White Cloud Security

What White Cloud Security does

White Cloud Security, Inc. is a privately-held cybersecurity company founded in 2014 and headquartered in Austin, Texas, that builds the Trust Lockdown Suite, a zero-trust endpoint application control platform. The product implements a Default-Deny security model that blocks all unauthorized software from executing on Windows and Linux endpoints, using a proprietary 6-Factor file identification technology (SHA-1, SHA-256, SHA-512, MD5, CRC32, and file length) to authenticate software at the kernel level. Trust Lockdown is delivered as both a cloud-hosted SaaS (available on AWS Marketplace with 21 cloud zones) and an on-premises Data Center Appliance (DCA), with complementary TAME Team managed services and TAME Training offerings. The company has expanded into adjacent security categories under a broader brand portfolio that includes JEWELS SAFE GRC, JEWELS SAFE Vault, DARK Agent, KnowMail, SafeClick, and LIGHT RAYS trademarks.

The company sells through three motions: enterprise field sales (Schedule a Demo), AWS Marketplace self-service listing, and a small channel partner network led by Altair-775 in Ukraine, Cobussa, and Network Box USA. Customers are concentrated in compliance-heavy verticals — government, healthcare, military/defense, financial services, gaming, insurance, emergency/911, air traffic control, and medical devices — where the company actively markets alignment with ACSC, CMMC Level 1, and NIST 800-171, and holds a formal G-2 certification from Ukraine's SSSCIP (October 25, 2024). Pricing is quote-based, annual, and not publicly disclosed, and the company operates on a subscription (SaaS/DCA) plus managed services plus professional services revenue model.

White Cloud Security has no disclosed institutional funding, is privately held, and operates with 11-50 employees. The company has built its positioning around the August-2024 CrowdStrike BSOD and the 2024 Ascension Health ransomware incident (5.6 million affected patients) as evidence that signature-based detection and frequent-update endpoint agents are structurally fragile, and that default-deny prevention is the more defensible architectural choice. Ongoing thought-leadership content, a February 2025 DCA software update (1.5.1), and continued trademark expansion indicate continued commercial and product investment despite limited disclosed growth metrics.

Core offering

White Cloud Security sells the Trust Lockdown Suite, a zero-trust application control platform that prevents unauthorized software, malware, and untrusted code from executing on endpoints through default-deny enforcement. The product uses a patented 6-factor file identification method combining SHA-1, SHA-256, SHA-512, MD5, CRC32, and file length hashes to evaluate executables, and is delivered as cloud-hosted SaaS, an on-premises Data Center Appliance (DCA), with dedicated Windows and Linux Security Agents. The offering is complemented by TAME Team managed services and TAME Training services.

Product overview

White Cloud Security offers the Trust Lockdown Suite, a unified zero-trust security platform centered on Default-Deny execution control. The core product is Trust Lockdown, available in two deployment models: the cloud-hosted Trust Lockdown (SaaS) for organizations preferring managed cloud infrastructure, and Trust Lockdown (DCA) for on-premises data center deployment. These are supported by TAME Team (managed security operations) and TAME Training (customer education). The platform employs 6-factor file identification technology combining SHA-1, SHA-256, SHA-512, MD5, CRC32, and file length to uniquely authenticate and authorize software before execution. Windows and Linux Security Agents enforce policies at the kernel level, blocking all unauthorized executables without requiring threat signatures or continuous software updates.

Broad incumbents

• CrowdStrike: CrowdStrike is the dominant cloud-native endpoint security platform (Falcon) offering EDR, XDR, and increasingly zero-trust capabilities. Listed as a direct comparison on White Cloud Security's site; competes in the same buyer conversations, but as part of a much broader portfolio rather than a specialized allowlisting play.
• SentinelOne: SentinelOne provides autonomous endpoint protection via its Singularity platform with EDR, XDR, and identity threat detection. Competes for the same enterprise endpoint budget as White Cloud Security, but with a detection-led (rather than default-deny) architecture.
• Trend Micro: Trend Micro offers endpoint security, server protection, and application control across enterprise environments. Competes with White Cloud Security for endpoint budget in mid-market and enterprise buyers but is a broad-portfolio incumbent rather than a focused allowlisting vendor.
• Microsoft Defender for Endpoint / Application Control: Microsoft Defender includes Windows Defender Application Control (WDAC) for allowlisting. Bundled into the broader Microsoft security stack, it competes with White Cloud Security's Trust Lockdown for any Microsoft-centric enterprise, particularly in regulated and government segments.
• VMware Carbon Black: Carbon Black (now VMware/Broadcom) provides endpoint detection and application control capabilities. Listed by White Cloud Security as a direct comparison; overlaps in endpoint security buyers but is part of a broader virtualization and security portfolio.

Direct peers

• ThreatLocker: ThreatLocker is a direct competitor offering application allowlisting/ringfencing with a default-deny model. The two companies explicitly compare against each other on White Cloud Security's comparison page, indicating closely aligned zero-trust application-control positioning for the same buyer.
• Airlock Digital: Airlock Digital provides application allowlisting and execution control for Windows, macOS, and Linux endpoints. Competes in the same zero-trust application-control niche, particularly with government and defense customers that demand rigorous endpoint control.
• PC Matic: PC Matic offers application allowlisting as its primary endpoint-security differentiator with a default-deny posture. Comparable to White Cloud Security in targeting prevention-first outcomes over signature-based detection, primarily in SMB and regulated segments.

Emerging players

• Cybereason: Cybereason offers an EDR/XDR platform focused on endpoint protection and attack prevention. While primarily detection-led, it competes in the same enterprise endpoint conversations where White Cloud Security positions its zero-trust application-control story.
• Deep Instinct: Deep Instinct applies deep-learning-based prevention to endpoint security, taking a prevention-first stance against ransomware and zero-day malware. Comparable to White Cloud Security's prevention narrative and zero-trust philosophy but uses ML-based detection rather than hash-based allowlisting.
