There is no information in the documents seen by SPIEGEL to suggest that the companies whose products are mentioned in the catalog provided any support to the NSA or even had any knowledge of the intelligence solutions. “Cisco does not work with any government to modify our equipment, nor to implement any so-called security ‘back doors’ in our products,” the company said in a statement. Contacted by SPIEGEL reporters, officials at Western Digital, Juniper Networks and Huawei also said they had no knowledge of any such modifications. Meanwhile, Dell officials said the company “respects and complies with the laws of all countries in which it operates.”
Cooperation such that telecom equipment providers provide in support of CALEA would be needed for this to work.
