👉 Secure Remote Access for Swiss SMEs: VPN and Zero Trust Explained

Resources, IT Security
Page content

Remote and hybrid work are now standard for many Swiss SMEs.
As a result, secure remote access has become a foundational requirement for protecting business systems and sensitive data.

This resource explains how Swiss SMEs can provide secure remote access, compares common approaches, and outlines selection criteria aligned with Swiss data protection requirements.

What Is Secure Remote Access?

Secure remote access allows employees and partners to connect to internal systems and cloud services safely from outside the office.

A secure solution ensures:

  • encrypted connections
  • controlled access based on user and device
  • visibility into remote activity

Without proper controls, remote access becomes one of the most common attack vectors.

Common Remote Access Risks for Swiss SMEs

Swiss SMEs typically face the following risks:

  • Unsecured home networks
    Home routers and Wi-Fi networks often lack enterprise-grade security.

  • Stolen or weak credentials
    Password reuse and phishing attacks lead to account compromise.

  • Overly broad network access
    Traditional VPNs may grant more access than necessary.

  • Lack of visibility
    IT teams struggle to monitor who accesses what and from where.

Tip: Secure remote access should be treated as a security control, not just a connectivity feature.

Secure Remote Access Approaches

Swiss SMEs usually choose between two main approaches: VPN-based access and Zero Trust Network Access (ZTNA).

VPN (Virtual Private Network)

How It Works
A VPN creates an encrypted tunnel between the user’s device and the company network.

Typical Use Cases

  • Remote employees accessing internal systems
  • Small IT teams needing simple deployment
  • Legacy applications hosted on internal networks

Advantages

  • Well understood and widely supported
  • Relatively simple to deploy
  • Works with most applications

Limitations

  • Often grants broad network access
  • Limited visibility into user behavior
  • Scaling and management can become complex

Zero Trust Network Access (ZTNA)

How It Works
ZTNA grants access based on user identity, device status, and context rather than network location.

Typical Use Cases

  • Cloud-first environments
  • Distributed teams and partners
  • Organizations adopting Zero Trust principles

Advantages

  • Access is limited to specific applications
  • Better visibility and control
  • Reduced attack surface

Limitations

  • Requires more planning
  • May not support all legacy systems

VPN vs Zero Trust: Which Is Right for Swiss SMEs?

The right choice depends on company size, infrastructure, and risk tolerance.

Criteria VPN Zero Trust
Ease of deployment High Medium
Access granularity Low High
Cloud compatibility Medium High
Scalability Medium High
Security maturity required Low Medium

Many Swiss SMEs start with a VPN and gradually move toward Zero Trust as their environment evolves.

Selection Criteria for Swiss SMEs

When choosing a secure remote access solution, Swiss SMEs should evaluate:

  • Encryption standards
    Support for modern protocols and strong encryption.

  • Identity integration
    Compatibility with identity providers and multi-factor authentication.

  • Device security checks
    Ability to restrict access based on device status.

  • Compliance support
    Alignment with the Swiss Data Protection Act (DSG).

  • Operational effort
    Manageability without a dedicated security team.

Secure Remote Access and Swiss Compliance (DSG)

Remote access solutions often handle personal and business-critical data.

Under the Swiss Data Protection Act (DSG), SMEs must:

  • protect data confidentiality
  • control and document access
  • ensure appropriate technical and organizational measures

Secure remote access plays a direct role in meeting these obligations.

How This Resource Fits into a Security Strategy

Secure remote access should not operate in isolation.

It works best when combined with:

  • strong identity and authentication controls
  • endpoint security and device management
  • network segmentation and monitoring

Together, these controls form the foundation of a Zero Trust approach.

What Comes Next

Future resources and reviews will examine specific VPN and Zero Trust solutions suitable for Swiss SMEs, focusing on security, usability, and compliance.

This ensures decisions are based on real-world SME requirements rather than vendor marketing.

Conclusion

Secure remote access is no longer optional for Swiss SMEs.
By understanding the differences between VPN and Zero Trust approaches and applying clear selection criteria, businesses can enable remote work while significantly reducing security risks.

A well-chosen remote access solution strengthens overall security and supports long-term business resilience.
