Here's a summary of the key settings to configure:

Managing network and access control is a crucial aspect of implementing Cloudflare Zero Trust. Typically, businesses start with a simple network topology but as they grow, their network becomes increasingly complex. This complexity can lead to difficulties in managing connected VPCs, external connections, and security groups.

To simplify the corporate network, businesses should review connectivity options and explore strategies to build a functionally complex, fundamentally secure network. This may involve setting up identity-aware or service-aware site-to-site connectivity, or using unidirectional connector models to provide secure access in either direction.

Cloudflare Access can integrate with multiple identity providers simultaneously, allowing for granular capabilities to 'force' some user access to authenticate in specific ways. This can be particularly helpful when managing third-party access, as it enables administrators to create functional identities and integrations for third parties, streamlining their administrative management activities.

Here are some key considerations for managing network and access control:

Having multiple endpoint agents on a single user machine can introduce network routing complexity and conflicts, especially if private networks overlap across different businesses.

Contractor groups often have multiple endpoint agents connected to a single user machine, making it essential to consider tightly-scoped routing controls to ensure limited access to your network.

To ensure a simple process for third-party access, you should check if your Zero Trust vendor supports multiple profiles for endpoint agent deployment.

If your Zero Trust vendor can support multiple profiles, contractor users will have limited access to your network, reducing the risk of conflicts with other agents on the device.

Consider building functional identities and integrations for third parties if their access is materially the same as corporate user access.

New policies may not be needed if everything can be audited and differentiated, streamlining your administrative management activities.

Here are some key factors to consider when evaluating third-party access:

Network interconnection is a crucial aspect of network and access control. As businesses grow, their network topology becomes increasingly complex, with multiple VPCs and external connections to physical locations.

Typically, businesses start by managing connected VPCs in AWS or GCP, but this can quickly become overwhelming. Most businesses find themselves with multiple internal networks, each with distinct policies and operations.

Customer networks, partners, and multi-cloud environments are common extensions that require careful consideration. Simplifying the corporate network is essential to maintain security and efficiency.

As security groups for VPCs become complex, managing multiple internal networks becomes a significant challenge. This is where network interconnection strategies come into play, helping to build a functionally complex, fundamentally secure network.

Remote access for partners is a crucial aspect of network and access control. It allows partners to securely access your network and resources, while minimizing the risk of unauthorized access.

To establish remote access for partners, you'll need to consider the type of access they require. This may include contractors, vendors, or customers who need access to specific parts of your network or applications.

You should establish a separate identity and access management (IAM) system for partners, which can include multiple profiles for endpoint agent deployment. This will help you manage access and ensure that partners only have the necessary permissions to access your network and resources.

Here are some key considerations for remote access for partners:

By following these best practices, you can ensure that your partners have secure and controlled access to your network and resources.

Cloudflare Access can help provide scoped secure access for both web and network connectivity to your partners in a Zero Trust framework. It can integrate and use multiple identity providers simultaneously, and can have granular capabilities to 'force' some user access to authenticate in specific ways.

Here are some benefits of using Cloudflare Access for partner access:

By using Cloudflare Access, you can ensure that your partners have secure and controlled access to your network and resources, while minimizing the risk of unauthorized access.

Identity is at the core of every Zero Trust strategy, and most customer goals revolve around using a central source of identity to authenticate and log all actions taken by a user.

Using an SSO provider, like Google Workspace or Microsoft Entra Identity, can layer additional security controls like multi-factor authentication, which has been credited by Cloudflare as a major factor in stopping attempted breaches. Phishing-resistant MFA options like physical keys, local authenticators, and biometric authentication are also effective.

Identity is at the core of every Zero Trust strategy. Ultimately, most customer goals revolve around using a central source of identity to authenticate, validate, and log all actions taken by a user.

Coaching users to become accustomed to using multi-factor authentication is crucial. This can be done by implementing phishing-resistant MFA options like physical keys, local authenticators, and biometric authentication.

The type of identity provider you decide to use is less important than your implementation strategy. Cloudflare credits phishing-resistant MFA options as a major factor in stopping the attempted breach that affected Twilio and other SaaS companies in 2022.

A secure directory that allows for phishing-resistant authentication methods is essential. This directory should be designated as your source of truth to integrate with a Zero Trust vendor like Cloudflare.

The concept of Zero Trust access has traditionally been about user or machine access to internal or privileged resources, but vendors have started to blur the lines by offering secure web gateways as part of the same product.

Secure web gateways (SWG) and Zero Trust access (ZTNA) are now often discussed together, driven by vendors and analysts rather than security researchers.

The traditional castle-and-moat model of security has introduced complexity challenges, leading vendors to address the two primary functions a VPN serves: managing internet traffic and maintaining a unified view of threats.

Deploying a single agent to handle both corporate and internet traffic is a significant improvement over using multiple device agents for various security tooling.

This shift has improved security manageability for customers and simplified the buying and deployment process for startups.

