Signalis monitors curated CTI sources and extracts structured fields from every report. You read one ranked feed instead of many source sites.
Public threat reporting is scattered across vendor blogs, CERT advisories, and researcher posts, each with its own naming conventions and no consistent structure. Signalis ingests these sources continuously and processes every report through an extraction pipeline that identifies:
On top of the structured corpus: watchlist alerts for the actors and sectors you track, weekly email digests, grounded Q&A with enforced citations to source reports, and a machine-readable IOC feed API with OpenAPI spec.
Sources are continuously scored on extraction yield. Feeds that stop producing signal get cut, so the feed stays high-density.
Built by a former enterprise CTI practitioner (OpenCTI, MISP, EclecticIQ background) as the middle path between manually reading source sites and five-figure enterprise threat intel platforms.
Pricing: Free tier with the full pipeline on 7-day-delayed data. Real-time feed, alerts, and API from $29/mo. Teams with 5 seats, webhooks, and higher API limits at $69/mo.
React Engine Signalis.watchSignalis.watch's answer:
Signalis turns dozens of scattered CTI sources into one structured, ranked feed. Instead of skimming vendor blogs, CERT advisories, and researcher posts separately, you read a single stream where every report has been processed into structured fields: threat actors (canonicalized across vendor naming schemes), CVEs, IOCs, targeted sectors, and severity. IOCs are extracted with defang handling and are careful about what counts as an indicator, reference links are kept as references, not polluted into the IOC set. The result is a feed you can query like data, not a pile of articles: via the dashboard, watchlist alerts, weekly digests, or a machine-readable IOC API.
Signalis.watch's answer:
Most aggregators stop at collecting links. Signalis is built by a former enterprise CTI practitioner (OpenCTI/MISP/EclecticIQ background) and it shows in the details: actor names are canonicalized so "one campaign" doesn't appear as five actors, extraction quality is continuously measured against source-level yield metrics, and low-signal sources get cut. It's also priced for individual analysts and small teams, real-time structured feed, alerts, and IOC API access from $29/mo, where traditional threat intel platforms start at five figures. Free tier lets you evaluate the full pipeline on 7-day-delayed data before paying anything.
Signalis.watch's answer:
CTI analysts, SOC analysts, threat hunters, and security engineers at organizations too small for enterprise TIP pricing, or individual practitioners who want to stay current without maintaining their own feed pipeline. Also useful for MSSPs and consultants who need structured, citable threat reporting across many client sectors.
Signalis.watch's answer:
Signalis was built by a threat intelligence practitioner who spent years running enterprise CTI platforms and doing the same manual triage every morning: dozens of source sites, inconsistent naming, unstructured reports. The tooling that solved this was enterprise-priced and heavier than most teams need. Signalis is the middle path: an opinionated ingestion and extraction pipeline that reads the sources for you and outputs structured intelligence: one feed, every report structured.
Signalis.watch's answer:
FastAPI (Python) backend with PostgreSQL, a Next.js/Tailwind frontend, Redis for rate limiting, and an LLM-assisted extraction pipeline layered over deterministic regex IOC extraction with defang/refang handling. Auth via Supabase, deployed on hardened Linux infrastructure.

I was wondering to use paypal's React Engine (https://github.com/paypal/react-engine), but I have some doubts:. Source: over 4 years ago
