Replace your VPN and your firewall with zero trust access.
Spirex ZTNA grants per-application access verified by identity. A lightweight connector in your network replaces the VPN concentrator, closes inbound firewall ports, and makes your private apps invisible on the public internet.
VPN grants access to your network. That's the problem.
VPN was built for a world where your applications lived in a single datacenter and your users sat in an office. It grants broad network access rather than specific application access, and that gap is where the risk lives.
Once connected, users can reach far more than they need. A single compromised credential can mean lateral movement across the entire network segment, not just one app.
VPN concentrators sit on the public internet with inbound ports open. Every exposed port is an attack surface your team has to defend, patch, and monitor around the clock.
VPN has no visibility into what authenticated users do inside applications. The moment someone is through the gate, the session is a blind spot: no DLP, no phishing detection, no audit trail.
Firewall and VPN concentrator hardware requires refresh cycles every 3–5 years. capital expenditure, procurement delays, maintenance contracts, and the same vulnerabilities rebuilt in new hardware.
A connector in your network. No inbound ports. Apps off the internet.
The Spirex connector is a lightweight service you deploy in your datacenter or cloud VPC. It dials out to Spirex. never the other way around. Your private apps become unreachable on the public internet. Access is brokered through identity and policy, not firewall rules.
All connections originate from the connector: no inbound ports, no internet-exposed VPN endpoint, no attack surface.
Firewall replacement. retire the hardware, not the security.
Organisations approaching a firewall refresh can use the Spirex connector to eliminate the perimeter firewall entirely. Access is brokered through identity and policy, not permitted by port rules on an internet-facing appliance. Your applications simply disappear from the public internet.
