Clear priorities.
Credible assurance.

Discuss a consulting engagementSecurity strategy & fractional CISO
Security roadmaps, risk management, policies, control ownership and board reporting. Turn a long list of issues into decisions, responsibilities and delivery priorities.
ISO 27001 & SOC 2 programme leadership
Lead and support your ISO 27001 and SOC 2 programmes from beginning to end: initial scoping, gap assessment, control implementation, evidence collection, remediation and external audit coordination. Help your team maintain the programme beyond the first audit. Certification and attestation are performed by independent bodies and auditors.
AI governance & third-party assurance
Help implement AI securely in your product or SaaS platform—from architecture and data handling to permissions, integrations and operational controls. Review AI adoption, supplier dependencies and security responsibilities, with support for vendor due diligence, IT audit and evidence-based assurance decisions.
Incident readiness & business resilience
Incident response planning, ransomware readiness, backup strategy, continuity and recovery exercises. Prepare the organisation to respond when a critical service is disrupted.
Secure the platform.
Especially when AI is involved.
Before adding features or accelerating development, understand where your SaaS platform is exposed. Ongyo reviews the architecture, cloud environment and delivery process, then helps you address what matters.
AI-enabled SaaS security
Review how AI features handle data, permissions and external services. Assess prompt injection, sensitive-data exposure and excessive agent access where they apply to your platform.
AI-assisted code & delivery
Apply the same security standards to AI-generated and human-written code. Review dependencies, authentication, business logic and delivery pipelines before changes reach production.
A practical outcome: a prioritised view of risks, recommended controls and a remediation plan your team can use.
Discuss your platformSecurity first.
From judgement
to delivery.
Start with the business risk. Secure the platform. Bring development into the engagement when it serves the right outcome.
Each phase can be a focused engagement.
You don’t need to commission a build to work with Ongyo.
