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.
What is Rivet?
Rivet ships OTel tracing, BYOC deployment, and MCP integration in a single month, building production-grade infrastructure for AI agents.
Rivet has shipped four significant platform capabilities in September: OpenTelemetry with cross-actor ray IDs that correlate work across actors running for days, BYOC deployment into customer-owned AWS or GCP VPCs, an MCP server letting AI developer tools manage actors directly, and durable real-time streams. The August Dynamic Apps feature added user-generated app deployment via V8 isolates. Each of these targets teams running production agentic systems at scale.

OSSEC
3.8DEVOPS
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.
Rivet
10.0DEVOPS
Rivet ships OTel tracing, BYOC deployment, and MCP integration in a single month, building production-grade infrastructure for AI agents.
◆ Current state
Rivet has shipped four significant platform capabilities in September: OpenTelemetry with cross-actor ray IDs that correlate work across actors running for days, BYOC deployment into customer-owned AWS or GCP VPCs, an MCP server letting AI developer tools manage actors directly, and durable real-time streams. The August Dynamic Apps feature added user-generated app deployment via V8 isolates. Each of these targets teams running production agentic systems at scale.
◆ Where it's heading
Rivet is building the infrastructure layer that production agentic deployments need but that generic serverless platforms don't provide: durable actors, cross-span observability for long-running workflows, BYOC for enterprise compliance, and MCP for AI-native developer experience. The product is progressing from developer-friendly to enterprise-ready without sacrificing the self-hostability that distinguishes it from managed-only competitors.
◆ Prediction
The next likely moves are expanded compliance certifications (SOC 2 is the usual next step after BYOC) and a formal enterprise tier, given that BYOC and OTel are exactly the capabilities that precede enterprise procurement conversations.
