Tenable Holdings Inc

Tenable Holdings will replace Leggett & Platt in the S&P SmallCap 600, effective prior to the opening of trading on Monday, August 31. The index change follows the acquisition of Leggett & Platt by Somnigroup International, an S&P MidCap 400 constituent, in a deal expected to close soon. Tenable shares rose about 7% in extended trading on Wednesday.

New joint research from SentinelOne and Tenable finds that cyber attackers, including nation-state and criminal actors, are focusing on edge-device vendor ecosystems rather than individual vulnerabilities. The study, which combines Tenable's exposure data with SentinelOne's runtime detection, shows that exposure data and runtime detection converge on the same vendor surfaces 79% of the time, while sharing only 21% overlap at the individual vulnerability level. Twelve vulnerabilities in the dataset carry confirmed multi-nexus attribution, with state-sponsored and ransomware operators independently exploiting the same flaws across five threat categories, including China, Russia, DPRK, Iran-nexus, and criminal actors. More than half of organizations running F5 products have at least one exposed, actively exploited vulnerability, and Citrix customers take a median of 461 days to remediate, the slowest of any vendor studied. The research also highlights a statistically significant 24-day gap in remediation complexity, underscoring that patching speed alone is insufficient without attack surface minimization and endpoint protection.

Tenable Holdings announced that its Tenable One platform now covers every major AI platform and developer tool, adding Google Gemini to a list that already included Anthropic Claude, OpenAI's ChatGPT Enterprise, and Microsoft Copilot. The company detected 457 million AI-related security issues across more than 7,000 organizations, averaging 62,000 exposures per organization over 30 days. Tenable One AI Exposure now extends discovery to every major LLM, all major Model Context Protocol deployments, and AI-native development tools like Cursor, Windsurf, and Trae, roughly doubling its coverage of sanctioned and shadow AI in one release. Second-quarter revenue came in at $268.5 million, ahead of management's guided range of $263 million to $266 million, while operating expenses fell to $195.8 million from $200.3 million a year earlier, flipping a $14.7 million net loss into a $3.8 million net profit. The stock is up more than 40% in 2026, yet Tenable's market capitalization of $3.6 billion remains a fraction of CrowdStrike Holdings and Palo Alto Networks, whose combined market cap tops $450 billion.

Tenable Holdings exceeded second-quarter fiscal 2026 expectations and raised its full-year outlook, driven by record adoption of its Tenable One exposure management platform. Revenue reached $268.5 million, up 8.6% year-over-year, while non-GAAP earnings per share jumped to $0.51 from $0.34 a year earlier. The Tenable One platform accounted for 50% of new business, a milestone fueled by new pricing and packaging that saw customers favor the higher-priced Advanced tier. Net dollar expansion rate improved to 106%, its first acceleration since early 2022, and the company added 381 new enterprise customers along with 32 net new six-figure accounts. Full-year revenue guidance was raised to a range of $1.075 billion to $1.081 billion, and non-GAAP EPS guidance was lifted to $1.95 to $2.00, reflecting first-half momentum and share repurchases that totaled 5.2 million shares for $100 million in the quarter.

Tenable has enhanced its Tenable One Exposure Management Platform with new AI security capabilities that now cover Google Gemini, extending its reach across all major large language models including Anthropic Claude, OpenAI ChatGPT Enterprise, and Microsoft Copilot. The update also adds discovery for all major Model Context Protocol deployments and AI-native integrated development environment tools such as Cursor, Windsurf, and Trae. The company reported detecting 457 million AI-related security issues across more than 7,000 organizations in a 30-day period, averaging 62,000 exposures per organization. The platform now enables operationalized remediation through direct ticket creation in Jira and ServiceNow, as well as automated notifications via email, Slack, or Teams.

Tenable stock has soared by over 40% this year, but its market capitalization of just $3.6 billion remains a fraction of cybersecurity giants CrowdStrike and Palo Alto Networks, which have a combined market cap of over $450 billion. The company specializes in exposure management, a proactive form of enterprise protection that identifies vulnerabilities before attackers can exploit them, and demand is surging as hackers use AI to find weaknesses faster. Tenable generated $268.5 million in revenue during the second quarter, topping its forecast, and posted a net profit of $3.8 million compared to a $14.7 million loss a year earlier. Its price-to-sales ratio is just 3.7, a steep discount to its historical average of 7.1 and far below Palo Alto Networks' 22.9 and CrowdStrike's 38.1. The company's comprehensive Tenable One platform, powered by its Hexa AI engine, accounted for half of new sales in the quarter, signaling a shift toward its all-in-one solution.

