Commercial Product Assurance

Certificate No: 1433053936-3453

Issue date: November 11th, 2020 (to present)

Egress has held the UK Government CPA Foundation Grade as a certified email encryption product since 2014. This makes Egress suitable for sharing OFFICIAL and OFFICIAL-SENSITIVE under the current government classification policy. As a result Egress helps fill the gap between existing accredited government networks and external delivery partners, citizens and third sector businesses.

At the time of the award a NCSC spokesperson commented: "Egress’ innovative technology and commitment to demonstrating that it meets NCSC’s standards means that the end-user has confidence that they are selecting an email encryption product that has been approved by UK Government and is capable of protecting their organisation and the data they share from external threats.”

Common Criteria

Certificate No: P302

Issue date: August 8th, 2017

Many businesses and government institutions require formal assurance that the data security solutions they deploy meet their information assurance requirements. Common Criteria is an internationally recognized scheme for technology products, providing formal proof that security functionality within the solutions has been independently tested and verified to meet levels of assurance against government-backed security standards.

By benchmarking our technology against this independent, internationally recognized certification, our customers and partners can be assured that they are investing in highly resilient data security technology that has been designed to deliver protection to their organization, their staff, and the information they share.

Additional certificates are listed on the FIPS 140 Validation page

Details: Egress Protect client and server software utilizes FIPS validated libraries, permitting FIPS mode operation. The product utilizes FIPS standard AES-256 (FIPS 197) for message encryption and attachment encryption.

Specifically, the current shipping product only utilizes validated cryptography for message and attachment encryption via Microsoft software libraries which have approved FIPS validations. These are Microsoft Cryptographic Modules with FIPS Certificates1 #2937, #2936, #2606, #2605, and #1894 for libraries bcryptprimitives.dll, ncryptsslp.dll, cng.sys and RSAENH.dll on supported windows platforms. These libraries provide AES-256 in software, and per Microsoft and Intel, on supported Intel CPUs with AES-NI hardware instructions2, AES acceleration and execution in on-chip hardware.

References: Egress Protect use the following cryptographic libraries:

  1. Cryptographic Primitives Library (bcryptprimitives.dll and ncryptsslp.dll)
  2. Kernel Mode Cryptographic Primitives Library (cng.sys)
  3. Enhanced Cryptographic Provider (RSAENH.DLL)

Pan Government Accreditation (PGA)

Certificate No: G230.001 IL2

Issue date: August 15th, 2014

Infrastructure and services are increasingly shared by multiple Government Departments as a way of reducing costs. The accreditation of these systems can be complex, since different departments will have different threat profiles and risk appetites. The Pan Government Accreditation (PGA) service is provided by CESG to manage the combined risks efficiently on behalf of all public sector organizations involved. Egress Protect Software as a Service (SaaS) achieved full PGA accreditation in August 2014, making it suitable as a fully managed service for OFFICIAL electronic data sharing across UK Government and the wider supply chain. Note: Whilst the Certificate states that the Switch "service only supports HMG customers" this is in the context of Switch being authorized for sales on the CloudStore (G-Cloud).
