Security
VPN: Limited, perimeter-based security.
SASE: Comprehensive security with Zero Trust-based access.
Use Cases
VPN: Traditional approach, suitable for internal networks
SASE: Designed for distributed businesses and mobile users.
Remote Work Performance
VPN: Slow connections and bottlenecks.
SASE: Cloud-optimized routes, low latency from anywhere.
Management and Visibility
VPN: Disconnected tools, limited visibility.
SASE: Centralized control, real-time dynamic policies.
En un mundo donde el teletrabajo, las plataformas en la nube y las ciberamenazas evolucionan a diario, las empresas se enfrentan a una pregunta crucial:
¿Deberían seguir con las VPN tradicionales o migrar a entornos modernos como SASE?
Este blog ofrece una comparación clara y accesible para ayudarle a tomar una decisión informada, sin necesidad de conocimientos técnicos avanzados.
¿Qué es una VPN? ¿Y qué es SASE?
🔹 VPN (Red Privada Virtual): una tecnología que crea una conexión segura entre el dispositivo del usuario y la red corporativa a través de internet. Originalmente, se diseñó para que los empleados remotos pudieran acceder a los recursos internos de la empresa como si estuvieran en la oficina.
Sin embargo, con la adopción de la nube y la distribución de personal, las VPN presentan limitaciones de escalabilidad y seguridad.
🔹 SASE (Secure Access Service Edge): un enfoque moderno que fusiona las redes (como SD-WAN) y la seguridad (como firewalls, ZTNA y filtrado DNS) en una solución unificada y nativa de la nube.
Permite un acceso seguro, rápido y controlado a aplicaciones y datos desde cualquier lugar, sin necesidad de infraestructura física adicional.
Security
Traditional VPNs were built for centralized, internal networks. Today, data resides in multiple clouds and users connect from anywhere. Perimeter-based security is no longer enough.
SASE (Secure Access Service Edge) merges security and connectivity into one cloud-native platform. It uses Zero Trust Network Access (ZTNA), real-time traffic inspection, and cloud-managed control to offer adaptive, scalable protection.
According to Gartner, 60% of enterprises will adopt SASE in some form by 2025.
Requires extra tools for layered security and allows flat, unrestricted access.
Offers segmented access, cloud firewalls, and identity-based contextual control.
Real-life scenarios: companies with and without SASE
Here are three business scenarios to illustrate how each model performs:
Uses VPN to connect offices and remote workers, but struggles with slow speeds, low visibility, and increased vulnerabilities.
Moving more services to the cloud and needs flexible security. Piloting SASE at critical sites.
Operates entirely on cloud infrastructure, enjoys real-time visibility, reduced risk, and secure access from anywhere.
Performance for remote work
VPNs route all traffic through a central server, causing bottlenecks—especially for real-time tools like Zoom or Microsoft Teams.
SASE optimizes traffic delivery from geographically distributed points, reducing latency and improving performance.
🔹Slow speeds during peak hours.
🔹Unstable connections from remote areas.
🔹Overloaded VPN servers.
🔹Low latency from anywhere.
🔹Location-based traffic routing.
🔹Better experience for mobile users.
Management and visibility
VPNs lack centralized visibility. Managing multiple tools increases operational complexity and leaves security gaps. SASE integrates all network and security controls into one dashboard, with dynamic, automated policies.
🔹Siloed policy management.
🔹Difficult real-time traffic monitoring.
🔹No native tool integration.
🔹Full user and traffic visibility.
🔹 Policy automation.
🔹Full network and security integration.

asked questions (FAQ)
No. Many companies use both models during a transition. You can start by migrating your most vulnerable areas.
Not at all. SMBs benefit greatly, especially if they use cloud services or have remote teams.
Usually not. SASE is cloud-based and adapts to your current infrastructure.
Very secure. It uses identity-based access, continuous inspection, and Zero Trust to minimize risks.
SASE is ideal. It’s designed for distributed organizations and provides consistent protection and access regardless of location.
Yes. SASE integrates with SaaS platforms, cloud services, and most enterprise tools.
The secret of change is to focus all your energy not on fighting the old, but on building the new.
