Cybersecurity professionals under pressure turn to AI amid rising threats

Published

on



Good morning. Cyberattacks are a top concern for CFOs. However, cybersecurity professionals are feeling increased stress due to the complexity of the threat landscape and ongoing risks.

In a new report shared with CFO Daily, ISACA—a global association for IT governance, security, risk, and audit professionals—surveyed more than 3,800 cybersecurity experts. Two-thirds said their roles are more stressful than five years ago, and 63% named the complexity of today’s landscape as the top stressor. Nearly half (47%) cited high stress as the primary reason for attrition.

The survey found that 43% of respondents believe an attack on their organization is likely in the next year, yet just 41% are confident in their teams’ incident-response capabilities. Additionally, 39% believe cybercrime is underreported, even when reporting is required.

The most common type of attack is social engineering (44%)—manipulation techniques that trick individuals into giving up confidential information—followed by 37% who noted exploited vulnerabilities (flaws or weaknesses in software, hardware, or network systems) and 36% said malware (malicious software or code). About one-third of cybersecurity professionals still reported an increase in incidents this year, according to the report.

“Cybersecurity professionals are navigating an increasingly complex threat landscape, marked by the rapid evolution of threats and an increase in both the frequency and sophistication of attacks,” Chris McGowan, ISACA principal for information security professional practices, said in a statement.

McGowan noted an anticipated rise in cyberattacks next year would put even more pressure on cybersecurity teams, emphasizing the importance of regularly reviewing support systems and training to strengthen skills and resilience. Companies must not only improve their defenses, but also prioritize the well-being of their cybersecurity teams, he added.

The stress is worsened by persistent understaffing, with 55% of cybersecurity teams short-staffed and 65% having unfilled roles. Fewer organizations are training non-security staff to move into cybersecurity positions.

Turning to AI for defense

“AI has proven valuable in strengthening defenses,” according to Aparna Achanta, a security leader at IBM Consulting. Machine learning helps detect anomalies at scale, while automation reduces analysts’ workload by triaging alerts and speeding up responses, Achanta told ISACA. 

Meanwhile, predictive models highlight attack risks, and in security operations centers, AI improves event correlation and investigation, she said. Experts caution that human oversight is needed to avoid bias, blind spots, and errors in decision-making, Achanta added.

Respondents report increased use of AI in their work and a larger role in AI policy at their organizations. Almost half (47%) said they helped develop AI governance practices (up from 35% last year), and 40% were involved in AI implementation (up from 29%). The top uses of AI in security operations are threat detection, endpoint security, and automating routine tasks.

In cybersecurity, adaptation isn’t optional—it’s survival.

Naveen Kumar Amar was appointed CFO of SS Innovations International, Inc. (Nasdaq: SSII), a surgical robotic technologies provider, effective Sept. 24. Amar replaces Vishwa Srivastava, who has served as the company’s interim CFO since July 2025. Srivastava will continue in his capacity as the CEO—Asia Pacific. Amar brings to SS Innovations more than 25 years of global finance leadership experience. 

Big Deal

CFOs are turning volatility into growth in working capital, according to new research by Visa. The company’s third annual Growth Corporates Working Capital Index draws on insights from more than 1,400 CFOs and treasurers globally at mid-sized firms—defined as companies with annual revenues between $50 million and $1 billion.

Modern CFOs and treasurers are proactively using working capital to unlock trapped cash, pursue market opportunities, and invest in strategic initiatives, even in uncertain economic times, according to Ben Ellis, global head of large and middle markets for Visa Commercial Solutions.

“This shift means that instead of letting resources sit idle, companies leverage solutions like faster supplier payments, inventory optimization, and better payment terms to generate additional value and support growth,” Ellis told CFO Daily. When managed with modern tools and strategies, working capital directly contributes to operational efficiency, agility, and expansion, making it a key driver of business growth.

The CFOs and treasurers surveyed fall into two categories: adaptable accelerators—who use working capital solutions to manage volatility—and strategic planners—who see working capital as a tool for expansion. Strategic planners focus on growth and investment, rather than just covering short-term cash gaps, Ellis explained. 

The data show that this approach results in higher operational efficiency, greater supplier integration, improved liquidity, and enhanced resilience during volatility. “Organizations led by strategic planners consistently outperform their peers in these areas, making them better positioned to drive sustained value,” he said.

Going deeper

The two startups, Kalshi and Polymarket, generated huge buzz by accurately predicting the 2024 election results. However, their young founders still face long odds. “‘Investors are betting big on prediction markets Kalshi and Polymarket—will the gamble pay off?’” a new Fortune feature article by Jeff John Roberts offers a deep dive into why investors are backing these companies.

