NIST vs ISO vs SOC 2: Which Security Framework Is Right for You?

Why Choosing the Right Framework Matters

If you're running a growing business in tech, SaaS, or the government space, you've probably heard terms like SOC 2, ISO 27001, or NIST 800-171 thrown around in sales calls, vendor checklists, or security questionnaires.

But here’s the thing:

Security isn’t one-size-fits-all.

Choosing the wrong compliance path can waste months of work, blow up your budget, or lead you down a road that doesn’t even align with your actual goals.

Let’s break down the three most common frameworks so you can pick the one that actually makes sense for your business.

What Is NIST 800-171

NIST 800-171 is built for organizations that handle Controlled Unclassified Information (CUI), primarily in federal or government-adjacent spaces.

It focuses on:

• Access controls

• Encryption

• System auditing

• Incident response

• Risk assessments

Why it’s a strong choice

• It’s well-structured, digestible, and budget-friendly

• You don’t need a third-party auditor to implement it

• It’s a great starter framework if you’re early in your security journey

Best for:

• Startups pursuing DoD/federal contracts

• Businesses entering the GovTech space

• Companies prepping for CMMC down the line

What Is ISO 27001?

ISO 27001 is a globally recognized standard for building an Information Security Management System (ISMS).

It’s all about people, processes, and technology working together to protect sensitive data across your entire organization.

Why companies pursue it

• It’s internationally trusted by vendors, clients, and auditors

• It goes deep—touching HR, engineering, vendor risk, and more

• It positions you as a mature, enterprise-ready business

Best for:

• Mid-size SaaS companies expanding internationally

• Tech businesses working with European or global clients

• Mature orgs looking for structured, ongoing infosec programs

What Is SOC 2?

SOC 2 is a U.S.-centric compliance report focused on how your business protects customer data based on Trust Services Criteria like:

• Security

• Availability

• Confidentiality

• Processing integrity

• Privacy

You don’t “pass” SOC 2—it’s an attestation, issued after a third-party CPA firm audits your controls over time (Type I or Type II).

Why it’s so popular

• It accelerates sales cycles

• Buyers often require it during vendor due diligence

• It speaks directly to SaaS and cloud-first businesses

Best for:

• U.S.-based SaaS or fintech companies

• Startups working with enterprise buyers

• Businesses needing client trust at scale

So... Which One Is Right for You?

Company Type	Recommended Framework
GovTech startup or federal contractor	NIST 800-171
U.S. based SaaS or fintech platform	SOC 2
Global B2B tech or enterprise service	ISO 27001
Pre-audit or early-stage startup	Start with a Readiness Assessment or light NIST alignment

Still unsure? That's normal. Many businesses actually end up blending frameworks depending on their roadmap.
