Firewall rules
Every change is a ticket
New laptops, new staff, new SaaS tools, people leaving. Each one needs a rule, and nobody dares to delete the old ones.
Network security that lives on every device
Nexufend protects every device from the inside, controlling exactly which app communicates with what. All software, encrypted by default, built for resilience.

Your network changes every day. Your security setup doesn't keep up.
VPN gateway
Every VPN is one more door
Remote staff need a way in, so a VPN gateway joins the firewall. One more internet-facing system to patch and maintain, and one more target for attackers.
Zero trust (ZTNA)
Zero trust stops at the device
ZTNA checks the user and the laptop, then every program on it shares that access, malware included. Many services also route your traffic through the vendor's cloud.
Nanosegmentation and Intentional Trust
Every process gets its own segment
Firewalls segment by network. Zero trust segments by user and device. Both stop one level too high: once a device is in, every program on it shares the same access.
Nexufend segments down to the process. We call it Intentional Trust: every application reaches only the destinations you've authorized for it, verified by its binary hash and code signature. Between your devices, both sides check before a connection goes through, and that keeps working when the internet is down.

Rules in days, by app name
Nexufend learns your everyday traffic and suggests about 80% of the rules for you. A new tool means approving one rule.
No VPN gateway to expose
Company devices connect to each other directly and encrypted. The same rules hold in the office, at home or on a public network.
Access per program
Each program reaches only the destinations you've authorized for it. A program you never authorized reaches nothing, even on a trusted laptop.
Start with your critical systems and make sure only the right processes can reach them.
Why detection alone can't keep up with AI-driven attacksInstall the agent, let it learn what your apps need, then decide what's allowed.

Nexufend recognizes an application by its binary hash and code signature, not by its name or path. Renaming a file doesn't get it past the rules.

Why software beats hardware
Nano-segmentation
Every process on every device is isolated and individually controlled. Compromise one app and it stays boxed in, reaching only what you authorized. Lateral movement has nowhere to go.
Process-level control
Rules are about applications, not IP addresses. Allow Outlook to reach Exchange, and nothing else. That rule holds when servers move, IPs change, or ports get reassigned.
Complete visibility
See every internal and external connection in real time, with the process behind each one. You watch what's actually happening, not a wall of network metadata.
End-to-end encryption
Every connection between your devices is encrypted and authenticated automatically. A bank transaction and a print job get the same protection.
No hardware
Run across cloud, remote, and hybrid setups with nothing to rack or maintain. Updates roll out in minutes, and there's no appliance to fail.
Efficient configuration
Configure the things you know and care about: devices and applications. Skip the IPs, ports, and subnets.

Get in touchA path off hardware, on your schedule
A hardware firewall is a big up-front spend, real ongoing effort to run, and one box your whole site depends on. Most teams want off that eventually. You can start today without ripping anything out: add Nexufend as a layer, run both side by side, and retire the hardware when it makes sense for you.