“The biggest risk hanging over the industry is a basic business question: Can sites like Kalshi and Polymarket generate sustained interest—and revenue—outside of the once-in-four-years presidential contest?” Roberts writes.

Overheard

“AI isn’t just another tool to optimize today’s workflows. It’s a force multiplier that rewrites what problems are even worth solving.”

—Mike Hoffman, the chief executive officer of the growth advisory, SBI, writes in a Fortune opinion piece. “Right now, CEOs are both bullish and anxious. Some are hiring for AI-powered roles,” Hoffman explains. “Others are cutting headcount in anticipation of efficiency gains. Some are doing both. This is understandable, but it misses the bigger picture.”

Senate Dems’ plan to fix Obamacare premiums adds nearly $300 billion to deficit, CRFB says

Published

on



The Committee for a Responsible Federal Budget (CRFB) is a nonpartisan watchdog that regularly estimates how much the U.S. Congress is adding to the $38 trillion national debt.

With enhanced Affordable Care Act (ACA) subsidies due to expire within days, some Senate Democrats are scrambling to protect millions of Americans from getting the unpleasant holiday gift of spiking health insurance premiums. The CRFB says there’s just one problem with the plan: It’s not funded.

“With the national debt as large as the economy and interest payments costing $1 trillion annually, it is absurd to suggest adding hundreds of billions more to the debt,” CRFB President Maya MacGuineas wrote in a statement on Friday afternoon.

The proposal, backed by members of the Senate Democratic caucus, would fully extend the enhanced ACA subsidies for three years, from 2026 through 2028, with no additional income limits on who can qualify. Those subsidies, originally boosted during the pandemic and later renewed, were designed to lower premiums and prevent coverage losses for middle‑ and lower‑income households purchasing insurance on the ACA exchanges.

CRFB estimated that even this three‑year extension alone would add roughly $300 billion to federal deficits over the next decade, largely because the federal government would continue to shoulder a larger share of premium costs while enrollment and subsidy amounts remain elevated. If Congress ultimately moves to make the enhanced subsidies permanent—as many advocates have urged—the total cost could swell to nearly $550 billion in additional borrowing over the next decade.

Reversing recent guardrails

MacGuineas called the Senate bill “far worse than even a debt-financed extension” as it would roll back several “program integrity” measures that were enacted as part of a 2025 reconciliation law and were intended to tighten oversight of ACA subsidies. On top of that, it would be funded by borrowing even more. “This is a bad idea made worse,” MacGuineas added.

The watchdog group’s central critique is that the new Senate plan does not attempt to offset its costs through spending cuts or new revenue and, in their view, goes beyond a simple extension by expanding the underlying subsidy structure.

The legislation would permanently repeal restrictions that eliminated subsidies for certain groups enrolling during special enrollment periods and would scrap rules requiring full repayment of excess advance subsidies and stricter verification of eligibility and tax reconciliation. The bill would also nullify portions of a 2025 federal regulation that loosened limits on the actuarial value of exchange plans and altered how subsidies are calculated, effectively reshaping how generous plans can be and how federal support is determined. CRFB warned these reversals would increase costs further while weakening safeguards designed to reduce misuse and error in the subsidy system.

MacGuineas said that any subsidy extension should be paired with broader reforms to curb health spending and reduce overall borrowing. In her view, lawmakers are missing a chance to redesign ACA support in a way that lowers premiums while also improving the long‑term budget outlook.

The debate over ACA subsidies recently contributed to a government funding standoff, and CRFB argued that the new Senate bill reflects a political compromise that prioritizes short‑term relief over long‑term fiscal responsibility.

“After a pointless government shutdown over this issue, it is beyond disappointing that this is the preferred solution to such an important issue,” MacGuineas wrote.

The off-year elections cast the government shutdown and cost-of-living arguments in a different light. Democrats made stunning gains and almost flipped a deep-red district in Tennessee as politicians from the far left and center coalesced around “affordability.”

Senate Minority Leader Chuck Schumer is reportedly smelling blood in the water and doubling down on the theme heading into the pivotal midterm elections of 2026. President Donald Trump is scheduled to visit Pennsylvania soon to discuss pocketbook anxieties. But he is repeating predecessor Joe Biden’s habit of dismissing inflation, despite widespread evidence to the contrary.