Starting a Zero Trust security posture can be a daunting task, but having clear goals in mind can make all the difference. Many startups are encouraged to adopt a Zero Trust security posture by external sources such as investors, partners, vendors, risk analysts, or compliance officers.

Some common goals we hear from customers include making internal tooling easy for users to access securely, building security into the development pipeline, and adopting increased security without sacrificing user and work experience. These goals can be achieved by simplifying management of networks and application access, protecting data in SaaS applications and on the corporate network, and ensuring auditability.

It's also possible that your goals may be simpler or more tactical than this, such as adopting a modern remote access tool or securely connecting internal networks. Whatever your goal, it's crucial to start with a Zero Trust vendor that can help layer on additional security tooling and capabilities without exponentially increasing complexity or cost.

Here are some common goals and objectives that startups typically aim to achieve with Cloudflare:

Remember, goal-setting is also an important exercise for prioritization. By understanding the stack-rank of priorities over the next few months, you can save time spent in re-architecture discussions or unraveling technical or commercial decisions with vendors.

When integrating third-party access with Cloudflare Zero Trust, it's essential to consider the needs of your external users. To ensure a simple and manageable process, look for a Zero Trust vendor that supports multiple profiles for endpoint agent deployment.

This will allow you to tightly scope routing controls for contractor users, limiting their access to your network and reducing the risk of conflicts with other agents on the device.

One key factor is determining whether third-party access is materially different from corporate user access. If not, you can streamline your administrative management activities by building functional identities and integrations for third parties.

Here are some key considerations to keep in mind:

By considering these factors, you can ensure a seamless integration of third-party access with Cloudflare Zero Trust, while maintaining the security and control that your network requires.

Cloudflare tokens are based on the information received from your identity provider after a successful authentication event, which matches against custom policies for that application.

Each token contains all of the content that would be signed in a user's authentication event with their IdP, including their name, username, email, group membership, and whatever other values are present.

A unique tag is added to each token to indicate its relevance to a specific application.

Using Cloudflare tokens takes minimal additional work per-application and can be built into application creation workflows.

This approach eliminates the need for a complete OAUTH integration or SSO integration, providing a seamless user experience.

Cloudflare tokens can be used directly in your internal applications to validate requests and authorize access to internal tooling.

Your external users may need to deploy an endpoint agent used for Zero Trust deployment if network-level controls can't be established over a web browser.

Contractor groups often have multiple endpoint agents connected to a single user machine, which can introduce network routing complexity or conflicts if some of these private networks overlap across different businesses.

To ensure a simple, manageable process for ensuring third-party access, consider the following questions:

If third-party access is not materially different, you can streamline your administrative management activities by building functional identities and integrations for third parties. New policies may not necessarily need to be created, as long as everything can be audited and differentiated.

To set up a Cloudflare Zero Trust Tunnel, you'll need to create and configure a Cloudflare Tunnel, which securely connects your services to Cloudflare without exposing them to the public internet. This is done by storing the tunnel token securely in AWS Secrets Manager.

The Terraform resource will automatically check if the secret already exists, and if it does, it updates the secret; otherwise, it creates a new one. This ensures that your tunnel token is always secure and up-to-date.

To establish a secure tunnel connection, you'll need to define the configuration for the Cloudflare Tunnel itself, specifying details like the tunnel name, account ID, and associated routes service. This lays the groundwork for your CF-ZTNA.

Here are the key settings to configure for your Cloudflare Zero Trust Tunnel:

By following these steps, you'll be able to create a secure and private path between your server and apps, allowing you to expose services to the internet securely without opening ports or requiring a VPN.

Mesh connectivity is a networking concept that connects networks to assets or independent endpoints, such as end-user devices and IoT devices.

In a mesh networking model, you can create micro-tunnels between specific IP spaces, limiting communication between devices.

This approach massively reduces opportunities for lateral movement, as seen with IP address 10.2.3.4 being unable to reach sensitive data on a different 192.168.0.0/24 address.

However, mesh networking also increases complexity, requiring management of agents on each endpoint and discrete policies for each asset and connectivity path.

Cloudflare recommends a blend of traditional and mesh networking models for businesses of all sizes, as both models have their limitations.

This blended approach supports a wide range of use cases, including remote access to corporate networks and mesh connectivity between critical infrastructure.

Cloudflare products, such as WARP client and Cloudflare Tunnel, can help support discrete connectivity models while layering in unique identity concepts and supporting security and scalability needs.

A Cloudflare Zero Trust Tunnel is a secure way to connect your private servers, apps, or networks to the internet without opening any ports in the firewall.

It's a safe, private path between the server and apps, allowing us to expose services to the internet securely.

The server makes an outbound, secure connection to Cloudflare, which safely manages who can access the server, adding security features like identity checks, policies, and encryption.

This approach is risk-free, as it doesn't let people reach into the server directly, which can be a security concern.

Cloudflare Tunnel creates a secure connection between the server and Cloudflare, which then determines who can access the server, making it a highly secure option.
