Is Skybox Security still in business in 2026?

No. Skybox Security ceased all operations on February 24, 2025, laid off its entire roughly 300-person workforce, and filed for insolvency in Israel. Select IP, trademarks, and customer data were sold to rival Tufin in an asset sale, not a company acquisition. The company has zero revenue and zero employees as of 2026.

Who acquired Skybox Security?

Tufin acquired select IP, trademarks, and customer information from Skybox in an asset sale on February 24, 2025. This was not an acquisition of the company itself; Tufin took no contracts or support obligations, and Skybox's domain now redirects to tufin.com.

Could AI replace Skybox Security's products?

The question is moot since Skybox no longer operates, but its rules-based firewall analysis and vulnerability correlation workflows are now automated by successor Tufin's AI product, TufinAI, which won RSAC 2025 Best of Show and drove Tufin's record 2025 results reported February 5, 2026.

Who is Skybox Security's biggest competitor?

Tufin, which acquired Skybox's assets in February 2025 and now markets itself as capturing stranded Skybox customers, along with AlgoSec and FireMon; FireMon actively promoted landing Skybox customers in an April 23, 2025 blog post.

How much funding did Skybox Security raise before shutting down?

Skybox raised roughly $335 million in lifetime funding, including a $150M round in 2017 led by CVC Capital Partners' Growth Fund with Pantheon Ventures, and a final $50M round in February 2023 from CVC, Pantheon, and J.P. Morgan.

Why did Skybox Security fail?

Insiders told reporters Skybox's SaaS transition failed to gain traction, leaving the company dependent on a shrinking existing customer base rather than new business between 2023 and 2025. It ultimately filed for insolvency in Israel with about $26M in secured debt to J.P. Morgan, shutting down February 24, 2025.

The call

Skybox Security shut down completely in February 2025 and its remains were absorbed by Tufin; the company itself no longer operates.

Skybox Security made software to help companies check if their security settings were correct and followed the rules. The company could not compete with bigger rivals like Tufin and CrowdStrike, which offered similar tools as part of larger security packages, and AI automation made Skybox's work easier for others to copy. The company ran out of money, laid off all 300 employees, filed for bankruptcy in February 2025, and sold its customers and technology to competitor Tufin; as of mid-2026, it has no operations, no staff, and no business value whatsoever.

Why

AI pressure: TufinAI (Tufin's AI-driven posture automation). Skybox no longer exists to be eaten; AI already runs the same rules-based correlation work through the buyer of its IP. Could AI do the core job? Yes, likely.

Bigger players: Tufin, CrowdStrike, SentinelOne, Microsoft. Tufin bought Skybox's IP, trademarks, and customer data in an asset sale after Skybox's total collapse in Feb 2025. Could a giant copy it? Yes, easily.

What protects it. None; the company has zero staff, zero revenue, and no assets left after full liquidation.

What would change this call

Tufin publishes customer migration counts or renewal figures from former Skybox accounts. Would confirm scale of customer transfer from Skybox to Tufin.
Israeli insolvency proceeding resolves creditor claims (J.P. Morgan, suppliers, landlords). Would show whether any residual assets or brand rights get sold again.
AlgoSec or FireMon announce dedicated 'Skybox migration' programs or win specific named former Skybox customers. Would show customer base splitting beyond just Tufin.
