In a potential blockbuster exit that underscores the frothy valuations in Israeli cybersecurity M&A 2025, Armis—the pioneering agentless cybersecurity platform—is reportedly in advanced negotiations for a $7 billion sale, according to sources cited by Calcalist and corroborated by Bloomberg. The deal, if finalized, would mark one of the largest acquisitions in the cybersecurity sector this year, rivaling recent mega-deals like Thoma Bravo’s $8.5 billion buyout of Darktrace earlier in 2025.

Armis at a Glance: From Startup to Unicorn Leader
Founded in 2015 in Palo Alto with deep Israeli R&D roots, Armis has disrupted the cybersecurity landscape with its agentless approach to asset visibility and security. Unlike traditional endpoint detection tools requiring software installation, Armis uses passive monitoring of network traffic, Wi-Fi signals, and device behaviors to discover and protect the exploding Internet of Things (IoT) ecosystem—projected to reach 30 billion connected devices by 2030, per McKinsey’s latest IoT report.
The company’s platform secures everything from medical devices in hospitals to OT systems in manufacturing plants, addressing a critical gap amid rising ransomware attacks on unmanaged assets. Armis has raised over $500 million from blue-chip investors including Sequoia Capital, Andreessen Horowitz, and Lightspeed Venture Partners, achieving unicorn status at a $3.4 billion valuation in its 2021 Series D. Revenue has reportedly surged to $200 million+ ARR as of mid-2025, driven by enterprise wins at Fortune 500 clients like Pfizer, AWS, and Airbus.
Deal Dynamics: Strategic Buyers and Private Equity in the Mix
Reports indicate interest from a consortium of strategic acquirers—potentially including Palo Alto Networks, Cisco, or Microsoft—alongside private equity giants like Thoma Bravo and Symphony Technology Group, known for aggressive roll-ups in cybersecurity. The $7 billion enterprise value implies a 35x revenue multiple, premium to the sector’s 2025 median of 22x for high-growth cyber firms, per Bain & Company’s Q4 M&A report.
Strategic rationale centers on agentless cybersecurity synergies: Buyers seek Armis’s tech to bolster zero-trust architectures amid regulatory pressures like the U.S. CISA’s IoT security mandates. For PE firms, it’s a classic bolt-on play—Armis could anchor a platform acquiring adjacent players in OT security or AI-driven threat detection, echoing KKR’s playbook with firms like Optiv.
| Company | Buyer | EV ($B) | Revenue Multiple | Date |
|---|---|---|---|---|
| Armis (Reported) | TBD | 7.0 | 35x | Q4 2025 |
| Darktrace | Thoma Bravo | 8.5 | 28x | Q2 2025 |
| KnowBe4 | Vista Equity | 4.6 | 20x | Q1 2025 |
| Wiz | Google (Failed) | 23.0 | 50x+ | 2024 |
Israeli Tech Ecosystem Implications: M&A Resurgence Amid Geopolitical Headwinds
This deal arrives as cross-border M&A trends 2025 favor Israeli cyber exits, with $15 billion in transactions YTD per IVC Research Center data—up 40% YoY despite regional tensions. Armis’s sale would follow Check Point’s $1.2 billion acquisition of Perimeter 81 and CyberArk’s PE-backed growth, highlighting Israel’s dominance in cyber (home to 20% of global unicorns in the sector, per Startup Nation Central).
However, risks loom: U.S. antitrust scrutiny under the Biden-Harris FTC has stalled deals like Wiz-Google, and CFIUS reviews could complicate foreign buyer involvement given Armis’s dual-use tech. Kirkland & Ellis partners note in recent filings that private equity exit strategies in cybersecurity now prioritize U.S.-based acquirers to mitigate regulatory drag.
Broader Market Signals: Cyber Valuations at Inflection?
Goldman Sachs’ 2025 Tech M&A Outlook flags cybersecurity as the hottest subsector, with deal volume up 25% amid AI-driven threats. Yet, BCG warns of a valuation reset: Multiples could compress to 18x by 2026 as interest rates stabilize and LPs demand disciplined PE returns. For C-level execs eyeing similar exits, Armis exemplifies timing the window—leverage ARR growth above 50% YoY and defensible IP moats.
Leadership at Armis, led by CEO Ron Gula (ex-Tenable CTO), positions the firm for seamless integration, with no immediate layoffs signaled in reports. If inked, this $7 billion transaction could catalyze a wave of Israeli cybersecurity acquisitions 2025, reinforcing Tel Aviv’s status as the world’s cyber capital.
- Key Takeaway for Investors: Agentless platforms command premiums in IoT/OT security; monitor for follow-on deals in adjacent spaces like SASE.
- Risk Factor: Geopolitical volatility may accelerate U.S. strategic buys over PE take-privates.
