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:

  • Threat actors: canonicalized across vendor naming schemes, so one campaign doesn't appear as five different actors
  • IOCs: defang-aware extraction that distinguishes real indicators from reference links
  • CVEs, targeted sectors, and severity: consistent fields on every report

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.

Signalis.watch features and specs

  • Structured threat feed
    Every report parsed into actors, CVEs, IOCs, sectors, and severity. One ranked feed instead of dozens of source sites
  • IOC feed API
    Machine-readable indicator feed with keyset pagination and OpenAPI spec; defang-aware extraction
  • Actor canonicalization
    Vendor naming schemes merged so one actor doesn't appear as five
  • Watchlist alerts
    Notifications when tracked actors, CVEs, or sectors appear in new reports
  • Weekly digest
    Email summary of the week's significant reports and trends
  • Curated source pipeline
    Sources continuously scored on extraction yield; low-signal feeds get cut
  • Grounded Q&A (Speculo)
    Ask questions over the corpus, answers with enforced citations to source reports

    Full pipeline on 7-day-delayed data, evaluate before paying

RxJava features and specs

  • Asynchronous Programming
    RxJava provides tools for composing asynchronous and event-based programs using observable sequences, making it easier to manage concurrent tasks.
  • Composability
    With RxJava, complex asynchronous workflows can be composed of simpler observable sequences, allowing for modular and reusable code.
  • Error Handling
    RxJava offers a wide range of operators and try-catch constructs to manage and respond to errors in a resilient manner.
  • Rich Operator Set
    RxJava comes with an extensive set of operators that can be used to filter, transform, and combine observable sequences for powerful data manipulation.
  • Backpressure Support
    The library provides the ability to handle backpressure, which helps manage situations where producers of data are faster than consumers.

Possible disadvantages of RxJava

  • Steep Learning Curve
    RxJava introduces a reactive programming paradigm that can be difficult for developers new to this approach to grasp immediately.
  • Complexity in Debugging
    The abstract nature of observables and operators can make it challenging to debug ReactiveX code compared to traditional imperative code.
  • Verbose Syntax
    Using RxJava often leads to more verbose code with chains of operators, which can decrease code readability if not well-documented.
  • Performance Overhead
    RxJava can introduce some performance overhead due to abstraction layers, which might not be suitable for all performance-critical applications.
  • Library Size
    For mobile applications, the size of the RxJava library can be a drawback if minimizing application size is a priority.

Questions & Answers

As answered by people managing Signalis.watch and RxJava.

What makes your product unique?

Signalis.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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.
