“Fintech in security 2026”: RESTART and DAMASK - data protection in LLM prompts

On June 16, the international conference “Fintech in Security 2026” was held in Moscow. RESTART and DAMASK acted as partners in the business part and showed how to safely use external LLMs without leaking corporate data.

About the conference

On June 16, 2026, the annual international conference was held at the Moscow Congress Center "Palace of Cultures" "Fintech in safety 2026", organized by the consulting group Compliance Control & Rakasta. The event brought together over 200 executives and specialists from banks, fintech companies, marketplaces and retail, as well as IT experts, information security And artificial intelligence.

For the first time, the program was divided into two parallel tracks - business and technology - and the concept of the “Universe of Safe Payments” became the cross-cutting idea. Its meaning is simple: banks and fintech, marketplaces and retail Today they work in a single digital ecosystem, so the vulnerability of one participant instantly becomes a risk for everyone else.

Trust as a starting point

The main thesis of the program: security begins with trust. Any transaction - from the exchange of simple receipts to multi-billion dollar financial transactions - has always been built on this value. Today, when payments are processed in milliseconds and ecosystems integrate huge amounts of data, the cost of lost trust has increased manifold.

Trust is no longer a soft factor—it has become a measurable requirement for architecture, processes, and data control.

AI: both a threat and a tool

The reports and plenary discussion revealed the main paradox of the moment: artificial intelligence simultaneously enhances both the advantages of companies and their vulnerabilities. It does not create fundamentally new risks, but it multiplies existing ones – from data leaks to errors in decision making.

The industry's response is not to abandon modern language models, but to translate them into a manageable and secure loop: secure enterprise AI based on Restart AI Enterprise Platform, with permissions, logging, and verifiable responses instead of shadow chatbots.

DAMASK and DPD technology: data protection in the flow of LLM prompts

The DAMASK company (CEO Yuri Klochko) and RESTART (CEO Alexey Igonkin) acted as partners of the business part of the conference and focused on the key technology of the year - Dynamic Data Substitution (DDA) and its implementation in the form of a hardware and software complex DAMASK.

Organizations in all industries are faced with a new class of risk: sensitive corporate data, trade secrets and personal information fall into LLM prompts when working with public models. Each request to an external system can uncontrollably take beyond the perimeter what is the basis of the business.

DPD technology solves this at the architectural level and logically continues the practice masking and anonymization of data: Sensitive values ​​are tokenized before leaving the protected loop. The external model receives impersonal substitutes - mathematically correct for calculations, but useless for an attacker or regulator in the event of a leak. When returning a response, the system performs a reverse substitution and restores the original context within the perimeter. DAMASK for RESTART - part partner and vendor information security ecosystem.

What does this mean for fintech and banks?

For banks and fintech companies The combination of DPD and corporate AI solves several problems at once:

  • Protection of trade secrets when using AI assistants in analytics, customer service and sales support.
  • Readiness for inspections by FSTEC of Russia — data technically does not leave the protected environment in readable form.
  • Regulatory Compliance when working with modern LLMs: Federal Law No. 152-FZ and requirements of the Bank of Russia, Roskomnadzor order No. 140 dated 06/19/2025 and RF Government resolution No. 1154 dated 08/01/2025 - within the framework of a comprehensive IS compliance And licensed information security practice.

Separate environment - ready for digital ruble, where data and transaction protection requirements are particularly stringent.

RESTART: from architecture to industrial implementation

The practical implementation of such solutions on an enterprise scale is provided by RESTART, a technology group that combines competencies in information security, corporate AI, ERP and DevOps/DevSecOps. We cover the full cycle: from diagnostics and architecture design to implementation and managed support.

The synergy between DAMASK and RESTART is a complete combination: DAMASK provides data tokenization technology in the LLM stream, and RESTART integrates DPD into the existing infrastructure of a bank or fintech company. We are building role and access management, logging transactions with LLM in SIEM/SOAR/SGRC, Guardrails at the API level and compliance control through Security & Compliance AI. The knowledge base for assistants is Enterprise RAG, and with a quick start - RAG pilot.

New industry standard: protection from the first prompt

The conference documented key shifts in the approach to the security of AI systems:

  • built-in data protection from the first prompt becomes the new industry standard;
  • the security of the AI ​​environment is not a superstructure, but part of the foundation;
  • The era when protection was added “on top” of the finished product is becoming a thing of the past.

DPD technology in conjunction with RESTART expertise forms a reproducible template for a protected CorpGPT — ready for regulatory checks and not requiring abandonment of modern LLM tools. Helps you check the maturity of your AI environment Secure AI audit, and scale scenarios - secure AI automation.

Discuss secure enterprise AI

RESTART helps banks, fintechs and large companies safely implement corporate AI: design the architecture, integrate data protection into the LLM flow and pass regulatory checks. Get to know group leadership and you can discuss the pilot on the page contacts.
