Hi, I'm Tamas Zumpf

I am a CTO, visionary, and expert in scalable security, specializing in end-to-end encrypted communication, privacy-first technologies, and zero-trust security architectures. My expertise spans cybersecurity, cryptography, blockchain security, and large-scale digital platforms, ensuring that digital communication is private, scalable, and resilient. As an advocate of Messaging Layer Security (MLS) in the UAE, I focus on advancing secure group communication standards to protect modern digital interactions.

My experience extends beyond security into building and scaling high-traffic digital services, including leading video streaming technology efforts at HBO, OSN and more. I understand the challenges of delivering secure, high-performance platforms at scale, having worked on media distribution, digital infrastructure, and content delivery networks in complex enterprise environments.

Beyond technology, I am a firm believer in empathetic leadership, fostering teams that innovate, grow, and collaborate effectively. I see security not just as a technical challenge, but as a trust-building exercise, where the human element is as critical as the cryptographic one. My mission is to bridge technology and leadership, creating security solutions that empower both businesses and individuals.

Messaging Layer Security (MLS) is a modern cryptographic protocol designed to secure group communication with end-to-end encryption. Unlike traditional messaging protocols, MLS is scalable, making it ideal for environments where multiple participants require private, real-time communication. It ensures data is protected from eavesdropping, even during large-scale interactions. MLS is particularly relevant for businesses seeking privacy-first solutions, enterprises needing secure collaboration tools, and developers building encrypted platforms that prioritize trust and resilience.

I specialize in helping businesses implement scalable security architectures, adopt privacy-first technologies, and design encrypted communication solutions. My expertise includes working with large-scale platforms that require robust encryption protocols like Messaging Layer Security (MLS). Whether your business needs to secure sensitive user data, build trust through privacy-driven innovation, or lead high-performing tech teams, I bring the technical knowledge and leadership skills to drive success. My background spans industries like secure communication, blockchain, and media technology, ensuring a comprehensive approach to solving your challenges.

Privacy-first solutions are the foundation of trust in modern digital platforms. As regulations like GDPR and UAE Data Protection Laws continue to evolve, businesses must prioritize privacy to avoid legal risks and build stronger relationships with users. Privacy-first systems also enhance brand loyalty by showing users that their personal data is respected and secure. By implementing technologies like end-to-end encryption and zero-trust architectures, businesses can protect sensitive information, foster trust, and ensure long-term success.

Agentic AI refers to AI systems that operate autonomously, making decisions, executing tasks, and adapting based on goals and real-time data. Unlike traditional AI models, agentic AI can plan, reason, use tools, and collaborate with other agents to achieve complex objectives. It enables multi-step, goal-driven workflows without constant human intervention.
