IPOs Make a Comeback: 9 Cybersecurity Startups to Watch in 2025

IPOs Make a Comeback: 9 Cybersecurity Startups to Watch in 2025

After years of silence, the initial public offering market is thawing, and cybersecurity startups are emerging from the wings. The 2025 IPO recovery—marked by 347 completed listings raising $33.6 billion, a 20% surge in deal volume from the prior year—has restored investor appetite for growth stories in enterprise technology.

Within this thaw lies particular opportunity for a cohort of well-capitalized, late-stage security firms that have spent the past several years building resilient businesses while waiting for market conditions to align.

This moment has arrived. Successful debuts by enterprise security companies in 2025 have signaled that the market can accommodate quality cybersecurity IPOs. Netskope, the cloud security vendor, priced its offering at $19 per share in September, the top of its revised range, and surged 18% on its first day of trading, ultimately reaching an $8.6 billion valuation.

SailPoint, the identity governance company, also achieved a strong public reception in February. These outcomes have prompted executives of other late-stage security firms to reassess their previously shelved IPO timelines, and several have now begun actively preparing for listings in 2026 or 2027.

Renaissance Capital forecasts that between 200 and 230 companies will pursue public offerings in 2026, with potential proceeds reaching $60 billion—a meaningful recovery that reflects renewed confidence in public markets and improving valuations across growth-stage software. For cybersecurity specifically, the tailwinds are structural.

Ransomware attacks surged 126% in the first quarter of 2025 compared to the same period in 2024, corporate spending on security technology continues to accelerate, and venture capital remains concentrated in defense-focused platforms—particularly those leveraging artificial intelligence for threat detection and response.

Nine private cybersecurity firms now stand at the forefront of this IPO pipeline.

Each has raised substantial capital from blue-chip investors, achieved meaningful revenue scale, and signaled either explicit or implicit readiness for public markets. The following companies represent the most credible near-term candidates.

Snyk: Developer Security at $7.4 Billion

Snyk has long occupied a position of inevitability on IPO watch lists. The Israeli application security startup, which provides developers with tools to identify and remediate vulnerabilities in open source libraries, containers, code, and infrastructure-as-code, reached a valuation of $7.4 billion in its most recent funding round in December 2024, a $196.5 million raise.

More significantly, the company announced in December 2024 that it had achieved $300 million in annual recurring revenue (ARR)—a threshold that historically indicates readiness for public markets in the SaaS segment.

CEO Peter McKay, in comments to TechCrunch, confirmed that an IPO is planned for 2026, though not imminently. "We've got $435 million in the bank and are very close to break-even. In 2025, we won't burn any cash, so I can pick the time when I go public. I don't need to rush," McKay said.

The company was previously known to have drafted a confidential prospectus with the SEC in January 2024, with initial plans to file within months—plans that were deferred as market conditions remained uncertain. McKay has expressed confidence that 2026 will provide an even more favorable regulatory and economic environment than 2025, and Snyk's pathway to sustained positive operating cash flow positions it to meet institutional investor expectations by mid-2026.

Snyk's strategic focus on AI-assisted vulnerability detection and its position as the market standard for developer-first security have resonated with both enterprise and venture investors.

The company has weathered the SaaS slowdown of 2022-2023 through workforce restructuring and disciplined capital allocation, and it now occupies a position of considerable strength from which to mount an IPO.

Armis: Cyber Exposure Management at $6.1 Billion, Pre-IPO Ready

In November 2025, Armis, a nine-year-old Israeli cybersecurity firm, announced a $435 million pre-IPO funding round at a $6.1 billion valuation—a decisive signal of management's commitment to the public markets.

The round, led by Growth Equity at Goldman Sachs Alternatives with significant participation from Google Ventures and Evolution Equity Partners, represents a repricing upward from an August 2025 tender offer valuation of $4.5 billion. More tellingly, CEO Yevgeny Dibrov explicitly declared an IPO target of late 2026 or early 2027, and characterized the pathway to public markets as a "personal dream" worthy of capital investment to accelerate.

