Our approach to threat modeling
In this series, you’ll hear directly from Vanta’s Security, Enterprise Engineering, and Privacy, Risk, & Compliance Teams to learn about the team’s approach to keeping Vanta — and most importantly, our customers — secure.
The following post comes from our Security Team and explains our approach to threat modeling.
What is threat modeling?
Threat modeling is the process of identifying and understanding the potential threats and risks that can impact a given business, system, network, or feature.
The goal of threat modeling is to make better decisions. We do this by building a better mental model of the world, keeping things in mind such as potential attacker’s profiles, motivation, goals, and likely attack vectors. Many of us model threats every day—when making decisions such as choosing to buckle your seatbelt, looking both ways before you cross the street, and more.
How does Vanta approach threat modeling?
At Vanta, we use threat modeling as a tool to help share knowledge and improve our mental model of Vanta as a company, and of the environment in which we operate. These exercises are most frequently run (though not always) by the Security team, and are held on recurring cadences and on an as-needed basis.
We don’t maintain a canonical “threat model” at any given point in time. Instead, we view the exercise itself as the primary mechanism through which we benefit. This is because the discussion that arises during a threat modeling exercise is what improves our mental model and enables us to make better decisions.
In other words: “Threat models are useless. Threat modeling is essential.”
When does the Vanta security team threat model?
We view threat modeling as a team and organizational muscle that requires regular exercise. It can be fun, enlightening and interesting! This means we get together for threat modeling exercises on at least a monthly basis, if not more frequently. Sometimes we'll threat model a given feature, and other times we’ll pick a sample scenario to model and discuss. For some added fun, sometimes we’ll even get together to model threats around a given theme, event, or season.
In addition, we strive to include a wide range of teammates across Vanta in our exercises. This can depend on the topic at hand but often includes individuals from our Enterprise Engineering, Privacy, Risk, & Compliance, Engineering, and Product teams, as well as from our operational and customer-facing teams. Not only does this help evolve our individual mental models of risk, but it also widens our collective lens on hidden risks and opportunities for improvement across the organization to make more informed decisions.
Keep in mind that if you’re focusing on a specific feature or project, it’s helpful to start as early as possible, such as in the design phase. This lowers the cost of any big changes that need to be made.
What are the core steps you follow?
Here are the core steps we follow for our threat modeling exercises:
1. Define your goals
Discuss and agree upon what your collective goals are for your threat modeling exercise, and jot this down to help ensure all teammates are on the same page. This could be to model threats for a given feature or project, or something more broad—such as to help inform your team’s planning for a given quarter. Defining your goals up front can help you keep your discussion more focused.
2. Define your scope
Identify the data, systems, and processes at hand that you’re protecting and understand how they’re used, as well as any dependencies. This helps your team to go into greater depth than they could if you had to keep expanding the breadth of your focus.
3. Identify threats
Brainstorm the most significant threats that could compromise the confidentiality, integrity, or availability of your system. While we often consider external attackers, be sure to also consider internal actors, whether intentional or unintentional.
4. Identify controls
Enumerate the controls that are either in place or could be put into place to mitigate each threat, including both preventative and detective controls.
5. Identify gaps
Model in the gaps that could result in controls failing to block a particular threat. For example, anti-malware doesn’t always detect the malware. What would happen next? What would the next stage of the attack be? Do you have further controls for that step?
6. Next steps
Based on the discussion, identify action items and make sure you address them. Walk away better informed and make good decisions!
During our threat modeling exercises, we use diagramming tools to communicate and connect information and create a clear visual representation of your threat model. This is particularly beneficial during exercises that incorporate a variety of stakeholders—we view these diagrams as primarily for those who are in the room instead of as an artifact for the future.
While we’ve experimented with a variety of tools, we tend to use Deciduous or a lightweight model in FigJam that allows us to collaborate and communicate effectively.
Tips for threat modeling
An important point to remember is that there are many approaches to threat modeling. Our recommendation is to find what works best for your organization to ensure that you’re able to threat model effectively when you need it most, instead of running an arduous exercise that’s both operationally challenging and outdated quickly.
Here are a few suggestions we have for ensuring threat modeling exercises run smoothly:
- Your team: Assemble a cross-functional team to ensure you’re incorporating diverse perspectives—such as teammates across your security, engineering, business, and operations teams. This can help reduce observational bias (e.g. the streetlight effect) when modeling threats. Be sure to share context beforehand or at the start of the session, especially if it’s your organization’s first time running a threat modeling exercise.
