Cyberattacks keep increasing: one intrusion every 39 seconds (WatchGuard source) worldwide. For a company, every outage or security breach means financial losses, slower productivity and loss of customer trust.

A simple traditional firewall is no longer enough. You need a solution that blocks threats while ensuring smooth, uninterrupted connectivity.

That is exactly what SASYX does, the Next Gen Firewall specially designed for modern SD-WAN networks.

Unlike traditional firewalls, which simply filter incoming and outgoing connections, a Next Gen Firewall (NGFW) combines:

  • Deep packet inspection (Deep Packet Inspection).
  • Real-time intrusion detection and prevention.
  • The integration of advanced network features such as Multi Gateway SD-WAN.
  • Smart, centralised management of security policies.

The result: overall protection, but also network agility that meets the current needs of multi-site companies.

Companies no longer operate from a single site. They expand internationally, collaborate with remote teams, host applications in the cloud and must ensure a constant connection quality.
Yet multiplying Internet lines and managing their security often leads to:

  • High costs.
  • Increased network management complexity.
  • Uneven performance across sites.

This is precisely what SASYX solves thanks to its native integration of SD-WAN and Multi Gateway.

Imagine being able to:

  • Automatically optimise your network connections by choosing the best available route.
  • Balance the load across several Internet links (fibre, ADSL, 4G/5G).
  • Guarantee service continuity even if a connection goes down.
  • Reduce your costs by smartly using several providers.

That is exactly what SASYX’s Multi Gateway allows. This feature, derived from SD-WAN technologies, turns your network into a flexible, smart and resilient system.

1. Continuous connectivity, even in case of failure

Thanks to Multi Gateway (SD-WAN), SASYX automatically chooses the best available connection. If a line goes down, your teams don’t even notice: work continues without interruption.

2. Reduced costs, without compromising performance

By smartly using several Internet providers, you avoid the extra costs linked to a single dependency. The result: a higher-performing network at lower cost.

3. Stronger security against current threats

Advanced inspection, proactive detection and immediate blocking: SASYX protects your sensitive data and your users against the most sophisticated attacks.

4. Centralised and simple management

With a single interface, you manage all your connections and security policies in a few clicks. No more complex configurations and wasted hours.

Unlike other solutions on the market, SASYX was designed from the ground up for multi-site SD-WAN environments.
Where some competitors add SD-WAN as an option, SASYX integrates it at the very core of its architecture.
The result: better resilience, unrivalled ease of management and an optimised user experience

Too often, companies have had to choose between maximum security and network performance. SASYX changes the game by integrating both dimensions in a single tool:

  • Proactive protection against cyberattacks.
  • Smooth, fast, optimised network thanks to SD-WAN.

With SASYX, you sacrifice nothing: you gain in security, flexibility and productivity.

Your network is the beating heart of your company. Protecting it while making it more efficient is today an imperative.
By choosing SASYX, you opt for:

  • Advanced security worthy of a Next Gen Firewall.
  • Optimised connectivity thanks to Multi Gateway (SD-WAN).
  • Simplified management of your multi-site networks.