“We fixed inflation, and we fixed almost everything,” Trump said in a Tuesday cabinet meeting, in which he also dismissed affordability as a “hoax” pushed by Democrats.​

Lawmakers on both sides of the aisle now face a politically fraught choice: allow premiums to jump sharply—including in swing states like Pennsylvania where ACA enrollees face double‑digit increases—or pass an expensive subsidy extension that would, as CRFB calculates, explode the deficit without addressing underlying health care costs.

Netflix–Warner Bros. deal sets up $72 billion antitrust test

Published

on



Netflix Inc. has won the heated takeover battle for Warner Bros. Discovery Inc. Now it must convince global antitrust regulators that the deal won’t give it an illegal advantage in the streaming market. 

The $72 billion tie-up joins the world’s dominant paid streaming service with one of Hollywood’s most iconic movie studios. It would reshape the market for online video content by combining the No. 1 streaming player with the No. 4 service HBO Max and its blockbuster hits such as Game Of ThronesFriends, and the DC Universe comics characters franchise.  

That could raise red flags for global antitrust regulators over concerns that Netflix would have too much control over the streaming market. The company faces a lengthy Justice Department review and a possible US lawsuit seeking to block the deal if it doesn’t adopt some remedies to get it cleared, analysts said.

“Netflix will have an uphill climb unless it agrees to divest HBO Max as well as additional behavioral commitments — particularly on licensing content,” said Bloomberg Intelligence analyst Jennifer Rie. “The streaming overlap is significant,” she added, saying the argument that “the market should be viewed more broadly is a tough one to win.”

By choosing Netflix, Warner Bros. has jilted another bidder, Paramount Skydance Corp., a move that risks touching off a political battle in Washington. Paramount is backed by the world’s second-richest man, Larry Ellison, and his son, David Ellison, and the company has touted their longstanding close ties to President Donald Trump. Their acquisition of Paramount, which closed in August, has won public praise from Trump. 

Comcast Corp. also made a bid for Warner Bros., looking to merge it with its NBCUniversal division.

The Justice Department’s antitrust division, which would review the transaction in the US, could argue that the deal is illegal on its face because the combined market share would put Netflix well over a 30% threshold.

The White House, the Justice Department and Comcast didn’t immediately respond to requests for comment. 

US lawmakers from both parties, including Republican Representative Darrell Issa and Democratic Senator Elizabeth Warren have already faulted the transaction — which would create a global streaming giant with 450 million users — as harmful to consumers.

“This deal looks like an anti-monopoly nightmare,” Warren said after the Netflix announcement. Utah Senator Mike Lee, a Republican, said in a social media post earlier this week that a Warner Bros.-Netflix tie-up would raise more serious competition questions “than any transaction I’ve seen in about a decade.”

European Union regulators are also likely to subject the Netflix proposal to an intensive review amid pressure from legislators. In the UK, the deal has already drawn scrutiny before the announcement, with House of Lords member Baroness Luciana Berger pressing the government on how the transaction would impact competition and consumer prices.

The combined company could raise prices and broadly impact “culture, film, cinemas and theater releases,”said Andreas Schwab, a leading member of the European Parliament on competition issues, after the announcement.

Paramount has sought to frame the Netflix deal as a non-starter. “The simple truth is that a deal with Netflix as the buyer likely will never close, due to antitrust and regulatory challenges in the United States and in most jurisdictions abroad,” Paramount’s antitrust lawyers wrote to their counterparts at Warner Bros. on Dec. 1.

Appealing directly to Trump could help Netflix avoid intense antitrust scrutiny, New Street Research’s Blair Levin wrote in a note on Friday. Levin said it’s possible that Trump could come to see the benefit of switching from a pro-Paramount position to a pro-Netflix position. “And if he does so, we believe the DOJ will follow suit,” Levin wrote.

Netflix co-Chief Executive Officer Ted Sarandos had dinner with Trump at the president’s Mar-a-Lago resort in Florida last December, a move other CEOs made after the election in order to win over the administration. In a call with investors Friday morning, Sarandos said that he’s “highly confident in the regulatory process,” contending the deal favors consumers, workers and innovation. 

“Our plans here are to work really closely with all the appropriate governments and regulators, but really confident that we’re going to get all the necessary approvals that we need,” he said.

Netflix will likely argue to regulators that other video services such as Google’s YouTube and ByteDance Ltd.’s TikTok should be included in any analysis of the market, which would dramatically shrink the company’s perceived dominance.