Armis provides cyber exposure management and security software for managing and protecting devices across operational technology, information technology, medical devices, cloud infrastructure, and code environments.

The company currently serves over 40% of the Fortune 100, including major customers in financial services, healthcare, manufacturing, and government. Armis disclosed that it has achieved $300 million in ARR and intends to reach $500 million in ARR and cash-flow positivity before its IPO.

The pre-IPO round also signals conviction from tier-one venture and strategic investors. Google's CapitalG committed meaningful capital—a signal that Alphabet views Armis as aligned with its cloud and cybersecurity strategy, despite the company not being a strategic acquisition target.

This mix of investor participation, coupled with deliberate capital allocation toward product and commercial expansion, positions Armis as one of the strongest near-term IPO candidates.

ID.me: Digital Identity at $2 Billion, Government Scale

ID.me, a digital identity verification platform trusted by the U.S. federal government, state agencies, healthcare organizations, and over 600 consumer brands, has experienced blockbuster capital inflows in 2025.

The company announced a $275 million credit facility from Ares Management in January 2025, followed by a $340 million Series E funding round in September 2025 led by Ribbit Capital at a valuation exceeding $2 billion. The nine-month period of capital deployment reflects exceptional demand for identity verification solutions in a landscape increasingly threatened by AI-driven fraud.

ID.me serves a dual market. On the public sector side, the company is the trusted digital identity provider for 19 federal agencies, 44 state governments, and 66 healthcare systems. During the pandemic, states attributed over $270 billion in prevented unemployment insurance fraud to ID.me's platform.

On the commercial side, over 600 brands use ID.me to verify customer identities and communities, providing a foundation for secure, reusable digital wallets that enable seamless authentication across organizations.

CEO Blake Hall has positioned ID.me at the intersection of AI adoption and fraud mitigation. As AI agents proliferate and organizations require trusted identity tokens for secure machine-to-machine and human-to-machine interactions, ID.me's technology becomes increasingly foundational.

The company's rapid 2025 capital raises, coupled with demonstrated traction across both government and commercial segments, suggest that management views 2026 as a plausible IPO window. While the company has not made explicit IPO announcements, the scale and pace of fundraising—combined with the market validation provided by tier-one venture capital participation—positions ID.me as a likely candidate if market conditions remain supportive.

Island: Enterprise Browser at $4.8 Billion

Island, an enterprise browser company founded in 2020 by Mike Fey (former CEO of Symantec) and Israeli entrepreneur Dan Amiga, represents a newer category entrant in cybersecurity. The company has achieved remarkable valuation appreciation: $1.5 billion in 2023, $3 billion in April 2024, and $4.8 billion in March 2025 following a $250 million Series E funding round led by Coatue Management.

This 60% year-over-year valuation appreciation reflects market confidence in the strategic opportunity of transforming the browser into a security-enforced gateway for enterprise applications.

Island's platform replaces traditional enterprise browsers with a secure, high-performance alternative built on open-source Chromium.

The browser collects security telemetry, enforces access controls, prevents data exfiltration, and provides IT teams with comprehensive visibility into employee activity and application behavior. The company now serves seven of the largest ten U.S. banks and counts a growing roster of Fortune 100 customers.

The company maintains over $530 million in liquid assets and continues to expand its engineering organization. Coatue Management's repeated investment in Island across funding rounds signals confidence that the enterprise browser category will continue to mature and that Island's total addressable market remains substantial.

While Island's CEO Mike Fey has historically suggested that an IPO is a future ambition "someday" rather than an imminent event, the capital raise in March 2025 and the company's accelerating customer penetration suggest that a 2026 or 2027 IPO remains within the realm of possibility if market conditions warrant.

Cohesity: AI Data Security Backed by Nvidia

Cohesity, a Nvidia-backed data security and resilience platform, represents a strategic addition to the IPO pipeline. In September 2025, CEO Sanjay Poonen confirmed that the company is actively preparing for a 2026 IPO after abandoning a planned acquisition of Veritas, the data management software company.

