What is Knock?

Knock is hardening for enterprise buyers while its agent takes over the analysis work.

Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

What is Snort 3?

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

Knock is hardening for enterprise buyers while its agent takes over the analysis work.

◆ Current state

Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

◆ Where it's heading

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.

◆ Prediction

Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

◆ Current state

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

◆ Where it's heading

Snort is adapting an inspection engine built for readable traffic to a network where most of it is not. The investment is in inferring application identity from what remains visible, and in doing so on flows the sensor joined late. Alongside that, output is becoming more machine-consumable, with appid in alert_json, binary flow state dumps, and new DNS counters. The C codebase is being hardened continuously, which suggests fuzzing and sanitizer work running behind the feature stream.

◆ Prediction

QUIC handling has moved from an extractor to an appid preference in consecutive releases while midstream detection keeps widening; extending the same treatment to more encrypted protocols is the clearest continuation these entries support.