Tenable Holdings raised its full-year 2026 revenue guidance to a range of $1.075 billion to $1.081 billion. The company also lifted its non-GAAP earnings per share outlook to $1.95 to $2.00 and its unlevered free cash flow forecast to $289 million to $295 million. For the second quarter, revenue reached $268.5 million, up 8.6% year-over-year, while non-GAAP earnings per share came in at $0.51. Tenable One accounted for a record 50% of new business during the quarter, up from 41% in the prior period, and the net dollar expansion rate improved to 106%. Management attributed the momentum to post-Mythos urgency, competitive displacements, and early adoption of the Hexa AI tool.

Tenable Holdings has launched always-on agentic fleet capabilities for its Hexa AI within the Tenable One Exposure Management Platform, introducing autonomous exposure remediation and risk reduction. The update unifies application security risks, including those tied to generative AI usage, and provides code-to-runtime visibility with a single risk context across multiple security domains. Tenable is traded on Nasdaq under the symbol TENB, with shares around $31.37, up 38.0% year to date but down 36.2% over three years. The new AI-driven capabilities aim to position Tenable around exposure management, code security, and generative AI-related risks, potentially influencing customer decisions on tool consolidation and automated remediation.

Tenable has launched Tenable Hexa AI, an agentic AI technology that slashes cybersecurity task times from weeks to mere seconds. Jason Merrick, Senior Vice President of Product Management at Tenable, said in an exclusive interview with Money & Banking Magazine that Tenable Hexa AI acts as a force multiplier for security teams, allowing organizations to use ready-made agents or build custom workflows to rapidly detect vulnerabilities and close risks from open-source usage. Additionally, Tenable offers the Tenable One platform, a unified risk management system that aggregates vulnerability data across IT, cloud, identity, web applications, operational technology, and open source, enriching it with deep context to prioritize and clearly communicate risks to executives. Jason emphasized that modern cybersecurity must link technical weaknesses to business impact, and combining Tenable One with Tenable Hexa AI will help organizations efficiently shift from reactive defense to proactive risk reduction.

Tenable Holdings announced that its Tenable One Cloud Exposure platform has achieved FedRAMP High and Impact Level 5 authorization, enabling the company to support highly sensitive U.S. federal, defense and intelligence environments. This certification deepens Tenable's access to mission-critical government workloads and strengthens its position with public-sector customers requiring rigorous cloud security assurances. The authorization could reinforce a near-term federal growth catalyst by opening more sensitive workloads to Tenable, though it also heightens the risk that a slowdown in U.S. public sector spending could weigh on results. The announcement follows Tenable's recent involvement with OpenAI through the Daybreak Cyber Partner Program, both developments underscoring efforts to deepen value in complex, high-stakes environments.

JPMorgan analyst Brian Essex raised his price target on Tenable to $40 from $35 while maintaining an overweight rating and adding the stock to the firm's Analyst Focus List. Essex cited expectations that threats from China will continue to drive demand for Tenable's cybersecurity solutions and sees the company as the best-positioned exposure management vendor to address escalating threats. The new target implies a 19.4% upside from yesterday's close of $33.49. The move follows Tenable's announcement that it achieved FedRAMP High and Impact Level 5 authorization from the U.S. government, making it eligible for federal cloud contracts with stringent security requirements. Shares of Tenable rose 7% in morning trading, extending an 11% gain from the previous session.

Shares of Palo Alto Networks and Tenable jumped sharply after the United States and Iran agreed to halt military exchanges, easing fears of a wider Middle East conflict. Palo Alto Networks rose 8.4 percent and Tenable gained 7.7 percent as the de-escalation removed a macro overhang that had pressured high-multiple growth software stocks. Lower oil prices eased inflation concerns, reducing expectations for a Federal Reserve rate hike, which disproportionately benefits long-duration software companies. The rally was also supported by a chip-to-software rotation triggered by a report that OpenAI may delay its IPO, softening fears that AI labs would quickly disrupt incumbent SaaS firms. Palo Alto Networks shares have now risen 83.7 percent year-to-date, reaching a new 52-week high of 329.48 dollars.
