What is FIPS Compliance: Differences

What is FIPS Compliance?

FIPS compliance means systems use approved security standards to protect data using validated cryptographic modules. “FIPS compliant” indicates alignment, while certified means formally validated. FIPS plays a key role in securing federal information systems under laws like the Information Technology Management Reform Act.

FIPS Compliant vs. Validated vs. Certified: What's the Difference?

FIPS compliant means a container image or software is configured to use FIPS-approved encryption algorithms under a Federal Information Processing Standard. However, it must be without independent verification of the cryptographic module. FIPS validated means the specific cryptographic module inside the image has passed CMVP testing under FIPS 140-2 or FIPS 140-3. Meanwhile, FIPS certified is a non-standard label often used to describe that validated status, not a separate classification.

Here’s the comparison between the three:

This distinction is critical in software supply chains: FIPS compliance applies at the image level, while FIPS validation applies at the cryptographic module level. Only validation provides verifiable assurance that encryption inside the container meets federal security standards.

FIPS Standards Breakdown: 140-2, 140-3, 197, 199, 200, and 201

FIPS standards are a set of publicly announced federal security standards developed by the National Institute of Standards and Technology for securing information systems used by U.S. federal government agencies and their contractors. These standards define encryption algorithms, security controls, identity systems, and risk classification models required to meet federal information security and compliance obligations.

Here’s how each specific FIPS standard functions within the overall security and compliance framework:

• FIPS 140-2: Cryptographic Module Security Requirements: Defines security requirements for cryptographic modules used in computer systems. It:

• Covers hardware, software, and firmware modules

• Introduces 4 levels of security based on physical and logical protections

• Enables FIPS 140-2 validation under the Cryptographic Module Validation Program (CMVP)

• Widely used in legacy systems, still marked as FIPS 140-2 validated

• FIPS 140-3: Updated Cryptographic Module Standard: Replaces FIPS 140-2 with stricter and modernized requirements. It

• Aligns with international standard ISO/IEC 19790

• Enhances testing rigor and validation processes

• Mandatory for newer information technology systems handling sensitive data

• Strengthens overall data security and computer system protection

• FIPS 197: Advanced Encryption Standard (AES): Defines the AES encryption algorithm, which is FIPS-approved for securing sensitive information. It:

• Supports 128-bit, 192-bit, and 256-bit keys

• Used in encryption protocols across government and enterprise systems

• Core requirement for organizations aiming to comply with FIPS encryption standards

• FIPS 199: Security Categorization of Information Systems: Establishes how to classify information systems based on impact levels. It:

• Defines Low, Moderate, and High levels of security

• Based on the impact on confidentiality, integrity, and availability

• Forms the foundation for risk-based security and compliance decisions

• FIPS 200: Minimum Security Requirements for Systems:Defines baseline security controls required for federal information systems. It:

• Covers areas like access control, incident response, and system integrity

• Works with NIST SP 800-53 control families

• Ensures systems meet mandatory federal security standards

• FIPS 201: Personal Identity Verification (PIV): Defines identity and access control standards for federal personnel. It:

• Standardizes secure identity credentials (PIV cards)

• Enables authentication across federal systems

• Critical for physical security and logical access control in government environments

Each of these standards plays a distinct role: cryptography (140 series), encryption algorithms (197), risk classification (199), baseline controls (200), and identity management (201). Together, they form a complete federal information security framework required under regulations like the Federal Information Security Modernization Act (FISMA).

How the CMVP Works from Accredited Lab Testing to NIST Validation Listing?

The Cryptographic Module Validation Program (CMVP) is the official process used to validate cryptographic modules against FIPS 140-2 and FIPS 140-3 standards. It is jointly operated by the National Institute of Standards and Technology and the Communications Security Establishment. The program ensures that cryptographic algorithms used in computer security systems meet federal security standards required by federal agencies and regulations such as the Federal Information Security Management Act (FISMA).

Here’s how the CMVP validation process actually works in practice:

• Module definition and scope establishment: The vendor first defines the cryptographic module, including its logical and physical security boundary. This step specifies the implemented cryptographic algorithms, supported operating environments, and enforced security measures such as key generation, storage, and access control, which are essential for secure use in computer systems.

