Our certifications & accreditations

Commercial Product Assurance

CPA Certified logo

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.”

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.

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 organisations involved. Egress Switch 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 authorised for sales on the CloudStore (G-Cloud).

International Privacy Verification (IPV) programme

Whilst the Court of Justice of the European Union (CJEU) and the Swiss Federal Data Protection and Information Commissioner (FDPIC) ruled the EU-U.S. and Swiss-U.S. Privacy Shield Frameworks invalid in the summer of 2020, we remain committed to the Privacy Shield Principles.  In recognition of our continued commitment, in October 2020 we self-certified with the International Privacy Verification programme (IPV). The IPV’s assessment criteria are aligned with those of the Privacy Shield and therefore by certifying with the IPV we are able to continue to demonstrate our compliance with the core Privacy Shield Principles in relation to the protection of personal data transferred outside of the UK and EU.
