Q-Shield Sentinel: post-quantum readiness, honestly assessed. A customer sent you a post-quantum readiness questionnaire? Q-Shield drafts answers only where your own assessment or scan records back them, cites the record for each, and leaves the rest blank or marked for your direct answer. SENTINEL ECHO โ ANSWER THE QUESTIONNAIRE YOU WERE SENT โข Paste it or import a text file. Echo sorts each question: cryptographic inventory, standards and compliance, migration roadmap, crypto-agility or suppliers. โข It drafts an answer only where your assessment or saved scans back it, and each answer cites that record, so you can check it before sending. โข Unsupported questions come back blank, with the reason. Pricing, contract, SLA and supplier questions are marked "only you can answer this." โข Not AI: fixed rules โ the same questionnaire always gives the same result. โข Keys, certificates or passwords pasted by mistake are caught on your device before upload. โข Export the answers as a document. QRS 5-AXIS QUANTUM-RISK ASSESSMENT Three short steps give you a 0โ100 Quantum Resilience Score across five weighted axes: algorithm vulnerability, key-length safety, migration readiness, data exposure and compliance gap. Each result shows the algorithms most at risk, a radar chart, a prioritized roadmap to the NIST post-quantum standards (ML-KEM, ML-DSA, SLH-DSA), your Q-Day estimate and harvest-now-decrypt-later (HNDL) exposure, and an optional key-rotation check (Ghost-Key). Each result also states its scoring-method version and the basis of its numbers (your inputs, a model estimate or a what-if scenario). ASSESSMENT REPORT (Professional and Enterprise) A 22-page PDF Simulation Assessment Report. The app shows its report ID, page count and the SHA-256 fingerprint of the downloaded file. SENTINEL Shows how fresh each of five sources is: NIST, the GRI threat timeline, arXiv, your domain and your last assessment. Force Refresh never counts against your monthly assessments. THREAT INTEL AND SIRI โข HNDL threat map (figures: Professional and Enterprise), labelled as a model estimate, not measured traffic. โข Shor penetration simulator (Professional and Enterprise): eight attack-vector scenarios against your declared algorithms, with the weakest link. โข Siri: security health check, threat explanation, audit log โ status only, never secrets. A SIMULATION, NOT A CERTIFICATION A deterministic, rule-based simulation that maps your inputs to NIST post-quantum standards โ not an infrastructure audit, not a certification authority. RSA and ECDSA are not called broken today; they are exposed to data harvested now for later decryption. Q-Shield never asks for or stores your private keys, plaintext or passwords. PLANS โข Free: 3 assessments a month, recent history, 1 questionnaire sorted a month. โข Professional ($149.99/month): 100 assessments and 20 new PDF reports (22 pages) a month, 200 penetration simulations, 100 Echo drafts. โข Enterprise ($499.99/month, or annual through our sales team): the same features with higher monthly limits โ 500 assessments, 100 PDF reports, 1,000 simulations, 500 Echo drafts. Monthly counts refill on the 1st. Results you already have stay available. LEGAL Risk-assessment simulation based on mathematical modelling. Results are estimates, not a security certification, and do not guarantee protection against quantum attacks. Decisions based on them are your responsibility.

Encrypted Temp Storage

"Not even the operators can see your data." A self-destructing, zero-knowledge encrypted temporary storage for your large files. This is a dedicated app for securely and easily sending and receiving large videos and confidential documents from your smartphone. Say goodbye to the hassle of password-protected ZIP files and the security concerns of free file transfer services. [Key Features] โ Absolute Security (E2EE) Files are strongly encrypted (AES-GCM 256-bit) directly on your device before uploading. Only meaningless binary data is stored on our servers, making data leaks physically impossible even in the event of a breach. We cannot scan or view your files. โ Stable Handling of Large Files While mobile browsers often crash due to memory limits when handling multi-gigabyte files, our native app uses efficient streaming processes to securely encrypt and download heavy data without fail. โ Self-Destructs in 5 Days All uploaded data is physically and permanently deleted from our servers after 5 days. Leave no digital footprint behind. โ Perfect for "Self-Transfer" An extremely convenient tool for quickly sending large videos or photos taken on the go from your smartphone to your PC. โ Receive Files Without Logging In No account is needed just to receive files. Simply tap a shared link to securely decrypt and save the files directly within the app. *Note: The receiving and downloading features are completely free for everyone. To use the upload (send) feature, an account is required beforehand. *** Privacy Policy: https://qconp.com/#section-privacy-en Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Encrypted Temp Storage at none against Q's 3. Encrypted Temp Storage also leads on update cadence (every 2 days vs fortnightly) and iOS requirement (13.0 vs 26.0). On price, ads and device support there is nothing between them.
