Cybersecurity, custom software, hardware and high-risk consulting. Built by a combat veteran, not learned from YouTube.
From cyber security audits to dedicated hardware - we deliver technology that works in any conditions.
Security audits, penetration testing, infrastructure hardening, vulnerability analysis and building security policies for companies and institutions.
Dedicated applications and systems designed for specific client requirements. Secure code, scalable architecture, full control over data.
Design and prototyping of dedicated electronic devices, IoT systems, communication modules and embedded solutions.
Professional consulting in personal and operational security in high-risk areas. Planning, training, evacuation procedures.
Collection and analysis of information from open sources, digital intelligence, threat profiling, reputation monitoring and operational support.
Building and auditing encrypted communication systems, VPNs, mesh networks, off-grid messengers and surveillance-resistant communication infrastructure.
Systems we build, test and deploy ourselves.
Encrypted comms over cheap DMR radio. No cellular carrier, no internet.
Android + DMR radio + custom protocol. Messages are encrypted inside the app before reaching the phone OS, so even a Pegasus-infected device cannot expose them. Works off-grid, in the field, in areas with no coverage.
Self-hosted E2EE messenger on your own server. No Matrix, no Big Tech.
Download the app, point it at your VPS, provide SSH — Cyclone deploys and secures the server automatically. No sysadmin knowledge needed. Optional 24/7 monitoring available.
Data over laser beam. No RF emissions.
Point-to-point line-of-sight communication. High throughput, hard to detect or jam. For temporary, mobile links and situations where radio silence matters.
Custom SDR radio with channel hopping and voice encryption.
Full firmware + software stack, web config panel, 400+ channel hops per second, AES-256-GCM. Markers go straight to the map. RX-only mode means zero emission — the radio is undetectable.
Drone as a mobile LTE/mesh node.
Dual-use tech: from SAR and infrastructure monitoring to tactical applications. Used in Ukraine by both sides of the conflict. Geran-5 runs on LTE + mesh. Identical software was used in operation "Pajęczyna".
Custom scripts for red team and penetration testing.
Exploit development, custom C2, AV/EDR evasion, pivoting, reverse engineering. Built by someone for whom OSCP/OSCE/OSEP/OSWE are a starting point, not the goal. Experience from Israeli cyber firms, including Haifa.
Detection of advanced spyware on iOS and Android.
Mobile forensics, network traffic analysis, IoCs, system anomalies. Detection of Pegasus, Predator, Hermit, KingSpy. Chief R&D worked for a cybersecurity firm based in Haifa.