- Your roles: Assign clear roles and responsibilities ahead of time. For example, decide who’ll help run the exercise, update the threat model in real-time, and identify anyone who might play a specific role—such as teammates who represent the perspectives of the adversary, defender, developer, etc.
- Your tools: Identify which tools you’ll use and ensure you’re familiar with how they work prior to threat modeling. Remember, the point is to help create a high-bandwidth information session, not necessarily to capture your discussion for later.
Additional resources
Our goal is to make more informed decisions every day, and we hope you find threat modeling as fun, interesting, and valuable of an exercise as we do.

Determine if you need to comply with GDPR
Not all organizations are legally required to comply with the GDPR, so it’s important to know how this law applies to your organization. Consider the following:
Do you sell goods or services in the EU or UK?
Do you sell goods or services to EU businesses, consumers, or both?
Do you have employees in the EU or UK?
Do persons from the EU or UK visit your website?
Do you monitor the behavior of persons within the EU?
Document the personal data you process
Because GDPR hinges on the data you collect from consumers and what your business does with that data, you’ll need to get a complete picture of the personal data you’re collecting, processing, or otherwise interacting with. Follow these items to scope out your data practices:
Identify and document every system (i.e. database, application, or vendor) that stores or processes EU- or UK-based personally identifiable information (PII).
Document the retention periods for PII in each system.
Determine whether you collect, store, or process “special categories” of data, including:
Determine whether your documentation meets the GDPR requirements for Records of Processing Activities, that include information on:
Determine whether your documentation includes the following information about processing activities carried out by vendors on your behalf:
Determine your legal grounds for processing data
GDPR establishes conditions that must be met before you can legally collect or process personal data. Make sure your organization is meeting the conditions listed below:
For each category of data and system/application, determine the lawful basis for processing based on one of the following conditions:
Review and update current customer and vendor contracts
For your organization to be fully GDPR compliant, the vendors you use must also maintain the privacy rights of your users’ and those rights should be reflected in your contracts with customers:
Review all customer and in-scope vendor contracts to determine that they have appropriate contract language (i.e. Data Protection Addendums with Standard Contractual Clauses).
Determine if you need a Data Protection Impact Assessment
A Data Protection Impact Assessment (DPIA) is an assessment to determine what risks may arise from your data processing and steps to take to minimize them. Not all organizations need a DPIA, the following items will help you determine if you do:
Identify if your data processing is likely to create high risk to the rights and freedoms of natural persons. Considering if your processing involves any of the following:
Clearly communicate privacy and marketing consent practices
A fundamental element of GDPR compliance is informing consumers of their data privacy rights and requesting consent to collect or process their data. Ensure your website features the following:
A public-facing privacy policy which covers the use of all your products, services, and websites.
Notice to the data subject that include the essential details listed in GDPR Article 13.
Have a clear process for persons to change or withdraw consent.
Update internal privacy policies
Ensure that you have privacy policies that are up to the standards of GDPR:
Update internal privacy notices for EU employees.
Have an employee privacy policy that governs the collection and use of EU and UK employee data.
Determine if you need a data protection officer (DPO) based on one of the following conditions:
Review compliance measures for external data transfers
Under GDPR, you’re responsible for protecting the data that you collect and if that data is transferred. Make your transfer process compliant by following these steps:
If you transfer, store, or process data outside the EU or UK, identify your legal basis for the data transfer. This is most likely covered by the standard contractual clauses.
Perform and document a transfer impact assessment (TIA).
Confirm you comply with additional data subject rights
Ensure you’re complying with the following data subject rights by considering the following questions:
Do you have a process for timely responding to requests for information, modifications, or deletion of PII?
Can you provide the subject information in a concise, transparent, intelligible, and easily accessible form, using clear and plain language?
Do you have a process for correcting or deleting data when requested?
Do you have an internal policy regarding a Compelled Disclosure from Law Enforcement?
Determine if you need an EU-based representative
Depending on how and where your organization is based, you may need a representative for your organization within the European Union. Take these steps to determine if this is necessary:
Determine whether an EU representative is needed. You may not need an EU-rep if the following conditions apply to your organization:
If the above conditions do not apply to you, appoint an EU-based representative.
Identify a lead data protection authority (DPA) if needed
GDPR compliance is supervised by the government of whatever EU member-state you’re operating in. If you’re operating in multiple member-states, you may need to determine who your lead data protection authority is:
Determine if you operate in more than one EU state.
If so, designate the supervisory authority of the main establishment to act as your DPA.
