Expert advisory across the full spectrum of cyber security architecture.

Enterprise Security Strategy & Roadmap

Help organisations understand their current security position, define their target state and establish a practical multi-year cyber security roadmap aligned to business risk and priorities.

Effective security strategy starts with an honest assessment of where you are today. Zysla works with your leadership team to evaluate your current security posture, identify gaps against your risk appetite and business objectives, and define a target-state architecture that is realistic and achievable. The output is a prioritised, multi-year roadmap that your board and executive team can understand and act on.

Security Architecture Review & Assurance

Independent security architecture reviews for business-critical technology initiatives.

When your organisation is making significant technology investments, independent security architecture review provides assurance that security has been considered at the design stage — not retrofitted after deployment. Zysla provides objective, expert review of solution architectures, cloud platforms, SaaS integrations and technology programmes, identifying risks and recommending practical treatments.

Security Architecture as a Service

Senior security architecture expertise on demand — without the overhead of building an internal function.

Many organisations need senior security architecture capability but cannot justify a full-time internal hire. Zysla provides ongoing access to senior security architecture expertise on a retained or flexible basis — supporting your project portfolio, architecture review board, and technology decision-making without the cost and complexity of a permanent function.

Cyber Resilience & Regulatory Readiness — APRA CPS 234 & CPS 230

Helping APRA-regulated and high-trust organisations strengthen cyber resilience, satisfy CPS 234 information security obligations, and meet CPS 230 operational resilience requirements.

APRA CPS 234 and CPS 230 impose specific, enforceable obligations on regulated entities — covering information security capability, third-party risk, incident notification, and the resilience of critical operations. Zysla helps organisations move beyond surface-level compliance to build security and resilience programmes that satisfy APRA's expectations and genuinely reduce operational risk. Engagements begin with a structured gap assessment against CPS 234 and CPS 230 obligations, followed by a prioritised remediation roadmap and practical implementation advisory. Where organisations also face Essential Eight or ISO 27001 obligations, Zysla aligns the programme to address multiple frameworks without duplicating effort.

Identity, PAM & Zero Trust

Identity-centric security architectures covering employees, administrators, third parties, devices and workloads.

Identity is the new perimeter. Zysla designs and reviews identity-centric security architectures that address the full scope of your access challenge — from employee and administrator access through to third-party connections, device trust and workload identity. We help organisations move towards Zero Trust principles in a practical, phased way that aligns with their existing investments.

AI Security & Governance

Helping organisations securely introduce artificial intelligence while managing cyber, privacy, data and technology risks.

Artificial intelligence introduces new security and governance challenges that traditional frameworks do not fully address. Zysla helps organisations assess the security implications of AI adoption — from evaluating third-party AI tools and platforms to designing secure AI architectures and establishing governance frameworks that manage risk without stifling innovation.

Virtual CISO (vCISO)

Experienced, senior security leadership delivered on a flexible, part-time basis — providing the strategic direction, governance oversight and executive presence of a CISO without the cost of a full-time hire.

A Virtual CISO from Zysla gives your organisation access to a seasoned security executive who understands both the technical and business dimensions of cyber risk. Whether you are a mid-market organisation without an internal security function, a regulated entity requiring independent security leadership, or a business navigating a period of rapid change, our vCISO service provides the strategic oversight, board-level communication and programme direction your security posture demands — on terms that suit your organisation.

Fractional Security Leadership

Senior cyber security leadership and advisory capability for organisations that require strategic expertise without a permanent executive security function.

Not every organisation needs or can justify a full-time CISO or security executive. Zysla provides senior security leadership on a fractional basis — attending board and risk committee meetings, directing security programmes, advising on technology and vendor decisions, and providing the strategic security voice your organisation needs at the level it needs it.

Third-Party & Cloud Security Assessment

Independent assessment of cloud platforms, SaaS solutions, technology vendors and strategic partners.

Your security posture is only as strong as your weakest third-party relationship. Zysla provides independent, expert assessment of cloud platforms, SaaS solutions, technology vendors and strategic partners — evaluating architecture risk, data security, identity and access controls, integration security and operational resilience to give your organisation confidence in its supply chain.
