To empower enterprises through powerful, simple, and comprehensive access control that minimizes complexity and elevates security.
Every organization — regardless of size, industry, or infrastructure — deserves complete control over who and what accesses their applications. Without compromise. Without complexity. Without six vendors and twelve consoles.
Two decades of solving problems others won’t touch
PortSys was founded with a simple belief: organizations shouldn’t have to choose between security and usability, between cloud and on-premises, or between compliance and convenience.
We built Total Access Control because we saw enterprises struggling with fragmented security stacks — juggling multiple vendors, multiple consoles, and mounting license fees just to achieve basic access control. Legacy applications were being left unprotected because modern tools couldn’t secure them. Open firewall ports were multiplying. And then AI agents arrived, creating an entirely new class of identity that no one was governing.
TAC started as a reverse-proxy access solution for organizations that needed to protect applications without modifying them. Over the years, it evolved into a comprehensive zero-trust platform — adding MFA, continuous device posture, identity federation, SSO, and AI agent governance — all while maintaining the architectural simplicity that makes it deployable in hours, not months.
Today, TAC protects organizations across government, healthcare, financial services, manufacturing, education, and technology — from small departments to global enterprises spanning multiple continents.
Principles that shape everything we build
These aren’t marketing talking points. They’re the constraints we design to and the promises we ship against.
Security Without Complexity
Zero trust shouldn’t require a team of 12 and six management consoles. TAC delivers enterprise-grade security from a single admin interface that deploys in hours — because security that’s too complex to implement is security that doesn’t exist.
Customer Control
Your data, your infrastructure, your rules. TAC’s single-tenant architecture means your security is never shared with another organization. Deploy on-prem, in your private cloud, or in public cloud — wherever you need to maintain sovereignty.
Inclusive Licensing
Every capability. Every feature. Every integration. One price. No per-user MFA surcharges, no premium tiers for device posture, no surprise add-ons at renewal. We believe security features shouldn’t be paywalled.
Legacy Doesn’t Mean Left Behind
Billions of dollars of enterprise value runs on applications that were built before zero trust existed. We believe those applications deserve the same security as cloud-native SaaS — and TAC delivers it without a single code change.
