Every AI Agent Needs a Guardian. We Built It. AI agents are the most powerful and most ungovernable workforce your organization has ever deployed. They write code, access databases, make API calls, and take autonomous action across your most sensitive systems. They move fast. They dont ask permission. And when they go rogue, no one sees it coming. Until now. Capsule Security is the runtime security platform for AI agents. Our Guardian Agent technology monitors every action an AI agent takes in real time and enforces security policies before damage is done. No proxies. No gateways. No SDKs. Just seamless, native integration that gives your security team full visibility and real-time control without slowing anything down. We dont scan. We dont log after the fact. We enforce. What makes us different: → Patented fine-tuned small language models that understand agent intent, not just tokens → Native hooks and API-level integration with leading AI platforms → Real-time policy enforcement that stops threats mid-action → Full visibility into the complete agent action chain → Zero friction for engineering teams. No code changes, no architectural rework Capsule was named a Representative Vendor in Gartners inaugural Market Guide for Guardian Agents. Our research team has disclosed zero-day vulnerabilities in AI Agent platforms, because we believe the industry deserves to know what AI agents are actually capable of. Backed by LAMA Partners and ForgePoint Capital International and advised by leading security leaders. Your AI agents are already inside your perimeter. The question is: whos watching them? We are.

Zeroport is the first non-IP secure remote access solution provider. Using a patented physical bridge deployed at the gateway of an organization’s network, Zeroport enables only human interactions in and only a stream of pixels out - so no packet (no digital signal) enters or exits the network, all while enabling latency-free work at linear scale. This approach solves the biggest network access pains for both isolated and connected networks - it brings air-gapped networks from 0 to 1 in their remote access journey by enabling secure connectivity from remote locations while keeping their air-gap intact. For connected organizations relying on traditional remote access stacks, Zeroport helps modernize and simplify their cumbersome, costly and vulnerable remote access approach, currently plagued with extreme vendor fatigue and security-patch chaos. With offices in New York, Israel and Singapore, Zeroport serves financial institutions, critical infrastructure, industrial enterprises, and public-sector organizations worldwide.

The business landscape is fundamentally changing – the way and location of work has been transformed. Furthermore, with mass migration to the cloud, SaaS is vital. All this creates new risks - numerous points of access from multiple devices and multiple locations increase the attack surface. To address these attacks, your security solution should fundamentally change as well. Thats where SURF enters. SURF provides users with freedom of work, letting them interact with applications, data, and each other securely. It addresses the critical business asset neglected by security experts for years: The browser. The browser is the access frontier for everything: users, data, corporate assets, applications, development activities - and cyber criminals, too. SURF Security has transformed the browser into your strongest security asset while providing complete end-user privacy – all with full compliance. Through this centralized platform, SURF insists on identity-first access to all SaaS and corporate assets to guarantee a secured and frictionless user experience. SURF enhances security, performance, and productivity for end-users and applications – faster than ever before.
