Following recent FDA QMSR updates aligned with ISO 13485, the FDA has intensified its refusal-to-accept (RTA) criteria for 510(k) submissions. Software Bill of Materials (SBOM) or a formal Secure Product Development Framework (SPDF) is required for devices classified as ‘cyber devices’ under Section 524B. FDA and CISA advisories show a consistent trend of high-severity vulnerabilities in medical devices. FDA submissions may face RTA if required cybersecurity documentation is missing or insufficient, with weak risk assessments among the top deficiencies. And this is why Qualysec Technologies is here to tell you about the FDA 510k Cybersecurity Gap Analysis.
This guide provides a practical framework to conduct an FDA 510k Cybersecurity Gap Analysis – an evaluation of the security of your device based on the Postmarket Management of Cybersecurity in Medical Devices guidance (as of 2025) and aligned with FDA QMSR (transitioning from 21 CFR Part 820 to ISO 13485:2016). We are going to understand some technical concepts and pro tips to develop your knowledge.
Pro Tip: Use gap analysis at the design stage – do not wait to find out about it during pre-submission audits.

Must-Haves for 2026 510(k) Submissions
To avoid a “Refusal to Accept” (RTA) or significant delays under the latest Section 524B compliance and QMSR standards, your submission must include:
Comprehensive Software Bill of Materials (SBOM) – A machine-readable (SPDX or CycloneDX) list of all open-source and third-party software parts.
Formal Threat Model – An analytical approach to determining the possible attack vectors and capturing the security controls that are in place to prevent them.
Vulnerability Exploitability eXchange (VEX) – Documentation to help you understand which vulnerabilities you found in your SBOM can be exploited in your specific environment.
Postmarket Management Plan – The precise roadmap on how you will deliver patches and updates in time upon the device entering clinical use.
eSTAR Cybersecurity Attachments – All documentation must be formatted for seamless integration into the FDA’s mandatory eSTAR electronic submission template.
Step 1 – List FDA Security Rules
Start with the requirements of the FDA. Among others, essential areas are access control, data protection, and threat handling. The access control means that only the approved individuals can use the device, such as by using a password and a fingerprint. To protect data, powerful codes are used for Patient Safety Impact Analysis.
Start by mapping your device to the FD&C Act Section 524B requirements to prove your device is “Cybersecure by Design.” Write a list of basic rules of your device. As an example, a blood pressure monitor needs a safe Bluetooth link.
FDA Requirements Table:
Area
What the FDA Asks
Simple Example
Access
Use two checks like a password + code
The doctor logs in to the app securely
Data Safe
Encrypt data at rest and in transit (e.g., AES-256, TLS 1.2+)
Patient data hides in the cloud
Threats
List all weak spots
Plan for hack attempts
Updates
Easy fix for bugs
Auto-download safe software
Step 2 – Test Your Device Setup
Now, write down your device’s parts. Record device software (such as applications), and hardware (such as chips and Wi-Fi). For example, in the case of a wearable heart tracker, indicate the version of the app, the battery chip, and the phone connection.
Determine the presence of known bugs in parts using SCA tools and vulnerability databases (e.g., NVD). This listing indicates what is there and what is not. Fix simple things to start with, such as old software. A lot of devices fail at this point since teams do not take into consideration this list.
Step 3 – Find Risks and Threats
Imagine the worst that might occur, such as an attack by a hacker. Use easy models to see who attacks, how they do it, and what harm they can cause. Rate each from low to high. For example, in the case of a pump device, a remote dose change by a digital glitch or attack is of high risk.

Step 4 – Weakness Test
Check your set-up. Check without executing code, such as scanning it with free tools, to detect holes. Test the network by observing data packets. Test a false attack, such as excessive logins, to determine whether it blocks or not.
In the case of hardware, insert plug-in testers in ports. Note what breaks. A real-life example – a monitor team discovered a Bluetooth leak in this manner and patched it in a short period of time. Make sure to record all the steps and dates.
Pro Tip: Think like an attacker and simulate realistic threat scenarios – attempt common tricks as you start.
Step 5 – Make Repairs and Preplan
Make a fix list of who fixes and when, per weak spot. Prepare a report with pre-fix and post- fix evidence. Track progress weekly. Finalize with FDA-ready documents, such as a risk summary. This roadmap ensures your project is on schedule.
Pro Tip: Announce fixes with your team as early as possible to avoid a last-minute rush.

Q.Does my 510(k) need a VEX (Vulnerability Exploitability eXchange)?
Yes. In 2026, the FDA increasingly expects a clear vulnerability impact context alongside SBOM (VEX is commonly used for this purpose, but not explicitly mandated)
Q.How long does a 510k cybersecurity gap analysis take?
The average time of a 510k cybersecurity gap analysis is between 4 and 8 weeks. This will be based on your device complexity and the availability of security documents. Basic devices, such as basic monitors, could be completed in a shorter period of around 4 weeks. Collect the device information, run tests, and prepare a report. Begin on time in your project to make it fit into your schedule without stress.
Q.Which tools are the best to use in testing medical device cybersecurity?
The best medical device cybersecurity testing tools are Burp Suite to test web apps, APIs, Wireshark to observe network traffic to detect leaks, and Checkmarx to scan code without executing it. To construct SBOMs using Syft to create software lists. These are complementary or low-cost starters. Choose depending on your device- Wireshark in case of wireless networks, Burp in case of cloud networks. They assist in locating bugs quickly and in proving your fixes to the FDA.
Q.Will the FDA 510k in 2026 require SBOM?
Yes, as of 2026, an SBOM is mandatory for FDA 510k submissions for devices classified as “cyber devices” under Section 524B. It is a complete list of software components and weak spots of your device. Use the guidelines and append VEX files to display the threat of exploits. Include it in your information security plan. This assists the FDA in the process of reviewing at a faster rate and early identification of supply chain problems.
Q.What is the difference between an FDA 510k cybersecurity gap analysis with ISO 27001?
The FDA 510k cybersecurity gap analysis is specifically based on your medical device, where risks to patient health, such as hacking a pacemaker, are checked. It is comparable to the FDA regulations for approving 510(k). ISO 27001 is larger- it includes the entire info security of your business, such as office computers. Gap analysis is fast and device-specific, while ISO requires complete audits and certification. Firstly, gap analysis, then ISO, to protect the business on a broader scale. Both are aids, yet the FDA is a must-have on devices.
Q.Is cybersecurity gap analysis for small medtech startups affordable (510k)?
Yes, it is affordable to a small medtech startup to have a 510k cybersecurity gap analysis. Basic ones begin as low as $10,000, in installments. It avoids wasting money in the long-term as it accelerates FDA approval and eliminates future fixes. Apply free tools in the initial procedures, and recruit professionals for reports. The faster the market entry, the higher the returns that many startups can get.
