Track market-moving stories before they get noisy

COLUMBIA, Md., Aug. 31, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced that it has joined Project Watershed, a White House-led initiative focused on protecting U.S. water and wastewater systems from cyber threats. Tenable brings expertise in helping organizations unify visibility, including across IT and OT security domains, prioritize risk and automate remediation to keep pace with evolving threats related to cyber exposures in the agentic AI era.

Led by the Office of the National Cyber Director (ONCD) and being piloted in Texas, Project Watershed connects participating water utilities with cybersecurity capabilities and expertise to help identify and address vulnerabilities. The initiative brings together federal and state leaders and private sector partners as part of the administration’s broader focus on protecting U.S. critical infrastructure and helping operators prevent cyber threats from disrupting essential services.

Tenable Public Sector Chief Technology Officer Chris Day joined National Cyber Director Sean Cairncross, Texas Governor Greg Abbott, Texas Cyber Command Chief Timothy James “TJ” White and private sector cybersecurity leaders at the Project Watershed event at the Texas Cyber Command Headquarters in San Antonio. The effort comes at a critical time for the water sector, following a series of cyberattacks affecting water and wastewater systems across multiple states. These incidents demonstrate how cyber risk can translate into operational consequences for the essential services communities depend on every day.

Water utilities face distinct challenges in managing this risk. Systems vary widely in size, resources and cybersecurity maturity, while many operators must secure increasingly interconnected information technology (IT) and operational technology (OT) environments. Greater visibility across these environments can help participating utilities identify their most consequential exposures and focus limited resources on risks that could have the greatest impact on critical operations.

“Protecting the water systems Americans rely on every day is a shared responsibility,” said Tenable’s Day. “We applaud the administration and Texas leaders for taking action and bringing the right expertise to the table. Tenable is proud to support this effort and help water operators get ahead of cyber risk and manage exposures before they lead to disruption.”

Tenable now delivers greater risk visibility and governance across an expanded AI attack surface created by increased adoption of LLMs, MCPs and AI tools August 04, 2026 09:00 ET  | Source: Tenable Holdings, Inc.

LAS VEGAS, Aug. 04, 2026 (GLOBE NEWSWIRE) -- Black Hat USA Booth #2639 — Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced enhanced AI security capabilities within the Tenable One Exposure Management Platform. Tenable One AI Exposure now delivers expanded platform coverage with support for Google Gemini, extending its coverage across major LLMs: Google Gemini, Anthropic Claude, OpenAI ChatGPT Enterprise and Microsoft Copilot. The release also extends discovery to all major Model Context Protocol (MCP) deployments and AI-native Integrated Development Environment (IDE) tools. Together, these capabilities give security teams a more complete view of where AI is being used, what risk it creates and where action is needed.

The rapid adoption of AI across the enterprise has created a critical AI exposure gap, a largely invisible risk that emerges across interconnected applications, infrastructure, identities and data. Underscoring this risk, Tenable detected 457 million AI-related security issues across more than 7,000 organizations, averaging 62,000 exposures per organization over a 30-day period. Traditional security tools leave security teams blind to high-impact attack paths, forcing them into a reactive loop rather than preemptively reducing AI risk.

Tenable One continuously discovers AI across endpoints, cloud and LLM applications, including both authorized and shadow AI. It inventories AI assets with the Tenable Exposure Graph, Tenable's data lake that aggregates massive volumes of security data to help organizations map, analyze and prevent cyber risks. Tenable One reduces real-world AI risk by securing the environments where AI runs and hardening AI workloads before they can be exploited. With these new advancements, Tenable One enables organizations to gain better visibility, context and control to manage AI risk while being able to govern AI use, enforce policies and prevent cyber exposures.

