Hub Cyber Security Ltd. (HUBCZ)

Hub Cyber Security Ltd. trades on the NASDAQ under three distinct ticker symbols — HUBC for common shares, HUBCW for warrants expiring in 2028, and HUBCZ for additional warrants. The company itself is relatively unknown to retail investors, but its core mission touches some of the most important technical challenges in modern computing: how to keep sensitive data secret even while computers are actively processing it, and how to move that data safely between systems without exposing it to eavesdropping or theft.

The business of selling security is an old one, but confidential computing is a newer frontier. Traditional security assumes that if you control the hardware and the operating system, you have security. Encrypt the database, lock the physical servers, hire trustworthy employees. But in a world where corporations run on cloud systems owned by other companies, where contractors access sensitive data, where even inside your own data center multiple tenants might share the same hardware, that assumption collapses. A cloud provider’s administrator, a dishonest engineer, a compromised system, or a nation-state with legal power over a data center can all bypass encryption and see what is inside.

Hub’s platform addresses this by building what amounts to a cryptographic safe inside a computer itself. The data stays encrypted even while it is being processed. The algorithm runs on the data in encrypted form, producing an encrypted result that only the authorized person can decrypt. From the perspective of anyone else — the cloud provider, the system administrator, potential intruders — the actual data remains incomprehensible noise. This is not entirely new mathematics; academics have known how to do this for decades. What Hub sells is a pragmatic, performant, commercially supportable implementation of these ideas.

The technical approach Hub uses centers on hardware security features that modern processors now include. Chips from Intel and others have built-in mechanisms called secure enclaves that create isolated execution environments protected by hardware. Hub’s software platforms leverage these hardware features to build systems where data can be processed securely in the cloud, on a partner’s servers, or anywhere else, without the data ever being visible to the human operators. The company also provides hardware accelerators and specialized processors optimized for encrypted computation, because the overhead of working with encrypted data is substantial — a calculation on encrypted numbers takes much longer than the same calculation on plain text.

This is a genuinely important capability for certain customers. Financial institutions that must protect customer account information, healthcare providers that handle medical records, government agencies that work with classified data, technology companies that process proprietary algorithms — all of these face the problem of needing to use external compute resources (cloud infrastructure, contractor services, outsourced analytics) while being unable to actually trust those resources with unencrypted data. Hub’s technology offers a middle path: use cloud computing at scale while mathematically guaranteeing that your data stays secret.

The business model is typical for enterprise security software. Hub sells licenses to use its platform, usually for a three-to-five-year term, with annual or monthly billing. Implementation and integration with customer systems requires professional services. The company also partners with cloud providers — major infrastructure companies that want to offer confidential computing as a service to their own customers — and provides white-labeled or integrated solutions. This creates multiple revenue streams: direct licensing from enterprises, revenue sharing from cloud platform partnerships, and professional services implementation fees.

Revenue growth depends on penetration of a market that is still nascent. Confidential computing is not yet as widely deployed as the size of the potential problem would suggest. Most companies still rely on conventional encryption and trust-based access controls. Shifting to confidential computing requires rearchitecting how systems handle data, which is expensive and disruptive. Hub’s job is to make that transition easier and faster than competitors can, and to win a larger share of the enterprises that do decide to move.

The company faces genuine competitive pressure. Large cloud providers like AWS, Microsoft Azure, and Google Cloud all have built confidential computing capabilities into their platforms. Apple, IBM, and others have also developed relevant technologies. These larger competitors have scale, installed customer bases, and far deeper engineering resources. They can absorb confidential computing as a feature at low marginal cost, whereas Hub has to build an entire business around it. At the same time, smaller startups continue to emerge with specialized approaches to similar problems — homomorphic encryption, secure multi-party computation, differential privacy. The field of privacy-preserving computation is crowded and young, with no clear winner.

Hub’s actual strength is in execution and customer relationships. As an Israeli firm, it benefits from an ecosystem that produces talented cryptographic and security engineers. The company has been building security technology since 2010, predating the recent wave of interest in confidential computing, which gives it accumulated expertise and a head start on some competitors. Whether that translates to sustained business success depends on whether large enterprises decide that confidential computing is worth the cost and complexity, and whether Hub can win and retain those customers faster than larger rivals can build competing solutions.

Investors examining the company should study its customer base and contract terms from SEC filings. How long are customer relationships lasting? Are big contracts being renewed? What is the mix between new business and expansion within existing accounts? Hub’s revenue is growing, but growth in emerging infrastructure software can be deceptive — it can look strong in absolute terms while losing ground to well-capitalized competitors. The company also faces the perennial challenge of security companies: if a vulnerability is discovered in the cryptographic or hardware security mechanisms that underpin the platform, customer confidence could evaporate overnight. Hub must maintain high technical standards and respond rapidly to any issues that arise. The warrant structures (HUBCW and HUBCZ) add a layer of leverage and volatility for investors seeking exposure to the company; research should include understanding the terms, expiration dates, and whether they are in or out of the money relative to the underlying share price.
