Understanding NIST CSF 2.0 for Your Business

Every business owner knows the stress of protecting what matters most—customer data, employee information, and the technology that keeps everything running. It’s easy to assume IT security is only for big companies, especially if you run a smaller team or lack in-house support. While businesses of all sizes face threats that can disrupt operations, kickstarting your cybersecurity can be challenging.

That’s where guidelines from organizations like the National Institute of Standards and Technology (NIST) come in. The NIST Cybersecurity Framework (CSF) 2.0 is an excellent compass to follow if you’re getting started with IT security strategies and want practical steps to follow. Keep reading to discover how the NIST CSF 2.0 works and why you should implement it in your organization.

What is the NIST CSF 2.0?

At its heart, NIST CSF 2.0 is a framework for realistically thinking about cybersecurity within your business. It helps you identify risks, prioritize actions, and coordinate efforts across teams—but it’s not a quick fix that’s used once. Brian Schlechter, Director of IT at Bit-Wizards, underlines that this misconception is important to recognize before diving into the framework’s components.

“Some may think that the NIST CSF 2.0 is a solution to their cybersecurity, but it’s exactly what its name includes: a framework,” he says. “Instead of giving you the answers to all of your IT security concerns, it helps you learn what you should investigate and assess to understand your current measures, establish attainable goals, and identify how you can execute your improvements over time.”

What are the framework’s three main components?

NIST CSF 2.0 is organized into a few key components: core functions, profiles, and tiers. These elements make the overall framework actionable for your business, regardless of your size or industry, by outlining steps, identifying risks, and defining desired outcomes. When combined, these components help you break down education, planning, and operations into manageable areas.

The framework uses these six core functions at its center:

• Govern—Define and track your cybersecurity strategy, roles, and policies.
• Identify—Assess your current cybersecurity threats.
• Protect—Implement safeguards to prevent or reduce risk.
• Detect—Monitor for potential cyberattacks and suspicious activity.
• Respond—Establish and execute procedures to address detected issues.
• Recover—Restore systems and operations after an incident.

Beyond these functions, NIST also includes organizational profiles that help businesses understand where they are now and where they want to go. Profiles compare your current cybersecurity posture against a target state, helping you develop a roadmap to establish better risk management procedures. NIST offers an organizational profile template to help you thoroughly examine your current security measures and goals.

NIST created four optional CSF tiers to help you assess the thoroughness and resilience of your cybersecurity posture: Partial, Risk Informed, Repeatable, and Adaptive. These tiers can be applied to your organizational profiles and help you move from informal efforts to detailed procedures over time. Generally, Schlechter believes most businesses are in the “partial” tier when first following the framework.

“If you’re just getting started with cybersecurity and using tools like Microsoft 365 that have built-in protections, you’re somewhat aware of the current risks and what you need to do to avoid them,” he says. “You’re a step ahead by using more secure tools, but there’s much more to do outside of this to ensure your business is protected against cyber threats.”

Do I need an IT background to understand NIST CSF 2.0?

While the NIST framework doesn’t give you all the answers, it does provide the questions that help you know what to consider and include in your cybersecurity plans—even if you don’t have a technical background. At a high level, NIST CSF 2.0 encourages you to ask practical, business-driven questions rather than dive into technical settings. Still, Schlechter notes that implementing the framework requires thorough IT expertise.

“As long as you can identify what you need to protect and where it’s located, whether it’s client information in Salesforce or employee details in an HR system, you don’t need to be a tech-minded person to understand your business data,” he says. “After establishing that baseline, you’ll need to work with someone with an IT background to implement NIST, especially if you’re not sure which way your business needs to proceed.”

How do the six NIST CSF 2.0 core functions work?

Understanding how the NIST CSF 2.0 is structured is only the first step—the real value comes from applying it to your day-to-day operations. Each of the six core functions reflects a practical aspect of protecting your organization, from assigning responsibility to planning for disruptions. Below is our breakdown of how each function applies to your business.

1. Govern

Getting started with the NIST framework requires accountability and direction, since cybersecurity standards begin at the top. You need to define who is responsible for IT security and what success looks like for your business. Even if you’ve spread responsibility across roles with good intentions, Schlechter explains that your efforts can quickly become inconsistent or nonexistent without clear ownership and guidelines.

“If cybersecurity is everyone’s responsibility, it’s no one’s responsibility—you need that one employee or partner who can take charge of your efforts and ensure they get done,” he says. “It’s a good idea to have someone double-checking their work, whether it’s you as a business owner or someone higher up in your IT department, but one person needs to lead the charge in implementing and enforcing your overall IT security policies.”

