When organizations evaluate FIPS 140-3 validation, the conversation often begins with cost and timeline. Certification requires planning, engineering effort, testing, and coordination with the Cryptographic Module Validation Program (CMVP), making it easy to view validation primarily as a compliance expense.

Given these requirements, it is understandable that organizations question whether the investment is justified, particularly when product teams are focused on accelerating releases, entering new markets, and meeting customer demands.

However, that perspective overlooks a more important consideration: the business value that validation can create. For organizations that sell into federal, defense, critical infrastructure, and other regulated markets, validation can open new markets, strengthen product security, reduce compliance friction, and enhance competitive positioning.

This post is the fifth and final installment in our Deconstructing FIPS 140-3: 5 Myths and Realities series, where we examine common misconceptions surrounding FIPS 140-3 and what organizations should understand before beginning the validation process.

Myth #5: “The Cost and Timeline of FIPS Validation Aren’t Justified.”

FIPS 140-3 validation requires an investment of time, resources, and budget. For some organizations, those costs can appear difficult to justify, especially when viewed only as a compliance requirement.

However, the more important question is “What is the cost of not addressing FIPS 140-3”

Reality: Validation Is an Investment in Market Access, Product Readiness, and Risk Reduction

FIPS 140-3 validation is not simply an administrative exercise. It provides independent assurance that a cryptographic module has been evaluated against the CMVP’s security requirements. For organizations selling into government and regulated environments, the absence of a validation can result in:

• Exclusion from certain solicitations or procurement opportunities
• Delayed customer deployments
• Restrictions on where a product can be deployed
• Lost opportunities to competition
• Repeated customer-specific security reviews
• Delayed entry into new government or regulated markets

When viewed through this lens, the investment in validation should be weighed against the opportunities it enables and the risks it helps mitigate.

Understanding the Real Timeline Risk

Another common misconception is that all FIPS validations require the same level of effort and follow the same path to validation.

In reality, organizations have several options depending on their product architecture, business objectives, and deployment requirements. These may include:

• Full FIPS 140-3 validation
• Private-labeling or Rebrands
• Cryptographic Algorithm Validation Program (CAVP) testing
• Entropy Source Validation (ESV)

Not all approaches are equal in scope, complexity, cost, or timeline.

Organizations sometimes postpone validation activities because they want to avoid investing resources before a customer explicitly requires FIPS validation. However, when FIPS requirements emerge late in the product lifecycle, engineering teams may need to revisit architectural decisions, modify cryptographic implementations, restructure documentation, or develop a separate product configuration for validation. These changes can disrupt development schedules that were never designed around certification requirements.

The result is often not only a larger validation budget, but a significantly larger product development budget. By evaluating validation options and requirements early, organizations can make more informed design decisions, minimize rework, and avoid costly schedule impacts later in the product lifecycle.

The Real Business Case for FIPS 140-3

A Strategic Approach to Validation

FIPS 140-3 validation requires time, resources, and investment. However, early planning can make the process more predictable and reduce costly surprises.

By incorporating validation into product development from the beginning, organizations can identify gaps earlier, minimize rework, better manage timelines, and align certification efforts with business objectives.

Ultimately, the right question is not simply, “How much will FIPS 140-3 cost?” but “What value will validation create for our product and market?”

For organizations that need FIPS validation to compete, the cost of not being validated may be significantly greater than the cost of validation itself.

Organizations that already have a FIPS 140-2 validation may assume that their work is finished. After all, the product already went through a formal validation process, so why would another validation be necessary?

The answer is that FIPS 140-2 and FIPS 140-3 are different standards. FIPS 140-3 replaced FIPS 140-2 as the current standard for new validations and introduced updated requirements for evaluating cryptographic modules. With that and the looming FIPS 140-2 sunset date approaching, all vendors considering an approach for FIPS 140 will need to validate to the newest version of the publication.

This post is the fourth installment in our Deconstructing FIPS 140-3: 5 Myths and Realities series, where we examine common misconceptions surrounding FIPS validation and explain what organizations should understand before beginning the certification process.

Myth #4:

“Our product has a FIPS 140-2 validation, so we don’t need FIPS 140-3.”

At first glance, this assumption seems reasonable. If a product has already completed FIPS validation, it can be easy to think that the existing validation automatically carries over to the newer standard.

Reality:

A FIPS 140-2 validation does not automatically make a product FIPS 140-3 validated.

FIPS 140-2 was the standard used to validate cryptographic modules for many years. FIPS 140-3 is its successor and was developed to update the requirements and align the U.S. standard more closely with international standards.

While FIPS 140-3 builds on many of the concepts found in FIPS 140-2, it also includes updated requirements and changes to how cryptographic modules are evaluated. FIPS 140-2 and even FIPS 140-3 validations have a sunset date, traditionally 5 years. However, all remaining FIPS 140-2 validations will be automatically sunset on Sept. 21, 2026.

For vendors selling into the U.S. federal government, the CMVP states that all modules with a status designation of Historical “should not be included by Federal Agencies in new procurements.”

