The Three-Dimensional Scoping Approach

When approaching ISO27001, many startups make the mistake of trying to boil the ocean—attempting to secure everything, everywhere, all at once. This leads to overwhelming complexity, extended timelines, and often, burnout before certification.

Smart scoping operates across three dimensions: information assets, organisational boundaries, and control selection. By making strategic decisions in each area, you can create a focused ISMS that delivers maximum security value with minimum overhead.

Dimension 1: Information Asset Scoping

The foundation of efficient scoping starts with a simple but powerful question: What information actually needs protection? Rather than including all company data, identify your crown jewels—the information assets that would cause significant harm if compromised.

For most SaaS startups, this typically includes:

• Customer data stored in your production environment
• Intellectual property associated with your core product
• Critical business information like financial records and sensitive employee data

By focusing on protecting specific information rather than everything, you create natural boundaries for your ISMS. This precision allows you to include only the systems, people, and processes that interact with these key assets—dramatically reducing scope complexity.

Dimension 2: Organisational Boundary Scoping

Contrary to common belief, ISO27001 doesn't require you to include your entire organisation in scope. Many startups achieve certification by scoping in only specific departments, systems, or (physical) locations.

Consider a B2B SaaS company with teams across product development, marketing, finance, and customer success. After identifying that customer data and product IP are their critical information assets, they might scope in:

• The engineering and product teams
• Their cloud infrastructure and code repositories
• Customer success teams with access to production data

Meanwhile, they could legitimately exclude marketing teams and systems that don't process sensitive data, satellite offices without access to critical systems, or vendors that only provide non-essential services.

Dimension 3: Control Selection Scoping

ISO27001's Annex A contains 93 controls, but the standard explicitly states that not all are relevant for every organisation. Startups and SMEs often legitimately exclude several controls after proper risk assessment, for example:

• Remote teams and teams that treat their office like a public space may scope out (most of the) physical controls (A.7.1 - A.7.14).
• Teams that do not write software or have outsourced software development may benefit from scoping out the software development controls (A.8.25 - A.8.29). Control A.8.30 covers outsourced software development. These teams may also choose to keep these controls in scope for their valuable guidance in monitoring their software suppliers, but in this case the actual implementation of these controls should be combined with controls A.5.19 - A.5.23 related to supplier contracting and monitoring.
• Teams that have contracted the underlying service or product that a control applies to may refer these controls to the supplier as well. In this case it's important that the supplier is able and contracted to demonstrate compliance to the control, for instance by providing an ISO27001 statement of their own, and that the team itself implements the supplier contracting and monitoring controls.

This approach doesn't weaken your security posture, but it can reduce your implementation effort from 20 to 60% in ideal scenarios. In fact, we would argue that a proper scoping actually strengthens the ISMS by focusing resources where they matter most.

Small Actions, Big Impact

With your scope clearly defined, you can now focus your implementation efforts where they matter most. The most successful startups we work with take a targeted approach:

They identify the highest-risk areas within their defined scope and implement controls there first. This creates immediate security improvements for critical assets while building momentum for the broader implementation.

For example, if your customer data is your crown jewel, start by strengthening access controls and encryption for that specific data before moving to lower-priority areas. This approach delivers tangible security improvements within weeks rather than months.

The Automation Advantage

Smart scoping and targeted implementation become even more powerful when combined with automation. For each in-scope control, ask: "Can this be automated rather than manually maintained?"

Automation platforms turn your compliance framework into living systems that adapt as your business evolves. Access reviews happen automatically. Policy acknowledgements trigger when needed. Audit trails build themselves. The manual drudgery that makes compliance feel burdensome simply disappears.

When combined with smart scoping, automation can reduce your overall compliance effort by 50-70% compared to traditional approaches. We've seen companies complete ISO27001 implementation in as little as 12 weeks versus the industry average of 6-9 months by pairing intelligent scope decisions with automation tools that eliminate repetitive tasks.

For a startup with limited resources, this shift from reactive to proactive compliance isn't just convenient—it's essential for scaling securely without ballooning your security team headcount.

The Ripple Effect on Growth

The most overlooked benefit of smart scoping is its impact on your growth trajectory. When you achieve compliance more quickly through focused effort, you unlock enterprise sales opportunities months earlier than competitors taking the "boil the ocean" approach.

Enterprise customers care less about the breadth of your security controls and more about the depth of protection for their specific data. A tightly scoped but well-executed ISMS demonstrates security maturity more effectively than a broad but shallow implementation.

Additionally, you'll find development accelerates rather than slows. By concentrating security requirements on truly critical systems, you avoid creating unnecessary friction for teams working on lower-risk areas. This balanced approach maintains your startup agility while providing appropriate protection where it matters.
