Enterprise Security.
Zero Compromise.

Tangent Networks UTM is a fully self-hosted control plane built on OpenBSD. PF firewalling, Unbound DNS-over-TLS, e2guardian filtering, SSL/TLS interception via sslproxy, and Snort in both IDS and IPS modes operate locally under explicit constraints. No cloud dependency, no external control plane, no hidden trust boundaries. Every component is observable and under your authority.

The system enforces strict separation by design. The web interface cannot execute privileged operations and has no escalation path. All state changes move through a file-based queue and are executed by independent root daemons outside the web context. The interface can request, but it cannot act.

Security is enforced through layered inspection, not reactive controls. PF blocks at the edge, Snort detects and actively prevents malicious patterns, sslproxy enables inspection of encrypted traffic, e2guardian filters content, and Unbound resolves queries without exposure. Each layer operates independently, preventing failure from propagating across the stack.

Protect your digital storefront with military-grade web application security. Tangent Webserver delivers enterprise-class protection customized to your exact specifications, combining high-performance infrastructure with intelligent threat defense. Our integrated Web Application Firewall (WAF) stops attacks before they reach your applications—blocking SQL injection, cross-site scripting, file inclusion exploits, and CSRF attacks in real-time.

Every deployment includes DDoS mitigation, VPS encryption, sophisticated access controls, automated daily backups, and an intuitive admin panel. You'll receive email notifications for critical events, fully customized threat intelligence feeds, archived audit logs for compliance, and comprehensive daily security reports.

Whether you're running an e-commerce platform, processing financial transactions, or delivering SaaS applications, Tangent Webserver shields your business from data breaches, maintains customer trust, and protects your reputation.

Your email is mission-critical. Tangent Mailserver provides fortress-level protection with multiple defense layers against malware, spam, phishing, and business email compromise. We implement cutting-edge encryption standards—including MTA-STS, TLS 1.3, DANE, and client certificates—ensuring your communications remain confidential and authenticated.

Our platform stays ahead of threats by deploying the latest email authentication protocols (DKIM, DMARC, ARC) immediately upon release. Advanced traffic splitting enables zero-downtime deployments while our parallel testing environments guarantee smooth version migrations without disrupting operations.

The multi-engine threat detection system identifies and neutralizes attacks across vectors, from malicious attachments to sophisticated social engineering attempts. Protect your communications, maintain compliance, and ensure business continuity with email security that evolves with the threat landscape.

Stop threats before they enter your network. Tangent DNS Firewall operates at the foundation of your security stack, blocking malicious connections at the DNS level—before malware can install, before data can be exfiltrated, before command-and-control channels can be established.

Our purpose-built solution intercepts and blocks requests to known malicious domains and IP addresses in real-time, preventing infections across all connected devices. Advanced rate limiting throttles suspicious DNS request patterns while intelligent caching and DDoS mitigation maintain peak performance under attack.

Tangent DNS Firewall disrupts phishing campaigns, prevents botnet communications, blocks DNS tunneling attempts, and stops malware from calling home to attackers. Unlike traditional perimeter defenses that react after intrusion, DNS-level protection prevents the connection entirely.

Transform your network infrastructure for the cloud era. Traditional WAN architectures can't keep pace with modern business demands—Tangent SD-WAN delivers the agility, performance, and security your organization needs. Our intelligent network fabric creates optimized connections across your entire infrastructure, extending application and security policies seamlessly beyond traditional boundaries.

Scale effortlessly as your business grows—add new sites, expand bandwidth, or adjust capacity in minutes using standard Internet connections instead of expensive MPLS circuits. Tangent SD-WAN adapts instantly to your evolving needs, rapidly provisioning hub-and-spoke, full mesh, or hybrid network topologies without lengthy deployment cycles.

Reduce WAN costs dramatically while improving application performance, strengthening security posture, and simplifying management. Your network should enable growth, not constrain it.

See every packet. Detect every threat. Tangent Netflow provides real-time network visibility that transforms your security operations. Instantly visualize and analyze traffic flows across your entire infrastructure with precision insights that enable rapid threat detection and network health assessment.

Our platform integrates continuously updated threat intelligence feeds, automatically identifying malicious IPs, suspicious domains, and attack behaviors before they impact your operations. Advanced packet capture and replay capabilities let you reconstruct security incidents with forensic-level detail, uncovering vulnerabilities and attack vectors that traditional monitoring misses.

Purpose-built for enterprise security teams, Tangent Netflow integrates seamlessly with your SIEM and SOC workflows, delivering actionable intelligence that accelerates incident response. From anomaly detection to compliance monitoring—give your security team the visibility they need to stay ahead.