If an organization has already invested significant time and resources into obtaining a FIPS 140-2 validation, it is understandable to assume that the existing validation should be sufficient for the newer standard. However, a FIPS 140-2 certificate does not simply become a FIPS 140-3 certificate. The two standards have different requirements, and organizations need to understand what their existing validation means and what requirements apply to their specific product and use case.

Validation & Boundaries

If an organization has already invested significant time and resources into obtaining a FIPS 140-2 validation, it is understandable to assume that the existing validation should be sufficient for the newer standard. However, a FIPS 140-2 certificate does not simply become a FIPS 140-3 certificate. The two standards have different requirements, and organizations need to understand what their existing validation means and what requirements apply to their specific product and use case.

Another important consideration is that FIPS validation applies to a specific cryptographic module and its defined configuration. It is not a blanket certification that automatically covers every version or configuration of a product.

This means that when a product is updated or a new version is released, organizations need to understand whether those changes affect the scope of the existing validation. The fact that an earlier version was validated does not necessarily mean that a newer version has the same validation status.

Moving From One Standard to the Next

For organizations with an existing FIPS 140-2 validation, the transition to FIPS 140-3 does not necessarily mean starting from scratch. The existing validation can provide a useful foundation for understanding what may need to change.

Planning early can help organizations identify differences between their current FIPS 140-2 validation and the requirements of FIPS 140-3. This can help teams anticipate potential design, documentation, and testing impacts before beginning a new validation effort.

The Takeaway

Having a FIPS 140-2 validation is valuable, but it should not be confused with having a FIPS 140-3 validation. As organizations plan new products, product updates, or future validation efforts, understanding the differences between the two standards is an important first step.

FIPS validation is not simply a label that applies to every version of a product. The applicable standard, validated module, configuration, and current requirements all matter.

Understanding where your product stands today can help ensure that your next step is the right one.

By the time organizations begin planning for FIPS 140-3 validation, they usually understand that documentation is required. Security policies, design documentation, finite state models, and other artifacts are all necessary components of the validation package.

Because of the volume of required documentation, it’s easy to assume that FIPS validation is primarily an exercise in writing documents. In reality, documentation is only one part of a much broader process that evaluates how a cryptographic module is designed, implemented, tested, and maintained.

This post is the third installment in our Deconstructing FIPS 140-3: 5 Myths and Realities series, where we examine common misconceptions surrounding FIPS validation and explain what organizations should understand before beginning the certification process.

Myth #3:

“FIPS validation is just a documentation exercise.”

At first glance, this assumption seems reasonable. Organizations often see the extensive list of required documents and conclude that success depends primarily on producing enough paperwork.

While documentation is essential, it exists to support something much larger such as demonstrating that a cryptographic module satisfies the security requirements defined by FIPS 140-3.

Reality:

Documentation supports validation but it doesn’t replace engineering, testing, or compliance.

A successful FIPS validation requires far more than completed documents. Every document must accurately reflect the implementation of the cryptographic module and align with the evidence generated throughout the validation process.

Organizations should expect work across multiple areas, including:

• Cryptographic module architecture and boundary definition
• Approved algorithm implementation
• Security function design
• Role, service, and authentication analysis
• Self-tests and operational testing
• Documentation required by the Cryptographic Module Validation Program (CMVP)
• Independent testing performed by an accredited laboratory

Documentation ties these pieces together, but it cannot compensate for implementation gaps or design issues discovered during testing. If engineering decisions and documentation do not align, the validation process often slows as teams revisit product design, update documentation, or correct implementation issues. The overall process requires close collaboration between engineering, documentation, testing, and program management to keep the project moving swiftly.

Why This Myth Persists

Documentation is often the most visible part of the validation process. Teams spend significant time preparing security policies, reviewing technical descriptions, and responding to documentation feedback, making it appear that paperwork drives the project.

In reality, documentation reflects decisions that have already been made throughout product development. Every requirement documented must be supported by the module’s actual behavior and verified during laboratory testing.

Organizations that wait until the documentation phase to identify design issues, frequently discover that changes are more expensive and time-consuming than if they had been addressed earlier.

A Better Approach

The most successful FIPS projects treat documentation as one component of an integrated validation strategy—not the final task before submission.

Planning early allows organizations to:

• Define the cryptographic boundary correctly.
• Identify design issues before formal testing begins.
• Ensure documentation accurately reflects implementation.
• Reduce rework during laboratory review.
• Keep engineering, testing, and documentation aligned throughout the project.

Approaching validation this way helps minimize delays while improving confidence that the module will successfully complete evaluation.

Organizations that are unsure where to begin don’t have to navigate the process alone. Corsec’s FIPS 140-3 Assessments help teams evaluate their current readiness, identify potential gaps early, and develop a practical path toward validation before formal testing begins.

Looking Ahead

Documentation is an essential part of every FIPS 140-3 validation, but it is only valuable when supported by sound engineering, accurate implementation, and successful testing. Viewing validation as a documentation-only effort can lead organizations to underestimate the technical work required and introduce unnecessary delays later in the project.

In the next installment of this series, we’ll examine another common misconception:

Myth #4: Once a product is FIPS validated, it never needs to be updated or maintained.
