Thales strengthens data protection amid AI and quantum risks.

Thales strengthens data protection amid AI and quantum risks. AI adoption, expanding data volumes and the emerging threat posed by quantum computing are prompting enterprises to reassess their cybersecurity strategies. Growing demand for platform consolidation is also encouraging organisations to integrate data security, application security and identity and access management capabilities. In an interview with TahawulTech.com at GISEC Global 2026, Sébastien Pavie, Vice President of Sales - SEMEA at Thales, discusses the company's latest data protection and quantum-safe security developments. He also examines the dual role of AI in strengthening cyber defence and enabling more sophisticated attacks, highlighting the importance of protecting sensitive data throughout its lifecycle. How did you find GISEC Global 2026 compared with previous editions? The new venue at Expo City Dubai brought fresh energy to GISEC Global 2026. The event was extremely busy, which reflected strong engagement from the cybersecurity community. GISEC continues to provide an important platform for Thales to connect with customers and partners, discuss evolving security priorities and present its latest product developments. What did Thales demonstrate at GISEC Global 2026? Thales showcased capabilities across data security, application security, and identity and access management. Customers increasingly want to consolidate products and vendors, so Tahawultech continue to combine complementary solutions within integrated platforms. One of its latest developments brings data protection capabilities together within a single platform, covering the discovery, visibility, protection and control of sensitive information. Tahawultech also introduced a next-generation, quantum-ready hardware security module designed to help organisations prepare for the potential impact of quantum computing on current encryption methods. What should guide enterprises when selecting AI-powered cybersecurity technologies? Enterprises should first recognise AI's dual role in cybersecurity. Attackers can use AI to increase the scale and sophistication of threats, while defenders can apply the technology to strengthen detection, protection and response. AI adoption also creates and processes significantly larger volumes of data, making data-centric security more important than ever. Organisations should therefore assess whether a security technology can protect sensitive data throughout its lifecycle, support AI use cases and defend against AI-enhanced threats. Regulatory requirements, integration capabilities and opportunities to consolidate existing security tools should also guide technology selection. What would be your closing advice to CISOs who attended GISEC Global 2026? CISOs should use the event as an opportunity to reassess their security priorities against a rapidly changing technology and regulatory landscape. AI-related risks and the growing focus on post-quantum security require organisations to review whether their current controls remain fit for purpose. Security leaders should evaluate solutions that strengthen data protection, prepare their organisations for quantum-related risks and support secure AI adoption. GISEC offers access to a broad range of technologies that can help CISOs identify gaps and adjust their cybersecurity strategies accordingly. Image Credit: Thales

American sets the scene for geek out on XLR - and at Cranky Dorkfest.

