Tenable Announces Intent to Acquire Apex Security
Generative AI tools and autonomous systems are rapidly expanding the attack surface and introducing new risks — from shadow AI apps and AI-generated code to synthetic identities and ungoverned cloud services. In 2024, Tenable launched Tenable AI Aware which already helps thousands of organizations detect and assess AI usage across their environments. Adding Apex capabilities will expand on that foundation — adding the ability to govern usage, enforce policy, and control exposure across both the AI that organizations use and the AI they build. This move reinforces Tenable's long-standing strategy of delivering scalable, unified exposure management as AI adoption accelerates.
'AI dramatically expands the attack surface, introducing dynamic, fast-moving risks most organizations aren't prepared for,' said Steve Vintz, Co-CEO and CFO, Tenable. 'Tenable's strategy has always been to stay ahead of attack surface expansion — not just managing exposures, but eliminating them before they can be exploited.'
'As organizations move quickly to adopt AI, many recognize that now is the moment to get ahead of the risk — before large-scale attacks materialize,' said Mark Thurmond, Co-CEO, Tenable. 'Apex delivers the visibility, context, and control security teams need to reduce AI-generated exposure proactively. It will be a powerful addition to the Tenable One platform and a perfect fit for our preemptive approach to cybersecurity.'
Founded in 2023, Apex attracted early interest from CISOs and top investors, including Sam Altman (OpenAI), Clem Delangue (Hugging Face), and venture capital firms Sequoia Capital and Index Ventures. The company quickly emerged as an innovator in securing the use of AI by developers and everyday employees alike — addressing the growing need to manage usage, enforce policy, and ensure compliance at scale.
'The AI attack surface is deeply intertwined with everything else organizations are already securing. Treating it as part of exposure management is the most strategic approach. We're excited to join forces with Tenable to help customers manage AI risk in context — not as a silo, but as part of their broader environment,' said Matan Derman, CEO and Co-Founder of Apex Security.
Following the acquisition close, Tenable expects to deliver integrated capabilities in the second half of 2025 as part of Tenable One — the industry's first and most comprehensive exposure management platform. The financial terms of the deal were not disclosed. The deal is expected to close later this quarter. 0 0

Energy and Innovation summit: Trump says $92bn to be invested in Pennsylvania for AI and tech
US President Donald Trump pushed his vision on powering energy-hungry artificial intelligence, during the first Pennsylvania Energy and Innovation Summit. At a discussion on Tuesday, Mr Trump claimed that more than 20 technology and energy companies had decided to invest $92 billion in Pennsylvania. "This is really a triumphant day for the people of the Commonwealth," he told the event, led by Republican US Senator Dave McCormick, in Pittsburgh at Carnegie Mellon University. 'This summit is about catalysing $90 billion of investment and tens of thousands of jobs in Pennsylvania,' Mr McCormick said. He also referred to the increasingly adversarial relationship between the US and China as he set the stage for the day's agenda. 'If we don't lead this AI revolution on our own terms, we will hand control of our infrastructure, data, leadership and way of life to the Chinese Communist Party,' Mr McCormick said. With AI continuing to expand into all aspects of life, the burden it places on the US energy grid is becoming more of an issue, as policymakers try to keep America leading the global race for AI dominance. According to a report from the US Energy Department, data centres used about 4.4 per cent of total electricity in the country in 2024. By 2028, that share could increase to 12 per cent. By most estimates, a query to ChatGPT uses 10 times more energy than a similar search on Google. The event has featured panels and discussions on energy and AI, including how to best meet the energy needs created by the technology, and looking at the efficiencies that AI could create in the years ahead. There were also discussions about the need for data centres to keep up with the AI investment boom and increased user demand. During the opening panel discussion, alternative asset management firm Blackstone made a $25 billion investment in building data centres in Pennsylvania. Investors, entrepreneurs and business leaders from around the world are attending the event. Khaldoon Al Mubarak, Mubadala's managing director and chief executive and chairman of the UAE Executive Affairs Authority, made the trip to Pittsburgh. Lim Chow Kiat, chief executive of Singapore's Government Investment Corporation, was also invited. US Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick, Interior Secretary Doug Burgum and Energy Secretary Chris Wright were among the White House officials in attendance. Alex Karp, chief executive of AI firm Palantir, Joseph Dominguez, Constellation Energy chief, and Jake Loosararian, founder of Gecko Robotics, also took part. As proof of how bipartisan AI and energy issues have become, Pennsylvania's Democratic Governor Josh Shapiro, a staunch critic of Mr Trump and a possible contender for the 2028 Democratic presidential race, is scheduled to attend. For coal, fracking and even nuclear power, Pennsylvania has become the centre of the US energy renaissance. A few weeks ago, Mr Shapiro attended a nuclear energy rally to celebrate a partnership with Microsoft at the Three Mile Island nuclear power plant in the state, which will soon reopen under a different name. Nuclear energy is seen by many supporters of AI as a way to strengthen the energy grid as use of the technology expands. But critics fear the content of the event will be taken over by politics. A day before the event, Carnegie Mellon University's president, Farnam Jahanian, acknowledged the politically charged backdrop against which the conference was taking place. 'I recognise that CMU's decision to host the summit has prompted concern and disagreement among some members of our community,' Mr Jahanian said, pointing out his disagreements with Mr Trump on issues concerning education funding. 'At the same time, I firmly believe that higher education must be a convener – a catalyst for ideas and partnerships that shape our future.' On Tuesday, Mr Jahanian said CMU, with its roots in technology, was the perfect host for the summit, which was a 'defining moment for our country and humanity'. He said AI was 'the most important intellectual development of our time'.

