What is Proton Bridge?
Proton Bridge is in pure maintenance: security patches and RFC compliance fixes dominate 2026
Proton Bridge has shipped six releases since February, none of which introduce user-visible features. The work is security vulnerability patching (August 2026 CVEs), RFC3501 IMAP compliance fixes, Go toolchain upgrades, and bug fixes in the Gluon IMAP server component. The v3.24.0 cycle added IMAP connection limiting and buffer pooling for message decryption — the most substantive user-affecting work in the reviewed period.
What is Krisp?
Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.
Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.

Proton Bridge is in pure maintenance: security patches and RFC compliance fixes dominate 2026
◆ Current state
Proton Bridge has shipped six releases since February, none of which introduce user-visible features. The work is security vulnerability patching (August 2026 CVEs), RFC3501 IMAP compliance fixes, Go toolchain upgrades, and bug fixes in the Gluon IMAP server component. The v3.24.0 cycle added IMAP connection limiting and buffer pooling for message decryption — the most substantive user-affecting work in the reviewed period.
◆ Where it's heading
Proton Bridge is in a sustain phase. The Gluon subsystem is getting more robust error reporting, CPU/memory bounds on the RFCP parser, and feature flags for controlled rollouts — signals of hardening a component that has historically caused reliability issues. No new end-user capabilities are visible in the roadmap from the changelog alone.
◆ Prediction
The next release will likely be another security or compatibility patch. Meaningful feature expansion would require Proton to signal a direction change for Bridge publicly, and nothing in this changelog points toward one.
Krisp
5.0COMMS
Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.
◆ Current state
Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.
◆ Where it's heading
The update cadence and content point at enterprise expansion: each weekly batch adds granular admin controls, API access for audit data, and new BPO visibility tools. Voice Translation language coverage is widening consistently. Deepfake risk visibility—added in the most recent batch—signals Krisp moving into a trust-and-compliance layer for AI-assisted calls, not just audio quality.
◆ Prediction
The deepfake detection work is nascent; expect it to grow into a standalone compliance dashboard. Enterprise RFPs increasingly require call-authenticity guarantees, and Krisp's audio-layer position gives it a defensible angle on that problem that CRM or WFM vendors can't replicate.