The US Federal Communications Commission, which regulates the transfer of broadcast-TV licenses, isn’t expected to play a role in the deal, as neither hold such licenses. Warner Bros. plans to spin off its cable TV division, which includes channels such as CNN, TBS and TNT, before the sale.

Even if antitrust reviews just focus on streaming, Netflix believes it will ultimately prevail, pointing to Amazon.com Inc.’s Prime and Walt Disney Co. as other major competitors, according to people familiar with the company’s thinking. 

Netflix is expected to argue that more than 75% of HBO Max subscribers already subscribe to Netflix, making them complementary offerings rather than competitors, said the people, who asked not to be named discussing confidential deliberations. The company is expected to make the case that reducing its content costs through owning Warner Bros., eliminating redundant back-end technology and bundling Netflix with Max will yield lower prices.

The rise of AI reasoning models comes with a big energy tradeoff

Published

on



Nearly all leading artificial intelligence developers are focused on building AI models that mimic the way humans reason, but new research shows these cutting-edge systems can be far more energy intensive, adding to concerns about AI’s strain on power grids.

AI reasoning models used 30 times more power on average to respond to 1,000 written prompts than alternatives without this reasoning capability or which had it disabled, according to a study released Thursday. The work was carried out by the AI Energy Score project, led by Hugging Face research scientist Sasha Luccioni and Salesforce Inc. head of AI sustainability Boris Gamazaychikov.

The researchers evaluated 40 open, freely available AI models, including software from OpenAI, Alphabet Inc.’s Google and Microsoft Corp. Some models were found to have a much wider disparity in energy consumption, including one from Chinese upstart DeepSeek. A slimmed-down version of DeepSeek’s R1 model used just 50 watt hours to respond to the prompts when reasoning was turned off, or about as much power as is needed to run a 50 watt lightbulb for an hour. With the reasoning feature enabled, the same model required 7,626 watt hours to complete the tasks.

The soaring energy needs of AI have increasingly come under scrutiny. As tech companies race to build more and bigger data centers to support AI, industry watchers have raised concerns about straining power grids and raising energy costs for consumers. A Bloomberg investigation in September found that wholesale electricity prices rose as much as 267% over the past five years in areas near data centers. There are also environmental drawbacks, as Microsoft, Google and Amazon.com Inc. have previously acknowledged the data center buildout could complicate their long-term climate objectives

More than a year ago, OpenAI released its first reasoning model, called o1. Where its prior software replied almost instantly to queries, o1 spent more time computing an answer before responding. Many other AI companies have since released similar systems, with the goal of solving more complex multistep problems for fields like science, math and coding.

Though reasoning systems have quickly become the industry norm for carrying out more complicated tasks, there has been little research into their energy demands. Much of the increase in power consumption is due to reasoning models generating much more text when responding, the researchers said. 

The new report aims to better understand how AI energy needs are evolving, Luccioni said. She also hopes it helps people better understand that there are different types of AI models suited to different actions. Not every query requires tapping the most computationally intensive AI reasoning systems.

“We should be smarter about the way that we use AI,” Luccioni said. “Choosing the right model for the right task is important.”

To test the difference in power use, the researchers ran all the models on the same computer hardware. They used the same prompts for each, ranging from simple questions — such as asking which team won the Super Bowl in a particular year — to more complex math problems. They also used a software tool called CodeCarbon to track how much energy was being consumed in real time.

The results varied considerably. The researchers found one of Microsoft’s Phi 4 reasoning models used 9,462 watt hours with reasoning turned on, compared with about 18 watt hours with it off. OpenAI’s largest gpt-oss model, meanwhile, had a less stark difference. It used 8,504 watt hours with reasoning on the most computationally intensive “high” setting and 5,313 watt hours with the setting turned down to “low.” 

OpenAI, Microsoft, Google and DeepSeek did not immediately respond to a request for comment.

Google released internal research in August that estimated the median text prompt for its Gemini AI service used 0.24 watt-hours of energy, roughly equal to watching TV for less than nine seconds. Google said that figure was “substantially lower than many public estimates.” 

Much of the discussion about AI power consumption has focused on large-scale facilities set up to train artificial intelligence systems. Increasingly, however, tech firms are shifting more resources to inference, or the process of running AI systems after they’ve been trained. The push toward reasoning models is a big piece of that as these systems are more reliant on inference.

Recently, some tech leaders have acknowledged that AI’s power draw needs to be reckoned with. Microsoft CEO Satya Nadella said the industry must earn the “social permission to consume energy” for AI data centers in a November interview. To do that, he argued tech must use AI to do good and foster broad economic growth.
