NAT-APP46: Building a Real-Time Stateless IPv4-to-IPv6 Protocol Engine

A technical walkthrough of how APP46 performs real-time stateless IPv4-to-IPv6 translation at the client, covering RFC 7915/6052 compliance, address mapping, TCP session handling, and the engineering decisions behind a protocol engine that runs transparently as a Windows service.

GPU-Accelerated Network Appliances: CUDA Kernel Offloads on NVIDIA Coprocessors

How IVO Networks leverages NVIDIA CUDA coprocessors to offload computationally intensive packet processing — including encryption, deep packet inspection, and traffic classification — from general-purpose CPUs to dedicated GPU cores for dramatic throughput gains.

IKEv2 VPN Architecture: Session Lifecycle, Rekeying, and Scale to 50,000+ Concurrent Tunnels

When enterprise customers ask how many concurrent VPN sessions a single appliance can sustain, the answer depends far less on raw throughput than on how the platform manages tunnel lifecycle at scale. At IVO, we engineered our IKEv2 implementation to handle 50,000+ concurrent tunnels — not by overprovisioning hardware, but by designing the session management […]

SSL/TLS Interception and HTTP/HTTPS Content Inspection in Enterprise Security Platforms

Breaking down the architecture of SSL/TLS interception in gateway appliances — how IngressGuard performs real-time certificate substitution, content inspection, and threat detection on encrypted HTTP/HTTPS traffic without degrading user experience or throughput.

Granular Access Controls: Building a Policy Engine for Enterprise and Government Deployments

Access control in enterprise and government networks is not a binary gate. It is not simply “allow” or “deny.” The real requirement is far more nuanced: allow this user, on this device, from this network, to access this specific application — and restrict everything else. Building a policy engine that evaluates those conditions in real […]

Firewall Engineering: Rule Engines, Signature Matching, and False Positive Management

The hardest problem in firewall engineering is not detection. It is the space between detection and noise. A firewall that catches every SQL injection attempt but generates hundreds of false positives per day is a firewall that gets its alerts ignored. A firewall that never fires a false positive but misses real attacks has a […]

FedRAMP Authorization While Maintaining Continuous Delivery

The practical reality of pursuing FedRAMP authorization for network security products without freezing your release pipeline — how to structure continuous monitoring, automate OSCAL documentation, maintain an Authority to Operate, and still ship updates on a regular cadence.

Multi-Protocol Authentication in Zero-Trust Platforms: Kerberos, RADIUS, and Policy-Based Access

Implementing Kerberos ticket-based authentication alongside RADIUS for network access control in a zero-trust architecture — how IVO Networks appliances enforce policy-based access decisions using identity, device health, and conditional access rules.