American sets the scene for geek out on XLR - and at Cranky Dorkfest. For the second time in my #AvGeek career, there's a premium transcon arms race kicking off. The 2010s saw the introduction of a totally overhauled United p.s. service, American's launch of the dedicated transcon Airbus A321T, and Delta's entry into the ring with widebody aircraft. The latter half of the 2020s saw this race restart. United has its A321 Coastliner, American has its A321XLR, and Delta is planning but is so far unable to launch its own premium A321 subfleet. American was the first mover to get its latest and greatest Airbus narrowbody into service, and on a recent flight from Los Angeles to New York JFK, I decided to give it a go in the Main Cabin. (You can check out Chris Sloan's recent reviews of Flagship business and Premium Economy here on RGN.) I was in Los Angeles to attend Cranky Dorkfest and to my surprise American had a couple of aircraft on static display, including the A321XLR. The U.S. major is clearly quite proud of the long-haul narrowbody, going as far as to print mock boarding passes to welcome Cranky Dorkfest attendees. With the A321XLR on static, I was able to get some clean shots of the hard product before my flight to New York (which are interspersed throughout this trip report). The aircraft features 123 seats in Main Cabin economy class, six fewer than United's upcoming Coastliner. At the same time, American features just two rows of Main Cabin Extra seats at the front of the cabin. Although these seats feature extra legroom, it seems that neither row of seats reclines. Given the long flights these aircraft will operate in Summer 2027, Main Cabin Extra may actually be seats to avoid. I sat in the row directly behind Main Cabin Extra, which may be the best Main Cabin row on the aircraft since the seats in front of you don't reline. This product is quite simply very unlike the American Airlines I know. The XLR was designed before American decided to reverse its decade-old course and announce it would bring back seatback screens to all narrowbody aircraft. Though the XLR was intended to be something special and unique, it may now be the blueprint for the rest of American's fleet. For an economy seat, it has everything. Enough legroom for a longer trip (an empty middle seat on my LAX-JFK flight helped, for sure), a big and modern seatback screen, USB-A and USB-C ports, an AC power outlet with yet another 60 watt USB-C port, Bluetooth audio and redundant 3.5mm headphone jacks. As far as a modern economy seat on a narrowbody aircraft goes, this is as good as it gets these days. American's XLR is equipped with Thales' AVANT entertainment system with 4K HDR screens using Samsung's QLED technology. While all the specs and improved technologies are great, I was most excited to see American finally put some effort into its graphical user interface. (I don't think it had changed the interface since before the US Airways merger when the Airbus A321T was introduced to the fleet.) It became immediately apparent that this IFE system is leaps and bounds more modern than the legacy equipment. The GUI is intuitive and cleaner than what it replaced. It's also fully featured with functions like Watch Party (though this activity didn't work nearly as well as on a recent JetBlue Airbus A220 flight), and kept up with my interactions. Bluetooth audio, a feature that is no longer just a nice to have option, is of course present and worked without issue. I couldn't tell if any content was actually available in 4K, with only some movies including "HD" in the title. The screens seemed to have a privacy film applied, making it difficult to see what was being displayed on other screens in the cabin. This typically reduces overall brightness. However, I watched Avatar: Fire and Ash and it looked fantastic with rich colors and vibrant highlights. In an interesting twist, American even offered a free small meal in Main Cabin on my LAX-JFK flight, and it does the same for a few other key premium routes. This is a perk that Delta once offered on an array of transcon routes prior to the COVID-19 pandemic but never brought back. I opted for the curry chicken croissant sandwich which was packaged in a box alongside a bag of baked veggie snacks and a Brookie bar. A cheese tray and hummus dip alternatives were also available. Expecting the meal on board to be small and inadequate, I had in fact bought a salad in the terminal before departure. But I was pleasantly surprised at the completeness of what was offered. The XLR sports the typical Viasat-powered connectivity system, which performed about as well as usual for the system. It worked for a while, didn't work at all for another while, but was generally just fine. Viasat suggests that passengers should expect to see reliably higher speeds as airlines are onboarded to its new ultra-high-capacity ViaSat-3 F2 satellite over the Americas. It's amazing how quickly LEO-powered systems like Starlink have spoiled me, however. American no longer charges for Wi-Fi, at least, so I can hardly complain. While onboard, I couldn't help but draw comparisons between American's XLR transcon service and how I used to feel flying Delta before the pandemic. Here, American is offering a seatback screen with ample entertainment, friendly service, free Wi-Fi that (mostly) worked, and even a free meal that I can only assume next to no passengers knew they'd be getting. This is the type of service that kept me loyal to Delta until COVID changed the equation. I'm excited to see how American brings this experience back to the rest of its fleet.

Dassault and Thales are testing two new sovereign artificial intelligence algorithms on board a Rafale.

Dassault and Thales are testing two new sovereign artificial intelligence algorithms on board a Rafale. Dassault Aviation, together with Thales, has completed the first flight tests of two sovereign artificial intelligence algorithms integrated into a Rafale fighter aircraft. One was developed by Dassault's own engineers, while the second was developed in collaboration with cortAIx, Thales' artificial intelligence accelerator. On September 22, the manufacturer stated that both algorithms had reached a sufficient level of maturity to be considered for future upgrades to the aircraft, although it did not disclose the dates of the flights, the specific variant used or the functions evaluated. For the French aerospace industry, this marks the first time that two algorithms of this kind have been executed and evaluated aboard a combat aircraft under actual flight conditions. Dassault presents them as part of a controlled and supervised artificial intelligence capability, designed to support the crew rather than replace it. In other words, these algorithms are intended precisely to reduce the crew's workload and maximise its effectiveness. Dassault and Thales have not yet identified the specific tasks performed by the two algorithms. However, the strategic agreement signed by the two companies in November 2025 envisages applications in observation, tactical situational awareness, decision support, mission planning and the coordinated control of crewed and uncrewed platforms. All these functions could help reduce the pilot's cognitive workload when simultaneously managing sensors, data links, weapons, electronic threats and collaborative aircraft. Both companies aim to address a major operational challenge: the growing volume of information available in the cockpit. A modern Rafale, for example, receives data from its radar, optronic system, electronic warfare equipment, tactical data links and other platforms. Artificial intelligence can help correlate these inputs, eliminate duplication, prioritise threats and propose courses of action. Furthermore, in collaborative combat, it can distribute tasks between the crewed aircraft and several drones, avoiding the need for the pilot to directly control every manoeuvre performed by each platform. Facing such a volatile global security environment, conventional information is no longer sufficient. Rise above media noise by accessing independent and rigorous analysis.
