Three cybersecurity deals that would make sense as AI resets the market
Big security platforms are buying fast, and a few well-known independent companies look like logical next targets.
Analysis, not news. These are possible deals our editors think would make sense, based on public information. None has been announced, and most may never happen. Not investment advice.
Cybersecurity deals are running at record levels. Google closed its $32 billion Wiz purchase, Palo Alto Networks closed its $25 billion CyberArk deal, ServiceNow closed Armis for $7.75 billion, and Accenture agreed in June to pay $4.175 billion for Dragos, runZero and NetRise. Buyers are racing to add AI security and exposure-management tools before rivals do. Meanwhile, smaller independent vendors are cutting costs and dealing with activist investors. Below are three pairings that would make strategic sense. None has been announced. This is our analysis, not news.
1. Check Point Software Technologies → Tenable
Why Check Point could make a play for Tenable
Under CEO Nadav Zafrir, Check Point has organised its strategy around four pillars: network, workspace, exposure management and AI security. Exposure management is the pillar where it has relied most on small purchases. This year it bought the Israeli startups Cyata, Cyclops and Rotate, which Globes estimated at more than $150 million combined, and then Deepchecks, adding to the Lakera and Veriti deals from 2025. Tenable calls itself 'the exposure management company.' It is adding AI coverage too, including its Apex Security acquisition and its recent work with OpenAI's GPT cyber models. Buying Tenable would hand Check Point, a company with roughly $2.7 billion in revenue, an established exposure-management franchise instead of piecing one together from startups.
What stands in the way: So far Check Point has bought startups rather than public companies, and a full takeover of Tenable would be a much bigger bet than anything it has done under Zafrir. Fitting a Maryland-based public company into an Israeli-run platform would also be a real cultural and integration challenge.

2. Palo Alto Networks → SentinelOne
Why Palo Alto Networks could take another look at SentinelOne
Palo Alto has been the sector's most aggressive consolidator, closing its $25 billion CyberArk acquisition in February. SentinelOne has been reported as a target before: in July 2025, SDxCentral cited a CTech report of industry rumours that the two companies were in advanced talks, valuing SentinelOne at $8 billion to $10 billion. Since then, SentinelOne has added AI-native assets, buying Prompt Security for generative and agentic AI security and Observo for AI-ready data pipelines feeding its SIEM business. Those are the same areas where platform buyers are competing hardest.
What stands in the way: SentinelOne's filings say a change of control would make its unpaid Israeli tax installments, plus interest, come due. The company also completed a $1.25 billion convertible note offering this month, which suggests it is preparing to stay independent. Regulators have also shown concern about big security tie-ups, as the DOJ's review of Google-Wiz showed.
3. Accenture → Qualys
Why Accenture could make a play for Qualys
Accenture's $4.175 billion agreement for Dragos, runZero and NetRise showed that the consulting giant is willing to own security software products, not just resell them. runZero, which maps an organisation's assets and exposures, fits closely with Qualys's core vulnerability and compliance management business. Qualys is profitable and steady. It recently raised its full-year 2026 revenue guidance to $721–727 million, or 8% to 9% growth, which would give Accenture a recurring-revenue platform to sell into its consulting client base. Qualys is also known to be open to offers: in 2024 it was reported to be exploring options, including a sale, after receiving takeover interest.
What stands in the way: Qualys would be a much larger purchase than Accenture's June deals. And a services firm that owns a major security product could worry clients who value Accenture's vendor-neutral advice. Qualys's own 2024 review also ended without a deal, so its board may want a high price.