Cohesity's AI-powered data protection platform addresses critical customer needs around securing, protecting, and recovering from modern ransomware and data loss scenarios.

The company serves Fortune 500 organizations across industries, including customers such as FedEx and Comcast. Cohesity's dual-product strategy—combining data protection with data governance and analytics capabilities—positions the company to benefit from increasing regulatory scrutiny around data residency, privacy, and compliance.

Nvidia's strategic backing provides both credibility and commercial momentum, particularly as enterprise customers increasingly prioritize AI-safe data environments.

Illumio: Zero-Trust Microsegmentation at $2.75 Billion

Illumio, a pioneer in zero-trust segmentation architecture, has long been identified as a potential IPO candidate.

The company, which provides microsegmentation platforms to prevent lateral movement of adversaries within enterprise networks, last raised capital in June 2021 at a valuation of $2.75 billion in a Series F round led by Thoma Bravo and Franklin Templeton. The funding round generated more than $225 million and brought total capital raised to over $550 million.

Despite the passage of several years without additional institutional fundraising, Illumio has continued to demonstrate strong revenue growth and customer adoption. CEO Andrew Rubin has stated that the company is in no particular rush to pursue an IPO, reflecting a posture of optionality rather than urgency.

However, Thoma Bravo's track record of taking cybersecurity companies public—and its history of holding portfolio companies for defined periods before orchestrating exits—suggests that an IPO remains a plausible outcome within the 2026-2027 timeframe if market conditions support it.

Arctic Wolf: Security Operations at $4.3 Billion

Arctic Wolf, a managed detection and response (MDR) provider serving primarily mid-market and large-enterprise customers, has been a fixture on IPO watch lists since at least 2021.

In a Series F funding round, the company raised $150 million at a valuation of $4.3 billion. CEO Nick Schneider, who elevated to the role shortly before the Series F round close, stated at the time that an IPO was "probably a year out, give or take a quarter."

Arctic Wolf's cloud-native security operations platform processes over 65 billion security events daily and delivers threat detection, investigation, and response services through a combination of automated machine learning and human security expertise.

The company has grown large-enterprise revenue 438% year-over-year and has maintained 100% year-over-year revenue growth for seven consecutive years. With approximately 3,000 customers and recent expansion into Europe, the Middle East, Africa, and plans for Asia-Pacific and Latin America, Arctic Wolf represents a geographically diversifying security operations platform.

In November 2025, CEO Schneider indicated to Axios that the company remains "on the hunt" for strategic acquisitions while preparing for an eventual IPO. The company's posture toward public markets has evolved from caution to active preparation, though no explicit IPO timeline has been announced.

Strong relative metrics when benchmarked against public peers like CrowdStrike—and an enhanced commercial footprint following geographic expansion—position Arctic Wolf as a credible 2026-2027 IPO candidate.

Immuta: Cloud Data Access Control

Immuta, headquartered in Boston and founded in 2015, is the market leader in cloud-native data access control.

The company provides data engineering and analytics teams a single platform to automatically discover, classify, secure, and monitor sensitive data across cloud data warehouses and lakehouse platforms, including Snowflake, Databricks, AWS Redshift, Azure Synapse, and Google BigQuery.

In June 2022, Immuta raised a $100 million Series E funding round that valued the company at $1 billion, bringing total capital raised to $267 million.

The funding round included participation from NightDragon, led by Dave DeWalt (former CEO of FireEye, McAfee, and Documentum), as well as from existing investors Ten Eleven Ventures and Intel Capital.

While Immuta has not made explicit IPO announcements, the company's market leadership position in a critical data governance category, combined with the accelerating adoption of AI agents and large language models requiring controlled data access, suggests that data access control will become an increasingly important category for public market investors.

The company's backing by prominent venture capital and strategic partners positions it as a potential 2026-2027 IPO candidate, particularly if market conditions support infrastructure and platform software listings.

