Success stories from clients who have leveraged Capzul's cybersecurity solutions to eliminate their external attack surfaces and ensure complete protection.
Large Multinational Enterprise
A large multinational enterprise using AI agents operating on the Model Context Protocol (MCP).
The AI agents communicate with each other and with external data sources via MCP over HTTP in a client–server architecture. While flexible, this architecture exposes AI agent servers to the public internet, creating a large and vulnerable attack surface that traditional security tools cannot fully protect.
Capzul combined two core technologies to create an attack-proof environment:
CapzulConnectPro completely hides and isolates servers, rendering them invisible to attackers and fully eliminating the attack surface. Establishes a quantum-safe, point-to-point “stealth tunnel” that encapsulates all traffic and bypasses the inherent vulnerabilities of traditional DNS.
Hackers cannot target what they cannot
discover
Post-quantum-ready cryptography against emerging threats
Deployed without code changes or complex reconfiguration
Supply Chain Security
Global supplier, a company specializing in medical and logistical data management, operating a global network of medical devices (endpoints).
Capzul delivered an embedded build incorporating two key components:
A server cloaking solution that fully hides infrastructure from external exposure.
External penetration attempts reduced from industry baseline of >1 to 0
Transitioned from edge host + firewall/VPN to single unit, reducing
SWaP and TCO
Measurable drop in patch tickets and faster site bring-up time
Encrypted CNCP tunnels simplify audits against RDC 430 and SNCM regulations
Seamless deployment without complex hardware or software
reconfigurations
More stable and reliable connection than conventional VPNs
Financial Services Industry
A major payment processing firm based in South America handling millions of transactions daily for a global network of merchants, banks, and financial institutions.
The financial sector’s current security is reactive and relies on vulnerable, fragmented systems.
The reliance on traditional VPNs and dedicated channels creates multiple single points of failure.
A single vulnerability can compromise the entire network, making it susceptible to supply chain, DDoS, and ransomware attacks.
Fragmented, reactive approach makes interconnected services vulnerable and the complex VPN setup makes adding new clients slow and costly.
Capzul provided a turnkey solution that removed all inbound exposure, ensuring that nodes cannot be discovered or scanned. This was achieved by using CapzulProtect for server cloaking and CapzulConnect for keyless, post-quantum tunnels.
Compromised third party software or code libraries cannot communicate externally due to Capzul’s Zero Trust network.
Capzul provides a secure, isolated, read-only data endpoint for regulatory bodies without exposing critical systems.
Capzul hides the server, eliminating any public IP address that could be targeted.
Segmented and isolated communication prevents attackers from moving between machines.
Capzul enforces end-to-end encryption even on insecure networks.
Capzul creates an impenetrable communication bubble to protect trading strategies.
Capzul creates an isolated overlay network for IoT devices, preventing unauthorized access to other systems.
Green Edge Computing Corp.
Green Edge Computing Corp. (GECCO), a company needing a rugged edge appliance that could withstand hostile environments and be invisible to internet threats.
Traditional edge boxes expose SSH/HTTPS listeners, making them vulnerable to scanning and probing. Bolting on firewalls and VPNs inflates costs, power draw, and creates a perpetual patch cycle. Legacy RSA/TLS stacks also risk mid-life crypto obsolescence.
GECCO embedded Capzul’s technology into its fanless EdgePod™ to create Capzul Frontier, a turnkey micro data centre that is post-quantum-ready and undiscoverable.
Server cloaking technology that makes nodes completely invisible to external threats.
Keyless post-quantum tunnels ensuring secure communication without exposed endpoints.
Delivered as a single image with no routable IPs, making the node undiscoverable.
Remote penetration attempts reduced from industry baseline of >1 to 0
Transitioned from multi-unit system to single 22 kg unit, yielding a 50-75% SWaP reduction
Perimeter hardware, licenses, and patch cycles removed, driving down
Total Cost of Ownership (TCO)
“No-ports-no-DNS” model aligns with IEC 62443, NIST 800-82, and EU DORA regulations
