In today’s healthcare landscape, where technology and connectivity play a critical role, the FDA’s 510(k) guidance has become more than a regulatory step—it’s a safeguard for patients and a benchmark for manufacturers. Recent updates emphasize cybersecurity as a mandatory element of medical device submissions, ensuring safety and resilience against modern threats.
Understanding the 510(k) Framework
The 510(k) submission, also known as Premarket Notification, is the most common route for medical devices to gain market clearance in the United States. Manufacturers use this process to demonstrate that their device is substantially equivalent to an already legally marketed device, known as a predicate. This equivalence ensures that the new product is just as safe and effective as its predecessor.
There are three main types of 510(k) submissions:
Submission and Review Process
Since October 2023, nearly all 510(k) submissions are required to be electronic, either through the FDA’s eSTAR template or as an electronic copy. Once submitted, the FDA assigns a unique “K-number” and issues an acknowledgment letter confirming the application’s receipt and format.
The review process begins with the Acceptance Review, where FDA checks the submission for completeness. If it does not meet minimum requirements, a Refuse to Accept notice may be issued. Manufacturers then have 180 days to resolve deficiencies.
Once accepted, the FDA proceeds to a Substantive Review, during which experts evaluate the safety, effectiveness, and equivalence of the device. This stage typically lasts up to 90 FDA calendar days, though requests for additional information can extend the timeline.
Cybersecurity as a Core Requirement
One of the most significant changes in recent years is the incorporation of cybersecurity into the 510(k) process. In 2025, cybersecurity is no longer a supplemental consideration—it is an essential component of compliance.
Devices that fall under the category of “cyber devices” must demonstrate security throughout their lifecycle. These are generally defined as devices containing software, connectivity features, or modules that could expose them to cyber risks.
Key Cybersecurity Requirements:
Achieving 510(k) clearance is not only about meeting technical requirements but also about efficient preparation. Manufacturers can improve their chances of success by following a few best practices:
Regulatory Step
Key Compliance AreasSubmission Requirements
Predicate device, device description, SBOM, cybersecurity testing, documentation
Electronic Submission
eSTAR or eCopy, acknowledgment letter, K-number
Review Timeline
Acceptance Review → 90-day Substantive Review
Cybersecurity Elements
SBOM, penetration testing, risk assessments, lifecycle documentation
Best Practice Tips
Early planning, expert guidance, updated records
Final Thoughts
The 510(k) process continues to be the backbone of medical device approvals in the United States. However, in 2025, cybersecurity has become inseparable from compliance. Manufacturers must now treat digital safety as a design priority, not a checklist item. By proactively integrating cybersecurity testing, maintaining transparent documentation, and following FDA’s evolving guidance, companies can ensure both faster approvals and safer devices for patients.

This equivalence ensures that the new product is just as safe and effective as its predecessor.
There are three main types of 510(k) submissions:
- Traditional 510(k): The standard route for new devices or those without an identical predicate.
- Abbreviated 510(k): A faster process available when FDA-recognized guidance or consensus standards apply.
- Special 510(k): Reserved for modifications to a manufacturer’s own previously cleared device.
Submission and Review Process
Since October 2023, nearly all 510(k) submissions are required to be electronic, either through the FDA’s eSTAR template or as an electronic copy. Once submitted, the FDA assigns a unique “K-number” and issues an acknowledgment letter confirming the application’s receipt and format.

Devices that fall under the category of “cyber devices” must demonstrate security throughout their lifecycle. These are generally defined as devices containing software, connectivity features, or modules that could expose them to cyber risks.
Key Cybersecurity Requirements:
- Identify Cyber Devices: Determine whether the product qualifies as a cyber device, which includes any software-driven product with connectivity, even through hidden modules such as debug ports.
- Develop a Software Bill of Materials (SBOM): A machine-readable list of all software components used in the device, including open-source, third-party, and proprietary elements. This improves transparency and vulnerability management.
- Conduct Penetration Testing and Risk Assessments: Evaluate the device under simulated cyber-attack conditions to identify vulnerabilities in networks, firmware, communication channels, and applications.
- Maintain Comprehensive Documentation: Clearly record findings, risk assessments, mitigation steps, retesting results, and monitoring activities. This demonstrates to the FDA that security has been addressed across the entire device lifecycle.
Achieving 510(k) clearance is not only about meeting technical requirements but also about efficient preparation. Manufacturers can improve their chances of success by following a few best practices:
- Plan Early: Incorporate cybersecurity into the design and development phases rather than leaving it for later stages. Early planning reduces the risk of costly redesigns.
- Maintain Accurate Documentation: Keep SBOMs, test results, and design records organized and current. Incomplete or outdated documentation is one of the most common reasons for delays.
- Engage Experts: Collaborating with cybersecurity testing firms or regulatory consultants can streamline the process, especially when navigating complex security expectations.
- Stay Aligned with FDA Guidance: Regularly reviewing updated FDA documents and incorporating recognized standards ensures submissions meet evolving requirements.
