What is Proton Bridge?
Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.
After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.
What is Krisp?
Krisp is repositioning from noise cancellation to a contact-center voice-AI platform
Krisp's updates are now almost entirely 'Call Center AI': a new Voice Security line against AI voice fraud (deepfake detection, agent voice protection), expanding Voice Translation, Speech Analytics with Salesforce-fed scoring, Accent Conversion, and admin controls for translated calls. The consumer noise-cancellation roots have receded from the feed.

Proton Bridge
2.5COMMS
Proton Bridge has re-accelerated, with a quality-and-security pass across error UX, FIDO2, and Go modernization.
◆ Current state
After a long pause through mid-2025, Proton Bridge resumed steady releases in early 2026 and has now shipped four versions in five months (v3.22 through v3.25). The work is uniformly internal: friendlier error messages, a Go 1.26 toolchain bump, FIDO2 path fixes, IMAP robustness, certificate-chain validation tightening, and the March 2026 security-patch sweep. Visible user-facing additions are limited to MacOS26 icon support and quality-of-life polish.
◆ Where it's heading
The product is in active maintenance mode rather than feature expansion. Investment is going into making the local sync layer more robust — mailbox conflict resolution, IMAP IDLE kill switch, vault retries on Linux — and the auth surface harder, with FIDO2 polish and TLS pin scoping. The arc reads as catching up on technical debt and shoring up security posture after a quieter year, not reshaping the product.
◆ Prediction
Expect the v3.2x cadence to continue with similar bug-fix and security flavor: more Go toolchain work, incremental IMAP edge-case handling, and continued error-UX tightening. The release notes do not surface anything that would hint at a v4 reshape or a meaningful new capability in the near term.

Krisp is repositioning from noise cancellation to a contact-center voice-AI platform
◆ Current state
Krisp's updates are now almost entirely 'Call Center AI': a new Voice Security line against AI voice fraud (deepfake detection, agent voice protection), expanding Voice Translation, Speech Analytics with Salesforce-fed scoring, Accent Conversion, and admin controls for translated calls. The consumer noise-cancellation roots have receded from the feed.
◆ Where it's heading
The product is moving up-market into contact centers, stacking real-time voice translation, analytics, agent assist, and now fraud defense into a CCaaS-adjacent suite. Voice Security is the newest and sharpest extension of the capability surface.
◆ Prediction
Expect Voice Security and Voice Translation to keep expanding, with deeper CRM integrations like the Salesforce link feeding analytics scoring.
