Israel Industry & Tech Cybersecurity Startups

Top Cybersecurity Startups in Israel (2026): The 12 to Know

Updated October 2026 · 12 picks

The top cybersecurity startups in Israel in 2026 are Cyera (data security, valued above $12 billion), Cato Networks (SASE), Island (the enterprise browser), Upwind (cloud security) and Claroty (industrial security). All five are still independent after a year in which Wiz, CyberArk and Armis were bought. Twelve, below.

Israel builds more cybersecurity companies per head than anywhere in the world, and 2026 has been a record year at both ends: Google closed its $32 billion purchase of Wiz in March, Palo Alto Networks completed its CyberArk deal and ServiceNow bought Armis, while the next generation raised some of the largest private rounds in the industry. This list covers the companies that are still independent, still private and still growing, ordered by scale and momentum as of October 2026.

1. Cyera

The most valuable private Israeli security company, and the one consolidating the market.

Focus Data security (DSPM) and AI data protectionFounded 2021HQ New York and Tel AvivStatus Private, valued above $12B (2026)

Cyera maps where an organization's sensitive data lives across cloud and SaaS, who can reach it and how exposed it is, then fixes the risky access. That category, data security posture management, has become central as companies feed their data to AI.

It raised three times in 2026, ending above a $12 billion valuation, and used that capital to buy Israeli startups including Oasis Security, Ryft and Genie Security. It is the clearest candidate to become the next Wiz-sized outcome.

2. Cato Networks

Israel's long-running SASE leader, founded by Check Point co-founder Shlomo Kramer.

Focus SASE: networking and security from the cloudFounded 2015HQ Tel AvivStatus Private, valued at $4.8B

Cato replaces the branch-office tangle of firewalls, VPNs and network boxes with a single cloud service that routes and secures all traffic. It was one of the first to build this architecture from scratch rather than bolt it onto hardware.

It is among Israel's largest private software companies by revenue and has been widely tipped for an IPO. For a reader trying to understand the Israeli cyber establishment, Cato is the bridge between the Check Point generation and the Wiz generation.

3. Island

Turned the web browser into the corporate security perimeter, and raised $400 million to keep going.

Focus Enterprise browser securityFounded 2020HQ Dallas and Tel AvivStatus Private, valued at $6.4B (2026)

Island builds a Chromium-based browser for companies that controls copy, paste, download and data sharing at the point where employees actually work. It replaces a stack of virtual desktops and remote-access tools.

In September 2026 it raised $400 million at a $6.4 billion valuation, one of the largest security rounds of the year anywhere. Its success has spawned a whole category of Israeli browser-security startups.

4. Upwind

The fastest-rising cloud security company of 2026, with three rounds in nine months.

Focus Cloud security (CNAPP) built on runtime dataFounded 2022HQ San Francisco and Tel AvivStatus Private, valued at $3.8B (2026)

Upwind secures cloud workloads by watching what actually runs in production rather than only scanning configurations, which cuts the noise that buries security teams.

Its valuation climbed from $1.5 billion in January 2026 to $3.8 billion after a $300 million round in September, and it bought AI security startup Aegis. With Wiz now inside Google, Upwind is the independent Israeli name in cloud security.

5. Claroty

The leader in protecting factories, hospitals and critical infrastructure.

Focus Cyber-physical and industrial (OT) securityFounded 2015HQ New York and Tel AvivStatus Private, valued at $3B (2026)

Claroty secures the machines that run the physical world: industrial control systems, building management and connected medical devices, via its Medigate acquisition. Those environments cannot be patched like laptops, which is what makes the problem hard.

Incubated by Team8, it raised $150 million at a $3 billion valuation in January 2026 and is among the most likely Israeli cyber companies to go public.

6. Snyk

Put security tools in developers' hands, and built one of the most-used AppSec platforms.

Focus Developer and application securityFounded 2015HQ Boston, London and Tel AvivStatus Private

Snyk scans code, open-source dependencies, containers and infrastructure-as-code for vulnerabilities inside the tools developers already use, rather than at the end of the release process.

Founded by Guy Podjarny and a Tel Aviv and London team, it passed roughly $300 million in annual revenue in 2024. It now competes in AI code security, a crowded 2026 category.

7. Torq

Uses AI agents to do the repetitive work of a security operations center.

Focus AI security operations (autonomous SOC)Founded 2020HQ Tel Aviv and the USStatus Private, valued at $1.2B (2026)

Torq automates triage, investigation and response across a company's security tools, so analysts handle decisions rather than tickets. It has positioned itself as the AI SOC platform for large enterprises.

