What is Krisp?
Krisp goes free-to-try on Call Center AI while deepfake detection lands in live calls
Krisp has repositioned from a consumer noise-cancellation app into a Call Center AI platform targeting BPOs and enterprise contact centers. The product now bundles real-time Accent Conversion, Voice Translation across Cantonese, Spanish, and Japanese, AI-powered QA scoring, deepfake risk detection, and conditional call recording under a single call-center offering. Admin controls and compliance tooling — live call audit enforcement, SCIM management, rule-based recording — signal that the enterprise layer is being built in earnest.
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.

Krisp goes free-to-try on Call Center AI while deepfake detection lands in live calls
◆ Current state
Krisp has repositioned from a consumer noise-cancellation app into a Call Center AI platform targeting BPOs and enterprise contact centers. The product now bundles real-time Accent Conversion, Voice Translation across Cantonese, Spanish, and Japanese, AI-powered QA scoring, deepfake risk detection, and conditional call recording under a single call-center offering. Admin controls and compliance tooling — live call audit enforcement, SCIM management, rule-based recording — signal that the enterprise layer is being built in earnest.
◆ Where it's heading
The free-to-try move on Call Center AI signals a push toward bottoms-up enterprise adoption: let agents and supervisors experience the product before procurement gets involved. The accelerating cadence of feature additions — deepfake detection, multi-language expansion, alerts integrations — suggests Krisp is racing to build a defensible platform before noise cancellation gets commoditized by larger unified-comms players. QA automation and compliance tooling point toward displacing point solutions that currently sit alongside CCaaS platforms.
◆ Prediction
The next move is likely a self-serve onboarding flow paired with usage-based pricing. The free-to-try gate is in place, the admin layer is built, and the missing piece is a conversion path that doesn't require a sales conversation.
Proton Bridge
5.0COMMS
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.