Meta to invest ‘hundreds of billions' of dollars in advanced AI
Meta Platforms plans to invest hundreds of billions of dollars in computing infrastructure to advance its superintelligence ambitions in artificial intelligence (AI), according to Chief Executive Mark Zuckerberg. Writing on social media platform Threads, Zuckerberg said Meta would build one of the most 'elite and talent-dense teams in the industry' and had the capital from its business to support the plans. 'We're also going to invest hundreds of billions of dollars into compute to build superintelligence,' he said. Meta investing hundreds of billions in AI Superintelligence refers to a hypothetical AI system that is capable of outperforming the human brain. Zuckerberg unveiled plans for massive data centres to support the effort. One facility, called Prometheus, is expected to go online in 2026. Another, Hyperion, could eventually consume up to 5 gigawatts of power – enough to supply electricity to more than four million average US households, according to experts.

7 Hard Truths About Building AI Products That Last
For years, product innovation has been fueled by excitement: a new framework, a breakthrough model, a rising trend. But in 2025, as AI weaves itself into every interface, the question that separates good AI products from enduring ones isn't 'What can we build?'—it's 'What should we build?' According to the 2025 State of Martech Report by Scott Brinker, product management is now one of the most pivotal roles in the Martech ecosystem tasked with balancing rapid innovation, data complexity, and the promise (and pitfalls) of AI. As boundaries between product, marketing, and customer experience blur, the need for clarity, focus, and intentional design has never been greater. Because behind every buzzword, be it LLM, Web3, or genAI , is a simple truth: if it doesn't solve a real customer problem, it's noise. To ground this exploration, we turn to insights from Sumaiya Noor, Product, AI & Technology Leader, who has built B2B, B2C, and B2B2C SaaS products across emerging tech domains like AI and Web3. Drawing from her product, engineering, and customer experience background, Sumaiya offers a refreshingly pragmatic lens, one focused not on hype cycles, but on human problems. Strategy Can't Be Built in Silos In high-velocity environments, roadmaps shift, features morph, and priorities blur. So how do you keep AI product and marketing aligned ? The answer lies in dissolving the silos entirely. 'We don't build and then inform,' says Sumaiya. 'We build together.' Cross-functional planning, with inputs from sales, marketing, CX, and engineering, not only improves go-to-market timing, it ensures that every feature is designed with customer communication in mind. And yet, even with cross-functional harmony, another trap remains: building for the tech instead of the problem. That's where disciplined product thinking becomes essential. The Case for Problem-First Product Thinking There's a temptation to fall in love with an idea or worse, a technology. But as Sumaiya puts it: 'Even the best idea is irrelevant if no one will pay for it.' The most impactful products today aren't those that chase AI for the sake of AI. They start with deep listening. They define the problem before prescribing the tech. And only then do they decide whether that shiny new model is the right tool. But what happens when customer needs evolve faster than the solutions built to serve them? When Customer Pain Points Evolve Faster Than You Build Technology is changing rapidly but so are customer expectations. The feature they needed last month might feel redundant next week. This is where continuous product discovery becomes non-negotiable. Beta feedback, prototype testing, and agile pivots must be baked into the build process. 'It's not about being right from the start,' says Sumaiya. 'It's about being flexible enough to shift fast, based on what your users actually tell you.' Flexibility is key. Not just in building, but in knowing when to stop building. Because holding on to outdated features can be just as risky as launching the wrong ones. Sunsetting Isn't Failure, It's Focus Great teams know when to quit. That feature your team launched with pride may no longer serve its purpose—maybe a competitor has done it better, or your users have outgrown it. The hardest part? Internal buy-in. 'You're not just retiring code,' Sumaiya notes. 'You're sunsetting people's effort, pride, and belief.' But with clear metrics and shared goals, this becomes a strategic move, not an emotional one. And as AI becomes embedded in more features, another layer of complexity emerges: unpredictability. Especially when the tech behaves in ways even its creators can't fully control. You Can't Eliminate AI Hallucinations But You Can Contain Them As large language models make their way into every workflow, a difficult truth remains: hallucinations are part of the system. 'If someone in the product world says that hallucination can completely be eliminated or can be mitigated, I think they don't understand the technological side of LLMs or AI, artificial intelligence or agents that much,' says Sumaiya. Rather than over-promise, product teams must scope narrowly, train models on proprietary data, and design safeguards to guide behaviour. 'You can't fully control LLMs but you can control how, where, and why you deploy them.' But responsible deployment isn't enough. You also need to know if your AI is actually adding value, which brings us to the challenge of building effective feedback loops. Feedback Loops in AI Products Are Twice As Hard Feedback is already tough in traditional product development. In AI, it's even more layered. 'You need two types of feedback loops. One for validating the feature itself, the service itself, whatever you are trying to provide to the customer. In terms of solving their problem or pain point. If it's an AI integrated or AI-based product, the additional feedback loop is also required to validate what type of value addition this AI integration is adding to your overall solution,' says Sumaiya. You're not only asking whether a feature works, you're asking whether AI is meaningfully improving the experience. This means comparing pre- and post-AI metrics, collecting real-time usage data, and isolating AI's impact on usability and satisfaction. Even with feedback in place, product teams still face a difficult judgment call: which technologies are worth betting on, and which ones are just noise? How to Tell If a Technology Will Stick or Fizzle When everyone's chasing the next 'platform shift,' how do you know what's real? Sumaiya's take: measure cost (financial, environmental, ethical), problem-fit, and long-term sustainability. Her critique of blockchain coin mining, versus her long-term belief in AI, isn't about trendiness. It's about impact. 'Tech that creates more problems than it solves won't last.' In the end, it's not about resisting innovation. It's about choosing it wisely. In a world shaped by AI, what we build is only as good as why we build it.
