AI vs AI in Cybersecurity: When defenders and attackers both use AI

The game has changed, clearly. Attackers have AI, defenders have AI, and both sides are learning faster than anyone expected, or maybe the attackers are just a bit faster. What used to take hours now happens in seconds, and detection windows close before alerts even appear. It’s adaptation beyond automation, and no one gets to sit still. But every promise of AI-driven defence comes with a price. The tools are expensive to train, maintain, and monitor. Mistakes cost more too. False positives drain teams, model drift hides real threats, and poisoned data turns protection into confusion. So now it’s not only about defending networks, it’s about defending the defenders themselves, from fatigue, blind trust, and automation gone wrong. So how do you keep visibility when both sides use the same weapons? How do you detect intent when patterns look human but aren’t? How do you justify cost when failure still happens, just faster? Let’s explore what happens when algorithms face each other on both sides of the firewall, and what new defences emerge when speed alone is no longer enough. A closed conversation about a future where cybersecurity becomes an AI vs AI battle, and humans still have to win.

Replace, Wrap, or Rebuild? : Core modernization in financial services and insurance, without a full rewrite.

For banks, insurers, and other financial services leaders, core modernization is rarely a simple technology decision. The harder question is what to replace, what to wrap, what to rebuild selectively, and what to leave alone. This round table brings together senior peers to discuss how they are making those choices under real constraints: resilience, control, regulatory scrutiny, delivery speed, vendor dependency, and the risk of getting sequencing wrong. The conversation will focus on practical judgment, where modernization creates value, where it adds risk, and how to move forward without triggering another multi-year transformation cycle. A small-group discussion for leaders looking for clear decisions, credible trade-offs, and peer perspective.

Managing Vendor Lock-In: Balancing dependence, cost, and control in strategic partnerships

Every vendor swears their platform is open, flexible, and built for freedom. Then comes the renewal date. The price goes up, migration looks painful, and “strategic partnership” starts to feel more like dependency. Most organisations don’t get trapped overnight, they walk into it one contract at a time. Broadcom, anyone? We know lock-in isn’t only technical, it’s commercial, architectural, and even cultural. Once tools shape how teams work, switching becomes not only costly but politically impossible. So how do you manage dependency without losing leverage? What do you do when moving away costs more than staying? How do you negotiate from a position of weakness? And what governance models help prevent lock-in before it happens? Let’s share how to keep options open, make vendors compete without breaking partnerships, and find leverage even when it seems there’s none left. A closed conversation for those who’ve learned that freedom in IT is rarely free.

The Career Path of the Cloud Engineer: From system builder to strategic enabler of digital scale

The cloud engineer’s world keeps expanding. It started with provisioning and automation, but now it touches everything: resilience, security, cost, and even business continuity. What used to be a back-end function has become one of the most visible roles in digital operations. Yet with that visibility comes pressure: constant evolution, constant firefighting, and very little time to step back and ask, “Where is this career actually going?”

Post Office Delivers Application Fast With OutSystems

Learn how U.K. financial services retailer Post Office started its wide-scale digital transformation with the delivery of its first travel product mobile app, which they delivered in a record-breaking timeframe using OutSystems.

Pioneering New Revenue Streams Via Digital Transformation

Challenge - U.K. financial services retailer Post Office wanted to create new revenue streams from within their unique network of 11,500 retail outlets and the 17 million customers coming through their stores each week. To do that, Post Office decided to pioneer a digital transformation, starting with a new business-to-consumer (B2C) native mobile app for Android and iOS to promote the company’s financial products for travel. With a 25 percent market share for travel money and a 7 percent share of travel insurance in the U.K., their new mobile app needed to be highly robust and scalable. The challenge was increased by a necessity for integration with legacy systems managed by third parties, and by the fact that this was the first native mobile application created by the Post Office team. They needed a development platform that offered advanced security, code reusability, and allowed for greater data insight to help them get to market faster.

Low-Code Enables Application Development and Easy Integration

Solution - Using OutSystems, the newly formed Business Innovation team at Post Office developed, tested, and released Post Office Travel, their first native mobile app for their travel money and insurance products. And they did it at a speed virtually unheard of in bringing a new mobile financial product to market - just four months. The new app allows customers to buy and manage a Travel Money Card and to select Travel Insurance at the same time, as well as use GPS to locate nearby Post Office branches and ATMs. The team was able to swiftly navigate the numerous regulations and controls financial projects are subject to and integrate the solution with legacy systems managed by third parties from First Rate Exchange Services, Post Office Insurance, and Accenture.

A Proven Platform Primed for Future Innovation

Results - The new app was released to the iOS and Android stores in record time, and within three months, the new native mobile app was adopted by more than 100,000 customers. Using the OutSystems low-code platform dramatically accelerated time to market and simplified the organization’s integration challenges with complex back-end systems. Moreover, OutSystems is serving as the foundation for their future digital strategy of creating new revenue streams to serve its 17 million customers across the U.K.

"With a history that goes back for centuries, Post Office is revitalizing services and building new revenue streams. OutSystems is the cornerstone of our strategy to serve over 17 million customers better."Henk Van Hulle, Managing Director, Group Digital and Innovation at Post Office