2. Identify

After you establish clarity on leadership and goals, the next step is identifying your risks. You need to take inventory of the systems and data your operations rely on and consider how a compromise would impact your business. Schlechter underlines that cyber risk is shaped by your industry and the type of data you handle, not the size of your team, making it essential to assess threats through that lens.

“Plenty of small business owners think nation-state threat actors aren’t a concern, but it truly depends on what your business does—and while the odds are low overall, they aren’t zero,” he says. “Your risk profile depends on what data your organization handles and where it’s stored, so business size alone doesn’t mean you’re automatically flying under the radar, especially if you manage sensitive information.”

3. Protect

Once you understand what needs protection, the next step is putting safeguards in place to reduce risk. Protect focuses on the day-to-day controls that keep your systems secure, including access management, employee guidelines, and system configurations. While many modern tools include built-in protections, Schlechter stresses that their effectiveness depends on how you configure and use them.

“Security is a sliding scale—making things more secure often adds friction, while easing up on security measures increases vulnerability,” he says. “Fundamental protections are usually built into most commercial tools, but your cybersecurity posture depends on using them properly. For example, using MFA may be inconvenient, but disabling it can expose you to increased threats and other risks.”

4. Detect

No security setup is perfect, which makes early detection essential. Detect focuses on your ability to recognize unusual or suspicious activity before it escalates into a larger problem. While many systems generate alerts for abnormal activity, Schlechter notes that these notifications are only useful if you understand what they indicate and how to respond appropriately—including when no action is required.

“Security alerts through tools like Microsoft 365 are only helpful if you can determine what they mean or whether they need to be remediated,” he says. “Just because you get an alert doesn’t always mean that something bad has happened within your systems, and it’s critical to have the knowledge to recognize a false positive instead of treating them like true threats and shutting everything down.”

5. Respond

Responding isn’t just about reacting to breaches or false alarms—it’s about following a clear, pre-defined playbook to reduce confusion and downtime. You need to outline the steps your team will take to contain an incident and who to notify internally. Schlechter emphasizes that your response plan should also address whether regulators, insurance providers, or other external parties need to be informed.

“Depending on your industry and whether you have a cyber insurance policy, you may have reporting requirements if a cyberattack or data leak occurs,” he says. “These steps and who is responsible for managing them should be clearly defined, as your business still needs to operate as close to normal as possible while responding and keeping relevant groups informed.”

6. Recover

Even with strong protections and response plans, incidents can still disrupt your operations. Recovering focuses on restoring systems and data after an event, including realistic recovery timelines and steps to return to normal operations. Schlechter notes that your recovery plan should reflect what your business can realistically tolerate in terms of downtime durations and repair costs.

“The two main factors are recovery time objective and recovery point objective, both tied directly to cost,” he says. “Restoring operations quickly and losing less data costs more, while accepting some downtime or data loss can reduce expenses. You need to decide what’s feasible for your business, all while considering any industry requirements that may affect your timeline and budget.”

How can I start implementing NIST CSF 2.0 for my business?

There’s a lot that’s recommended in the NIST framework, but you don’t have to implement every part of it at once to start improving your cybersecurity posture. In fact, you can start small and see meaningful risk reduction by focusing on a few foundational controls first. Any actions and decisions that align closely with NIST guidelines can help build momentum as you work toward larger-scale improvements and additions.

To help you get started, Schlechter highlights several NIST tips that are especially valuable to prioritize:

• Review the NIST CSF 2.0 small business quick-start guide
• Create a business continuity and disaster recovery (BCDR) plan
• Enable multifactor authentication (MFA) wherever possible
• Keep your hardware and software updated at all times
• Use antivirus and endpoint detection response tools
• Create and test backups of your data on a regular basis
• Educate your employees on cybersecurity fundamentals
• Set clear guidelines for using your company’s IT resources
• Jumpstart your IT security and resiliency with Bit-Wizards

Understanding NIST CSF 2.0 is one thing—applying it consistently is another. While the framework helps you ask the right questions, applying those insights to documented processes and ongoing assessments takes extensive experience. Schlechter warns that ignoring IT security or treating it as an afterthought poses the greatest threat to your business.

“Without applying NIST CSF 2.0 or even cybersecurity best practices in general, you’re risking everything if client information is breached,” he says. “Getting started takes time, money, and effort, but being proactive always costs less than reacting after a disaster strikes.”
