Summary
Zero Trust isn’t hard – it’s about focus. Most CISOs struggle because they treat Zero Trust like an all-or-nothing moonshot. In reality, Zero Trust is a strategy applied incrementally to one protect surface at a time, using tools organizations already own.
This guide shows how to cut through scope creep with a 3-week Zero Trust sprint:
- Week 1: Align stakeholders and define the first high-value protect surface.
- Week 2: Map real data flows and build a practical, tool-based plan.
- Week 3: Enforce policy, monitor, and deliver results.
Instead of chasing enterprise-wide perfection, leaders can prove measurable wins in weeks, reduce risk where it matters most, and build sustainable momentum.
Another headline says 88% of CISOs struggle to implement Zero Trust. Fair – if “Zero Trust” means “boil the ocean.” But that isn’t Zero Trust. It’s a scope problem.
Zero Trust is not a product or a moonshot project. It’s a strategy you apply one critical protect surface at a time, with tools you mostly already own, and a cadence the business can follow. That’s not wishful thinking – that’s how the model is defined by NIST and practiced in the field every day.
What Zero Trust is (and isn’t)
- Zero Trust = strategy, not a SKU. NIST describes Zero Trust as a set of principles that shift defenses from perimeter assumptions to continuous verification of users, assets, and resources. That’s inherently modular and iterative.
- Industry guidance is incremental by design. CISA’s Zero Trust Maturity Model lays out staged progress, not “big bang” deployments. If your plan can’t be sequenced, it’s not aligned with the model.
- A practical, five-step blueprint exists. Start by defining protect surfaces (DAAS: data, applications, assets, services), map flows, build the micro-perimeter, write policy, then monitor & maintain. That’s how you turn strategy into operations – stepwise.
Why leaders feel Zero Trust is “hard”
The CSO piece highlights real pain: competing definitions, long ROI horizons, and cross-department friction. All true when teams aim at “enterprise-wide Zero Trust” as a single deliverable. The result is analysis paralysis, budget sprawl (protecting low-value zones like guest networks), and no early wins to finance the journey.
It’s time to flip it: limit scope to the most important protect surface first (e.g., Customer Relationship Management tools or ERP), where business owners see direct risk reduction. That unlocks sponsorship, evidence, and momentum.
The 3-Week Zero Trust Sprint (what we run with exec teams)
Three moves, one outcome: ship policy where it matters – using what you already own.
Our playbook is very straightfoward:
- Week 1: Build readiness, align on Zero Trust, and define the first protect surface and “done.”
- Week 2: Map real flows, use existing controls, and make a concrete actionable plan.
- Week 3: Implement the plan, enforce allow-only policy, and start monitoring/telemetry.
That’s not theory – it’s a protect surface live in production in 21 days.
CISO quick win: Most organizations already own 70 – 90% of the needed controls (identity, network, endpoint, cloud). Focus protection where it counts: close only the gaps that endanger your first protect surface. Everything else can wait. This way you cut cost while proving measurable value instantly.
What “good” looks like (and why it’s not hard)
- Small blast radius. You’re not remediating your whole estate – just the flows that touch one high-value Asset (HVA).
- Fast proof of value. By focusing on a critical business system, you can demonstrate reduced lateral movement, stronger access hygiene, and cleaner audit findings in weeks, not years. NIST explicitly positions ZT to prevent data breaches and limit internal movement – exactly what a tight micro-perimeter delivers.
- Built to iterate. CISA’s maturity model expects staged advancement across pillars. Ship one protect surface; repeat.
The five steps, translated for busy executives
- Define Your High-Value Protect Surface. Pick the one that matters most to revenue, safety, or compliance.
- Map the Transaction Flows. Understand how the protect surface is used – users, apps, services, APIs, devices.
- Build the Micro-Perimeter. Place controls as close as possible to the protect surfice (on-prem or cloud).
- Create the Policy (Kipling Method). Only allow-list, legitimate communication is allowed – everything else is blocked.
- Monitor & Maintain. Feed telemetry to your SOC/MDR; tune policy with real-world data.
These are simple steps your team can take within weeks – not months, or years.
Budget where risk lives (not the guest Wi-Fi)
But what about the budget, you ask? Aim your spend at the crown jewels. Pick one protect surface (CRM/EMR), wire up the real flows, and enforce policy next to the data. Defer low-value zones (such as guest Wi-FI) and generic perimeter upgrades that don’t cut material risk.
When you evaluate zero trust vendors, prefer controls that sit close to the data and snap into your IdP/EDR/NGFW- fewer tools, tighter telemetry, faster wins in zero trust data security.
Who owns what: clear roles, clear outcomes
Keep it small, sponsored, and shippable. Scope to one protect surface, appoint a business unit owner, and define “done” as shipped policy plus 30-day telemetry. Incentives track outcomes: unknown flows → zero, privileged paths → MFA, vendor access → least-privilege and time-boxed.
Show the win, then repeat. That’s how you turn the industry’s “88% struggle” story into momentum.
The bottom line
Zero Trust gets called “hard” when it’s treated like an enterprise-wide replatform. Treat it like what it is – a business-driven strategy executed one protect surface at a time – and it becomes the most doable security program you’ll ever run.

FAQ
Why do 88% of CISOs struggle with Zero Trust?
Because they treat it as an enterprise-wide replatform instead of a stepwise strategy. Success comes from focusing on one protect surface at a time.
What is Zero Trust – and what isn’t it?
It’s not an SKU or single product. NIST defines it as principles of continuous verification. It’s modular, iterative, and based on existing controls.
How can Zero Trust be implemented in just 3 weeks?
By scoping to one high-value system (like CRM or ERP), aligning stakeholders, and using existing tools to enforce allow-only policies. ON2IT’s sprint delivers policy in production within 21 days.
What’s the ROI of a Zero Trust sprint?
Faster risk reduction, measurable policy enforcement, and early wins that build sponsorship – all without heavy new spend, since most orgs already own 70–90% of the needed controls.
How do you budget for Zero Trust?
Spend where the risk lives – on crown jewels like CRM or EMR – before wasting budget on low-value areas like guest Wi-Fi.
Who should own Zero Trust initiatives?
Business unit owners should sponsor each protect surface, with clear “done” criteria: shipped policy plus 30 days of telemetry.
