About
Excellence in COMSEC – Discreet. Exclusive. Reliable. Personal.
Founded in 1995, ICSL is a trusted Austrian provider of high-assurance communication security (COMSEC) solutions for voice, video, chat, and data.
ICSL’s speciality is making the best even better — delivering customised solutions tailored to client needs, built on certified and proven technologies rather than reinventing the wheel.
The company’s sole focus lies in secure communication—delivered through intuitive solutions that combine practical usability with uncompromising security. The highest level of protection is provided, meeting stringent requirements for classified use—as confirmed by approvals from organisations such as NATO. Cryptographic algorithms implemented exceed CNSA standards for top-secret security, with post-quantum cryptography already in the implementation phase.
ICSL accepts every challenge when it comes to protecting clients’ information and communication. There is nothing to fear—when the possibilities and framework conditions are properly understood.
Even advanced threats such as Pegasus and similar spyware can be countered effectively.
Solutions are offered that do not permanently store any data on commercial off-the-shelf (COTS) devices (classification levels: RESTRICTED, CONFIDENTIAL). These applications have been in use and tested over many years, validated by clients, with not a single incident, vulnerability, or exposure ever reported. Additional options include hardened operating system variants, fully air-gapped architectures, and even mobile phones and laptops that are either adapted or entirely custom-built in collaboration with the client—suitable for use up to classification level SECRET.
