Building an Information Security Program from Scratch

That question has only become more complex. Today, building an InfoSec program is not just about choosing a framework and implementing controls. It now involves navigating expanding regulatory requirements, managing third-party and supply chain risk, and accounting for the rapid adoption of AI systems that introduce new attack surfaces and governance challenges.

The process can feel like a dark art, made more confusing by overlapping frameworks, increasing customer expectations, and a persistent shortage of security talent. Let’s break down the three stages of building an InfoSec program in practical terms, so you can move forward with clarity and confidence.

Three Phases of Building an InfoSec Program

To simplify, building an InfoSec program can still be broken into three main phases:

• Phase 1: Define your plan
• Phase 2: Implement security controls
• Phase 3: Prove compliance

Phase 1: Define Your InfoSec Plan

Many organizations still rush past this step, but it remains the most important. A well-defined plan reduces rework, accelerates audits, and prepares you for customer due diligence. Today, it also ensures your program accounts for AI usage, data flows across ecosystems, and regulatory expectations that are evolving quickly.

This phase includes three key steps:

• Step 1: Define your objective
  Are you pursuing a certification such as SOC 2 or ISO 27001? Or aligning to frameworks like NIST CSF? Increasingly, organizations also need to consider regulations tied to data protection, AI usage, and cross-border data transfers. Your objective will determine the policies, controls, and evidence you need to maintain.
  
  
• Step 2: Conduct a risk assessment
  Once your goal is defined, assess the risks your systems, data, and workflows introduce. This now extends beyond traditional infrastructure. Consider how data moves across cloud environments, third parties, and AI systems. What happens if sensitive data is exposed, misused, or processed in unintended ways? What is the likelihood, given your architecture and dependencies? Clear answers here directly improve trust with customers, auditors, and internal stakeholders.
  
  
• Step 3: Document policies and controls
  Your program is built on policies and controls. Policies define expectations at a high level, while controls operationalize them. For example, a policy may require strong access management, while a control enforces MFA across all systems. Increasingly, controls must also account for continuous monitoring, data usage governance, and automated enforcement, not just static requirements.

Expected Time Spent:
This depends on whether you build from scratch or use prebuilt, mapped frameworks. Leveraging automated systems with standardized policies and controls significantly reduces effort and improves consistency across frameworks.

Phase 2: Implement Information Security Controls

With your plan in place, this phase focuses on execution.

Most frameworks include dozens, if not hundreds, of controls. These must be assigned, implemented, and tracked across teams. This is where programs often slow down, especially when controls span IT, engineering, data, and business teams.

What has changed is the need for controls to operate continuously. It is no longer enough to configure a setting once and document it. Controls now need to adapt to changing environments, new integrations, and evolving threats, including those introduced by AI-driven workflows and automated systems.

To accelerate this phase, organizations are moving beyond spreadsheets and manual tracking. Automated workflows can assign ownership, track progress, and trigger alerts when controls drift out of compliance. This is especially important as environments become more dynamic and distributed.

Expected Time Spent:
This remains the most time-intensive phase. Depending on your size and maturity, implementing controls for frameworks like SOC 2 or ISO 27001 can take several months. Mature organizations with strong security foundations and automation can move faster.

Phase 3: Prove Compliance

The final phase is validation.

Once controls are implemented, you need to demonstrate that they are operating effectively. This may involve responding to customer security questionnaires, internal reviews, or third-party audits such as SOC 2 or ISO 27001.

Auditors will request evidence to validate your controls. This can include:

• Policy documentation
• System configuration screenshots
• Access and activity logs
• Records of completed processes or reviews

What has evolved is the expectation of continuous evidence. Static, point-in-time documentation is no longer sufficient in many cases. Customers and regulators increasingly expect proof that controls are consistently enforced over time.

If your controls are well implemented and monitored, evidence collection becomes far less burdensome. Instead of scrambling to gather artifacts, your program should generate audit-ready evidence as a byproduct of operations.

Expected Time Spent:
Time in this phase often depends on how prepared you are. Delays typically come from gaps in control implementation or fragmented evidence collection. With centralized systems that automate evidence gathering and collaboration with auditors, this phase can be completed in a few months or less.

Moving from Point-in-Time Security to Continuous Governance

Building an InfoSec program is no longer a one-time project. It is an ongoing operational capability.

As AI adoption accelerates, regulations expand, and environments become more interconnected, the most effective programs shift from periodic compliance to continuous governance. Controls are not just implemented, they are monitored. Evidence is not collected manually, it is generated automatically. Risk is not assessed annually, it is evaluated in real time.

For Heads of InfoSec, the goal is no longer just to become compliant. It is to build a program that can adapt, scale, and provide confidence across the business as technology evolves.

That shift is what turns InfoSec from a bottleneck into a business enabler.
