C-Deep (formerly known as RTLX developed by Insider Technologies Limited) is an enterprise-grade, real-time transaction and payment monitoring software product. It is currently owned, maintained, and distributed globally by ETI-NET.

Product Overview & Key Features

The primary objective of C-Deep for HPE NonStop is to ensure fault tolerance, detect transactional vulnerabilities, and prevent outages within major financial ecosystems.

• Target Environment: It is deployed alongside primary mission-critical payment engines, primarily operating as a high-performance add-on to ACI Worldwide’s BASE24™ solution or as a standalone tracker on HPE NonStop systems.
• Architecture: The software utilizes lightweight extraction clients on the NonStop kernel to read Transaction Log Files (TLF) and POS Transaction Log Files (PTLF). It offloads data parsing to a C-Deep collector on Windows Server, keeping the primary switch’s CPU overhead at zero.
• Data Retrieval: It stores and indexes historical transaction fields into annual databases for 10+ years, making it fully searchable to meet strict data regulatory compliance laws.
• Granular Querying: Operators can isolate variables down to Bank Identification Numbers (BIN), detecting interchange timeouts, clearing delays, or switch drops down to the millisecond.

Detailed Timeline Breakdown by Era and Year

The technical evolution of this platform reflects the wider political and economic changes in global banking, transitioning from early bespoke mainframe logs to modern, automated cyber-resiliency environments.

🔹 The Foundational & Legacy Tandem Era (1989–2000)

This era centered around high-security, fault-tolerant mainframes built for NATO-aligned military communications and early banking networks following the end of the Cold War.

• 1989: Insider Technologies Limited is incorporated in the UK to manufacture specialized monitoring code for highly robust computer systems.
• 1990–1995: The vendor releases its foundational “Reflex” software suite for the Tandem Guardian operating system, offering real-time transaction diagnostics without interrupting physical processing operations.
• 1996–1999: The platform adds “MultiBatch” automation to orchestrate complex batch settlements. Engineering pivots toward critical Y2K code auditing to prove that automatic logging routines would survive the year 2000 date rollover.

🔸 The Multi-Platform & Financial Compliance Era (2000–2015)

This era mark’s the product’s rise to prominence as a core tool for transaction transparency across global clearings houses, reacting to rapid financial sector deregulation.

• 2001–2003: The architecture scales up from simple hardware tracking into dedicated operational security. The vendor expands the footprint into financial clearings, tracking transaction security for system-critical clearers like the Bank of England.
• 2004–2007: The developer releases RTLX (Real-Time Transaction Logging/Reactor), standardizing visibility from the point-of-sale terminal tap to the back-end ledger settlement. It adds cross-compatibility for Windows, Unix, and Linux systems alongside standard Tandem NSK systems.
• 2008–2012: Amid market volatility following the 2008 financial crash, transaction tracking rules tighten. RTLX adds specialized configuration engines to map high-volume dates (e.g., Black Friday) to proactively flag message queues and clear bottlenecks before causing outages.

🔹 The Acquisition & Integration Era (2015–Present)

This era sees consolidation in the HPE NonStop market, transforming the legacy product into a fully modern cyber-resilient and automated tracking ecosystem.

• 2015–2021: Real-time transaction frameworks become critical for compliance. To expand global distribution channels, ETI-NET formalizes an agreement to acquire and absorb Insider Technologies’ core system software catalog.
• 2022–2023: ETI-NET rebrands the classic software stack to streamline its message. The system monitoring side (Reflex) becomes Sentinel, while the specialized payment switch transaction monitor (RTLX) is official re-launched as C-Deep for Transaction Monitoring.
• 2024: ETI-NET pushes C-Deep through HPE Pointnext Services, making it directly purchasable within standard Hewlett Packard Enterprise customer channels. Integrations are updated to match the NIST 2.0 Cybersecurity Framework.
• 2025–2026: Modern upgrades focus heavily on end-to-end data auditing, automated email/SMS alerting systems, and specialized dashboard analytics tailored for complex, multi-currency transaction paths.
