Proton's password manager passes audit by top security firm

The linked press release makes no mention of whether or not server side code was audited only stating that: > This year, Recurity Labs(new window), an ISO 27001-certified IT security consultancy, tested everything a Proton Pass user interacts with: the Proton Pass browser extensions(new window), mobile and desktop applications(new window), and Command Line Interface(CLI). This is still excellent to see. However, personally with something as sensitive as a cloud based password manager I would like to see an audit of that server side code as well, for further transparency. Also of note: It does not appear that this most current audit is available at the time of posting at the audit list link provided by Proton in the article. Only a Cure53 audit from June of 2023 shows up for me. * An open source privacy company | Proton
