App Security Perth

Nano Solutions provides application security services in Perth including secure code review, vulnerability assessment and penetration testing (VAPT), and compliance consulting aligned with OWASP, ISO 27001, and the Australian Privacy Principles. Established 2013, WA Government CUAICTS2021 panel supplier (Contractor #225). We secure web, mobile, and API applications across financial services, government, healthcare, and resources sectors.

Comprehensive App Security Services in Perth, WA

Application security cannot be an afterthought. The Australian Cyber Security Centre's Annual Cyber Threat Report recorded a cybercrime report every six minutes in FY2023–24, and the average cost of a data breach in Australia continues to climb year on year. For most Australian businesses, the application layer — the public-facing web apps, mobile apps, and APIs that customers and staff use every day — is the single largest attack surface. Nano Solutions Pty Ltd offers comprehensive App Security Services designed to harden your applications during development, validate them before launch, and protect them in production.

We work across the full Software Development Lifecycle (SDLC). Whether you have an in-flight project that needs a secure-by-design review, a legacy application that has never been formally tested, or a SaaS product approaching a SOC 2 audit, our team aligns testing depth and remediation effort to your business risk profile.

Key Features of Our App Security Solutions

• Secure Development Lifecycle (SDL): We integrate security into every stage of application development — from threat modelling at the design phase, through secure-coding standards during build, automated SAST/DAST in CI/CD, and post-deployment monitoring.
• Vulnerability Assessment and Penetration Testing (VAPT): Black-box, grey-box, and white-box testing of web applications, mobile applications, and APIs against the OWASP Top 10, OWASP API Security Top 10, and OWASP Mobile Top 10. Reports include CVSS-scored findings, evidence, and remediation guidance.
• Secure Code Review: Manual code review by experienced engineers, augmented with SAST tools (SonarQube, Semgrep, Snyk Code) to catch vulnerabilities early — when fixes cost a fraction of post-deployment patches.
• Compliance and Best Practices: We help you meet OWASP ASVS, ISO 27001, the Essential Eight Maturity Model, the Australian Privacy Principles (APPs), PCI DSS, and SOC 2 — translating regulatory text into concrete engineering controls.
• Threat Modelling Workshops: Collaborative STRIDE / PASTA workshops with your engineering team to identify abuse cases, trust boundaries, and prioritised mitigations before code is written.
• Incident Response Readiness: Tabletop exercises, runbook development, and forensics readiness assessments so your team is rehearsed, not improvising, when a real incident lands.

Our Process

Every engagement follows a four-phase methodology refined across a decade of Australian client work:

1. Scope & Threat Model (1–2 weeks): We map your application's attack surface, identify trust boundaries, and agree the rules of engagement, in-scope endpoints, and acceptance criteria.
2. Test & Review: Manual penetration testing combined with automated SAST/DAST. For code reviews we focus on authentication, authorisation, input validation, output encoding, cryptography, secrets management, and business-logic flaws that scanners miss.
3. Report & Remediate: Findings are delivered with CVSS v3.1 scores, exploit evidence, business impact, and step-by-step remediation guidance. We work alongside your developers to fix critical issues — not just hand over a PDF.
4. Verify & Sign-Off: Once remediations land, we re-test to confirm fixes are effective and no regressions have been introduced. You get a clean report suitable for board, auditor, or customer evidence requests.

Compliance Frameworks We Support

• OWASP ASVS & OWASP Top 10: Application Security Verification Standard Levels 1, 2, and 3 — the de-facto baseline for application security testing depth.
• Australian Privacy Principles (APPs): Privacy Act 1988 obligations for personal information handling, including the new mandatory data-breach notification regime.
• Essential Eight Maturity Model: ACSC's eight mitigation strategies — application control, patching applications, configuring Office macros, user application hardening, restricting admin privileges, patching operating systems, MFA, and regular backups.
• ISO/IEC 27001: Information Security Management System (ISMS) controls, including A.14 (System Acquisition, Development & Maintenance) and A.12 (Operations Security).
• PCI DSS: Payment Card Industry Data Security Standard for businesses processing, storing, or transmitting cardholder data — including secure coding (Req. 6.5) and vulnerability scanning (Req. 11).
• SOC 2 Type II: Trust Services Criteria audits for SaaS providers — covering security, availability, processing integrity, confidentiality, and privacy.
• Australian Government ISM: Information Security Manual controls for Commonwealth agencies and contractors handling Official: Sensitive and Protected information.

Industries We Secure

• Government & Public Sector: As a WA Government CUAICTS2021 panel supplier (Contractor #225), we work with state agencies and local councils to validate applications against the Australian Government Information Security Manual and Essential Eight maturity targets — without the full tender overhead.
• Financial Services & Fintech: APRA CPS 234 information-security obligations, PCI DSS for cardholder data, and AML/CTF compliance. We secure customer portals, broker platforms, and back-office reconciliation systems.
• Healthcare & Allied Health: My Health Records compliance, APP 11 reasonable-steps obligations, and clinical-system integrations (HL7, FHIR). Patient data demands a higher bar — and we apply it.
• SaaS & Technology: SOC 2 Type II readiness, customer due-diligence support, and continuous penetration testing programmes that satisfy enterprise procurement teams.
• Mining & Resources: Operational technology (OT) gateways, remote-site portals, and field-data ingestion APIs — secured against the threat model of remote access and intermittent connectivity.
• Education & Non-Profit: Student-data protection, fundraising-platform security, and APP-aligned data-handling for membership organisations.

Why Choose Nano Solutions for App Security?

Manual + Automated, Not Automated Alone

Automated scanners catch known patterns. They miss business-logic flaws — broken access control across tenants, race conditions in payment flows, IDORs in admin endpoints. Our manual testing is performed by senior engineers who have written, broken, and rebuilt these systems themselves.

Developer-First Reporting

Reports are written for engineers who have to fix the problem, not just for executives who have to read about it. Every finding includes the exact endpoint, payload, response, and a code-level remediation example. Your dev team can act immediately.

Local Team, Same Timezone

We are based in Fremantle, Perth — face-to-face workshops, same-day responses, no offshore subcontracting. Sensitive code stays under Australian privacy law and Australian-resident engineers throughout the engagement.

Proven Across the SDLC

We do not just test applications — we build them. Our team has shipped production software for Surf Life Saving Australia, City of Fremantle, Procom, and SLSA's BeachSafe platform serving millions of users. We bring builder context to every test.

Typical Investment

Application security engagements scale with the size of the codebase and the depth of testing required:

• Secure Code Review: From $3,500 for a focused review of a single application module to $15,000+ for a full enterprise codebase audit with remediation guidance.
• Vulnerability Assessment & Penetration Testing (VAPT): From $6,000 for a single web or mobile application to $25,000+ for multi-application engagements with re-testing.
• Compliance Consulting: From $4,000 for an OWASP ASVS or Australian Privacy Principles gap assessment to $20,000+ for ISO 27001 or Essential Eight uplift programmes.
• Continuous Application Security Programme: From $2,500/month for monthly automated scans, quarterly manual review, and on-demand engineering support.

Cost drivers include codebase size, application complexity, integration surface area, compliance framework, and whether remediation work is in scope. Every engagement starts with a free scoping call.
