The GRC cheat code: Why we stopped auditing from scratch and started mapping the gaps

If you ask any Chief Information Security Officer (CISO) or CIO about their upcoming compliance schedule, you will likely be met with a sigh of exhaustion.

As digital transformation accelerates and technologies like artificial intelligence (AI) and operational technology (OT) converge with enterprise IT, the sheer volume of compliance standards we are expected to maintain is reaching a breaking point. Organisations are no longer just asked for ISO 27001. Now, our boards, customers, and government partners expect SOC 2 Type II, the CIS Critical Security Controls, NZISM compliance, and, most recently, ISO 42001 to govern secure AI workloads.

Under the traditional GRC model, each of these audits is treated as an isolated project.

An organisation hires an external consultancy, spends $100,000 to map out ISO 27001, and files the static Word documents in SharePoint. Six months later, they embark on a SOC 2 audit. The consultants return, charge another $90,000, and ask the same engineers the exact same questions about password policies, physical access controls, and incident response procedures.

This is not cybersecurity. It is administrative theatre. It drains technical resources, burns out security teams, and costs New Zealand businesses millions in redundant consulting fees.

At Spectrum Consulting, we manage the mission-critical systems that power core banking, rail networks, and major utilities across Aotearoa. When we set out to formally certify our own operations, we drew a line in the sand. We refused to participate in manual compliance theatre.

We partnered with Spotica, a Kiwi-developed digital GRC platform, and achieved our ISO 27001 certification in just nine and a half months, at roughly a quarter of the cost of traditional methods. But the speed of our initial certification wasn't the most exciting outcome.

The real value lies in what we are doing next: mapping the gaps.

The multi-framework reality

The secret that high-priced GRC consultants rarely advertise is that international compliance frameworks overlap by up to 70 to 80 per cent.

The core elements of information security do not change between standards. Whether you are auditing for ISO 27001, SOC 2, or CIS Controls, you still need to prove you have a robust asset register, restricted access controls, documented change management, and a thoroughly tested incident response plan.

Rather than auditing these requirements from scratch for every single standard, modern enterprise security teams must adopt a unified, digital control lake.

By utilising Spotica's multi-framework engine, we have centralised our core controls. Our validated ISO 27001 compliance serves as our baseline. As we transition straight into securing ISO 42001 for our sovereign AI initiatives and SOC 2 Type II for our sovereign private cloud and secure S3 storage, we do not need to re-verify our entire security posture.

Instead, we use Spotica's gap-analysis capability. The platform automatically maps our existing, audited ISO 27001 controls against the parameters of SOC 2 and ISO 42001.

The result? We only need to focus our engineering effort on the operational gaps between the standards.

If ISO 42001 requires specific data governance rules for training machine learning models that aren't fully covered in Annex A of ISO 27001, we see that delta immediately on our dashboard. We address only that specific gap. We don't waste a single hour re-submitting evidence for our network boundary firewalls or employee background checks.

Building a living security culture

Shifting from a manual, document-centric GRC model to an active, digital ISMS does something even more critical than saving hundreds of thousands of dollars: it transforms corporate culture.

When compliance is driven by spreadsheets, it remains isolated within the IT department. But when you deploy a digital GRC platform, you can enforce direct, distributed ownership of security policies across your Senior Leadership Team (SLT).

At Spectrum, our security policies were logically categorised and assigned directly to the business units that execute them. Our Head of People & Culture actively owns HR onboarding security policies; our CFO owns financial control security. Because they are operational owners within a shared digital ecosystem, security ceases to be an IT-imposed bottleneck and becomes embedded in the organisational DNA.

This structured visibility extends directly to the board of directors. Instead of translating complex technical jargon into static PowerPoint slides, we pull clean, visual compliance dashboards directly from the platform. It provides the board with real-time confidence that our risk mitigation strategies are operating exactly as designed.

The CISO & CFO's call to action

To fellow technology and risk leaders across Aotearoa, we should reject the inefficiency of manual, repetitive compliance. In an era of escalating ransomware threats and tight operational budgets, our engineering hours are too valuable to be wasted on duplicated administrative work.

It is time to automate overhead. Treat your compliance controls as a single, unified, dynamic architecture. Leverage local, sovereign-first digital platforms to run your GRC. Focus your energy strictly on the operational gaps and spend your saved time on what actually matters: defending your enterprise, securing your critical infrastructure, and protecting your data as a taonga.
