RiskClipper
Purpose-built GRC automation. Outcome-focused, audit-ready, designed for organisations where every headcount counts.

A single, integrated programme.
Multiple standards. One team.

Most organisations manage their cybersecurity posture in silos — separate teams, separate consultants, separate compliance tracks. The cost is duplication, gaps, and frameworks that don't talk to each other.

Maximus International's 5-step assurance methodology is designed to eliminate that fragmentation. We build integrated programmes where advisory, testing, training, audit, and automation reinforce each other — reducing organisational burden and strengthening defensibility.

Regulatory Familiarity
Familiar with the requirements and expectations of CSA, IMDA, LTA, EMA, CAAS, and MAS across Singapore's regulated and critical sectors.
ICT + OT Breadth
Enterprise IT governance to ICS/SCADA operational environments.
15+ Year Relationships
Our longest-running clients have retained us across decades of maturity.
Multi-Framework Native
ISO/IEC 27001, IEC 62443, SS 712 — and across NIST CSF, SS 714, ISO 22301, ISO/IEC 20000-1, and ISO 42001 for organisations managing overlapping obligations.
Audit-Advisory Synergy
Our auditors inform our advisory. Our advisory improves audit outcomes.
Delivery Transparency
We are clear about what we deliver, how we deliver it, and who does the work.
Design — Step 01

We Build Your Assurance Programme

Single operations. Multiple standards. Whether your environment is enterprise IT or operational technology, we design programmes that hold up under regulatory scrutiny and operational pressure.

Information Security Management System
ISO/IEC 27001 — ISMS design, gap assessment, risk treatment, and programme management for complex regulatory environments.
IT Service Management
ISO/IEC 20000-1 — ITSMS framework development, service catalogue design, and process maturity improvement for regulated service providers.
Business Continuity Management
ISO 22301 BCMS design, BIA, recovery strategy, plan development, and exercise coordination for critical operations.
Data Privacy Programme
PDPA (SG/MY/TH/PH), GDPR, and ISO/IEC 27701-aligned data governance, privacy impact assessments, and DPO advisory for regulated organisations managing cross-border data obligations.
Integrated GRC
Multi-framework GRC architecture for organisations managing overlapping regulatory obligations across ICT and OT.
Compliance Advisory
Sectoral cybersecurity and compliance readiness across CSA, IMDA, LTA, EMA, CAAS, and MAS-regulated environments — including MAS TRM, Cyber Trust Mark, CII obligations, and sector-specific programme design.
OT Security Programme
IEC 62443 — OT cybersecurity programme design for critical infrastructure operators across energy, utilities, and transport sectors.
Submarine Cable Code
Advisory and compliance support for operators subject to submarine cable security codes and international obligations.
ICS/SCADA Assessment
Operational technology asset assessment, architecture review, and risk analysis across ICS and SCADA environments.
OT Incident Response
OT-specific incident response planning, tabletop exercises, and crisis management for operational technology environments.
SISIR Programme Advisory
Advisory support for SISIR regulatory obligations, including documentation, process alignment, and submission preparation.
OT Business Continuity
Operational continuity planning for OT environments — aligned to production criticality, safety obligations, and regulatory requirements.
Retained Advisory — Longest client relationships span 15+ years
Our advisory engagements are structured for continuity. We act as an embedded extension of your team — managing programmes, attending reviews, and advising across audit cycles. We do not deliver reports and leave.
Test — Step 02

Analyse Your Defences Before the Audit

Expert-led security analysis across your full attack surface. Context-aware, remediation-focused, and ready to support regulatory and audit requirements.

AI + Expert Analysis
AI-assisted tooling with senior practitioner oversight — not automated scanning passed off as testing.
Context-Aware
We understand your regulatory context, not just your attack surface.
Remediation-Focused
Findings come with practical, prioritised remediation guidance — not a CVSS dump.
Testify-Ready
Our reports are structured to support regulatory submission, certification, and audit follow-up.
Delivery Model Transparency: Maximus International operates with full disclosure on how technical engagements are staffed. Expert oversight, methodology ownership, and report quality are non-negotiable — regardless of delivery channel.

Audit That Creates Value

We do not perform audits that generate paperwork. We perform audits that strengthen your posture, satisfy your regulators, and prepare your organisation for the next phase of maturity.

Brutal but Practical
We surface what others miss, and we surface it honestly. Nonconformities come with root cause analysis and pragmatic remediation advisory — not just citation of the clause.
Leaps & Bounds with Advisory
Our audit team draws on two decades of advisory experience. You receive an audit that builds capability, not one that measures it in isolation. The two disciplines reinforce each other.
Regulator-Approved Clarity
Our reports are written for regulator review. Clear findings, defensible methodology, reasonable interpretation of complex clauses, and language that holds up under scrutiny.

GRC Automation for the Manpower-Constrained

"We built RiskClipper because nothing in the market met our standards for operational assurance. It was designed by auditors, for organisations that cannot afford to have their GRC programme depend on headcount."
Risk Scoring That Makes Sense
Contextualised risk ratings aligned to your framework and sector — not generic CVSS values disconnected from operational reality.
Keep Policies Current Without the Admin
Policy lifecycle management with review scheduling, version control, and approval workflow — without manual tracking overhead.
Evidence Ready When You Are
Centralised evidence repository mapped to control objectives. Audit season is never a scramble when evidence is continuously maintained.
Track Incidents to Closure
Incident lifecycle management from initial log to post-incident review — with escalation tracking and regulatory notification support.
Know Your Threat Landscape
Threat intelligence integration and contextualised threat mapping against your asset register and control environment.
Onboard and Manage with Confidence
Supplier and personnel governance integrated into your GRC programme — from onboarding to ongoing monitoring.
