Modern Workplaces Demand a New Meaning for “Site” in Network Security

The Problem with the Traditional Idea of a Site

For a long time, the concept of a “site” in networking and security was synonymous with a physical office. This included:

• a headquarters building
• a branch office
• a campus connected to the corporate network

This traditional model was built on several assumptions:

• employees primarily worked from offices
• security measures were enforced at the boundaries of the network
• policies could reliably depend on the origin of network traffic

However, these assumptions no longer reflect the reality of modern work environments.

Today, employees:

• work from home, coffee shops, hotels, and other temporary locations
• move between locations multiple times throughout the day
• use GenAI tools continuously, regardless of their physical location

When security policies are tightly coupled to physical locations, several issues arise:

• the same user may receive different security policies during the same day
• remote access exceptions accumulate
• GenAI controls become inconsistent and difficult to audit
• security posture can drift unpredictably

AI>Secure addresses these challenges by redefining what “site” means in its platform.

What a Site Means in AI>Secure

In AI>Secure, a site serves as a policy anchor rather than merely representing a physical building. A site may represent:

• a physical office location
• a logical home location
• a functional or organizational boundary
• a security boundary that is not tied to geography

This flexibility allows organizations to choose whether policies should:

• follow the user
• follow the location
• or implement a hybrid of both approaches

Two Ways to Use Sites (Both Supported)

AI>Secure supports both models simultaneously. Customers may choose to use one, the other, or a combination of both.

Logical Sites: Policies Follow the User

In this model:

• a site represents a logical home location
• policies remain consistent as the user moves between locations
• physical location does not affect policy enforcement

Example:

• a user belongs to the “San Jose Engineering” site
• the user works from home in the morning
• later works from a coffee shop
• then visits another company office

Throughout the day:

• the same GenAI policies apply
• the same data protection rules apply
• the same inspection and enforcement behaviors apply

This model is well-suited for:

• hybrid and remote-first workforces
• consistent GenAI security
• predictable auditing and compliance

Physical Sites: Policies Follow the Location

In this model:

• a site represents where network traffic originates
• policies change based on physical or network location

Example:

• working from HQ applies HQ policies
• working from a branch applies branch policies
• working remotely applies remote policies

This approach is particularly useful when:

• regional regulations differ
• trust levels vary by location
• existing operational models must be maintained

Logical Sites Also Work with IPsec-Based Transparent Proxy

A common misconception is that logical sites are only compatible with forward proxy setups. In AI>Secure, logical sites function with both:

• forward proxy deployments
• IPsec-based transparent proxy deployments

Site determination is explicit and driven by configuration, rather than being inferred.

How Site Determination Works with Forward Proxy

When users access AI>Secure via a forward proxy:

• each logical site is mapped to a specific proxy port
• employee devices are provisioned with the relevant proxy domain and port
• traffic always lands on the same port, regardless of the user’s location

As a result:

• the port maps to a site
• the site is associated with a security profile
• the same policies are enforced everywhere

Even though users connect to the nearest AI>Secure point of presence (POP) for performance, AI>Secure ensures site mappings, security profiles, and policy configurations are available across all POPs configured for that site.

How Site Determination Works with IPsec-Based Transparent Proxy

With IPsec-based deployments:

• multiple dedicated VPN tunnels can be established
• each tunnel is explicitly associated with a site
• traffic arriving on a tunnel determines the site

Important details:

• a physical office can have multiple VPN tunnels
• one tunnel can represent a logical home site
• other tunnels can represent access from other offices or mobile users
• logical sites are preserved even in transparent proxy mode

This means:

• a site does not have to equal a building
• a site represents policy identity
• physical and logical models can coexist

Additional Scenarios Enabled by Logical Sites

When a site is treated as a policy identity, new use cases become straightforward.

Role-based sites:

• engineering
• finance
• legal
• executives

Each role can have distinct GenAI access, inspection depth, and data protection rules.

Contractor and partner isolation:

• contractors assigned to dedicated logical sites
• tighter controls without the need for separate networks

Temporary or project-based sites:

• M&A activity
• investigations
• special R&D projects
• sites can be created and removed cleanly

Regulatory segmentation:

• GDPR-covered users
• HIPAA-related workflows
• export-controlled teams
• segmentation enforced without redesigning network topology

Why This Matters for GenAI Security

GenAI usage is:

• user-driven
• location-independent
• continuous throughout the day

Security controls that are tied exclusively to physical locations no longer match the reality of modern work. By treating site as a flexible policy abstraction, AI>Secure supports:

• consistent GenAI guardrails
• predictable enforcement
• reduced policy drift
• improved auditability

Summary

In AI>Secure:

• a site is a policy anchor, not just a physical office
• sites can be logical or physical
• logical sites work with both forward proxy and IPsec transparent proxy models
• policies can follow users, locations, or both
• enforcement remains consistent across global points of presence

This approach aligns security with the realities of modern work and GenAI usage.