• Engagement with an accredited testing laboratory (CSTL): The module is submitted to a Cryptographic and Security Testing Laboratory (CSTL) accredited under NVLAP. The CSTL operates independently to ensure consistent evaluation of security systems and validates that the module is prepared for formal testing under FIPS requirements.

• Comprehensive FIPS 140 testing and validation: The CSTL conducts detailed testing aligned to FIPS 140-2 or FIPS 140-3 requirements. This includes verification of approved cryptographic algorithms, validation of key management processes, and assessment of operational and physical security controls to ensure the module enforces required security measures under defined conditions.

• Validation report and submission to CMVP: After testing, the CSTL prepares a formal validation package, including a Security Policy document that defines approved modes of operation, usage constraints, and security boundaries. This package is submitted to CMVP for review, forming the basis for official validation.

• CMVP review and validation decision by NIST: NIST reviews the submitted documentation and test results to ensure full compliance with federal information processing standards. If gaps are identified, the submission is returned for clarification or correction. Only modules that fully meet the security requirements proceed to validation.

• Issuance of validation certificate and NIST listing: Once approved, the module receives a FIPS validation certificate and is listed on the official CMVP database. This listing includes module version, vendor, and approved environments, making it eligible for deployment in federal government organizations and regulated environments.

• Post-validation change control and lifecycle management: Any modification to the module, including updates to cryptographic algorithms, build configurations, or operating environments, can invalidate the certification status. Vendors must undergo revalidation or update processes to maintain compliance, ensuring continued trust in deployed security systems.

Who Must Comply with FIPS? Agencies, Contractors, and Beyond?

FIPS compliance applies to any organization that handles, processes, or secures federal information systems, especially where encryption and data protection are critical. It is mandatory for federal agencies and extends to contractors, service providers, and platforms that operate on their behalf. In practice, any environment using cryptographic modules in information technology to protect sensitive federal data must align with these compliance requirements.

1. Federal Agencies (Primary Obligation)

Federal government organizations must implement FIPS security standards in accordance with federal information security laws. This includes enforcing FIPS-approved cryptographic modules in information technology systems, applying defined security controls, and aligning information security programs with federal compliance requirements. FIPS compliance is mandatory for federal agencies except for systems explicitly designated as national security systems.

2. Federal Contractors and Service Providers (Contract-Driven Obligation)

Any contractor handling federal data or operating systems on behalf of federal agencies must comply with FIPS requirements as defined in contracts. This includes cloud providers, SaaS vendors, and managed service providers that process or store federal information. In these cases, FIPS compliance becomes a binding compliance standard, especially for encryption and system-level security.

3. Systems Processing Federal Information (Scope-Based Obligation)

Compliance applies to any information system that processes, stores, or transmits federal data, regardless of ownership or hosting location. This includes cloud environments, container platforms, and third-party infrastructure. The determining factor is the use of federal information within the system.

4. Organizations Under Federal Security Frameworks (Regulatory Alignment)

Organizations governed by federal information security programs must align with FIPS standards to meet baseline security and compliance standards. This ensures consistent implementation of security measures across regulated environments.

5. Vendors Targeting Federal Markets (Procurement Requirement)

Technology vendors must demonstrate FIPS compliance, especially FIPS 140 validation, to qualify for federal procurement. Without validated cryptographic modules, products are typically not accepted for use in federal systems.

6. Voluntary Adopters in Regulated Industries (Best-Practice Adoption)

Organizations outside the federal ecosystem often adopt FIPS standards as industry benchmarks for strong encryption and security systems. This is common in sectors such as finance and healthcare, where compliance standards demand high levels of data protection.

FIPS Security Levels for Cryptographic Modules Explained

FIPS 140 defines four security levels that specify how cryptographic modules must protect encryption processes within information systems:  

• Level 1 requires approved cryptographic algorithms with basic integrity checks.  

• Level 2 introduces tamper-evident mechanisms and role-based authentication.  

• Level 3 enforces tamper-resistance, secure key storage, and identity-based access control.  

• Level 4 provides the highest protection with environmental failure detection and complete physical security enforcement.

In container-based supply chains, these levels apply strictly to the cryptographic module embedded inside the image, not the entire container or application. A system achieves FIPS compliance only when it uses a FIPS validated module operating in approved mode, and the required level is determined by system classification under FIPS 199 and specific federal security requirements.

Is FIPS Compliance Mandatory for Private Sector Organizations?

