When business owners hear “SD-WAN uses the internet,” the first question is usually:
“Is it secure enough for us?”
The answer? Yes — when done right, SD-WAN is more secure than many traditional WAN setups.
Let’s break down exactly why.
1. End-to-End Encryption
Every packet of data between your offices, cloud services, or remote workers is encrypted using IPsec or similar protocols.
Even if the data travels over public internet lines, it’s protected — just like a secure VPN tunnel, but built into the SD-WAN fabric.
At Connect2, we configure this encryption as standard on all SD-WAN deployments.
2. Integrated Firewall & Threat Protection
Many SD-WAN solutions now include next-gen firewall features:
-
Deep packet inspection
-
Intrusion prevention
-
Web filtering
-
Malware scanning
Even if you already have a firewall, SD-WAN can act as a first line of defence and route sensitive traffic through secure paths.
3. Smart Segmentation of Traffic
Traditional networks often rely on flat, open architectures. SD-WAN enables micro-segmentation — meaning your VoIP, payment terminals, CCTV, and staff Wi-Fi can each be isolated by policy.
So if one segment is compromised (e.g. a guest Wi-Fi device), the rest of your network stays untouched.
This is a game-changer for:
-
Retailers with public networks
-
Healthcare practices handling patient data
-
Financial firms needing strict compliance
️ 4. Visibility = Control
You can’t protect what you can’t see.
SD-WAN dashboards show live traffic flows, suspicious behaviour, and bandwidth hogs. Connect2’s managed service includes 24/7 monitoring from our UK-based NOC (Network Operations Centre), so threats are flagged and resolved before they affect your business.
5. Works with Your Existing Security Stack
Already using third-party firewalls or cloud-based threat detection tools? No problem. SD-WAN can route traffic through those systems or integrate with them via APIs.
That flexibility means we can customise your setup — not rip and replace it.
