The NIST Cybersecurity Framework (CSF) is a best security practice framework established by the national institute of standards and technology. It helps guide you in creating a cybersecurity program and tiers to achieve throughout a security programs lifecycle. Most don’t know or leverage the levels of which you can apply the framework to best address your individual risk tolerance or appetite. Below is an image for a visual representation of the tiers of the maturity levels and directly below are more explanation for each tier. This will help guide you on making an informed decision on how to best achieve your organizational risk reduction goals.

In most scenarios I see organizations fall into specific tier levels but it does depend on factors like size, applicable laws and regulations, resources and leadership and board acceptance. It can also depend on current risk assessment and remediation efforts being performed to determine levels of risk within the organization. As a general rule from my experience SMBs usually can achieve between tier 2 and 3, while mid-sized between tier 3 and 4 while larger enterprises and financial organizations within tier 4 and 5. Another rule of thumb is larger organizations usually have more dedicated staff IT and security wise to achieve higher levels. Also keep in mind that some larger organizations especially financial organizations the laws and regulations governing them are much more strict and the impact of not adhering to them could lead to penalties.

Tier 1 – Partial

To achieve Tier 1, organizations typically begin by identifying critical assets (Business impact analysis – BIA process), documenting basic cybersecurity risks (Risk Assessment), and implementing fundamental security controls based on people, process and technology. Risk management activities are generally reactive and informal, with cybersecurity decisions often made on a case-by-case basis. The goal at this stage is to establish awareness of cybersecurity risks and create an initial inventory of systems, data, and processes.

Tier 2 – Risk Informed

To reach Tier 2, leadership should formally recognize cybersecurity risks and begin integrating risk considerations into business decisions. Organizations should develop basic cybersecurity policies, assign security responsibilities, conduct periodic risk assessments, and establish communication channels for sharing risk information. While practices may not yet be fully standardized, management involvement becomes more consistent and proactive.

Tier 3 – Repeatable

Achieving Tier 3 requires documented and standardized cybersecurity processes (Governance, Risk & Compliance – GRC) aspects that are consistently implemented across the organization. Security policies, procedures, and controls should be formally approved, regularly reviewed, and integrated into business operations. Organizations should establish governance structures, conduct routine training, measure control effectiveness, and ensure that risk management activities are repeatable regardless of personnel changes. Being able to achieve compliance at this level is a key factor.

Tier 4 – Adaptive

To attain Tier 4, organizations must move beyond compliance and actively measure cybersecurity performance. Security metrics (KPI/KPGs), threat intelligence, continuous monitoring, and automated detection capabilities should be used to drive decision-making. Risk management becomes data-driven, enabling the organization to adjust controls and processes based on evolving threats, business objectives, and lessons learned from incidents also feed process. The start of continuous improvement efforts are seen at this level.

Tier 5 – Optimizing

Achieving Tier 5 requires a culture of continuous improvement and innovation. Organizations should leverage advanced analytics, automation, artificial intelligence, threat intelligence sharing, and mature governance programs to anticipate and respond to emerging risks. Security is fully integrated into strategic planning, and lessons learned from incidents, audits, exercises, and industry developments are continuously used to enhance resilience and cybersecurity effectiveness. Innovation is a key driver at this level and often harder to achieve since it takes a good bit of investment into research and development of innovative ideas. You can also see this in many of the cybersecurity tooling companies delivering technologies that help implement controls by meeting your security objectives.

Progression Summary

Tier 1 → Tier 2: Build risk awareness and management involvement.
Tier 2 → Tier 3: Standardize and document security processes.
Tier 3 → Tier 4: Measure performance and adapt based on data.
Tier 4 → Tier 5: Continuously improve through innovation, automation, and strategic risk management.

This progression aligns with the maturity concepts described in the NIST Cybersecurity Framework (CSF) 2.0 and provides a practical roadmap organizations can use to mature their cybersecurity program over time. A quick one-pager image is below helping explain the concepts discussed above.
