnerabilities together, abuses business logic, and produces a short list of confirmed, prioritised, exploitable findings. Australian compliance frameworks distinguish between the two - scans alone do not satisfy ISO 27001, SOC 2, PCI DSS, or APRA expectations for penetration testing.

No. Penva delivers 100% human-led, manual penetration testing. We use automated scanners only to support reconnaissance and confirm coverage - every finding is manually validated and exploited by a CREST-certified tester. AI-only and scanner-driven services miss business logic flaws, broken access control, IDOR chains, race conditions, and authorisation bypasses, which represent the majority of high-impact vulnerabilities discovered in real engagements.

Penva follows the OWASP Web Security Testing Guide (WSTG v4.2), OWASP Top 10 (2021), OWASP API Security Top 10 (2023), NIST SP 800-115, and the Penetration Testing Execution Standard (PTES). Our process has six phases: scoping, reconnaissance, threat modelling, vulnerability discovery, exploitation, and reporting - followed by a free remediation retest.

Penva tests staging or pre-production environments by default to eliminate any risk to production traffic, customer data, or uptime. Where testing must be performed against production, we coordinate testing windows, throttle automated requests, and exclude destructive payloads. We have never caused an outage in any client engagement.

Yes. Every Penva fixed-price web application penetration test includes one free retest within 60 days of the original engagement. After remediation, we re-validate each finding and issue an updated report confirming closure - required evidence for ISO 27001, SOC 2, and PCI DSS auditors.

Yes. Penva's penetration testers hold CREST Registered Penetration Tester (CRT) and CREST Practitioner Security Analyst (CPSA) certifications, recognised by CREST Australia New Zealand. They additionally hold Offensive Security Certified Professional (OSCP) and HTB Certified Penetration Testing Specialist (HTB CPTS). CREST is the industry-standard certification body referenced by Australian government, financial services, and enterprise procurement teams.

At minimum, annually - the baseline expected by ISO 27001, SOC 2, and most enterprise procurement processes. PCI DSS requires testing after any significant application change. High-velocity SaaS teams releasing weekly should pentest after major feature releases (new authentication flows, payment integrations, role/permission changes) or quarterly. Penva offers Pay-As-You-Go testing from AUD $500/week for teams that need continuous coverage.

Penva identifies critical or high-severity vulnerabilities in approximately 70% of web applications tested. The most common findings are broken access control (especially IDOR and privilege escalation), authentication weaknesses, SQL injection in older code paths, cross-site scripting in user-generated content, server-side request forgery (SSRF), insecure direct object references, JWT misconfigurations, and business logic flaws in checkout, refund, or approval workflows.

Penva serves SaaS platforms, FinTech and payments providers, healthcare and EdTech organisations, e-commerce retailers, professional services, and government supply-chain vendors across Australia, with active clients in Melbourne, Sydney, Brisbane, Perth, Adelaide, and Canberra.

Yes. Penva signs a mutual NDA before any technical or commercial information is exchanged. We can also work to your standard MSA, supplier agreement, or IRAP / data-handling requirements.
