VPN solutions

Secure access to your corporate network from the road or home office—either with Sophos Connect (SSL-VPN, seamlessly integrated into your Sophos firewall) or OPNsense with IPsec (open standard, vendor-independent). We implement both options consistently according to zero-trust principles: device profiles instead of blanket network access, granular permissions, and continuous verification instead of one-time login.
SEGMENTED & CONTROLLED

Network segmentation

Thoughtful separation of network areas limits the spread of attacks and protects critical systems. We also securely implement cross-vendor site-to-site connections—even a FritzBox can be reliably connected to professional firewalls using its available security protocols. Redundant connections via load balancing and modern SD-WAN methods ensure failover protection.
30 years of expertise and comprehensive know-how

Networks that contain attacks instead of enabling them

A single flat network is a single large attack surface. We segment your network so incidents cannot spread unchecked.

Was ist der Unterschied zwischen VPN und Netzwerksegmentierung?

Ein VPN verschlüsselt die Verbindung von außen in Ihr Netzwerk – etwa aus dem Homeoffice. Netzwerksegmentierung sorgt dafür, dass innerhalb Ihres Netzwerks nicht jedes Gerät mit jedem anderen kommunizieren kann. Beides zusammen verhindert, dass ein einzelner kompromittierter Zugang zum kompletten Netzwerkausfall führt.

Können mehrere Standorte sicher miteinander vernetzt werden?

Ja. Über Site-to-Site-VPN-Verbindungen lassen sich mehrere Standorte verschlüsselt und zuverlässig miteinander verbinden – so, als wären sie ein einziges Netzwerk, ohne dabei die Sicherheit zu gefährden.

Wie schnell wird ein Angriff im Netzwerk erkannt?

Unsere IDS/IPS-Systeme überwachen den Datenverkehr kontinuierlich in Echtzeit. Verdächtige Muster werden automatisch erkannt und blockiert, unser Team wird umgehend benachrichtigt – meist bevor ein Vorfall überhaupt spürbare Auswirkungen hat.
