Your VPN Connects Users to a Network.
Cisco Secure Access ZTNA Connects Them to the Application.
VPN Was Built to Connect You to the Network. ZTNA Is Built to Connect You to the Application.
One of the biggest differences between traditional VPN and Zero Trust Network Access is what the user actually receives after authentication. A traditional remote-access VPN commonly creates a network connection that makes the remote endpoint behave more like an extension of the private network. Depending on the architecture, this can provide access to a broad range of internal resources — far more than most users actually need.
That model worked well when employees primarily worked from corporate offices and most business applications lived inside a company data center. Modern businesses operate differently:
- Employees work from multiple locations.
- Applications are distributed between cloud and on-premises environments.
- Companies use Microsoft 365, SaaS, and cloud-hosted applications.
- Contractors and third parties sometimes require limited access.
- Employees use laptops, mobile devices, and other endpoints.
- Security teams need stronger identity and device controls.
Instead of asking, “How do we put this employee onto our network?”, a Zero Trust architecture asks:
“Who is this user, what device are they using, what application are they requesting, and should they be allowed to access it right now?”
What’s Exposed When VPN Access Is Too Broad
When remote access is granted at the network level instead of the application level, every one of these becomes a bigger risk than it needs to be.
What Is Cisco Secure Access?
Cisco Secure Access is a cloud-delivered Security Service Edge (SSE) platform designed to provide secure access to private applications, internet resources, and cloud services while applying Zero Trust principles. Cisco describes Secure Access as a solution that provides secure access from users and devices to applications from virtually anywhere, combining Zero Trust Network Access, secure web access, and other security controls through a centralized, cloud-managed platform.
For businesses, this means remote access no longer has to be treated simply as a VPN connection. Access policies can instead be built around identity, device posture, application requirements, and security context.
Why Businesses Are Moving Toward Zero Trust Network Access
Zero Trust Network Access is built on the principle that access should be explicitly verified and limited to what a user actually needs — not automatically granted at the network level because a password was correct.
Reduce the Attack Surface
If an employee only needs access to one internal application, there’s little reason to expose the rest of the internal network to that endpoint. ZTNA can restrict access to only the applications a user is authorized to use.
Limit Lateral Movement
Application-specific access reduces the opportunity for a compromised endpoint to reach additional internal resources it was never meant to touch.
Improve Remote-Worker Security
A modern access architecture should account for users working from homes, hotels, customer locations, airports, and coworking spaces — networks the business does not control.
Support Contractors and Third Parties
Contractors, vendors, and partners may require access to one or two applications without needing access to an entire corporate network. ZTNA makes least-privilege access much easier to design.
Simplify Security Management
Cisco Secure Access provides centralized policy management for private and internet applications, allowing organizations to manage security policies from a single cloud-based platform.
Traditional VPN vs. Cisco Secure Access ZTNA
The goal isn’t simply replacing a VPN client with another application — it’s shifting the security model from network trust to identity and application-based access.
| Traditional VPN | Cisco Secure Access ZTNA |
|---|---|
| Network-oriented access | Application-oriented access |
| User connects to a network or segment | User connects to approved applications only |
| Can provide broader network visibility | Applications can remain hidden from unauthorized users |
| Primarily dependent on VPN authentication | Identity, device, and contextual access policies |
| Potentially larger lateral movement opportunity | Least-privilege application access |
| Often requires VPN infrastructure and tunnel management | Cloud-delivered access with centralized policy management |
Cisco Secure Access Is More Than a VPN Replacement
Cisco Secure Access isn’t simply a product designed to eliminate every VPN connection. Some legacy applications and network services still require traditional network connectivity, so Cisco Secure Access also supports VPN-as-a-Service (VPNaaS) alongside ZTNA — giving businesses a practical migration path:
- Identify applications that can use ZTNA.
- Move appropriate applications to least-privilege access.
- Continue supporting legacy applications that require VPN connectivity.
- Gradually reduce dependency on traditional remote-access infrastructure.
- Centralize security and access policies where practical.