It raised $140 million at a $1.2 billion valuation in January 2026 and bought Israeli application security startup Jit in May.

8. Silverfort

Protects the identities attackers use to move through a network, including service accounts.

Focus Identity security and threat protectionFounded 2016HQ Tel Aviv and BostonStatus Private

Silverfort enforces multi-factor authentication and access policies on systems that were never built to support them, such as legacy servers, command-line tools and machine accounts.

Identity is where most breaches now start, and Silverfort has become one of the reference vendors in identity threat detection. It bought Israeli startup Fabrix in 2026.

9. Noma Security

One of the best-funded companies in Israel's hottest new category.

Focus Security for AI applications and agentsFounded 2023HQ Tel Aviv and New YorkStatus Private

Noma gives security teams an inventory of every AI model, agent and data pipeline in the organization, then tests and monitors them for leaks, misuse and prompt manipulation.

Founded in 2023, it has raised over $130 million and was named in CTech's 50 most promising Israeli startups of 2026.

Website

10. Zenity

Secures the AI agents and low-code apps that business teams build themselves.

Focus AI agent security and governanceFounded 2021HQ Tel Aviv and the USStatus Private

Zenity started by securing low-code and no-code tools like Microsoft Copilot Studio and Power Platform, which put it in the right place when enterprises began building AI agents on the same platforms.

It raised a $125 million Series C in 2026, taking total funding to around $185 million.

11. Vega

Lets security teams investigate threats where the data already sits, in plain language.

Focus Security analytics and threat investigationFounded 2024HQ Tel Aviv and New YorkStatus Private, valued at $800M (2026)

Vega runs detection and investigation directly on an organization's existing data stores instead of forcing everything into an expensive SIEM first, and lets analysts query it in natural language.

Founded in 2024, it raised a $120 million Series B led by Accel in February 2026 at an $800 million valuation, one of the fastest climbs in the sector.

Website

12. Guardio

Israel's consumer cyber unicorn, protecting people rather than companies from phishing and scams.

Focus Consumer cybersecurityFounded 2018HQ Tel AvivStatus Private, valued at $1.1B (2026)

Guardio's browser extension and app block phishing sites, scam messages and malicious downloads for individual users, a market most Israeli security companies ignore.

It raised $40 million at a $1.1 billion valuation in September 2026, with Wiz co-founder Assaf Rappaport joining. Its whole team is in Israel.

Frequently asked questions

What is the biggest cybersecurity startup in Israel?

Cyera is the most valuable independent Israeli cybersecurity startup in 2026. It raised $400 million in January, $600 million in June and a further extension in September, taking its valuation above $12 billion, and it has been buying smaller Israeli security companies along the way. Before its sale to Google, Wiz held that title.

Why is Israel so strong in cybersecurity?

Three things compound. The IDF's intelligence units, above all Unit 8200, train thousands of young engineers in offensive and defensive security every year. A dense network of cyber-specialist investors (Cyberstarts, Team8, YL Ventures, Glilot) funds them early. And each big exit, from Check Point to Wiz, sends experienced founders and early employees back into new companies.

What were the biggest Israeli cybersecurity exits?

Google's $32 billion acquisition of Wiz, completed in March 2026, is the largest Israeli exit ever. Palo Alto Networks' purchase of CyberArk for around $25 billion, ServiceNow's $7.75 billion deal for Armis and Proofpoint's agreed $6.3 billion acquisition of Varonis (October 2026) follow it. Dozens of smaller security startups were bought in 2026 alone.

Where are Israel's cybersecurity companies based?

Mostly in Tel Aviv and the Herzliya to Ramat Gan corridor, with a growing cluster at the CyberSpark park in Beer Sheva next to Ben-Gurion University and the IDF's technology campus. Most of the companies on this list keep R&D in Israel and a sales headquarters in New York, Boston or San Francisco.

Which Israeli cyber startups are hiring?

The fastest-growing ones on this list (Cyera, Upwind, Island, Torq and the AI security companies Noma and Zenity) have been adding staff through 2026 on the back of large rounds. Check each company's careers page directly, and see our separate guide to the best tech companies to work for in Israel.

What is AI security and why are so many Israeli startups doing it?

AI security protects the models, agents and data pipelines companies now run: who an AI agent can act as, what data it can reach and whether it can be manipulated. It is the hottest category in Israeli cyber in 2026, with Noma, Zenity, Onyx and others raising large rounds, because every enterprise rolling out AI agents needs controls that did not exist two years ago.