FIPS compliance is not mandatory for private sector organizations by default. It becomes mandatory only when a private entity handles federal information systems, processes federal data, or operates under contracts with federal agencies. Otherwise, FIPS remains a voluntary set of standards used to strengthen encryption and security practices.

Here’s when FIPS compliance applies and when it does not:

• Mandatory when working with federal agencies: Private organizations must comply when contracted by federal agencies. FIPS requirements become enforceable through agreements, especially for encryption and system-level security controls.

• Mandatory when handling federal information: Any system processing or storing federal data must align with FIPS standards, including the use of FIPS-approved cryptographic modules and defined security measures.

• Not mandatory for independent operations: Private companies without federal data or contracts are not required to comply with FIPS and can follow other industry standards.

• Adopted as a security benchmark: Many organizations voluntarily implement FIPS to strengthen encryption and align with recognized security and computer system standards.

• Compliance vs certification distinction: “FIPS compliant” indicates alignment with standards, while validation or certification refers to tested cryptographic modules under FIPS 140 requirements.

FIPS 140-2 vs. 140-3: The 2026 Transition Deadline Explained

FIPS 140-2 and FIPS 140-3 are federal information processing standards that define security requirements for cryptographic modules in information systems. The 2026 transition changes their regulatory acceptance. After September 21, 2026, FIPS 140-2 validated modules will move to the Historical List and no longer meet current compliance requirements. FIPS 140-3 becomes the only standard required for compliance with FIPS for federal agencies and their contractors.

Here’s the exact difference and what the transition enforces:

The transition enforces a module-level upgrade across the software supply chain. Organizations must replace FIPS 140-2 validated cryptographic modules with FIPS 140-3 validated modules to maintain compliance standards, meet procurement requirements, and align with evolving federal security expectations.

Identifying outdated modules at scale requires deep supply chain visibility. This is where platforms like CleanStart help by exposing container contents and highlighting non-compliant dependencies.

FIPS Compliance by Industry: Healthcare, Finance, and Defense

Industries such as healthcare, finance, and defense apply FIPS differently. However, all rely on validated cryptographic modules, controlled builds, and verifiable SBOMs to ensure critical security across systems handling sensitive data.

1. Healthcare Industry (Protected Data and System Integrity)

Healthcare systems handling patient data must secure encryption within applications and containerized workloads. FIPS compliance applies when these systems integrate with federal programs or regulated infrastructure. Organizations must ensure that cryptographic modules in use are FIPS validated and that SBOMs clearly identify encryption libraries to prevent exposure through vulnerable or non-compliant components.

2. Financial Services (Transaction Security and Encryption Assurance)

Financial platforms depend on strong encryption to protect transactions and user data. FIPS compliance becomes essential when systems require high-assurance encryption or interact with government-backed financial frameworks. In practice, this requires enforcing FIPS-approved cryptographic modules within software dependencies and container builds, ensuring that encryption across systems meets defined security standards.

3. Defense and National Security (Strict Enforcement and Controlled Environments)

Defense environments require strict adherence to FIPS because these standards apply to national security systems and classified operations. Every cryptographic module used in software, infrastructure, or container images must be validated and controlled. Compliance is enforced through secure build pipelines, validated modules, and tightly governed deployment environments, ensuring that all systems meet the highest level of security requirements.

How to Become FIPS Compliant: A Step-by-Step Guide

FIPS defines how cryptographic modules must secure data in accordance with federal information security requirements. To become FIPS compliant, organizations must move beyond “FIPS compliant” claims and ensure validated implementation across their software supply chain.

Here’s how organizations achieve compliance with FIPS in practice:

• Understand FIPS compliance requirements and scope: Identify where FIPS applies within your systems. This includes environments that process federal data or must align with federal compliance standards and security requirements.

• Assess cryptographic modules and dependencies: Review all cryptographic modules in information technology systems. Replace any non-approved or unverified implementations with FIPS approved modules.

• Use FIPS-validated cryptographic modules: Compliance with FIPS requires modules validated under FIPS 140 standards. The difference between FIPS compliant vs validated is critical, as only validated modules meet formal requirements.

• Enforce approved cryptographic configurations: Ensure systems operate only in approved mode, disabling unsupported algorithms and enforcing security controls across environments.

• Document validation and maintain audit readiness: Maintain records of validation, configurations, and system controls to demonstrate compliance during audits and federal engagements.