Implement employee training
Every employee in your organization provides a window for hackers to gain access to your systems and data. This is why it's important to train your employees on how to prevent security breaches and maintain data privacy:
Provide appropriate security awareness and privacy training to your staff.
Integrate data breach response requirements
GDPR requires you to create a plan for notifying users and minimizing the impact of a data breach. Examine your data breach response plan, by doing the following:
Create and implement an incident response plan which includes procedures for reporting a breach to EU and UK data subjects as well as appropriate data authorities.
Establish breach reporting policies that comply with all prescribed timelines and include all recipients (i.e. authorities, controllers, and data subjects).
Implement appropriate security measures
Have you implemented encryption of PII at rest and in transit?
Have you implemented pseudonymization?
Have you implemented appropriate physical security controls?
Have you implemented information security policies and procedures?
Can you access EU or UK PII data in the clear?
Do your technical and organizational measures ensure that, by default, only personal data that are necessary for each specific purpose of the processing are processed?
Streamline GDPR compliance with automation
GDPR compliance is an ongoing project that requires consistent upkeep with your system, vendors, and other factors that could break your compliance. Automation can help you stay on top of your ongoing GDPR compliance. The following items can help you streamline and organize your continuous compliance:
Explore tools for automating security and compliance.

Pre-work for your SOC 2 compliance
Choose the right type of SOC 2 report:
Do you sell goods or services to EU businesses, consumers, or both?
Do you sell goods or services to EU businesses, consumers, or both?
Do you sell goods or services to EU businesses, consumers, or both?
Determine the framework for your SOC 2 report. Of the five Trust Service Criteria in SOC 2, every organization needs to comply with the first criteria (security), but you only need to assess and document the other criteria that apply. Determining your framework involves deciding which Trust Service Criteria and controls are applicable to your business using our Trust Service Criteria Guide.
Estimate the resources you expect to need. This will vary depending on how closely you already align with SOC 2 security controls, but it can include several costs such as:
Compliance software
Engineers and potentially consultants
Security tools, such as access control systems
Administrative resources to draft security policies
Auditing for your compliance certification
Choose the right type of SOC 2 report:
Do you sell goods or services to EU businesses, consumers, or both?
Do you sell goods or services to EU businesses, consumers, or both?
Do you sell goods or services to EU businesses, consumers, or both?
Work toward SOC 2 compliance
Begin with an initial assessment of your system using compliance automation software to determine which necessary controls and practices you have already implemented and which you still need to put in place.
Review your Vanta report to determine any controls and protocols within the “Security” Trust Service Criteria that you do not yet meet and implement these one by one. These are multi-tiered controls across several categories of security, including:
CC1: Control Environment
CC2: Communication and Information
CC3: Risk Assessment
CC4: Monitoring Activities
CC5: Control Activities
CC6: Logical and Physical Access Controls
CC7: System Operations
CC8: Change Management
CC9: Risk Mitigation
Using Vanta’s initial assessment report as a to-do list, address each of the applicable controls in the other Trust Services Criteria that you identified in your initial framework, but that you have not yet implemented.
Using Vanta’s initial assessment report, draft security policies and protocols that adhere to the standards outlined in SOC 2.
Vanta’s tool includes thorough and user-friendly templates to make this simpler and save time for your team.
Run Vanta’s automated compliance software again to determine if you have met all the necessary criteria and controls for your SOC 2 report and to document your compliance with these controls.
Complete a SOC 2 report audit
Select and hire an auditor affiliated with the American Institute of Certified Public Accountants (AICPA), the organization that developed and supports SOC 2.
Complete a readiness assessment with this auditor to determine if you have met the minimum standards to undergo a full audit.
If your readiness assessment indicates that there are SOC 2 controls you need to address before your audit, complete these requirements. However, if you have automated compliance software to guide your preparations and your SOC 2 compliance, this is unlikely.
Undergo a full audit with your SOC 2 report auditor. This may involve weeks or longer of working with your auditor to provide the documentation they need. Vanta simplifies your audit, however, by compiling your compliance evidence and documentation into one platform your auditor can access directly.
When you pass your audit, the auditor will present you with your SOC 2 report to document and verify your compliance.
Maintain your SOC 2 compliance annually
Establish a system or protocol to regularly monitor your SOC 2 compliance and identify any breaches of your compliance, as this can happen with system updates and changes.
Promptly address any gaps in your compliance that arise, rather than waiting until your next audit.
Undergo a SOC 2 re-certification audit each year with your chosen SOC 2 auditor to renew your certification.
