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 Roundcube?
After four years, Roundcube 1.7 lands — and the release stream is otherwise all CVEs
Roundcube maintains two lines in lockstep: 1.6 as LTS and 1.7 as stable, with security fixes released to both on the same day. The vulnerability stream is heavy and varied — stored XSS via an unescaped attachment MIME type (CVE-2026-54432), a pre-auth SQL injection in the virtuser_query plugin, CSS injection through SVG animate, SSRF bypasses via local address URLs, an infinite loop in the TNEF decoder. Version 1.7.0, released in May after almost four years of development, is the only feature release in the window.
Krisp vs Roundcube: editorial side-by-side
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.
Roundcube
5.0COMMS
After four years, Roundcube 1.7 lands — and the release stream is otherwise all CVEs
◆ Current state
Roundcube maintains two lines in lockstep: 1.6 as LTS and 1.7 as stable, with security fixes released to both on the same day. The vulnerability stream is heavy and varied — stored XSS via an unescaped attachment MIME type (CVE-2026-54432), a pre-auth SQL injection in the virtuser_query plugin, CSS injection through SVG animate, SSRF bypasses via local address URLs, an infinite loop in the TNEF decoder. Version 1.7.0, released in May after almost four years of development, is the only feature release in the window.
◆ Where it's heading
The arc is a long-lived webmail codebase paying down structural risk. 1.7.0's headline changes are defensive rather than user-facing: a mandatory public_html/ entry point so installations aren't exposed by default, improved OAuth2/OIDC support including discovery and logout, removed code bloat and automated code style and quality checks. Everything since has been paired security releases across both lines, several of them reporting classes of bug — sanitizer bypasses, injection through plugin queries — that the 1.7 hardening work is aimed at. Expect the security cadence to stay high while the 1.6 LTS remains supported.
◆ Prediction
Expect continued same-day paired security releases on 1.6 and 1.7, with 1.7.x accruing incremental OIDC and sanitizer hardening before any 1.8 work becomes visible.
