What is Krisp?
Krisp turned noise cancellation into a contact-center AI stack — and now defends it against deepfakes.
Krisp's changelog is almost entirely Call Center AI: Accent Conversion, Voice Translation, Speech Analytics, and a Voice Security line that detects synthetic voices and verifies agents. The release rhythm is two-track — versioned desktop builds carrying model upgrades, and near-weekly web batches carrying admin, analytics, and access controls. Most of the recent web work is aimed at administrators rather than agents on the phone.
What is Openfire?
Openfire's 5.1 line pairs XMPP channel binding with a steady cleanup of its own crypto
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.

Krisp
5.0COMMS
Krisp turned noise cancellation into a contact-center AI stack — and now defends it against deepfakes.
◆ Current state
Krisp's changelog is almost entirely Call Center AI: Accent Conversion, Voice Translation, Speech Analytics, and a Voice Security line that detects synthetic voices and verifies agents. The release rhythm is two-track — versioned desktop builds carrying model upgrades, and near-weekly web batches carrying admin, analytics, and access controls. Most of the recent web work is aimed at administrators rather than agents on the phone.
◆ Where it's heading
The center of gravity has shifted from processing the audio to governing the operation around it. Voice Security opened a second buying reason beyond call quality, and the newer web releases — enterprise analytics sharing, agent screen recording, audit and access controls, automated data retention cleanup — read as a BPO-facing compliance layer taking shape. Krisp is positioning as infrastructure a contact center buys once and administers, not a per-seat audio utility.
◆ Prediction
Voice Security has moved from launch to paid trial in roughly six weeks, so expect it to reach general availability with pricing attached as the next step. The analytics and recording work points the same direction: more supervisor-facing surfaces bundled into the enterprise portal rather than new agent-side audio features.

Openfire's 5.1 line pairs XMPP channel binding with a steady cleanup of its own crypto
◆ Current state
Six releases across the 5.0 and 5.1 lines, each a long list of numbered improvements and bug fixes. The 5.1.0 release is the substantive one: support for channel binding, an admin console page for reviewing failed server-to-server connection attempts, visible S2S ports, and removal of a hardcoded initialization vector and a weak SHA-1-derived Blowfish key. The rest is multi-user chat correctness, pubsub behaviour and dependency currency.
◆ Where it's heading
Two consistent threads run through the window: replacing the older cryptographic shortcuts still sitting in the codebase, and making federation failures diagnosable rather than silent. Multi-user chat and pubsub keep generating the highest volume of fixes, which is a fair map of where a working XMPP server actually spends its time.
◆ Prediction
Expect the 5.1 line to continue with MUC and pubsub fixes plus further dependency upgrades, with any remaining legacy crypto paths the most likely target for the next round of hardening.
