Security Frameworks Explained: Choosing Between NIST CSF and CIS

MSPs face mounting pressure to strengthen security postures—both for themselves and their clients. Small and mid-market businesses are increasingly targeted by sophisticated threat actors using accessible, low-cost tools to scan networks and exploit vulnerabilities. As these attacks rise, clients expect more than just tools; they want comprehensive security programs that demonstrate proper protection measures.

This is where cybersecurity frameworks come in. But with multiple options available, how do you determine which framework best suits your MSP and clients?

Understanding NIST CSF and CIS

NIST Cybersecurity Framework (CSF) offers a flexible, risk-driven approach suitable for organizations of any size or industry. It's structured around six core functions:

• Govern
• Identify
• Protect
• Detect
• Respond
• Recover

These functions align with the cybersecurity lifecycle and focus on what you should do rather than how to do it, making it ideal for strategic planning and risk management.

‍CIS Controls, meanwhile, provide a more tactical approach with 18 control groups containing 153 safeguards. CIS is prescriptive and implementation-focused, offering specific guidance on defending against common threats. The framework is structured in three implementation groups (IGs):

• IG1: Essential cyber hygiene for all organizations
• IG2: Enhanced controls for organizations with more resources
• IG3: Advanced controls for organizations with mature cybersecurity programs

Making the Right Choice for Your MSP

Consider these factors when selecting a framework:

Choose NIST CSF if:

• Your clients require risk-based reporting to boards or executives
• You serve mid-market companies (150 to 1,500 employees)
• You offer virtual CISO services
• Your team has security expertise beyond technical implementation
• You maintain regular business reviews focus on security outcomes

Choose CIS if:

• You primarily serve SMBs (under 150 employees)
• You're just starting your security offerings journey
• Your team is technically focused with limited security specialists
• You need a structured, step-by-step implementation approach
• You want clear metrics to demonstrate progress

Many successful MSPs utilize both frameworks—NIST CSF for strategy and client communication, while leveraging CIS for practical implementation guidance.

The Business Impact of Framework Adoption

Beyond security benefits, implementing frameworks delivers business advantages:

• Transparent expectations between you and clients
• Streamlined, consistent service delivery
• Reduced human error and security gaps
• Improved client retention through demonstrated value
• Competitive differentiation in a crowded market

Additionally, frameworks align with numerous regulations and standards. This means a client that initially needs basic security might later discover regulatory requirements—and you'll already have much of the groundwork in place.

Simplifying Framework Implementation

The prospect of implementing comprehensive frameworks can seem daunting, especially for resource-constrained MSPs. That's where Todyl GRC comes in.

As part of our unified security platform, Todyl GRC automatically maps security controls Todyl delivers to frameworks, provides pre-built policies and procedures, and includes SIEM integration for evidence collection—all in one unified solution. This dramatically reduces the overhead of framework adoption while maximizing the business benefits.
