Mirror Security Appoints Former COO of RSA Security - Albert Sisto as Independent Board Member
Former COO of RSA Security joins Mirror Security's board as the company builds the encryption layer for the AI era
DUBLIN, IRELAND | 20th March, 2025 | www.mirrorsecurity.io
Mirror Security, the deep tech AI security company pioneering encrypted AI inference for regulated industries, today announced the appointment of Albert (Al) Sisto as an Independent Board Member. Sisto brings more than 40 years of experience across public companies, startups, venture capital, and private equity, and is widely regarded as one of the foundational figures in enterprise security software.
As a former Chief Operating Officer at RSA Data Security Inc. — the company that became the global standard for public-key encryption and digital trust — Al helped lead its landmark transformation from a passive patent licensing operation into an aggressive, sales-oriented software company that secured the foundations of global digital commerce. His career has since spanned roles as a Technology General Manager and Venture Investor, consistently identifying and scaling category-defining technology companies.
Mirror Security, a research-driven cybersecurity company, spun out of University College Dublin, Ireland. Offers the world's first production-ready fully homomorphic encryption (FHE) engine optimized for AI workloads, providing cryptographic controls.
When enterprises query LLMs, their proprietary intelligence is processed in plaintext — visible, extractable, and vulnerable to distillation.
When frontier models serve inference, their outputs can be harvested to train competing models for pennies on the dollar. Intelligence leaks both ways. No one is protected
Mirror enables AI computation on data that never decrypts (Encryption in Use) — securing inference, memory, and the entire AI pipeline end-to-end.
"In the early days of the internet, securing online commerce was the critical requirement — and RSA became the foundation of trust for digital transactions worldwide. Today, securing the usage of AI is an opportunity orders of magnitude larger. The team at Mirror has developed a platform that I believe can surpass the success of RSA, creating the encryption layer for AI that enterprises and governments urgently need."
Albert (Al) Sisto, Independent Board Member, Mirror Security | Former COO, RSA Data Security Inc.
Sisto's appointment signals Mirror Security's intent to accelerate its enterprise go-to-market strategy and deepen its engagement with regulated industry leaders globally. His operational expertise in scaling security software businesses and his extensive network across the technology and investment communities position him as a key strategic asset as Mirror moves from early traction into its growth phase.
"We are truly excited to welcome Al to the Mirror Security board. His experience building RSA into the global standard for digital trust is not just a credential — it's a blueprint. Al has done this before: taken a cryptographic breakthrough and turned it into an enterprise-grade product that the world came to depend on. As we enter our next phase of growth, Al's strategic guidance, his enterprise relationships, and his deep understanding of how security categories are built will be invaluable. We look forward to working alongside him to make Mirror Security the encryption layer that the AI era demands."

The paper titled "Manipulating Prompts and Retrieval-Augmented Generation for LLM Service Providers" published by Mirror Security research team, explores significant security vulnerabilities associated with large language models (LLMs) and their service providers. It highlights two primary attack vectors: the manipulation of generative search engines and the injection of biased content into LLM outputs. This blog will summarise the key findings and implications of the research.