New AI security capabilities within Tenable One include:

Google Gemini Coverage: Tenable One now delivers visibility and governance for Google Gemini including monitoring of user interactions and prompt responses, policy enforcement, and detection of malicious activity and inappropriate usage.Enhanced AI Visibility: Tenable One now doubles its coverage of sanctioned and shadow AI, supporting MCPs, AI-native IDEs (such as Cursor, Windsurf and Trae) and AI-enabled browser extensions.Operationalized Remediation: Organizations can remediate faster by creating tickets directly in Jira and ServiceNow or alerting users on policy violations by sending automated email notifications, Slack or Teams messages. “The massive volume of AI exposures confirms the operational reality that authorized and unauthorized AI is deployed faster than security teams can govern it,” said Eric Doerr, Chief Product Officer, Tenable. “There’s no denying that AI attack surfaces are making defenders’ jobs even harder, and legacy or siloed cybersecurity tools simply don’t cut it. With today’s expansion to include Google Gemini, MCP and AI-native IDE deployments, Tenable is the only exposure management platform delivering unified AI visibility and governance across all major LLMs, software, and tools.”

Tenable One brings together two distinct AI capabilities. Tenable AI Exposure helps organizations discover, assess and secure how AI is being used across their environments. Tenable Hexa AI is the platform’s agentic engine, using AI to coordinate agents, automate security tasks and accelerate remediation. Put simply, AI Exposure helps organizations secure their use of AI, while Hexa helps them use AI to improve security operations. Together, they advance Tenable’s preemptive security strategy by helping organizations reduce AI-related risk and act on cyber exposure more efficiently.

Visit the Tenable booth #2639 this week at Black Hat USA, August 4-7, 2026, to see Tenable One in action.

Forward-Looking Statements

This press release includes forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. All statements contained in this press release other than statements of historical fact, including statements regarding our future results of operations and financial position, the ability of our partnerships with Anthropic and OpenAI to help drive new research, strengthen the security and capabilities of Tenable and help customers understand how frontier AI models behave, our ability to help transform threat investigations into precise remediation action, our business strategy, market opportunity and plans and objectives for future operations, are forward-looking statements and represent our views as of the date of this press release. The words “anticipate,” "believe,” “continue,” “estimate,” “expect,” “intend,” “may,” “will” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives and financial needs. These forward-looking statements are subject to a number of assumptions and risks and uncertainties, many of which involve factors or circumstances that are beyond our control that could affect our financial results. These risks and uncertainties are detailed in the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2025 and other filings that we make from time to time with the SEC, which are available on the SEC's website at sec.gov. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this press release may not occur and actual results could differ materially and adversely from those anticipated or implied in any forward-looking statements. Except as required by law, we are under no obligation to update these forward-looking statements subsequent to the date of this press release, or to update the reasons if actual results differ materially from those anticipated in the forward-looking statements.

Non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use certain non-GAAP financial measures, as described below, to understand and evaluate our core operating performance. These non-GAAP financial measures, which may be different than similarly titled measures used by other companies, are presented to enhance the overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We believe that these non-GAAP financial measures provide useful information about our financial performance, enhance the overall understanding of our past performance and future prospects and are helpful to investors in comparing our financial results over multiple periods with other companies in our industry.

Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the financial tables accompanying this press release.

Free Cash Flow and Unlevered Free Cash Flow: We define free cash flow, a non-GAAP financial measure, as net cash provided by operating activities less purchases of property and equipment and capitalized software development costs. We believe free cash flow is an important liquidity measure of the cash that is available (if any), after purchases of property and equipment and capitalized software development costs, for investment in our business and to make acquisitions. We believe that free cash flow is useful as a liquidity measure because it measures our ability to generate cash. We define unlevered free cash flow as free cash flow plus cash paid for interest and other financing costs. We believe unlevered free cash flow is useful as a liquidity measure as it measures the cash that is available to invest in our business and meet our current debt obligations and future financing needs. However, given our debt obligations, non-cancelable commitments and other contractual obligations, unlevered free cash flow does not represent residual cash flow available for discretionary expenses.

Non-GAAP Income from Operations and Non-GAAP Operating Margin: We define these non-GAAP financial measures as their respective GAAP measures, excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses, costs related to the intra-entity asset transfers resulting from the internal restructuring of legal entities, and amortization of acquired intangible assets. Acquisition-related expenses include transaction and integration expenses, as well as costs related to the intercompany transfer of acquired intellectual property. Restructuring expenses include non-ordinary course severance, employee related benefits, and other charges to reorganize business operations. We believe that the exclusion of these expenses provides for a useful comparison of our operating results to prior periods and to our peer companies, which commonly exclude restructuring expenses.

