c/side: The Client-Side Platform for Cybersecurity, Compliance, and Privacy
Monitoring third-party scripts effectively eliminates uncertainty, ensuring that you are always aware of what is being delivered to your users' browsers, while also enhancing script performance by up to 30%. The unchecked presence of these scripts in users' browsers can lead to significant issues when things go awry, resulting in adverse publicity, potential legal actions, and claims for damages stemming from security breaches. Compliance with PCI DSS 4.0.1, particularly sections 6.4.3 and 11.6.1, requires that organizations handling cardholder data implement tamper-detection measures by March 31, 2025, to help prevent attacks by notifying stakeholders of unauthorized modifications to HTTP headers and payment information. c/side stands out as the sole fully autonomous detection solution dedicated to evaluating third-party scripts, moving beyond reliance on merely threat feed intelligence or easily bypassed detections. By leveraging historical data and artificial intelligence, c/side meticulously analyzes the payloads and behaviors of scripts, ensuring a proactive stance against emerging threats. Our continuous monitoring of numerous sites allows us to stay ahead of new attack vectors, as we process all scripts to refine and enhance our detection capabilities. This comprehensive approach not only safeguards your digital environment but also instills greater confidence in the security of third-party integrations.

Agentcard
Agentcard provides a secure method for AI agents to conduct online transactions by generating disposable virtual Visa cards tailored for agent operations. This innovative solution eliminates the need to share actual card information in conversations or require human intervention for checkout, as users can issue single-use cards that come with predetermined spending limits and automatically deactivate after a single authorized transaction. The system is built around user control, ensuring that every card and charge requires human approval, that real card information is never disclosed to agents, and that users receive alerts whenever an agent attempts to create a card or execute a payment. Furthermore, it seamlessly integrates with various platforms, including ChatGPT, Claude Desktop, Claude Code, OpenClaw, Cursor, and MCP-compatible agents through one-click setups, an MCP server, CLI tools, REST API, a Chrome Extension, and administrative tools for organizations. Users have the ability to create cards, monitor balances, review transaction histories, deactivate cards, and utilize these cards for online purchases while maintaining oversight and control throughout the process. This user-centric design ensures that the integrity and security of financial transactions remain uncompromised, allowing for a smooth and efficient interaction between agents and payment systems.
