Nexios brings a developer-centric approach to application security — embedding Secure SDLC practices throughout your engineering process, and conducting penetration testing, threat modelling, and code reviews that identify real vulnerabilities before malicious actors do.
Back to all servicesThe cost of a security breach extends far beyond the immediate technical response. Regulatory penalties, reputational damage, and legal liability make application security one of the highest-ROI investments a software-dependent business can make. Nexios brings a developer-centric approach: security controls that integrate naturally into development workflows rather than creating friction that gets bypassed.
We implement Secure Software Development Lifecycle (Secure SDLC) practices across your engineering process, and conduct penetration testing, threat modelling, and code reviews that identify real vulnerabilities before malicious actors do. For Australian organisations operating under APRA CPS 234, the Essential Eight, or ISO 27001 frameworks, we provide the practical, evidence-based controls and documentation required to demonstrate compliance without disrupting delivery velocity.
Systematic threat modelling identifying attack vectors before they reach production
Manual penetration testing of web applications, APIs, and mobile clients
Secure code review: OWASP Top 10, injection vulnerabilities, access control weaknesses
SAST/DAST automation integrated into CI/CD pipelines
Compliance readiness assessments: APRA CPS 234, Essential Eight, ISO 27001, SOC 2
Incident response playbooks and tabletop exercise facilitation
Battle-tested tools chosen for reliability, scalability, and long-term maintainability.
Practical information to help you plan your engagement with confidence.
Everything you need to know — answered directly and honestly.
For most Australian organisations, annual penetration testing is a minimum baseline — and is required by frameworks including APRA CPS 234 and ISO 27001. We recommend testing after any significant architecture change, major feature release, or following a security incident. High-risk applications in financial services or healthcare warrant more frequent testing.
SAST (Static Application Security Testing) analyses your source code without running it — finding vulnerabilities like injection flaws, hardcoded secrets, and insecure configurations at the code level. DAST (Dynamic Application Security Testing) tests the running application from the outside, simulating an attacker. Both are complementary and we integrate both into CI/CD pipelines.
We conduct penetration testing against a dedicated staging environment that mirrors production, not against your live systems. In exceptional circumstances where production testing is required, we schedule it during low-traffic windows and coordinate closely with your operations team to manage any risk.
APRA CPS 234 applies to all APRA-regulated entities: banks, insurers, superannuation funds, and their material service providers. If your organisation handles financial services data or provides technology services to regulated entities, there is a strong likelihood that obligations apply. We conduct a scoped assessment to determine your compliance obligations before any remediation work begins.
Nexios QA engineers design and implement automated testing strategies that make quality a continuous property of your delivery pipeline — not a gate bolted on at the end.
Nexios DevOps engineers design and implement the entire cloud engineering stack: infrastructure provisioning via Terraform and CDK, containerised workload orchestration on Kubernetes, and fully automated CI/CD pipelines with zero-touch production deploys.
Partner with Nexios to design, develop, and scale secure, high-performance digital solutions.