Non-GAAP Net Income and Non-GAAP Earnings Per Share: We define non-GAAP net income as GAAP net income (loss), excluding the effect of stock-based compensation, acquisition-related expenses, restructuring expenses and amortization of acquired intangible assets, including the applicable tax impacts. In addition, we exclude the tax impact and related costs of intra-entity asset transfers resulting from the internal restructuring of legal entities as well as deferred income tax benefits recognized in connection with acquisitions. We use non-GAAP net income to calculate non-GAAP earnings per share.

Non-GAAP Gross Profit and Non-GAAP Gross Margin: We define non-GAAP gross profit as GAAP gross profit, excluding the effect of stock-based compensation and amortization of acquired intangible assets. Non-GAAP gross margin is defined as non-GAAP gross profit as a percentage of revenue.

Non-GAAP Sales and Marketing Expense, Non-GAAP Research and Development Expense and Non-GAAP General and Administrative Expense: We define these non-GAAP measures as their respective GAAP measures, excluding stock-based compensation, acquisition-related expenses and costs related to intra-entity asset transfers resulting from the internal restructuring of legal entities.

Key Takeaways Tenable is using Hexa AI to automate risk triage and remediation across exposure management workflows. TENB is expanding Tenable One with cloud, identity, OT security and 300 pre-built integrations.TENB partners with OpenAI and Anthropic while proving AI advantages can drive sustained growth. Tenable Holdings (TENB - Free Report) sits near the center of a cybersecurity shift shaped by artificial intelligence. As AI accelerates vulnerability discovery and shortens the time between exposure and exploit, enterprises need faster ways to identify, prioritize and remediate risk.

That backdrop supports demand for unified exposure management. TENB’s challenge is turning that trend into durable product differentiation, sustained execution and better stock performance.

Tenable Benefits From a Faster Threat CycleAI is changing the pace of cyber defense. Frontier models are making vulnerability discovery faster, increasing pressure on security teams that already manage sprawling IT, cloud, identity and operational technology environments.

That urgency supports platforms that unify visibility, context and action. Narrow point products may still solve specific problems, but exposure management becomes more valuable when buyers need to understand which risks matter most and how quickly they can be fixed.

The competitive field is broad. Qualys (QLYS - Free Report) and Rapid7 (RPD - Free Report) remain relevant vulnerability management peers, while CrowdStrike, Palo Alto Networks (PANW - Free Report) and Wiz compete from adjacent areas such as endpoint and cloud security. That peer set underscores why TENB must keep expanding beyond traditional vulnerability scanning.

TENB Uses Hexa AI to Deepen Platform ValueTenable’s AI strategy centers on automation. Hexa AI is positioned as an agentic orchestration engine designed to automate triage and remediation workflows, helping turn exposure intelligence into action at machine speed.

That matters because buyers are not just looking for more alerts. They need systems that can prioritize risks and accelerate response. Hexa AI’s tiered packaging is also expected to support higher average selling prices over time.

Flex pricing adds another adoption lever. By simplifying per-asset procurement, Flex pricing may reduce friction as customers expand their exposure management footprint.

Qualys and Rapid7 are natural comparison points because security buyers often evaluate vulnerability management platforms against each other. TENB’s task is to show that Hexa AI and Tenable One create a broader operating model rather than simply adding another AI feature.

Tenable Pushes Into Cloud, Identity and OTPlatform convergence is central to the TENB story. Tenable One combines vulnerability management with cloud security, identity exposure, operational technology security, web app scanning and attack surface management.

That breadth gives TENB a wider role across modern attack surfaces. The company has also added native operational technology discovery capabilities, extending visibility into cyber-physical systems without additional hardware.

Recent milestones strengthen that platform narrative. Tenable’s cloud security platform achieved FedRAMP High and Impact Level 5 authorization, improving its ability to support U.S. federal agencies. The company also announced AI-powered cloud detection and response capabilities and more than 300 pre-built integrations through the Tenable One Open Connector.

