Web access used to be simple. Employees sat inside the office network, traffic flowed through a firewall, and blocking a few risky websites was enough to stay safe. That model no longer holds up.
Employees now access the web from multiple networks and devices, including home Wi-Fi, public connections, and cloud-based applications. In many cases, web traffic never passes through a single office gateway.
While both traditional web filters and secure web gateways are used to manage web access, they are built for different environments and operate in different ways. This shift makes choosing the best secure web gateway solution critical, one that can enforce consistent policies across endpoints, provide visibility into cloud app usage, and protect users no matter where they connect from.
What is the difference between Secure Web Gateways and Traditional Web Filters?
Traditional web filters were built around network-based setups, while Secure Web Gateways (SWGs) are designed to work at the device or endpoint level. The differences between the two become clear in how they handle modern web traffic. Here are the key differences between the two:
Traditional Web Filters
Traditional web filters work at the network level. Web traffic passes through a shared control point, such as a firewall or proxy, and access is allowed or blocked based on predefined categories, domains, or keywords.
This model tends to work best under certain conditions.
- Devices stay inside the office network
- Users connect through a fixed gateway
- Applications are mostly on-prem
But the moment users step outside that environment, coverage starts to break. Remote users often bypass filters entirely. Mobile devices behave inconsistently. Cloud apps don’t always map cleanly to category-based filtering.
Traditional filters also tend to be coarse-grained. Policies are often applied at the network level rather than the user or device level. That makes flexibility harder as organizations grow.
Secure Web Gateways (SWGs)
Secure Web Gateways (SWGs) like Scalefusion Veltar apply web access controls at the device level. Protection stays active even when users connect from outside corporate networks.
Common characteristics:
- Policies are applied per device rather than per network
- Web access remains protected across home Wi-Fi, public networks, and mobile connections
- Rules can vary based on user, device, or assigned role
Secure web gateways inspect web traffic in real time and track cloud application usage. These capabilities are used to control access to risky or non-compliant websites during regular use.
Choosing between Secure Web Gateways and Traditional Web Filters
Traditional web filters are tied to network-based traffic paths. Web access is controlled through a central gateway, and filtering rules are applied at that point.
Web traffic can originate from different networks and devices. It does not always pass through a single gateway.
Secure web gateways apply web access policies at the device level. Controls remain active across different locations and connection types, regardless of the network being used.
Secure web gateways are generally considered the more effective and future-ready option when web access spans multiple networks and cloud-based applications. Network-based filters can still be used in smaller on-prem setups, but they fit fewer modern access patterns.

Key features to consider when choosing a Secure Web Gateway solution
- UEM-native dashboard: Manage web security from the same console used for device management. Apply policies, view logs, and track blocked activity without switching tools.
- Policy enforcement at the device: Rules are enforced directly on the endpoint, not the network. This keeps protection active on any Wi-Fi or location without traffic rerouting.
- Granular policy enforcement: Apply different web access rules based on user, device, or role. Teams get the access they need without unnecessary restrictions.
- Real-time web content filtering: Block unsafe, non-compliant, or unproductive websites instantly. Categories and custom lists update in real time to reduce exposure.
- Custom URL filtering: Allow or block specific URLs within broader categories. This gives flexibility without opening access wider than needed.
- Cloud app restrictions: Control access to cloud apps by restricting personal domains. Allow only approved corporate accounts to reduce data leakage risk.
Choose the right Secure Web Gateway solution for your business
In 2026, secure web gateways are no longer just about blocking a few websites. They are a core part of endpoint security in cloud-first, distributed work environments.
Organizations vary in size, device mix, and compliance needs. Laptops, mobile devices, and BYOD environments often require policies that stay consistent across locations..
Remote and hybrid work also changes the equation. When users work from multiple networks, security must follow the device, not the office. Budget and operational complexity play a role too. Some teams need lightweight controls, while others require deeper visibility and tighter enforcement.
For most modern teams, secure web gateways are now essential. Choosing a solution like Scalefusion Veltar that is built on a UEM platform helps reduce tool sprawl, improves visibility, and keeps web security aligned with device management.
Traditional web filters addressed older, network-bound setups. Secure web gateways are built for how work happens today.
