QuDef and Singapore-based The Thought Projects (TTP) have signed a memorandum of understanding to bring QuDef’s SQOUT quantum threat-intelligence platform to Singapore and the broader Asia-Pacific market. The announcement describes a planned collaboration—not a completed regional rollout, a published customer deployment, or a joint evaluation that has already certified a QKD system.
The proposed approach pairs SQOUT’s structured threat and risk analysis with TTP’s laboratory testing of commercial quantum key distribution (QKD) systems on actual hardware. That combination could help organizations examine both modeled attack paths and implementation weaknesses, but it is not a blanket security guarantee.
What the partnership is intended to do
Under the MOU, Netherlands-based QuDef and Singapore-based TTP intend to make SQOUT available in Singapore and across the broader Asia-Pacific market. The announcement does not give a launch date or establish availability in every country in the region. The Quantum Insider reported the agreement on October 13, 2026.

QuDef describes it as a way to model system architectures, identify implementation risks and potential attack paths, and prioritize mitigations. TTP’s reported contribution is laboratory evaluation of relevant issues against commercial QKD equipment using white-box, grey-box, and black-box approaches.
#1 Best Overall
In practical terms, the proposed workflow is analysis followed by hardware-focused testing: identify risks that matter to a particular deployment, then investigate relevant ones on the system itself. The announcement does not say that every modeled risk will be tested, or that the work has already been performed for a customer.
Why protocol security is not the same as product security
QKD protocols and the devices that implement them are different objects of analysis. A security proof can establish properties under stated assumptions; it does not, by itself, show that a physical product satisfies those assumptions or that its complete implementation is free of exploitable weaknesses.
In a June 2026 product announcement, QuDef cited protocols including BB84, BBM92, continuous-variable QKD (CV-QKD), and measurement-device-independent QKD (MDI-QKD) as theoretically secure under their underlying assumptions. The same announcement discussed potential implementation concerns such as side channels, detector blinding, Trojan-horse attacks, assumption violations, and implementation gaps. These are reasons to examine the real devices and deployment, not evidence that a particular product is vulnerable or that SQOUT prevents such attacks. QuDef’s June 1, 2026 announcement presents this rationale from the company’s perspective.
What SQOUT and TTP’s testing can contribute
Structured threat and risk analysis
QuDef says SQOUT can map system architectures and assess attack paths, then help teams prioritize mitigations. It describes risk scoring as compatible with ISO/IEC 27005 and as evaluating likelihood and impact across attack kill chains. Compatibility is not the same as ISO certification or independent validation.
The partnership announcement names QBuilder for device-level analysis, QNetwork for network-level analysis, and QAnalyser for “what-if” analysis. QuDef’s June product announcement describes QBuilder, QAnalyser, and QKill as core modules, while listing QNetwork, QAssessment, and QCompliance on a roadmap. Because the two descriptions differ, buyers should confirm the current module set and availability directly with QuDef rather than assume every named capability is currently offered.
Hands-on evaluation of hardware
TTP’s reported white-box, grey-box, and black-box methods indicate different levels of access to the system under evaluation. The announcement does not define the precise access, test procedures, or deliverables for each method. Organizations should therefore establish those details for the specific engagement rather than infer a standardized test package from the labels.
The value of combining the two activities depends on scope: the assessment needs to match the actual device, software, network architecture, and operating conditions. A report about one configuration should not be treated as proof about a different model or deployment unless the evidence supports that extension.

What the published figures do—and do not—show
The partnership announcement says SQOUT contains the following knowledge-base elements. These figures are company/partner-reported counts, not independently audited measures of security effectiveness or coverage.
Best Value
| Item | Count stated in the 2026 partnership announcement |
|---|---|
| Attack techniques | 149 |
| Countermeasures | 191 |
| Quantum protocols | 34 |
| Vulnerabilities | 123 |
| Security proofs | 12 |
| Hardware components | 124 |
| Software elements | 29 |
QuDef also reported that 100% of the QKD systems it had assessed by June 1, 2026 had vulnerabilities unknown to operators or not yet mitigated. The company release does not state the sample size, selection criteria, detailed methodology, or independent validation. This is a claim about the systems QuDef assessed—not about all QKD systems generally.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Deployment options and intended users
QuDef says SQOUT is offered as software as a service (SaaS) or as an on-premises virtual machine for sovereign and classified environments. Its product announcement also describes a QuDef-delivered assessment service and a free open-access edition; full-platform trial licenses are available by contacting the company. Those are QuDef’s product descriptions, not an independent determination that a particular configuration meets any organization’s classification, sovereignty, or compliance requirements.
QuDef positions the platform for organizations deploying, integrating, certifying, or defending quantum communication systems. For institutional buyers, the SaaS-versus-on-premises choice should be considered alongside data handling, access controls, system boundaries, and the organization’s own security requirements. The announcement supplies no pricing or customer-specific terms.

Questions to settle before commissioning an assessment
The announcements do not publish a QuDef–TTP procurement framework. For a meaningful evaluation, an organization should get clear answers to these scope and assurance questions before relying on any result:
- What is in scope? Specify the QKD device, protocol, software, network topology, interfaces, and operating configuration to be assessed.
- What access will testers have? Agree whether the work is white-box, grey-box, or black-box and document what information, components, and interfaces are available.
- Which risks are modeled and which are tested? Distinguish architecture and threat analysis from hands-on laboratory testing, and identify how each priority finding will be investigated.
- What evidence will be delivered? Establish the expected findings, supporting evidence, severity rationale, remediation guidance, and any retesting process.
- What does the conclusion apply to? Confirm whether findings cover only the tested hardware and configuration or support a broader claim, and ask what assurance criteria—if any—are being applied.
- How will sensitive information be handled? For SaaS or on-premises work, clarify data storage, access, retention, and deployment responsibilities against the organization’s requirements.
What has not been established
The available announcements do not name customers, document contracts, set a rollout timetable, confirm country-by-country availability, publish prices, or report completed TTP evaluations or joint test results. They also do not establish independent certification of SQOUT, TTP’s testing, or any named QKD product. The MOU signals an intended collaboration; it is not evidence that a particular system has passed assessment.
