CounterTack

CounterTack, Inc. was a Waltham, Massachusetts endpoint detection and response (EDR) vendor whose Sentinel and Endpoint Threat Platform products applied behavioral analysis, memory forensics and machine learning to detect zero-days, rootkits and advanced persistent threats. In June 2018 CounterTack acquired its channel partner GoSecure, a managed detection and response (MDR) provider, and in March 2019 rebranded the combined company as "GoSecure powered by CounterTack"; the CounterTack name has since been retired in favour of GoSecure, which today markets a managed extended detection and response (MXDR) service and the GoSecure Titan platform covering EDR, IDR, NGAV, SIEM and professional services. The CounterTack surface is therefore historical: countertack.com still resolves to GoSecure infrastructure but serves no valid certificate, and the living platform is customer-only behind a Keycloak single sign-on at titan.gosecure.net.

CounterTack publishes 1 API on the APIs.io network. Tagged areas include Company, Security, Cybersecurity, Endpoint Security, and Endpoint Detection and Response.

CounterTack’s developer surface includes support, authentication, and 16 more developer resources.

  description: 'A customer-only HTTP API host operated by GoSecure (formerly CounterTack) behind the GoSecure Titan platform.
    The host answers HTTP 401 on every path probed — including /robots.txt and every /.well-known/ path — so no anonymous
    discovery, OpenAPI document, or reference documentation is reachable. Its identity layer is public: the Titan single sign-on
    is a Keycloak deployment at login.gosecure.net whose OpenID Connect discovery document for the gosec-titan realm is served
    anonymously and is captured in this repository. No public developer portal, API reference, SDK, pricing page, or rate-limit
    documentation could be found for this API.'

  detail: CounterTack now trades as GoSecure, and its live Titan API host api.gosecure.net returns HTTP 401 on every path
    probed — including /robots.txt and every /.well-known/ path — while the Titan console sits behind a Keycloak tenant login,
    so the contract and reference are reachable only by an existing GoSecure customer.
