Advisory Services
Virtual CISO for Australian Organisations
Senior security leadership on a retained advisory basis. Zysla’s virtual CISO service provides the strategic direction, regulatory expertise, and board-level governance capability of a full-time CISO — structured for organisations that require the function without the full-time headcount.
The service
Strategic security leadership, without the full-time hire
Many Australian organisations — particularly those in APRA-regulated sectors, critical infrastructure, and mid-market enterprise — require the strategic security function of a CISO but cannot justify or sustain a full-time executive appointment. Zysla’s virtual CISO service fills that gap with senior, independent advisory delivered on a structured retainer.
The engagement is designed to function as a genuine security leadership capability — not a compliance checkbox. Zysla works alongside your executive team and board to establish security strategy, manage regulatory obligations, direct security investment, and provide the governance structures that regulators, auditors, and insurers expect to see.
Engagements are calibrated to your organisation’s current maturity, regulatory exposure, and internal capability. Whether you are establishing a security programme from the ground up, preparing for an APRA prudential review, or seeking to strengthen board-level cyber governance, the scope is structured accordingly.

Regulatory advisory
APRA, Essential Eight, and ISO 27001 — advisory grounded in Australian obligations
Zysla’s vCISO engagements are informed by the specific regulatory landscape Australian organisations operate within. Compliance is treated as a floor, not a ceiling — the objective is a security programme that satisfies regulatory obligations and genuinely reduces risk.
APRA CPS 234 & CPS 230
Advisory for APRA-regulated entities on information security capability, third-party risk, incident notification obligations, and operational resilience requirements under CPS 234 and CPS 230. Includes gap assessment, remediation roadmap, and audit preparation.
Essential Eight
Maturity assessment against the ACSC Essential Eight mitigation strategies, prioritised uplift roadmap, and ongoing advisory to progress maturity levels aligned with your organisation’s risk profile and ASD guidance.
ISO 27001
Framework alignment, gap analysis, and programme direction for organisations pursuing ISO 27001 certification or seeking to align their security management system with the standard. Includes policy development and control implementation advisory.
Engagement model
Typical engagement scope
Engagements are structured as retained advisory relationships with a defined monthly cadence. Scope is agreed at the outset and reviewed periodically as your programme matures.
Programme establishment
Current-state assessment, risk register development, security strategy and roadmap, policy framework initiation, and regulatory gap analysis against applicable obligations (APRA, Essential Eight, ISO 27001).
Ongoing advisory
Monthly or fortnightly engagement cadence covering risk posture review, programme milestone tracking, incident response readiness, board reporting preparation, and regulatory advisory as obligations evolve.
Board and executive engagement
Preparation and delivery of board-level cyber risk reporting, executive briefings on emerging threats, and governance documentation that meets APRA and ASX disclosure expectations.
Incident response leadership
On-call advisory during security incidents — providing strategic direction, stakeholder communication guidance, regulatory notification assessment, and post-incident review.
Why Zysla
What distinguishes Zysla’s vCISO from a managed service
Senior practitioner, not a managed service
Zysla’s vCISO engagements are led by a senior security architect with direct enterprise experience — not a team of analysts operating from a playbook. You receive the same calibre of judgement as a full-time CISO, without the overhead.
Regulatory fluency across Australian frameworks
Deep working knowledge of APRA CPS 234, CPS 230, the Essential Eight, ISO 27001, and the Australian Privacy Act. Zysla translates regulatory obligations into practical security programmes that satisfy auditors and protect the business.
Independent and vendor-neutral
No product affiliations, no reseller arrangements. Recommendations are driven entirely by your risk profile and operational context — not by vendor incentives or pre-packaged tooling stacks.
Flexible engagement model
Structured as a retained advisory relationship with a defined monthly cadence. Scope is calibrated to your organisation’s maturity, regulatory exposure, and internal security capability — from foundational programme establishment through to board-level risk governance.