In other words, businesses don’t have to make a risky “VPN off, ZTNA on” change overnight. DistrictConnects designs a phased migration based on the applications, users, network architecture, and security requirements of your organization.
Our Zero Trust Deployment Process
Six steps that move a business from broad, network-level VPN access to identity-aware, application-specific Zero Trust access.
Assess the Current Environment
We review your existing firewall, VPN configuration, identity provider, endpoints, internal applications, DNS, network segmentation, and remote-access requirements.
Identify Users and Applications
We determine which employees, contractors, and other users need access — and exactly which applications they need.
Classify Applications
Applications are evaluated to determine whether they’re suitable for ZTNA, require VPN-based connectivity, or should be redesigned or retired.
Build Identity-Based Policies
Access policies are built around user identity, application, device posture, and other contextual security requirements.
Deploy and Test
We deploy the required Cisco Secure Access components, configure access policies, and test the user experience before moving production users.
Monitor and Optimize
After deployment, access policies are reviewed regularly as part of our managed IT services. Security architecture is never a set-it-and-forget-it project.
Where ZTNA Fits Into Your Security Stack
Cisco Secure Access ZTNA is designed to work alongside the identity, endpoint, and network tools your business already relies on.
Who Should Consider Cisco Secure Access ZTNA
ZTNA can be particularly valuable for organizations with the following characteristics.
What About Microsoft 365, Entra ID, and Identity Security?
Modern remote access can’t be separated from identity. If a business is already using Microsoft 365 and Microsoft Entra ID, identity should be a major part of the access architecture. DistrictConnects evaluates how identity, authentication, endpoint security, and application access work together, rather than treating the VPN or ZTNA platform as an isolated product — especially important for organizations with employees who work remotely or use multiple devices.
Our Goal Is Simple
Give your employees secure access to the resources they need — without unnecessarily exposing the rest of your network.
Traditional VPN vs. Cisco Secure Access ZTNA: Which Is Right for Your Business?
The answer isn’t always “replace the VPN.” Some organizations will benefit from a full ZTNA migration. Others may need a hybrid architecture where ZTNA handles modern applications while VPNaaS continues supporting legacy systems. The right architecture depends on your applications, identity platform, endpoints, firewall infrastructure, compliance requirements, and business operations — which is why a professional assessment should happen before making the decision.
Is Your VPN Still the Right Remote-Access Solution?
DistrictConnects assesses, redesigns, and modernizes remote-access and cybersecurity infrastructure for businesses across Northern Virginia, DC, and Maryland. We’ll review your current VPN, firewall, identity, and application environment and tell you whether ZTNA, a hybrid architecture, or your existing solution is the right fit.

Frequently Asked Questions
Can Cisco Secure Access Replace a Traditional VPN?
In many use cases, yes. Cisco Secure Access provides Zero Trust Network Access that can grant application-specific access instead of placing a remote user onto a broader corporate network. Some legacy applications may still require VPN connectivity, which is why Cisco Secure Access also supports VPN-as-a-Service.
Is ZTNA More Secure Than a Traditional VPN?
ZTNA can provide a more granular security model because access can be limited to specific applications based on identity and context rather than providing broader network access. The actual security outcome depends on proper identity, endpoint, application, and policy configuration.
Does ZTNA Eliminate the Need for a Firewall?
No. ZTNA and firewalls solve different security problems and work together. A complete security architecture may include firewalls, endpoint protection, identity security, network segmentation, secure web access, and Zero Trust application access.
Can Contractors Use Cisco Secure Access?
Yes. Depending on the architecture, organizations can use client-based or clientless access models to provide limited access to approved applications for contractors, partners, and other users.
Does Cisco Secure Access Work With On-Premises Applications?
Yes. Cisco Secure Access can provide Zero Trust access to private applications hosted within business environments while enforcing access policies through the Secure Access architecture.
Should a Small Business Move From VPN to ZTNA?
It depends on the business. Users, applications, endpoints, identity infrastructure, security requirements, and existing network design should all be evaluated before deciding. DistrictConnects can perform an assessment and recommend a practical migration strategy.
