Omnisec was a manufacturer of voice, fax and data encryption systems, based in Dällikon (Switzerland). The company was established 1 in 1987 by Dr. Pierre Schmid, a former employee of Gretag, and was first owned by Urs Ingold. The company was initially based in Regensdorf, the hometown of Gretag, and had acquired the sales rights of Gretag cryptographic equipment for the international governmental market, along with the ownership of some Gretag patents.

According to their own account, Omnisec was not bound by export restrictions — it was based in neutral Switzerland — and was able to supply its products to any government and army in the world [1]. On 25 November 2020 however, the Swiss SRF television program Rundschau revealed that for many years, Omnisec had been under full control of the American intelligence services CIA and NSA, and had sold weakened equipment 2 to its customers, even in Switzerland [2]. The latter was discovered by the Swiss commission that investigated the role of the Swiss Government in relation to competitor Crypto AG, which had been owned jointly by the BND and the CIA [3].