CrowdStrike, Palo Alto Networks and Wiz highlight the pressure from larger and cloud-focused security platforms. Their presence makes TENB’s push into cloud, identity and operational technology more necessary as customers consolidate security spending.

TENB Must Keep Its AI Edge From NarrowingThe same AI trend expanding demand also raises competitive risk. If AI lowers the cost and complexity of building vulnerability discovery and prioritization tools, adjacent vendors could move deeper into exposure management.

That risk is not abstract. Qualys, Rapid7, CrowdStrike, Palo Alto Networks and Wiz are all capable of narrowing TENB's AI edge if they close the gap on automation and prioritization.

Partnerships with OpenAI and Anthropic help TENB stay close to frontier model development. Tenable has participated in OpenAI’s Trusted Access for Cyber program and has worked with Anthropic to integrate Claude-powered workflows into Hexa AI.

Those relationships are useful, but they are not enough on their own. Because they are non-exclusive, TENB still has to convert early access into durable product advantages that are hard for peers to replicate.

Tenable’s Ratings Reflect Trend Strength, Stock RiskThe bottom line is that TENB is tied to a powerful cybersecurity trend, but the stock still carries execution risk. AI-driven vulnerability discovery may continue to lift demand for exposure management, yet TENB must prove that platform breadth, automation and partner access can translate into sustained growth.

The Zacks Consensus Estimate for TENB’s 2026 earnings is pegged at $1.95 per share, unchanged over the past 30 days and indicating 22.64% year-over-year growth.

TENB currently carries a Zacks Rank #4 (Sell). That rank points to a weak short-term earnings estimate revision setup, even though the company has favorable Style Scores.

You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

The stock has a Growth Score of A, Momentum Score of A and VGM Score of A. These scores suggest favorable growth and momentum characteristics, but Style Scores are best used with the Zacks Rank. For now, the trend is promising, while the stock still needs clearer proof of sustained execution and improved estimate momentum.

COLUMBIA, Md., July 01, 2026 (GLOBE NEWSWIRE) -- Tenable® Holdings, Inc. (NASDAQ: TENB), the exposure management company, today announced that Gartner has identified Tenable as the company to beat for AI-powered exposure assessment in its report, AI Vendor Race: Tenable Is the Company to Beat for AI-Powered Exposure Assessment.

According to Gartner, "Tenable's long-standing dominance in vulnerability assessment, its strong asset and attack surface discovery capabilities, and its ability to execute on its AI strategy make it the front-runner in AI-powered exposure assessment."

The Gartner report further notes that, “Tenable’s broad attack surface coverage sets it apart from competitors. Tenable One is a well-integrated platform that spans traditional IT, identity, cloud, CPS and container environments.” Gartner adds that, “This visibility extends to emerging attack surfaces such as AI. Tenable identifies shadow AI usage and can also prioritize AI exposures like sensitive data leakage, misconfigurations, novel AI attacks, risky agent behavior, and unsafe integrations with external tools.”

“Cybersecurity is entering a new era where AI is changing both how organizations operate and how attackers exploit them," said Mark Thurmond, co-CEO, Tenable. "Organizations need a modern approach that not only gives them complete visibility across their expanding attack surface, but helps them act on risk faster. We believe Gartner's recognition reflects our continued commitment to enabling customers to keep pace with that change.”

We feel the Gartner recognition builds on a series of recent AI milestones for Tenable. In recent months, the company announced the general availability of Tenable Hexa AI, the agentic AI engine inside the Tenable One Exposure Management Platform, expanded its Tenable One AI Exposure capabilities to help customers protect their AI attack surface, and joined a select group of cybersecurity companies participating in both Anthropic's Project Glasswing initiative and OpenAI's Daybreak Cyber Partner Program. Together, these investments are helping shape the next generation of AI-powered cybersecurity while enabling customers to move beyond identifying exposures to continuously prioritizing and reducing cyber risk.

“We're still in the early innings of AI in cybersecurity,” said Steve Vintz, co-CEO, Tenable. “The next phase isn't just identifying exposures – it's enabling security teams to continuously understand, prioritize and remediate them with AI working alongside people. That's where we're investing, and where we believe the market is headed.”
