What is Auth0?

Auth0 hands tenants a throttle on their own noisy apps

Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.

What is OSSEC?

A 20-year-old HIDS is being re-engineered for scale and modern crypto.

OSSEC has moved through three substantial releases in six months under Atomicorp maintainership. The 4.0.0 release broke backwards compatibility by making AES the default agent transport and modernized file integrity monitoring to SHA-256; 4.2.0 followed with a multi-threaded analysisd pipeline and a self-contained Windows agent installer. The work is concentrated in a small number of hands — most PRs in these releases carry a single contributor tag.

Auth0 hands tenants a throttle on their own noisy apps

◆ Current state

Custom Rate Limits enter Early Access, letting a tenant cap requests per second for individual clients or whole classes of them — third-party, CIMD — so one application cannot exhaust the tenant's Authentication API rate limit entitlement. Policies are configured through an API and can be rolled out in notify-only mode before they start blocking. It arrives in a dense window that also brought Flexible Password Policy to GA and Custom Prompts parity across social and enterprise connections.

◆ Where it's heading

Two threads dominate. One is agent and delegation infrastructure — Agents as Principal, Token Vault Privileged Worker, Custom Token Exchange session delegation — all still in Early Access. The other is tenant self-service: rate limits, blocklists, organization search and roles, global search. Auth0 is systematically converting things that required support intervention into API-configurable policy.

◆ Prediction

The Early Access items now stacking up, particularly the agent-identity pieces, are the obvious GA candidates next, following the Flexible Password Policy path from Early Access to general availability.

A 20-year-old HIDS is being re-engineered for scale and modern crypto.

◆ Current state

OSSEC has moved through three substantial releases in six months under Atomicorp maintainership. The 4.0.0 release broke backwards compatibility by making AES the default agent transport and modernized file integrity monitoring to SHA-256; 4.2.0 followed with a multi-threaded analysisd pipeline and a self-contained Windows agent installer. The work is concentrated in a small number of hands — most PRs in these releases carry a single contributor tag.

◆ Where it's heading

This is a modernization program, not feature expansion. The pattern across releases is removing decade-old constraints: single-threaded analysis, Blowfish crypto, MD5/SHA-1 integrity hashes, 2GB file limits, dependency-hunting Windows installs. Each release trades compatibility for correctness, and the project has been willing to force server-before-agent upgrade ordering to get there.

◆ Prediction

Expect the threading work started in 4.2.0 to extend further into the manager daemons, and continued removal of legacy crypto paths. Whether the Blowfish fallback survives another major version is the open question the entries don't answer.
