Secure Remote Access for Texas SMBs: Beyond the Legacy VPN in 2026

Traditional VPNs grant network-level access: authenticate once, then reach everything the network routing allows. That violates least privilege and segmentation at the same time. VPN appliances have also been a top breach vector — a string of critical vulnerabilities in popular VPN gateways gave attackers direct entry. The model assumes "inside the VPN = trusted," which is exactly the assumption Zero Trust rejects.

ZTNA replaces "connect to the network" with "connect to a specific application." Access decisions are made per-request based on verified identity, device compliance, and context — and the user can only reach the specific apps they are authorized for, never the broader network. Even if a device is compromised, the blast radius is limited to a handful of authorized apps instead of the whole environment. ZTNA is typically delivered as part of SASE.

For admin access and legacy apps, never expose RDP directly to the internet — it is relentlessly scanned and brute-forced. Instead:

• Jump host / privileged access workstation — admins connect through a hardened, monitored gateway, never directly
• Just-in-time access — the RDP port opens only for an approved, time-boxed window
• Phishing-resistant MFA on every remote session
• Session recording for privileged access

Remote access should require a known, compliant device — not just a correct password. Conditional Access tied to Intune compliance ensures a personal, unpatched, or compromised device cannot reach corporate resources even with valid credentials.

1. Inventory what remote users actually need to reach
2. Pilot ZTNA for a handful of apps alongside the existing VPN
3. Migrate app by app, shrinking VPN scope as you go
4. Move admin access behind a jump host with JIT + MFA
5. Decommission the flat VPN once apps are migrated
6. Enforce device compliance throughout

Stop exposing RDP, require compliant devices for all remote access, and pilot ZTNA for your most-used apps. See network technology services, cybersecurity services, and the ZTNA migration guide.