OneTrust: Data Privacy and Compliance at $4.5 Billion

OneTrust, a privacy compliance and data governance platform founded in 2016, has evolved from a single-point solution (cookie consent management via its acquisition of Optanon from the U.K.-based Silktide) to a comprehensive platform spanning privacy operations, third-party risk management, AI governance, and GRC workflows.

The company now serves over 14,000 customers, including 75% of the Fortune 100, and generates approximately $550 million in annual recurring revenue.

In November 2025, OneTrust disclosed that it is exploring strategic options, including a private equity sale or public offering. The privacy compliance market has matured considerably since the initial wave of GDPR adoption in 2018-2019, and growth has moderated from the explosive 100%+ ARR growth rates of the early years.

However, the emergence of AI governance as a distinct regulatory and risk management category—accelerated by recent guidance from the SEC, FTC, and international regulators—has re-energized the market opportunity.

CEO Kabir Barday has stated previously that the company was "prepared to be private and profitable for a long time," suggesting a lower urgency toward public markets compared to other cohort members. However, recent disclosure of strategic review processes indicates that management and investors are actively considering options.

If OneTrust pursues an IPO, the company's dual market positioning—serving both traditional privacy compliance needs and the emerging AI governance category—could prove compelling to public market investors evaluating digital trust infrastructure.

Market Context: Conditions Supporting the Pipeline

The nine companies above operate within a favorable macroeconomic environment for software IPOs. Interest rate expectations have moderated from the peaks of 2022-2023, helping multiples on growth-stage software to normalize and making earlier-stage companies' private valuations appear more defensible relative to public markets.

Venture capital has demonstrated particular concentration in late-stage funding rounds, with investors increasingly favoring proven, capital-efficient models over early-stage exploration.

The cybersecurity market specifically has benefited from accelerating adoption of AI-driven threat detection and defense mechanisms. Venture capital invested $9.5 billion into cybersecurity startups in 2024 across 304 funding rounds, with Q1 2025 delivering $2.2 billion across just 85 deals—reflecting a shift toward larger, fewer deals at mature companies.

This concentration has elevated the median maturity and scale of private cybersecurity companies relative to historical cohorts, supporting the thesis that a substantial IPO pipeline now exists.

Additionally, recent successful cybersecurity IPOs have reestablished valuation benchmarks and institutional appetite. Netskope's September 2025 offering and SailPoint's February 2025 listing demonstrated that public markets can reward profitable or near-profitable growth-stage security companies with reasonable revenue multiples.

These precedents matter: they provide proof of concept for CFOs and boards of later-stage startups, reducing perceived execution risk around IPO readiness and marketing narratives.

Timing and Risks

Renaissance Capital and investment banking advisory firms project that IPO volumes will accelerate in the first half of 2026, before potential mid-year volatility related to the U.S. presidential election cycle.

Several of the nine companies above have explicitly targeted late 2026 or early 2027 for IPO launches, suggesting confidence that market windows will remain open through the first half of the year.

However, material risks remain. Sustained volatility in equities, resurgence of inflation, or contraction in enterprise technology spending could force repricings and timeline delays, as occurred in 2022-2023.

Additionally, regulatory scrutiny of cybersecurity and data privacy practices—particularly if future administrations prioritize different policy priorities—could create execution risk for companies whose market narratives depend on specific regulatory tailwinds.

The cohort of nine also faces embedded competitive dynamics. Market consolidation, acquisition interest from larger software companies and private equity sponsors, and the possibility of breakthrough innovation by emerging entrants could reshape IPO timing and valuations.

Immuta, OneTrust, and Illumio, for instance, have each reportedly received acquisition interest and strategic overtures in recent years, raising questions about whether an IPO or a controlled exit to a financial or strategic buyer represents the optimal path.

Nevertheless, the convergence of capital availability, demonstrated market readiness at scale, successful recent precedents, and structural tailwinds in cybersecurity adoption suggest that 2026 will see at least several of these nine firms move forward with public offerings.

The IPO market for enterprise software, long dormant, is no longer a question of whether, but rather of timing and execution.
